The purpose of this study was to investigate the effect of the height of remained coronal tooth structure on the retention of post and core. This study was directed to detect micro-separation after application of intermittent compressive force using India ink. 130 extracted human teeth were prepared for samples, and complete cast gold crowns were cemented with zinc-phosphate cement on the two types of post and core ; composite resin core with steel post, cast core and dowel. Conclusions were as follows : 1. Application of force to the crown on the tooth which lost coronal structure caused micro-separation between the tooth and the core. 2. The height of remained intact coronal tooth structure was effective to increase in the retention of post and core.
