Abstract

White spot lesions caused by enamel demineralization are frequently encountered in dental practice. Their management has always been an important issue in modern dentistry. However, the real dilemma was treating aesthetic demands with noninvasive or minimally invasive techniques preserving the natural tissues. The introduction of resin infiltration technique seems to provide an intermediary treatment modality between prevention and restorative therapy. This case report is aimed at reporting the management of MIH opacities in anterior teeth with resin infiltration technique.

Highlights

White spot lesions (WSLs), defined as “white opacity,” occur as a result of subsurface enamel demineralization that is located on smooth surfaces of teeth [1]
Molar-incisor hypomineralization (MIH) is defined as a developmental condition characterized by hypomineralization defects of the enamel on the first permanent molars associated with the permanent incisors
This paper is aimed at describing and illustrating the aesthetic management of white opacities caused by molar-incisor hypomineralization (MIH) using a resin infiltration technique

Summary

Introduction

White spot lesions (WSLs), defined as “white opacity,” occur as a result of subsurface enamel demineralization that is located on smooth surfaces of teeth [1]. Molar-incisor hypomineralization (MIH) is defined as a developmental condition characterized by hypomineralization defects of the enamel on the first permanent molars associated with the permanent incisors. The defining clinical features of MIH are demarcated opacities with clear, distinct borders with the adjacent enamel. The opacities range from white to yellow/brown in appearance, and in lesions with a severe mineral deficit, rapid progression to posteruptive enamel breakdown can occur [5]. Several techniques have been proposed to improve the appearance of MIH spot lesions. This paper is aimed at describing and illustrating the aesthetic management of white opacities caused by MIH using a resin infiltration technique
