The results of a study to be presented at EuroPerio9 in Amsterdam found that smoking impacts periodontal healing after nonsurgical treatment.
Dr. Aorra Naji, a periodontist, from the Centre for Oral Rehabilitation, Department of Periodontology in Falun, Sweden, said. “Nonsurgical periodontal treatment significantly reduced pockets greater than 4 millimetres deep in both smokers and nonsmokers. Nevertheless, we found that the reduction was more pronounced in non-smokers, one year after treatment.”
He said the study’s objective was to investigate the impact of smoking on periodontal healing one year after nonsurgical periodontal treatment.
Data was obtained on 1,551 individuals treated between 1980 and 2015 in a specialized clinic for periodontology in Sweden. The researchers established that one-year after active treatment there was a significant reduction of the clinical parameters among both smokers and nonsmokers. While in non-smokers the pocket depth reduction was 72%, in smokers the reduction was 51%, showing that smoking impairs periodontal healing after nonsurgical periodontal treatment. Researchers also found that the proportional reduction of plaque was 69% in nonsmokers and 53% in smokers, one year after treatment.
Dr. Naji said, “Even though this study has some limitations—retrospective design, we could not analyze the impact of cigarette consumption or how former smoking influences periodontal healing—we found evidence that periodontal nonsurgical treatment leads to more pronounced pocket depth reduction in non-smokers. Larger studies are needed to investigate the influence of smoking cessation on periodontal healing.
Dr Naji advised that it is “important for members of the dental profession to work with smoking prevention, for example, by information and motivational interviewing.”
EuroPerio9 will take place from June 20-23 at the RAI in Amsterdam.
