Anti-Aging Protein Klotho Shows Promise Against Oral and Dental Diseases

Klotho, widely recognized for its anti-aging properties in systemic diseases, is emerging as a key protective factor in oral and maxillofacial health. This comprehensive review highlights the growing evidence for Klotho's clinical significance in dental and oral medicine.

The protein exerts its protective effects through multiple molecular signaling pathways, including Nrf2, NF-κB, PI3K/Akt/FoxO1, insulin/IGF-1, FGF/FGFR, and Wnt/β-catenin. Through these pathways, Klotho regulates four critical cellular processes: oxidative stress, programmed cell death (apoptosis), inflammation, and tissue scarring (fibrosis).

Research demonstrates Klotho's protective role across various oral conditions including periodontitis (gum disease), oral squamous cell carcinoma, malignant salivary gland tumors, and oral submucous fibrosis. A consistent pattern emerges showing that decreased Klotho expression or impaired function correlates with disease onset and progression.

These findings suggest Klotho could serve dual roles as both a biomarker for early disease detection and a therapeutic target for treatment. The protein's involvement in fundamental aging processes may explain why oral health often deteriorates with age, offering new insights into age-related dental problems.

This research opens promising avenues for developing Klotho-based interventions in oral medicine, potentially revolutionizing how we prevent and treat dental diseases through targeting aging mechanisms at the cellular level.
