Purpose: This retrospective cohort study aims to compare the long term success of composite restorations and stainless steel crowns (SSCs) when the patient is treated under nitrous oxide (N2O), oral conscious sedation (OCS), or general anesthesia (GA).
Methods: Data was collected from the USC Pediatric Dental Clinic’s electronic patient records. Patients seen for dental treatment from 01/01/2012 to 09/01/2022 were included. A filter was applied for any tooth that has had more than one procedure code charged out. Type of sedation, tooth treated, treatment type, initial and re-treatment dates, treatment reason, patient age at time of treatment, and operator experience were recorded.
Results: Out of a total 1133 charts, 436 charts were included, for a total of 909 teeth. The average patient age difference between time of the first treatment and time of re-treatment was highest under GA (2.76 years) [OCS (2.58 years), N2O (2.22 years)]. Most common reason for re-treatment of composite restorations was the presence of new caries. Average time composite restorations lasted across all sedation modalities was around 2 years. SSCs done under GA (2.89 years) lasted longer than those done under OCS (2.30 years) and N2O (1.97 years). Most redone teeth were #A and #J, and the least re-done teeth were #I and #L. Statistical analysis pending.
Conclusion: Our results appear to show that the patient’s age does not affect the success of carious primary molar treatment, whereas the sedation modality affected the success of SSCs.
