Brief summary
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.
Interventions
BEHAVIORALSmoking cessation therapy
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
PROCEDURENon-surgical periodontal therapy
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
