background and objectives: split sagittal osteotomy is a common operation that may induce inferior alveolar nerve (ian) damage, potentially leading to sensory deficit, numbness, and pain. investigations in iran to evaluate the adverse effects of sagittal split osteotomy surgery are rare so questions have been raised about the success rate of operation and the frequency of unwilling outcome. to ...

OBJECTIVE The purpose of this study was to evaluate the accuracy of relative measurements from the roof of the mandibular canal to the alveolar crest in multislice (multidetector) computed tomography (MDCT) and single-slice computed tomography (SSCT). MATERIAL AND METHODS The sample consisted of 26 printed CT films (7 SSCT and 19 MDCT) from the files of the LABI-3D (3D Imaging Laboratory) of ...

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...

OBJECTIVES Achieving adequate anesthesia with inferior alveolar nerve blocks (IANB) is of great importance during dental procedures. The aim of the present study was to assess the success rate of two anesthetic agents (bupivacaine and lidocaine) for IANB when treating teeth with irreversible pulpitis. MATERIALS AND METHODS Sixty volunteer male and female patients who required root canal treat...

Inferior alveolar nerve block obtained maximum anesthetic effect using a small dose of local anesthetic agent, which also has low a complication incidence. Complications of an inferior alveolar nerve block include direct nerve damage, bleeding, trismus, temporary facial nerve palsy, and etc. Among them, the major iatrogenic complication is dental needle fracture. A fragment that disappears into...

The mandibular canal divides into the mental and incisive canals at the premolar region, forms the anterior loop which crosses anterior to the mental foramen, and turns back to reach the mental foramen. The aim of this study was to elucidate the general anatomical structure of the anterior loop of the mandibular canal using morphometry. Twenty-six hemimandibles from 19 cadavers (16 males, 3 fem...
