Abstract

Background: Preservation of primary incisors with extensive carious lesions represents a challenge in dental clinics. Extraction and replacement of these teeth by removable or fixed appliances may represent a big dilemma regarding gingival health and the patients Cooperation. Objectives: The aim of this study was to compare three various techniques used for restoring primary anterior teeth with extensive carious lesions regarding success and failure and mode of failure. Materials and Methods: About 30 children of both genders with ages 3 to 5 years participated in the study. The children were randomly divided into three groups according to post application technique, each group contained 10 children (20 central and lateral primary incisors). Group I: in which fiber post was cemented by dual-cured build up composite core. Group II: in which fiber post was cemented by dual cure resin cement. Group III: in which reverse metal post cemented by zinc phosphate cement. Results: Regarding success and failure by the end of follow up period, 20% of cases failed in group I (4 cases) while only 10 % of cases in group II (2 cases) and 15 % in group III (three cases) failed. Regarding the mode of failure among the studied groups, one case in group I and group II failed due to root fracture during the follow up period while 3 cases of failure in group III happened due to core fracture. Post deponding induce three cases of failure in group I and one case in group II.
