From: Intraoral photobiomodulation-induced orthodontic tooth alignment: a preliminary study
Boxplots showing alignment rates (mm/week) for control and PBM treated patients. Whiskers represent 1.5-times the interquartile ranges. Outliers are included. A statistically significant difference (p = 0.0002) in alignment rate was found between the two groups. The PBM group’s mean alignment rate was 1.27 (Interval of 1.01-1.53 at 95 % confidence), compared to a control rate of 0.44 (Interval of 0.30-0.59 at 95 % confidence) with a comparison group of 10 control arches and 18 PBM-treated arches
