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.

Objective: To examine the effects of revision of the package insert of varenicline implemented in July 2011 to restrict hazardous machine operations, including driving, on the success of smoking cessation treatment.
Methods: The subjects were 126 patients who visited the smoking cessation clinic at our hospital. We examined the prescription rate of varenicline and nicotine patch and the success rate of smoking cessation before (October 2010 to June 2011) and after (July 2011 to January 2013) the revision.
Results: The prescription rate of varenicline showed a significant decrease from 92.6% before the revision to 79.2% after the revision. The success rate of smoking cessation was 74.1% (varenicline: 76%, nicotine patch: 50%) before the revision and 65.3% (varenicline: 70.2%, nicotine patch: 46.7%) after the revision, showing a tendency towards decrease, but no statistically significant difference.The most frequent reason for the choice of nicotine patch after the revision was the need for driving or machine operation (53.3%).
Discussion: It is natural that the prescription rate of varenicline showed a decrease with the above revision.The success rate of smoking cessation was not decreased significantly, but there is a possibility that the restriction which was stricter than that in other countries caused a decrease in the availability of smoking cessation aids, leading to disadvantages for patients.
Conclusion: While prescribing varenicline, driving and other operations should not be prohibited across the board, but permitted with reservations, as in other countries.
