ABSTRACT
OBJECTIVE:
To evaluate the effect of the probiotic Lactobacillus brevis CD2 on the prevention of early traumatic oral lesions induced by a fixed orthodontic appliance. SETTINGS AND SAMPLE POPULATION Twenty orthodontic patients (14-57 yo) were recruited from a private clinic. SUBJECTS ANDMETHODS:
In a phase 2, double-blind clinical trial, all patients were randomly allocated (11 ratio) to a 21-day course of soluble tablets containing L brevis CD2 (4 billion colony-forming units after breakfast, lunch and dinner) or placebo, starting at the day of orthodontic appliance placement. The primary outcomes were days with oral lesions and lesion-related pain [ranging between 0 (no pain) and 10 (maximum pain)]. Oral health-related quality of life was measured using OHIP-14 before and after treatments.RESULTS:
All patients completed the study. Ten were treated with L brevis (28.1 ± 13.3 yo, 70% women), and 10 received placebo (27.5 ± 9.1 yo, 60% women). The oral lesions lasted significantly less time (P = .018) in patients treated with L brevis (2.5 ± 1.0 days) than with placebo (4.9 ± 3.0 days). Pain score was significantly lower (P = .039) when L brevis was used [median (min-max) 0 (0-4) vs. 3 (0-5)]. OHIP-14 scores were not significantly different between treatments.CONCLUSIONS:
Lactobacillus brevis CD2 reduced almost 50% the persistence of traumatic oral lesions in patients with fixed orthodontics. Yet, there was no improvement in quality of life compared to placebo, suggesting that such differences in persistency and pain related to oral lesions may be considered clinically irrelevant.Palabras clave
