Bioelectricity phenomenon is the basic property of life activity. Biological electric fields have an important function in physiological processes, such as biological morphogenesis and growth. Biological electric fields participate in important pathological processes, such as wound healing and tissue regeneration. Periodontitis is a chronic infectious disease of the periodontal support tissues and is caused by plaque microbes. Moreover, periodontitis is the major cause of tooth loss in adults. Research has shown that electrical stimulation has antibacterial effects and is capable of promoting tissue healing and bone formation.This article aims to review the research progress of the electrical stimulation in periodontology.
