Randomisation	Margin	0.27 ± 0.078	0.27 ± 0.076
Randomisation	Papillae	0.20 ± 0.078	0.19 ± 0.080
Week 12^*	Margin	0.37 ± 0.155	0.49 ± 0.171
Week 12^*	Papillae	0.32 ± 0.154	0.44 ± 0.186

Between treatment differences based on model-adjusted means were statistically significant (P < 0.0001) in favour of 0.1%w/w o-cymen-5-ol/ 0.6%w/w zinc chloride (ZnCl₂) dentifrice for margin and papillae.
