Clinical outcomes and parental satisfaction of two stainless steel crown systems in pediatric patients: a retrospective observational cohort study.
Observational study in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07393854 (Clinical Success and Parental Satisfaction of Two Commercially Available Stainless Steel Crowns in Pediatric Patients Under General Anesthesia), which is not on this map.

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.

Abstract
backgroundStainless steel crowns (SSCs) are widely used for restoring severely carious primary molars. However, clinical evidence comparing different commercially available SSC systems remains limited. This study aimed to compare the clinical success and parental satisfaction of two SSC systems, Kids Crown and NuSmile, in pediatric patients.
methodsThis retrospective observational cohort study included children aged 2-8 years who received at least one SSC under general anesthesia and had a minimum follow-up of 6 months. Clinical evaluations were performed by a single calibrated examiner and assessed crown retention, marginal adaptation, occlusion, proximal contact, gingival health, oral hygiene status, and biological or mechanical complications. Parental satisfaction was evaluated using a 5-point Likert-scale questionnaire. Non-parametric statistical tests were applied with a significance level set at p < 0.05; all tests were two-sided.
resultsA total of 65 children (246 crowns) were included, with a mean follow-up of 20.12 ± 13.31 months. Both SSC systems demonstrated high clinical success, with overall crown retention exceeding 97%. Good marginal adaptation was observed in 98.3% of crowns and was significantly more frequent in the Kids Crown group than in the NuSmile group (p = 0.038). No significant intergroup differences were found for retention, occlusion, proximal contact, gingival index, or oral hygiene status. Parental satisfaction scores were high in both groups, particularly regarding durability and overall satisfaction.
conclusionsBoth Kids Crown and NuSmile SSC systems showed high clinical success and parental acceptance in pediatric patients treated under general anesthesia. Although marginal adaptation favored Kids Crown, the overall clinical relevance of this difference appears limited.
