Influence of ozonized water on pain, oedema, and trismus during impacted third molar surgery: a randomized, triple blind clinical trial
Abstract
Background: This study aimed to evaluate the efficacy of ozonized water on pain, oedema and trismus after impacted third molar mandibular surgeries when compared to double distilled water. A randomized triple blind trial was conducted.
Methods: Patients with third molars class II-B of Pell-Gregory were included, and surgical extraction was performed. Irrigation was done with ozonized (group 1) or double distilled water (group 2). The type of irrigation and the side to be operated were randomized. Neither the patients nor the operator or evaluator were aware of the irrigation solution. Pain, oedema and trismus were evaluated at baseline, 24-h, 48-h, 72-h and 7-days after treatment. The data were evaluated by Friedman, Wilcoxon, Mann-Whitney tests, and size effect.
Results: It was included 8 men and 12 women, with a mean age of 20.9y.o. The initial pain mean was 7.94 (±12.81) (group 1) and 5.50 (±9.12) (group 2) (p > 0,05). There was a statistically significant reduction of pain, oedema and trismus in intragroup analysis (p 0.05) when comparing the oedema and trismus between groups. The size effect ranged from small (0.23) to large (1.29).
Conclusions: It was concluded that ozonized water was compatible as irrigation method, not inferior to double distilled water, and had satisfactory effects on management of pain, oedema and trismus after surgical removal of the third molar.
Trial registration: This clinical trial was registered in ClinicalTrials.gov NCT03501225 on April 18,…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 12 participants or records.
