Zinc hydroxyapatite and Calcium sodium phosphosilicate toothpaste reduce dental sensitivity and periodontal disease indicators, making them an encouraging oral care option for paediatric patients with asthma and allergic rhinitis.
Innovative toothpastes with biomimetic and re-mineralising properties have been shown to have great potential against enamel demineralisation as observed in recent years.
A Scribante and co-authors compared two toothpastes that help remineralize teeth in children with asthma and allergic rhinitis after a six-month treatment period. At the University of Pavia's, Unit of Dental Hygiene (Italy), 40 patients (aged 6 to 14 years) with enamel demineralizations, aged 6 to 14, participated in a randomized trial.
Patients were split evenly into two groups following mechanical debridement using piezoelectric instruments and glycine powder. Group 1 used toothpaste containing Zinc hydroxyapatite, while Group 2 used toothpaste with Calcium sodium phosphosilicate to be used twice a day on a soft bristle toothbrush. The study period of analysis was at baseline and after 1 month, 3 months and 6 months.
The use of these toothpastes greatly reduced different indices- plaque, bleeding on probing (bleeding gums), and Schiff air index in these patients over six months. Both groups saw similar improvements with no notable differences between them. Interestingly, while Group 1 showed a significant decrease in susceptibility index from the second to the third month, Group 2 did not. Other measures like salivary pH, decayed missing filled teeth, and Basic Erosive Wear Examination remained unchanged across all groups.
