Abstract

In the last decades researches in dentistry have shown increasing prevalence of dental erosion. Thus many types of treatment are proposed for these lesions and most of them are based on the remineralization of enamel,demineralized by acids not envolving bacterias. One of these elements is the casein phosphopeptide - amorphous calcium phosphate (cpp-acp), commercially named Recaldent©, that when incorporated into the chewing gum has the proposal to enhance the enamel remineralization. The purpose of this study is to assess the effect of CPP-ACP present in the chewing gum on in situ dental erosion. For this purpose, permanent teeth blocks will placed into a palatal appliance used by 12 previously selected volunteers. The trial presents four groups with the following conditions: GI -enamel subjected to erosive challenge untreated, GII - enamel subjected to erosive challenge treated with Trident Total© (CPP-ACP), GIII - enamel subjected to erosive challenge treated with Trident©, GIV - enamel subjected to erosive challenge treated with a unflavored Trident© . The study presents four phases of 7 days with an washout period of 7 days. In each phase the volunteer will immerse the palatal appliance in an acidic beverage 4 times a day for 5 minutes. The enamel changes will be analyzed by surface hardness and profilometry. The results will be submitted to appropriate statistical analysis considering the factor under study (type of treatment for remineralization and type of treatment for erosive cycling, both at three levels). The significance level will be 5%.
