Introduction: A strong relationship exists between cigarette smoking and the development of oral squamous cell carcinoma. Smoking can significantly increase cellular proliferation. Nevertheless, there is little reference in literature to the cytological assessment of oral mucosa in this respect. Methods: Changes in nuclear and neucleolar cytomorphometric parameters such as diameter, surface, nu...

Background: Superficial mucocele presents as small, clear vesicle on noninflamed mucosa. In this study, we report several vesicles on the bucal mucosa of a woman diagnosed as superficial mucocele.Case Presentation: A 48-year old woman presented with multiple vesicles on her labial mucosa, ventral surface of the tongue, floor of the mouth and palate. A mucosal biopsy was taken from the vesicle. ...

Introduction: Reconstruction of the oral cavity witha flap design containing the buccal mucosa and buccinator muscle but excluding the facial artery and vein is the topic of these case reports. Case Reports: This article uses random pattern vertically oriented partial thickness buccinator myomucosal flap for intraoral reconstruction in two cases. The first was for lining the mandibular anterior...

background: squamous cell carcinoma (scc) is the most common malignancy in oral cavity. angiogenesis is essential for the development and progression of scc. recently, some studies have reported that mast cells may play a role in tumor progression via promoting angiognesis. since the results of various studies on the role of mast cells in tumor progression is not uniform, the aim of this study ...

Focal epithelial hyperplasia (FEH) is a human papillomavirus (HPV)-induced alteration of the oral mucosa that presents with a clinically distinct appearance. While other HPV-infected lesions such as squamous papilloma, verruca vulgaris, and condyloma acuminatum involve the skin, oral mucosa, and genital mucosa, FEH occurs only in the oral mucosa. The affected oral mucosa exhibits multiple papul...

The prevalence of prosthodontic treatment has been well recognized, and the need is continuously increasing with the ageing population. While the oral mucosa plays a critical role in the treatment outcome, the associated biomechanics is not yet fully understood. Using the literature available, this paper provides a critical review on four aspects of mucosal biomechanics, including static, dynam...

Oral mucosa has been used for reconstructing oral and maxillofacial defects for many years (Payne et al., 1998); in repairing the conjunctival mucosa of the eye (Donoff, 1976), in oral pharyngeal reconstructive surgery (Leone, 1995) and in reconstructing vaginal defects (Lin et al., 2003). Since the initial introduction by Humby (1941) and then the re-introduction by Burger, oral mucosa graft h...

In order to compare delayed-type hypersensitivity (DTH) among different exposure sites, we evaluated the sensitization potency of mercuric chloride (HgCl(2)) via exposure to the skin, or oral or esophageal mucosa using the mouse ear swelling test. Furthermore, we investigated in vitro splenocyte proliferation reaction and cytokine profile in HgCl(2)-exposed and control mice. Sensitization with ...

Several pathologies may affect the histological structure and physiology of human oral mucosa, being necessary to use mucosa grafts. In this context, scarce number donors has increased need develop artificial substitutes most them, without attending differences found in different anatomical areas cavity. The objective present bibliographic review is carry out a description morphological classif...

In secondary tuberculosis, lesions of the oral cavity may accompany lesions of the pharynx, lungs, lymph nodes or miliary tuberculosis. A 35-year-old male was suffering from swelling of his right cheek, cough, weakness and weight loss. There were local hyperemia and irregular oral mucous in the inner part of the right cheek. Chest x-ray showed bilateral nodular opacifications and a cavity of 2 ...
