Analgesic effects of preinjection low-level laser/light therapy (LLLT) before third molar surgery: a double-blind randomized controlled trial.

Objective: The aim of this study was to evaluate the analgesic effects of low-level laser therapy (LLLT) on preinjection sites in patients scheduled for third molar removal.

Study Design: This double-blind randomized controlled trial included 163 healthy patients undergoing third molar extractions. The study participants were randomly divided into an LLLT and a placebo group.

A randomized prospective controlled trial of antibiotic prophylaxis in intraoral bone grafting procedures: single-dose clindamycin versus 24-hour clindamycin prophylaxis.

Purpose: The objective of this study was to compare the efficacy of a single oral dose of clindamycin with a 24-h protocol of clindamycin administration in local buccal onlay grafting procedures.

Material And Methods: A prospective randomized study in 124 patients was performed. Eligible patients were randomized to receive antibiotic prophylaxis either as a single dose (group I) or over a 24-h period (group II).
