Massage Method of Toothpaste Application can protect against Tooth Decay
A new study was carried out in Sweden to find out the effect of using a toothpaste with a high fluoride content (5000 ppm F) or a standard toothpaste with a normal fluoride content (1450 ppm F) two to three times a day on the retention of fluoride in plaque and saliva, and on the pH drop in plaque. The research, which has been published in the journal Acta Odontologica Scandinavia, was carried out under the leadership of Dr. Anna Nordström from the Sahlgrenska Academy at the University of Gothenburg, Sweden.
The research was carried out on 16 subjects, who were randomly allocated six different brushing regimes:
1. Brushing with a 5000 ppm F toothpaste two times daily
2. Brushing with a 5000 ppm F toothpaste three times daily
3. Brushing with a 5000 ppm F toothpaste two times daily, plus massaging the gums with the toothpaste using the fingertips, once a day
4. Brushing with a 1450 ppm F toothpaste two times daily
5. Brushing with a 1450 ppm F toothpaste three times daily
6. Brushing with a 1450 ppm F toothpaste two times daily, plus massaging the gums with the toothpaste using the fingertips, once a day
The researchers measured the fluoride retention in plaque and saliva, and the change in plaque-pH after a sucrose rinse.
It was observed that the fluoride retention was higher when the participants used the toothpaste with a fluoride concentration of 5000 ppm. There was a 3.6 times higher F saliva value when the participants brushed thrice daily with 5000 ppm F toothpaste compared to when they brushed twice daily with a 1450 ppm F toothpaste. Moreover, brushing twice along with massaging the gums once daily amounted to the same F saliva value as brushing thrice daily. Therefore the researchers opined that massaging the gums with the toothpaste is an inexpensive and effective way of protecting the teeth against tooth decay.
