The root surface in human teeth: a microradiographic study. (1/479)

In an attempt to clarify the nature of the human cemento-dentinal junction, ground sections of incompletely formed and fully formed extracted teeth were prepared and their histology compared with their microradiographic appearances. The results showed that incompletely formed teeth possess distinctive surface layers outside the granular layer of Tomes. The evidence indicates that these layers are of dentinal origin; their presence during development supports previous explanations by the author of the hyaline layer of Hopewell-Smith and of so-called intermediate cementum. The results also indicate that the granular layer of Tomes does not represent the outer limit of root dentine. The relationship of these surface layers to the definitive cementum which is present in fully formed teeth was studied in both young and older patients. From the results it was concluded that cementum formation begins in the more apical region of the teeth at a time when root formation is well advanced, and that it spreads towards the crown rather than in the generally accepted reverse direction.  (+info)

A modern human pattern of dental development in lower pleistocene hominids from Atapuerca-TD6 (Spain). (2/479)

The study of life history evolution in hominids is crucial for the discernment of when and why humans have acquired our unique maturational pattern. Because the development of dentition is critically integrated into the life cycle in mammals, the determination of the time and pattern of dental development represents an appropriate method to infer changes in life history variables that occurred during hominid evolution. Here we present evidence derived from Lower Pleistocene human fossil remains recovered from the TD6 level (Aurora stratum) of the Gran Dolina site in the Sierra de Atapuerca, northern Spain. These hominids present a pattern of development similar to that of Homo sapiens, although some aspects (e.g., delayed M3 calcification) are not as derived as that of European populations and people of European origin. This evidence, taken together with the present knowledge of cranial capacity of these and other late Early Pleistocene hominids, supports the view that as early as 0.8 Ma at least one Homo species shared with modern humans a prolonged pattern of maturation.  (+info)

The crystal growth technique--a laboratory evaluation of bond strengths. (3/479)

An ex vivo study was carried out to determine differences in the bond strengths achieved with brackets placed using a crystal growth technique compared with a conventional acid-etch technique. A solution of 37 per cent phosphoric acid was used for acid-etching and a commercially available polyacrylic acid gel, Crystal-lok for crystal growth. A heavily-filled composite resin was used for all samples to bond brackets to healthy premolar teeth extracted for orthodontic purposes. Polycrystalline ceramic and stainless steel brackets were used and tested to both tensile and shear failure using an Instron Universal Testing machine. The tensile and shear bond strengths were recorded in kgF. In view of difficulties experienced with previous authors using different units to describe their findings, the data were subsequently converted to a range of units in order to facilitate direct comparison. The crystal growth technique produced significantly lower bond strengths than the acid-etch technique for ceramic and stainless steel brackets, both in tensile and shear mode. The tensile bond strength for stainless steel brackets with crystal growth was 2.2 kg compared with 6.01 kg for acid-etch, whilst with ceramic brackets the tensile bond strengths were 3.9 kg for crystal growth and 5.55 kg for acid-etch. The mean shear bond strength for stainless steel brackets with crystal growth was 12.61 kg compared with 21.55 kg for acid-etch, whilst with ceramic brackets the shear bond strengths were 7.93 kg with crystal growth compared with 16.55 kg for acid-tech. These bond strengths were below those previously suggested as clinically acceptable.  (+info)

Super pulse CO2 laser for bracket bonding and debonding. (4/479)

A super pulse and a normal pulse CO2 laser were used to carry out enamel etching and bracket debonding in vitro and in vivo. The shear bond strength of the orthodontic brackets attached to laser-etched and conventional chemically-etched extracted premolars was measured. The pulp cavity temperature was also measured using the same laser irradiation conditions as the shear test. Both super pulse and normal pulse CO2 laser etching resulted in a lower shear bond strength (super pulse: 6.9 +/- 3.4 kg, normal pulse: 9.7 +/- 5.2 kg) than that of chemical etching (15.3 +/- 2.8 kg). Furthermore, the super pulse CO2 laser was able to create debonding at 2 watts within a period of less than 4 seconds (2.9 +/- 0.9 seconds). The super pulse, when irradiating the ceramic brackets from above, during debonding showed a 1.4 degrees C temperature increase in the dental pulp at 2 watts and an increase of 2.1 degrees C at 3 watts. While etching, directly irradiating the enamel surface at 3 watts, the dental pulp showed a temperature increase of 3.5 degrees C. These temperature increases were within the physiologically acceptable limits of the pulp. These results indicate that, in orthodontic treatments, super pulse CO2 laser debonding is more useful than laser etching.  (+info)

