PURPOSE: This pilot study aimed to evaluate whether replacing nighttime ibuprofen with melatonin, vitamin D, and vitamin B12 (chronotherapy) improves postoperative recovery after third molars extraction, and to explore sex-dependent responses.
METHODS: A double-blind, randomized, two-period pilot crossover trial was conducted with 12 healthy adults undergoing bilateral mandibular third molars extraction. In the control period, participants received ibuprofen 400 mg three times daily. In the chronotherapy period, the nighttime ibuprofen dose was replaced with melatonin (10 mg), vitamin D (1000 IU), and vitamin B12 (1000 µg). Outcomes included pain intensity (Visual Analogue Scale [VAS]), facial swelling, trismus, rescue medication use, and inflammatory cytokines.
RESULTS: Overall, chronotherapy was associated with higher postoperative pain, increased vertical swelling, and reduced trismus compared with control. Significant treatment-by-sex interactions were observed. Female participants reported statistically higher, although clinically insignificant, postoperative pain scores with chronotherapy (mean VAS increase: +0.94 points, p < 0.001), along with greater swelling but less restriction in mouth opening. In contrast, males showed similar pain levels but a shorter time to pain cessation and reduced swelling with chronotherapy. Exploratory cytokine analyses suggested broader increases in pro- and anti-inflammatory mediators in males receiving chronotherapy (e.g., IL-10, IL-13), whereas females showed limited cytokine changes.
CONCLUSION: Replacing nighttime ibuprofen with the chronotherapy regimen did not appear to improve overall postoperative pain outcomes. However, chronotherapy may produce sex-dependent postoperative responses, with mixed recovery patterns in females and modest benefits in selected outcomes in males. Given the pilot nature of the study and limited sample size, these findings should be considered exploratory and hypothesis-generating.
