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...
Background and aim: Increased rate of micronucleus in buccal mucosa cells and its correlation with carcinogenesis is worth consideration. Recently, occupation in dental laboratories has been proposed as a predisposing factor. Therefore, the present study aimed to evaluate the effect of occupational exposure on buccal mucosa cells of dental laboratory technicians. Materials and methods: This ...
Our aim was to investigate the effect of Withaferin-A on bone marrow micronucleus frequency and buccal mucosa detoxication agents during 7, 12-dimethylbenz[a]anthracene (DMBA) induced hamster buccal pouch carcinogenesis. Oral squamous cell carcinoma was developed in hamsters' buccal pouches by painting 0.5% DMBA in liquid paraffin, three times per week for 14 weeks. We observed 100% tumor forma...
BACKGROUND Analysis of myocardium has revealed mechanistic insights into arrhythmogenic cardiomyopathy but cardiac samples are difficult to obtain from probands and especially from family members. To identify a potential surrogate tissue, we characterized buccal mucosa cells. METHODS AND RESULTS Buccal cells from patients, mutation carriers, and controls were immunostained and analyzed in a b...
Aim: The aim of this study was to analyze cytologically the buccal mucosa, tonge dorsum and floor of the mouth in diabetic patients and healthy volunteers to determine what cellular changes are affected by diabetes mellitus. Method: In order to evaluate cellular changes induced by diabetes mellitus, exfoliative cytology was used for the analysis of buccal mucosa, tongue dorsum and floor of the ...
adenoid cystic carcinomas are deceptive malignancies that show slow growth and local invasion with recurrences seen many years after diagnosis. upto 50% of these tumors occur in the intraoral minor salivary glands usually in the hard palate. buccal mucosal tumors are relatively rare. we determined the incidence of buccal mucosal adenoid cystic carcinoma by reviewing the number of reported cases...
Waterpipe Tobacco Smoke(WTS) is an unhealthy life style that may increase the risk of genotoxic responses and chronic diseases such as cancer. Micronucleus test is a successful and reliable method which is used for screening of genetotoxic responses of whole body and also for screening those people who had already exposed to genotoxic compounds. In this study, specific questionnaires were desig...
Glutathione S-transferase (GST) activity and amount of GST alpha, mu and pi isoforms were measured in 40 patients with histopathologically confirmed oral epithelial dysplasia (OED) and squamous cell carcinoma of buccal mucosa. The results were compared with those of normal mucosa in an equal number of age- and sex-matched healthy controls. Mean total GST activities were significantly elevated f...
The aim of this study was to determine whether buccal mucosa would provide an alternate source of tissue for human biomonitoring. Samples of clinically normal oral biopsies were excised, and buccal mucosa were scraped or brushed from patients while they were undergoing surgery for the excision of intra-oral squamous cell carcinoma. Extracted DNA was 32P-postlabeled using the butano! enhancement...
background :the diagnosis of malignant and potentially malignant epithelial lesions of the oral mucosa cannot be based solely on clinical findings. therefore, histologic evaluation of a representative biopsy specimen is necessary. however the site for the biopsy is always a subjective choice that sometimes raises doubts about its representativeness. colposcopy, a well-known gynecological diagno...
