Impact of Oral Health and Sociodemographic Factors on Quality of Life: A Cross-sectional Study.

The aim of this study was to determine the impact of oral health and socioeconomic variables on the quality of life in a sample of low-income Brazilians. The sample consisted of 400 adults assisted by the Rescuing Smiles Social Program (Pernambuco University) in June 2014 in the town of Arcoverde, Pernambuco. Two 18+ physically and mentally healthy people were chosen to participate in the study per household.

Antinociceptive effects of low-level laser therapy at 3 and 8 j/cm in a rat model of postoperative pain: possible role of endogenous Opioids.

Low-level laser therapy (LLLT) is the direct application of light to stimulate cell responses (photobiomodulation) to promote tissue healing, reduce inflammation, and induce analgesia; the molecular basis for these effects of LLLT remains unclear. The objective of this study was to evaluate the analgesic effect of LLLT in the rat plantar incision model of postoperative pain as well as to investigate some of the possible mechanisms involved in this effect. Wistar rats were submitted to plantar incision and treated with LLLT (830 nm, continuous-mode, 30 mW/cm , 1-12 J/cm ).
