Abstract:
UNASSIGNED: Low-level laser therapy (LLLT) has shown benefits as an alternative treatment of feline chronic gingivostomatitis by reducing pain and inflammation within the oral cavity. Extraoral application technique in cats provides more comfort compared to intraoral application. However, the efficacy of LLLT through buccal tissue is still controversial. This study aimed to investigate the penetration efficacy of LLLT using 830 nm continuous waves with various settings and different application techniques.
UNASSIGNED: Twenty-four healthy cats were included in this study. The wavelength of LLLT was 830 nm with an output power of 200 mW through extraoral application, using fluences of 2 and 6 J/cm2 in continuous-wave mode. This study compared different distances (contact and non-contact) and three different transmission media (absent media, alcohol, and normal saline solution). Measurement of the laser power within the oral cavity is represented as the mean output power (MOP).
UNASSIGNED: Penetration efficacy was detectable for all fluences, distances, and transmission media, with an average buccal thickness of 2.68 mm. MOP did not differ between fluences of 2 and 6 J/cm2 (p = 0.19). In the absence of media, MOP was significantly higher compared with alcohol (p < 0.05) but was not significantly different from normal saline solution (p = 0.26).
UNASSIGNED: Extraoral application of LLLT demonstrated penetration efficacy through the buccal tissue with both contact and non-contact skin (<10 mm). This is a potential alternative treatment for oral diseases in clinical practice. However, there is a need for further study on the efficacy of treatment in clinical practice.
摘要:
低水平激光治疗(LLLT)通过减少口腔内的疼痛和炎症,已显示出作为猫科动物慢性牙龈炎的替代疗法的益处。与口内应用相比,猫的口外应用技术提供了更多的舒适度。然而,LLLT通过颊组织的疗效仍存在争议。本研究旨在研究使用具有各种设置和不同应用技术的830nm连续波的LLLT的穿透功效。
本研究包括24只健康猫。通过口外应用,LLLT的波长为830nm,输出功率为200mW,在连续波模式下使用2和6J/cm2的通量。本研究比较了不同的距离(接触和非接触)和三种不同的传输介质(无介质,酒精,和生理盐水溶液)。口腔内激光功率的测量表示为平均输出功率(MOP)。
所有注量的渗透功效均可检测到,距离,和传输介质,平均颊厚度为2.68毫米。MOP在2和6J/cm2的注量之间没有差异(p=0.19)。在没有媒体的情况下,与酒精相比,MOP显着较高(p<0.05),但与生理盐水溶液没有显着差异(p=0.26)。
LLLT的口外应用证明了通过接触和非接触皮肤(<10mm)的颊组织的渗透功效。这是临床实践中口腔疾病的潜在替代疗法。然而,在临床实践中需要进一步研究治疗的疗效。
