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.. Buccal-The side of a tooth that is adjacent to (or the direction towards) the inside of the cheek, as opposed to lingual or palatal, which refer to the side of a tooth adjacent to (or the direction towards) the tongue or palate, respectively.

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 ...
After initial sedation with the ketamine and xylazine cocktail previously described, the dogs were intubated and administered 1% to 1.5% isoflurane in oxygen at a rate of 1 L per minute. Vital signs were monitored throughout. Local anesthetic (2% lidocaine with 1:100,000 epinephrine) was administered at the surgical sites via regional infiltration and an inferior alveolar block. Both mandibular second premolars were sectioned, elevated, and extracted. On the experimental side, chosen using an electronically generated random number table, a full-thickness mucoperiosteal flap was elevated from the distal aspect of the third premolar to the mesial aspect of the first premolar. A vertical releasing incision was made at the mesial limit of the flap that went past the keratinized gingiva and into the level of the buccal mucosa ( Fig 1 , B ). The tissue was reapproximated with simple interrupted 4-0 vicryl resorbable sutures. A 12-fluted carbide bur was used to remove calculus and debris from the teeth ...
Background and aim To perform a systematic review of anatomical studies using cone beam computed tomography (CBCT) to assess the influence of demographic factors (age, gender and geographic region) on the prevalence of C-shaped canal anatomy in maxillary molars, mandibular premolars and molars. Data sources A search was conducted between May and August 2018 in four electronic databases and five peer-reviewed journals. The authors of included articles were also contacted for additional studies and the bibliographic references hand-searched. Study eligibility criteria, participants and interventions The research protocol was previously registered in the International Prospective Register of Ongoing Systematic Reviews (CRD42018095201) and included defined inclusion/exclusion criteria. Prevalence studies on C-shaped canal anatomy in maxillary molars, mandibular premolars and molars were searched.

A total of 443 hydroxyapatite-coated cylindrical implants were placed into the posterior mandibles of consenting patients from July 1985 through December 1991. Implants were placed into ridges that had sufficient bone volume. Implants were also placed in ridges with thin bone, grafted bone, or immediate extraction sites, which occasionally resulted in increased morbidity. All were followed yearly with clinical and radiographic examinations. Life table analyses were performed using SAS software. Ten-year cumulative survival and nonmorbid (based on bone loss criteria) rates were determined for the four posterior tooth locations and for all posterior locations combined. Cumulative survival for implants was 0.858 ± 0.056 in the first premolar region, 0.833 ± 0.041 for the second premolar region, 0.785 ± 0.041 for the first molar region, and 0.718 ± 0.064 for the second molar region. When all posterior mandibular locations were taken together, the cumulative survival was 0.793 ± 0.025. ...

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.
The ideal built-in tip and torque values of the straight wire appliance reduce the need for wire bending and hence reduce chair time. The vertical position of the bracket on the tooth surface can alter the torque exerted on the tooth. This is a result of the altered surface curvature observed at each vertical position. To further clarify the role of vertical bracket positioning on the applied torque and the resultant stresses in the periodontal ligament (PDL), we designed a mandibular first premolar using finite element modeling. Cone beam computed tomography of 52 patients (83 lower first premolars) was selected to be included in the study. Curvature was measured for points along the labial surface with increasing distances (0.5 mm increments) from the cusp tip by calculating the angle between tangents drawn from these points and the axis joining the cusp tip and the root apex. The mean values for each distance were calculated, and a finite element model was designed incorporating these mean values.
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 ...
0027] The process for preparing the water-soluble extract has been disclosed in U.S. Pat. No. 7,078,063 B2 and includes the steps of: [0028] (a) subjecting a plant material of a plant of Solanum genus to an extraction treatment using an acidic aqueous solution with a pH value of 3˜5, such that an aqueous solution is obtained; [0029] (b) adjusting the pH value of the aqueous solution obtained in step (a) to pH 8˜10 with a base, such that a precipitate is formed; [0030] (c) washing the precipitate formed in step (b) with water, followed by drying, such that a dried product is obtained; [0031] (d) admixing the dried product obtained in step (c) with chloroform, followed by addition of a suitable amount of a 100% alcohol, such that a chloroform-alcohol mixture is formed; [0032] (e) mixing the chloroform-alcohol mixture formed in step (d) with a water/alcohol solution having a predetermined water:alcohol ratio, such that mixture containing a chloroform-based layer and a non-chloroform-based layer ...
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 ...

title: Genetic analysis of non-syndromic familial multiple supernumerary premolars, doi: 10.1080/00016357.2017.1312515, category: Article
This study was a comparative evaluation of the bending resistance of metallic and resorbable plates and screws in a mandibular body fracture model. Forty polyurethane synthetic hemimandibles were used; a vertical linear cut was made between the second and first premolars. These 40 hemimandibles were divided into four groups of 10 and were fixed with titanium plates and screws or resorbable plates and screws, with monocortical screws in the upper sector and bicortical screws in the lower sector. Bending resistance tests were done on a universal testing machine with a linear displacement speed of 1 mm/min, a cell load of 500 N, and a load cell on the lower central incisor or on the lower second premolar. Results were analyzed using the Students t-test, with the significance level set at 5%. No statistically significant differences were observed between the groups studied, either in the analysis of the osteosynthesis materials or related to the load-bearing points. The variables of displacement ...
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
A lower P2 is not hard to distinguish from a lower M3 (Fig.1). Actually these differences are caricatures of differences between other lower premolars and molars. About seventy years ago Gromova noted them : develoment of the hypostylid (short, wide and flattened on premolars, elongated and narrow on molars), relative anterior and posterior occlusal widths (Fig.2). A third difference is in the angle between occlusal surface and dental crown : on premolars the occlusal surface is close to (...)

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 dental pathology is very common in rabbits. 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 ...
The aim of this study was to present a temporary anchorage device with intraosseous screw for unilateral molar distalization to make a space for the impacted premolar and to found well balanced occlusion in a case. A 13-year-old male who have an impacted premolar is presented with skeletal Class I and dental Class 2 relationship. The screw was placed and immediately loaded to distalize the left upper first and second molar. The average distalization time to achieve an overcorrected Class I molar relationship was 3.6 months. There was no change in overjet, overbite, or mandibular plane angle measurements. Mild protrusion (0.5 mm) of the upper left central incisor was also recorded. Immediately loaded intraosseous screw-supported anchorage unit was successful in achieving sufficient unilateral molar distalization without anchorage loss. This treatment procedure was an alternative treatment to the extraction therapy.
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.
OBJECTIVES:. Implant placement immediately after tooth extraction is often accompanied by resorption of surrounding tissues. A clinical technique was developed where the buccal portion of the root is retained to preserve the periodontal ligament and bundle bone. This technique is based on animal studies showing the potential to preserve the facial tissues utilizing this approach. The purpose of this study was to gain more insight regarding the safety of the technique with regard to biological and implant-related long-term complications and to observe the clinical appearance of the peri-implant tissues. Another objective was to evaluate volumetric changes of the affected facial contours in long-term and the esthetic outcomes.. MATERIAL AND METHODS:. This study is a retrospective case series of 10 consecutive patients with implant replacement between the maxillary first premolars. Impressions were made prior to extraction (t1) and 5 years post-implant placement (t2). 3D-surface scans of the casts ...
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 ...
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.
