a 7.5 year-old girl was seeking orthodontic treatment because of severe ectopic eruption of maxillary first permanent molars. it was a rare case that represented approximately horizontal view in panoramic radiograph. the severity of problem was high, but since the patient had maxillary deficiency, it was important to perform the treatment without extraction. treatment began with extraction of u...

radiographic evaluation of the third molar tooth to determine its position and degree of development is an important part in diagnosis and treatment planning, as well as in forensic dentistry procedures. the objective was to investigate the developmental stages of third molars in relation to chronologic age, gender and location (maxillary/mandibular) in an iranian population.the data were colle...

OBJECTIVES We retrospectively evaluated the impact of mandibular third molars on the occurrence of angle and condyle fractures. MATERIALS AND METHODS This was a retrospective investigation using patient records and radiographs. The sample set consisted of 440 patients with mandibular fractures. Eruption space, depth and angulation of the third molar were measured. RESULTS Of the 144 angle f...

Molar optimality models assume that any reward schedule can be described by a molar feedback function, which is the relation between average response rates and average reinforcement rates enforced by that particular schedule. This molar feedback function is considered, by optimality models, to be a sufficient description of the schedule for the prediction of steady-state molar performance. In t...

Familial recurrent molar pregnancy is an exceedingly rare condition, in which complete hydatidiform moles are mostly diploid but biparental in origin and the outcome of subsequent pregnancies is likely to be a hydatidiform mole or other type of reproductive loss. We previously reported a case of familial molar pregnancy (family K) comprising five affected members (four sisters and one of their ...

The maxillary first molar usually has single palatal root. Incidence rate of maxillary first molar with two palatal roots is especially rare. We reported a case of young maxillary first molar with two palatal roots in this article. Anatomic characteristic of permanent maxillary molar is generally described as a group of teeth with three roots, one palatal and two buccalbut the root canal system...
