351 P of mandibular molars is challenging because of the high density of mandibular bone. Anterior dental anchorage is often inadequate to protract even a single first molar without reciprocal retraction of the incisors or movement of the dental midline. Furthermore, if the buccal and lingual cortical plates in the edentulous region have collapsed, safe and effective protraction may be impossib...

The mandibular infected buccal cyst or mandibular bifurcation cyst is a cystic lesion that occurs on the buccal surface of the permanent mandibular first or second molar in children aged around 6-8 years. We report the clinical, radiographic, and histological features and the treatment of a mandibular infected buccal cyst of the first molar in a 7-year old child. 1 year follow up after the enuc...

The location and configuration of mandibular canal variations are important in surgical procedures involving the mandible, such as extraction of an impacted third molar, dental implant treatment, and sagittal split ramus osteotomy. We report 3 Japanese patients with bifid mandibular canals using panoramic radiograph and multi-slice helical computed tomography (CT) images. In 2 of the 5 sides, t...

Objective: To assess the reliability of fi ve intra oral periapical radiography (IOPAR) radiographic signs, and to compare the reliability of IOPAR with that of cone-beam computerized tomography (CBCT) for determining the proximity of impacted mandibular third molar and mandibular canal. Methods: The present study consisted of 50 subjects, in age group of 18-30 years with impacted mandibular th...

Data are presented on the frequency of the following eight dental traits in 635 Yanomama and 65 Makiritare Indians: upper central incisor rotation or winging, shoveling of maxillary incisors, maxillary molar hypocone reduction, Carabelli's trait, mandibular molar cusp number, mandibular molar cusp pattern rotation of second lower premolar, and pattern of second lower premolar cusps. Yanomama de...

single rooted primary mandibular first molar is a rare developmental anomaly. literatures reveal that failure of invagination of hertwig's epithelial root sheath leads to this unusual root form. thorough knowledge of root canal morphology and anatomical variations of primary teeth can help a pediatric dentist in successful root canal treatment. hereby, we describe two cases of primary mandibula...

Introduction: The purpose of this study was to evaluate the relationship between the position of mandibular third molar (M3) and vertical skeletal malocclusions. Methods: Materials for the study consisted of panoramic radiographs and lateral cephalograms of 73 fifteen to nineteen-year-old class I patients (girls=66%, boys= 34%). Patients were classified into three groups based on four vertical ...
