Abstract

ABSTRACT
Introduction: Early childhood Caries is a distressing situation for patients and
parents and pediatric dentists. Aim: current research was carried out to evaluate
fracture resistance and bond strength for different types of dentin posts compared to
fiber posts. Materials and Methods: This Current in-vitro study was conducted on
48 extracted primary incisors. Samples were split randomly into 4 groups of 12 for
each group. Group-I (fiber posts 6mm length, 1.4mm diameter), Group-II (dentin posts
6mm length, 1.4 diameter), Group-III (dentin posts 8mm length, 1.4mm diameter),
Group-IV (dentin posts 8mm length, 1.6mm diameter). Each group was further
subdivided into two subgroups (6 for the Push-Out bond strength test and 6 for the
fracture resistance test using Universal Testing Machine). Results: It was observed
in the fracture resistance test that, Group III showed the highest fracture resistance
means (140.678±11.98) followed by Group IV (131.38±7.03), Group-II (94.23±9.84),
and finally Group-I that showed the lowest fracture resistance means (80.465±2.82).
Push-Out bond strength test revealed that the highest mean value with Group-IV
(8.653±1.49), followed by Group-II (6.08±2.25) and Group III (5.67±2.44) have no
statistically significant difference between them, while the lowest mean value was for
Group-I. Conclusions: Dentin posts showed increased fracture resistance and bond
strength more than fiber posts. The use of dentin post as intra-canal retention in primary
anterior teeth possesses the most important advantages over the fiber post. Therefore,
biological dentin post is a successful alternative for fiber post.
