A Biological Approach in Repair of Damaged Dental Pulp and Periapical Tissues using Platelet Rich Fibrin, Mineral Trioxide Aggregate and Laser Biostimulation.

This article describes about a biological approach in the repair of dental pulp and periapical tissues using biomaterials (platelet rich fibrin [PRF] and mineral trioxide aggregate [MTA]) and laser biostimulation. Case 1: Pulpotomy with PRF, MTA, and laser biostimulation. Patient follow-up was done at 1, 3, and 6 months. On 6 months follow-up, the patient was asymptomatic and tooth responded positively to pulp tests. Radiograph revealed normal periodontal ligament space and trabecular bone pattern. Case 2: Apexification procedure using PRF, MTA, and laser biostimulation in 31 and 41. Patient follow-up was done at 1, 3, and 6 months. On 6 months follow-up, radiograph revealed relative root lengthening, thickening of the canal walls in the apical one-third of root, and a healing lesion. Repair and regenerative potential of PRF, an enhanced cellular metabolism with laser biostimulation in combination with the sealing ability of MTA enhances the clinical success outcomes in pulpotomy and apexification procedures.

Avaliaçäo "in vitro" de taças de borracha para polimento dental / Evaluated \"in vitro\" of the rubber cups for dental polishing

Vários procedimentos preventivos e terapêuticos incluem o polimento dental. O mesmo é realizado nas superfícies livres, com taças de borracha. Sua forma e consistência säo importantes para que seu uso näo seja lesivo à polpa e ao periodonto. O presente estudo avaliou, a nível laboratorial, as taças de borracha existentes no mercado quanto à força necessária para ocorrer deformaçäo, quanto à deformaçäo sob força constante e quanto à geraçäo de calor com o uso. Diferenças significativas foram observadas em todos os parâmetros avaliados para os diferentes modelos de taça de borracha, sugerindo que as taças sem septos e de borracha macia poderiam "in vitro" ser menos lesivas ao periodonto e aos tecidos pulpares

Efectividad del tratamiento endodóntico de pulpas no vitales en sesión única: estudio clínico / Effectivenes of endodontic treatment of non vital pulp in unique section inclinical study

Este trabajo aporta evidencias empíricas en favor de la utilización del tramiento de conducto con pulpas no vitales en sólo una sesión y en tal sentido, se inscribe dentro de ese movimiento de constante renovación y restauración que actualmente penetra hasta las más inquebrantales concepciones de toda disciplina científica
