1 · What the graph read from it

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.

2 · The registry

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

purposeThis study aimed to evaluate the success rate of pulpectomy in primary teeth under dental general anaesthesia (DGA), identify factors associated with outcomes in teeth with periapical disease, and investigate the characteristics and factors associated with hollow-tube formation.

methodsWe, retrospectively, analysed children undergoing primary tooth pulpectomy under DGA between December 2019 and November 2022. Demographic data, preoperative dental status, operative parameters, and follow-up outcomes were collected. Tooth survival was assessed with life-table analysis, and associated factors were analysed using multivariate Cox regression, with failure times for interval-censored data approximated at midpoints. Logistic regression was used to evaluate factors associated with root filling material resorption.

resultsAmongst 528 treated primary teeth from 171 patients (mean age 4.66 years), median survival time fell within ranges of 36 to 42 months clinically and 30 to 36 months radiographically. Multivariable regression identified age, tooth type, endodontic diagnosis, and obturation quality as significant indicators of failure (p < 0.05). In teeth with apical lesions, preoperative root resorption was significantly associated with failure (p = 0.028). Radiographically, 469 teeth showed resorption of filling material. Of 145 teeth exhibiting the hollow tubes, 33 progressed to radiographic failure. Younger age, pulpitis, and overfilling were the factors associated with hollow-tube formation.

conclusionThe survival rate of primary teeth after pulpectomy under DGA declined rapidly over time. In teeth with apical lesions, preoperative root resorption was a major factor affecting survival. While teeth showing hollow tubes may demonstrate short-term stability, the long-term prognosis remains uncertain.
