Abstract

This study aimed to determine the influence of post space preparation with peeso reamers on the marginal integrity of a glass Ionomer cement (GIC) root end restoration. Thirty maxillary anterior teeth were disinfected, decoronated to obtain 16mm root lengths, cleaned shaped and obturated rising cold lateral compaction with AH Plus as the scaler: Teeth were divided into three groups of ten teeth each. In Group 1, the post space preparation was done first, followed by GIC retrograde restoration. In Group II , the GIC retrograde restoration was placed first, allowed to set completely and then followed by post space preparation. Group Ill served as the positive control. Teeth were coated with trail varnish and immersed in Rhodamine B dye for 4(s hours and microleakage assessed under 20X magnification rising a sterecomicroscope. Mean leakage of 1211.36 Um was recorded for Group I, 2088.63 Um for Group II and a complete leakage of 3000 Um far Group III. Significant difference existed between Group I & II (p<0.05) and a vets highly significant difference between Group I &III and Group Il & III. It was concluded that after complete setting of GIC, the vibrational energy of post space preparation is capable of disrupting its seal, when it is used for root end restoration.
