Anatomical variation of the maxillary sinus in cone beam computed tomography.

Purpose. The aim of this paper is to report a case in which the cone beam computed tomography (CBCT) was important for the confirmation of the presence of maxillary sinus septum and, therefore, the absence of a suspected pathologic process. Case Description. A 27-year-old male patient was referred for the assessment of a panoramic radiograph displaying a radiolucent area with radiopaque border located in the apical region of the left upper premolars. The provisional diagnosis was either anatomical variation of the maxillary sinuses or a bony lesion. Conclusion. The CBCT was important for an accurate assessment and further confirmation of the presence of maxillary septum, avoiding unnecessary surgical explorations.

Periodontal disease and diabetes mellitus.

UNLABELLED: Periodontal disease (PD) is one of the most commonly known human chronic disorders. The relationship between PD and several systemic diseases such as diabetes mellitus (DM) has been increasingly recognized over the past decades. OBJECTIVE: The purpose of this review is to provide the reader with knowledge concerning the relationship between PD and DM. Many articles have been published in the English and Portuguese literature over the last 50 years examining the relationship between these two chronic diseases. Data interpretation is often confounded by varying definitions of DM, PD and different clinical criteria were applied to determine the prevalence, extent and severity of PD, levels of glycemic control and diabetes-related complications. METHODS: This paper provides a broad overview of the predominant findings from research conducted using the BBO (Bibliografia Brasileira de Odontologia), MEDLINE, LILACS and PubMed for Controlled Trials databases, in English and Portuguese languages published from 1960 to October 2012. Primary research reports on investigations of relationships between DM/DM control, PD/periodontal treatment and PD/DM/diabetes-related complications identified relevant papers and meta-analyses published in this period. RESULTS: This paper describes the relationship between PD and DM and answers the following questions: 1- The effect of DM on PD, 2- The effects of glycemic control on PD and 3- The effects of PD on glycemic control and on diabetes-related complications. CONCLUSIONS: The scientific evidence reviewed supports diabetes having an adverse effect on periodontal health and PD having an adverse effect on glycemic control and on diabetes-related complications. Further research is needed to clarify these relationships and larger, prospective, controlled trials with ethnically diverse populations are warranted to establish that treating PD can positively influence glycemic control and possibly reduce the burden of diabetes-related complications.

Manifestaciones bucales del pénfigo vulgar: consideraciones generales y reporte de caso clínico / Oral manifestations of pemphigus vulgaris: general considerations and clinical case report

El pénfigo vulgar es una enfermedad vesículobulbosa de la piel y de las membranas mucosas caracterizada por la presencia de auto-anticuerpos contra moléculas de la adhesión intraepidérmicas. Es una condición poco usual, capaz de provocar señales y síntomas que varían de leve a moderado, pudiendo muchas veces, exigir controles terapéuticos prolongados para toda la vida del paciente. Su etiología permanece oscura, pero se sabe que poseen etiopatogenia de carácter inmunológico. El objetivo del presente artículo es presentar un caso clínico de manifestaciones bucales de Pénfigo Vulgar, donde se buscó hacer consideraciones generales sobre la importancia del odontólogo en relación a las conductas frente a los pacientes con sospecha de ser portadores de esta patología.

Pemphigus vulgaris is an autoimmune blistering disease of the skin and mucous membranes characterized by the presence of autoantibodies against intra-epidermal adhesion molecules. It is an uncommon condition and it is able to produce from mild to severe sigh and symptoms, and sometimes may be lifethreatening. Its etiology is still obscure, but it is known to be an immunological condition. The aim of this paper is to report a case of bucal manifestations of pemphigus vulgaris, regarding important general considerations to the dentist in what is concerned to the pemphigus vulgaris patients.

