Comparative evaluation of the Treatment Efficiency of Endo−Perio Lesions Using a Standard Treatment Protocol and Extended by Using a Diode Laser (940 nm)

Abstract

Background

Endo-perio lesions pose a significant challenge in dental practice due to their complex etiology and the intricate relationship between the pulp and periodontal tissues. Conventional treatment protocols often yield inconsistent outcomes. The incorporation of diode lasers, particularly at a wavelength of 940 nm, has shown promise in enhancing treatment outcomes due to their bactericidal, biostimulatory, and decontaminating properties. This study evaluates the treatment efficiency of standard protocols compared to those augmented with a diode laser.

Materials and Methods

This clinical trial included 40 patients diagnosed with endo-perio lesions, divided into two groups of 20 each. Group A received conventional treatment comprising root canal therapy and scaling and root planing, while Group B received the same protocol extended with 940 nm diode laser application. Clinical parameters such as probing pocket depth (PPD), clinical attachment level (CAL), and radiographic bone density were recorded at baseline, 4 weeks, and 8 weeks post-treatment. Statistical analysis was performed using paired t-tests and ANOVA, with significance set at p< 0.05.

Results

At 8 weeks, Group B demonstrated significantly better outcomes. Mean PPD reduction was 3.2 ± 0.5 mm in Group B compared to 2.1 ± 0.4 mm in Group A (p = 0.001). CAL improvement in Group B was 3.5 ± 0.6 mm versus 2.4 ± 0.5 mm in Group A (p = 0.002). Radiographic analysis revealed a 20% increase in bone density in Group B, compared to a 12% increase in Group A.

Conclusion

The adjunctive use of a 940 nm diode laser in the treatment of endo-perio lesions significantly enhances clinical outcomes compared to standard treatment protocols. This approach may represent a superior therapeutic modality in managing these complex conditions.
