Abstract

ABSTRACT
Objective of this study is to evaluate clinically and radiographically the calcium – hydroxide formocresol mix as a root filling material in primary teeth .
Materials & Methods: The study was performed on 75 primary molars of patients aged from 4-8 years that indicated for pulpectomy. The teeth were divided randomly into 3 main equal groups. Each group formed of 25 primary molars. Group A: 25 children teeth in which zinc oxide and eugenol (ZO/E) was used as filling material . Group B: 25 children teeth in which calcium hydroxide formocresol mix was used as a filling material. Group C : 25 children teeth In which matapex was used as filling material . The teeth were assessed clinically and radiographically at 5 different intervals (preoperative, 24 hours, 6 weeks , 3 months and 6 month postoperative), using standard clinical and radiographic criteria. Results: It was found that Maetapex offers best clinical and radiographical results when compared with ZO/E and calcium hydroxide fromocresol mix . ZO/E (group A) showed (84%) success rate, while the Calcuim hydroxide fromocresol mix (group B) showed a higher success rate (88%) than (ZO/E) . Metapex (group c) show best success rate of all groups (94%) while failure rate showed (16%) , (12% ) and (6%) respectively. Conclusion: Metapex is the best material as root filling material with a high success rate and showing competitive properties to ZO/E and Calcium hydroxide formocresol mix . calcium hydroxide formocresol mix shows better result than ZO/E .
