Biomimetic Hydroxyapatite in Pediatric Patients With Asthma and/or Allergic Rhinitis

The aim of the study is to compare the incidence of dental caries and the level of demineralization in pediatric patients with asthma and/or allergic rhinitis. Patients will conduct professional oral hygiene at the baseline. The following clinical indexes will be assessed: BEWE Index, Plaque Index, Bleeding Score, Schiff Air Index. Then, patients will be randomly divided into two groups: * Trial group: domiciliary use of Biorepair Total Protection Plus + desensitizing enamel-repair shock treatment twice a day * Control group: domiciliary use of Elmex Caries Protection twice a day The clinical indexes will be assessed again after 1 month (T1), after 3 (T2) and 6 months (T3).
