This study aimed to determine the incidence and contributing factors to pulpal and periapical disease in crowned vital teeth. Seventy-three pairs of healthy teeth were included and divided into two groups; 'crowned' and 'untreated' groups. The crowned group was prepared for full coverage crown and no treatment was carried out on the untreated group. Both groups were subjected to clinical and radiographic examination to detect endodontic signs and symptoms pre-operatively and one-week after crown cementation. Electric pulp test was also subjected to both groups, pre-operatively, after tooth preparation and before crown cementation. The incidence of pulpal and periapical disease was 6.8% and 1.4%, respectively, after tooth preparation. Factors associated with pulpal and periapical disease were exposed pulp during tooth preparation and pre-operative bone level <35%. Despite the low incidence, the occurrence of pulpal and periapical disease within a short period is noteworthy.
本研究旨在确定带冠活髓牙牙髓和根尖周疾病的发病率及相关因素。纳入了73对健康牙齿，并将其分为两组；“带冠组”和“未治疗组”。带冠组准备进行全冠修复，未治疗组不进行任何治疗。两组均在术前和冠修复粘结后一周接受临床和影像学检查，以检测牙髓病体征和症状。两组在术前、牙体预备后和冠修复粘结前均进行了牙髓电活力测试。牙体预备后，牙髓和根尖周疾病的发病率分别为6.8%和1.4%。与牙髓和根尖周疾病相关的因素包括牙体预备时露髓和术前骨水平<35%。尽管发病率较低，但短期内牙髓和根尖周疾病的发生仍值得关注。
