In Vitro Wound Healing Improvement by Low-Level Laser Therapy Application in Cultured Gingival Fibroblasts

Table 2

Number of viable cells (%) detected by the trypan blue assay, according to the energy doses used in the low-level laser therapy.

Energy dose (J/cm^2)	Number of viable cells (%)
0 (control)	100 (95–104) B^*
0.5	133 (112–175) A
3	168 (149–181) A

Values expressed as medians of SDH production (P25–P75) (𝑛=8). ^*Same letters indicate no statistically significant difference (Mann-Whitney, 𝑃>0.05).
