OBJECTIVES The association between viral hepatitis (B and C) and oral cavity cancer has been widely debated. This nationwide, population-based cohort study assessed the subsequent risk of oral cavity cancer among patients with chronic viral hepatitis infection. MATERIALS AND METHODS Data were retrieved from insurance claims data of 1,000,000 randomly sampled individuals covered under the Taiw...

OBJECTIVE To test the hypothesis of a bidirectional association of anogenital and oral cavity/pharyngeal human papillomavirus (HPV)-associated cancers in men. DESIGN Population-based epidemiological study using the Surveillance, Epidemiology, and End Results cancer database. SETTING Population-based cancer study involving patients receiving care in the United States. PARTICIPANTS The stud...

Receptors located in the posterior oral cavity and on the epiglottis play an important role in the initiation of upper airway reflexes such as swallowing, gagging, coughing and apnea. Peripheral nerves which innervate these receptor areas terminate in the nucleus tractus solitarius (NTS). We have recorded the responses of 61 neurons in the lamb NTS to stimulation of the caudal tongue, palate an...

The oral cavity can act as a reservoir of certain pathogens that can cause systemic infections. The periodontal pocket is an ecological niche appropriate for hosting microorganisms that could act as opportunistic pathogens. The ability of Staphylococcus spp and Candida spp to form a biofilm and live within certain niches allows them to develop mechanisms that increase persistence, such as the e...
