AimTo evaluate the periodontal status of single-rooted endodontically treated teeth (ET), correcting for patient- and tooth-related factors.
MethodsClinical parameters (BoP,PD,CAL) of 240 ET and 240 contralateral vital teeth (VT), before and after non-surgical periodontal treatment, were extracted retrospectively from the journals of 175 patients. Possible patient-related (age, gender, smoking status) and tooth-related (interproximal restoration, root canal filling's extent, post, tooth type) confounders were tested.
ResultsAt baseline, frequency of BoP at an interproximal site at ET versus VT was 70.4% versus 65.0%, respectively. The frequency of teeth with interproximal PD 5mm and CAL 5mm was 47.9% versus 42.9% and 54.6% versus 49.6% at ET and VT, respectively. Interproximal PD and CAL at ET versus VT were 3.86 versus 3.61mm and 4.11 versus 3.95mm. After correcting for tooth-related factors, no significant differences were observed between ET and VT. An improper restoration had a significant (p<0.001) negative effect on BoP [OR 3.49 (95%CI: 1.95-6.27)], PD [36.81% (95%CI: 18.52-57.92)] and CAL [27.01% (95%CI: 12.67-43.18)]. No significant differences between ET and VT were observed regarding clinical outcome of non-surgical periodontal therapy.
ConclusionsPresence of a root canal filling per se does not have a significant negative influence on the marginal periodontium, when correcting for the quality of the interproximal restoration.
