Information regarding the prevalence of pulp calcifications in primary teeth is lacking. The occurrence of pulp calcifications in 120 primary maxillary and mandibular extracted teeth was evaluated radiographically. Twenty-five percent of second molars presented evidence of pulp calcifications; approximately 3% of central incisors were calcified. No other categories of teeth displayed pulp involvement. The low occurrence of pulp calcifications in primary teeth support the view that the occurrence of pulp calcification increases with age.
关于乳牙牙髓钙化患病率的信息尚缺。通过影像学评估了120颗上颌和下颌拔除乳牙中牙髓钙化的发生率。25%的第二磨牙有牙髓钙化迹象；约3%的中切牙发生钙化。其他类别的牙齿未显示牙髓受累情况。乳牙牙髓钙化发生率较低，这支持了牙髓钙化发生率随年龄增长而增加的观点。
