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 ...

Abstract Joubert syndrome (JS) is a rare autosomal recessive neurodevelopmental disorder that usually diagnosed late in pregnancy or postnatally based on pathognomonic midbrain–hindbrain malformation seen magnetic resonance imaging brain, which consists of the hypoplasia cerebellar vermis, thickened superior peduncles, and deepened interpeduncular fossa described as molar tooth sign. The recurr...

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...

most mandibular second molars have one and two canals in distal and mesial roots, respectively. this report represents four cases of mandibular second molars with a single mesial and two distal root canals with two different canal configurations. after access cavity preparation, two teeth had one distal and two mesial orifices, whereas in the two other teeth one mesial and two distal orifices w...

The study investigates the gender predictability of permanent maxillary first molar teeth. Mesio distal width of 30 permanent maxillary first molar teeth from casts of 15 male and 15 female patients between the age group of 1725 were measured. Results showed that permanent maxillary first molar tooth exhibited sexual dimorphism but accuracy of gender predictability was only moderate.

Ectopically erupted tooth is a rare disease, indicating that a tooth erupts into regions other than the oral cavity. We present a case of an ectopic maxillary third molar tooth in the external acoustic meatus, and discuss the diagnosis and treatment of this entity.
