objective: the present study assessed the association of size, axial angulation, developmental stage and bud position of the mandibular third molar with the second molar impaction in patients with mandibular second molar impaction. methods: in this descriptive-analytical study (case-control design), dental records of 5,420 patients in the age range of 12-15 years who underwent orthodontic treat...
background and aims. a through knowledge of the root canal morphology is required for successful endodontic therapy. the aim of this study was to investigate the root and canal morphology of mandibular third molars in kerman, a province in southeast of iran. materials and methods. one-hundred-fifty extracted mandibular third molars were collected randomly from different dental clinics in kerman...
third molar eruption is an unpredictable event. occasionally, mandibular third molars undergo angular changes in young adults. this rotational drift is of unknown etiology, is not predictable and may facilitate the eruption or may make the impaction worse. a rare case is presented with severe rotational drift of a mesioangularly impacted mandibular third molar.
statement of the problem this study was designed to investigate the complications after surgical removal of mandibular third molars. patients and methods six hundreds and ninety eight lower third molars among 450 patients surgically extracted by general dentists from april 2005 to april 2006 were selected for this study. data were recorded by completing questionnaires regarding post surgical co...
Objectives Mandibular third molar extraction is among the most commonly performed dental procedures. Fracture of the angle of mandible after third molar extraction is a rare complication of this procedure. Case Herein, we report fracture of the right angle of mandible immediately after extraction of mandibular right third molar in a 38-year old healthy female patient, which was surgically mana...
Analysis and evaluation of relative positions of mandibular third molar and mandibular canal impacts
OBJECTIVES This study used cone-beam computed tomography (CBCT) images to categorize the relationships between the mandibular canal and the roots and investigated the prevalence of nerve damage. MATERIALS AND METHODS Through CBCT images, contact and three-dimensional positional relationships between the roots of the mandibular third molar and the mandibular canal were investigated. With this ...
Introdouction: Impacted mandibular third molar surgery may affect periodontal status of the adjacent second molar. The purpose of this study was to evaluate the changes in periodontal health parameters distal to the adjacent second molar following surgical extraction of an impacted mandibular third molar. Materials and methods: We selected 50 subjects with a mean age of 22.8 (ranging from 18...
Objective: The present study assessed the association of size, axial angulation, developmental stage and bud position of the mandibular third molar with the second molar impaction in patients with mandibular second molar impaction. Methods: In this descriptive-analytical study (Case-Control Design), dental records of 5,420 patients in the age range of 12-15 years who underwent orthodontic treat...
BACKGROUND Fractures of the mandibular angle are common and comprise 31% of all mandibular fractures. Multiple recent studies report a 2-3 fold increased risk for mandibular angle fractures when un-erupted mandibular third molars are present. The objective of this study was to assess the frequency of un-erupted mandibular third molar in mandibular angle fractures. METHODS This cross-sectional...
