Three Dimensional Assessment of Radiographic Changes after Indirect Pulp Capping using Silver Diamine Fluoride with or without Potassium Iodide in Young Permanent Teeth (12-month RCT)

The aim was to have a three-dimensional evaluation of radiographic changes after indirect pulp capping (IPC) with silver diamine fluoride (SDF) with or without potassium iodide (KI) and resin modified glass ionomer cement (RMGIC) in deep carious young permanent molars using cone beam computed tomography (CBCT). 108 first permanent molars with deep occlusal cavitated caries lesions, in forty-nine 6 –9-year-old children, were randomly allocated to one of 3 groups (n=36) and treated with SDF+KI, SDF and RMGIC as IPC materials. CBCT scans were taken at 0 and at 12-months to assess tertiary dentin formation (volume and grey level intensity), increase in root length, and pathological changes as s econdary caries, periapical radiolucency, internal resorption and obliteration of the pulp. The three-dimensional image analysis procedures were performed using ITK-SNAP and 3D Slicer CMF. Comparisons were made using analysis of variance with a fixed effect for treatment and random effects for patie nt, and patient-by-treatment to account for within-patient correlations. A two-sided 5% significance level was used. There were no significant differences among the three groups regarding tertiary dentin volume (p=0.712) and grey level intensity (p=0.660), increase in root length (p=0.365), preventi on of secondary caries (p=0.63) and periapical radiolucency (p=0.80) in the analysed 69 CBCT scans. The study did not find differences among the groups regarding quality and quantity of tertiary d...
