Maxillary first molar usually exhibits a radicular anatomy of three roots and three or four canals. However, different anatomic variations like extra number of roots and canals are possible. For a successful treatment, clinicians must have well equipment and a thorough knowledge of the external and internal anatomy of teeth and its variation. Using of CBCT may help to locate extra canals by giving a chance to clinicians to see the root canal anatomy in 3-D view. The aim of this study was to present a case report about a diagnosis and treatment in maxillary first molar with three roots and five canals. It is concluded that the diagnosing and the treatment of unusual cases are key factors for successful endodontic treatment of these teeth.

Several articles have used cone beam computed tomography (CBCT) to study the morphology of the maxillary molars and to ascertain its ability to visualize the second mesiobuccal canal (MB2); however, its geometric location has not been examined in depth. The aim of this study was to describe in vivo the prevalence and location of the MB2 in the mesiobuccal root of the first maxillary molar (1MM) and the second maxillary molar (2MM) through CBCT imaging. Five hundred fifty CBCT images of the 1MM and 550 of the 2MM were analyzed. To detect the MB2 canal, the observation and measurements were done 1 mm apically to the pulpal floor to standardize the methodology. The geometric location of the central point of the MB2 canal (PMB2) was measured in relation to the central point of the mesiobuccal canal (PMB1) and in relation to the line projected between the PMB1 and the central point of the palatal canals (PP). The data were analyzed using descriptive statistics, with a value of P | 0.05 being statistically

OBJECTIVES: The aim was to investigate associations between factors and the incidence of erosive wear in lower first molars and upper incisors, and to investigate whether these associations differ between these locations. METHODS: The study sample of this 3-year longitudinal study consisted of 572 children (mean age 11.9 years, SD=0.9). The permanent dentition was examined for erosive wear according to a modified Lussi-index (1996). Information on biological and behavioural factors was gathered by clinical examinations (at baseline, after 1.5 and 3 years) and by questionnaires (every six months). RESULTS: The incidence of erosive wear in upper incisors over 3 years was 22.2%, for lower first molars the incidence was 14.8%. Multivariate logistic regression analysis showed that carbonated soft drink (OR=1.04) and tooth grinding (OR=2.93) were positively associated with the incidence of erosive wear in upper incisors and milk (OR=0.95) and yoghurt products (OR=0.88) were negatively associated. The ...

TY - JOUR. T1 - Eruption process of the second molar. AU - Tsai, Hung Huey. PY - 2000. Y1 - 2000. N2 - The second molar is located at the distal of the first molar, and we must beaware of its stage of development when we plan to move the first molar distally Few researchers have investigated the development of second molars. The purpose of this study was to observe the eruption process of the maxillary and mandibular second molars by using 238 panoramic radiographs. The developmental stages of the second molar were divided into four stages: the whole crown calcified = stage 1 ; beginning root formation = stage 2; initial formation of the radicular bifurcation = stage 3; and the root length is equal to the crown height = stage 4. The mesiodistal crown width of the first and second molars, axial inclination and eruption rate of the second molar, and the space available for emergence of the second molar at each stage were measured, and the statistical analysis was made to assess the developmental ...

Day-14 lower incisors and day-18 first lower molars of mouse embryos produced in vitro transforming activities for non- confluent NRK cells co-cultured in agar, and mitogenic activities for exponentially growing NRK and BHK cells. The patterns of distribution of TGF beta 1 and EGF receptor, both known to regulate cell proliferation, differentiation and transformation in vitro and suspected to play important roles in developmental processes, were studied during mouse odontogenesis by means of indirect immunofluorescence on fixed or frozen fixed sections. TGF beta 1 epitopes were detected in the stellate reticulum of day-13 to day-16 incisors and of molars from day-17 onwards. Dental mesenchyme of day-14 incisors and postnatal molars, and peridental mesenchyme of bud and cap stage molars and incisors were also stained by TGF beta 1 antibodies. EGF receptor was localized in the enamel organs of incisors and molars; the inner dental epithelium and later the outer dental epithelium rapidly became ...

Introduction: The management and long-term retention of molars exhibiting furcation invasion have always been a challenge in dentistry. Latest innovations in dental sciences and higher patients expectations have led to more conservative treatment approaches in saving the teeth with hopeless periodontal prognosis. When periodontal disease affects the furcation area of tooth, the chance of its exfoliation increase considerably. Here, authors have sought to discuss a comprehensive review of literature with case report for the management of decayed mandibular first molars (with furcation invasion) using bicuspidization procedure. Case Report: The furcation defect (in mandibular first molars) was clinically detected in a middle aged male, which was converted into two bicuspids by intentional bisection procedures. The definitive treatment included restoration with double crowns. Bicuspidization procedure with double metal crowns truly yielded a satisfactory result. Discussion: The treatment of ...

