“…The examination group showed almost immediate bleeding stop after applying LED light, compared to the control group. These findings are very similar to the findings from author Isao Ishikawa et al, which tested the effects of LED on postoperative bleeding in oral surgery [ 11 ]. The duration of the irradiation needed to stop the bleeding in our study was also similar to his results.…”

“…The first phase consists of heating effects, followed by formation of spherocytes and met-haemoglobin. Finally, extended coagulum formation happens due to spherocyte rupture [ 11 ]. Thermal damage and carbonisation of the underlying soft and hard tissues could be possible complications after laser irradiation [ 15 ].…”

“…The transmission electron microscopy of the blue-violet LED irradiated blood clot found out a unique structure of the clot (photothermal interaction with the blue-violet LED). On the surface of the LED irradiated clot, there was a thin amorphous layer of denatured plasma proteins (about 50-1500 nm) [ 11 ]. This amorphous layer is clinically presented as a shiny surface of the LED irradiated blood clot.…”

BACKGROUND:The invasive dental procedures usually result in wounds accompanied by physiological bleeding. Even though the bleeding is easily manageable, it is still one of the major concerns of the patients and a reason for their subjective discomfort. Recently, a novel approach with light-emitting diode (LED) was introduced to control the bleeding. This study aims to examine the effectiveness of the irradiation with blue-violet light LEDs on the haemostasis.MATERIAL AND METHODS:The study included 40 patients with an indication for tooth extraction, divided into two groups: examination group (n = 30) and a control group (n = 10). The site of the extraction socket in the examination group was irradiated with LED (410 nm) until the bleeding stopped. The patients from the control group were treated by conventional gauze pressure to stop the bleeding (control group). The duration of irradiation and gauze pressure was measured and compared. The statistical analysis was performed with Student T-test.RESULTS:The examination group showed the shorter duration of bleeding compared to the control group for 13.67 seconds and 156 seconds, respectively. The most of the cases in the examination group were irradiated in 10 seconds (70%), followed by irradiation of 20 seconds (23.3%) and 30 seconds (6.6%). In the control group, the average time to stop the bleeding by the conventional method was 156 second.CONCLUSION:The blue-violet LED light shortens the bleeding time from the extraction socket after tooth extraction and may be a promising method for achieving haemostasis.

“…These devices are more compact and portable and considerably less expensive compared to lasers (Takasaki et al 2009). Another advantage of LED is that its irradiation is less harmful to the eyes than laser irradiation (Ishikawa et al 2011). Previous in vitro study showed that LED-based PAD could effectively reduce the inflammatory response of macrophages to Porphyromonas gingivalis lipopolysaccharide adherent to titanium surface (Giannelli et al 2011).…”
