RESUMO
ABSTRACT: Purpose: To provide an overview of different indications suitable for treatment with the technique of resin infiltration (Icon, DMG), such as white-spot lesions (WSL), enamel fluorosis, and molar-incisor hypomineralisation (MIH), and to propose a valid and strategy feasible in dental surgeries for screening of dental color improvement and -stability. Method: A non-systematic review of the literature was performed to characterise inhibition of lesion progression, and the esthetic effects induced by resin infiltration of decalcified enamel, enamel fluorosis, and molar-incisor hypomineralisation (MIH), using the online database Pubmed and a suitable search strategy. Database search was complemented by a hand-search of references of retrieved articles. Results: Of 34 retrieved articles, 29 were included in the review. Evidence of an assimilation of WSL color to surrounding enamel following infiltration is available on the level of RCTs, and the results were found to be stable in color with no significant changes over at least twelve months. Evidence of an esthetic improvement of fluorotic or MIH affected teeth is available on the level of case reports and case control studies. Conclusion: As a micro-invasive approach to infiltrate and seal different types of enamel lesions, with a subsequent improvement of the esthetic appearance, resin infiltration is considered to be a useful complementation of the dental therapeutic specter.

To treat initial caries lesions using the technique of resin infiltration for a restoration of natural enamel appearance. Case report of a 19 year old female who presented with moderate post-orthodontic white-spot lesions (WSLs) at the upper central and lateral incisors following two years of active treatment with a fixed orthodontic appliance, and requested an aesthetic improvement of decalcified enamel surfaces. The technique of resin infiltration (Icon®, DMG, Hamburg, Germany) is presented as a means for not only inhibiting lesion progression, but also for an adequate rehabilitation of dentofacial esthetics. Practical tips and cues for clinical handling of the infiltration technique are provided. Resin infiltration augments the therapeutic spectrum for orthodontist as well as pediatric or general dentists in that enamel areas affected by post-orthodontic WSLs can be restored to their original appearance.
El objetivo fue mostrar el tratamiento de lesiones de caries iniciales usando la técnica de infiltración de resina para una restauración de la apariencia natural del esmalte. Reporte de caso de una joven de 19 años de edad, de sexo femenino que presentó lesiones moderadas de manchas blancas (WSLs) en los incisivos centrales y laterales superiores, luego del tratamiento de ortodoncia con aparatos fijos por dos años, y solicitó una mejoría estética de las superficies descalcificadas del esmalte. La técnica de infiltración de resina (Icon®, DMG, Hamburgo, Alemania) se presenta como un medio efectivo, no sólo para inhibir la progresión de la lesión, sino también para una rehabilitación adecuada de la estética dentofacial. Se proporcionan además consejos prácticos y claves para el manejo clínico de la técnica de infiltración. La infiltración de resina aumenta el espectro terapéutico del ortodoncista, así como de odontopediatras y odontólogos generales en las áreas del esmalte afectadas con WSLs post-ortodoncia y que pueden ser restauradas a su apariencia original.