An ex vivo investigation into the bond strength of orthodontic brackets and adhesive systems. (5/479)

The aim of this study was to compare the shear bond strength of Adhesive Precoated Brackets (APC) with that of two types of uncoated bracket bases, Straight-Wire and Dyna-Lock. Two types of orthodontic adhesives were used, Transbond XT and Right-On. Three different curing times were evaluated with the APC brackets in order to find the best. Adhesive remnants on the enamel surface following debond were evaluated using the Adhesive Remnant Index (Artun and Bergland, 1984). Bond strengths ranged from 11.00 to 22.08 MPa. For both types of brackets Transbond produced a significant increase in bond strength compared to Right-On. The Dyna-Lock/Right-On combination produced the poorest results. APC brackets cured for 40 s had similar bond strengths to uncoated brackets fixed by means of Transbond. Overall, 79 per cent of specimens had less than half the tooth surface covered with adhesive following debond. Significantly more adhesive remained on tooth surfaces following debond of the Straight-Wire/Right-On group than any other bracket/adhesive combination. Bond strengths were higher with light-cured Transbond than with chemically-cured Right-On. When Transbond is used in association with APC brackets a 40-second cure time is recommended.  (+info)

Intra-oral temperature variation over 24 hours. (6/479)

This study aimed to investigate temperature variation at archwire sites adjacent to the maxillary right central incisor and first premolar, its correlation with ambient temperature, and the influence of inter-racial variation. Twenty young adult male subjects were randomly selected (13 Asian, seven Caucasian). Thermocouples were attached to the labial archwire component of custom-made orthodontic retainers at the two intra-oral sites. A third thermocouple measured ambient temperature. A data-logger recorded temperatures at 5-second intervals over a 24-hour period. Temperatures ranged from 5.6 to 58.5 degrees C at the incisor and from 7.9 to 54 degrees C at the premolar, with medians of 34.9 degrees C and 35.6 degrees C, respectively. Ambient temperature correlated poorly with the intra-oral temperatures. The Asian and Caucasian groups had significantly different temperature distributions. On average during the 24-hour period, temperatures at the incisor site were in the range of 33-37 degrees C for 79 per cent of the time, below it for 20 per cent, and above it for only 1 per cent of the time. Corresponding figures for the premolar site were 92, 6, and 2 per cent. At both archwire sites the most frequent temperatures were in the range of 35-36 degrees C. The data presented demonstrate that the temperature at sites on an archwire in situ varies considerably over a 24-hour period and that racial differences may exist. This information should be considered during the manufacture and use of temperature-sensitive orthodontic materials, in particular nickel-titanium archwires and springs.  (+info)

Elastic activator for treatment of open bite. (7/479)

This article presents a modified activator for treatment of open bite cases. The intermaxillary acrylic of the lateral occlusal zones is replaced by elastic rubber tubes. By stimulating orthopaedic gymnastics (chewing gum effect), the elastic activator intrudes upper and lower posterior teeth. A noticeable counterclockwise rotation of the mandible was accomplished by a decrease of the gonial angle. Besides the simple fabrication of the device and uncomplicated replacement of the elastic rubber tubes, treatment can be started even in mixed dentition when affixing plates may be difficult.  (+info)

A laboratory investigation to compare enamel preparation by sandblasting or acid etching prior to bracket bonding. (8/479)

A laboratory investigation to compare the mean shear debonding force and mode of bond failure of metallic brackets bonded to sandblasted and acid-etched enamel is described. The buccal surfaces of 30 extracted human premolars were sandblasted for 5 seconds with 50 mu alumina and the buccal surfaces of a further 30 human premolars were etched with 37 per cent phosphoric acid for 15 seconds. Following storage for 24 hours at 37 degrees C in distilled water, shear debonding force was measured using an Instron Universal Testing Machine with a cross-head speed of 10 mm/minute. Mean shear debonding force was significantly lower for brackets bonded to sandblasted enamel compared to acid etched enamel (P < 0.001). Weibull analysis showed that at a given stress the probability of failure was significantly greater for brackets bonded to sandblasted enamel. Brackets bonded to etched enamel showed a mixed mode of bond failure whereas following sandblasting, failure was adhesive at the enamel/composite interface (P < 0.01).  (+info)

