Abstract
Background: This study is to compare between Amalgam and Mineral Trioxide Aggregate as retrograde filling in the healing process of periapical surgery by clinical and radiographical evaluation. Material and method: A follow up study of twenty patients, eleven were females, nine were males, of average age (12-36) years old, with forty upper central incisors involved with chronic periapical lesions, each patient has two central incisors with two separated periapical lesions, the right side was apically filled with Zinc free Amalgam and named as a control group (Group A), and the left side was filled with MTA as a study group (Group B). All patients were recalled within three months and six months, and subjected to clinical and radiographical examinations, to evaluate the healing process of both groups. Results: Clinically the study shows three failure cases (7.5%), one case (2.5%) was objectively failure which shows sinus formation in Amalgam group and two cases (5%) were subjectively failure, which shows pain and tenderness, one case in each group. Radiographically, the study reported a remarkable bone formation 27 cases (67.5%), fifteen cases in MTA group and twelve cases in amalgam group after six months. While 10 cases (25%), showed delayed bone formation, four cases were in MTA group and six cases were in Amalgam group, and three cases (7.5%) were showed enlargement in the size of radiolucency, one case in MTA group and two cases in Amalgam group. According to the follow up during the six months, the MTA group showed higher successful rate than Amalgam group, and the failure cases in group A was 10% and 5% in group B. Conclusions: The study shows that the best results are in those patients who have failure in root canal filling, and in those patients who did not have labial sinus formation and labial cortical bone perforation. MTA group, shows decreased in (Mesio-Distal, Superio-Inferior dimensions and cavity surface area), faster than the Amalgam group.
