Effect of periodontal disease on electromyographic activity of muscles of mastication: A cross-sectional study.

Aim: This study aims to compare surface electromyographic activities (EMG) of four muscles, that is anterior temporalis (AT), masseter (MST), sternocleidomastoid (SCM) and anterior belly of digastric (ABD), between chronic periodontitis patients and periodontally healthy individuals as well as to correlate these EMG findings with periodontal parameters.

Methods: Thirty chronic periodontitis patients were recruited in Group I and 30 periodontally healthy individuals in Group II. Clenching and resting EMG for 4 muscles (AT, MST, SCM and ABD) were recorded for each participant.

Effect of low-level laser therapy on wound healing after depigmentation procedure: A clinical study.

Aim: The aim of the present study is to evaluate and compare the effects of low-level laser therapy (LLLT) on wound healing after depigmentation procedure.

Materials And Methods: In this study, 12 patients with bilateral melanin hyperpigmentation were treated with surgical stripping using a blade. After completion of the surgical process and bleeding stasis, any of the symmetrical surgical sites was randomly assigned for LLLT (test site) using a defocused diode laser at 1 mm distance for 5 min.