A cusp is an occlusal or incisal eminence on a tooth. Canine teeth, otherwise known as cuspids, each possess a single cusp, while premolars, otherwise known as bicuspids, possess two each. Molars normally possess either four or five cusps. In certain populations the maxillary molars, especially first molars, will possess a fifth cusp situated on the mesiolingual cusp known as the Cusp of Carabelli.. Buccal Cusp- One other variation of the upper first premolar is the Uto-Aztecan upper premolar. It is a bulge on the buccal cusp that is only found in Native American Indians, with highest frequencies of occurrence in Arizona. The name is not a dental term; it comes from a regional linguistic division of Native American Indian language groups..

The first important phase of orthodontic treatment is figuring out what needs to be done. Treatment often involves removing teeth to relieve crowding.
One common goal for treating my patients is to get the canines into Class 1 occlusion, that way I know the overjet is going to be reasonable, in this case, the overbite is normal.. On the right side, the existing space is not where I want it.. But as there is space, it would be silly to extract a tooth to make more space!. The issue is that being so far back, this space will close quickly, without relieving the crowding at the front - which is where we really need the space.. To help with this issue, we need to reinforce anchorage (stop the 6 moving forward).. On the left, there is no space at all! The canine needs to move half a unit distal, so its reasonable to consider an extraction here. The 4 is already filled (and the filling looks terrible!), so this is my choice!. The canine will move 1/2 unit back, and the premolars and molars will come forward to close the space (before de-bond).. ...

Affects facial features - After the loss of alveolar bone, the basal bone present beneath it also begins to melt away. The distance from nose to chin decreases and with the result, the lower part of your face partially collapses. The effects dont end here. The chin rotates forward and upward, and the cheeks become hollow due to loss of tooth support. If there is an extreme loss of bone, then it can make a person more prone to jaw fractures as well.. Loss of self-confidence - When the back teeth that support the height of face are missing, then bite collapse may occur. This can cause the front teeth to be pushed forward. They were actually not designed to chew food or to support facial height but they are designed to hold and incise or tear it. Because the lips of toothless people have sagged, they appear unhappy when their mouths are at rest. Without teeth present, the tongue spreads into space and the face collapses. People lose self-confidence due to these problems.. So, if you are also ...

Dr. Keller responded: TMJ because. Removal of premolars has been shown to cause the jaw joint to move back in the socket and this is a probable pathological position. It is important that your bite be treated at your best functional relationship. You will need to find this position, evaluate stability over adequate time and then probably get retreated so the joints and muscles are not compromised by your bite.
DISCUSSION. A case of CHH is presented here, wherein a 20-year-old female has missing mandibular central incisors, maxillary second molars, and all the third molars. In addition, she had a malformed supernumerary tooth in the mandibular left anterior region. After a thorough literature search, the rarity of such an occurrence prompted the authors to present this case.. When the tooth or teeth are clinically and radiographically absent and there is no history of extraction or traumatic avulsion of teeth, it is termed as agenesis or hypodontia. Literature search reveals that 15% of missing teeth are lower second premolars, 19% upper second premolars, 29% upper lateral incisors, 11% lower first premolars, 3% lower central incisor, and 1% are lower lateral incisor. Hypodontia of second molars and canine is rare (0.7% of missing teeth). Furthermore, 71% of individuals with hypodontia of some other teeth also lacked third molars.7 In the case presented here, bilateral maxillary second molar agenesis ...
INTRODUCTION: Variations in treatment times for serial extraction and late premolar extraction patients may be due to differences in the time needed to flatten the occlusal curves. In this study, we compared tooth tipping and occlusal curves in patients treated by serial extractions or late premolar extractions with untreated controls. METHODS: Mandibular dental casts and cephalometric radiographs were collected from 90 subjects (30 Class I control subjects, 30 patients with serial extractions, and 30 with late premolar extractions) at 3 time points: T0, baseline for the controls and serial extraction patients; T1, after natural drift and preorthodontics for the controls and the serial extraction patients, and pretreatment for the late premolar extraction patients; and T2, after comprehensive orthodontic treatment for the serial extraction and the late premolar extraction groups. The long axes of the central incisor, canine, and first molar to the palatal plane were measured on digitized ...

