Analysis of public, private payer types for root canal therapy on children and adolescents in Massachusetts

---

Background

Despite substantial increases in dental benefits and improvements in the use of dental services among children and adolescents in the U.S., oral health disparities according to dental insurance payer type persist.

Methods

The authors used an all-payer claims database for 2013 to 2017 to perform a comparative analysis of the provision and treatment outcomes of root canal therapy in the permanent teeth of a pediatric population aged 6 through 18 years. Researchers conducted the analysis according to dental insurance payer type. The team performed statistical analyses, including logistic regression, Cox proportional hazards regression and the Kaplan-Meier method at person and tooth levels.

Results

Compared with privately insured children and adolescents, public-payer children and adolescent beneficiaries were more likely to have had root canal therapy and had poorer treatment outcomes associated with the procedure during the study period. Those enrolled in private insurance were more likely to receive treatment from an endodontist. Amounts allowed and paid by the insurer were significantly higher for private payers.

Conclusions

There were significant differences in the provision and outcomes of endodontic treatment between privately and publicly insured children and adolescents.

Practical implications

Despite ostensibly equal access to care, differences in the provision of oral health care exist between privately and publicly insured patients. These differences may be contributing to persisting oral health disparities.
