RESUMO

Dental fluorosis is the most common and prominent symptom in the early stage of chronic fluorosis, which is caused by excessive fluorine intake during tooth development. In severe cases, it may be accompanied by skeletal fluorosis. There are also systemic damages to the nervous system, cardiovascular system, endocrine system and so on. The pathogenesis of dental fluorosis is not totally clear, which may be a complex pathological process involving both genetic and environmental factors. The prevalence of dental fluorosis has an upward trend arround the world, thus certain public prevention and treatment strategies need to be taken. This article focuses on the prevalence, etiology, diagnosis and scoring system, as well as the public prevention and treatment strategies, of dental fluorosis, so that to provide reference for the research and prevention of the disease.

RESUMO

La odontología de mínima invasión se ha convertido en la filosofía de tratamiento dental más aceptada en la actualidad. La posibilidad de incorporarla se ha debido en gran medida a la aparición de nuevos materiales dentales que se adhieren a la estructura dental, a técnicas más conservadoras de estructura dental sana y sobre todo a una nueva forma de pensar tanto de clínicos como de los mismos pacientes. La odontología estética contemporánea se ha visto infl uenciada por este nuevo paradigma. El tratamiento de pigmentaciones dentales también se ha visto benefi ciado por esta nueva tendencia y nuevos materiales han aparecido recientemente que conservan la mayor cantidad de tejido dental sano sin necesidad de preparaciones no conservadoras. Lo más importante al incorporar estas nuevas tecnologías es la realización de un diagnóstico adecuado entendiendo la causa que origina esta condición y así poder implementar el mejor tratamiento posible (AU)


Minimally invasive dentistry has become the standard of care most widely accepted today. This trend has been posible in great extent to the advent of new dental materials that adhere to dental structure, more conservative techniques of healthy dental tissue but mainly from clinicians and patients with a new way of thinking. Contemporary esthetic dentistry has been influenced by this new paradigm. Treatment of dental stainings has also been infl uenced by this new trend and new materials have recently surfaced that keep healthy dental tissue without the need of non conservative preparations. The most important aspect in order to incorporate this new technologies is a correct diagnosis understanding the cause that originated this condition in order to implement the best posible treatment (AU)

RESUMO

PURPOSE: To evaluate the clinical performance of at-home bleaching and its application in combination with cold-light bleaching for esthetic management of fluorosed teeth,providing guidance for clinicians to choose the right treatment regimen and communicate with patients successfully. METHODS: We divided 43 cases with stained dental fluorosis into 2 groups, with 22 cases in the at-home bleaching group and 21 in the combination therapy group. Stained spots were chosen and colorimetric assay was performed using CMYK colorimetric table before treatment. According to the color of the splash, the light and shade were divided into light grade, medium grade and heavy grade. The CMYK data of the selected point and complete decolorization ratio (stain decolorization rate) were recorded after cold-light bleaching, every 2 weeks and half a year later. Meanwhile, tooth sensitivity was recorded using visual analogue scale (VAS). Statistical analysis was performed using SPSS 17.0 software package. RESULTS: In the combination therapy group, the decolorization rates of light, medium and heavy stains were 73.44%, 8.70% and 0% immediately after cold-light bleaching respectively. At 2 weeks, in the at-home group, the postoperative decoloring rate was 64.17% in the light grade group and 4.44% in the medium grade group, respectively. In the combination therapy group, the postoperative decoloring rate was 100% in the light grade group and 63.04% in the medium grade group, respectively (P<0.01). The postoperative decoloring rate in the heavy grade group was 0%. At 4 weeks, in the at-home group, the postoperative decoloring rate was 100% in the light grade group, 73.33% in the medium grade group and 11.40% in the heavy grade group, respectively. In the combination therapy group, the postoperative decoloring rate was 100% in the medium grade group and 53.00% in the heavy grade group, respectively (P<0.01). At 6 weeks, in the at-home group, the postoperative decoloring rate was 100% in the medium grade group and 76.32% in the heavy grade group. In the combination therapy group, the postoperative decoloring rate was 94.00% in the heavy grade group (P<0.01). At 8 weeks, the postoperative decoloring rate was 95.61% in the heavy grade group of at-home group. Half a year after treatment, bleaching decoloration rate had no significant difference compared with that at the end of treatment (P>0.05). Tooth sensitivity was 45.45% in the at-home group and 80.95% in the combination therapy group (P<0.05). CONCLUSIONS: Fluorosed teeth show significantly better esthetic appearance after both the at-home bleaching and the combination therapy at 6-8 weeks, and can maintain stable for a long time. Cold-bleaching has faster decoloration speed, with the final decolorization rate of the stains unchanged. In addition, it increases the incidence of postoperative sensitivity of teeth.

