| Abstract | ||
| Background: Calcium Hydroxide preparations are used extensively in dentistry, and one of these aspects is treatment of root perforations. The purpose of this in vitro study was to compare the sealing ability of a prisma (visible light cure dycal), amalgam with varnish and chemical cure dycal are used to repair lateral root perforations. Materials and Methods: Thirty extracted human maxillary anterior teeth were used; each tooth was sectioned longitudinally into facial and palatal halves .The perforations were made into each half tooth at the cervical third of the root. The samples were divided into three groups; group I was repaired with prisma, group II repaired with chemically cured dycal and group III with varnish and amalgam .The teeth halves were placed in methylene blue dye for one week period then linear dye penetration was measured from where the repair materials were made. Results: The results showed that a prisma (visible light cure dycal) demonstrated less dye penetration than other groups, the difference was statistically significant (p<0.01) from other groups, non significant differences (p>0.05) were present between amalgam with varnish and the chemically cured dycal. Conclusion: Calcium Hydroxide including the visible light cured and the chemically cured, and the amalgam with varnish, each possess a therapeutic potential for treating known and undetected root perforations. Percentage of leakage was more in amalgam with varnish group than prisma and Kerr Dycal | ||
