This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second premolar tooth. The clinical and radiographical evaluation revealed an external apical resorption in the mesial root of the maxillary first mo...

Aim : The aim of this study is to evaluate the angulation of impacted mandibular third molars and also to evaluate the most common sex affected . Objective: To determine which angulation is more common in impaction To determine the prevalence of mandibular third molar impaction based on gender Materials and Methodology: The study was conducted on 110 subjects which consists of 58 males and 52 f...

A case is presented which demonstrates the incomplete transposition of a posterior tooth. In this case, the path of eruption of an abnormally angulated developing mandibular second premolar was diverted distally following the extraction of the adjacent first

OBJECTIVE To compare the interproximal soft tissue dimensions adjacent to single implant restorations in the premolar-molar position with those adjacent to the contra-lateral natural teeth. MATERIAL AND METHODS Twenty-five patients with a single-tooth implant in premolar-molar position and healthy contra-lateral teeth were enrolled in this retrospective cross-sectional study. The reason for t...

Gingival clefts adjacent to the maxillary canine teeth present a challenge to the veterinary dental surgeon. Periodontal disease results in loss of attached gingiva resulting in periodontal pockets and/or gingival recession. Recession can extend apically toward or beyond the mucogingival margin resulting in clinical exposure of the root surface and subsequent cleft formation. A lateral sliding ...

If a posterior tooth has been lost and is not restored immediately, the patient may subsequently experience a variety of problems. The adjacent teeth tend to tilt and rotate, and the opposing tooth may overerupt. Available options to restore occlusion include elective root canal treatment with invasive tooth reduction, surgical impaction or orthodontic therapy requiring extraoral headgear or fu...

INTRODUCTION A case report showing the removal of a supernumerary tooth from the nasal cavity by means of an endoscopic approach is presented. MATERIALS AND METHODS A 9-year-old healthy child presented to our department because of the right central incisor which appeared clinically rotated. The observation of orthopantomography revealed the presence of a supernumerary tooth in the anterior ma...

Reptiles and fish have robust regenerative powers for tooth renewal. However, extant mammals can either renew their teeth one time (diphyodont dentition) or not at all (monophyodont dentition). Humans replace their milk teeth with permanent teeth and then lose their ability for tooth renewal. Here, we study tooth renewal in a crocodilian model, the American alligator, which has well-organized t...

An integrated experimental and theoretical approach is proposed for the evaluation of stress within a natural tooth during bruxing. A physical model was developed that used strain gauges bonded to the buccal and lingual heights of contour of extracted, intact maxillary premolar teeth for the validation of a two-dimensional finite element model of a natural, intact maxillary premolar tooth. Resu...

The purpose of these case reports is to introduce an innovative orthodontic appliance to effect forced eruption. This device is useful when attempting to erupt teeth in the esthetic zone with minimal effect on adjacent teeth. It is especially indicated for adjacent teeth with esthetic restorations. The appliance is easy to fabricate, cost-effective and very useful in forced eruption efforts for...
