Micro-computed tomographic analysis of progression of artificial enamel lesions in primary and permanent teeth after resin infiltration

摘要

We investigated inhibition of lesion progression in artificial enamel lesions. Lesions were created on primary and permanent anterior teeth ( n = 10 each) and were divided randomly into two groups with two windows: Group 1 (window A: resin infiltration; window B: negative control) and Group 2 (window A: resin infiltration + fluoride varnish; window B: fluoride varnish). After pH cycling, micro-computed tomography was used to analyze progression of lesion depth and changes in mineral density. Resin infiltration and resin infiltration + fluoride varnish significantly inhibited progression of lesion depth in primary teeth ( P 0.05). Resin infiltration is a promising method of inhibiting progression of caries lesions. (J Oral Sci 57, 177-183, 2015)
