Oral health-related quality of life changes in children following dental treatment under general anaesthesia: a meta-analysis.

OBJECTIVE

To conduct a meta-analysis of studies that have employed the Early Childhood Oral Health Impact Scale (ECOHIS) and Child Oral Health-Related Quality of Life (COHRQoL) instruments, to evaluate the oral health-related quality of life (OHRQoL) changes in children following dental treatment under general anaesthesia (DGA).

METHOD

A systematic search of 5 databases was conducted in accordance with the PRISMA guidelines. The inclusion criteria were use of ECOHIS and COHRQoL, pre-and post-operative assessments, patients aged between 0 and 16 years, no restrictions on the follow-up period and DGA. The primary outcome measure was changes in quality of life for both the children, which was based on mean difference (MD). Twenty-two articles were included in the meta-analysis.

RESULTS

A favourable outcome in OHRQoL was identified in all studies. The combined MD for ECOHIS and COHRQoL were 1.62 [95% CI 1.52-1.71; P < 0.00001; I2 = 0%] and 0.86 [95% CI 0.74-0.99; P < 0.00001; I2 = 0%], respectively, both with no evidence of heterogeneity.

CONCLUSION

There is evidence to support that the OHRQoL of children was improved, with large effect size, in the short-term following DGA.

CLINICAL RELEVANCE

Dental treatment under GA significantly improved the OHRQoL of children.
