Abstract

Background: severely damaged primary anterior teeth that require pulp therapy present a high-risk of failure due to the loss of tooth substance resulting from pre-existing decay and endodontic therapy itself. The ideal post material should have physical and mechanical properties that are similar to those of dentin . Another concern in restoring endodontically treated primary teeth is the need to find a material that can resorb in a similar way to natural tooth structure as a part of the exfoliation process allowing normal eruption of permanent successors . Accordingly there is no such material other than dentine itself.The introduction of Biological dentine posts offered an excellent alternative for restoring such teeth. The aim of the current study was to assess the effect of using dentine posts on the Pull Out resistance of endodontically treated primary anterior teeth in comparison to composite posts.

Materials and methods: A sample of 30 primary anterior teeth was collected from the outpatient clinic of Pediatric Dentistry Department, Faculty of Dentistry,Damascus University. 15 freshly extracted permanent teeth with single root were also collected from the outpatient clinic of Maxillofacial Surgery Department, Faculty of

Dentistry,Damascus. University. The roots of the permanent teeth were used to prepare 30 dentine posts using CAD-CAM machine. After receiving proper endodontic treatment, the primary teeth were divided into two groups (15 teeth in each group). The first group was restored with dentine posts, and the second group was restored with composite posts 3 mm in length for both groups. Pull Out resistance testing was performed using Testometric machine.

Results: The results were recorded.descriptive statistics were performed and the data were analyzed at 95% confidence interval using independent t-student test. There were no statistically significant differences in Pull Out resistance between the two groups. But Dentin posts showed increased in Pull Out resistance (156,7) N more than composite posts (149,7) N.

Conclusion: Dentin posts showed increased in Pull Out resistance (156,7) N more than composite posts (149,7) N. Therefore, the use of dentin posts as intra-canal retention in primary anterior teeth is a successful alternative for composite posts.
