Background: In clinical practice, achieving an ideal contact point replication in class II cavities is crucial. This study aims to assess the impact of two matrix band systems on proximal contacts while reconstructing the class II cavities in permanent posterior teeth.
Patients and methods: This trial was conducted in the Operative Dentistry Department at PIMS Hospital Islamabad. The sample size was 80, with 40 in each group, Group A (circumferential matrix) and Group B (sectional matrix). Supra gingival class 2 cavity limited to dentine with fully erupted permanent posterior teeth were included. Chi-square and Pearson's correlation were carried out to assess the relation between the matrix band and proximal tooth contact, and proximal overhanging margin.
Results: Findings revealed that there was a significant association between the proximal contact points in both groups (p-value = 0.00) and there is no statistically significant link between the presence of an overhanging margin and the occurrence of open, tight, or ideal contact points(r = 0.19, P>0.088).
Conclusion: The sectional matrix band proved to be more effective than the circumferential matrix band when it came to repairing the class II cavities proximal contact in permanent posterior teeth.
