This study examined the prevalence of endodontic treatment in a group of 184 Dutch adults, and determined the periapical status of all teeth using panoramic radiographs. The results indicate that in this group, 2.3% of the teeth were root-filled, and that 5.2% of all non-endodontically treated teeth showed signs of periapical pathology. Around the apices of 39.2% of the endodontically treated teeth in this survey, radiographic signs of periapical pathology were observed. Using the level of the root canal filling as a criterion for evaluating the quality of the root canal treatment, 50.6% of the endodontic treatments were qualified as inadequate. There was a significant correlation between the presence of periapical pathology and underfilling of the root canal(s). 44.6% of the patient sample had at least one tooth with radiographic signs of periapical pathology, indicating a substantial future need for endodontic treatment.
本研究调查了184名荷兰成年人的牙髓治疗患病率，并使用全景X线片确定了所有牙齿的根尖周状况。结果表明，在该组中，2.3%的牙齿进行了根管充填，所有未经牙髓治疗的牙齿中有5.2%显示出根尖周病变的迹象。在本次调查中，39.2%接受牙髓治疗的牙齿根尖周围观察到根尖周病变的影像学征象。以根管充填水平作为评估根管治疗质量的标准，50.6%的牙髓治疗被判定为不合格。根尖周病变的存在与根管欠填之间存在显著相关性。44.6%的患者样本中至少有一颗牙齿有根尖周病变的影像学征象，表明未来对牙髓治疗有大量需求。
