The aim of this study was to compare the effect of Caseinphosphopeptide-amorphous calcium phosphate (CPP-ACP) paste and Fluoride gel on the microhardness of demineralized enamel lesions.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Methods: </i></strong>Frothy eight specimens of premolar teeth were chosen and randomly divided to 4 groups of 12. After the initial measurement of micro-hardness the specimens were immersed in demineralizing solution for 4 day and then the measurements were recorded again. Two groups (GL and G3) were treated with CPP-ACP and Fluoride gel respectively according to manufacturer’s<sup style="margin: 0px padding: 0px border: 0px"> </sup>instruction. Two other groups (G2 and G4) were treated with CPP-ACP and fluoride gel every week for three months. After the treatments all specimens were taken into PH-cycling and the micro-hardness for each one were measured again. For data analysis, the Repeated Measures ANOVA test and the LSD tests were performed. In each group the percentage of micro-hardness recovery was measured.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Results: </i></strong>Repeated Measures ANOVA and LED Test showed that the mean value of hardness was significantly decreased after demineralization in all groups (p=0.01). There was no significant difference in mean hardness value in groups (GL, G3) after treatment (p=0.1, p=0.12) In groups (G2,G4) the mean hardness value were significantly increased (p<0.0001, p=0.1). It is noticeable that the CPP-ACP was significantly more efficient than the fluoride gel.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Conclusion: </i></strong>CPP-APC paste and fluoride gel both increase the micro-hardness of enamel when administrated for long time and repeated application.</p><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Journal of Dental School Shahid Beheshti University of Medical Sciences </p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://jds.sbmu.ac.ir/browse.php?a_id=1376&sid=1&slc_lang=en" target="_blank"><font color="#0000ff">Full Text</font></a></p> Dental Enamel, Private office, Tooth Demineralization, Tooth Remineralization, 0 0 http://idai.ir/browse.php?a_code=A-10-32-2949&slc_lang=fa&sid=1 Leila Pishehvar 100319475328460013711 100319475328460013711 No Dept. of Operative Dentistry, Dental School, Khorasgan Branch, Islamic Azad University, Isfahan, Iran Romina Mazaheri 100319475328460013712 100319475328460013712 No Dept. of Pediatric Dentistry, Dental School, Khorasgan Branch, Islamic Azad University, Isfahan, Iran Mahboobeh Mirzakhani mahboobeh_mkh@yahoo.com 100319475328460013713 100319475328460013713 Yes Dept. of Operative Dentistry, Dental School, Khorasgan Branch, Islamic Azad University, Isfahan, Iran Mohammad Hassan Nazari 100319475328460013714 100319475328460013714 No Fatemeh Sadat Ranjbaran 100319475328460013715 100319475328460013715 No Dept. of Operative Dentistry, Dental School, Khorasgan Branch, Islamic Azad University, Isfahan, Iran.
