Abstract:
To investigate risk factors for the loss of multi‐rooted teeth ( MRT ) in subjects treated for periodontitis and enrolled in supportive periodontal therapy ( SPT ). Material and Methods A total of 172 subjects were examined before (T0) and after active periodontal therapy ( APT )(T1) and following a mean of 11.5 ± 5.2 ( SD ) years of SPT (T2). The association of risk factors with loss of MRT was analysed with multilevel logistic regression. The tooth was the unit of analysis. Results Furcation involvement ( FI ) = 1 before APT was not a risk factor for tooth loss compared with FI = 0 ( p = 0.37). Between T0 and T2, MRT with FI = 2 ( OR : 2.92, 95% CI : 1.68, 5.06, p = 0.0001) and FI = 3 ( OR : 6.85, 95% CI : 3.40, 13.83, p 〈 0.0001) were at a significantly higher risk to be lost compared with those with FI = 0. During SPT , smokers lost significantly more MRT compared with non‐smokers ( OR : 2.37, 95% CI : 1.05, 5.35, p = 0.04). Non‐smoking and compliant subjects with FI = 0/1 at T1 lost significantly less MRT during SPT compared with non‐compliant smokers with FI = 2 ( OR : 10.11, 95% CI : 2.91, 35.11, p 〈 0.0001) and FI = 3 ( OR : 17.18, 95% CI : 4.98, 59.28, p 〈 0.0001) respectively. Conclusions FI = 1 was not a risk factor for tooth loss compared with FI = 0. FI = 2/3, smoking and lack of compliance with regular SPT represented risk factors for the loss of MRT in subjects treated for periodontitis.
