Abstract
- Aim To understand degeneration of healthy sites and identify factors associated with disease progression in patients with chronic periodontitis. Material and Methods Data on healthy sites from 163 American and Swedish subjects were analysed using two-three-state (health, gingivitis, chronic periodontitis) Markov models based on bleeding on probing ( BOP), and either clinical attachment level ( CAL) + BOP or pocket depth ( PD) + BOP. Results In 2 years, 10% ( CAL + BOP) and 3% ( PD + BOP) of healthy sites developed chronic periodontitis. On average, healthy sites remained healthy for 32 months before transiting in both models. Most transitions (87-97%) from health were to the gingivitis state. The expected duration of the gingivitis lesion was 4-5 months and sites recovered with a high probability (96-98%). Disease severity as measured by number of sites with CAL/ PD > 4 mm at baseline and smoking, were associated with fast progression from health to chronic periodontitis within 6 months as were gingival redness in the PD + BOP model only. With age, the rate of disease progression to gingivitis decreased. Conclusion Transition probabilities for gingivitis and chronic periodontitis were higher with CAL + BOP than with PD + BOP. Smoking and disease severity were significant predictors for fast progression. [ABSTRACT FROM AUTHOR]
