Summary:The effects of three materials on the biological repair of a defect created by perforating the pulp chamber floor of mandibular posterior teeth in dogs was studied clinically and histologically. The three materials used were tricalcium phosphate, calcium hydroxide, or Teflon discs. The calcium hydroxide caused a more destructive reaction than did the Teflon or tricalcium phosphate groups. The size of the tooth in relation to the size of the perforation was directly proportional to the prognosis; larger teeth had the best results. Se estudiaron clínica e histológicamente los efectos de tres materiales sobre la reparación biológica de perforaciones prefabricadas mecánicamente en el piso de la cámara pulpar en dientes inferiores posteriores de perros. Los tres materiales usados fueron fosfato tricálcico, hidróxido de calcio y discos de Teflón. El hidróxido de calcio provocó una reacíon más destructiva que los grupos con Teflón o fosfato tricálcico. El tamaño del diente en relación tamaño de la perforación fue directamente proporcional al diagnóstico; en los dientes más grandes se obtuvieron mejores resultados.
