Abstract

Aim of the Study: Contemporary dentistry faces an ongoing challenge in achieving natural-looking anterior restorations. This investigation sought to determine the effectiveness of three distinct approaches to shade matching when restoring fractured incisal angles in maxillary incisors: traditional polychromatic layering, contemporary monochromatic single shade, and universal body shade techniques. Materials and Methods: Researchers recruited 48 individuals presenting with fractured incisal angles in vital maxillary permanent incisors for this randomized clinical trial. Through random allocation, participants received one of three restoration methods using Charisma® Diamond composite: layered polychromatic technique, single-shade monochromatic approach, or universal body shade restoration. A VITA Easyshade® V spectrophotometer enabled precise color measurements before and following restoration, with researchers examining variations in luminosity (ΔL), red-green balance (Δa), blue-yellow spectrum (Δb), and overall color deviation (ΔE). Results: Analysis revealed that traditional polychromatic layering achieved remarkably natural results, demonstrating the smallest color deviation (ΔE = 3.88±1.43). Universal body shade technique showed comparable effectiveness (ΔE = 5.47±2.41), while the monochromatic approach resulted in notably higher color disparity (ΔE = 10.70±5.82, p<0.001). Interestingly, brightness values (ΔL) remained consistent across all techniques (p=0.121), though red-green and blue-yellow parameters showed meaningful variations between the monochromatic method and its counterparts. Conclusion: These findings suggest that while both layering and universal body shade techniques can deliver aesthetically pleasing outcomes, the monochromatic approach may present limitations in achieving optimal color harmony. Clinical Recommendation: Dental practitioners should weigh various factors including clinical presentation, desired aesthetic outcomes, and technical expertise when selecting between layering and universal body shade approaches.
