Does piezocision induce root resorption or periodontal problems in class II patients?: A 2-year follow-up study.
Article in Journal of orthodontic science, 2026. 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
objectiveThis study aimed to evaluate the potential for root resorption and periodontal complications in patients with Class II malocclusion undergoing piezocision-assisted orthodontic treatment over a 2-year follow-up period. MATERIALS AND
methodsTwenty patients (11 females, 9 males; mean age: 16.1 ± 2.8 years) requiring bilateral canine distalization and maxillary first premolar extraction were included in this split-mouth study. One quadrant was randomly assigned to undergo piezocision, while the contralateral quadrant served as the control. Panoramic radiographs were utilized to assess root resorption at baseline (T1), and 2 years post-treatment (T2). Additionally, gingival health and tooth mobility scores were evaluated. Statistical analyses were performed using the Wilcoxon signed-rank test.
resultsNo clinically significant root resorption was observed in either group. Mild resorption was noted on the upper canine of one patient in the piezocision group, while another patient in the control group exhibited resorption on the upper lateral incisor. Gingival health, and mobility scores decreased from T1 to T2 in both groups, with no statistically significant differences found between the piezocision and control sides. Scar formation on the attached gingiva was observed in one patient following piezocision; however, this was not associated with bone loss or increased periodontal pocket depth.
conclusionPiezocision-assisted orthodontic treatment did not result in clinically significant root resorption or adverse periodontal outcomes in patients with Class II malocclusion over a 2-year period. These findings support the safety of piezocision as a method for accelerating tooth movement without compromising periodontal health. Further research with larger sample sizes and histological assessments is recommended to validate these results.