Imagine a time when it was considered revolutionary to hear a concert down a telephone line! This occurred in 1892 at the 13th British Dental Association (BDA) conference in Manchester, courtesy of the National Telephone Company.. I have this information on good authority from the BDA Museum which had a stand at the 2014 BDA conference, also in Manchester. Some 200 delegates went to the 1892 meeting. Apparently one of the highlights was a discussion about the extraction of first permanent molars. The majority of delegates concluded that extraction should be avoided if possible unless the teeth were unsaveable.. How interesting that 122 years later there is a Saving Teeth Awareness Campaign which highlights how important it is for teeth to be saved: www.savingteeth.co.uk. When it comes to technology, however, times have certainly changed. At the 2014 meeting the range of equipment and technology was staggering.

The hippopotamus, a semiaquatic mammal native to Africa, eats mostly grasses and other vegetation, but occasionally scavenges for meat. The hippo uses its molars, located in the back of the mouth, to grind these foods. The molars are crucial to consuming the diet; a hippo whose molars are too worn will starve.

A Single wires should always be used for interfragmentary wiring. In this case a single wire was twisted double before it was used for the original fracture repair. Twisting a wire on itself does not improve the strength of the wire and the multfilament nature thereof increases the surface area with resultant increased bacterial adhesion. There is secondary infection with bone loss in the fracture line surrounding the distal (caudal) root of the mandibular molar (409) tooth. Furthermore, there appears to be a fragment of non-vital bone (sequestrum) ventral to the distal root of the 409 ...

Yesterday was another terrible day at the vet and today is one of our worst recovery days ever.. Gari had the first molar on his lower right removed. The tooth was dead and decaying inside the bone. In fact, there was a tunnel through the bone from the first molar to the incisor he had taken out last time. This kept the incisor hole from healing up correctly. Instead the whole thing is full of old food and debris. They couldnt close it this time because in order to clean it out completely, he would need to be intubated, which is a procedure we have not yet faced.. The second molar is also dead and will need to be extraced. That wasnt done this time because he was already under for a long time and had enough trauma to his mouth for a lifetime, let alone a single vet visit.. The worst thing is that he is unable to stand or walk or even sit up today. Yesterday when we left the vet, he was able to walk fairly well, but he deteriorated during the car drive home. We basically had to lift and drag ...

Several studies [15],[23],[29],[30] evaluated the efficacy of the Pendulum appliance, reporting data relative to dentoalveolar and skeletal changes, but few studies [7],[14],[31] described molar distalization in the presence of fully erupted second molar. Segmented and Quad Pendulums were previously described by Kinzinger et al. in a case report study [21] and differed from most distalizing devices since TMA wires acted directly on second molars, without being distalized by a force applied on the first molar. Appliance design was based on the concepts of Gianelly [17] and Jeckel and Rakosi [18]; according to them, when the second molars have erupted, the distalization of the molars should be done in stages, first, the second molars and then the first molars.. No significant difference was found in molar distalization between the two appliances. The second molar distalized 3.8 mm in the SP and 3.2 mm in the QP, and the first molar distalized 4 and 3.5 mm, respectively, between T1 and T2. ...

Fusion is a rare occurrence in molar teeth. The purpose of this rare case presentation is to describe the nonsurgical endodontic treatment of maxillary molar. A 28-year-old patient was referred for endodontic treatment of her chronic apical abscess of right maxillary second molar. In the clinical examination, a sinus tract adjacent to involved tooth and a small crown of supernumerary tooth fused to the buccal surface of the molar at gingival margin was observed. Endodontic treatment was decided for the involved molar for functional reason. Recall examination, a year after completion of endodontic and restorative treatments, showed the tooth was clinically asymptomatic and there was no radiographic lucency around the apical region.. ...

Dentists are constantly faced with the challenge of regaining space after the permanent maxillary first molars have mesialized due to premature extraction or exfoliation of the deciduous second molars. With this event, a Class II molar relationship may result.. When gaining space or distal movement of the permanent maxillary first molars is needed, one of the many appliances that can be used is the pendulum appliance.. It consists of an acrylic Nance button for anchorage. Wires are extended from the acrylic and bonded to the first and second premolars or first and second deciduous molars for stability. Helical springs made of 0.032 TMA wire extends from the distal aspect of the acrylic and are inserted to the lingual sheath of the bands on the permanent maxillary first molars. When activated, it delivers a force of 200-250 grams per side and produce a swinging arc motion, hence the name Pendulum.. Reference ...

