Microleakage Evaluation and Fracture Resistance of Pulpotomized Primary Molar Restored with Fiber-Reinforced Composite with and without Stainless-Steel Crown (In-Vitro Comparative Study)

Objectives: the objective of the current study was to assess the microleakage and fracture resistance of pulpotomized primary molars that were rebuilt with fiber-reinforced composite and either had or did not have a stainless-steel crown. subjects and methods: 96 carious primary molar teeth were categorized into four groups; the first group; primary molar teeth restored with fiber reinforced composite, the second group; primary molar teeth restored with fiber reinforced composite and stainless-steel crown, the third group; primary molar teeth restored with composite, the fourth group; primary molar teeth restored with composite and stainless-steel crown. Microleakage and fracture resistance were assessed. Results: lower microleakage values were recorded in teeth restored with stainless-steel crowns, and the higher microleakage values were recorded in teeth restored without stainless-steel crowns. the higher fracture resistance values were recorded in teeth restored with stainless-steel crowns, and the lower fracture resistance values were recorded in teeth restored without stainless-steel crowns. However, the teeth restored with fiber reinforced composite showed higher significant fracture resistance values when compared with the teeth restored with composite. Conclusion: SSC has received a high recommendation for primary molars that have undergone pulp treatment. FRC is advised in situations where parents have cosmetic concerns, provided that dental health is preserved.
