OBJECTIVE Lingual nerve damage sometimes occurs after the removal of third molars. The use of a lingual retractor has been advocated to protect the lingual nerve. A systematic review of the literature was undertaken to evaluate the incidence of lingual nerve damage after third molar surgery and the effect of a lingual retractor on nerve damage. STUDY DESIGN An exhaustive computerized search o...

Posterior fossa ependymoma comprises two distinct molecular entities, ependymoma_posterior fossa A (EPN_PFA) and ependymoma_posterior fossa B (EPN_PFB), with differentiable gene expression profiles. As yet, the response of the two entities to treatment is unclear. To determine the relationship between the two molecular subgroups of posterior fossa ependymoma and treatment, we studied a cohort o...

PURPOSE The aim of this study was to analyze the shapes of lingual polished surfaces in lower complete dentures formed by polished surface impressions and to provide reference data for use when manufacturing edentulous trays and lower complete dentures. MATERIALS AND METHODS Twenty-six patients with mandibular edentulism were studied. After lower wax dentures were fabricated, wax was removed ...

Purpose: To assess the anatomic variation with the frequency, location, and morphology of mandibular lingual foramina using Cone Beam Computed Tomography. Methods: A retrospective study from CBCT examination of 200 subjects was conducted. The canal frequency (number), location, and travel direction were assessed by selecting images of the mandible. Also, linear dimensions such as the diameter o...

background and aims. occlusal rims are used to determine the jaw relationships in the transverse and vertical dimensions and estimate the inter-occlusal distance in edentulous patients. it is important to find ways to determine the height and shape of the occlusal rims correctly. the aim of the present study was to determine the exact distance between the oral cavity floor and the incisal edges...
