Evaluation of the effect of overhanging restored teeth on alveolar bone by retrospective comparative fractal analysis.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundIt is important to recognize that overhanging restorations can have adverse effects on the alveolar bone. The objective of this study was to evaluate the alterations in the bone surrounding teeth with overhanging restorations on digital panoramic radiographs (DPRs) employing fractal analysis (FA).
methodsA total of 800 DPRs were examined, and 123 teeth presenting with overhanging restorations were identified. The alveolar bone structure around these teeth was analysed along with unrestored areas for comparison. FA was used to evaluate of the DPRs using the box-counting method. The statistical significance level was accepted as p < 0.05.
resultsThe study revealed that fractal dimension (FD) values were significantly lower in areas with overhanging restorations compared to healthy areas (p < 0.001). The analysis revealed that teeth exhibiting signs of overhanging restorations were predominantly located in quadrant 1 (35.8%, n = 44). The analysis revealed that 74.8% of these teeth were molars (n = 92) and 25.2% were premolars (n = 31). The statistical analysis revealed that there was no statistically significant difference in the FD of premolar and molar teeth with overhanging restoration (p > 0.05).
conclusionsThe FD data indicate that overhanging restorations may adversely affect the trabecular structure of the alveolar bone. This finding suggests that careful attention to margin alignment during restorative procedures may be beneficial for the preservation of alveolar bone health.
