Abstract
Aims and Objectives: The aim of this work was to compare the fracture resistance values of Mesio-occlusal preparation, slot preparation with conventional grooves, box-only, and MOD preparation. Materials and Methods: A total of 60, noncarious extracted maxillary premolars were selected and divided into four groups, consisting of 15 teeth each -- group A: Mesio-occlusal preparation, group B: slot preparation (conventional grooves), group C: box-only preparation (long grooves), group D: MOD cavity preparation. All the specimens were subjected to compressive axial load in triaxial testing machine at a cross head speed of 1.2 mm/min at an inclination of 13.5°. Results: Group A (Mesio-occlusal) preparation had the least fracture resistance value and group D (MOD) cavity preparation had the highest fracture resistance. There was a significant difference in fracture load found between groups B and C. Conclusion: Amalgam restorations with Mesio-occlusal preparations had the least fracture resistance. Amalgam restorations with slot preparations had better fracture resistance than box-only preparation. Amalgam restorations with MOD preparations had the highest fracture resistance.
