Experimental: Tobacco cessation intervention
Tobacco cessation intervention is implemented for 12 weeks. The nicotine dependence status is evaluated by the FTND (Fagerstrom Test for Nicotine Dependence) test. The point 3 or more is regarded as a moderate or high tobacco dependence and determining a cessation intervention. During the tobacco cessation intervention for the subjects, attending doctors implement standard treatments for their oral diseases. Even if participants fail to abstain from smoking, the oral treatment is continued. In case of the use of the NRTs (nicotine patch and/or gum), the investigators supply it for 2 weeks as a free of charge, and later the subjects themselves purchase it as over the counter (OTC) drugs at a pharmacy.
Other: Tobacco cessation intervention
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.
No Intervention: Non-tobacco cessation intervention
Those who do not intention to abstinence from smoking strongly and/or having less than 3 points in FTND test are allocated to non-tobacco cessation intervention group. The same treatment as the tobacco cessation intervention group is carried out for their oral diseases.
- Pocket depth in peridontitis [ Time Frame: Change from baseline at 12 months ]Pocket depth and attachment loss with or without surgical treatment
- Per-implant marginal bone loss [ Time Frame: Change from baseline at 12 months ]Per-implant marginal bone loss by a standardized X-ray photo
- Size reduction of oral mucosal diseases [ Time Frame: Change from baseline at 12 months ]Size reduction (major x minor axis /mm) at a predominant site for non-surgical group
- Tobacco abstinence rate [ Time Frame: 3,6,12 and 24 months ]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™.
- HPV-DNA detection (p16 & 18) [ Time Frame: pre- and post-treatment (12 months) ]The oral mucosa tissues are collected by buccal swab.
