Evidence-based evaluations of dental treatment are needed to support the development of special care dentistry services. This retrospective study was designed to collect and analyse X-ray images of permanent teeth restored with stainless steel crowns (SSC) in patients treated under general anaesthesia. Between 2013 and 2019, 360 permanent molars were crowned with SSCs in 198 adult patients. One calibrated investigator used an original validated tool to evaluate four radiographic criteria for molars restored with SSCs: (i) marginal adaptation; (ii) interdental proximal contact; (iii) the presence of glass ionomer cement overflow; and (iv) the loss of alveolar bone. Overall, no defect or a minor defect was reported for the majority of SSCs for the criteria "Marginal adaptation" (62.5%, = 320), "Proximal contact" (82.2%, = 236) and "Cement overflow" (95.8%, 337). Alveolar bone resorption was reported in 8.3% of cases, = 14, after a mean period of 8.9 ± 14.3 months. It was shown that the restoration of permanent teeth using SSCs placed under general anaesthesia presents a low risk of periodontal morbidity in the medium term when assessed radiographically.
需要进行基于证据的牙科治疗评估，以支持特殊护理牙科服务的发展。本回顾性研究旨在收集和分析在全身麻醉下接受治疗的患者的不锈钢冠（SSC）修复的恒牙的 X 射线图像。在 2013 年至 2019 年期间，198 名成年患者的 360 颗恒牙被 SSC 覆盖。一位经过校准的调查员使用原始验证工具评估了用 SSC 修复的磨牙的四个放射学标准：（i）边缘适应性；（ii）邻面近端接触；（iii）玻璃离子水泥溢出的存在；以及（iv）牙槽骨的丧失。总体而言，对于“边缘适应性”（62.5%，n=320）、“邻面接触”（82.2%，n=236）和“水泥溢出”（95.8%，n=337）这三个标准，大多数 SSC 报告没有缺陷或轻微缺陷。在平均 8.9±14.3 个月后，有 8.3%（n=14）的病例报告了牙槽骨吸收。结果表明，在中期通过放射学评估，使用全身麻醉下放置的 SSC 修复恒牙的风险较低，牙周发病率较低。
