An Erosion Study to Investigate the Efficacy of an Experimental Dentifrice to Remineralize Enamel

Completed · Not applicable · Has a placebo group

Conditions studied: Tooth Erosion

In brief

The purpose of this study is to investigate the ability of an experimental dentifrice containing 1150 parts per million (ppm) fluoride to remineralize acid-softened dental enamel and help prevent further demineralization compared to a 0 ppm fluoride placebo dentifrice and a marketed, fluoride-containing dentifrice (Reference Dentifrice).

You may not qualify if…

Participant who is an employee of the investigational site, either directly involved in the conduct of the study or a member of their immediate family; or an employee of the investigational site otherwise supervised by the investigator; or, a Haleon employee directly involved in the conduct of the study or a member of their immediate family (employees of the study site and associated academic institutes who are not directly involved in the conduct of the study are eligible to be considered as participants.)
Participant who has participated in other studies (including non-medicinal studies) involving investigational product(s) within 30 days prior to study entry and/or during study participation.
Participant with, in the opinion of the investigator or medically qualified designee, an acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator or medically qualified designee, would make the participant inappropriate for entry into this study.

Participant taking medication that may interfere significantly with the saliva flow in the judgment of the investigator. Should new medications that may interfere with the saliva flow be added, a second salivary flow test will be performed.
Participant with any condition that would impact on their safety or wellbeing or affect their ability to understand and follow study procedures and requirements.
Participant with any sign of grossly carious lesions (active), moderate or severe periodontal conditions, or severe tooth wear. Participant presenting at screening with minor caries may continue in the study if their carious lesions are repaired prior to the first treatment visit of the study.
