This study aimed to investigate cytological abnormalities indicative of chromosome damage (micronuclei) and apoptosis (karyorrhexis, pyknosis, and condensed chromatin) in exfoliated cells from the buccal mucosa of patients with oral cancer and control subjects. The sample included twenty individuals with oral cancer and forty individuals with normal buccal mucosa. Material was collected from th...

Squamous cell carcinoma (SCC) is the most malignant neoplasm of the oral cavity. The mortality rate associated with head and neck cancers remains high, and thus detection techniques are important. In the present study, methyl green-pyronin staining was applied to 5 normal mucosa specimens, 10 cases of dysplastic mucosa, 12 cases of SCC (grade I), 10 cases of SCC (grade II) and 5 cases of SCC (g...

The population of Brazil is experiencing a fast and progressive aging process. Oral mucosa, which has a function as a barrier, is compromised by the aging process, allowing the action of predisposing agents. The older the population, the greater is the prevalence of lesions in oral mucosa. The causes may be neoplastic, infectious, bone pathologies, oral manifestations of systemic diseases, nutr...

Lichen planus pigmentosus (LPP) is a variant of lichen planus. It characterized by small black, brown macules, on sun exposed areas like face, neck, upper extremities and trunk. Lesions are insidious in onset with gradually progressive course. Few variants have been reported LPP inversus, localized LPP, linear zosteriform oral mucosa etc. Here, we present case young adolescent male, which rare ...

introduction: peripheral reactive lesions of soft tissue are common oral lesions that dentists face during routine examinations. diagnosis and development of a treatment plan is difficult if dentists are not aware of the prevalence and clinical symptoms of these lesions. the frequency of these lesions differs across various populations. the aim of this study was to determine the frequency and d...

We tested 65, 44, and 116 patients with oral squamous cell cancer (OSCC), oral leukoplakia (OL), and oral lichen planus (OLP) against 68 age-matched controls for the presence of Epstein-Barr virus (EBV). Apparently healthy mucosa was simultaneously sampled and examined in all patients. Paraffin-embedded tissue sections of all EBV-positive patients with OSCC were examined for latent membrane pro...

BACKGROUND/AIM To investigate the relative frequency of biopsied nonneoplastic oral mucosal lesions in Ankara, Turkey. MATERIALS AND METHODS Biopsy records of a single center from 2000-2012 were retrospectively collected. Diagnosis was recorded and evaluated with respect to patient demographics (age, sex) and location of the lesion. RESULTS Of 11,980 biopsies, 1732 (14.5%) were mucosal nonn...

INTRODUCTION Multibacillary leprosy may involve the oral mucosa, with or without apparent lesions. There are few studies that deal with this issue in the era of multidrug therapy. AIM To assess the frequency of oral mucosa involvement in multibacillary leprosy patients. PATIENTS AND METHODS A transversal study with twenty non-treated multibacillary leprosy patients.
