BACKGROUND Orthopedic functional devices, are used to improve mandibular length in skeletal class II patients. However, the orthopedic functional device with the best effect to increasing the mandibular length, has not been identified before. Thus, the aim of the present investigation was to evaluate Randomized Controlled Trials (RCT), to determine the best functional appliance improving mandib...
Objective: Having detailed knowledge about the anatomical structure of mandible is important for anthropologists, forensic scientists and reconstructive surgeons. There are several imaging modalities visualizing the mandibular morphology. Cone Beam Computed Tomography (CBCT) is a developing technique that is being increasingly used in dento-maxillo-facial imaging due to its relatively low dose ...
Mandibular second premolars and maxillary central incisors usually have one root, one canal, and one apical foramen. However, some studies have revealed anatomic variations in these teeth. The aim of the present study was to investigate such variations in canal configuration, foramina, lateral and accessory canals and apical deltas in the root apex of human maxillary central incisors and mandib...
PURPOSE This study evaluated the association between cone beam computed tomography (CBCT) and panoramic radiographs in the assessment of a superimposed relationship between the mandibular canal and impacted third molars. MATERIALS AND METHODS The study samples consisted of 175 impacted third molars from 131 patients who showed a superimposed relationship between the mandibular canal and third...
Ectomesenchyme, a derivative of the embryonic neural crest, forms the membrane bones of the mandibular skeleton, but will only do so after undergoing an inductive interaction with mandibular epithelium. Previously, non-mandibular epithelia have been shown to act as effective substitutes for the mandibular epithelium in this interaction. The role of epithelial viability was examined by enzymatic...
PURPOSE This study was performed to investigate the course of the mandibular canal on panoramic radiography and the visibility of this canal on both panoramic radiography and cone-beam computed tomography (CBCT). MATERIALS AND METHODS The study consisted of panoramic radiographs and CBCT images from 262 patients. The course of the mandibular canal, as seen in panoramic radiographs, was classi...
Abstract Ameloblastic fibroma is a relatively rare benign odontogenic tumor with two neoplastic components both epithelial and ectomesenchymal. A 10-year-old girl was referred to a dentist for routine dental treatments for evaluation of the distance between mandibular right first permanent molar and mandibular right second deciduous molar and it was associated with an undesirable backward mov...
OBJECTIVE The aim of this study is to investigate the multifactorial etiology of mandibular tori analyzing the influence of genetics, occlusal overload, various clinical variables and their interactions. METHODS Overall, plaster casts of 162 twins (81 twin pairs) were analyzed for the presence or absence of mandibular tori. Atypical wear facets on canine tips or incisors were recorded to diag...