RESUMO

Dental fluorosis is a condition that produces unesthetic coloration of enamel because of excessive fluoride ingestion during enamel formation. Its appearance can range in severity from mildly white and opaque to dark brown and can lead a patient to seek dental treatment. Historically, these lesions have been masked, either with direct or indirect restorations, but more conservative treatment options are now available, including the combination of microabrasion and bleaching. This clinical report describes the use of these treatment options to address a young patient's dental fluorosis.

RESUMO

The objectives were to evaluate the efficacy of a filled adhesive named Prime & Bond NT (P&B NT) as the dentin desensitizer in occluding fluorosis dentinal tubules and compare the shear bond strength (SBS) of RelyX U200 self-adhesive resin cement (RXU) and RelyX Luting self-adhesive resin-modified glass ionomer cement (RMGIC) before and after P&B NT pretreatment. 176 non-carious fluorosis were classified into four subgroups by the Thylstrup and Fejerskov index (TFI): normal group (TFI = 0), mild group (TFI = 1-3), moderate group (TFI = 4-5), severe group (TFI = 6-9). 160 composite cylinders (4 × 5 mm) were fabricated, then every severity of fluorosed dentin was subjected to four treatments: P&B NT + RXU (n = 40), RXU (n = 40), P&B NT + RMGIC (n = 40), RMGIC (n = 40). The specimens were immersed in water at 37°C for 24 hr first and half of them underwent 5,000 thermocycling before shear bond strength test. A factorial design (factorial 4 × 2 × 2 × 2) was developed to make statistical analysis. Scanning electron microscope (SEM) analysis (n = 16) in cross section and longitudinal section view characterized the occlusion situation of dentinal tubules. P&B NT might occlude dentinal tubules as the dentin desensitizer for normal teeth and mild-moderate fluorosis. P&B NT significantly increased the SBS of RXU (p < .05) but had no statistical significance on the SBS of RMGIC (p > .05). RXU could benefit from P&B NT desensitization to achieve a better quality of adhesion.

RESUMO

The aim of the study was to assess the mineral composition of mixed saliva in dental fluorosis patients undergoing treatment with microabrasion and bleaching. The study included 60 patients aged 18-35 years with various forms of dental fluorosis. Group 1 included 40 patients in which enamel microabrasion was performed, group 2 - 20 patients with microabrasion and bleaching. Mixed saliva composition was analyzed with Olimpus automatic analyzing device. Dental fluorosis treatment in both groups resulted in saliva mineral composition changed associated with enamel demineralization which proves the necessity for calcium and phosphate containing compositions in these treatment groups.

RESUMO

Enamel microabrasion is a noninvasive method that removes intrinsic and superficial defects from teeth aimed to improve dental esthetic with minimal loss of dental tissue. This case presentation describes the attempt for teeth color correction utilizing that conservative technique in a young girl whose maxillary anterior teeth presented an opaque white/brown stain. Along with microabrasion, an innovative approach of application of casein phosphopeptide-amorphous calcium phosphate crème on the tooth, and remineralization was carried out thereby reducing postoperative sensitivity of the treated tooth. Based on the results of this case report, it can be concluded that this technique is efficient and can be considered a minimally invasive procedure.

RESUMO

CONTEXT: Dental fluorosis is caused by successive exposure to high concentrations of fluoride during tooth development leading to enamel with lower mineral content and increased porosity. AIMS: The aim of the study was to evaluate and compare the effectiveness of minimally invasive techniques for the removal of dental fluorosis stains in children in vivo. DESIGN: Ninety children in the age group of 10-17 years were selected. MATERIALS AND METHODS: The study sample was equally and randomly divided into three groups; Group 1: In-office bleaching with 35% hydrogen peroxide (HP) activated by light-emitting diode (LED) bleaching unit (35% HP), Group 2: Enamel microabrasion (EM) followed by in-office bleaching with 44% carbamide peroxide gel (EM), Group 3: In-office bleaching with 5% sodium hypochlorite (5% NaOCl). Statistical analysis was done using one-way ANOVA test. RESULTS: Bleaching with 35% HP activated by LED bleaching unit and EM followed by bleaching with 44% carbamide peroxide were equally effective for the removal of dental fluorosis stains in children in vivo. However, bleaching with 5% NaOCl could not completely remove moderate to severe stains. It was effective in removing only mild stains. Bleaching and microabrasion procedures caused slight decrease in tooth sensitivity readings by electric pulp vitality tester which continued to increase over time. However, none of the patients reported sensitivity in their teeth at any point of time. Patients were highly satisfied with the treatment outcome postoperatively but reported slight relapse of color in the three groups. CONCLUSIONS: Bleaching and microabrasion techniques can consider as an interesting alternatives to conventional operative treatment options.

