| Summary: | Objective
The aim of this study was to determine the smoking status and social nicotine dependence of the members of the Japanese Society of Periodontology (JSP).
Methods
Self-administered smoking status questionnaires including the “The Kano Test for Social Nicotine Dependence (KTSND)” questionnaire were distributed to the members who were selected through stratified proportional random sampling.
Results
A total of 631 members responded with a response rate of 42%. Of those who responded, 62% were males and 30% were in their 30s which was the largest percentage of all age groups. The respondents consisted of dentists (75%), dental hygienists (23%) and others (2%). With regard to workplace policy on smoking, a completely smoke-free workplace policy was reported by 48% of respondents, and 35% reported that smoking was allowed only outside of buildings. The possible rate of second-hand smoke at home was 31%. The sample included 376 people who had never smoked (60%), 211 ex-smokers (33%), and 44 active smokers (7%). The prevalence of smoking in dentists was 8%, which was higher than that in dental hygienists (2%, P < 0.05). By qualification, the prevalence of smoking in all certified periodontists was 8%, which was lower than that in general members (9%). The total KTSND score was 12.2 ± 5.2 in this sample. According to smoking status, the KTSND scores were 11.3 ± 5.1 in non-smokers, 12.9 ± 4.9 in ex-smokers, and 16.9 ± 4.8 in smokers. Smokers’ and ex-smokers’ KTSND scores were significantly higher than those in non-smokers (P < 0.01).
Conclusions
The present study highlights the importance of focusing attention on smoking cessation training in periodontal treatments addressed to JSP members.
