Evaluation of Novel Glass Fiber-reinforced Composite Technique for Primary Anterior Teeth with Deep Carious Lesions: A 12-month Clinical Study

Abstract

Background: Early childhood caries discloses a distinct clinical pattern, and the teeth most often involved are the maxillary central incisors, lateral incisors, and the maxillary and man-dibular first molars. The maxillary incisors are most severely affected, with deep carious lesions usually involving the pulp. Teeth that have been endodontically treated often have little coronal tooth tissue remaining and as such require a post to retain the core and restoration .This study evaluated and compared the efficacy of EverStick glass fiber-reinforced composite post with ParaPost Taper Lux in primary maxillary anterior teeth.

Aim: An in vivo study was conducted to evaluate and compare the longevity and failures of two fiber post systems in primary maxillary anterior teeth.

Materials and methods: A total of 60 severely mutilated primary maxillary anterior teeth from children aged 3 to 5 years were selected according to the inclusion criteria. These teeth were treated endodontically and were randomly assigned into two groups with 30 samples in each group, group I: EverStick glass fiber-reinforced composite post, group II: ParaPost Taper Lux post. The evaluation of dislodgment of posts, secondary caries, root fracture, and post fracture was carried out clinically and radiographically during every follow-up at 3, 6, 9, and 12 months interval.

Results: Statistical tests (Chi-square test, Fisher's exact probability test) suggested that dislodgment of the posts was significant between the two groups at 6, 9, and 12 months follow-ups. But within the group during subsequent follow-up intervals, dislodgment of posts as a mode of failure was not statistically significant. However, clinically failures were seen in both the study groups.

Conclusion: Fiber post system has proved to be successful clinically in both primary and permanent teeth due to the mono-block effect with luting agent, post system, core material, and bonding to dentin. Thus, today the EverStick glass fiber post system provides a novel way of fabricating cost-effective and less time-consuming custom-made post in treating mutilated maxillary anteriors.
