Consequences of 660 nm diode laser following postsurgical exodontia in patients under contraceptive pills: A randomized double blinded clinical trial

Abstract

Aim: The photobiomodulation (PBM) effect of 660 nm diode laser in reducing pain, edema, trismus and promote healing subsequently to the transalveolar extraction of mandibular third molars in female patients taking contraceptive pills were evaluated. Materials and methods: Fifty female patients participated in our study. The 660 nm diode laser was applied immediately on randomly selected patients of the study group (n = 25) over the surgical site for 1 minute with continuous laser beam application. For the control group (n = 25), the same extraction procedure was performed without the application of 660 nm diode laser. Pain intensity, swelling, trismus, and healing was evaluated before extraction and during recall visits 24 hours, 48 hours, and 7 days postoperatively. Results: The values of pain, swelling, and trismus were significantly inferior in the study group compared to the control group (p < 0.05) at T2 and T3; while the values of the healing index were significantly superior in the study group compared to the control group (p < 0.001) at T1, T2, and T3. Conclusion: Using 660 nm diode laser reduced the postsurgical discomforts (pain, edema, and trismus) and promote healing associated following transalveolar extraction of the lower third molar. Clinical significance: To develop a framework based on the results regarding the PBM effect of 660 nm diode laser following transalveolar extraction of lower third molar in a female patient taking oral contraceptive pills, which may help to improve the treatment services provided to the community.
