Piezosurgery versus conventional osteotomy: a randomized clinical trial on pain and anxiety in children with unerupted mandibular third molars.
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, 1 of them a synthesis that pooled it.
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
objectiveDental anxiety for unerupted mandibular third molars extraction in children under local anesthesia is a tricky problem. The purpose of this study was to compare psychological and physiologic findings of extractions of unerupted mandibular third molars in children by piezosurgery and conventional osteotomy. MATERIALS AND
methodsThis prospective, single-center, double-blind study included children who required extraction of mandibular third molars under local anesthesia. All subjects were randomly divided into two groups: piezosurgery and conventional osteotomy (control). The primary outcome variables were dental anxiety assessed by the Modified Child Fear Survey Schedule Dental Subscale (CFSS-DS) and postoperative pain qualified by the visual analog scale (VAS). Secondary outcome variables included blood pressure, heart rate, saturation, and operation duration. The data were analyzed by t-test and chi-square test (P ≤ 0.05).
resultsAll 40 study patients (37.5% males and 62.5% females with an average age of 14.43 ± 1.32 years) completed the entire trial. There were no statistically significant differences observed between the two groups in terms of gender allocation, age, side of extraction, and Winter's Classification (P > 0.05). The operation duration of the piezosurgery group was significantly longer than the conventional osteotomy group (P < 0.01). The VAS scores showed that pain levels of children in the piezosurgery group were significantly less than the conventional osteotomy group on the first and third days postoperatively (P < 0.05 and P < 0.01, respectively). The CFSS-DS score in the piezosurgery group significantly decreased compared to the conventional osteotomy group (P < 0.05). Compared with the conventional osteotomy group, a significant decrease in heart rate, and lower systolic and diastolic blood pressures were observed after extraction in the piezosurgery group (P < 0.05 and P < 0.01, respectively).
conclusionCompared with conventional osteotomy, piezosurgery can effectively reduce postoperative pain and have some effect in relieving dental anxiety for the extraction of unerupted mandibular third molars in children. CLINICAL RELEVANCE: Piezosurgery may be a viable technique for the extraction of unerupted mandibular third molars in children under local anesthesia.
