PURPOSE To assess the relationship between mandibular asymmetry and disorders of the temporomandibular joint. METHODS We used advanced imaging of the temporomandibular joint to distinguish different causes of mandibular asymmetry. MR imaging and arthrography were applied to the temporomandibular joints of 11 patients presenting with mandibular asymmetry. RESULTS Condyle hyperplasia was iden...

Impacted mandibular third molars can be located in close proximity to the mandibular canal. This creates a risk for the nerve or artery injury. These are contained in the canal. However, the impacted third molar can be moved coronally by orthodontic means, after removal of overlying bone, and safely extracted. The orthodontic intervention slowly moves the tooth apex away from the mandibular can...

A panoramic radiographic study was carried out on 404 dentate Saudi Arabians, to locate positions of the mental foramen. Results show that 83.7% of the mental foramen locations occurred in the interdental space between the mandibular premolars and apical to the mandibular second premolar. 9.35% occurred posterior to the mandibular second premolar, and 6.95% occurred apical/anterior to the mandi...

The study involved 100 male and 100 female children of age 6-10 Years. 80(80%) males exhibited evidence of simultaneous presence of dental car...

conclusions evaluating the size of the patient’s pupils before, during and after the operation, careful history, consult, ct scan and mri would help to diagnosis. although no probable cause was found to explain the transient mydriasis in our patient. introduction unilateral mydriasis is a seriously significant finding in neurologic examinations indicating life-threatening conditions such as cer...

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...

talon cusp is a dental anomaly also known as an eagle’s talon. it is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. the exact etiology is unknown. the incidence of talon cusp is less than 6%. commonly involved teeth are maxillary incisors, usually unilateral but in some instances bilateral. the classical ra...
