Peri-implant osseointegration after low-level laser therapy: micro-computed tomography and resonance frequency analysis in an animal model.

The purpose of the present study is to evaluate the effects of low-level laser therapy on the osseointegration process by comparing resonance frequency analysis measurements performed at implant placement and after 30 days and micro-computed tomography images in irradiated vs nonirradiated rabbits. Fourteen male New Zealand rabbits were randomly divided into two groups of seven animals each, one control group (nonirradiated animals) and one experimental group that received low-level laser therapy (Thera Lase®, aluminum-gallium-arsenide laser diode, 10 J per spot, two spots per session, seven sessions, 830 nm, 50 mW, CW, Ø 0.0028 cm).

Assessment of marginal adaptation after apicoectomy and apical sealing with Nd:YAG laser.

Objective: Recurrent periapical disease poses a substantial challenge to the dental practitioner. However, the use of novel methods and materials in periapical surgery has increased the success rates of treatment. The objective of this study was to assess the effects of mineral trioxide aggregate (MTA) retrofilling and apical sealing with Nd:YAG laser (at 10 Hz, 150 mJ, 1.

Objectives: 1) To investigate the association between binge eating scores, anxiety and depression symptoms, and body mass index (BMI), and 2) to assess the presence of differences in severity of anxiety symptoms, severity of depression symptoms, and BMI in women with and without binge eating disorder.

Method: The sample comprised 113 women aged between 22 and 60 years (39.35±10.

Histological and physical analysis of bone neoformation by osteogenesis distraction: A preliminary report.

Introduction: Osteogenesis distraction (OD) is a mainstream technique in maxillofacial surgical reconstruction with varied applications. OD technique employs a distractor with the aim to get new bone in the site of interest. Osseous maturation time is necessary before the device can be removed and few patients' complaint of related discomfort, especially when these devices are external, and induces superficial infections, paresthesia, hypertrophic scars and social relationship difficulties.

[Translation, adaptation, and validation of the Brazilian version of the Marijuana Expectancy Questionnaire].

This study presents the translation and validation of the Marijuana Expectancy Questionnaire (MEQ-Brazilian Adaptation), which evaluates the expectancy of results in marijuana use, important for treatment and prognosis related to addiction to this substance. The sample consisted of 400 subjects, 217 males and 183 females, of whom 147 were marijuana users and 253 were non-users. In the user group, 90 subjects were marijuana-dependent.

Factors associated with the successful aging of the socially-active elderly in the metropolitan region of Porto Alegre.

Objective: To identify the factors associated with aging of the socially-active elderly in the metropolitan region of Porto Alegre.

Methods: A cross-sectional study was conducted involving a sample of 400 elderly subjects. Through a conglomerate analysis using the combined results of the Flanagan Scale and the quality of life assessment instrument developed by the World Health Organization (WHOQOL-100), the subjects classified as presenting a higher quality of life were considered to have aged successfully.
