abstract = {Aim: To assess periodontal stability and the association between tooth- and patientrelated
factors and tooth loss during supportive periodontal care (SPC).
Materials and Methods: A prospective observational study was carried out on previously
treated periodontitis patients followed up for 5 years in SPC. The risk profile
(low, moderate, high) of each patient based on periodontal risk assessment (PRA)
scoring at baseline was evaluated, and tooth loss rates were analysed.
Results: Two hundred patients were included in the study, and 143 had 5-year follow-up
data available for analysis. The overall annual tooth loss per patient was 0.07 ± 0.14
teeth/patient/year. Older age, smoking, staging and grading were associated with
increased tooth loss rates. Most patients whose teeth were extracted belonged to the
PRA high-risk group. Both PRA and a tooth prognosis system used at baseline showed
high negative predictive value but low positive predictive value for tooth loss during SPC.
Conclusions: Overall, the tooth loss rate of periodontitis patients in this prospective
cohort study under SPC in private practice was low. Both tooth-based and patientbased
prognostic systems can identify high-risk cases, but their positive predictive
value should be improved.},
