The effect of preoperative low-level laser therapy on pain, swelling, and trismus associated with mandibular third molar extraction.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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 effect of low-level laser therapy (LLLT) applied before mandibular third molar extractions on postoperative pain, swelling, and trismus. MATERIALS AND
methodsThe study included 28 patients aged 18-45 years with bilaterally impacted mandibular third molars in similar positions, indicated for extraction based on clinical and radiographic examinations. Patients were divided into two groups: Group 1 received LLLT 10 min before surgery, while Group 2 (control group) underwent routine impacted tooth extraction after applying blue LED light. Measurements were taken preoperatively and at 24 h (T0), 48 h (T1), and 7 days (T2) postoperatively to assess the effects of LLLT on pain, swelling, and trismus. Statistical analysis was performed using the Jamovi 2.2.5 software. Due to the non-normal data distribution, the Friedman test was used for repeated measures within groups, while the Mann-Whitney U test was employed to compare the laser and control groups.
resultsThe study included 23 female (82.14%) and 5 male (17.86%) patients, with a mean age of 21.34 ± 4.37 years. No statistically significant differences were observed between the laser and control groups concerning pain, trismus, and swelling at T0, T1, and T2 (p > 0.05).
conclusionWithin the limitations of this study, preoperative LLLT showed clinically acceptable effects on postoperative pain, swelling, and trismus. Further clinical studies are needed to evaluate the long-term success of LLLT.
