Two endodontics techniques analysis in primary molars with fistula

OBJECTIVE: The purpose of this research was to follow the radiolucent area (pixels) in the furcation area and the behavior of the endodontically treated deciduous molars with different simplified echniques.METHODS: The treatments were performed without the duct instrumentation using relative isolation and two drugs were applied, as follows: G1: Guedes-Pinto paste (GP) and G2: CTZ paste (CTZ) for the pulp chamber filling. The radiolucent areas in the furcation region of deciduous molars were obtained from previous x-rays, after 6 and 12 months of the endodontic treatment and was analysed by l Image Tool 3.0 by two blinded examiners. In order to analyse the calibration between the examiners, Kappa test was used and for comparison of the initial radiographic image, analysis of variance was used after 6 and 12 months of each group and Tukey spost-hoc test. T-Student test was used for comparison between groups.RESULTS: There was a reduction of radiolucent area after 6 (p<0.01) and 12 months (p<0.01) in the teeth treated with CTZ paste. In the teeth treated with PG there was not reduction of radiolucent area after 12 months. (p= 0,09).CONCLUSION: Although the clinical signs were similar in both groups after 12 months of follow up, only teeth treated with CTZ showed reduction of radiolucent area in the furca area after 6 and 12 months.

Doença periodontal e complicações obstétricas: há relação de risco?

Estudos tem apontado possiveis relacoes de risco existentes entre doencas bucais, principalmente a doenca periodontal, e complicacoes gestacionais, como parto prematuro, nascimento de recem-nascidos de baixo peso e pre-eclâmpsia. As explicacoes para tais hipoteses baseiam-se no fato de a doenca periodontal ser de origem infecciosa, o que poderia provocar aumento de citocinas inflamatorias no sangue materno, por liberacao direta da bolsa periodontal ou por disseminacao de bacterias patogenicas, induzindo sua producao sistemica. Esta suposicao fundamenta-se no conhecimento de que a fisiopatologia das complicacoes obstetricas citadas esta associada a presenca de algumas citocinas no sangue materno. O presente trabalho teve como objetivo realizar revisao da literatura em busca de evidencias para estas supostas associacoes. Apesar do grande numero de estudos clinicos encontrados nesta revisao, observa-se a falta de padronizacao metodologica dos mesmos, fato que limita conclusoes definitivas a respeito. Por outro lado, o fato de a doenca periodontal ainda nao ser comprovadamente um fator de risco para as complicacoes obstetricas nao diminui a importância da manutencao da saude bucal das gestantes, que devem apresentar condicoes orais que propiciem adequada alimentacao, sem dor e sangramento, e assim manter seu aporte nutricional adequado.Studies have shown possible risk relations among oral illnesses, mainly periodontal disease and adverse pregnancy outcomes, such as prematurity, low birth weight and preeclampsia. The explanation for this hypothesis is based on the fact that periodontal disease is an infectious state, which may increase maternal serum cytokines through the release of such agents directly from the periodontal pocket or by through the dissemination of pathogenic bacteria, inducing systemic production. This assumption is based on the knowledge that the physiopathology of the pregnancy complications cited above is associated with the presence of some cytokines in the maternal serum. The present study work has the objective to review literature in search of evidence to these alleged associations. Although a number of clinical studies have been found in this review, we noticed a lack of methodological standards, what limits the conclusions about this topic. On the other side, the fact that periodontal disease is not yet a confirmed risk factor for adverse pregnancy outcomes does not reduce the importance of oral health maintenance during pregnancy, since it is important to allow adequate feeding without pain and bleeding in order to maintain an adequate nutritional supply.
