Predictors of smoking cessation in smokers with chronic periodontitis: a 24-month study

Abstract

The purpose of this 24-month study was to identify predictors of smoking cessation in a cohort of smokers with chronic periodontitis, attending a multidisciplinary smoking cessation program. Of the 286 subjects screened, 116 were included and received non-surgical periodontal treatment and smoking cessation therapy, which consisted of lectures, cognitive behavioral therapy, and pharmacotherapy, according to their individual needs. During initial periodontal treatment, dentists actively motivated the study subjects to stop smoking, using motivational interviewing techniques. Further smoking cessation counseling and support were also provided by the dentists, during periodontal maintenance sessions at 3, 6, 12 and 24 months of follow-up. Smoking status was assessed by means of a structured questionnaire, and was validated by exhaled carbon monoxide (CO) measurements. The Fagerström Test for Cigarette Dependence was used to assess smoking dependence. Of the 61 individuals that remained up to the 24-month examination, 31, 21 and 18 declared that they were not smoking at 3, 12 and 24 months, respectively. Smoking cessation after 24 months was associated with the male gender (OR = 3.77, 95%CI = 1.16-12.30), baseline CO levels less than 10ppm (OR = 5.81, 95%CI 1.76-19.23), not living or working with another smoker (OR = 7.38, 95%CI 1.76-30.98) and a lower mean Fagerström test score (OR = 5.63, 95%CI 1.55-20.43). We concluded that smoking cessation was associated with demographic, smoking history and cigarette dependence variables.

Impact of Smoking Cessation on Periodontal Tissues

“…The results demonstrated that the success of smoking cessation was associated with male gender, baseline carbon monoxide levels less than 10 ppm, not living or working with smokers, and the baseline cigarette dependence level. 19 …”

Preditores da cessação de tabagismo em fumantes reabilitados com implantes dentários

“…A associação de cessação de tabagismo com sexo também foi encontrada em um estudo anterior do nosso grupo em fumantes com periodontite severa (Inoue et al, 2016), no qual 50% dos participantes que pararam de fumar eram homens, comparados a 20,9% dos que não conseguiram parar de fumar. Por outro lado, esses resultados divergem de um estudo anterior do nosso grupo (no estudo de Inoue et al, 2016), além de sexo masculino, níveis de monóxido de carbono expirado menores que 10 ppm, não viver ou trabalhar com outro fumante e baixa pontuação do teste de Fagerström também foram preditores de cessação de tabagismo em fumantes com periodontite severa.…”

“…Um estudo prospectivo de nosso grupo mostrou que mulheres, pessoas que vivem ou trabalham com fumantes e com maior dependência ao cigarro no início do estudo, apresentam menor chance de conseguir parar de fumar (Inoue et al, 2016).…”
