Adjunctive postoperative vitamin B complex with ibuprofen for pain and soft-tissue healing after impacted mandibular third molar surgery: a split-mouth randomized clinical trial.

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
purposePain and delayed soft-tissue healing are common after mandibular third molar surgery. This study aimed to assess the effect of vitamin B complex supplementation on pain and healing after surgical extraction of mandibular third molars.
methodsThis double-blind split-mouth randomized clinical trial was conducted on 17 patients requiring bilateral extraction of mandibular third molars. In each patient, one quadrant was randomly assigned to the intervention group and the contralateral quadrant to the control group. Patients received ibuprofen plus placebo after surgical extraction of the control quadrant and ibuprofen plus vitamin B complex after surgical extraction of the intervention quadrant. Postoperative pain was assessed using a visual analog scale (VAS) at 1, 6, 12, 24, 48, and 72 h after surgery. Soft-tissue healing was evaluated at 2 and 3 weeks using a 3-point healing scale. Data were analyzed using Friedman and Wilcoxon signed-rank tests with Bonferroni correction.
resultsSeventeen patients completed both surgical procedures and follow-up assessments. Significant differences in postoperative pain were observed across treatment conditions and time points (P < 0.001). Compared with placebo, adjunctive vitamin B complex significantly reduced pain at 48 h (P = 0.005) and 72 h (P < 0.001), whereas no significant differences were observed at 1 h (P = 0.426), 6 h (P = 0.112), 12 h (P = 0.621), or 24 h (P = 0.077). Healing was not significantly different between groups at 2 weeks (P = 0.317); however, healing was significantly improved in the vitamin B complex group at 3 weeks (P = 0.011).
conclusionsWithin the limitations of this study, postoperative vitamin B complex supplementation as an adjunct to ibuprofen was associated with reduced pain at 48-72 h and improved soft-tissue healing at 3 weeks after mandibular third molar extraction. Larger randomized clinical trials are warranted to confirm these findings.
