Aim: to evaluate the association of the long face pattern and the mouth breathing, correlating them with the intraoral characteristics. Methods: the sample was composed of 60 Caucasian Brazilian descendents patients, divided in two groups according to the subjective of their facial pattern. The patients were clinically evaluated to determine their respiratory pattern and the diagnosed of malocclusion. The lateral teleradiographies were drawn in standard to verification facial cephalometric pattern. Chi-Square analysis evaluated the association between subjective facial pattern and type of breathing; facial pattern subjective and cephalometric facial pattern. It was also the chi-square with yates correction to evaluate the associations between subjective facial pattern, type of breathing and posterior cross bite; facial subjective standard, type of breathing and anterior open bite; facial pattern between subjective, type breathing and type of Angle´s malocclusion. Results: it showed that long face pattern (group 1) was associated with mouth breathing habit and facial cephalometric standard. Moreover, the long-face pattern (group 1) presented that mouth breathing was associated with a posterior crossbite and Angle Class II malocclusion. Conclusion: the long face pattern - evaluated with subjective facial analyses - was associated with mouth breathing. The long face pattern and patients with mouth breathing was associated with a posterior crossbite and Class II Angle's malocclusion.

Objetivo: Estimar as probabilidades acumuladas de sobrevida dos pacientes diagnosticados com carcinoma espinocelular nos 10 primeiros anos do Centro de Oncologia Bucal da UNESP, Campus de Araçatuba, de 1991 a 2000, observadas até 2005, estabelecendo os possíveis fatores prognósticos significativos para o óbito. Méttodo: A análise de sobrevida foi realizada em uma coorte de 280 pacientes com carcinoma espinocelular, no Centro de Oncologia Bucal da Faculdade de Odontologia de Araçatuba, UNESP, entre 1991 e 2000. Para avaliar a associação entre as variáveis independentes e o óbito, realizou-se o teste Log Rank. A probabilidade do teste com p-valor menor que 0,25 ficou estabelecida para a inclusão das covariáveis no processo de ajustamento do modelo. A sobrevida foi estimada pelo método de produto limite de Kaplan-Meier. Os fatores prognósticos foram estimados pelo modelo de riscos proporcionais de Cox, calculando-se razão da função de risco (HR). A análise de resíduo foi realizada para verificar o ajuste do modelo. Resultados: As taxas de probabilidades acumuladas de sobrevida de 280 pacientes, para os casos em estádio IV, foram, 56,74%, 32,13%, 23,71% e 20,57%, respectivamente, até 1, 2, 3 e 5 anos após o diagnóstico. Pacientes no estádio I apresentaram sobrevida em 5 anos de 81,73%. O estadiamento clínico da doença no diagnóstico foi o único fator prognóstico definido no processo de ajuste de modelo. A estimativa da razão da função de riscos de morrer em pacientes diagnosticados no estádio III (HR=3,3), é praticamente três vezes o risco daqueles em estádio I; da mesma forma, o risco de morrer dos diagnosticados em estádio IV (HR=6,17) é cerca de seis vezes ao daqueles em estádio I. Conclusões: A covariável que permaneceu no modelo final foi estadiamento clínico no momento do diagnóstico, sendo, pois, o único fator prognóstico.

A presença de doenças sistêmicas, uso de medicamentos, e uso de próteses removíveis, entre outros fatores, podem alterar o equilíbrio fisiológico da cavidade bucal favorecendo o estabelecimento de diversas alterações e/ou patologias bucais. Assim, o estudo das prevalências destes fatores, nos pacientes odontológicos, tornam-se importantes pois devem ser considerados para elaborar o diagnóstico e definir a conduta terapêutica. Com o objetivo de delinear um perfil, avaliamos os prontuários de 500 usuários de próteses removíveis atendidos no Serviço de Medicina Bucal da Faculdade de Odontologia de Araraquara - UNESP. Analisamos os dados referentes a: características da população e das próteses removíveis, prevalência das doenças sistêmicas, uso de medicamentos e diagnóstico final das patologias ou alterações bucais. Os resultados obtidos nos permitem concluir que a maioria (74%) dos usuários de próteses removíveis eram mulheres brancas; metade da população pertencia a faixa etária de 41 a 60 anos e, quase a metade (49,2%) usava a combinação de prótese total superior e inferior. As doenças sistêmicas foram relatadas por 57,2% da amostra e a prevalência maior foi de doenças do sistema cardiovascular (25,4%). A maioria (60,4%) da população relatou uso de medicamentos e, dentre os mais freqüentes, a prevalência maior foram dos cardiovasculares (26,4%). A prevalência de patologias ou alterações bucais foi de 99,6%, sendo as relacionadas ao uso de próteses removíveis as mais freqüentes. Dentre estas, a candidose crônica atrófica ocorreu em 81,8% da população estudada e a hiperplasia fibrosa em 29,2%.

