Smoking cessation and response to periodontal treatment

Aust Dent J. 2018 Jun;63(2):140-149. doi: 10.1111/adj.12568. Epub 2017 Oct 24.


Smoking has detrimental oral effects. The aim of this study was to review the literature related to the impact of smoking cessation on periodontal health, periodontal disease and periodontal treatment outcome as well as to review the smoking cessation strategies and the dentist's role in the smoking cessation effort. Smoking cessation seems to have a positive effect on the periodontium, to decrease the risk for incidence and progression of periodontitis and to lead to a non-significant trend for greater mean probing depth reductions after non-surgical treatment over a 12-month period. Smoking cessation effect on the periodontium should be further investigated. Dentists should inform their patients on the harmful effect of smoking and the beneficial effect of smoking cessation on oral health. They should advise, motivate and support their patients to quit smoking. Smoking-control strategies should be incorporated in dental practise. The dentist's role in the smoking cessation effort is important. Guidelines on smoking-control strategies applied in the dental office are required.

Keywords: periodontal treatment; periodontitis; smoking; smoking cessation; smoking cessation strategies.
