Lipid profile of people with Diabetes mellitus type 2 and periodontal disease

The objective of this study was to evaluate improvement of lipids and periodontal disease in patients with type 2 Diabetes mellitus, by means of the relationship between blood levels of total cholesterol and its fractions, triglycerides and clinical periodontal parameters. Twenty patients, in age-range 18-70 years, were selected and divided into 2 groups: (1) conventional periodontal scaling and root planing + controlled mechanic; (2) conventional periodontal scaling and root planing + controlled mechanical + maintenance therapy. The analyses were performed on day 0, 180 and 720 days, including plaque index, gingival index, probing depth and clinical attachment level, and evaluation of total cholesterol and its fractions, and triglycerides. The 2 groups presented significant reduction in clinical periodontal parameters, however, probing depth did not diminish significantly only in Group 1. There was significant improvement in all blood parameters in both groups. It was concluded that after 720 days of the experiment, there were significant improvements in clinical and blood parameters, in general. The group that received maintenance therapy also showed a more expressive improvement in clinical periodontal parameters, in general, suggesting that this therapy is important and necessary in patients with type 2 Diabetes mellitus and periodontal disease.

Accuracy of Digital Images in the Detection of Marginal Micro leakage: An In Vitro Study

Purpose: To evaluate the accuracy of Image Tool Software 3.0 (ITS 3.0) to detect marginal microleakage using the stereomicroscope as the validation criterion and ITS 3.0 as the tool under study.Materials and Methods: Class V cavities were prepared at the cementoenamel junction of 61 bovine incisors, and 53 halves of them were used. Using the stereomicroscope, microleakage was classified dichotomously: presence or absence. Next, ITS 3.0 was used to obtain measurements of the microleakage, so that 0.75 was taken as the cut-off point, and values equal to or greater than 0.75 indicated its presence, while values between 0.00 and 0.75 indicated its absence. Sensitivity and specificity were calculated by point and given as 95% confidence interval (95% CI).Results: The accuracy of the ITS 3.0 was verified with a sensitivity of 0.95 (95% CI: 0.89 to 1.00) and a specificity of 0.92 (95% CI: 0.84 to 0.99).Conclusion: Digital diagnosis of marginal microleakage using ITS 3.0 was sensitive and specific.

Efficacy of dip slide test for mutans streptococci in caries risk assessment

The aim of this study was to evaluate the efficacy of a dip slide test for mutans streptococci in caries risk assessment, when the microbiological results were compared to well-defined clinical criteria (DCC) for caries risk, clinically measured through high and low caries activity. Eighty-one volunteers from the 6(th) to 8(th) grades from public schools of Piracicaba, São Paulo, Brazil, were evaluated for dental caries. All free smooth surfaces were evaluated to check whether or not there were white spots. Based on the subjects' caries experience, a calibrated clinician divided them into groups of high and low caries activity. The subjects were submitted to a salivary test (CARITEST SM (R)) from the same batch number. Kappa statistics (kappa) were applied to verify the reproducibility of the simplified test, checked through interexaminer agreement when the results were classified by independent and blind means. The microbiological results were validated according to expressions of sensitivity and specificity. A moderate agreement was verified as the results were classified according to 6 scores (kappa =0.55), and the agreement was substantial when the results were classified according to high and low microbiological count (kappa =0.78). The sensitivity and specificity values were 0.59 and 0.85, respectively, showing that the test was more specific than sensitive, and could thus better identify the low caries risk subjects.

Biossegurança e odontologia: crenças e atitudes de graduandos sobre o controle da infecção cruzada

Este estudo teve o objetivo de investigar as percepções de graduandos de Odontologia sobre a fidelidade às diretrizes de biossegurança e acerca do preservar-se. Nove questões abertas, que abordaram aspectos de interesse para o tema, foram aplicadas em entrevista com 14 acadêmicos, que realizavam atendimento odontológico de pacientes da Faculdade de Odontologia de Araraquara da Unesp. Utilizou-se a metodologia de pesquisa qualitativa e a estratégia metodológica para análise das entrevistas foi a Discurso do Sujeito Coletivo (DSC). Três figuras metodológicas foram obtidas, sendo ideias-centrais, expressões-chave e o DSC propriamente dito. A análise dos discursos permitiu avaliar a fala natural da coletividade. Verificou-se a adesão dos entrevistados aos protocolos de biossegurança, embora houvesse a queixa de que, na rotina diária, as precauções fossem negligenciadas por não serem muito práticas. Entre as medidas de proteção individual e coletiva, rotineiramente utilizadas, foram apontados o uso de Equipamento de Proteção Individual (EPI) e as barreiras protetoras, bem como as atividades de desinfecção e esterilização. O risco de contágio foi visto por alguns com pavor e por outros com total indiferença porque acreditavam ser algo do qual é possível de se ter controle por meio da adesão às precauções padrão. Entre as doenças de maior preocupação, a aids e as hepatites B e C foram as mais temidas. Diante do discurso obtido, salienta-se a necessidade de se aperfeiçoar as estratégias educacionais, com intuito de motivar a fiel adesão às normas de biossegurança, essenciais no trato de pacientes odontológicos.
