Developmental Defect of Enamel in Permanent Teeth Associated With Chronic Endodontic Abscess in Deciduous Teeth: A Retrospective Study.
Article in Clinical and experimental dental research, 2025. 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
objectivesDestructive carious lesions on deciduous teeth often result in dental abscesses. Sometimes, the exudative process may extend to the dental follicle of the permanent tooth, leading to various types of consequences. This study primarily seeks to determine the prevalence of developmental defects of enamel (DDE) in premolars whose predecessors developed endodontic abscesses. Furthermore, it investigates how the prevalence of DDE is influenced by the type of treatment the affected deciduous molar received. Lastly, the study compares the prevalence of DDE between maxillary and mandibular premolars. MATERIAL AND
methodsDemographics, medical and dental history, and records of DDE were extracted from the medical records of 1164 pediatric patients. DDE of 107 premolars from patients who had experienced abscesses in their deciduous molars were compared to DDE of 107 premolars from patients who naturally shed healthy deciduous molars. DDE were also compared between different treatment modalities and anatomical regions. Fisher's exact tests were used to compare groups, while demographic data were analyzed by descriptive statistics and reported as mean ± standard deviation or as median and interquartile range for the continuous variables.
resultsCompared to premolars whose predecessors did not exhibit signs of pathology, those that developed endodontic abscesses reported a higher prevalence of DDE (57% vs. 17.8%; OR 6.14; p < 0.0001). Endodontic treatment on deciduous molars was associated with higher DDE prevalence compared to surgical treatment (70.2% vs. 46.7%; OR 2.69; p = 0.016). Maxillary premolars showed a higher prevalence of DDE compared to mandibular premolars (75.4% vs. 24.6%; OR 5.23; p = 0.00008).
conclusionsChronic endodontic abscess on deciduous molars significantly increases the risk of DDE in the corresponding premolars. ET on deciduous molars is associated with higher incidence of DDE compared to extraction. Maxillary premolars are more likely to develop DDE than mandibular premolars.