Comparison of halitosis parameters and sialometry between patients subjected to head and neck radiotherapy and patients with periodontal disease

The aim of this study was to evaluate halitosis parameters and sialometry in patients subjectedto head and neck radiotherapy compared to patients with periodontal disease, establishing arelationship between oral concentration of volatile sulfur compounds (VSCs) and tongue coatingpresence, salivary flow rate and BANATM test. Methods: Thirty-eight patients were examinedand divided into 2 groups: group I: patients with chronic generalized periodontal disease previouslydiagnosed and not treated; group II: patients subjected to head and neck radiotherapy. All volunteerswere subjected to halitosis measurements through a sulphide monitor, evaluation of tongue coatingweight, stimulated and non-stimulated sialometry and BANATM test. Results: The results wereanalyzed by analysis of the variance, Pearson’s correlation coefficient and Student’s t-test, showingthat both groups presented halitosis. There was also a relationship between tongue coatingpresence and VSC levels in both groups and the irradiated patients showed lower salivary flowrates. Conclusions: Under the tested conditions, it may be concluded that halitosis can beconsidered as an adverse effect of radiotherapy, associated with low salivary flow and poor oralhealth, which seems to be the main contribution to bad breath, since patients with periodontaldisease also showed halitosis.

Saliva and tongue coating pH before and after use of mouthwashes and relationship with parameters of halitosis.

OBJECTIVES: The aim of this work was to evaluate saliva and tongue coating pH in oral healthy patients with morning bad breath before and after use of different oral mouthrinses. MATERIAL AND METHODS: Saliva and tongue coating pH of 50 patients allocated in 5 groups were measured respectively by a digital pHmeter and color pH indicators, before, immediately after and 30 min after rinsing 5 different mouthrinses: cetilpiridine chloride associated with sodium chloride, triclosan, enzymatic solution, essential oil and distilled water. RESULTS: Only triclosan and essential oil increased salivary pH immediately after rising. The enzymatic solution decreased salivary and tongue coating pH immediately after rinsing. CONCLUSIONS: Salivary pH tended to be acidic while tongue coating pH tended to be alkaline, even after rising. Triclosan and essential oil mouthrinses increased salivary pH immediately after rinsing. Enzymatic solution decreased saliva and tongue coating pH immediately after rising.

Larva migrans in the oral mucosa: report of two cases.

Cutaneous Larva migrans is a very common disease in tropical regions. In the oral mucosa, the infection occurs in the same way as in the skin, but it is rarer. This report describes two cases of Larva migrans in the oral mucosa. The first case was in a 27-year-old woman who presented an erythematous plaque located on the buccal mucosa, extending to a posterior direction, following a linear pattern, to other areas of the mouth. After incisional biopsy of the anterior-most portion of the lesion, morphological details obtained in multiple examined sections suggested Necator or Ancylostoma braziliense larvae as the cause of infection. The second case was in a 35-year-old male who presented a fusiform erythematous plaque in the palatal mucosa. This area was removed and submitted to microscopic examination under a presumptive diagnosis of "parasite migratory stomatitis". The histological characteristics were suggestive of a larva pathway. In both cases the lesion disappeared after biopsy and the patients were symptom-free.

Larva migrans cutânea é uma doença muito comum em regiões tropicais. Na mucosa oral, a infecção ocorre da mesma forma como na pele, mas é raro. Este relato descreve dois casos de Larva migrans na mucosa oral. O primeiro caso foi de uma mulher de 27 anos de idade, que apresentou uma placa eritematosa localizada na mucosa julgal, estendendo-se posteriormente, em conformação linear, para outras áreas da boca. Após biópsia incisional da porção mais anterior da lesão, detalhes morfológicos obtidos em múltiplos cortes examinados sugeriram Necator ou larvas de Ancylostoma braziliense como a causa da infecção. O segundo caso foi de um homem de 35 anos de idade que apresentou uma placa fusiformes eritematosas na mucosa palatina. Esta área foi removida e submetida a exame microscópico, com diagnóstico presuntivo de "estomatite migratória por parasita". As características histológicas foram sugestivas de trajeto de larva. Em ambos os casos a lesão desapareceu após a biópsia e os pacientes estavam assintomáticos.

Avaliação da aceitação de pacientes em relação ao uso de antissépticos orais e estudo do pH das diferentes soluções / Evaluation of patients' acceptance of mouthwashes use and pH study of different solutions

O objetivo deste estudo foi avaliar o pH de diferentes antissépticos orais e as opiniões dos pacientes em relação ao enxaguante utilizado. Cinquenta pacientes realizaram bochechos com cinco diferentes soluções – clorito de cetilpiridínio associado ao cloreto de sódio, triclosan, solução enzimática, óleo essencial e água destilada.Os pacientes foram submetidos a um exame clínico, bochecho específico e aplicação do questionário. Pôde-se observar que as quatro marcas comerciais de soluções para bochecho testadas apresentaram pH ácido e que houve diferença entre as medidas entre os pHmetros analógico e digital. Os enxaguantes de maior aceitação foram o dióxido de cloro e solução enzimática.

