Table 1.

Intergroup comparison of the mean cell viability percentage for hydrogen water-treated fibroblasts obtained from periodontally healthy individuals and patients with chronic periodontitis after 24 h and 48 h

Group	Mean cell viability (%)*
	24 h	48 h
Hydrogen water-treated periodontally HF	87	88.6
Hydrogen water-treated fibroblasts from chronic periodontitis patients (CF)	80	73

*Considering the positive control has 100% viability. HF-Healthy fibroblasts; CF – Fibroblasts from patients with chronic periodontitis
