179 - Success of Dental Restorations Performed under Various Behavior Guidance Techniques

Purpose: To compare the success rates of dental restorations completed under nitrous oxide inhalation and general anesthesia for pediatric patients with early childhood caries.

Methods: A retrospective chart review of pediatric patients who received treatment at BronxCare Health System Pediatric Dental Clinic under nitrous oxide inhalation or general anesthesia during a four-year period from January 2014 through December 2018 was completed. Only 307 of 1,724 charts were eligible as these subjects returned for their periodic oral examination within a 12 to 24 month period to evaluate placed restorations. For the two groups, the following was noted from the Dentrix Electronic Dental Health Record: gender, age, date of treatment, number of class 2 composites, number of pulpotomies, number of stainless steel crowns, date of recall examination, number of successful class 2 composites, number of successful pulpotomies, and number of successful stainless steel crowns.

Results: The sucess rate of class 2 composites was 81.6% under nitrous oxide, 87% under general anesthesia, and 83.5% overall. The success rate of pulpotomies was 63.2% under nitrous oxide, 58.4% under general anesthesia, and 59.4% overall. The success rate of stainless steel crowns was 77.9% under nitrous oxide, 69.4% under general anesthesia, and 73.4% overall.

Conclusions: Class II composite restoration was the most
successful restoration regardless of treatment
modality. Success rate of pulpotomy was the lowest
regardless of treatment modality.
