Research Abstract	In patients with periodontitis, a quantitative prognostic assessment is needed for successful supportive periodontal treatment (SPT). We have conducted two-year follow up study at our dental hospital. Study subjects were 62 patients receiving SPT and they were asked to participate in the study twice. Life-style and oral health behavior were asked via self-administered questionnaire and changes in periodontal status were evaluated by the dentist. Of these, current smokers were excluded from the analyses. Using a multivariate approach, baseline findings of medication and smoking history were independent prognostic factors for keeping periodontal tissues healthy. These findings may be of value for successful periodontal treatment.
