Background: 22q11.2 deletion syndrome (22q11.2 DS) is a rare genetic syndrome characterized by high phenotypic variability, with an incidence of approximately 1:4000 live births. Most of the existing literature consists of case reports or case series, making it challenging to obtain large cohorts for data comparison and drawing generalizable conclusions. Aim: The aim of this article is to share the clinical experience of patients with 22q11.2 DS who were previously evaluated by Child Neuropsychiatry and underwent odontoiatric procedures at the Dental Unit of the Policlinico di Bari. Methods: We report three clinical cases of pediatric patients with 22q11.2 DS who were managed at the University Dental Unit of the Policlinico di Bari for dental procedures, including pre/post-treatment images and child neuropsychiatric characteristics. Results: Cleft lip and cleft palate are the most commonly encountered facial malformations. Enamel hypoplasia and hypomineralizations, caries, dental agenesis, and hypodontia are reported with variable frequency in almost all studies considering the oral health of these patients. Our experience is coherent with the data present at the moment. The clinical examinations showed diffuse hypomineralization and several caries, concordant with the literature. One patient received moderate sedation and another received general anesthesia; oral prophylaxis, fluoride application, pulp therapy, extractions of hopeless teeth and restorations of carious and hypomineralized teeth were performed. Conclusions: 22q11.2 DS is a genetic condition with a variable prognosis, but current trends show that patients often reach adulthood, primarily due to advancements in cardiology, which was previously the leading cause of mortality in these patients. From this perspective, collaboration among various medical specialties is crucial to implement holistic patient management programs and early interventions.