The parameters for the study group and the control group at the start of the treatment were comparable. There were two values that showed the greatest differences here: the lengths of the treatments and the mean ages at the start of treatment. The length of the treatment, which was slightly longer in the study group (by 5.5 months), can be explained by the different types of treatment used; indeed, extraction treatment generally takes longer than its non-extractive counterpart. The older age in the study group (by almost 1 year), as well as being similar to that considered in other studies, can also be justified in that these patients are monitored until the best moment arrives for them to start treatment [18].. The error found in the method, quantified in our study through Dahlbergs formula, is less than the values obtained in other studies in terms of root measurements [19]. The statistically significant reduction in root length found in the two groups is in agreement with data that have come ...

Medical literature is not unified in the description of the morphology of the mental foramen. Different anatomy and radiology text books give contradicting statements regarding the morphometric characteristics of the mental foramen; thereby depicting variable racial trends. 6 Africans: The mental foramen was observed to exhibit dimorphism; it was 14.89 mm above the lower border of the mandible in males and 14.21 mm in females. Also, it was 16.16 mm below the alveolar ridge in males and 15.66 mm in females. The average size of the long and the short axis of the foramen were 5.66mm and 3.97mm respectively in the male and 4.99 mm and 3.87 mm respectively in the female mandibles.]12These measurements were statistically similar to another study on mandibles from Alagoas state.18 Tanzanians: The mental foramen was frequently located below the apex of the second premolar and between the 2 nd premolar and 1st molar. A significantly less common location was between 1 st and 2 nd premolars and below 1 st ...

Premolar tooth extraction. Close up of the blood-filled cavity left after the extraction of a decayed premolar tooth from a 67-year-old mans upper jaw. Dental caries is the decay and crumbling of the teeth. It is caused by the bacteria in plaque, a substance which covers the surface of unclean teeth. The bacteria break down sugar in the mouth, producing an acid which progressively destroys the teeth. In severe cases such as this, root canal surgery or tooth extraction is needed. For the tooth prior to extraction, see image C029/2193. - Stock Image C029/2194
Diastrophic dysplasia is a recessively inherited osteochondrodysplasia belonging to the group of disorders called the "Finnish Disease Heritage." Abnormalities in DTD seem to be restricted mainly to cartilage and bone. The main features include short-limbed short stature, generalized joint dysplasia, and spinal deformities. Mutations in the sulphate transporter gene DTDST in the long arm of chromosome 5 result in impaired sulphate uptake of the cells and reduced sulphation of the extracellular matrix macromolecules, particularly the proteoglycans. One-third of DTD patients have hypodontia in their permanent dentition; the lower second premolar, upper lateral incisor, and upper second premolar being the teeth most commonly missing. In addition, tooth crown sizes may be reduced. Cleft palate or submucous cleft palate is seen in 30% and 26% of the patients (Karlstedt et al, 1996).

