Teacher supervised toothbrushing reduces dental decay in socially deprived school children

Dental decay is one of the most common preventable health problems in children living in socially deprived areas of the UK. Children living in low-socioeconomic neighbourhoods tend to start brushing their teeth at a later age and use fluoride containing toothpaste less often and, therefore, experience higher levels of dental decay overall. As a result, rates of tooth decay in five-year-olds have not improved in the last 10 years.

A study conducted by scientists from the Oral Health Research Centre, London, and published in Caries Research (1), reported that daily teacher supervised toothbrushing, during school term time only, reduced the occurrence of tooth decay by 11% in 5-year-old children living in a socially deprived region of London, over a period of 21 months.

A total of 370 first year primary school children (aged 5 years) in a London borough completed the study. Half of the children brushed their teeth once a day at school (after lunch but before afternoon lessons) with commercially available fluoride toothpaste under the supervision of their teacher. No supplementary dietary or dental health advice was given to the children or their parents.

A significant overall reduction in tooth decay was reported in all children. Looking solely at those with previous dental decay, the reduction in dental decay becomes even more apparent. A 30% reduction in further dental decay was noted in this group. Greater protection was seen in primary (milk) teeth than in permanent (second) teeth.

This study illustrates the fact that a programme of daily supervised toothbrushing, using fluoridated toothpaste, can be effectively integrated into socially deprived communities to achieve a significant reduction in dental decay in primary school aged children, without any changes to diet. It is well recognised that the introduction and use of fluoridated toothpaste has been the most important factor in the general decline in dental decay in children. Regular toothbrushing with fluoridated toothpaste has a greater impact on dental health than the restriction of sugary foods and beverages (2).
