Abstract
Objective: To compare the marginal integrity of Class-1 restorations with Spectrum TPH-3 vs Nexcomp in mandibular molars. Study Design: Quasi-experimental study. Place and Duration of Study: Operative Dentistry Department of Armed Forces Institute of Dentistry (AFID), Rawalpindi, Pakistan, from Sep 2020 to May 2021. Methodology: A total of 60 candidates were enrolled and allocated randomly to one of two groups, A and B. Group-A received spectrum TPH3 and Group-B received Nexcomp composite. Patients were followed up after 2 and 6 months for evaluation of marginal fractures with the help of loupes, probes, mouth mirrors and bitewing radiographs. Result: The rate of marginal fractures in Nexcomp were greater (27% at 2 months and 30% at 6 months) as compared to Spectrum TPH3 (73% at 2 months and at 77% 6 months) yielding a statistically significant difference between the two groups (p value= 0.004 and 0.001). Conclusion: Spectrum TPH gives a better quality of posterior restoration as compared to Nexcomp, contributing positively towards better quality of oral health for patient.
