adenoid cystic carcinoma (adcc) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). about 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). three clinically obvious characteristics of adcc include slow growth rate, perineural invasion and high incidence of distant metastasis (1). the most commonly-affected sites of...

squamous cell carcinoma (scc) of the buccal mucosa accounts for 23% to 37% of all intraoral cancers, the prognosis is generally poor. we reported a case of local invasion of buccal squamous cell carcinoma. a 32-year-old man referred to the clinic with a chief complaint of swelling in the right cheek region that initiated from 6 months ago and rapidly grow from one month ago. history of the pati...

it is difficult to reconstruct an alar defect with cartilage involvement. here in the authors report a case of traumatic alar loss during childhood in which an alar reconstruction was carried out with a composite auricular graft put over the pedicle buccal flap which was rotated and passed through the intraoral side. the lining skin and auricular cartilage for the flap was obtained from the aur...

Pullulan, a water soluble, bioadhesive and biocompatible biopolymer is used as an efficient matrix for enalapril maleate film preparation. The obtained film contains as much as 67% of enalapril maleate, relative to the initial amount used for experiments. The drug content was evaluated by using 1 H-NMR and UV-vis spectroscopy. The pullulanenalaprilmaleate blends exhibit good physicochemical pro...

Purpose: To prepare and characterise ciprofloxacin mucoadhesive buccal films for localised, improved drug delivery in periodontitis. Methods: Ciprofloxacin-loaded buccal films containing 50 mg ciprofloxacin were prepared mucoadhesive polymers sodium cellulose (SCMC) and sodium alginate, using a solvent evaporation method. The films were evaluated in terms of thickness, weight, folding endurance...

Different feeding-related behaviors in Aplysia require substantial variations in the coordination of movements of two separate body parts, the lips and buccal mass. The central pattern generators (CPGs) and motoneurons that control buccal mass movements reside largely in the buccal ganglion. It was previously thought that control of the cerebral neuronal circuitry and motoneurons that generate ...

Buccal delivery involves the administration of the desired drug through the buccal mucosal membrane lining of the oral cavity.The objective of this article is to review buccal drug delivery by discussing the structure and environment of the oral mucosa and highlighting the mechanisms of drug permeation and methodology in evaluating buccal formulations. This review also highlights a brief descri...

This study aimed to test the sterility of new unused orthodontic buccal tubes received from manufacturers. Four different types of buccal tubes were used straight from the manufactures package without any additional sterilizing step. Of these buccal tubes tested, three genera of bacteria, implicated as opportunistic pathogens, namely Micrococcus luteus, Staphylococcus haemolyticus and Acinetoba...
