Pre-Prophy Baseline	Margin	1.88 ± 0.209	1.90 ± 0.193
Pre-Prophy Baseline	Papillae	1.89 ± 0.213	1.92 ± 0.199
Randomisation	Margin	0.47 ± 0.252	0.45 ± 0.236
Randomisation	Papillae	0.44 ± 0.266	0.42 ± 0.257
Week 6^*	Margin	1.51 ± 0.206	1.75 ± 0.190
Week 6^*	Papillae	1.52 ± 0.213	1.76 ± 0.198
Week 12^,^*	Margin	0.98 ± 0.262	1.57 ± 0.188
Week 12^,^*	Papillae	0.93 ± 0.280	1.55 ± 0.200

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.