A redução da dose de radiação ao paciente é aceita em Radiologia Odontológica, com a finalidade de diminuir os riscos associados ao exame radiográfico. Para atingir este objetivo, além do avanço tecnológico ocorrido nas últimas décadas, devemos considerar a importância do Critério de Seleção para o paciente e da prescrição radiográfica na indicação correta do tipo de radiografia necessária para cada um deles. O objetivo deste trabalho foi avaliar a prescrição radiográfica de pacientes atendidos pelo Serviço de Medicina Bucal da Faculdade de Odontologia de Araraquara - UNESP durante o período de 1989 a 1993. Selecionamos 396 prontuários que constituiu a totalidade dos que continham exames radiográficos. Para a análise da prescrição radiográfica, consideramos as informações obtidas da ficha clínica e da interpretação das radiografias, utilizando os Critérios de Seleção e a análise de decisão clínica. Os resultados demonstraram um alto índice de pacientes com prescrição incorreta (44,0%); tendo em 24,7% dos pacientes ocorrido mais de uma radiografia prescrita incorretamente. Com relação ao tipo de técnica com prescrição incorreta, em 31,6% dos pacientes foi realizada a radiografia panorâmica, vindo a seguir a oclusal (28,7%), outro (17,2%) e a associação da panorâmica e oclusal (12,6%). Pacientes portadores de doenças e alterações de tecido mole tiveram a mais alta freqüência de prescrições incorretas, seguidos pelos portadores de doenças das glândulas salivares (13,5%) (incluindo os tumores); outros (10,1%); distúrbios da A.T.M. (9,0%); inflamação e infecção dos maxilares (6,8%); tumores benignos (5,6%) e tumores malignos (5,6%). Em 62,9% dos pacientes, o exame radiográfico contribuiu para o diagnóstico e tratamento. A alta porcentagem de prescrição incorreta encontrada evidencia a necessidade de... (Resumo completo, clicar acesso eletrônico abaixo).

The Health Sciences, prior to the planning of prevention programs, adopt the tools to analyze the population profile, entitled epidemiological surveys, to obtain data on the need for heathcare and the possibility of treating health events. The aim of this study was to evaluate dental conditions in schoolchildren, aged five to fourteen, enrolled in public schools in Américo Brasiliense, SP Brazil. The dmft and DMFT index, caries experience, and prevalence of fluorosis were analyzed. For this epidemiological study, 1,137 children were selected. Four calibrated dentists performed oral exams according to WHO criteria (1997). The data were collected using descriptive analyses. The results showed that 94% of the five-year-old children were caries free, and the value of dmft was 1.44. DMFT was 1.19 in 12-year-olds. The lowest and the highest fluorosis prevalence could be observed in eight and fourteen-year-olds, respectively. It could be concluded that the city of Américo Brasiliense has developed respectful educational and preventive oral health programs which presented satiosfactory results in the present epidemiological study.

