Abstract

Introduction: Pulpal and periradicular diseases develop when microorganisms and/or their by-products contaminate these tissues. Therefore, the major goal of endodontic restoration is to prevent the penetration of microorganisms into the coronal pulpal space and root canal system. Objectives: To evaluate and compare the sealing ability of two intermediate temporary filling materials in badly destructed teeth reinforced with stainless steel bands and to evaluate the adaptation of these materials upon application of clamps and rubber dam material. Materials and methods: 65 mature maxillary premolar teeth were used in this study. This study was divided in two parts. Part I: evaluation of coronal leakage by glucose penetration model and spectrophotometer. Teeth were randomly divided into two experimental groups (n=10) and a control group (n=15). Access cavities and stimulation of loss of tooth structure were done. Instrumentation till apical size # 35 and reinforcement with stainless steel bands were done. Group I: teeth were filled with Cavit-G (3M ESPE, Seefeld, Germany); Group II: teeth were filled with CLIP (Voco, Cuxhaven, Germany); Group III: used as positive and negative control group. Measurement of coronal leakage was performed at the 3rd, 7th and 15th day. Part II: evaluation of adaptation of coronal restoration by using 2.5x magnifying loupes and USPHS criteria, grouping was done as before but ten teeth were used as positive controls. Results: Part I; CLIP (group II) showed the least glucose leakage with median change of leakage (1052.45) mg/dl followed by Cavit-G (Group I) with median change of (2828.55) mg/dl. The difference was statistically significant (P= 0.001). In part II; results were statistically significant (p=0.001), where the CLIP group showed better adaptation than Cavit-G group. Conclusions: CLIP seals against marginal leakage better than Cavit-G. CLIP provides better adaptation than Cavit-G on application of clamps and rubber dam.
