BACKGROUND/AIMS: Avulsion of a permanent tooth is one of the most severe traumatic dental injuries, comprising an estimated 0.5%-16% of all dental injuries. The aim of this study was to estimate the direct financial costs of tooth avulsion in children based on stage of root maturity and the occurrence of ankylosis and to report patients' characteristics and outcomes of treatment.
A retrospective review of the dental records of children ages 6-18 who sustained a permanent tooth avulsion from 2010 to 2020 was completed. Relative Value Units (RVUs) were used to calculate the estimated cost of dental trauma care over the 2-year post-injury period for five different scenarios of avulsed teeth based on the stage of root maturity, the occurrence of ankylosis and whether the tooth was replanted.
There were 452 avulsed permanent teeth in 348 patients. Of those, 157 teeth were included in the cost analysis. Overall, the average direct dental cost of avulsion was 46.4 RVUs equal to $1619 USD based on the 2021 conversion rate ($34.89 per RVU). Direct costs ranged between 40 RVUs ($1396) and 52.8 RVUs ($1842) depending on the root maturation and ankylosis status or whether the tooth was replanted; however, ANOVA test did not show any statistically significant differences between the mean RVUs of different groups (p = .85). Patients returned 9.5 times on average over the 2-year study period for dental trauma care after avulsion.
The average direct cost of tooth avulsion within the limits of this study was $1619 USD. On average, patients returned for 9.5 follow-up visits after the avulsion. The stage of root maturity, the occurrence of ankylosis and whether the tooth was replanted or not were not significantly associated with the direct cost of dental care.
背景/目的：恒牙脱位是最严重的外伤性牙损伤之一，约占所有牙损伤的0.5%-16%。本研究的目的是根据牙根成熟阶段、有无牙根粘连情况估计儿童牙脱位的直接经济成本，并报告患者特征及治疗结果。
对2010年至2020年期间发生恒牙脱位的6至18岁儿童的牙科记录进行回顾性研究。基于牙根成熟阶段、有无牙根粘连情况以及牙齿是否再植，使用相对价值单位（RVU）计算5种不同牙脱位情况在伤后2年期间的牙外伤治疗估计成本。
348例患者中有452颗恒牙脱位。其中，157颗牙齿纳入成本分析。总体而言，根据2021年换算率（每RVU 34.89美元），脱位的平均直接牙科成本为46.4 RVU，相当于1619美元。根据牙根成熟度、牙根粘连状况或牙齿是否再植，直接成本在40 RVU（1396美元）至52.8 RVU（1842美元）之间；然而，方差分析未显示不同组平均RVU之间存在任何统计学显著差异（p = 0.85）。在2年研究期间，患者脱位后平均因牙外伤治疗复诊9.5次。
在本研究范围内，牙脱位的平均直接成本为1619美元。平均而言，患者脱位后进行了9.5次随访。牙根成熟阶段、有无牙根粘连情况以及牙齿是否再植与牙科护理的直接成本无显著关联。
