No tooth is as problematic for patients it third molars. After erupting later than all teeth, they often have little space in the dentition, or rather retromolar space, which should appear, above all, with further growth of jaws. Therefore, timing their eruption varies considerably and accompanied by appearance significant morphological functional disorders. That why necessary to take a balance...

PURPOSE We sought to determine the incidence of caries experience on the occlusal surface of asymptomatic third molars erupted to the occlusal plane and to examine the association between the prevalence of caries experience in third molars and other molars. PATIENTS AND METHODS Clinical data were collected from healthy patients (ASA Class I, II) with asymptomatic third molars enrolled at 2 cl...

introduction: the aim of this study was to identify the root and canal morphology of maxillary first and second molars in iranian population by taking and analyzing cone-beam computed tomography (cbct) scans. methods and materials: extracted maxillary first ( n =125) and second ( n =125) molars were collected from native iranians and scanned by using a cbct scanner. the number of roots and conf...

The main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. Failure to find and fill a canal contributes toward the failure of endodontic therapy .The root canal anatomy of mandibular first molars is complex. Studies of the morphologic structure of root canal systems hav...

BACKGROUND Root resection is one treatment option for preserving molars with furcation involvement. This study evaluated the prognosis of root-resection therapy retrospectively and examined the factors influencing the survival rate of resected molars. METHODS Root-resection therapy was performed on 691 molars in 579 patients. The associated factors were examined from 342 of 402 molars that ha...
