Non-Cavitated Approach for the Treatment of White Spot Lesions: A Case Report

Abstract

Aim: White spot lesions (WSLs) are the most frequently observed problems in patients with poor oral hygiene. If this problem is left untreated during the initial phase, it will ultimately need major treatment. One treatment alternative in the initial phase is the caries infiltration technique. The aim of this case report is to present the treatment of WSLs by using this technique. Methodology: An 18-year-old female who had WSLs on the buccal surfaces of the lower left canine, first and second premolars and first molar after 8 months of fixed orthodontic therapy was included in this study. Icon-Infiltrant was applied for the treatment of WSLs. Results: After Icon-Infiltrant application, the WSLs were cured. Conclusions: By using this technique, an esthetic smile can be achieved in one visit with the elimination of esthetic discoloration and the progression of the early enamel lesions can be prevented.

Management of White Spot Lesions Using Resin Infiltration Technique: A Review

“…(11,12,18,19) Researchers reported that etching with phosphoric acid affected only the outermost 25µm of the surface. (20) However, superficial phosphoric acid etching causes the caries lesion to extend into the deeper enamel layers resulting in probable cavitation in the future. (20) The penetration depth of 15% HCL etching is more than twice (58 µm) that of phosphoric acid, enabling penetration into the deepest part of the lesion and eliminating the decalcified areas, preventing further attacks.…”

(13) The surface is then dehydrated with 99% ethanol (ICON Dry) to facilitate the drying process.…”

“…(27) Paris and Meyer-Lueckel (23) reported the first successful immediate improvement of esthetic appearance of white spot lesions that remained stable until the 10 th month of follow up. (23) Shivanna and Shiivakumar (2011) (45) , and Basaran et al (2011) (20) reported the successful immediate masking of post-orthodontic lesions in teeth treated with resin infiltration technique. Shivanna and Shiivakumar (2011) (45) reported result stability at the end of a 3-month review period.…”

Color Modifying Effect of Resin Infiltrant (icon) Versus Adhesive Resin on Aesthetic Correction of Enamel White Spot Lesion: RCT

“…White enamel discolorations are defined as the enamel lesions accompanied with a reduction of the mineral content and consequently render it to opaque and chalky white appearance [1] . They can occur as a consequence of either pre-or post-eruptive damage.…”

“…Application of hydrochloric acid as an etchant has been estimated to be superior to 37% orthophosphoric acid gel in removing the outer surface layer of enamel lesion (30-40mm) which hampers resin penetration into the lesion [7,10,21] . Studies reported that etching with orth-phosphoric acid affected the outermost 25mm of the surface layer [1] . Zamorano et al (2017), compared the penetration depth between an infiltrant resin and two adhesive systems but with use of their corresponding etching systems [22] .…”
