Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this prospective study is to verify the efficacy of smoking cessation on non-surgical periodontal therapy in adult subjects with chronic periodontitis.

Smokers that were willing to quit received periodontal treatment and concurrent smoking cessation therapy. Periodontal maintenance was performed every 3 months. A calibrated examiner, blinded to smoking status, assessed periodontal status, gathered demographic and behavioural information with a structured questionnaire and measured air carbon monoxide concentration measurements.

Adjunctive smoking cessation

non-surgical periodontal therapy and concurrent smoking cessation therapy

Group Type EXPERIMENTAL

Smoking cessation therapy

Intervention Type BEHAVIORAL

Multidisciplinary smoking cessation therapy, performed by a team comprising physicians, nurses, a psychologist and dentists. It consisted of four 1-h counselling lectures, psychologist-assisted cognitive behavioural therapy, nicotine replacement therapy and medication (bupropion or varenicline). Smoking cessation motivation was reinforced by dentists at the maintenance sessions, by means of motivational interviewing techniques

Non-surgical periodontal therapy

Intervention Type PROCEDURE

full-mouth supra and subgingival scaling and root planing (with curettes and ultrasonic scaler); oral hygiene instruction and motivation and removal of intra-oral plaque retentive factors
