Abstract
To measure the microleakage of different materials used as temporary endodontic sealing materials and to compare between them. Sixty sound human premolars extracted for orthodontic purpose, caries and cracks free were used. Teeth were divided into 6 groups depending on type of temporary materials (glass ionomer cement, zinc phosphate cement, amalgam, temporary filling "zinc oxide eugenol") for temporization and control groups (negative and positive). For each tooth, an access opening was done followed by instrumentation, irrigation and dryness. Then application of different temporary materials. Evaluation of marginal microleakage (tooth – restoration interface) were done by using dye penetration test. The study was done in Department of Conservative Dentistry, College of Dentistry, University of Mosul. The results showed significant differences (p< 0.05) in marginal microleakage among groups tested. But there were no significant difference between buccal and lingual tooth restoration – interface for each group. Glass ionomer cement showed less microleakage at tooth – restoration interface when compared with other temporary filling materials which used in this study. Glass ionomer cement has superioer effect on reduction of microleakage when compared with other temporary filling,when used for temporization had more ability to reduce microleakage than zinc phosphate cement, amalgam and lastly temporary filling (zinc oxide eugenol).
