Antimicrobial photodynamic effect to treat residual pockets in periodontal patients: a randomized controlled clinical trial.

AIM: A randomized controlled clinical trial was designed to evaluate the efficacy of the photodynamic therapy (PDT) in the treatment of residual pockets of chronic periodontitis patients. MATERIAL AND METHODS: Thirty-four patients with at least four residual periodontal pockets undergoing maintenance care were included and randomly assigned to test group (PDT, n = 18) or control group (sham procedure, n = 16). The intervention was performed at baseline, 3, 6 and 12 months. Clinical parameters such as pocket probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BoP) and plaque index (PI) were measured before intervention and after 3, 6 and 12 months. Subgingival samples were obtained at baseline, and after 7 days, 3, 6 and 12 months to quantify Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia by real-time polimerase chain reaction (PCR). RESULTS: All clinical variables showed significant improvement during the study, but there was no significant difference between test and control groups. The microbiological analyses showed no differences between groups at any time during the study. CONCLUSION: Within the limits of this clinical trial and considering the laser and photosensitizer protocol used, PDT failed to demonstrate additional clinical and bacteriological benefits in residual pockets treatment.

Aumento e reconstruçäo estética de rebordo alveolar parcialmente edêntulo através de enxerto de tecido mole / Augmentation and esthetic reconstruction of partially edentulous alveolar ridge by means of soft tissue graft

Nos últimos tempos a Odontologia e seus pacientes vêm se preocupando cada vez mais com a estética. As reconstruçöes protéticas näo visam mais apenas funcionalidade. Hoje pode-se realizar procedimentos funcionais, mas também estéticos. As cirurgias para aumento de rebordo alveolar com tecido mole têm esse objetivo: proporcionar reabilitaçöes mais estéticas, melhorando também a funçäo. Assim, através de uma revisäo de literatura, seräo analisadas as indicaçöes e contra-indicaçöes de enxertos de tecido mole para aumento e reconstruçäo de defeitos de rebordo alveolar localizados e mostrados os motivos que podem levar a um defeito de rebordo, assim como algumas formas de preveni-los. Também seräo mostradas técnicas cirúrgicas através de enxerto de tecido mole para a reconstruçäo desses defeitos. Tem-se como conclusäo que existem várias técnicas de enxerto e de execuçäo da técnica, e que, quando näo existe a necessidade de colocaçäo de implantes osseointegrados, as técnicas com tecido mole säo superiores àquelas que necessitam de enxerto näo autógeno

Emprego endodôntico da clorexidina: perspectivas atuais e futuras / Use of chlorhexidine in endodontics: current and future perspectives

A clorexidina é um agente antimicrobiano que tem sido utilizado em Odontologia. Recentemente seu uso tem sido introduzido também na prática endodôntica. O objetivo deste estudo é revisar as várias indicaçöes para uso da clorexidina em Odontologia, particularmente em Endodontia. Perspectivas futuras para o emprego desta substância também säo discutidas
