Has taken an anti-inflammatory medication which, in the opinion of the investigator, could affect gingival condition in the previous 14 days. iii. Has taken a systemic medication which, in the opinion of the investigator, could affect gingival condition in the previous 14 days (e.g. calcium channel blockers, or aspirin therapy).could affect gingival condition in the previous 14 days (e.g. calcium channel blockers, or aspirin therapy).Investigator, could affect gingival condition (e.g. calcium channel blockers, or aspirin therapy). -Have current active caries or periodontitis that may, in the opinion of the investigator, compromise the study or the oral health of the subjects if they participate in the study. -Restorations in a poor state of repair.
- Partial dentures or orthodontic appliances. -Teeth bleaching within 12 weeks of screening. -Use of a chlorhexidine mouthwash within 14 days of baseline. -Current smokers or smokers who have quit within the past 6 months prior to screening or subjects currently using smokeless forms of tobacco, e.g. Gutkha, Pan containing tobacco, Pan Masala or nicotine based e-cigarettes.
