The objective of this study was to analyze the provision of non-surgical endodontic retreatments in Brazil's public dental services from 2008 to 2022. A time series was outlined for this purpose. The annual numbers of non-surgical endodontic retreatments were retrieved from the Brazilian National Outpatient Information System and adjusted per 100,000 inhabitants to obtain the incidence between 2008 and 2022. Comparison of the incidence between types of teeth, temporal trend estimation, and evaluation of the COVID-19 pandemic-related impacts were conducted with a significance level of 5%. In this timeframe, 1,270,182 non-surgical endodontic retreatments were carried out. A higher incidence was observed among single-rooted teeth (328/100,000) when compared to double-rooted (183/100,000) and multi-rooted teeth (112/100,000) (p <0.05). The annual incidences showed a significantly decreasing trend over the last 15 years for all types of teeth (p <0.05), as well as demonstrated a highly correlated pattern of temporal variation (p <0.05). In addition, there was no influence on this outcome when removing the period between 2020 and 2022 (all temporal trends remained decreasing). However, the monthly incidence was significantly lower in the first, second, and third years after the COVID-19 pandemic onset (p <0.05). The provision of non-surgical endodontic retreatments in Brazil's public dental services has experienced a dramatic decline over the past 15 years, including after the COVID-19 pandemic.
本研究的目的是分析2008年至2022年巴西公共牙科服务中进行的非手术性根管再治疗情况。为此制定了一个时间序列。从巴西国家门诊信息系统中检索每年非手术性根管再治疗的数量，并按每10万居民进行调整，以得出2008年至2022年期间的发病率。对不同类型牙齿的发病率进行比较、估计时间趋势以及评估与新冠疫情相关的影响，显著性水平设定为5%。在此时间范围内，共进行了1,270,182次非手术性根管再治疗。与双根牙（183/10万）和多根牙（112/10万）相比，单根牙的发病率更高（328/10万）（p<0.05）。在过去15年中，所有类型牙齿的年发病率均呈现出显著下降趋势（p<0.05），并且显示出高度相关的时间变化模式（p<0.05）。此外，去除2020年至2022年期间的数据对这一结果没有影响（所有时间趋势仍呈下降趋势）。然而，在新冠疫情爆发后的头三年，每月发病率显著较低（p<0.05）。在过去15年中，包括新冠疫情之后，巴西公共牙科服务中非手术性根管再治疗的提供情况经历了急剧下降。
