buccal cavity as a compound ecosystem has always been ignored in parasitic infection studies; however it seems that studying on mouth and tooth prevalent parasitic infections is of great importance. in this study, from 120 patients of both sexes referred to faculty of dentistry, tehran university of medical sciences, iran, (2001-2002) 240 samples were taken from the plaques and calculus of dept...

Intraoral herniation of the buccal fat pad is traumatic lesion of oral cavity occurring in young children. It frequently presents as an expanding pedunculated mass of soft tissue emanating from the buccal mucosa following a minor trauma to the buccal soft tissues. This article aims to report an interesting and rare lesion, wherein a tiny traumatic perforation of the buccal mucosa and buccinator...

The ontogeny of suction feeding performance, as measured by peak suction generating capacity, was studied in the common snook, Centropomus undecimalis. Suction pressure inside the buccal cavity is a function of the total expansive force exerted on the buccal cavity distributed across the projected area of the buccal cavity. Thus, the scaling exponent of peak suction pressure with fish standard ...

OBJECTIVES/HYPOTHESIS To determine whether buccal squamous cell carcinoma has worse overall survival (OS) and disease-specific survival (DSS) than cancers in the rest of the oral cavity. STUDY DESIGN Retrospective analysis of a large population database. METHODS We began with a Kaplan-Meier analysis of OS and DSS for buccal versus nonbuccal tumors with unmatched data, followed by an analysi...

Suction feeding in fishes is the result of a highly coordinated explosive expansion of the buccal cavity that results in a rapid drop in pressure. Prey are drawn into the mouth by a flow of water that is generated by this expansion. At a gross level it is clear that the expansion of the buccal cavity is responsible for the drop in pressure. However, attempts using high-speed video recordings to...

The larval stage of the tiger salamander Ambystoma tigrinum is entirely aquatic, but the larvae rely on their lungs for a large proportion of their oxygen uptake. X-ray video and pressure measurements from the buccal and body cavities demonstrate that the larvae inspire using a two-stroke buccal pump and exhale actively by contracting the hypaxial musculature to increase body pressure. Larvae b...

Functional analysis of lung ventilation in salamanders combined with historical analysis of respiratory pumps provides new perspectives on the evolution of breathing mechanisms in vertebrates. Lung ventilation in the aquatic salamander Necturus maculosus was examined by means of rineradiography. measurement of buccal and pleuroperitoneal cavity pressures, and electromyography of hypaxial muscul...

An uncommon traumatic pseudolipoma of the oral cavity is presented. In this particular case there was evidence of previous trauma to the buccal fat pad during a difficult extraction of a maxillary premolar. Evidence is presented that iatrogenic trauma resulting in foreign body introduction might produce traumatic pseudolipoma in the oral cavity. The morphology of the buccal fat pad, the possibl...

ABSTRACT: Within the oral mucosal cavity, the buccal region offers an attractive route of administration for systemic drug delivery. The mucosa has a rich blood supply and it is relatively permeable. It is the objective of this article to review buccal drug delivery by discussing the structure and environment of the oral mucosa and the experimental methods used in assessing buccal drug permeati...
