Comparative evaluation of changes in levels of cytokine - IL-1β in GCF of adult population who have undergone piezocision and corticotomy assisted orthodontics- an in vivo study.
Trial report in BMC oral health, 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
backgroundAccelerating orthodontic treatment is crucial in reducing complications such as root resorption, caries, and oral hygiene compromise, especially in adults. Piezocision and corticotomy are surgical techniques that accelerate tooth movement by causing bone remodelling. This study compares and evaluates changes in Interleukin-1β (IL-1β) levels in gingival crevicular fluid (GCF) following piezocision and corticotomy-facilitated orthodontics in adults.
aimTo assess and compare IL-1β fluctuations in GCF of adult patients undergoing corticotomy and piezocision-assisted orthodontic treatment. MATERIALS &
methodsThis split-mouth study consisted of 16 adult patients (18-25 years) who needed premolar extractions. One half of the maxilla was randomly assigned for piezocision and the other half for corticotomy. GCF samples were taken from maxillary canines at varying time intervals: pre-treatment (T0), before surgery (T1), and 24 h (T2), 7 days (T3), and 21 days (T4) following surgery. IL-1β concentrations were quantified using an ELISA kit, and statistical analysis was done.
resultsIL-1β concentrations were highest at 24 h after surgery (T2) in both groups and decreased steadily by day 21 (T4), but were still elevated above pre-treatment levels. IL-1β concentrations were significantly greater in the piezocision group at all time points after surgery than in the corticotomy group (p < 0.001), reflecting a more intense inflammatory reaction and greater bone cell metabolism.
conclusionThis study suggests that piezocision elicits a more intense biological response than corticotomy, as reflected by higher IL-1β levels in gingival crevicular fluid. While this may indicate a potential for enhanced bone remodelling and accelerated tooth movement, further research is needed to directly correlate cytokine expression with the rate of orthodontic tooth movement.