... The causes of these changes can be very varied, but they are invariably linked to the fact that rabbits make throughout their lives teeth of continuous growth. The dentition comprises 28 teeth, in addition to incisors, which can be seen easily, they also have the premolars and molars. Because of the anatomical features of the mouth of the rabbits, the latter are not easy to visualize. The incisors are used to cut the food while the molars and premolars are for grinding food and reduce it to little pieces. The wear of the teeth is made by chewing and by contact between teeth ...
Anchorage control is of great importance in orthodontic treatment. In the treatment of Angle Class II malocclusions, with Class I skeletal relationship, upper anterior crowding or excessive overjet can be treated with either unilateral/bilateral upper premolar extraction or distalization of upper posterior teeth consolidation of the anterior teeth [1]. The extractions create generally bad emotional effects on the patients that fear of dentist is present nearly in all people. Closing of the extraction spaces need extra time in all orthodontic treatment. The researchers have used intaroral distalization mechanics alternatively to the extraction treatment but anchorage loss has shown by the use of a lot of appliances with the significant maxillary incisor proclination and increased in overjet at the end of the distalization. [5, 10, 11].. In the present study, extraction of the impacted premolar will make simpler the all treatment. However, the patient didnt want to the extraction process. We ...
Children in Greater Glasgow and Clyde have even more reasons to smile today as figures reveal that tooth extractions have dropped more than 52% since the millennium.. In 2000-2001, there were 26,355 teeth removed from the mouths of children in the NHSGGC area, dropping to 12,516 by 2015-2016 - the biggest percentage drop of any health board area in Scotland.. While children have teeth pulled out for a number of reasons including trauma to the mouth or for orthodontic reasons, the figures undoubtedly show the success of initiatives aimed at reducing levels of tooth decay.. Karen Murray, NHSGGCs lead for Oral Health said: "These figures are hugely encouraging and great news for children throughout Greater Glasgow and Clyde. Teeth extractions can be very traumatic for children so any reduction - and this is a dramatic one - needs to be applauded.". Back in 2005 the Scottish Dental National Action Plan identified high levels of tooth decay and inequalities in child oral health. The main aim was to ...
This case demonstrates the extraction of a maxillary left first premolar and its replacement with a SHORT® 4.5 x 6.0mm implant using SynthoGraft™, Leukocyte and Platelet Rich Fibrin (LPRF), and collagen membranes. The osteotomy was carefully prepared using latch and hand reamers in 0.5mm increments despite a buccal bone perforation.
Methods: Fifty human mandibular premolar teeth were infected with a mixture of Candida albicans, Pseudomonas aeruginosa, Enterococcus faecalis and Staphylococcus aureus. The specimens were randomly divided into 5 groups with 10 root canals according to the irrigant used. All root canals were instrumented with the ProTaper Universal™ system. Assessment of the antimicrobial action of the irrigant was performed before, during, and after instrumentation. Data were analyzed statistically by Chi-squared test and the Fisher exact test at 5% significance level ...
Our sample showed a vast range of observation periods. This can be explained by the fact that failures, when they happened, often occurred at an early stage after transplantation. In contrary, some teeth had been observed over a long period of time for protocol reasons (consecutive patients). Since only few successful transplantations had observation times shorter than 1 year and by analysing censored data using Kaplan-Meier and log-rank tests with failure as the event, results account for the wide range of observation periods.. Several factors are likely to be associated with survival and success of tooth transplantations. We examined the effect of tooth type, root development stage, recipient area, surgical trauma (surgical skill) and use of intraoperative drugs on success of tooth transplantations.. Premolars with an estimated 10-year success rate of 81.6 % compared favourably to molars with an estimated 10-year success rate of 33.8 %. Thus, while our results for premolars were comparable ...
The purpose of this study was to evaluate and compare enamel micro-crack characteristics of adult patients before and after removal of metal brackets. After the examination with scanning electron microscopy (SEM), 45 extracted human teeth were divided into three groups of equal size. The length and width of the longest enamel micro-crack were measured for all the teeth before and after removal of metal brackets. The changes in the location of the micro-cracks were also evaluated. New enamel micro-cracks were found in 6 of 15 (40 per cent) examined teeth. Greatest changes in the width of enamel micro-cracks after debonding procedure appear in the cervical third of the tooth. On the basis of this result, the dentist must pay extra care and attention to this specific area of enamel during removal of metal brackets in adult patients.. ...
At the age of 12 years it is very unlikely that second premolar is cracked until the tooth is decayed. There is a possibility that the baby tooth was there and it has cracked as your son is not having any pain. It is better you visit your dentist and get the proper clinical examination done. The dentist will take history, do clinical examination and if required take and X-Ray. After that the treatment plan is decided. If the tooth is just broken because of decay then simple restoration will serve the purpose.

A sample of 345 patients provided 6 groups of 60 premolars each in need of endodontic treatment. Groups were classified according to the number of remaining coronal walls before abutment build-up. Within each group, teeth were allocated to one of three subgroups: (A) no post retention; (B) LP; or (C) ES (N = 20). All teeth were protected with a crown. Cox regression analysis revealed that fiber post retention significantly improved tooth survival (p , 0.001). Failure risk was lower in teeth restored with ...

