Efficacy of Different Dentin Posts for the Treatment of Primary Anterior Teeth (An In vitro study)

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. INTRODUCTION Crown damage of primary anterior teeth is a frequent issue in pediatrics dental clinics because of either early childhood caries (ECC) or trauma (1). ECC is a quickly progressing developing type of dental caries that occurs primarily in the cervical third of maxillary incisors till full damage of the crown. It principally affects the primary maxillary incisors shortly following the eruption of teeth and infects other primary teeth quickly causing early tooth loss (2). In primary teeth, gaining intracanal retention through posts is tricky due to that permanent teeth need to find a way for primary counterparts. To ensure well-timed eruption of permanent successors in normal undeflected places, the intracanal post would timely resorb way (3). DOI: 10.21608/dsu.2021.58163.1059 Manuscript ID: DSU-2101-1059
