PURPOSE The aim of this study was to describe an experimental surgical technique to be used in the evaluation of bone grafts in rabbits. METHODS The operative technique was performed in jaws, with external approach from the labial commissure to the last molar tooth. An incision about 1cm extended forward to the alveolar ridge, followed by a exposing the cervical region of the alveolar bone an...

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...

Tooth impaction is a pathological situation where a tooth fails to attain its normal functional position. Impacted third molars are commonly encountered in routine dental practice. The impaction rate is higher for third molars when compared with other teeth. The mandibular third molar impaction is said to be due to the inadequate space between the distal of the second mandibular molar and the a...

In this paper, a new method for individual tooth segmentation was proposed. The proposed method is composed of enhancement and extraction of boundary and seed of watershed algorithm using trisection areas by morphological characteristic of teeth. The watershed algorithm is one of the conventional methods for tooth segmentation; however, the method has some problems. First, molar region detectio...

WNT10A is a signaling molecule involved in tooth development, and WNT10A defects are associated with tooth agenesis. We characterized Wnt10a null mice generated by the knockout mouse project (KOMP) and six families with WNT10A mutations, including a novel p.Arg104Cys defect, in the absence of EDA,EDAR, or EDARADD variations. Wnt10a null mice exhibited supernumerary mandibular fourth molars, and...

Introduction:There are conflicting reports on the effects of surgical removal of impacted mandibular third molars on the periodontium of the adjacent teeth. The aim of this study was to compare the condition of the periodontium six months after extraction of impacted mandibular third molars with baseline values. Methods: Fifty patients with mesioangular impacted mandibular third molarsparticipa...

Background : The aim of the current study is to examine the effect of systemically administered BP-Pamidronate, on Orthodontic Tooth Movement (OTM) along with osteoclastic quantification in New Zealand white rabbits. Materials & Methods : Twenty rabbits used in the study, were equally divided into 2 groups ; Group-1 as Control & Group-2 as Experimental. A sentalloy NITI closed coil spring (GAC ...

PURPOSE The aim of this study was to evaluate the repeatability of the digitizing of silicon rubber impressions of abutment teeth by using a white light scanner and compare differences in repeatability between different abutment teeth types. MATERIALS AND METHODS Silicon rubber impressions of a canine, premolar, and molar tooth were each digitized 8 times using a white light scanner, and 3D s...

INTRODUCTION Gossypiboma (foreign body granuloma) in the tooth socket as a complication of tooth removal is rare. Several cases of gossypiboma have been reported after orthopedic, abdominal, otorhinolaryngology, or plastic surgery, but there has been only one reported case after oral surgery. CASE PRESENTATION A 42-year-old Caucasian German-speaking Swiss woman applied to our clinic for remov...

Diş hekimleri, klinikte diş tedavileri sırasında dişin anatomik yapısıyla ilgili çeşitli varyasyonlarla karşılaşabilirler. Süpernümerer ; en sık görülen varyasyonlardan biri olmasına rağmen, azı dişlerinde fazla kök bulunması varyasyonunun ilginç bir örneğidir. Mandibular dişleri genellikle 2 ayrı köke( mesial ve distal) sahiptir. Çok nadiren ilave üçüncü (süpernümerer kök) görülür.Ana distal k...
