Separation effect, pain perception during functional activity and gingival inflammation of elastomeric and Kansal separators-a split mouth study.
Trial report in Clinical oral investigations, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionAn effective space opening for band placement with minimal pain and gingival inflammation is a prime requisite during fixed orthodontic procedures. The study aimed to compare the effectiveness of two types of separators, elastomeric and Kansal, in the amount of space opening, pain perception elicited, and gingival inflammation.
methodsA random split-mouth study was designed with 30 subjects undergoing fixed orthodontic treatment. Two different separators (Elastomer and Kansal) were placed alternatively on the left and right sides around the mesial and distal sides of the first molars in the mandibular arch of each subject. After 3 days, the amount of separation after 3 days was assessed with a leaf gauge on both mesial and distal sides. The subjective pain perception by visual analog Scale (VAS) at different points and during different functions for each of the 3 days was evaluated. A self-filled chart was utilized to be performed by the patients. Gingival index was used to assess the inflammatory changes.
resultsThe most significant amount of separation (0.28 mm) was found with elastomers on the mesial side and is statistically significant (p < 0.001) compared to the mesial side (0.18 mm). The Kansal separators produced equivalent separation on mesial (0.19 mm) and distal sites (0.17 mm). The highest pain score was found after 24 h with elastomeric separators (median-40) for chewing and biting and the least for sleep (median-30). There is a statistical difference of pain perception between elastomers and Kansal separators at different points for the given function (p < 0.001). Both the separators resulted in mild gingival index of score less than 1 (0.70 ± 0.65, 0.97 ± 0.720, and there was no statistically significant difference between the two types of separators.
conclusionBoth the separators produced adequate separation after a minimum 3 days. Kansal produces minimum discomfort and pain compared to elastomeric separators. Mild gingival inflammation was observed with both the separators.
