Randomisation	Margin	0.25 ± 0.114	0.25 ± 0.108
	Papillae	0.16 ± 0.115	0.15 ± 0.106
Week 6*	Margin	0.34 ± 0.156	0.40 ± 0.156
	Papillae	0.23 ± 0.142	0.30 ± 0.147
Week 12*,**	Margin	0.17 ± 0.083	0.24 ± 0.104
	Papillae	0.08 ± 0.073	0.16 ± 0.107

^*Between treatment differences based on model-adjusted means were statistically significant (P < 0.0001) for week 6 and week 12 in favour of 0.1%w/w o-cymen-5-ol/ 0.6%w/w zinc chloride (ZnCl₂) dentifrice for margin and papillae.

^**N = 104 and N = 101 were assessed in each group respectively at Week 12.
