Abstract

<p>Abstract : The purpose of this study was to evaluate the effects of a light-activated calcium hydroxide on the new hard tissue formation at the orifice and the pulpal stimulation after pulpotomy.</p><p> Twenty teeth of two adult beagle dogs were used. The coronal pulp was mechanically removed with #3 round bar, after which the orifice was dressed with a calcium hydroxide pastes containing saline, or light-activated calcium hydroxide (Ultrablend). The animals were sacrificed one week, one month and three months after operation, and histopathologically evaluated.</p><p> The result were as follows :</p><p> The formation of new hard tissue in light-activated calcium hydrtxide was less than that in the calcium hydroxide paste. Beside in the three-month cases of light-activated calcium hydroxid, inflamation remained in pulp.</p>
