Infiltrants for Aesthetic Treatment of White Spots Lesions by Fluorosis: Case Report

Abstract

Dental fluorosis is an abnormality in the development of enamel due to the excessive intake of fluoride during formation of dental tissues, mainly characterized by hypomineralization and increased porosity of the enamel structure. Oftenly the spots caused by dental fluorosis can compromise the aesthetics of the patient and affect their self-esteem. In recent years a new generation of dental materials has been developed, known as resin infiltrants, which are basically low viscosity resins that infiltrate and paralyze the progression of incipient non cavitated carious lesions. When resin infiltrants have been used to stop carious lesions it has been verified that they also produce changes in the appearance of white spots, masking or making them imperceptible. The present article describes a case report of the use of resin infiltrants for aesthetic treatment of white spot lesions caused by fluorosis.

Dental fluorosis: a review

“…In recent years, a new, more conservative approach has been developed to stop and control initial carious lesions, using the technique with infiltrative resins, which are characterized by their low viscosity, allowing the intercrystalline spaces in the demineralized enamel to be filled, occluding the microporosities that they can act as a diffusion route for acids and dissolved materials, thus achieving the formation of a barrier within the lesion, 14 recent scientific evidence has shown that they can be used to treat dental fluorosis. [15][16][17] The low-viscosity photopolymerizable resin allows rapid penetration into the porous enamel capable of inhibiting demineralization, masking the lesions and obliterating the microporosities within the lesion. 18 When performing the infiltrating resin technique, (Figure 3) the tooth structure is preserved, it mechanically stabilizes the structure of the demineralized enamel, it occludes the micropores in the body of the lesion, there is an absence of post-treatment sensitivity and pulp inflammation, it reduces the probability of gingivitis and periodontal disease, it stops the progression of lesions and reduces the recurrence of cavities without the need to make a cavity, it does not require anesthetics, it provides excellent aesthetic results in a single visit and it is possible to obtain good acceptance by patients.…”

Resinas infiltrativas como tratamiento para la fluorosis dental. Una revisión de literatura.

“…Las resinas infiltrativas ICON® tiene como principal compuesto matriz orgánica a base metacrilato, específicamente monómero trietilenglicol dimetacrilato (TEGDMA), iniciadores y aditivos (4,8). Es un material hidrófilo y sin relleno; además, la tensión superficial y el coeficiente de penetración son altas (5).…”

“…Respecto al índice de Thylstrup y Fejerskov, brinda una escala del cero al nueve en la que evalúa las características clínicas en relación a los cambios histológicos que ocurren en los diferentes niveles de gravedad en la fluorosis, incluso de la acumulación de flúor en esmalte, mostrando criterios de validez biológica (15). Con mayor precisión, en la fluorosis leve se observan líneas opacas con zonas blanquecinas, en los casos de fluorosis moderada la mayoría de la superficie se encuentra opaca e incluso con cráteres y por último en la fluorosis severa la superficie del esmalte puede estar perdida en su totalidad dejándola susceptible a fractura, además la lesión puede adquirir un tono marrón (4,19).…”

“…Este material está siendo empleado para interrumpir la progresión de lesiones cariosas proximales sin estar cavitada; sin embargo, evidencia científica reciente ha demostrado que pueden ser utilizadas para tratar la fluorosis dental (1,4,5).…”