Atypical lesion on soft palate: a curious case / Lesión atípica en el paladar blando: relato de caso

The aim of this work is to present a case of a 39-years-old man with a 2cm sized purple pedunculated tissue on the soft palate, next to upper right retromolar area, asymptomatic, with one day time evolution and vascular appearance. There was no trauma history or systemic diseases. Based on the clinical findings our previous diagnosis was traumatic granuloma, hemangioma or blood coagulum formation after local trauma. After one week, intraoral examination revealed absence of the lesion, which disappeared completely. This case illustrates that the absence of trauma history and atypical clinical characteristics can be a diagnostic defiance in the clinical routine.

Luego de una semana, el examen intraoral reveló ausencia de la lesión, la que desapareció por completo. Este caso ilustra que la ausencia de historia de trauma y las características clínicas atípicas, puede ser un desafío diagnóstico en la rutina clínica.

Manifestações bucais da paracoccidioidomicose: considerações gerais e relato de caso / Oral manifestations of paracoccidioidomycosis: general considerations and case report

A paracoccidioidomicose é uma doença sistêmica que envolve primariamente, os pulmões e, posteriormente, dissemina-se para outros órgãos e sistemas. Lesões secundárias aparecem frequentemente nas membranas mucosas, linfonodos e pele. Tanto a apresentação clínica dessa micose quanto o curso da doença variam para cada paciente. Infecções subclínicas tem sido documentadas em pessoas saudáveis residentes em áreas endêmicas. Essas áreas estão confinadas a alguns países da América Latina. A paracoccidioidomicose é frequentemende diagnosticada no Brasil, Venezuela, Colômbia, Equador e Argentina. No Brasil a doença constitui um importante problema de saúde pública. O agente etiológico da doença é um fungo dismórfico, o Paracoccidioides brasiliensis. A abordagem clínica de pacientes portadores de lesões ulceradas crônicas na boca deve considerar a paracoccidioidomicose como possibilidade diagnóstica. Este trabalho apresenta uma revisão de literatura sobre essa doença, abordando aspectos clínicos, epidemiologia, métodos diagnósticos e de tratamento, além de relatar um caso diagnosticado após avaliação clínica, citologia esfoliativa e biópsia incisional

Comparison of radiographic measurements obtained with conventional and indirect digital imaging during endodontic treatment.

The aims of this study were to evaluate the quality of indirect digitized radiographic images taken during endodontic procedures and to compare the measurements recorded with this technique to those obtained from conventional radiographs. Two-hundred conventional periapical radiographs taken at the undergraduate Endodontics Clinic of the Dental School of Bauru were digitized. The conventional and indirect digitized images were compared by three examiners as to the quality and accuracy of the measurements recorded during endodontic treatment, in canal length determination, gutta-percha adaptation, lateral condensation and final obturation. The conventional radiographs were observed on a film viewer, surrounded by a dark card, and measured with magnifying glass and a millimeter ruler; the indirect digitized images were evaluated on the Digora for Windows software, with free utilization of the bright/contrast tool. Unlike the conventional radiographic images, all indirect digitized images were considered as having a high quality. The distance between the filling material and the root apex was 0.117 mm larger, on average, for the Digora system (p<0.01). The measurements achieved by the investigated radiographic methods were clinically similar and they are thus equivalent. Changes in brightness and contrast of the images using Digora software improved the diagnosis.

Principais mecanismos de atuação do álcool no desenvolvimento do câncer oral / Main alcohol performance mechanisms in the oral cancer development

O Efeito do álcool sem associação ao tabaco vem sendo estudado; contudo, os mecanismos pelos quais o álcool exerce o seu efeito carcinogênico não estão completamente esclarecidos. Evidências sugerem que o efeito do álcool esteja relacionado principalmente à exposição tópica, que altera membranas celulares e aumenta a permeabilidade ao tabaco. É proposto também que o efeito do álcool seja modulado por polimorfismos de genes que codificam enzimas para o metabolismo do etanol, do folato e reparo do DNA. O mecanismo de atuação do álcool também está realcionado a um efeito genotóxico do acetaldeído, o principal metabólito do etanol, alteração no metabolismo dos retinóides, deficiências nutricionais e efeitos sistêmicos. Porém, há uma grande dificuldade na avaliação do efeito do álcool, devido à falta de exatidão das histórias do consumo, dos tipos de bebidas, suas concentrações e quantidades, alterando os resultados dos estudos. Este trabalho se propõe a discutir os principais mecanismos de atuação do álcool que poderão promover o desenvolvimento do câncer oral, e nortear o cirurgião-dentista quanto à sua prevenção.

