The fundamental pathophysiologic response for the survival of all organisms is the process of wound healing. Inadequate or lack of healing constitutes the etiopathologic basis of many oral and systemic diseases. Among the numerous efforts to promote wound healing, biophotonics therapies have shown much promise. Advances in photonic technologies and a better understanding of light-tissue interactions, from parallel biophotonics fields such as in vivo optical imaging and optogenetics, are spearheading their popularity in biology and medicine. Use of high-dose lasers and light devices in dermatology, ophthalmology, oncology, and dentistry are now popular for specific clinical applications, such as surgery, skin rejuvenation, ocular and soft tissue recontouring, and antitumor and antimicrobial photodynamic therapy. However, a less well-known clinical application is the therapeutic use of low-dose biophotonics termed photobiomodulation (PBM) therapy, which is aimed at alleviating pain and inflammation, modulating immune responses, and promoting wound healing and tissue regeneration. Despite significant volumes of scientific literature from clinical and laboratory studies noting the phenomenological evidence for this innovative therapy, limited mechanistic insights have prevented rigorous and reproducible PBM clinical protocols. This article briefly reviews current evidence and focuses on gaps in knowledge to identify potential paths forward for clinical translation with PBM therapy with an emphasis on craniofacial wound healing. PBM offers a novel opportunity to examine fundamental nonvisual photobiological processes as well as develop innovative clinical therapies, thereby presenting an opportunity for a paradigm shift from conventional restorative/prosthetic approaches to regenerative modalities in clinical dentistry.
所有生物体生存的基本病理生理反应是伤口愈合过程。愈合不足或缺乏构成了许多口腔和全身性疾病的病因病理基础。在众多促进伤口愈合的努力中,生物光子学疗法已显示出很大的前景。光子技术的进步以及对光与组织相互作用的更好理解,源于诸如体内光学成像和光遗传学等平行生物光子学领域,正推动其在生物学和医学中的普及。高剂量激光和光设备在皮肤科、眼科、肿瘤学和牙科中的应用现在在特定临床应用中很受欢迎,如手术、皮肤年轻化、眼部和软组织重塑以及抗肿瘤和抗菌光动力疗法。然而,一种不太为人所知的临床应用是低剂量生物光子学的治疗用途,称为光生物调节(PBM)疗法,其旨在减轻疼痛和炎症、调节免疫反应以及促进伤口愈合和组织再生。尽管临床和实验室研究中有大量科学文献记录了这种创新疗法的现象学证据,但有限的机制见解阻碍了严格且可重复的PBM临床方案。本文简要回顾了当前证据,并聚焦于知识空白,以确定PBM疗法临床转化的潜在前进道路,重点是颅面部伤口愈合。PBM提供了一个新机会来研究基本的非视觉光生物学过程以及开发创新临床疗法,从而为临床牙科从传统修复/假体方法向再生模式的范式转变提供了机会。
