Restoration of proximal contacts in decayed primary molars using three different matrix systems in children aged 5–9 years: An in vivo study

Abstract

Aims and objectives: Proximal contacts and their interdigitation through occlusal contact with opposing teeth play a major role in children, for the eruption of permanent teeth into normal position. Determining the ideal matrix band system for proximal restorations helps in the construction of contacts and contours. This study is designed to determine the most suitable matrix band system for proximal restorations. Materials and methods: A total of 96 proximal cavities were selected among patients aged 5–9 years and were equally divided into three groups. Group I: T-band, group II: ProMatrix, and group III: FenderMate. Pre-and postoperative radiographs were taken to evaluate carious lesions and restorations. Class II cavity was prepared and glass ionomer restorations were done using matrix systems. The efficacy of matrix bands was evaluated through the operator’s questionnaire and postoperative radiographs. Results: No statistical significance was found between the three matrix bands but FenderMate showed few clinical drawbacks that were statistically significant (p < 0.005). Interpretation and conclusion: Matrix systems used in this study showed good results in restoring proximal contacts and contours. FenderMate showed few drawbacks when compared with the other two matrix systems. None of the matrix systems used in the present study were able to create 100% accurate proximal contacts and contours.