The chronic and excessive alcohol intake is associated with an increased risk for developing oran cancer, which has tobacco and alcohol as risks factors. Nevertheless, the sole effect of alcohol, not associated with tobacco has been related to the development of oral cancer. However, the exact mechanism by which alcohol may exert this effect is not clear. Evidence suggests that the effect of alcohol is related, mainly, to the topic exposure, which promotes modifications in cell membranes and increase in the permeability for carcinogenic agents, such as tobacco. It has also been suggested that the effect of alcohol is modulated by polymorphisms in genes encoding enzymes for ethanol metabolism, folate metabolism and DNA repair. The mechanism of alcohol performance is related to the existence of acetaldehyde genotoxic effect, changes in retinoid metabolism, nutritional deficiencies and systemic effects. Yet, there still exists a vast difficulty in evaluating the alcohol effect, mainly due to the lack of exactness description of alcohol consumption, type of alcoholic beverages, concentration and amount of alcohol, which, therefore, disturb the study data. This study aims at explaining the main mechanisms by which alcohol acts in developing oral cancer, and guiding the general dentist to prevent this cases.

Evaluation of oral and nasal halitosis parameters in patients with repaired cleft lip and/or palate.

OBJECTIVE: The objective of this study was to investigate the relationship between halitosis parameters in patients with and without cleft lip and/or palate. STUDY DESIGN: Forty-two subjects were examined. They were divided into group I, postgraduate students of Bauru Dental School (FOB); and group II, individuals with repaired cleft lip and/or palate. The concentration of volatile sulfur compounds (VSC) was assessed with a portable sulfide monitor and the values were correlated to the salivary flow rate and weight of tongue coating. RESULTS: There was a relationship between the presence of tongue coating and VSC levels, as well as between salivary flow rate and VSC levels in group II. The same group also revealed a significant correlation between weight of tongue coating and salivary flow rate. There were no significant differences between groups as regards the Halimeter oral measurement. CONCLUSIONS: Individuals with repaired cleft lip and/or palate can have the same VSC levels as subjects without clefts.

Oral health of building construction workers: an epidemiological approach

Este estudo transversal foi delineado para avaliar as condições de saúde bucal de trabalhadores da construção civil em município da região centro-oeste do Estado de São Paulo. Foram examinados 219 indivíduos do sexo masculino, com idades entre 17 e 72 anos. O levantamento das condições bucais foi realizado em processo de amostragem aleatória simples, a partir do total de 450 inscritos na MEGA-SIPAT 2000 (Semana Interna de Prevenção de Acidentes do Trabalho). Foi utilizado o índice CPOD (cárie dentária) e necessidade de tratamento odontológico, segundo metodologia proposta pela Organização Mundial da Saúde (1997). Neste estudo, são descritas a prevalência de cárie segundo a idade, ocupação e escolaridade. Entre os 219 trabalhadores examinados, o valor CPOD apurado foi 16,9. Os trabalhadores mais jovens (<25 anos de idade) apresentaram média de 21,3 dentes sem necessidade de tratamento, enquanto os mais velhos mostraram necessidades progressivas de tratamento restaurador e reabilitador (p<0,001). Verificou-se índice CPOD de 15,6 para os trabalhadores de áreas administrativas e 21,7 para os mestres-de-obras, sem significância estatística. Houve aumento do índice CPOD segundo a idade, para todos os grupos de trabalhadores (p<0,001). A necessidade de tratamento auto-referida mostrou-se associada a valores CPOD mais baixos para os indivíduos que relataram resposta positiva, quando comparado àqueles que não apresentavam percepção de tais necessidades (p<0,05). Estas diferenças foram significantes, à análise de variância e teste t de Student. Para os trabalhadores da construção civil, neste estudo, não foram observadas lesões orais importantes, presentes em apenas 2,7% dos indivíduos, apesar da exposição diária a alguns fatores de risco para câncer de boca.
