This study is to verify the efficacy of tobacco cessation in patients with oral diseases; periodontitis, dental implant and oral mucosal diseases by a multicenter prospective trial. Tobacco cessation intervention is implemented for 12 weeks. During the tobacco cessation intervention for the subjects, attending doctors implement standard treatments for their oral diseases. Improvement of each disease is evaluated between smoking cessation intervention group and non-cessation intervention group.
It has been concluded that available evidence suggests that behavioral interventions for tobacco cessation conducted by oral health professionals incorporating an oral examination component in the dental office or community setting may increase tobacco abstinence rates among both cigarette smokers and smokeless tobacco users (Cochrane Database Syst Rev.6:CD005084.) However, efficacy of tobacco cessation for oral diseases by oral health professionals are not elucidated. There are few studies on tobacco cessation intervention by dentists but none in terms of reduction of oral diseases or further disease prevention. Association for the Japanese Academy of Maxillofacial Implants, Association for the Japanese Society of Oral and Maxillofacial Surgeons, Association for the Japanese Society of Oral Implantology, Japanese Society of Oral Medicine, Japanese Society of Periodontology, Japanese Academy of Clinical Periodontology, Japanese Society for Oral Health, Japanese Society of Dentistry for Medically Compromised Patient and Japanese Society of Oral Oncology conduct a study to verify the efficacy of tobacco cessation in patients with oral diseases; periodontitis, dental implant and oral mucosal diseases by a multicenter prospective trial.

The nicotine dependence status is evaluated by the Fagerstrom Test for Nicotine Dependence test; those who 3 or more score are eligible for the intervention. During the study, attending doctors implement a tobacco cessation intervention with standard treatments for above oral diseases. Even if the subjects failed to abstain from smoking, the treatment is continued. In case of the use of the nicotine replacement therapy, The investigators supply NRTs (nicotine patch or gum) for 2 weeks as a free of charge, and later the subjects themselves purchase it as over the counter (OTC) drugs at a pharmacy.

Biochemical validation tests confirming for quit smoking is applied for all subjects. Measurements of expired carbon monoxide (CO) where the test is available are analyzed at each period. Otherwise cotinine levels of the saliva samples are analyzed by a semi-quantitative analysis by NicAlert™.
