Abstract

Objective

There is a need to determine whether total antioxidant capacity (TAC) in severe early childhood caries (S-ECC) is an indicator of inflammatory response to the lesion or a marker of the disease. This study compared TAC levels in children with ECC before and after dental treatment and compared the results with those of caries-free children.

Design

Prospective study.

Setting

A teaching hospital

Patient selection

Salivary samples were obtained from 20 children aged 5 years and diagnosed with S-ECC, and 20 age- and sex-matched controls.

Intervention details

Complete dental rehabilitation under general anesthesia was performed on the children with S-ECC, and follow-up salivary samples were obtained one week and three months postoperatively. TAC was measured using a commercially available Oxygen Radical Absorbance Antioxidant Assay measurement kit (Zen-Bio ORAC™, AMS Biotechnology, Abington, UK).

Outcome measures

Differences between children with and without dental caries were tested using the Mann-Whitney U test; differences before and after dental treatment were analyzed using Friedman test followed by Wilcoxon sign-rank test with Bonferroni correction to compensate for multiple comparisons.

Results

Median TAC (1.54 mcg/L, CI 1.15-1.92) of the control group was significantly lower than that of the treated group prior to treatment (p = 0.003). Treatment of the dental lesions significantly reduced TAC of the treated group, and no significant differences were observed between the test and control groups at either one week (p = 0.076) recall or three-month recall (p = 0.096). TAC in children posttreatment was significantly reduced compared to their pretreatment values (p < 0.001).

Conclusion

Total antioxidant capacity in the saliva of children with severe early childhood caries undergoes significant reduction following treatment of the carious lesions.
