This study aimed to investigate the predictors of survival of non-occlusal non-incisal glass-ionomer restorations as a surrogate for root surface restorations among older adults.
In a retrospective cohort analysis using the University of Iowa College of Dentistry electronic dental records, we included 721 patients aged 65+ who received 2+ surface non-occlusal non-incisal glass ionomer restorations placed from January 2005 - December 2011. Restorations were followed until September 2017 or until they were deemed to have failed.
At baseline, participants' mean age was 77.6 ± 8.2 years, and 45.8% were females. Most patients were self-pay (65.2%). Most restorations were placed by residents and dental students (82.7%) and included only two surfaces (95.6%). About half (49.1%) failed during follow-up, with a median survival time of 3.7 years. The time ratio for lower incisors compared to other teeth was 0.6 (p = .006), for three-and-four-surface restorations compared to two was 0.7 (p = .007), for faculty as providers compared to residents and students was 1.4 (p = .039), and for the Geriatric & Special Needs Clinic compared to others was 0.8 (p = .013). Time ratios less than one indicate association with shorter durations for restorations, and time ratios greater than one indicate association with longer durations for restorations.
Tooth type, number of restored surfaces, provider type, and clinic were all significant factors associated with survival of these restorations.
本研究旨在探讨非咬合非切缘玻璃离子水门汀修复体的生存预测因子，作为老年患者根面修复体的替代物。
在一项使用爱荷华大学牙科学院电子牙科记录的回顾性队列分析中，我们纳入了 721 名年龄在 65 岁及以上的患者，他们在 2005 年 1 月至 2011 年 12 月期间接受了 2 次及以上的非咬合非切缘表面玻璃离子水门汀修复。修复体随访至 2017 年 9 月或直至修复失败。
基线时，参与者的平均年龄为 77.6±8.2 岁，45.8%为女性。大多数患者为自费（65.2%）。大多数修复体由住院医师和牙科学生（82.7%）放置，仅包括两个表面（95.6%）。约一半（49.1%）在随访期间失败，中位生存时间为 3.7 年。下前牙与其他牙齿的时间比为 0.6（p=0.006），三、四表面修复体与两表面修复体的时间比为 0.7（p=0.007），教师作为提供者与住院医师和学生的时间比为 1.4（p=0.039），老年和特殊需求诊所与其他诊所的时间比为 0.8（p=0.013）。时间比值小于 1 表明与修复体持续时间较短相关，而时间比值大于 1 表明与修复体持续时间较长相关。
牙齿类型、修复表面数量、提供者类型和诊所都是与这些修复体生存相关的重要因素。
