Objective: The purpose of this study was to perform a comprehensive audit of dental treatment provided to special needs patients (SNP) under general anesthesia (GA) over a ten-year period. Study design: Special needs patients who received dental treatment under GA as an in-patient at Queen Mary Hospital, Hong Kong SAR during the time period January 2002 and December 2011 were included in the study. The study population was divided into three groups, based on age (<6years, 6–12 years, >12 years). One-way ANOVA was used to evaluate the effect of “age group” on duration of treatment, post-recovery time, treatment procedures and utilization of different restorative materials. Kappa statistics were used for intra-examiner reliability. Results: A total of 275 patients (174 males and 101 females) were included in the study. The mean age of the patients at the time they received GA was 12.37±10.18 years. Dental procedures performed were mostly restorative in nature (47%). The >12 years group had significantly shorter treatment duration (p<0.05). No significant difference in post-operative recovery time was observed among the three age groups (p>0.05). The <6 years group received significantly less preventive, but more restorative procedures (p<0.05). Significantly fewer extractions were performed in the 6–12 years group (p<0.05). The use of composite restorations was significantly higher in the <6 years group; while amalgam restorations were more frequently used in the >12 years group (P<0.05). Stainless steel crowns were more frequently employed in SNP under 12 years of age (p<0.05). Intra-examiner reliability was good (k=0.94). Conclusions: Most of the dental procedures performed under GA on SNP were restorative procedures. For children less than 6 years of age, had longer treatment time under GA. Composite restorations and stainless steel crowns were more frequently used in the primary dentition and amalgam restorations were more frequently employed in the permanent dentition.
