1. Analysis of radiopacity, pH and cytotoxicity of a new bioceramic material
AbstractObjective RetroMTA® is a new hydraulic bioceramic indicated for pulp capping, perforations or root resorption repair, apexification and apical surgery. The aim of this study was to compare the radiopacity, pH variation and cytotoxicity of this material to ProRoot® MTA.Material and Methods Mixed cements were exposed to a digital x-ray along with an

2. Bioactivity, biocompatibility and antimicrobial properties of a chitosan-mineral composite for periodontal tissue regeneration
Abstract A composite membrane of the polymer, chitosan, and the silver-exchanged mineral phase, tobermorite, was prepared by solvent casting and characterised by scanning electron microscopy and Fourier transform infrared spectroscopy. The

3. Effect of time of extraction on the biocompatibility of endodontic sealers with primary human fibroblasts
The aim of this work was to evaluate the effects of different times of extraction on the cytotoxicity of six representatives of different root canal sealer groups-Real Seal SE, AH Plus, GuttaFlow, Sealapex, Roth 801, and ThermaSeal Plus-with human gingival fibroblasts. The materials were prepared according to manufacturers' specifications, and were incubated

4. Comparison among four commonly used demineralizing agents for root conditioning: a scanning electron microscopy
Dental roots that have been exposed to the oral cavity and periodontal pocket environment present superficial changes, which can prevent connective tissue reattachment. Demineralizing agents have been used as an adjunct to the periodontal treatment aiming at restoring the biocompatibility of roots. OBJECTIVE: This study compared four commonly used deminerali

5. Guided tissue regeneration: in vitro biocompatibility of the membrane of poly(vinylidene-trifluoroethylene)/barium titanate composite / Regeneração tecidual guiada: estudo da biocompatibilidade in vitro da membrana do compósito de poli(vinilideno-trifluoretileno)/titanato de bário
O princípio da regeneração tecidual guiada (RTG) baseia-se na utilização de membranas biocompatíveis com a finalidade de impedir a migração dos tecidos conjuntivo e epitelial para a ferida, permitindo que células do ligamento periodontal repovoem a superfície radicular e regenerem o aparato de inserção do dente. A RTG tem sido utilizada em divers

6. Tratamento regenerativo periodontal de defeitos infra-ósseos de duas ou três paredes realizados em animais e humanos, utilizando a membrana reabsorvível de osso cortical bovino (GEN-DERM), osso inorgânico bovino (GEN-OX) e ácido cítrico com / Periodontal regenerative treatment of two or three walls-defects intra bony made in animals and humans, using anorganic bovine bone, resorbable membrane of bovine cortical bone and citric acid with tetracycline
This study aimed at evaluating the biocompatibility in rabbits and the periodontal regeneration of intra-bony defects in humans, utilizing a bovine inorganic bone (Gen-Ox). Five groups of rabbits, containing 5 in each group, were sacrificed in the periods of 30, 60, 90, 180 and 270 days, following the bone graft. In the study in humans, the sample was compri

7. Matriz óssea bovina mineralizada na reparação alveolar da mandíbula de cães e sua associação com membrana de colágeno. Estudo experimental / Mineralized bovine bone matrix in the alveolar repairing of the jaw of dogs and its association with collagen membrane. Experimental study
The periodontal therapies have as objectives not only to stop the progression of the disease, by the interruption of the inflammatory action of the bacterial plate, but also to make possible the restoration of the lost structures, especially as for the maintenance of the architecture and the functional state of those. Thus, the obtained treatments as regener

8. "Moldagem em prótese parcial fixa com afastamento gengival: estudo histológico comparativo em cães entre a técnica de anel de cobre e godiva e cordão de algodão associado a cloreto de alumínio" / FIXED PARTIAL DENTURE IMPRESSION WITH GINGIVAL DISPLACEMENT: COMPARATIVE HISTOLOGICAL STUDY IN DOGS USING COPPER BAND TECHNIQUE AND STRING IMPREGNATED WITH ALUMINIUM CHLORIDE
This study carried out three dogs to gingival displacement comparing the copper band and compound gingival displacement and impression technique with string impregnated in aluminium chloride with gingival displacement technique, and single impression by condensing silicone impression material. The objective was to compare the periodontal biocompability betwe
