Aim: This study was designed to compare the relative efficiency of nanohydroxyapatite (n-Hap) Aclaim, n-HAp Apagard, Clinpro Tooth Crème and Colgate Total in remineralization. Settings and Design: One hundred and eight healthy maxillary first premolars devoid of decay, restoration, and attrition were used. Materials and Methods: Stainless steel premolar brackets were bonded on all the teeth. The teeth were randomly assigned into three groups and subgroups of 12 teeth each. The samples of each group were immersed separately in an artificial saliva solution for 23 h and acid solution for 1 h for 31 days, following by sectioning and observing under polarized light microscope. The depths of the demineralized enamel in each experimental and control section were measured at three sites of the gingival demineralized area. The first site D1, near the gingival margin, the second site D2 at middle third and the third site D3 near the occlusal margin of the gingival demineralized area. Statistical Analysis: One-way analysis of variance and Tukey test were used. Results: Aclaim and Apagard were most efficient in prevention of demineralization. Maximum depth of demineralization was observed at site D2. Conclusions: Aclaim and Apagard on daily application will provide maximum protection against enamel demineralization in orthodontic patients.
