ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the marginal adaptation between the new nano-hydroxyapatite composite resin and tooth.</p><p><b>METHODS</b>Thirty extracted healthy premolars were randomly assigned to three groups according to the material employed New nano-hydroxyapatite composite resin (Group A), Karisma composite resin (Group B), and glass ionomer cement (Group C). After the thermal cycling, the teeth were immersed in 2% methylene blue dye, and the depth of microleakage between the composite and tooth structure were observed.</p><p><b>RESULTS</b>The microleakage depth of group A, B and C were (1.20+/-0.81), (1.94+/-0.70), and (1.73+/-0.54) mm, respectively. No statistically significant differences were found among the three groups (P>0.05). There was no significant difference in the degree of microleakage (P>0.05).</p><p><b>CONCLUSION</b>As a new dental restorative material, new nano-hydroxyapatite composite resin has good bonding performance to the tooth structure.</p>
