1 A young mother is concerned to learn that her 5‐year‐old son has several areas of demineralisation and two cavities in his deciduous teeth when checked by the dentist, as she ensures his teeth are brushed twice daily with ‘milk teeth’ type toothpaste. The dentist explains that this type of toothpaste has too little fluoride for children over 3 years of age. Which two of the options listed are the most likely fluoride concentrations that the dentist will recommend for regular toothbrushing and use for topical fluoride applications to the child, in ppm?

The correct answers are a) and c).All children over 3 years of age should be using toothpastes with the adult concentration of fluoride at 1450 ppm, to provide the maximum level of protection to their deciduous teeth and then their permanent teeth as they erupt. At each recall appointment, the child should also have a fluoride gel applied to all his teeth to help strengthen them against further carious attack. The gels are typically a fluoride strength of 22,600 ppm.

1 Modern toothpastes contain many different constituents, and some patients may find it difficult to determine which product is best for their specific oral health needs. The dental team are well placed to advise patients about the most suitable products available for their particular needs, depending whether they require products to combat dental caries or periodontal disease. Which two of the options listed are constituents that may be found in a toothpaste designed to protect against caries and relieve sensitivity?

The correct answers are g) and h).Fluoride is the ingredient present to protect against dental caries, and many toothpastes contain it as sodium fluoride at 1450 ppm. Stannous fluoride is present in some ‘sensitivity’ toothpastes to help reduce the electric shock‐type sensation that some patients experience with cold drinks, foods or when breathing in cold air.
