A Retrospective Study of Replacement Resorption and Its Risk Factors After Replantation of Avulsed Young Permanent Teeth.
Article in Clinical and experimental dental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveA retrospective study was conducted on 30 cases of replacement resorption after replantation of avulsed young permanent teeth with clinical observation period of more than 2 years, to provide reference for clinical treatment and prevention.
methodsA retrospective study was carried out on 30 cases replacement resorption after replantation of avulsed young permanent teeth with replacement resorption. The clinical and imaging data during posttraumatic follow-up were recorded and analyzed, including trauma age, gender, traumatic tooth position, root development stage, time of tooth separation, storage media, fixed time, and clinical examination.
resultsAmong the 30 cases, the fastest replacement resorption occurred in the first month after trauma (1 case), and the slowest occurred in the 24th month (1 case). The incidence of replacement resorption was 26.7% at month 3, 70% at month 6, 90% at month 9, and 96.7% at month 12. Fifteen patients showed progressive ankylosis, the degree of ankylosis gradually increased. Analysis and screening of risk factors found that the extraoral time was statistically significant.
conclusionThe study shows that the longer the time in vitro, the more likely progressive tooth sinking will occur, resulting in tooth loss. Therefore, it is more important to popularize the emergency treatment of mean avulsion. How to correctly deal with prolapse teeth, how to optimize the emergency trauma channel, reduce the occurrence of delayed replantation, and prolong the life of replantation teeth will be the focus of the future work of pediatric stomatologists.
