Evaluation of two different remineralising toothpastes in children with drug-controlled asthma and allergic rhinitis: a randomised clinical trial.

Abstract

Aim: To compare the efficacy of two remineralising toothpastes in children suffering from asthma and allergic rhinitis after a 6-month study.

Methods: 40 patients aged between 6-14 years with enamel demineralisations were enrolled for the study at the Unit of Dental Hygiene of the University of Pavia (Italy). The following indices were collected: Schiff air index (SAI), plaque index (PI), bleeding on probing (BoP), salivary pH, Basic Erosive Wear Examination (BEWE), susceptibility index (SI) for hard and soft tissues' pathologies, and decayed missing filled teeth (DMFT). After mechanical debridement with piezoelectric instrumentation and glycine powder, patients were equally divided into two groups: Group 1 using a toothpaste with zinc hydroxyapatite, and Group 2 using a toothpaste containing calcium sodium phosphosilicate. The toothpaste had to be used twice a day. The time frames of the study were: baseline (T0), after 1 month (T1), after 3 months (T2), after 6 months (T3).

Conclusion: The tested toothpastes can be proposed for home use in children with asthma and allergic rhinitis as they significantly reduced dental sensitivity and periodontal indices.
