Abstract Low‐level laser therapy (LLLT) is a non‐thermal phototherapy used in several medical applications, including wound healing, reduction of pain and amelioration oral mucositis. Nevertheless, the effects LLLT upon cancer or dysplastic cells have been so far poorly studied. Head neck patients receiving for mucositis, example, might remaining tumor that could be stimulated by LLLT. This study demonstrated (GaAlAs – 660 nm 780 nm, 40 mW, 2.05, 3.07 6.15 J/cm 2 ) can modify (DOK) (SCC9...
To perform an oral biopsy survey focused on the incidence of lesions in Brazilian elderly patients.A total 17 329 records were analysed and divided into two age groups: patients, > or =60 years old; non-elderly <60 old. Information about sex, race, histopathological diagnosis (categorised non-neoplastic neoplastic lesions) was collected. Differences tested by comparison between proportions (binomial test).The epithelial malignant neoplasms pre-malignant group higher than group, as well...
J Oral Pathol Med (2012) 41 : 272–280 Screening for expression of amelogenesis‐related proteins represents a powerful molecular approach to characterize odontogenic tumors and investigate their pathogenesis. In this study, we have examined the presence distribution ameloblast‐associated protein (ODAM), amelotin (AMTN), ameloblastin (AMBN), amelogenin (AMEL) by immunohistochemistry in samples adenomatoid tumor (AOT), calcifying epithelial (CEOT), developing odontoma, ameloblastoma, cystic...
The purposes of this study were to assess clinical, histopathological and immunohistochemical features 22 oral neurofibromas (NFs) discuss with previously described literature, addressing the main aspects regarding differential diagnosis.Immunohistochemical reactions included S-100, CD34, GLUT-1, EMA, Ki-67, p53 Collagen IV histochemical for Alcian blue.Clinically, preferential location was maxillary bones, tongue buccal mucosa. Microscopically, widely spread spindle-shaped cells scant...
Background Mucoepidermoid carcinoma ( MEC ) is the most common salivary gland malignancy and successfully treated by surgery radiation. However, some patients have recurrent tumours in these cases, few treatments options are available. Cancer stem cells CSC been observed isolated from different solid based on expression of cell markers. These associated with tumour initiation, progression as well treatment resistance. In this study, markers CD 44, Bmi1, Oct4 Nanog was evaluated...
A hamartoma is a benign proliferation of typical mature cells specific to particular anatomical site. In the oral cavity, they may occur as isolated cases or be associated with genetic syndromes. Oral-facial-digital syndrome type VI rare disorder an estimated incidence one in 50,000-250,000 newborns. Here, we report case 2-year-old boy diagnosed oral-facial-digital who was referred for evaluation bilateral and normochromic slightly pinkish nodule on lateral surface tongue. Clinically, child...
It is still controversial whether human papillomavirus (HPV) can be considered a risk factor in oral carcinogenesis. The aim of this study was to detect HPV DNA 50 cases diagnosed as leukoplakias, with different degrees epithelial dysplasia, and squamous cell carcinomas, using situ hybridization signal amplification (CSA-ISH).HPV assessed paraffin sections CSA-ISH wide-spectrum biotinylated probe. In HPV-positive cases, genotyping specific probes types 6/11, 16/18 31/33 performed.The overall...
The aim of this study was to evaluate the effects injection two phlogistic agents, carrageenan and formalin, in rat TMJ, inflammatory process induced by these substances. In study, a total 45 adult rats were distributed experimental groups control group. animals sacrificed after three hours, 24 days, seven 15 days single each substance. Histological data initially demonstrated an represented acute infiltration, which later became mixed, finally chronic both groups. Hyperplasia synovial...
Objective To evaluate the efficacy of M elaleuca alternifolia and C opaifera officinalis in inhibiting adhesion andida albicans biofilm. Background Over 65% denture wearers suffer from stomatitis, which is one most prevalent forms oral candidiasis. This disease characterised by inflammation mucosa contact with contaminated denture. The contributes to switch . yeast its pathogenic hyphal form. adheres colonises polymethylmethacrylate resin surfaces thus development stomatitis. Materials...
Background Although not rare, vascular lesions occurring in the lips sometimes poses a difficult properly diagnosing and handling them. In this study, were retrieved from an Oral Pathology Service. Methods Among 5600 biopsies, 131 cases found. The following diagnoses attributed: caliber‐persistent artery, infantile hemangioma, malformation, venous lake, thrombus, papillary endothelial hyperplasia pyogenic granuloma. Clinical data obtained patients’ records. Results lesions’ frequency were:...
Oral melanoacanthoma (OMA) is a rare benign lesion characterized by colonization of acanthotic epithelium dendritic melanocytes. Although its pathogenenesis remains uncertain, clinical behavior and spontaneous remission suggest non-neoplastic nature. Clinically, it may present as solitary or multifocal lesion; however these two variants exhibit different features. The appearance OMA not pathognomonic biopsy mandatory. requires no treatment periodic observation. Here, we report case with...
Marques Y M F S, Giudice Freitas V M, Abreu e Lima d C C, Hunter K D, Speight P & Machado de Sousa S O (2012) Histopathology 60, 609–616 Oestrogen receptor β in adenoid cystic carcinoma of salivary glands Aims: This study aimed to describe the expression oestrogen (ER)α, ERβ and aromatase gland (ACC). Methods results: ERα, was analysed by immunohistochemistry tissue microarray blocks from 38 cases ACC seven normal glands. The intracellular localization amount total protein were...
Canalicular adenoma (CA) is an uncommon benign salivary gland tumor that mostly occurs in the upper lip. Despite its nature, some patients may present multiple nodules and also microscopic growth can be multifocal with foci of within adjacent gland. Microscopically, CA mistaken for a polymorphous low-grade adenocarcinoma (PLGA) or basal cell (BCA), immunohistochemistry helpful differentiating them. Two cases canalicular showing are described. Both occurred lip white females aged 72 79 years....
