The purpose of this study was to compare of the effectiveness by hydroxyapatite (HAp) and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) containing paste on bleached enamel. Seventy-two bovine enamel blocks were prepared and randomly divided into two groups: distilled water (D·W), 30% hydrogen peroxide. And thirty-six bleached enamel block were divided into three groups: Bleached enamel after distilled water, Bleached enamel after hydroxy apatite paste , Bleached enamel after CPP-ACP paste. The samples were analyzed qualitatively by evaluating morphological changes in the SEM images, microhardness and quantitatively by using roughness parameters (Ra). The acquired data was analyzed by paired t-test and one-way ANOVA followed by Tukey s multiple test for variable at a 0.05 significant level. All the samples showed decrease in the microhardness after two cycles of bleaching, though immediately after bleaching the decrease in the microhardness was significant (p<0.05). Bleached enamel surface of two remineralizing paste groups showed any apparent morphology and roughness changes compared to the enamel which was stored in distilled water only. HAp and CPP-ACP containing paste used in the study causes an increase in the microhardness of bleached enamel by maintaining a high gradient of calcium and phosphate ions at the enamel surface. HAp and CPP-ACP containing paste has the potential to remineralize on bleached enamel.

The purpose of this study was to investigate the effects of oral health education experi-ence and interest in oral health on university students’ oral health behavior and oral health knowledge. This study was conducted with the purpose of demonstrating that proper oral health edu-cation programs should be developed in order to improve oral health management behavior. With regard to teeth brushing habits, the oral health care behavior of the subjects was of an overall high average value. Average figures relating to diet and prevention questions was similar. However, the average number of oral hygiene items came out lowest. Although it is good practice to brush up on oral hygiene, behavior related to oral hygiene was relatively poor. The subjects’ level of oral health knowledge contained the three items with the highest percentage of correct answers: ‘Tongue should be wiped when brushing’, ‘Brushing should be done by rotation (teeth from top to bottom and teeth from bottom to top)’, ‘Fluoride eliminates bad breath’, ‘Toothbrushes should be replaced with a new one within 3 months’, and ‘Knowledge of brushing’. The knowledge level of fluoride and oral hygiene products was low. The study demonstrated that those with a greater experience of oral health education took better oral health care, in terms of brushing and prevention. However, behavior in terms of diet and food showed almost no difference and it was hard to find patterns of good behavior. Experience in oral health education has led to a high level of ‘interest’ oral health care.
