OBJECTIVE To evaluate the potential of 980-nm gallium aluminum arsenide (GaAlAs) and 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers to reduce bacteria after irradiation of implant surfaces contaminated with Enterococcus faecalis and Porphyromonas gingivalis and on irradiated implant surface morphology. BACKGROUND Despite the frequency of(More)
Intramucosal inserts made of zirconia ceramic have been used for the rehabilitation of edentulous patients. This study aimed to follow up on patients with complete dentures having intramucosal zirconia inserts and to perform a histological analysis of biopsies of the epithelium surrounding the inserts. Twelve 31-66-year-old subjects of both genders received(More)

The aim of this study was to investigate the adhesion (4 and 24 h) and the morphology of fibroblast Balb/c 3T3 seeded onto polystyrene, partially stabilized (ZrO(2)Y(2)O(3)), stabilized zirconia ceramic (3YTZP), and pure titanium (Ti, grade 2). Initial cell adhesion (4 h) was greater (P < 0.05, analysis of variance and Tukey's Multiple Comparisons Test)(More)

Marginal apical leakage was evaluated in root canal filling performed with two sorts of cements after applying Nd:YAG laser or an EDTA solution in the root canal walls. Sixty-two human lower premolars had their canals instrumented through mechanical technique. Afterwards the external root surfaces were impermeabilized, except for the foramen. The roots were(More)