The operation of distribution system with the components in deteriorating condition makes the system reliability worsen. It is important to find the solution for balancing failure cost and maintenance benefits such as down-time and reliability. In this paper, time to replace the components in optimum condition based on constant-interval replacement mode is investigated. The optimal replacement time is mainly depended on components reliability and the cost ration of preventive replacement and failure replacement. In this paper, equipment inspection method and Weibull Analysis is applied to obtain the accurate reliability estimation. Weibull Analysis is applied with constant-interval replacement model to investigate the optimum replacement time for each component considering the different cost ratios. According to the quantitative results, the determination of the optimal replacement time (OPT) can minimize the total downtime and failure cost. Consequently, the reliability of the system is maximized and

A molar tooth is located in the posterior (back) section of the mouth. It is found in most mammals that use their posterior teeth to grind food. Twelve molars are usually present in an adult human, in groups of three.
Multiple dental developmental abnormalities (e.g., dental impaction, partial eruption, oligodontia, enamel hypoplasia, and dentin hypoplasia) in a 10-month-old, female, Tanzanian tropical mixed-breed puppy are reported. Various permanent teeth were involved. These included impacted mandibular canine and first and third premolar teeth; a partially erupted maxillary canine tooth; oligodontia of a mandibular fourth premolar tooth; enamel hypoplasia of the maxillary and mandibular canine teeth, incisors, and premolars; and dentin hypoplasia of the maxillary incisors, maxillary premolars, and mandibular premolars. The puppy had clinical canine distemper at the age of two months and had no history of any other systemic nor generalized infection prior to the time when the dental abnormalities were observed.
Objectives: The objective was to assess the shear bond strength (SBS) of composite resins on stainless steel brackets immediately bonded to previously bleached teeth with 35% hydrogen peroxide and to compare the neutralization effect of various antioxidant agents on the bond strength after bleaching. Materials and Methods: One hundred sound human maxillary premolars were used for the study. Teeth were divided into 5 groups (n = 20); Group 1 (control), Group 2 (bleach treatment), Group 3 (sodium ascorbate treatment), Group 4 (tocopherol acetate treatment), and Group 5 (retinol acetate treatment). Teeth in Group 3, 4, and 5 were treated as in Group 2, but after that and before bleaching received treatment with sodium ascorbate, tocopherol acetate, and retinol acetate, respectively. Subsequently, teeth were bonded with stainless steel brackets (Ormco) using 3M Transbond XT. After 24 h, each specimen was loaded into a universal testing machine to determine the SBS at debonding. The data were exposed ...
The Boxer puppies are born without any teeth. Although, they do exist, but are usually disappeared within the gums at the time of birth. When your boxer puppy turns of 6 weeks, the teeth start gradually appearing. Those are the milk teeth. The processes starts with 6 incisors appearing on top and bottom each and the total comes as twelve. There are also premolars on the sides of the incisors, 3 on each side, on both top and bottom. Slowly, the puppy reaches obtaining a total of twenty eight teeth. When your puppy is 5-6 months old, the milk teeth are vanished and canines start to grow. If your puppy doesnt have this stage by the age of 7 months, then a proper veterinarian must be consulted.. ...

A 46-year-old male patient presented with concerns about the esthetics of his maxillary anterior dentition. His chief complaint was the diastemata between both central incisors and between the right central and canine. Both of his maxillary lateral incisors had been congenitally missing and were substituted by moving his canines and premolars orthodontically at a young age. However, spaces returned between his anterior teeth following orthodontic therapy. Despite the attempts of minimal enameloplasty, the transformation of the canines to lateral incisors has remained unsatisfactory. The patient refused further orthodontic therapy to close his multiple diastema. As another option, we utilized minimally invasive restorative cosmetic therapy which would conserve maximum tooth structure. The treatment plan comprised six veneers covering the maxillary central incisors, the canines, and the first premolars. This Minimum Prep Veneer therapy provided the Esthetic Care the patient desired.. ...
Kovanaze™ is the first needle free anesthetic option that I know of. Kovanaze™ was approved in the summer of 2016 by the FDA for use as a dental anesthetic and became available for purchase towards the end of the year. Kovanaze™ is a combination of the anesthetic tetracaine and oxymetazoline. This solution is sprayed up the nostril and provides anesthesia from the premolars to central incisor on the same side. Second premolars have a success rate around 64% while the first premolar through central incisor have a success rate of 96%. For major anterior work, such as veneers, this is a game changer. I know that I personally hate giving injections for the maxillary anterior teeth due to the sensitivity of the tissues in this area, especially around the centrals. Going from multiple painful injections to several painless nasal sprays makes these procedures far easier and essentially painless for patients.. The big downside at this point is cost. As of the time of this writing it costs ...

