Abstract
Objective: To assess remineralization of primary teeth enamel under the presence of fluoride, calcium and phosphorous ions using microhardness and surface roughness testing.
Design: Artificial caries lesions were created in enamel surface of 144 human primary molars. Specimens were randomly assigned according to remineralizing agent into six groups: 1) Artificial saliva, 2) Fluoride varnish, 3) Clinpro (TM) white varnish, 4) Relief, 5) Tooth Mousse Plus, 6) Vanish(XT)TM. Surface micro-hardness and surface roughness were evaluated at baseline, after demineralization, after 2 and 4 weeks remineralization and after exposure to acid challenge.
Results: All test groups showed superior results to the control. The surface micro-hardness of Clinpro (TM) group by 4 weeks remineralization showed statistically the highest value with the least softening as exposed to acid challenge. Concomitantly, by 4 weeks remineralization, Clinpro (TM) agent was able to regain enamel surface roughness incomparable to that of baseline value statistically the least of test groups.
Conclusion: Calcium-phosphate and fluoride remineralizing systems possess added remineralization potency in comparison to artificial saliva. Clinpro (TM) varnish showed the greatest remineralizing action and the least softening by acid challenge. (C) 2017 Japanese Society of Pediatric Dentistry. Published by Elsevier Ltd.