Age estimation is required for forensic cases such as minors without documentation and age disputed asylum seekers. Cervical vertebral maturation (CVM) is a potential method to estimate age, particularly when third molars are mature or absent. The aim of this study was to assess the accuracy of estimating age by maturation of the cervical vertebra, the mandibular second (M2) and third (M3) molars in a group of males. The sample consisted of lateral cephalograms of 60 boys from the Bolton-Brush online collection and 53 from Burlington online collection aged 10 to 15 years. CVM age was calculated from age category and mean age and transition age of CVM stages, calculated from raw data of 69 boys (aged 9 to 15 years) in Lamparski (1972). Dental age was calculated using mandibular second and third molar stages from Liversidge (2009). The mean difference and absolute mean difference between CVM age and dental ages and chronological ages was calculated. CVM and molar tooth stage assessment reliability ...

The age of the ox or cow is told chiefly by the teeth and less perfectly by the horns. The temporary teeth are in part through at birth, and all the incisors are through in twenty days; the first, second and third pairs of temporary molars are through in thirty days; the teeth have grown large enough to touch each other by the sixth month; they gradually wear and fall in eighteen months; the fourth permanent molars are through at the fourth month; the fifth at the fifteenth; the sixth at two years. The temporary teeth begin to fall at twenty-one months, and are entirely replaced by the thirtyninth to the forty-fifth month. The development is quite complete at from five to six years. At that time the border of the incisors has been worn away a little below the level of the grinders. At six years, are beginning to wear, and are on a level with the incisors. At eight years, the wear of the first grinders is very apparent. At ten or eleven years, used surfaces of the teeth begin to bear a square ...

At this early stage it may be appropriate for the patient to be reviewed by an orthodontist to assess the growth and development. Once this is completed a treatment plan can be presented.. Treatment of minor cases of MIH may only require the teeth to be restored (filled) with a composite resin (tooth coloured) restoration. In moderate to severe cases preformed stainless steel crowns are often placed. In some cases with severe MIH the first permanent molars may be extracted to allow other molars to erupt into their position.. If the front teeth are affected they may require some cosmetic improvements. This may involve external bleaching followed by masking the defect with a tooth coloured filling material. This treatment is often delayed until growth completion unless there are specific aesthetic concerns expressed by the patient or parents.. Treatment is often carried out in the clinic with local anaesthetic. In cases where the child is anxious or the teeth are very sensitive, relative analgesia ...

Sealants are quick and easy tooth-colored plastic coated resin coatings designed to fill little grooves in your teeth to prohibit bacteria buildup. The process is quite simple. Your dentist will clean your teeth, then apply a solution that will allow the sealant to stick tightly to the tooth. The first dental sealant to be placed is usually on the fissure of the first permanent molar tooth, once the chewing surface of the tooth has erupted completely beyond the gum. Your dentist will then paint the sealant on in a liquid form in hardens in just about a minute, and thats it! Best of all, studies have shown that sealants can reduce decay up to 70% and can last nearly a decade! ...

I bought a nice gaming PC for my 2 operative rooms, downloaded the software, watched some videos, and started scanning. Its really easy to use, my crowns fit better with fewer adjustments, and they cost less because they are made model-less and without impression materials. I will start to see a return on investment in less than 2 years and it makes my work more fun, and I can deliver better results. Armen puts on a 2 day course which is very helpful to refine your technique. Start with watching the videos, scan your employees, and then use it on patients. I considered buying an iTero Element 2 and Im so glad I didnt. The Medit is smaller, as good or better, and it costs ~$25,000 less ...

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

Even though the teeth were isolated, previous researchers were able to reconstruct their order and location in the male or female Neanderthals mouth. Frayer said researchers have not recovered the mandible to look for evidence of periodontal disease, but the scratches and grooves on the teeth indicate they were likely causing irritation and discomfort for some time for this individual.. They found the premolar and M3 molar were pushed out of their normal positions. Associated with that, they found six toothpick grooves among those two teeth and the two molars farther behind them.. The scratches indicate this individual was pushing something into his or her mouth to get at that twisted premolar, Frayer said.. The features of the premolar and third molar are associated with several kinds of dental manipulations, he said. Mostly because the chips of the teeth were on the tongue side of the teeth and at different angles, the researchers ruled out that something happened to the teeth after the ...

Your horses top jaw is wider than the bottom. When he grazes in the wild his jaw moves from side-to-side as he munches - for up to 18h a day! What a life :) This helps keep the wear on the teeth even. But when the horse eats hard feed (ie pellets, grain, etc) the jaw moves much less, which means the teeth do not wear evenly. The stabled horse is also far less likely to spend all day grazing. This combination of less grazing and less jaw movement causes very sharp points appear on the outside of the upper molars and the inside of the lower ones. To help with this we float or rasp the teeth -- usually needs to be done about once/year, but they should be checked every six months, just in case. This basically files the sharp points off so your horse can be comfortable ...
