Influence of Preventive Tooth Extractions on Quality of Life in Patients with Antiresorptive Intake-A Prospective Longitudinal Study.

Background: To find out whether preventive tooth extractions in patients on antiresorptive therapy have a direct impact on the patients' overall quality of life (QoL); Methods: QoL using the five-level version of the EuroQol Group's EQ-5D instrument (EQ-5D-5L) was longitudinally assessed in N = 114 prospectively enrolled patients with indication of preventive tooth extraction over a period of 12 months. Patients were stratified as high-risk (malignant disease with bone metastasis or multiple myeloma, with monthly high-dose antiresorptive therapy delivered intravenously [bisphosphonate] or subcutaneously [denosumab]) and low-risk/osteoporosis patients (weekly low-dose antiresorptive therapy administered orally [bisphosphonate] or half-yearly subcutaneously [denosumab]). The measurement time points were 4 weeks preoperatively (T0), 2 months (T1) and 1 year postoperatively (T2), respectively.

Results: EQ-5D-5L index scores fell in a range from -0.21 to 1.00 in the low-risk group to 0.15 to 1.00 in the high-risk group. The -test comparing the baseline index scores of both groups showed EQ-5D-5L index score in the low-risk group (0.708 ± 0.292) to be significantly smaller ( = 0.037) than in the high-risk group (0.807 ± 0.19). ANCOVA showed no significant differences in EQ-5D-5L index scores between the groups at T1 and T2.

Conclusions: Preventive tooth extractions in patients undergoing antiresorptive treatment have no negative effect on QoL. Therefore, if indicated, preventive tooth extraction should not be omitted. Patient-oriented outcome measures are important to obtain a good risk-benefit balance for patient-specific treatment.
