the presence of supernumerary teeth is not uncommon in the general population. they occur more frequently in patients with a family history of such teeth but it is rare to find multiple supernumeraries in individuals with no other associated disease or syndrome. there have been very few documented cases of bilateral maxillary and mandibular supernumeraries, distal to the third molars. supernume...

The occurrence of supernumerary teeth is a relatively uncommon dental anomaly and it's rare for patients to have impacted fourth molars in all quadrant. Aim of this work is to describe the presence of bilateral fourth molars in the maxilla and the mandible in a young male patient aged 22 years came to our hospital with acute pericoronal infection around unerupted third inferior molars. Routine ...

Panoramic radiographs of two female patients ages 22 and 21 revealed the presence of two impacted bilateral upper fourth molars and unilateral (right) upper fourth and fifth molars. All of the teeth were distomolars. The supernumerary teeth had normal tooth morphology with regard to their crowns and roots but were slightly smaller than the existing third molars. Their crowns were either two or ...

Mandibular third molars are the most common impacted teeth. Mandibular first and second molars do not share the same frequency of occurrence. In rare cases the occlusal surfaces of impacted molars are united by the same follicular space and the roots pointing in opposite direction; these are called kissing molars. In some cases, a supernumerary fourth molar can be seen as unerupted and, in this...

BACKGROUND An increase in tooth number is an exception during mammalian evolution. The acquisition of the lower fourth molar in the bat-eared fox (Otocyon megalotis, Canidae, Carnivora, Mammalia) is one example; however, its developmental origin is not clear. In some canids (Canidae), individual variation exist as supernumerary molar M4. This study focuses on the acquisition of the lower fourth...

INTRODUCTION "Kissing" or "rosetting" of molars refers to contacting occlusal surfaces of impacted permanent mandibular second, third, and, very rarely, fourth molars. It is a rare phenomenon. AIM The aim of this study was to assess the incidence, dental involvement type, associated pathologies and treatment outcomes of kissing molars in all patients who underwent lower third molar surgery be...

OBJECTIVE The purpose of this study was to investigate the root/number of roots and morphology of mandibular premolars and molars in a Korean population, and to evaluate the prevalence of three-rooted mandibular first molars having distolingual (DL) roots, three-rooted mandibular second molars, and C-shaped roots in mandibular second molars. METHODS Serial axial cone-beam computed tomography ...
