Calcium hydroxide as an activator in induced apexification

ABSTRACT

This study included 24 schoolchildren of both sexes aged 8-10 years with two traumatized pulpless immature upper anterior teeth. One tooth was filled with calcium hydroxide and compherated parachlorophenol [CPCP], against the other tooth as control canals dressed with CPCP only. Radiographic and clinical observations were used to evaluate the calcific changes, which were formed at the apex of the immature tooth. Apical barrier was detected at the end of the experiment of 15 months period in approximately 91.5% of cases filled with calcium hydroxide, while 1 of empty control canals showed an evidence of bridging at the apex
