Application of LED light of the Blue-Violet Spectrum to induce Haemostasis Post Therapeutic Extractions-A Prospective Study

Author(s): Shivangi Gaur* and M Madhulaxmi

Abstract

Introduction: Therapeutic extractions are commonly performed for patients undergoing orthodontic treatment to achieve one or all treatment objectives as elaborated by Jackson’s triad. Although haemostasis can be achieved easily using conventional methods, a traumatic extraction techniques combined with various novel methods to control bleeding allow for minimal trauma to the investing tissues which is the prime concern in such cases. Hence, the aim of this study is to evaluate the efficacy of Light Emitting Diode (LED) curing lamps to cause photocoagulation of blood post extraction of teeth. Materials and Methods: The study included 20 patients who needed therapeutic extractions. They were divided into two equal groups namely control (Group A) and experimental (Group B). Conventional digital gauze compression was used in the control cases, while irradiation using Blue-Violet LED (Woodpecker i-LED) of the wavelength 420 ~ 480 nm, 1000mW/cm2 ~ 2500mW/cm2 for duration of 10 seconds was used for experimental cases. The time taken for bleeding of extraction sockets to arrest was noted. This data was tabulated and later statistically analysed using student t-test on SPSS 23.0 Student software. Results were drawn and conclusions were made. Results: The experimental group showed a shorter duration of bleeding as compared to the control group ie.12 seconds and 159.8 seconds, respectively. Experimental group was irradiated for 10 seconds in 80% cases, followed by 10 more seconds in 20% cases. Control group needed an average of 160 seconds for haemostasis performed by conventional method. Conclusion: Haemostasis can be satisfactorily achieved in systemically healthy patients using Blue-Violet LED curing lamp as the wavelength covers the absorption spectrum of haemoglobin (430 nm).
