From early prevention to invasive treatment: dental care utilization and outcomes according to gestational age in preterm children.
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. 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
backgroundPreterm birth is associated with long-term developmental vulnerability, including altered dental development and oral health. Although preterm children tend to visit dental clinics earlier and receive preventive care more frequently than full-term peers, it remains unclear whether such preventive-oriented utilization reduces the need for invasive dental treatment. This study aimed to evaluate dental care utilization patterns and clinical outcomes according to gestational age in preterm children.
methodsThis retrospective observational study analyzed electronic medical records of children who attended a tertiary pediatric dental clinic between January 2020 and December 2024. Participants were classified into four groups based on gestational age: extremely preterm (< 28 weeks), very preterm (28-31 weeks), late preterm (32-36 weeks), and full-term (≥ 37 weeks). Demographic characteristics, age at first dental visit, reasons for visits, preventive and therapeutic dental procedures, sedation and general anesthesia, and early extraction of primary molars were assessed. Group differences were evaluated using chi-square tests and one-way analysis of variance. Multivariable logistic regression analyses were performed to estimate adjusted odds ratios for dental outcomes according to gestational age, controlling for sex, age at first dental visit, and residential area.
resultsA total of 7,352 children were included in the analysis. Preterm children, particularly those born extremely preterm, visited dental clinics at a younger age and received preventive interventions, such as fluoride application, more frequently than full-term children (p < 0.001). Despite higher preventive care utilization, extremely preterm children showed higher frequencies of invasive treatments, including tooth extraction and inpatient general anesthesia. Tooth developmental anomalies were significantly more prevalent in all preterm groups, with the highest risk observed in extremely preterm children (adjusted odds ratio 3.43, 95% confidence interval 2.23-5.26). Early extraction was selectively concentrated in the second primary molars among extremely preterm children.
conclusionsPreterm children, especially those born extremely preterm, demonstrate a distinct dental care trajectory characterized by early preventive utilization but an increased likelihood of invasive treatment once intervention becomes necessary. These findings highlight the importance of risk-stratified surveillance and tailored preventive strategies, with particular attention to developmentally vulnerable teeth, to optimize long-term oral health outcomes in preterm populations.
