Abstract:

Objectives: Tooth pain, as measured in the clinic, can have broad impact on patients’ lives. The objective is to assess the association between patient-reported tooth pain and health-related quality of life (HRQoL) one week following initial orthograde root canal treatment (RCT).

Methods: This study uses data from the Predicting Outcomes from Root Canal Treatment (PREDICT) study, baseline conducted April-September 2017, by the National Dental Practice-Based Research Network (www.NationalDentalPBRN.org). We use Spearman’s rank correlation to measure the association between patient-reported current pain level and HRQoL, using health utilities derived from the EuroQual 5-dimension, 5-level (EQ5D5L) health classification system. The EQ5D5L combines patient responses for five health dimensions (mobility, self-care, usual activities, pain, anxiety) into a health utility score between 1.0 (perfect health) and 0.0 (dead). Patients completed 1-week post-obturation questionnaires to capture worst pain intensity, on a 0 (no pain) to 10 (worst pain imaginable) scale. We also assess the association between pain and a) individual components of the EQ5D5L, and b) self-reported overall health rated on a 5-level scale (poor-excellent). We report preliminary data collected through August 31, 2017.

Results: Dentists enrolled 998 patients receiving a RCT through August, with 743 completing 1-week post-RCT assessments. Mean current pain was 0.69 (0.58, 0.80), mean HRQoL was 0.92 (0.91,0.93), and mean overall health was 2.66 (2.60, 2.72). Current pain was negatively correlated with health utility score (Spearman correlation coefficient (SCC) =-0.51; p<0.0001). There was a positive correlation with 1-week pain and the dimension of the EQ5D5L (SCC = 0.61; p<0.0001). One-week pain was negatively correlated with self-reported overall health (SCC=-0.15; P<0.0001).

Conclusions: Patient reported mean current tooth pain 1-week post-RCT was low, and mean HRQoL was high. Higher levels of tooth pain were moderate associated with lower HRQoL. Pain at 1-week was only weakly correlated to overall measures of health. Support: U19-DE-22516.
