Treatment of Temporomandibular Dysfunction With Hypertonic Dextrose Injection (Prolotherapy): A Randomized Controlled Trial With Long-term Partial Crossover
Bibliographic record
Abstract
OBJECTIVE: To assess the efficacy and longer-term effectiveness of dextrose prolotherapy injections in participants with temporomandibular dysfunction. PATIENTS AND METHODS: A randomized controlled trial with masked allocation was conducted from January 14, 2013, through December 19, 2015. Forty-two participants (with 54 joints) meeting temporomandibular dysfunction criteria were randomized (1:1) to 3 monthly intra-articular injections (20% dextrose/0.2% lidocaine or 0.2% lidocaine) followed by as-needed dextrose/0.2% lidocaine injections through 1 year. Primary and secondary outcome measures included a 0 to 10 Numerical Rating Scale score for facial pain and jaw dysfunction; maximal interincisal opening (MIO) measured in millimeters, percentage of joints with 50% or more change (improvement) in pain and function, and satisfaction. RESULTS: Randomization produced a control group with more female participants (P=.03), longer pain duration (P=.01), and less MIO (P=.01). Upon 3-month analysis, including pertinent covariates, dextrose group participants reported decreased jaw pain (4.3±2.9 points vs 1.8±2.7 points; P=.02), jaw dysfunction (3.5±2.8 points vs 1.0±2.1 points; P=.008), and improved MIO (1.5±4.1 mm vs -1.8±5.1 mm; P=.006). Control group participants received dextrose injections beginning at 3 months. No between-group differences were noted at 12 months; pooled data suggested that jaw pain, jaw function, and MIO improved by 5.2±2.7 points (68%), 4.1±2.8 points (64%), and 2.1±5.5 mm, respectively. Pain and dysfunction improved by at least 50% in 38 of 54 (70%) and 39 of 54 (72%) jaws, respectively. CONCLUSION: Intra-articular dextrose injection (prolotherapy) resulted in substantial improvement in jaw pain, function, and MIO compared with masked control injection at 3 months; clinical improvements endured to 12 months. Satisfaction was high. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01706172.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
