[Evaluation of therapeutic effect of children's dental treatment under general anesthesia: 111 cases report].

OBJECTIVE

To retrospectively evaluate the efficiency of dental treatment under general anesthesia (GA) in child patients, and analyze the related factors.

METHODS

The records of patients treated under GA in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology, between Aug 2008 and Jun 2012 were collected and analyzed. Two hundred and twenty eight records were found, of which 111 patients under 18 years old who were recalled more than 3 months after GA were selected randomly. The unplanned treatments including caries, failed restoration, root canal treatment and space maintenance fall-off etc. were recorded and analyzed. The survival rate and median survival time of the teeth were calculated, and a multivariate analysis was performed by Cox proportional hazard model.

RESULTS

Totally, there were 1 415 teeth treated under GA. The median survival time was 825 days, 77.0% of the teeth were present during their recall period. The median time of the first unplanned treatment was 215 days, and the failed restoration was the main reason for the unplanned treatment. Other factors such as the age at treatment, gender, total number of decayed teeth, reason for GA, and living place were found unassociated with the survival rate.

CONCLUSION

The effect of dental treatment under GA is satisfied. Regular dental visit after GA is very important for children's dental health.
