Correlation of periodontal inflamed surface area with the effect of vitamin d supplement and low level laser therapy as an adjunct to scaling and root planing in periodontitis patients with type 2 diabetes mellitus and vitamin d insufficiency - a randomized controlled clinical trial

Aim of the study is to evaluate and corelate periodontal inflamed surface area with the effect of Vitamin D supplement and low level laser therapy on HbA1c, serum Vitamin D levels and clinical parameters when used as an adjunct to scaling and root planing in non surgical management of Vitamin D insufficient stage 2 grade B or grade C periodontitis patients with type2 diabetes mellitus.

The study population will consist of individuals of both genders, in the age group of 30 to 65 years who volunteer to participate in the study and also fulfill the inclusion and exclusion criteria, all the subjects will recruited after providing the participants with an information sheet, explaining the purpose, nature and design of the study and obtaining a written informed consent from the subjects choose for the study.

group 3 consist of 15 subjects will be subjected to scaling, sham and Vitamin D supplement once a week for 10 weeks, group 4 consis of 15 subjected to scaling and root planing and will be subjected to sham and placebo. Then assessing clinical parameters, serum vitamin D level  and Hb1Ac at basline and 3 months after scaling and root planing in all 4 groups.