The burning mouth syndrome (BMS) is a relevant pathology that has been defined as a chronic pain with difficult diagnosis and treatment. The prevalence of BMS is estimate to be 15% of the general population, being more common in the elderly and middle-aged. Characterized by a burning sensation in more than one area, more frequently on the two thirds of the tongue, on the anterior half of the hard palate and on the mucosa of the upper lip, the BMS is associated with clinical signs of normality and normal laboratory findings. For several studies the BMS etiology is controversial because it is multifactorial since it can be caused by local, neuropathic, psychological and/or systemic factors. These controversies make the diagnosis more difficult, especially if the dentist does not have knowledge about the syndrome. Thus, the aim of this paper is to present, by means of a literature review, the main features of BMS, indicating the procedures that may be useful for diagnosis, and also the available therapeutic modalities in order to increasing the knowledge of health professionals so that patients with BMS may benefit from appropriate treatment, support and professional confidence, always aiming to better quality of life.

The ability to tridimensionally evaluate pathological and anatomical areas, in apical surgery planning, presents a number of advantages. Cone beam computed tomography (CBCT) was developed for dental applications. This paper aims to present a literature review on CBCT, highlighting its advantages over both conventional computed tomography (CT) and radiography. Moreover, its clinical applications in apical surgery are discussed. LITERATURE REVIEW AND CONCLUSION: Unlikely CT, CBCT captures a volume of data in a single 360º rotation, providing benefits such as higher accuracy, better resolution, reduced scanning time and reduced radiation dose. In the maxillofacial region, CBCT has been mainly used in the assessment of dento-alveolar pathology and oral traumatology. CBCT provides a better diagnosis and quantitative information on periodontal bone levels than conventional radiography. It has also been used for patients requiring surgical facial reconstruction, orthognathic surgery, dental implants, and more complex tooth extractions. Besides that, it seems to be a significant tool in modern endodontic practice, presenting useful applications in apical surgery.

Introductions: A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. Its etiology is not fully understood. With regard to its prevalence, it occurs more commonly in permanent dentition and twice as often in men than in women. Supernumerary teeth are classified according to their morphology and location. Their presence can cause problems such as failure of eruption, displacement of teeth, crowding and odontogenic cysts and tumors. The diagnosis is usually by routine radiographs, for the majority of such teeth are impacted and asymptomatic. Objective and Case report: The purpose of this study was to make a brief review of the relevant literature and report one clinical case of the female patient, 23 years, melanoderma, featuring three quarters molars. Final considerations: The early diagnosis proved to be important for the resolution of the case in order to minimize or even prevent the development of complications and thus establish a proper plan of treatment.

Halitosis is the unpleasant odor of exhaust air through the mouth and lungs. There are over 50 causes, and approximately 90% of cases, is of oral origin. May have physiological origin (stress, breath of morning, fasting, and inappropriate diets), local reasons (bad oral hygiene, bacterial plaque retained on the tongue and/or tonsils, lower production of saliva, gum disease) or systemic reasons (diabetes, kidney or liver problems, constipation, etc.). In the Third Age, this problem tends to increase significantly. Thus, the aim of this study was to detect the presence of halitosis in the geriatric group attended in the dental clinic of UNIRP, identifying their incidence and principal causes. The sample consisted of 48 volunteer patients aged 60 years or older and included more than 90% of patients treated in this age group. It was performed a anamnesis and physical examination. The intra-oral halitosis was detected using a breath meter (halimeter). In the group studied, approximately 54.16% had halitosis, 84.61% of these were users of the prosthesis. The tongue coating was present in 80.76% of individuals with halitosis. After brushing the tongue, 88.46% of patients with halitosis have had the initial index oral malodor decreased. Based on the results of this study it was concluded that factors as dental prostheses and tongue coating are critical factors in causing halitosis.

The concepts of buccal health promotion and the increase of life expectancy have contributed for the highest maintenance of dental elements. Thus, with the new alimentary and behavioral habits the irreversible loss of dental hard tissue of non-carious origin has increased substantially, being divided in attrition, erosion and abrasion. The dental erosion is a chronic pathology defined as the superficial loss of dental hard tissue as a result of a chemical process not involving bacteria caused by acid that could be intrinsic, extrinsic or unknown etiology, causing irreversible loss of mineral tissue and dentinal hypersensitivity. The aim of this paper is to present a review of literature on the main factors that can cause the injuries of erosion, including the different aspects related to its etiology, classification, diagnosis, prevention and treatment.
