Impact of root canal treatment timing on the prognosis of autotransplanted teeth with complete root formation: a systematic review and meta-analysis.
Synthesis in BMC oral health, 2026. 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
objectiveThis systematic review evaluated the influence of root canal treatment (RCT) timing on the prognosis of autotransplanted teeth with complete root formation. MATERIALS AND
methodsA systematic review was conducted according to the PRISMA guidelines. This study estimated survival rate, success rate, and root resorption rate of the teeth overall and across three RCT timings: postoperative prophylactic, intraoperative immediate, and clinical observation-based. Subgroup analyses were performed to investigate the influence of tooth type on outcomes.
resultsA total of 24 studies were included, involving 1473 autotransplanted teeth. The overall survival rate was 95% (95% confidence interval [CI]: 91%–97%), the success rate was 92% (95% CI: 80%–97%), and the root resorption rate was 16% (95% CI: 8%–30%). No statistically significant differences were observed in the survival rate and success rate among the postoperative prophylactic RCT group, intraoperative immediate RCT group, and clinical observation-based RCT group (all P > 0.05). However, the postoperative prophylactic RCT group exhibited the lowest root resorption rate (11%, 95% CI: 6%–18%).
conclusionsCurrent evidence indicates that different timings of RCT exert no significant impact on the overall prognosis of autotransplanted teeth with complete root formation. Nevertheless, postoperative prophylactic RCT may confer potential advantages in reducing the risk of root resorption. Due to the limitations of the non-randomized study design and heterogeneity of the included literature, this conclusion warrants verification by more high-quality studies. CLINICAL IMPLICATIONS: By systematically clarifying the prognostic differences and temporal evolution patterns associated with different RCT timings, this study provides exploratory observations and reference directions for the field of mature tooth autotransplantation, which is conducive to promoting the standardized application of this technique.
