OBJECTIVE The aim of this study was to identify the prevalence of pathological changes in the pericoronal tissue of asymptomatic impacted lower third molars and to assess the correlation between pathological changes and patient demographic, radiographic and morphological characteristics. STUDY DESIGN Follicles associated with fully impacted lower third molars were submitted for histological e...

INTRODUCTION The first aim of the present study was to analyze if any correlation exists between the post-graduate's and the tutor's difficulty evaluation of the same tooth to be extracted. Secondly, the study aimed to verify whether, and possibly which, anatomical/topographic characteristics of the impacted lower third molar influence the post-graduate's difficulty evaluation. Thirdly, patient...

Ectopic teeth have been rarely described in non-dental and non-oral localizations. Ectopic tooth eruption in maxillary sinus usually runs across incidentally during routine radiological or clinical evaluation because it is generally asymptomatic. If it occurs symptomaticaly; the findings like purulent rhinorrhoea, facial pain, headache, swelling, epistaxis and epiphora can be seen. It is often ...

PATIENTS AND METHODS A retrospective study of 4,995 lower third molar extractions performed in 3,513 outpatients of the Department of Oral and Maxillofacial Surgery (University of B...

PURPOSE Mandibular fracture after impacted lower third molar removal is a rare, but major, complication. The factors leading to a mandibular fracture secondary to third molar removal are analyzed retrospectively. PATIENTS AND METHODS Six patients who suffered from a mandibular fracture as a complication after third molar removal were examined clinically and radiographically. RESULTS All fra...

Tooth agenesis is the most common of all dental developmental disorders. The mandibular second premolars are the teeth most commonly found missing (2.2 to 4.1%) after the third molars. There are more studies on tooth agenesis than the other malformations but yet they are limited. This article reviews the studies related to agenesis of mandibular second premolars and the underlying mechanisms be...
