Objective: To evaluate the effect of antimicrobial photodynamic therapy (aPDT) using the photosensitizer hypericin-glucamine in the progression of experimentally induced periodontal disease (PD) in rats.
Material And Methods: Subgingival ligatures were inserted around the upper second molars of 30 rats. After 7 days (Baseline), the animals were randomly distributed into 3 experimental (n = 5) groups: Hypericin-glucamine; LED (amber LED, 700 mA, 590 nm, 90 mW, 34.
Effects on Bone Repair of Osteotomy With Drills or With Erbium, Chromium: Yttrium-Scandium-Gallium-Garnet Laser: Histomorphometric and Immunohistochemical Study.

Background: The erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser has been widely used in the dental clinic; however, few studies have demonstrated the advantages of the use of this laser for bone osteotomies. The purpose of this study is to evaluate and compare the bone repair process of defects generated by the Er,Cr:YSGG laser or conventional drills.
Methods: Ninety-six rats were divided into two groups of 48 animals (drill group and laser group).
