Sleep Restriction Exacerbates Pulpal Inflammation And Impairs Tissue Repair Following Dental Pulp Capping: An In Vivo Animal Study, Siqi Huang, Qian Wang, Ziyu Chen, Guomiao Zhang, Ying Zheng

Journal of Dental Sciences

As a fundamental physiological process, sleep is essential for maintaining systemic homeostasis. Although sleep restriction (SR) has been shown to trigger a systemic inflammatory response, its specific impact on local pulpal inflammation remains poorly understood. In this preliminary study, we investigated the effects of SR on the inflammatory response and reparative capacity of dental pulp in a rat model. Immunohistochemistry and western blotting revealed that, even in intact pulp tissue, SR upregulated the expression of interleukin-6, increased the infiltration of neutrophils, and activated the nuclear factor-kappa B signaling pathway. Subsequent investigations demonstrated that following dental pulp capping, SR provoked an …

The Clinical Applications Of Platelet-Rich Plasma And Platelet-Rich Fibrin Combined With Photobiomodulation In Regenerative Dentistry: A Literature Review, Maryam Pourhajibagher, Rashin Bahrami, Abbas Bahador

Journal of Dental Sciences

Regenerative dentistry seeks to restore oral tissues through biologically driven therapies that stimulate endogenous healing. Among these, autologous platelet concentrates—namely platelet-rich plasma (PRP) and platelet-rich fibrin (PRF)—serve as reservoirs of growth factors such as platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF), which promote angiogenesis, cell proliferation, and extracellular matrix formation. Complementing these biological mediators, photobiomodulation (PBM) represents a non-invasive light-based therapy that enhances mitochondrial activity, modulates inflammation, and accelerates tissue regeneration. Accumulating evidence suggests that combining PRP or PRF with PBM produces synergistic effects that surpass those achieved by …

Herbal Medicine For Oral Ulcer Treatment: Mechanisms, Efficacy, And Therapeutic Potential, Shinn-Zong Lin, Tsung-Hsien Chuang, Chih-Yang Huang, Tsung-Jung Ho, Yi-Pang Lee

Journal of Dental Sciences

Oral ulcers are common inflammatory lesions of the oral mucosa that significantly affect patients’ quality of life through pain, eating difficulties, and psychological stress. Their development is multifactorial, involving mechanical trauma, infection, nutritional deficiencies, immune dysregulation, and oxidative stress. Conventional treatments including antiseptics, corticosteroids, and immunomodulators, provide symptomatic relief but are often limited by side effects, recurrence, and poor patient adherence. Increasing interest has therefore focused on herbal medicines as complementary or alternative therapies. Numerous single herbs such as Aloe vera, licorice, curcumin, chamomile, berberine, neem, sage, myrrh, and guava and traditional formulations have demonstrated anti-inflammatory, antioxidant, immunomodulatory, antimicrobial, and …
