Retrospectively analysed tooth loss in periodontally compromised patients: long-term results 10 years after active periodontal therapy - patient-related outcomes

  • Background and Objective: Long-term tooth retention is the ultimate goal of periodontal therapy. Aim of this study was to evaluate tooth loss (TL) during 10 years of supportive periodontal therapy (SPT) in periodontal compromised patients and to identify factors influencing TL on patient level. Material and Methods: Patients were re-examined 120 ± 12 months after active periodontal therapy. TL and risk factors [smoking, initial diagnosis, SPT adherence, interleukin-1 polymorphism, cardiovascular diseases, age at baseline, bleeding on probing (BOP), change of practitioner, insurance status, number of SPT, marital and educational status] influencing TL on patient level were assessed. Results: One-hundred patients (52 female, mean age 65.6 ± 11 years) lost 121 of 2428 teeth (1.21 teeth/patient; 0.12 teeth/patient/y) during 10 years of SPT. Forty-two of these were lost for periodontal reasons (0.42 teeth/patient; 0.04 teeth/patient/y). Significantly more teeth were lost due to other reasons (P < .001). Smoking, baseline severity of periodontitis, non-adherent SPT, positive interleukin-1 polymorphism, marital and educational status, private insurance, older age at baseline and BOP, small number of SPT were identified as patient-related risk factors for TL (P < .05). Conclusion: During 120 ± 12 months of SPT, only a small number of teeth was lost in periodontally compromised patients showing the positive effect of a well-established periodontal treatment concept. The remaining risk for TL should be considered using risk-adopted SPT allocation.
