Abstract
Objectives:The purpose of the current survey was to investigate the attitude of patients towards smoking and their knowledge of smoking as a risk factor for periodontal disease and dental implants.
Methods:The subjects were new 1,585 patients who visited the clinic of the Tokyo Medical and Dental University Hospital from January to December 2012 for an oral implant. The methodology included a questionnaire survey about smoking status for the recognition of smoking as a risk factor for periodontal disease and dental implants and the Kano Test for Social Nicotine Dependence（KTSND）.
Results:The response number was 1,159 respondents（response rate, 73%）. Smoking was recognized as a risk factor for periodontal disease by 621 patients（59%）and as a risk factor for dental implants by 234 patients 23%）. The KTSND scores of the patients with knowledge of smoking as a risk factor for periodontal disease（621 patients, 59%）and for dental implants（234 patients, 23%）were significantly lower than those of the patients without knowledge of smoking as a risk factor for periodontal disease and for dental implants, respectively.
Discussion:The recognition of smoking as a risk factor for periodontal disease and dental implants had an influence on the smoking status and attitude.
Conclusion:In order to increase the recognition of smoking as a risk factor for periodontal disease and dental implants, the informed consent process and patient education must be improved.