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.

RESUMO

Different approaches ranging from veneers and crowns to employing the more conservative use of freehand resin composites have been proposed to correct esthetic problems caused by enamel fluorosis (EF). However, the protocol of mega-abrasion followed by microabrasion may be used as an alternative. It is less invasive and can minimize the unesthetic brown-to-whitish spots caused by EF. This article describes an easy and low-cost technique for managing enamel defects in a patient with severe enamel fluorosis.

RESUMO

This clinical report illustrates a conservative technique to mask enamel discolorations in maxillary anterior teeth caused by hypomineralization associated with enamel fluorosis and subsequent direct resin composite to improve the anterior esthetics. The treatment consisted of at-home whitening with 10% carbamide peroxide gel with potassium nitrate and sodium fluoride in a custom-fitted tray to mask the brown-stained areas, followed by resin infiltration to mask the white spot areas. An existing resin composite restoration in the maxillary right central incisor was subsequently replaced after completion of the whitening and resin infiltration procedures, whereas the two misaligned and rotated maxillary lateral incisors were built up with direct resin composite restorations to provide the illusion of adequate arch alignment, as the patient was unable to use orthodontic therapy.

RESUMO

OBJECTIVES: Dental fluorosis leads to esthetic deviation and varies from nonpitted white opacities, dark brown stains to pitting or structural breakdown of enamel surface. Treatment for fluorosis depends on the severity of condition and includes both noninvasive methods and invasive methods. Recently resin infiltration has been proposed as an alternative treatment for nonpitted fluorosis. This study was done to evaluate the esthetic changes in nonpitted fluorosis stains when treated with resin infiltration, in-office bleaching and combination therapies. MATERIALS AND METHODS: The present study is a randomized, single blinded controlled trial with four parallel arms with 1:1 allocation ratio. The intervention arms included bleaching with 35% hydrogen peroxide, resin infiltration, resin infiltration with increased infiltration time and a combination approach of bleaching and infiltration. Immediate esthetic changes were evaluated for two parameters including, 'Change in esthetics' and 'Improvement in opacities/stains' using a VAS scale by two independent observers. Kruskal-Wallis test and Mann-Whitney U-test were done for intergroup comparisons. RESULTS: Best results for both the parameters were observed among patients treated with resin infiltration with increased infiltration time. Mann-Whitney U test revealed significantly better results for resin infiltration groups (alone or combination with bleaching) as compared to bleaching alone (P < .001). CONCLUSIONS: Resin infiltration procedure with tailored etching times and increased infiltration time exhibited best results in terms of change in esthetics and improvement in stains. CLINICAL SIGNIFICANCE: White and brown opacities due to fluorosis have always been a concern for esthetics. In our study, resin infiltration technique with tailored etching times and increased infiltration time exhibited best immediate esthetic improvement for nonpitted fluorotic opacities and stains. These esthetic outcomes reaffirm the applicability of RI technique for nonpitted fluorosis, which was originally advocated only for white spot lesions due to early caries. This will in turn help the dentists to plan the esthetic management of nonpitted fluorosis in a micro-invasive manner.

RESUMO

AIM: Capillarity theory predicts that the pore volume infiltrated by a liquid in a body with tubular capillaries is directly proportional to the capillary radius. The expected volume available for infiltration is the loosely bound water volume, which can be related to the capillary radii. We tested the hypothesis that the proportion of the pore volume infiltrated by resin infiltrant (Vratioresin) is correlated and agrees with the proportion of the pore volume with loosely bound water ( [Formula: see text] ). DESIGN: Seven human fluorotic third molars (4 unerupted and 3 erupted; TF scores 4 to 7; fluoride content of inner coronal dentin ranged from 143 to 934µg Fluoride/g) were prepared and resin infiltration was performed during 10min in fluorotic enamel ground sections. Penetration depths were measured (polarizing microscopy and CLSM) and mineral volume and non-mineral volumes were measured at histological points (n=92) along transversal lines traced from the enamel surface to the enamel-dentin junction. RESULTS: No well-mineralized surface layer was found. Infiltration depths ranged from 250µm to 900µm. Vratioresin ranged from 1.8 to 17.7% (mean of 10.13%±4.1%), was lower than [Formula: see text] (p<0.00001 Hedge's g=1.51, 95% CI: 1.18/1.83), and correlated positively with [Formula: see text] (R=0.684; 95% CI: 0.557/0.780) and negatively with the air volume remained after infiltration (R=-0.79; 95% CI: -0.698/-0.780). [Formula: see text] exceeded Vratioresin in 5% (1/4 of [Formula: see text] ) on average. CONCLUSION: [Formula: see text] and Vratioresin correlated well, but lacked good agreement. Organic matter, firmly bound water and air remained in enamel pores after resin infiltration.

