钙质沉积可以发生在全身,也可以发生局部器官组织,发生在牙髓中的钙质沉积称为牙髓钙化。人类牙髓中的钙化结构相当常见,可以发生在任何一个乳牙、恒牙、甚至未萌出的或阻生的牙齿中。然而究竟应该把牙髓钙化看作是生理性的还是病理性的,至今仍有争论,本文复习牙髓钙化的发生率、病因、病理及其临床意义。 1 牙髓钙化的发生率 Calcium deposition can occur in the body, but also can occur in local organ tissue, calcification occurs in the dental pulp is called dental pulp calcification. The calcified structure in human pulp is fairly common and can occur in any of the deciduous teeth, permanent teeth, or even non-adherent or impacted teeth. However, whether dental pulp calcification should be regarded as physiological or pathological remains controversial. This article reviews the incidence of dental pulp calcification, its etiology, pathology and clinical significance. 1 dental pulp calcification incidence
