The Effect of Smoking and Chlorhexidine on Periodontal Tissues After Non- Surgical Periodontal Therapy in Patients With Periodontitis

The aim of this study is to evaluate whether the use of a chlorhexidine based oral antiseptic will improve clinical results of non-surgical periodontal therapy (NSPT) in smokers with periodontitis. A randomized controlled clinical trial will be carried out on 60 subjects with periodontitis- 30 smokers and 30 non-smokers. All subjects will be clinically examined. The following periodontal indices will be measured: Full mouth plaque score (FMPS), Full mouth bleeding score (FMBS), Pocket probing depth (PPD), Clinical attachment level (CAL), Gingival recession (GR) and Tooth mobility (TM). All subjects will have NSPT carried out. Half of the subjects in each group will use a 0.12% chlorhexidine based mouth rinse twice a day during 15 days. Clinical examination will be repeated 8 weeks after NSPT and compared.
