Presence of bacteria in dentinal tubules

This study demonstrated that a significant number of bacteria is present in the radicular dentinal tubules of periodontally diseased human teeth. Ten periodontally diseased teeth were prepared and stained by Brown and Brenn technique for histological examination. Bacteria were detected in all teeth. It is suggested that bacteria may invade dentinal tubules exposed to periodontal pocket and are very hard to be eliminated by conventional mechanical and chemical periodontal therapy. Contaminated dentinal tubules of periodontally diseased teeth can thus act as active bacterial reservoirs to promote recolonization of mechanically treated root surfaces, which could interfere with the periodontal healing and progression of the disease

Recobrimento de múltiplas recessões com enxerto subepitelial: tratamento de descontaminação da superfície radicular com laser de Erbium YAG

Multiple gingival recessions may cause mainly dentinary sensibility and aesthetic alterations. The subepithelial graft is a mucogingival technique which can be used to treat multiple gingival recessions. In this case report the Erbium YAG laser was applied to promote radicular surface decontamination, an important step to reach reinsertion of the gingival tissues on exposed radicular surface.Las recesiones gingivales múltiples, pueden provocar sensibilidad dentinaria y alteraciones estéticas principalmente, lo que hace que el paciente busque tratamiento periodontal. El injerto subepitelial es una técnica mucogingival que puede ser utilizada para solucionar las recesiones múltiples. En este caso clínico se utilizó laser de Erbium YAG para descontaminar la raíz, un paso importante en la técnica del injerto subepitelial para alcanzar reinserción de los tejidos gingivales en las raíces expuestas.Recessões gengivais múltiplas podem causar principalmente sensibilidade dentinaria e alterações estéticas que fazem o paciente buscar tratamento periodontal. O enxerto subepitelial é uma técnica mucogengival que pode ser aplicada para a resolução das recessões múltiplas. Neste caso clinico utilizou-se o laser de Erbium YAG para promover a descontaminação radicular um passo importante na técnica de enxerto subepitelial para alcançar reinserção dos tecidos gengivais nas raízes expostas

An alternative maneuver to treat gingival recession

This article reports a clinical case in which was applied autologous bone graft associated with subepithelial connective tis- sue graft, harvested by gingivectomy procedure with technical modifications to increase gingival graft extension, also to be used as guided tissue regeneration, to treat a single gingival recession. After 1 year and 2 months of follow-up, the cover- age of the recession was 4.0 mm, which corresponded to the gain of attached keratinized gingival tissue. An increase in the gingival tissue thickness was observed, without significant probing depth. The procedures applied to treat this case may be biologically and clinically useful to treat gingival recession

Periodontite ulcerativa necrosante: tratamento fisico da superficie radicular com Er YAG laser

Necrotizing ulcerative periodontitis is associated with bacteria and predisposing risk factors. The treatment is centered in elimination and/or control of the bacteria and predisposing risk factors. However the disease acute phase could induce sequelae as periodontal tissue destruction which may be treated by periodontal surgical procedures.La peridontitis ulcerada necrosante tiene un factor que causan la enfermedad relacionado a la acción de las bacterias y predispone a factores de riesgo. Su tratamiento se basa en la eliminación y/o control de los agentes que causan la enfermedad, pero por provocar secuelas tales como perdida de tejido peridontal, puede existir la necesidad de cirugias peridontales para intentar recuperar tejidos perdidos durante la etapa crítica de la enfermedad.A periodontite ulcerativa necrosante tem fator etiológico relacionado à ação de bactérias e fatores predisponentes de risco. Seu tratamento é baseado na eliminação e/ou controle dos agentes etiológicos, mas por provocar sequelas como perdas de tecidos periodontais, pode haver a necessidade de cirurgias periodontais que visem tentar recuperar tecidos perdidos durante a fase aguda da doença

Procedimentos básicos em periodontia: método lógico para estabilizar a doença periodontal avançada

To treat periodontal disease is essential to establish a control in all etiological factors that cause destructive activity in periodontal tissues. Basic periodontal therapy may be applied to eliminate or/and to control all etiologic factors involved in disease development. In this paper, some aspects to stabilize advanced periodontal disease using basic periodontal therapy are analyzed and discussed.Para tratar a doença periodontal, é essencial controlar todos os agentes etiológicos envolvidos que possam desencadear a doença. Os procedimentos básicos são um conjunto de métodos aplicados para eliminar e/ou estabelecer um controle em todos os fatores etiológicos envolvidos no desenvolvimento da doença periodontal. Neste trabalho, alguns detalhes para estabilizar a doença periodontal avançada através dos procedimentos básicos serão analisados e discutidos
