Improving oral health: a short-term split-mouth randomized clinical trial revealing the superiority of resin infiltration over remineralization of white spot lesions

Youssef, Ahmed / Farid, Mohamed / Zayed, Mohamed / Lynch, Edward / Alam, Mohammad K. / Kielbassa, Andrej M.Page 696 - 709Objectives: To evaluate masking effects of resin infiltration on labial white spot lesions (WSL), by comparing the latter with a remineralization approach (using hydroxyapatite and fluorides) and conventional oral care (using fluoride-free toothpaste).Method and materials: Fifteen patients with at least three WSL were enrolled for a within-person randomized controlled trial, thus allowing for intrapersonal comparisons. Each WSL per tooth in every patient was randomly assigned to one of the following groups. Group 1: lesions were resin-infiltrated with Icon (RI; DMG); Group 2: Remin Pro (RP; VOCO) was used as remineralizing agent; and Group 3 (control): affected teeth were brushed with Complete Care toothpaste (CC; Himalaya). RP and CC were applied by means of a polishing brush, using a low-speed handpiece (5 min), and these procedures were repeated chairside thrice daily for 7 consecutive days. Digital photographs were captured before and after lesion treatment under standardized conditions. The CIE L*a*b* color system was used to analyze the optical outcome, and intrapersonal color differences were statistically evaluated.Results: Compared to RP and CC, RI showed prompt and subjectively satisfactory color improvements, and this was primarily driven by L* and b* shifts. Statistical analysis of the objective color differences ( ΔE*) between the three groups...
