Abstract
ABSTRACT
Background
Caries process is not a static one, but is dynamic with interspersed periods of
demineralization and remineralization of enamel, intimately related and occurs
episodically based upon the presence of cariogenic bacteria in dental plaque and
the availability of refined carbohydrates for fermentation to organic acids.
Objectives
Early enamel caries could be reversed with avoidance of frank cavitation. The
main objective of this study is to check wether enamel demineralization can be
prevented by using the remineralizing agents.
Method
Forty freshly extracted human central incisors were selected and stored in saline
at normal temperature. A window of 3 X 3mm enamel was created and all the
specimens were then randomly divided into 4 groups of 10 each. Group I- teeth
received no treatment, Group II- teeth treated with Acidulated Phosphate Flouride
gel, Group III- teeth treated with Tooth Mousse Plus, Group IV- teeth treated with
Remin+. Samples in all the groups were kept in artificial saliva for 24 hours and
subjected to modified Ten Cate’s solution at an acidic pH of 3.5 for 10 days. The
samples were sectioned and subjected to SEM evaluation.
Result
Scanning Electron Microscope(SEM) images showed decrease in pore volume of
the enamel in all the treatment groups compared to the control group indicating
increase in resistance to demineralization in acidic pH.
Conclusion
The three groups of remineralizing agents, Acidulated Phosphate Fluoride gel,
Tooth Mousse Plus and Remin + showed significant increase in fluoride content and
negligible increase in calcium content indicating there is remineraliztion.
