Pulp calcification is one of important factors that make root canal preparation difficult. The pathogency is not clear. Many factors could promote its progression, including age, trauma and microorganisms and so on. Diagnosis methods usually include X-ray radiography, cone beam computer tomography, observation under an operative microscope and histologic sections. Applying an operative microscope and ultrasonic together in dealing with calcified canals during root canal treatment could raise the success rate. This paper reviews the causes, influence factors, diagnosis and treatment methods of pulp calcification.%牙髓钙化是导致根管预备困难的重要原因之一.病因尚不清楚,主要有年龄、外伤和微生物等因素.诊断牙髓钙化的主要手段有X线片、锥形束CT、显微镜观察以及组织切片等方法,临床上将手术显微镜和超声技术结合处理牙髓钙化的根管,可以提高根管治疗的成功率.本文对牙髓钙化的病因、影响因素、诊断方法和处理措施等研究进展进行综述.
