Abstract

The purpose of this study is to evaluate the effect of alendronate (ALN), photodynamic therapy (aPDT), or their combination to scaling and root planning (SRP) for the treatment of experimental periodontitis (EP) in rats. Ninety six rats will be subject to the induction of periodontitis via the installation of a ligature around the left mandibular first molar. After 7 days, the ligature will be removed, and the animals will be distributed into the following groups: SRP: SRP plus saline solution; ALN: SRP plus ALN (10-5 M); aPDT: SRP plus methylene blue irrigation followed by LLLT; ALN/aPDT: SRP plus ALN and methylene blue irrigation followed by LLLT. Each group will be divided into three subgroups (n = 8) for euthanasia at 7, 15 or 30 days after the procedures. After the routine laboratory processing, the left molar will be embedded in paraffin and 4 ¼m thick semi-serial sections will be obtained in the mesio-distal direction. The sections will be subjected to the indirect immunoperoxidase method. Receptor activator of nuclear factor- k B (RANKL) and osteoprotegerin (OPG) will be evaluate. Data will be analyzed statistically.
