Abstract:
Photobiomodulation (PBM), formerly known as low-level laser therapy (LLLT), utilizes red and near-infrared light to activate mitochondrial chromophores, thereby enhancing cellular activity, modulating inflammation and promoting tissue repair. Therefore, it is of interest to the mechanistic pathways of PBM, including mitochondrial stimulation, cytokine regulation and growth factor induction. Clinical evidence supports its efficacy in managing oral mucositis, temporomandibular disorders, periodontitis, postoperative endodontic pain, implant stability and orthodontic treatment outcomes.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
