Assessment of fractal dimension changes in periapical trabecular patterns following single-visit and multi-visit nonsurgical endodontic treatment with different medicaments: a retrospective study.

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
objectiveThis study aimed to compare time-dependent changes in fractal dimension (FD) and periapical index (PAI) values of periapical trabecular bone in the lesion areas following single- and multi-visit end-odontic treatments using different intracanal medicaments. MATERIAL AND
methodsData from 62 mandibular molars treated between March and December 2023 were analyzed and assigned to three groups: Group 1, multi-visit treatment with calcium hydroxide [Ca(OH)₂] (n = 20); Group 2, multi-visit treatment with chlorhexidine (CHX) gel (n = 21); and Group 3, single-visit treat-ment without medicament (n = 21). Follow-up data were collected until December 2024. Three periapical radiographs, baseline, 6-months, and 12 months after treatment, were evaluated. Fractal analysis was per-formed on a region of interest (ROI) near the infected root apex, and periapical healing was also assessed using PAI scores. PAI scores were compared using the Kruskal-Wallis test; FD values and their correlation with PAI were analyzed by two-way analysis of variance (ANOVA) and Spearman's test. Categorical variables were compared using the chi-square and Fisher-Freeman-Halton tests.
resultsPAI scores significantly decreased in all groups at 6 and 12 months compared with baseline (p < 0.001), with no intergroup differences (p > 0.05). FD values significantly increased over time in all groups (p < 0.001). The magnitude of FD change and gender-related differences were not significant (p > 0.05). No correlation was observed between PAI and FD values (p > 0.05).
conclusionsSingle- and multi-visit endodontic treatments resulted in similar periapical healing out-comes. The type of intracanal medicament did not influence FD or PAI values. Fractal analysis is a valuable, noninvasive tool for assessing periapical bone healing over time.
