Treatment of Fluorosis Spots Using a Resin Infiltration Technique: 14-month Follow-up

Management of Enamel Defects with Resin Infiltration Techniques: Two Years Follow Up Retrospective Study

Background: Developmental Defects of Enamel (DDE) represent an aesthetic, functional, and often psychological problem, especially in young patients. Infiltrative treatment with resin (Icon-DMG, Hamburg, Germany) is a minimally invasive technique based on the infiltration of high viscosity resin inside the hypomineralized enamel, modifying its optical properties. The aim of this paper is to evaluate the clinical efficacy of superficial infiltration in the treatment of white enamel defects of the anterior sector with pre-eruptive etiology and its stability over time. Methods: Thirty-three patients affected by DDE associated with mild and moderate Molar Incisor Hypomineralization (MIH), mild and moderate fluorosis, and post-traumatic hypomineralization treated with resin infiltration were retrospectively retrieved. Results: In all cases an improvement in aesthetic appearance was achieved, and the 24-month follow-up confirmed the stability of the results. However, in the cases of traumatic hypomineralization the results were not completely satisfactory. Conclusions: The superficial infiltration technique can be considered a valid minimally invasive alternative to traditional treatment of mild or moderate fluorosis and mild MIH.

Clinical Efficacy of Resin Infiltration Technique Alone or in Combination with Micro Abrasion and in-Office Bleaching in Adults with Mild-to-Moderate Fluorosis Stains

Background:

The present study was conducted to evaluate the clinical efficacy of resin infiltration technique alone or in combination with microabrasion and in-office bleaching in adults with mild-to-moderate fluorosis stains on permanent maxillary anterior teeth at the end of 1 month.

Materials and Methods:

A total of 30 patients with nonpitted fluorosis stains on maxillary anterior were classified as mild (n = 15) and moderate (n = 15). Each grade is subdivided into three groups as Group A, Group B, and Group C. Group 1: Mild (score 2), Subgroup A: Resin infiltration (n = 5 patients), Subgroup B: Microabrasion followed by resin infiltration (n = 5 patients), Subgroup C: Microabrasion and bleaching followed by resin infiltration after 2 weeks (n = 5 patients). Group 2: Moderate (score 3), Subgroup A: Resin infiltration (n = 5 patients), Subgroup B: Microabrasion followed by resin infiltration (n = 5 patients), and Subgroup C: Microabrasion and bleaching followed by resin infiltration after 2 weeks (n = 5 patients). Microabrasion was performed with the opalustre kit from Ultradent according to the manufacturer's instructions. Pola office bleaching from SDI and Icon infiltrant was performed. Stain score, improvement in appearance score, need for further treatment, patient satisfaction score, tooth sensitivity immediately after treatment, 24 h and 72 h were recorded.

Results:

The mean appearance score in Group 1A was 73.60, in Group 1B was 72.87, in Group 1C was 65.27, in Group 2A was 68.00, in Group 2Bwas 72.93 and in Group 2C was 84.73. The mean need for further treatment score in Group 1A was 72.80, in Group 1B was 78.40, in Group 1C was 68.73, in Group 2A was 71.20, in Group 2B was 79.53 and in Group 2C was 88.73. The mean patient satisfaction score in Group 1A was 91.40, in Group 1B was 95.20, in Group 1C was 98.00, in Group 2A was 90.20, in Group 2B was 99.40 and in Group 2C was 100.00. There was a significant difference in mean tooth sensitivity immediately after treatment between Groups 1A, 1B, 1C, 2A, 2B, and 2C. There was a significant difference in mean tooth sensitivity after 24 h between Groups 1A, 1B, 1C, 2A, 2B, and 2C.

Conclusion:

Resin infiltration technique in combination with bleaching and microabrasion technique found to be effective in the management of dental fluorosis.

Erosion Infiltration in the Management of Molar-Incisor Hypomineralization (MIH) Defects

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.

Esthetic Management of Incisors with Diffuse and Demarcated Opacities: 24 Month Follow-up Case Report

CLINICAL RELEVANCE

A minimally invasive esthetic treatment can provide longevity and color stability.

SUMMARY

This clinical case report describes a minimally invasive approach to mask diffuse and demarcated opacities in permanent anterior teeth in an eight-year-old child who was upset with the appearance of her incisors. Clinical examination showed diffuse opacities in teeth 7, 8, 9, and 10, diagnosed as dental fluorosis associated with yellow demarcated opacity in tooth 9 related to molar-incisor hypomineralization. The treatment was based on conservative dentistry using the low-viscosity resin infiltration technique and resin composite restoration in an attempt to mask the lesions. The follow-up time was 24 months.

Color Masking White Fluorotic Spots by Resin Infiltration and Its Quantitation by Computerized Photographic Analysis: A 12-month Follow-up Study

OBJECTIVE

To manage three cases of mild to moderate fluorosis by resin infiltration technique and to quantify the tooth color changes by measuring CIE L*a*b* values of digital photographs and calculating ΔE₀₀ based on the CIEDE2000 formula using Adobe Photoshop software.

METHODS AND MATERIALS

Three cases of mild to moderate fluorosis were treated with a combination of bleaching and a resin infiltration technique. CIE L*a*b* values of 18 fluorosed spots were measured from digital photographs of these cases at four different stages-preoperative, postbleaching, postinfiltration and at 12-month follow-up-using Adobe Photoshop software, and ΔE₀₀ was calculated based on the CIEDE2000 formula. The ΔE₀₀ values of all 18 points obtained at different stages were submitted to statistical analysis (α=0.05).

RESULTS

In all the cases reported, clinically as well as by the photographic color analysis, it was found that the technique masked the lesions, improving the patients' esthetics, which was maintained even at 12-month recall. Statistically significant difference in ΔE₀₀ values was present between comparison of all stages (p<0.001) except between postinfiltration and the 12-month follow-up stage (p=0.642).

CONCLUSION

A resin infiltration technique helped in the satisfactory management of white spot lesions of fluorosis, which were stable even at 12-month follow up. Quantitation of the changes was achieved using Adobe Photoshop software.
