Handheld point-of-care ultrasound for chairside assessment of masseter muscle: a pilot study.
Article in Oral radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 assess the feasibility of handheld ultrasound for scanning and measuring masseter muscle thickness.
methodsThis prospective pilot study included adult participants aged 18 and older. Inclusion criteria specified healthy individuals without pain or a TMD diagnosis in the last six months and not receiving neuromodulators as a treatment for TMJ-related issues. Exclusion criteria included individuals with developmental disorders affecting the craniofacial skeleton or with connective tissue and dermatological disorders impacting skin thickness. A scanning protocol was developed for a new handheld ultrasound system [4-12 MHz; (Lumify, Philips, USA)] to assess the masseter muscle thickness of participants in relaxed and clenched states.
resultsTwo evaluators analyzed ninety-two ultrasound scans from 12 participants. Intraclass correlation coefficient and standard deviations between the observers were calculated. Reliability for masseter measurements ranged from good to excellent (ICC 0.84-0.93) for Intra-observer and excellent for Inter-observer (ICC 0.93-0.98).
conclusionThe preliminary findings of this study demonstrate the high reliability of handheld ultrasound in assessing masseter muscle. The results support the use of handheld ultrasound to assess masseter muscle thickness. This system can be an alternative to cart-based systems facilitating the implementation of ultrasound as a chair-side tool in dentistry.
