RESUMEN
<p><b>OBJECTIVE</b>To compare the clinical effect between reattachment of permanent anterior teeth with crown fracture using dual-cured resin combined with dentin pin and conventional method.</p><p><b>METHODS</b>49 permanent anterior teeth of 38 patients which had intact incisal edge segments were divided into two groups. In experimental group reattachment was conducted by dual-cured resin combined with dentin pin, while in control group only dual-cured resin was adopted. Cases were assessed clinically by one year's followed up.</p><p><b>RESULTS</b>The success rate was 95% in experimental group and 64% in control group after one-year's follow-up (P < 0.05).</p><p><b>CONCLUSION</b>The clinical effect of reattachment with dual-cured resin combined dentin pin to treat anterior crown fracture is superior to conventional method.</p>
