Aim The purpose of this retrospective case series study was to evaluate the usefulness and performance of a comprehensive approach to assigning periodontal prognosis by assessing the risk of tooth loss due to periodontal disease ( TLPD ) and estimate the survival time ( ST ) of periodontally compromised teeth ( PCT ). Material and Methods The Long‐Term Outcome ( LTO ) index was utilized to assess the risk of TLPD , at baseline, in 100 patients following periodontal maintenance for a mean 24.7 year (±2.4). A TLPD prediction model was utilized to assign ST to PCT . The performance of the TLPD prediction based on both parameters was assessed. Results The mean TLPD rate increased as the LTO index increased (Kruskal–Wallis p < .001). The percentage of TLPD increased as the ST decreased, with significantly differences between the LTO categories <4 and ≥4 for all ST intervals (Mann–Whitney p < .001 to p .021). Only 21% of PCT were lost. This percentage was 58% for teeth assigned the shortest ST and increased to 71% and 88% for these teeth in LTO ≥4 patients. Conclusions This approach might be useful to predict TLPD in patients with an initial higher risk of TLPD while it was not useful in patients with lower risk of TLPD .
