Prevalence and distribution of dental anomalies in permanent teeth among children and adolescents attending the University Dental Hospital in Sivas, Türkiye: a radiographic cross-sectional study.
Article 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
backgroundDental anomalies (DA) in pediatric patients can have wide-ranging implications, including impaired aesthetics, compromised oral function and adverse effects on psychological well-being. This study aimed to evaluate the prevalence and distribution of DA according to gender and jaw in permanent teeth of children and adolescents attending the University Dental Hospital in Sivas, Türkiye and to compare the findings with reports from other regions of Türkiye and worldwide populations.
methodsThis cross-sectional study evaluated digital panoramic radiographs and clinical records of 1030 patients aged 8 to 15 years who attended for routine treatment at Sivas Cumhuriyet University Dental Hospital between January 1, 2021, and December 31, 2023. A calibrated examiner conducted the evaluation to identify dental anomalies, which were categorized into four subgroups: number, size, shape and position anomalies. The significance of associations between categorical variables was assessed using the Chi-square test and Fisher's Exact test, with significance set at p < 0.05.
resultsOf the patients included in the study, 53.6% were female and 46.4% were male. The prevalence of dental anomalies was 20.7% and the mean age of children with dental anomalies was 10.88 ± 2.32 years. The most prevalent dental anomaly was tooth agenesis (9.7%), followed by ectopic eruption (3.3%), root dilaceration (2.8%), impacted teeth (1.8%) and taurodontism (1.2%) respectively. Taurodontism was significantly more prevalent in males than in females (p = 0.043). A significantly higher number of dental anomalies were observed in the maxilla compared to the mandible (p = 0.004). Hyperdontia, macrodontia, microdontia, talon cusp and ectopic eruption were significantly more prevalent in the maxilla, while hypodontia was more prevalent in the mandible (p < 0.05).
conclusionsThe prevalence of dental anomalies in permanent teeth among children and adolescents in Sivas was relatively high. The most common dental anomaly was tooth agenesis. The results of this hospital-based study provide baseline information for the region.
