Abstract
The primary objective of this study was to investigate the association between pain catastrophizing, pain resilience, and treatment expectations with oral health-related quality of life (QoL) and pain outcomes (i.e., pain intensity, pain interference) in patients receiving endodontic therapy. A secondary aim was to determine whether changes in pre-/post-operative pain catastrophizing and resilience predict changes in treatment-related outcomes (i.e., oral health-related QoL, pain intensity, pain interference).
Materials and Method: This single arm quasi-experimental study included 63 adults (18+ years) diagnosed with symptomatic irreversible pulpitis who were receiving non-surgical root canal treatment. Participants completed psychological questionnaires including the Pain Catastrophizing Scale, Pain Resilience Scale, a measure of treatment expectancy, the PROMIS Pain Intensity and Interference scales, and the Oral Health Impact Profile. Questionnaires were administered pre-operatively and post-operatively two weeks after their root canal was completed. A multivariable linear regression model with demographic characteristics as potential confounders was used for statistical analysis.
Results: There were no significant associations between sociodemographic factors and outcome variables and no significant pre- to post-operative changes in either the psychological variables or the study outcomes. Multiple linear regression analyses indicated that pre-operative pain catastrophizing significantly predicted post-operative pain intensity, pain interference, and oral health QoL (all p’s >0.001). In contrast, pain resilience and treatment expectancy were not significant predictors. Additionally, changes in pain catastrophizing and pain resilience from pre- to post-operative assessment were not significantly associated with corresponding changes in pain intensity, pain interference, and oral health QoL.
Conclusion: The findings suggest that pain catastrophizing may serve as an important psychological factor to consider in the management of endodontic pain. Therefore, future research should explore targeted interventions to address pain catastrophizing in order to improve treatment-related outcomes and enhance patient experiences during endodontic therapy.
