The length of obturation is related to the presence of apical peridontitis and consequently to the success of endodontic treatment.

We declare no confl ict of interest. ABSTRACT We evaluated the DMFT (decayed, missing and fi lled teeth) index and the prevalence of candidia-sis, linear gingival erythema, oral hairy leukoplakia, herpes simplex, aphthous ulcers, Kaposi's sar-coma and lymphoma, as well as the association with TCD4 count, viral load (VL) and antiretroviral therapy (ART) in 140 HIV-infected adult individuals. A standardized examination to determine the DMFT index and the presence of oral lesions was conducted. Demographic data, TCD4 count and use of ART were obtained from medical records. A high number of decayed teeth detected among patients undergoing ART resulted in a mean DMFT of 16.9 teeth. It was observed that 24.2% of the individuals had at least one oral lesion. Candidiasis was the most frequent lesion and was associated with the TCD4 count. Oral hairy leukoplakia was associated with an increased VL. Regular use of ART was inversely associated with the occurrence of lesions. Overall, the studied population showed low prevalence of oral lesions and high DMFT index. The use of ART seems to reduce the occurrence of these lesions. Higher TCD4 count and a lower VL were associated with an improved oral health status in HIV+ individuals.

Platelet count is associated with inflammatory diseases like diabetes mellitus (DM), which in turn, is related in a bidirectional manner with apical periodontitis and periodontal disease. The aim of this study was to evaluate the effects of apical periodontitis and/or periodontal disease on mean platelet count in a rat model of diabetes mellitus. Eighty Wistar rats were randomly divided into 8 groups (n=10): control (C), apical periodontitis (AP), periodontal disease (PD), apical periodontitis with periodontal disease (AP-PD), diabetes mellitus (DM), diabetes mellitus with apical periodontitis (DM-AP), diabetes mellitus with periodontal disease (DM-PD) and diabetes mellitus with apical periodontitis and periodontal disease (DM-AP-PD). Rats were anesthetized and DM was induced with a single dose of streptozotocin diluted in citrate buffer solution. After 6 days, the DM was confirmed. The animals were sedated and apical periodontitis was induced by dental exposure and periodontal disease was induced by periodontal ligature. After 30 days, animals were anesthetized and the blood was collected by cardiac puncture. Samples were processed and the mean platelet count was obtained. Data were tabulated and subjected to statistical analysis (p<0.05). Diabetic rats had higher mean glycemic levels compared with nondiabetic rats at 6 and 36 days after DM induction (p<0.05). The DM-PD and DM-PD-AP groups showed increased mean platelet count compared to control and AP groups (p<0.05). The periodontal disease alone or associated with apical periodontitis influence mean platelet count in a rat model of diabetes mellitus.

A halitose é um problema frequente na população em geral. Grande parcela dos indivíduos apresenta alguma forma de mau odor oral de maneira crônica com potenciais consequências sérias na vida pessoal e profissional. O presente estudo teve como objetivo avaliar a presença e interferência da halitose na qualidade de vida dos pacientes atendidos na clínica odontológico do Centro Universitário São Lucas, do município de Porto Velho-RO, além de realizar um levantamento buscando relacionar sua incidência a doenças sistêmicas presentes nessa amostra. Tendo como base uma população de 250 pessoas, foi avaliada uma amostra de 171 pacientes, que concordaram em responder o questionário estruturado, e em seguida realizar o teste de halimetria e avaliação de presença ou não de saburra lingual. Foram analisados, através do prontuário de cada paciente, o exame periodontal e antecedentes pessoais médicos e odontológicos. A idade média dos pacientes avaliados é de 34,4 anos do total da amostra. 27,5% apresentaram odor pesado; 43,9 apresentaram gengivite; 31% tinham periodontite, 56,7% acreditam ter mau hálito, sendo que 29,6% relataram algum tipo de prejuízo na sua vida social. Portanto a partir dos resultados obtidos pode verificar que existe uma forte relação da halitose com doenças bucais, comprometendo a convivência social desses pacientes.
