Abstract
Recently, the non invasive intervention has become a part of a new era of dentistry aiming to control the demineralization and remineralization cycle, to minimize the surgical procedures in caries management and prevent the early lesions as erosion. This can be achieved by altering the oral environment, to achieve the balance in favor of remineralization rather than demineralization.
The purpose of this study was to compare the in vitro effect of acidic beverages (Cola and Orange juice) on surface microhardness and mineral content of primary versus permanent enamel pre-treated with remineralizing agents (Casein Phosphopeptide- Amorphous Calcium Phosphate and Acidulated Phosphate Fluoride gel).
A total of One hundred and eight teeth were used in this study (Fifty four crowns of deciduous molars and Fifty four crowns of permanent premolars). The crowns were embedded in acrylic resin mould with the labial or lingual enamel surfaces exposed.
All specimens of deciduous and permanent teeth were divided into three groups and subjected to remineralization process for 30 days, in which group 1 (deciduous and permanent groups) treated with CPP-ACP (GC Tooth Mousse), and group 2 (deciduous and permanent groups) treated with APF gel (Ionite), while group 3 (control groups) (deciduous and permanent control groups) received no treatment for 30 days. After thirty days, enamel surface microhardness of all the specimens was measured using Vickers microhardness tester and the mineral content was evaluated using EDAX analysis.
Then each group of the deciduous and permanent Groups (1,2, and 3) were divided equally into 2 subgroups and subjected to demineralization process for four days by Coke (Pepsi) and Orange juice (Beyti). After four days, enamel surface microhardness of all the specimens was re-measured using Vickers microhardness tester and the mineral content was re-evaluated using EDX analysis.
The microhardness results showed that there was an increase in microhardness values after remineralization followed by a slight decrease in the results after demineralization between the studied groups. This may indicate the ability of the two remineralizing agents used, to remineralize early carious lesions. However, elemental analysis showed no significant differences within or between groups through the experiment.
