Background: Dental caries remains the most global widespread disease. To deal with dental caries in a minimal invasive technique, attempts were made to remineralize affected dentine to improve its physical properties.
Objectives: This study aimed to assess the clinical and radiographic success of applying Casein Phosphopeptide Amorphous Calcium Phosphate (CPP-ACP) under glass ionomer restorations in primary teeth treated with Atraumatic Restorative Treatment (ART).
Materials and method: Forty primary molars from patients attending the pediatric dentistry clinic were selected for clinical and radiographic assessments after fulfilling the inclusion criteria. The study sample was divided randomly into 2 groups: Group I: 20 molars treated with CPP-ACP varnish then restored with glass ionomer restoration. Group II: 20 molars restored only with glass ionomer restoration. Cavity preparation included the removal of the infected dentine and conserving the affected dentinal tissue. Clinical and restoration assessments were carried out at 1 and 6 months while the radiographic assessment was done at baseline and 6 months.
Results: No significant differences were shown between the 2 groups after 1 and 6 months when comparing the clinical success of CPP-ACP and success of the restoration used with ART. Moreover, no significant differences were found regarding radiographic success after 6 months.
Conclusions: The use of CPP-ACP before applying RMGI restorations in primary teeth proved to be a successful technique in class I ART restorations, allowing a painless anesthesia-free dental visit and decreasing the incidence of pulp exposure.
