Objective: To assess the effect of low-level laser therapy (LLLT) on the incorporation of deep-frozen block allografts in a rabbit model.
Background Data: Studies have shown that LLLT has beneficial effects on tissue repair and new bone formation.
Methods: Bone tissue was harvested from two rabbits, processed by deep-freezing and grafted into the calvaria of 12 animals, which were then randomly allocated into two groups: experimental (L) and control (C).
Objective: To analyze factors associated with self-rated health in adults.
Methods: A population-based, cross-sectional study was performed with a sample of 2,051 adults aged between 20 and 59 years, in the city of Lages, Southern Brazil, in 2007. Household questionnaires were applied to obtain data on self-rated health, socioeconomic and demographic conditions, smoking habit, lifestyle and self-reported morbidities.
