Abstract

Background: Limitations of dental composite have dictated the need for development of new self-healing composite. Aim: To evaluate the effect of adding an experimentally prepared glass ionomer-based microcapsule to commercially available flowable composite on its fracture toughness and healing crack efficiency. Methodology: Seventy composite specimens were divided into two groups according to the material used, group C: as-received commercially available flowable composite while group HC: commercially available flowable composite modified by adding experimentally prepared self-healing microcapsule. Preloading of the specimens with a fixed load (60 N) was done before the storage period. The fracture toughness (K_IC) was measured for each group after three days of water storage. The crack healing efficiency of HC group was also evaluated mechanically, chemically and morphologically. Results: Group HC revealed a statistically significant higher fracture toughness when compared to that of group C after three days of water storage.
