Non-surgical endodontic retreatments in Brazil's public dental services: a 15-year nationwide register-based study.
Article in Brazilian dental journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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.
