International Journal of Paediatric Dentistry 2012; 22: 427–434 Aims. To ascertain whether deproteinization pretreatment of molar‐incisor hypomineralization (MIH) enamel affects resin sealant infiltration. Design. Thirty one extracted MIH teeth were divided into three sections and randomly allocated into the Control (etch and FS), Treatment 1 (5% NaOCl, etched and fissure sealed), and Treatment 2 (5% NaOCl and fissure sealed with no etch) groups. Two hundred seventy nine sealant tag/enamel grade observations were recorded by scanning electron microscopy. Results. Control and Treatment 1 were similar in their outcomes, and Treatment 2 was markedly different. There was no statistical evidence to suggest that there was any difference between Treatment 1 and the Control Treatment (95% CI, 0.52, 1.51; P = 0.6). There was a marked difference between Treatment 2 and the Control Treatment (95% CI, 0.07, 0.25; P < 0.001). All treatments also demonstrated a high‐predicted probability of obtaining ‘poor’ sealant tags (Control = 47%, Treatment 1 = 49%, and Treatment 2 = 40%). Conclusions. The findings suggest that there was no significant difference in the tag quality between the conventional technique (Control) and the ‘bleach‐etch‐seal’ technique (Treatment 1). There was no benefit in pre‐treating with NaOCl alone (without etch) before sealing. This research also showed that there was a high‐predicted probability of obtaining ‘poor’ sealant tags in MIH enamel, regardless of which of the three treatments was used.
