Oral Care Product Trials

Oral Care consumer product studies and trials.

Intertek has extensive experience of conducting trials for oral care products, such as toothpastes, toothbrushes, mouthwashes, dental floss, and others.

Intertek calibrated assessors are familiar with most industry recognised dental indices. When combined with Intertek 4-Front's extensive range of biometric assessment equipment and our fully characterised volunteer database, we provide clients with the broadest range of product development and advertising support data.

Oral healthcare product studies and trials:

Dental plaque studies 

•  Dental plaque is considered to be a key aetiological factor in caries and gingivitis. Our assessors are familiar with a number of indices including Quigley and Hein, Loe & Silness and Navy to name a few. Additionally, we regularly conduct plaque sampling and analysis (microbiology, active agent deposition etc). 

Gingivitis studies 

• Sub-optimal oral hygiene may lead to gingivitis and a number of products aim to control this condition. We have experience of a number of study designs from 21 day, through to six months and are experienced in several indices including Gingival Index and Bleeding indices. Gingival Crevicular fluid sampling and elution can be conducted as required. 

Stain removal and whitening studies 

• The pursuit of a bright, white smile has lead to an explosion of stain control and whitening products. We have considerable experience of a number of protocols incorporating Lobene (MacPherson modification), Artificial stain build up, and Vita shade. 

Dental sensitivity trials 

• Dentinal hypersensitivity is a common and painful condition. Accurate diagnosis of the cause of any painful stimuli to exclude non-dentinal hypersensitivity aetiologies is key to running successful clinical trials in this area. Examples of indices used are Thermal stimuli as well as Pressure stimuli. 

Malodour trials 

• Control of bad breath has been identified as a key consumer need. Intertek 4-Front has trained malodour assessors as well as instrumental assessments. 

Caries 

• Intertek has a number of in-situ models to assess the changes in microhardness of enamel and dentine. 

Calculus 

• The removal of calculus remains the preserve of the dentist and hygienist. Controlling build up of Calculus by both chemotherapeutic and mechanical means can be measured using the Volpe-Manhold Index. 

Dental abrasivity studies 

• We have an in-situ model which allows assessment of enamel and dentine abrasion on real dental tissue, subjected to the rigours of a normal oral environment. Example methodologies are In situ enamel wear, In situ dentine wear and In vivo toothbrush abrasion (soft tissue).
