Aggregatibacter actinomycetemcomitans em pacientes com síndrome de down: influência da condição periodontal e higiene bucal

Patients with Down syndrome have varying degrees of mental retardation, physical and motor, and apparently are more susceptible to infectious diseases. Thus, the present study aimed to evaluate the occurrence of Aggregatibacter actinomycetemcomitans in saliva and subgingival biofilms and above of children and adolescents with Down syndrome and analyze the influence of diet, socioeconomic and cultural factors and periodontal condition. After assessing the socio-economic and behavioral, were collected clinical specimens, which were transported to the laboratory of Microbiology and Immunology FOA-UNESP for detection of microorganisms by molecular method and periodontal conditions were evaluated according to the Periodontal Screening Index and Recording. The control group consisted of individuals without the syndrome. The results were analyzed by chi-square test for proportion analysis of variables with three or more categories, or the Mann-Whitney test. The data analysis of this study showed that the occurrence of A. actinomycetemcomitans ranged from 0.0% to 25.0%, both in the group of patients with Down syndrome, as for the control group and this was not affected by socioeconomic characteristics of the target population, either by oral hygiene standards

Carcinoma escamoso oral: análise retrospectiva de 185 casos

The squamous cell carcinoma is the most common malignancy in the oral cavity, representing over 90% of cancers in this region. This study aimed to conduct an epidemiological study of oral squamous carcinoma cases diagnosed by the Department of Pathology, Department of Pathology and Clinical Propaedeutics in the Dentistry Faculty of Araçatuba - UNESP, in the period between 1995 and 2005. 185 cases were studied, it was observed that the oral floor and tongue were the sites most affected, with predominance in males, white race and aged between 41 and 60 years, noting that the majority of patients were smokers. Knowledge of these data is important for the dental surgeon to act preventively, contributing to early diagnosis of cancer.

Fatores envolvidos no comportamento em higiene bucal e hábitos alimentares de crianças: revisão de literatura

The family is primarily responsible for shaping behavior in oral hygiene and nutrition of children, and cultural and psychosocial factors can influence this process. Thus, we carried out this study with the aim of presenting evidence from the literature on the subject. We reviewed the databases Bireme, Pubmed and Medline without restriction of year of publication. Used as descriptors "education," "care," "behavior," "oral health" and "food habits". We emphasize the responsibility of the family practices, values and beliefs of oral health and nutrition as well as the importance of shared care between family and professionals.

Biofilmes orais como um possível fator de risco ao câncer bucal

Introduction: much studies regarding risk factors associated with oral cancer. Factors such as smoking and alcohol and solar radiation are well established, but others, such as bacterial influence in the development or progression of a tumor still remain unexplained. Interest in the possible relationship between bacteria and different stages of cancer development has increased since the classification of H. pylori by the WHO as a definite carcinogen. Subsequently, links between infection and the onset of cancer in various sites in the body were discovered. Review of literature: this literature review attempts to show the influence of poor oral hygiene, with consequent bacterial accumulation as a possible important risk factor for the initiation and development of mouth cancer, and correlate the possible mechanisms by which bacteria can initiate or promote carcinogenesis. Conclusion: there is much evidence that bacteria in the oral cavity and periodontopathic are present in tumor tissue, however, still can not affirm that these bacteria initiate or promote carcinogenesis.

Estudo comparativo da expressão da survivina na citologia esfoliativa da mucosa bucal de pacientes com carcinoma de células escamosas intra-bucal e fumantes crônicos

Survivin protein is an inhibitor of apoptosis that plays a role in cell cycle control and the mechanism of carcinogenesis. The aim of this study was to verify the clinic pathological correlation of survivin expression in exfoliative cytology of chronic smokers, mucosa of patients with intra-oral squamous cell carcinoma (OSCC) and also from mucosa after surgical removal of OSCC. Patients were divided in 03 groups: Group 1: 26 patients who smoked more than 20 cigarettes/day/10years with no history of oral malignant neoplasm, or any clinical sign visible at examination. Group 2: 26 patients who had OSCC and Group 3: 22 patients surgically treated of OSCC for at least 01 month. Immunohistochemistry of the smears from each group was analyzed by light microscopy to extent and intensity of survivin positive cells. Survivin expression was observed in 100% of cases in group 1, 88.5% in group 2 and 100% in group 3. Groups 1 and 3 showed cytoplasmic expression in 100% of the cases, while group 2 showed it in 87.5%. Cytoplasmic and nuclear expression was 7.69% observed only in group 2. The results were association with clinicopathological data by Fisher's exact test and it was significant to smoke cessation in group 2 on intensity (p=0.015) of survivin expression. The intensity of survivin expression was related to smoking cessation in group 2. Smoking history (pack/years) showed no influence survivin expression

Avaliação da atividade antifúngica de peptídeos derivados da histatina-5 para o tratamento de candidose bucal

Os peptídeos têm sido amplamente estudados e demonstrados como uma estratégia promissora no combate a micro-organismos patogênicos, devido aos inovadores mecanismos de ação que apresentam e a menor indução de resistência nos microorganismos. Os peptídeos da família das Histatinas, naturalmente presentes na saliva humana, são os principais agentes que auxiliam na cicatrização e oclusão de feridas, re-epitelização e, além disso, dispõem de mecanismos de ação contra microorganismos, em especial, a Candida albicans. O agente etiológico da Candidiose bucal é a Candida albicans, um patógeno de origem fúngica, que acomete indivíduos de todas as idades, indivíduos imunologicamente debilitados e, especialmente, os usuários de próteses dentárias. Um importante fator de virulência da Candida albicans é a habilidade de formar biofilmes, estrutura comunitária microbiana revestida por exopolissacarídeos, capaz de aderir-se a superfícies lisas. Os biofilmes associam-se com a capacidade de causar infecções, com o desenvolvimento de resistência contra o sistema imune do hospedeiro e contra os antifúngicos. O uso indiscriminado e a exposição prolongada aos antifúngicos induz o surgimento de resistência a esses medicamentos, além disso existem cepas de Candida albicans resistentes ao tratamento com antifúngicos azólicos. Devido a isso surge a necessidade de desenvolvimento de novos alvos terapêuticos. O objetivo desse estudo consiste no desenvolvimento de análogos da Histatina-5 com algumas modificações estruturais, a fim de potencializar a ação terapêutica já comprovada dos peptídeos da família das Histatinas. A Histatina-5GH apresenta maior carga positiva que os demais peptídeos devido a troca de duas glicinas na estrutura da Histatina-5 por duas histidinas. Por sua vez, a Histatina-5SC possui o resíduo de serina C-terminal substituído por...
