Introduction The frenula of the oral vestibule include the labial and buccal frenula. Abnormal labial and buccal frenula can affect facial esthetics and oral cavity function by retracting the gingival margin, creating a median diastema, and limiting lip movement. Because of the lack of information on these structures, we aimed to clarify their anatomy.  Methods A total of 34 sides from 17 fresh...

In recent years, minor salivary glands, due to their involvement in the health and homeostasis of the oral cavity, have been the focus of several research investigations. Despite the fact that a considerable amount of data has been collected, many aspects of their functional features, including the secretory components they produce, remain to be ascertained. In this study we have analyzed the u...

We conducted a prospective study to compare the effectiveness of conventional computed tomography (CT) and puffed-cheek CT in detecting the presence and extension of oral cavity malignant tumors. We enrolled 11 patients--5 men and 6 women, aged 32 to 85 years--who had a primary squamous cell carcinoma of the oral cavity. These tumors were located in the floor of the mouth in 4 patients, in the ...

OBJECTIVES The primary goal of prosthetic obturation is closure of the maxillectomy defect and separation of the oral cavity from the sinonasal cavities by use of different bulb designs. The aim of this study was to evaluate the articulation performance of obturator patients with three different buccal extension designs. METHODS Five patients with palatal defects of comparable sizes at ages r...

Lipoma, a benign tumour of adipose tissue, is one of the most common benign neoplasms of the body. However, its occurrence in oral cavity is relatively rare. It accounts for 1 to 4% of benign neoplasms of the oral cavity, affecting predominantly buccal mucosa, floor of mouth and tongue. They have been known to grow to sufficiently large sizes causing problems in mastication and speech. The usua...

Background and Aim: Several surgical techniques have been so far used for treating Cerebrospinal Fluid (CSF) leakage (rhinorrhea) such as using abdominal fat or fascia lata, but these methods have complications such as the presence of several surgeons in variable fields in the operating room or cosmetic complications for donors such as the surgical scar. This study aimed to investigate using bu...

the aim of this retrospective statistical study was to determine the prevalcence and frequency of age and sex distributions of pemphigus disease. pemphigus disease classified as autoimmune bullous dermatoses which is a chronic mucocutaneous disease.this study was performed in razi hospital and department of oral pathology of dental school, tehran university of medical sciences. the most frequen...

Pontonema golfonuevensis sp. nov. from Chubut Province, Argentina is described and a description of the male of Pontonema incisum Wieser, 1953 from Chubut and Santa Cruz Provinces is provided. Pontonema golfonuevensis sp. nov. is characterized by having the slender sub-ventral teeth 25 µm long located at 24 % of stoma length, a short, broad dorsal tooth at 60 % of stoma length, excretory pore o...

Caenorhabditis elegans is a filter feeder: it draws bacteria suspended in liquid into its pharynx, traps the bacteria, and ejects the liquid. How pharyngeal pumping simultaneously transports and filters food particles has been poorly understood. Here, we use high-speed video microscopy to define the detailed workings of pharyngeal mechanics. The buccal cavity and metastomal flaps regulate the f...