RESUMO

OBJECTIVE: To evaluate caries prevalence and dental treatment needs in Portuguese children and teenagers, as well as fluorosis prevalence in 12-year-old children, in order to address public oral health program strategies. PARTICIPANTS: A representative stratified random cluster sample of 3,710 participants of 6, 12, and 18 years old was selected. A questionnaire was applied to determine sociodemographic data and some oral health determinants. The clinical examination was based on the ICDAS criteria, then adapted to DMFS index, and Dean's index for fluorosis. RESULTS: Caries prevalence at 6, 12, and 18 years old was 45.2%, 47.0%, and 67.6%, respectively. D5MFT scores were 1.18 (SD 0.06) and 2.51 (SD 0.10), respectively. Treatment needs at 12 and 18 years old were associated with 0.37 (SD 0.03) and 0.75 (SD 0.06) values in the "decayed" (D5) variable. SiC index at 12 years old was 2.68 (SD 1.68). Sealants were identified in 55% of 12-year-old children and the mean of sealants per individual was 3.61; also, moderate (2.2%) and severe (0.2%) levels of fluorosis were detected. CONCLUSIONS: The oral health situation in Portugal is favorable for young people, resulting in low treatment needs. The National Oral Health Promotion Program should be extended to include 18-year-olds.

RESUMO

Dental fluorosis results from excess fluoride ingestion during tooth formation and is commonly seen in certain endemic areas. Its clinical manifestations may range from white opaque patches of enamel in mild cases to pitting and loss of enamel in severe cases. The treatment of fluorosis is important not only because of esthetic and functional concerns but also to help improve a patient's self-esteem; therefore, a multidisciplinary approach is often necessary. This article describes a multidisciplinary approach to complete-mouth rehabilitation of a patient affected with fluorosis. A confluence of the endodontic, periodontal, orthodontic, and prosthodontic disciplines resulted in improved esthetics and enhanced masticatory efficiency.

RESUMO

The aim of this study was to report a clinical case of moderate fluorosis spots treated with infiltration of low-viscosity resin. A commercial resin was applied to the facial surfaces on the anterior teeth in both the maxillary and mandibular arches. The white spots of fluorosis lost their whitish appearance and appeared similar to sound enamel. This technique, which might constitute an alternative to white-masking of fluorosis spots, showed optimal esthetic results.

RESUMO

PURPOSE: To evaluate the effect of fluoride removal agent and microabrasion technology in LED teeth whitening of dental fluorosis. METHODS: One hundred and twelve patients with moderate dental fluorosis treated from August 2012 to July 2015 were divided into experimental group and control group according to random number table, with 61 cases in each group. In addition to pretreatment for all patients, patients in the control group were given combined treatment of Beyond LED whitening and fluoride removal agent; while patients in the experimental group were given microabrasion before LED whitening, with the same subsequent treatment process as that in the control group. The whitening effect and tooth sensitivity during whitening were compared between the two groups at the completion of treatment, 1 month and 6 months after treatment. SPSS 19.0 software package was employed for statistical analysis. RESULTS: There were no ineffective or lost patients in 2 groups. The effective rate of whitening for patients in the experimental group at completion of treatment, 1 month and 6 months after treatment was significantly higher than that in the control group (P<0.05). There was no case with tooth sensitivity during treatment. There was no significant difference in non-significant sensitivity rate or significant sensitivity rate between the 2 groups (P>0.05). CONCLUSIONS: Combined treatment with fluoride removal agent and microabrasion technology in LED teeth whitening for dental fluorosis can significantly improve the whitening effect and will not interfered by significantly increased tooth sensitivity.

RESUMO

In recent times, as a result of extensive drinking water fluoridation, the number of patients affected by fluorosis has increased considerably. The purpose of this clinical report is to describe the use of enamel microabrasion for a patient with severe fluorosis using 37% phosphoric acid and pumice mixture. The results were pleasing, and hence 37% phosphoric acid can be recommended as a safe and easily available alternative in microabrasion procedures.

RESUMO

Dental fluorosis manifests by too much ingestion of fluoride resulting in disturbances in enamel mineralization. The result is intrinsic discolorations in the maxillary and mandibular teeth with a poor esthetic appearance. In challenging cases, an esthetic result may be achieved only by a combination of techniques. This case report demonstrates a combination of modalities used to treat a patient presenting with atypical staining as a result of high-level exposure to ingested fluoride present in the drinking water as a child. Conservative treatment consisted of a combination of in-office bleaching to reduce the discoloration and porcelain veneers to create an esthetic result.
