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...

AIM To measure the root canal area and the reduction of the mesial and buccal/lingual wall thickness at the level of the coronal interference in mesial roots of mandibular molars after instrumentation with a crown-down or a simultaneous root canal preparation technique. METHODOLOGY Twenty mesial roots of first mandibular molars with a moderate root canal curvature were embedded in resin and s...

Objective In the present study, we investigated the brain interhemispheric functional connectivity changes in left eye MB versus right eye MB patients by voxel-mirrored homotopic connectivity (VMHC) methods. Methods A total of 31 patients with MB (15 with left eye MB and 16 with right eye MB), and 31 healthy controls (HCs) closely matched for age were recruited. All subjects underwent functio...

Transitions between aquatic and terrestrial prey capture are challenging. Trophic shifts demand a high degree of behavioral flexibility to account for different physical circumstances between water and air to keep performance in both environments. The Himalayan newt, Tylototriton verrucosus, is mostly terrestrial but becomes aquatic during its short breeding period. Nonetheless, it was assumed ...

Introduction. This study aimed to evaluate the influence of oral appliances (OAs) on dentition using a strain gauge analysis. Materials/Methods. Eight volunteers, who were mild snorers, participated in this study. OAs were individually constructed, and advancement was defined as two-thirds of the maximum mandibular advancement. Strain gauges were mounted on the right first molar and central inc...

Geographic tongue (GT) is an oral mucosal lesion that affects the tongue. The association between GT and the bacterial colonization profiles of the tongue is not clear. Lingual swabs were collected from lesion sites and healthy sites of 35 patients with GT (19 males and 16 females; Mage = 54.3 ± 16.1 years) and 22 controls (12 males and 10 females; Mage = 56.3 ± 15.8 years). Bacterial DNA was e...

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...
