IMPACT OF VARYING PH ON FLUORIDE RELEASE FROM DIFFERENT RESTORATIVE MATERIAL: AN IN VITRO STUDY

Dr. Parul Singh and Dr. Amit Kumar Khajuria*

ABSTRACT

Aim: Dental caries is one of the most prevalent chronic diseases affecting humanity. The use of fluoride releasing dental restorative materials have been increasing based on specific purpose of leaching of fluoride into the surrounding tissues to inhibit secondary dental caries as well as prevention of caries in the newly erupted tooth. Material and methods: 50 samples were prepared from each type of restorative material being tested. These 50 samples of each material are divided into 5 groups, 10 samples each group based on varying pH of the solution 4.2, 4.6, 5.0, 5.5 and 6.2 respectively. All the samples were subjected to alternate cycles of the demineralizing solution (6 h) and remineralizing solution (18 h) for 15 days. Results: Amalgomer CR showed highest fluoride releasing capability among all experimental restorative materials being tested. At pH 4.3, the fluoride release was highest and lowest at pH 6.2. Conclusion: Amalgomer CR based on its high fluoride releasing ability should be advised to pediatric patients with high risk of dental caries.
