A preliminary study on the effect of photobiomodulation with diode laser on direct pulp capping of cariously exposed teeth
Year: 2025
Type: article
Abstract: Background: Vital pulp therapy has gained significant attention in modern clinical practice. However, direct pulp capping (DPC) success rates remain low due to bacterial contamination. Aims and Objectives: This study explored novel techniques of preoperative disinfection and photobiomodulation with diode laser to enhance outcomes. Materials and Methods: Forty patients were divided into two groups: Group A: Calcium hydroxide pulp capping, Group B: Preoperative disinfection with sodium hypochlorite (one minute) + photobiomodulation with diode laser + composite restoration. Statistical Analysis: Cochran's Q Test compared pain, tooth sensibility, and radiographic changes at 1, 3, and 6 months (p<0.05). Results: The study yielded success rates of 80% and 90% for groups A and B, respectively. Group B showed increased success rates, although not statistically significant which can be attributed to the laser's biostimulation properties. Conclusion: This study suggests that combining preoperative disinfection and photobiomodulation with diode laser may improve DPC success rates, offering a promising approach in vital pulp therapy. Further research is warranted to confirm these findings.
