Effect of needle bevel type on pain perception in children during inferior alveolar nerve block anesthesia: randomized controlled clinical trial.
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. It is linked to trial NCT07667725 (Effect of External Cooling and Vibration, Counterstimulation, and Needle Type on Pain, Physiological, and Behavioral Outcomes During Inferior Alveolar Nerve Block in Pediatric Patients), which is not on this map. Cited by 2 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.

Abstract
backgroundThe difficulty in providing optimal treatment has been related to patients' fear of the discomfort that comes with anesthetic needle insertion. The main purpose of this study is to clinically assess the effect of needle bevel on patient's perception of pain during inferior alveolar nerve block (IANB) anesthesia and evaluate the needle tip for mechanical deformation. MATERIALS AND
methodsSixty-six children 5-7 years old, who were indicated for IANB anesthesia, were selected from the outpatient clinic of Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University. Participants were randomly allocated into two groups according to the type of needle bevel used. Group I (n = 33) received INAB anesthesia using double scalpel blade bevel needle, while group II (n = 33) received the injection using conventional bevel needle. Pain reaction was evaluated subjectively using modified Maunuksela face pain scale (FPS) and objectively using Sensory, Eye, and Motor (SEM) scale. After the respective injections, the needles were prepared for microscopic examination.
resultsThe FPS and SEM showed significantly lower pain scores during IANB anesthesia with double scalpel blade bevel needle compared to the conventional bevel needle (p = 0.002, p = 0.003 respectively). No significant difference in mechanical angle deformation between the two needles was observed (p = 0.837).
conclusionFor IANB anesthesia, double scalpel blade bevel needle demonstrated significantly less injection pain. All dentalneedles demonstrated tip deformation after single use.
