META-ANALYSIS OF MAX GLASS CERAMIC OVERLAYS FOR RESTORING RESIDUAL ROOT CROWNS IN SPORTS-RELATED DENTAL INJURIES

Abstract

Objective: This meta-analysis evaluates the efficacy of Max glass ceramic overlays in the restoration of residual root crowns, particularly in athletes who often face sports-related dental injuries. Methods: Relevant randomized controlled trials were sourced from databases such as PubMed, Cochrane Library, EMbase, CNKI, Wanfang, and Chinese biomedical literature up to March 2023. Two independent researchers extracted data, resolving discrepancies through consensus with a third researcher. Data were analyzed using RevMan version 5.2.7 software, employing a fixed-effects model. Four randomized controlled trials comparing Max glass ceramic overlays with other dental restoration materials were included. The meta-analysis showed that Max glass ceramic overlays significantly enhance the integrity of dental restorations and the remaining tooth structure, with a relative risk (RR) value of 0.51, 95% CI: [0.31, 0.82], and a P-value of 0.005, indicating substantial statistical significance. Additionally, Max glass ceramic overlays demonstrated a lower incidence of gingival edge staining compared to alternative materials, with RR=0.13 and 95% CI [0.04, 0.38], and a P-value of 0.0002. Egger's test indicated slight publication bias (P=0.502). Conclusion: Max glass ceramic overlays provide superior restoration integrity and better preservation of residual tooth structure compared to other materials used in the dental restoration of athletes. This material also reduces the risk of gingival edge staining, making it a preferable option for managing sports-related dental injuries. These findings support the broader adoption of Max glass ceramic overlays in sports dentistry to ensure robust, long-lasting dental repairs in athletic populations.
