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

Table 1

Succinate dehydrogenase enzyme (SDH) production by human gingival fibroblasts detected by the MTT assay according to the energy dose used in the low-level laser therapy.

Energy dose (J/cm^2)	MTT (%)
0 (control)	100 (96–104) C^*
0.5	111 (110–113) B
1.5	94 (92–97) D
3	117 (113–119) A
5	95 (81–108) CD
7	92 (91–96) D

Values expressed as medians of SDH production (P25–P75) (𝑛=12). ^*Same letters indicate no statistically significant difference (Mann-Whitney, 𝑃>0.05).
