A retrospective cohort study of pediatric hospitalization due to dentoalveolar infection before and after a change in national health insurance

This retrospective cohort study aimed to examine trends in pediatric (0–18 years old) hospitalizations due to dentoalveolar infection, before and after the inclusion of pediatric dental care in Israel’s National Health Insurance Law.
