pulpitis, pulp necrosis, increased mobility of tooth, and even tooth loss. Besides, people might suffer from acute symptoms, such as swelling, pain,
pus discharge or cellulitis. In recent years, association between oral diseases and systemic health has been frequently reported in the literature. Good oral hygiene care is of paramount importance in preventing the occurrence of oral diseases.
Regular examination and follow-up are suggested. Early detection and early treatment can promote oral health and enhance quality of life.