About the incidence of ARR in patients treated with aligners, there is only few reported evidence [3, 16]. Therefore, this is the first study, investigating the incidence and severity of ARR in patients with a fulfilled aligner therapy.. ARR of upper incisors during treatment with aligners in a 25-year-old patient were described in a case report [16]. Barbagallo et al. [17] investigated the effects of removable thermoplastic appliances (TA) vs. light or heavy forces with fixed appliances in premolars, which were afterwards extracted. They found that teeth, which experienced orthodontic tooth movement, had significantly more RR than the control teeth. TAs had similar RR as light (25 g) orthodontic forces [17]. But the treatment duration was only eight weeks and only sagittal movements were conducted. In the animal experimental study of Sombuntham et al. [18] clear plastic appliances were inserted but bonded to the residual dentition in rats. Their findings indicated initial superficial RR similar ...
Orthodontic treatment for patients with uni- or bilateral congenitally missing lateral incisors is a challenge to effective treatment planning. The two major alternatives, orthodontic space closure or space opening for prosthetic replacements, can both compromise aesthetics, periodontal health, and function.. The aim of this retrospective study was to examine treated patients who had congenitally missing lateral incisors and to compare their opinion of the aesthetic result with the dentists opinions of occlusal function and periodontal health. In this sample, 50 patients were identified. Thirty had been treated with orthodontic space closure, and 20 by space opening and a prosthesis (porcelain bonded to gold and resin bonded bridges). The patients opinion of the aesthetic result was evaluated using the Eastman Esthetic Index questionnaire and during a structured interview. The functional status, dental contact patterns, periodontal condition, and quality of the prosthetic replacement was ...

The aim of this study was to determine the predominant supragingival cultivable bacterial flora in Chinese individuals, using the experimental gingivitis model. A total of 11 healthy dental students, mean age 22.5 years (range 20-25) were recruited. All were provided with once-a-week dental prophylaxis and oral hygiene reinforcement for 3 weeks to ensure gingival health. In the fourth week, after prophylaxis, the participants entered a 14- day period without any plaque control. A plaque sample was collected at days 1, 3, 7 and 14 from the buccal surface of the upper right canine, second premolar, first premolar and first molar, respectively. Each sample was then dispensed in tryptic soy-broth transport medium and grown anaerobically to obtain pure cultures, which were subsequently identified. Results showed that Gram-positive cocci and rods were the predominent cultivatable species (51- 61%) in the samples throughout the 14-day period; with time there was a decreasing percentage of cocci and an ...
This paper is a description based on the Sinanthropus materials including5 teeth and two fragments of humerus and tibia recovered since the restorationof the Choukoutien excavation in 1949.The teeth of Sinanthropus are much bigger than those of modern man.Theleft medial upper incisor bears well-developed basal tubercle on the lingualsurface.The upper first and second premolars are robust in size and theirchewing surfaces are covered with wrinkles of special patterns.The crowns ofthe first and second lower molars are characterized by their lowness in relationto their lengths and breadths.Pronounced cingulum is present on the buccalsurface of the crown.The humeral shaft is almost identical with that of modern man.Thetibial shaft is slender and its anterior border is blunt.The walls of the tibiaare extraordinarily thick and its medullary cavity is very narrow.The results of the study of Sinanthropus pekinensis by the present authorsand others clearly show that the upper extremity bones of Sinanthropus
The purpose of this study was to determine the amount of space available distal to the most posterior tooth in the mandibular arch for complete arch distalization. Methods: CBCT scans from 146 (110 after exclusion criteria) patients were rendered using InVivo DentalTM Software. A 1:1 ratio panoramic image was reconstructed from each scan. A horizontal measurement, parallel to the functional occlusal plane, was recorded from the distal height of contour of the most posterior tooth to the ascending ramus. The advantages of using a CBCT reconstruction are: (1) A traditional panoramic radiograph uses an arbitrary focal trough; (2) There is inherent error and distortion due to the magnification in the traditional panoramic radiograph; (3) The magnification from traditional radiographs makes measurements very unreliable; (4) Contrast is improved with CBCT and blurring and overlapping is eliminated. Results: There was an average of 7.27 mm [7.24 mm (left) and 7.29 mm (right)] distal to lower second ...
