Restorative and patient factors associated with repeat general anesthesia for dental treatments in young children: A case-control study.

Background: The aim of this study was to assess factors associated with higher odds of undergoing repeat general anesthesia (GA2) for dental treatments.
Methods: The authors studied children up to age 48 months of age enrolled in Medicaid who underwent dental treatment under first general anesthesia (GA1). The authors used a case-control design to compare children who had a GA2 within 48 months of GA1 (case patients) with those who did not (control patients).
Results: In total, 60 case patients were age and sex matched to 120 control patients. Mean (SD) age at GA1 was 38 (5.2) months for case participants and 40 (4.7) months for control participants (P = .08). Higher caries involvement of maxillary incisors (P = .04), and lower caries involvment of canines (P = .003), first molars (P = .012), and second molars (P < .001) at GA1 was associated with higher odds of occurrence of GA2. There was a significant inverse association between full-coverage restoration on canines (P = .003), first molars (P = .001), and second molars (P = .002) at GA1 and occurrence of GA2. There was a significant direct association between the use of composites or sealants on second molars in GA1 and occurrence of GA2 (P = .02). The number of extractions at GA1 was not associated significantly with the occurrence of GA2.
Conclusions: The use of full-coverage restorations on primary molars and canines under general anesthesia (GA) was associated with lower odds of occurrence of GA2. Resin restorations and sealants on primary second molars were associated with higher odds of occurrence repeat GA. The findings support preferential use of full-coverage restorations for young children undergoing dental GA.
Practical Implications: Full-coverage restorations should be considered strongly for young children undergoing GA for dental treatments to reduce the risk of requiring GA2.
