Accuracy of MRI, CT, and Ultrasound imaging on thickness and depth of oral primary carcinomas invasion: a systematic review.

Objectives: The aim of this study was to perform a systematic review to assess the sensitivity, specificity, and accuracy of magnetic resonance imaging (MRI), computed tomography (CT), and intraoral ultrasound (US) to determine the depth of invasion (DOI) and/or tumor thickness (TT) in oral cavity cancers, with histopathological evaluation as the gold standard.

Methods: Articles whose primary objective was to evaluate the accuracy (sensitivity and specificity) of MRI, CT, and US imaging to assess DOI and/or TT were searched in six major electronic databases, in addition to three grey literature databases. The methodological quality of the selected studies was evaluated by using the Quality Assessment Tool for Diagnostic Accuracy Studies-2.

Anesthetic Efficacy of an Alternative Inferior Alveolar Nerve Block Technique Using an Extra-Short Needle: A Double-Blind Randomized Non-Inferiority Trial.

Purpose: Inferior alveolar nerve block (IANB) is a frequently used anesthetic technique for restorative and surgical procedures in the mandible and its success rate usually ranges from 80 to 85%. Thus, this study aimed to compare the anesthetic efficacy of an alternative technique named superficial nerve block (SNB)-which consists of a modified approach using an extra-short needle inserted 10 mm deep and on a higher injection site to the conventional technique (CT) for IANB in healthy individuals.

Methods: About 20 participants received both SNB and CT with 1.

HNK1 and Sox10 are present during repair of mandibular bone defects.

Neural crest cells possess characteristics of stem cells including plasticity and ability to differentiate into various cell types. HNK1 and Sox10 are markers of neural crest cell progenitors that have been demonstrated in osteoblasts during osteogenesis of the maxilla and mandible. We investigated the presence of Sox10 and HNK1 during regeneration of mandibular bone defects.

Dystrophic calcification and respiratory metaplasia in the epithelial lining of odontogenic cysts: a study of 362 odontogenic cysts in a Brazilian population and literature review.

Purpose: Main study: undertake a histological study of odontogenic cysts (OC) to determine the prevalence of dystrophic calcification and metaplasia to respiratory epithelium on a Brazilian population.

Literature Review: to review the literature for studies that investigated the prevalence of respiratory metaplasia and dystrophic calcification on OC.

Methods: Main study: a retrospective histopathological evaluation was made of the archives from a pathology laboratory.
