Oral Health-related Quality Of Life In Children(3-6 Yrs.)with Dental Anxiety Before And After Treatment Under General Anesthesia

Aim: The aim of this study is to evaluate the impact of Severe Early Childhood Caries(S-ECC)on Oral Health-Related Quality of Life(OHRQo L)among 3-6year-old children with dental anxiety and compare OHRQo L of the S-ECC children before and after dental treatment under general anesthesia.Method: Ninety three S-ECC children aged 3 to 6 years with dental fear were randomly selected from June 2016 to October 2017,in Department of pediatric dentistry,Hospital of Stomatology,Guangxi Medical University.And these children received dental treatment under general anesthesia(GA).A Chinese version of the Early Childhood Oral Health Impact Scale(ECOHIS)was used to evaluate S-ECC children's OHRQo L before and after treatment.Meanwhile,110 healthy children aged 3 to 6 years without caries visiting for regular dental checkup in the clinic were randomly selected as the control group(caries free group,CF group).A questionnaire was also used to collect the information of socio-demographics,ECOHIS scales,and S-ECC parents' satisfaction with dental treatment under GA.Spearmen's rank correlation coefficient was used to evaluate the association between the severity of caries with the ECOHIS score in S-ECC group;ECOHIS scores before and after treatment in S-ECC group were compared,and also the ECOHIS scores before and after treatment in SECC group were also compared with that of CF group.Result: The ECOHIS score of S-ECC group was positively correlated to the values of decayed-missing-filled tooth surface(dmfs)score,that is,the higher the dmfs score,the higher the ECOHIS score.Before treatment,ECOHIS scores in S-ECC group were significantly higher than that of CF group(p<0.01).After treatment,ECOHIS in S-ECC group was significantly lower than before treatment(p <0.01),and no significant statistical difference was found when compared with CF group(p > 0.05).Additionally,76.3% of the parents were satisfied with the effect of dental treatment under GA.Conclusion: The result shows that the OHRQo L of S-ECC children with dental anxiety was poor and it was significantly improved after treatment under GA.
