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. Data were collected from the medical records of one oral and maxillofacial surgery department. Data were compared between patients hospitalized during 2002–2010 (group A, n = 531) and 2011–2019 (group B, n = 381). The mean age of the cohort was 8 years. A dentoalveolar abscess was the main cause of hospitalizations in both groups. Group B exhibited a higher rate of previous dental treatment in general (p = 0.001), and of previous dental treatment for the tooth responsible for the infection (p = 0.03). The prevalent treatment during hospitalization combined intravenous antibiotics and extraction, with or without drainage (58.1%) for group A; and intravenous antibiotics and drainage (49.4%) for group B (p < 0.01). Dental care provided by the Israel’s National Health Insurance should focus not only on operative treatment but also on oral health promotion and caries prevention, to reduce hospitalizations due to dentoalveolar infections.
