Developmental defects of enamel (DDEs) are visible alterations in the normal translucency of enamel resulting from enamel organ dysfunction. Clinically DDEs can be seen as qualitative or quantitative defects. Qualitative developmental defects are further characterised by an intact surface layer which is smooth and hypermineralised, and a porous subsurface layer, that is soft and hypomineralised. Affected teeth pose significant clinical challenges6,7 due to this characteristic structure. The presence of such defects significantly increase dental treatment need as the teeth are more susceptible to plaque accumulation and dental caries. There is rapid post-eruptive tissue loss associated with the teeth and increased porosity of residual enamel. Several treatment strategies have been suggested for DDEs, like micro abrasion, tooth bleaching, composite restorations, full crown restorations. Most of the treatment strategies that focus on aesthetic improvement, do not concentrate on the functional demands; like micro abrasion and bleaching. On the other hand, restorative procedures, which meet the functional demands, follow a much invasive protocol. In order to bridge the gap between the two have emerged the micro-invasive options. One of the most promising microinvasive alternative for DDEs is ‘resin Infiltration’. This new technique has been found to be highly effective in infiltrating natural early carious lesions which are structurally similar to qualitative developmental enamel defects. The present series of clinical cases therefore were planned to assess how effectively resin infitration procedure is able to recover the natural enamel esthetics.
