RESUMEN
La decoloración de las piezas dentarias puede te-ner un impacto estético y social que lleva a los pa-cientes a buscar una intervención para mejorar su sonrisa. Las manchas superficiales y las irregula-ridades del esmalte pueden deberse a hipoplasias, hipomineralización molar, fluorosis, uso de medica-mentos, manchas blancas causadas por traumatis-mos o infección en la dentición primaria, o manchas post ortodóncicas. El diagnóstico de los defectos del esmalte se realiza a través de un examen visual por transiluminación. Se han propuesto técnicas micro abrasivas con diferentes agentes para eliminar las manchas superficiales del esmalte, así también como el uso de agentes blanqueadores a baja concentra-ción para equilibrar el color de las piezas dentarias. Si las manchas son profundas se requiere de una mega abrasión y posterior restitución anatómica con resinas compuestas. Los avances tecnológicos en los materiales de restauración adhesivos permi-ten imitar las piezas dentarias naturales permitien-do la mínima destrucción de la estructura dental sin comprometer futuras opciones de restauración. El objetivo de este trabajo es mostrar una secuencia de procedimientos mínimamente invasivos para devol-ver la estética perdida en una paciente que concurre a la Cátedra de Odontología Restauradora (AU)
The discoloration of dental pieces can have an aesthetic and social impact that leads patients to seek an intervention to improve their smile. Superficial stains and enamel irregularities may be due to hypoplasia, molar hypomineralization, fluorosis, drug use, white spots caused by trauma or infection in the primary dentition, or post-orthodontic stains. The diagnosis of enamel defects is made through a visual examination by transillumination. Microabrasive techniques with different agents have been proposed to remove surface stains from the enamel, as well as the use of low-concentration whitening agents to balance the color of the teeth. If the stains are deep, a mega abrasion and subsequent anatomical restoration with composite resins are required. Technological advances in adhesive restorative materials make it possible to mimic natural teeth, allowing minimal destruction of tooth structure without compromising future restorative options. The objective of this work is to show the sequence of minimally invasive procedures to return the lost aesthetics in a patient who attends the Chair of Restorative Dentistry (AU)

This study aimed to evaluate the effect on oral health-related quality of life (OHRQoL) of two treatment protocols for dental fluorosis in individuals enrolled in a randomized clinical trial. Seventy volunteers, who lived in a fluorosis endemic area in Brazil, and had at least four maxillary anterior teeth showing fluorosis with a Thylstrup and Fejerskov index from 1 to 7, were randomized into two treatment groups (n= 35): GI- enamel microabrasion; or GII- microabrasion associated with at-home bleaching. Microabrasion was performed using 37% phosphoric acid and pumice, and at-home tooth bleaching with 10% carbamide peroxide in a tray. Volunteers completed a questionnaire at baseline and 1-month post treatment to assess changes in OHRQoL, using the Oral Impact on Daily Performance (OIDP). Differences in overall impact scores between and within treatment groups were analyzed with Wilcoxon (within) and Mann-Whitney (between) tests. Changes in performance scores were analyzed using Wilcoxon tests (a< 0.05). One month after treatment, subjects reported improvement in OHRQoL. Both groups showed lower OIDP scores (p< 0.001), but there was no difference between them. Eating, cleaning teeth, smiling and emotional state performance scores were lower after treatment for the whole sample. In conclusion, the treatment with microabrasion improved the OHRQoL in this sample of individuals living in a fluorosis endemic area regardless of the addition of at-home bleaching.

Resumo Este estudo teve como objetivo avaliar o efeito na qualidade de vida relacionada à saúde bucal (QVRSB) de dois protocolos de tratamento para fluorose dentária, em indivíduos incluídos em um ensaio clínico randomizado. Setenta voluntários, os quais viviam em uma área de fluorose endêmica no Brasil, e que possuíam pelo menos quatro dentes ântero-superiores com índice de Thylstrup e Fejerskov de 1 a 7, foram randomizados em dois grupos de tratamento (n= 35): GI- microabrasão de esmalte; ou GII- microabrasão associada com clareamento caseiro. A microabrasão foi realizada com ácido fosfórico 37% e pedra pomes e, o clareamento caseiro com peróxido de carbamida 10% e uso de moldeira. Os voluntários responderam um questionário antes e 1 mês após o tratamento, visando avaliar mudanças na QVRSB através do instrumento Oral Impact on Daily Performance (OIDP). Diferenças nos escores de impacto geral entre e nos mesmos grupos de tratamento foram analisadas através dos testes Wilcoxon (mesmo grupo) e Mann-Whitney (entre grupos), respectivamente. Alterações no escores dos domínios foram analisadas usando o teste Wilcoxon (a<0.05). Um mês após o tratamento, os indivíduos relataram melhora na QVRSB. Ambos os grupos apresentaram menores escores do OIDP (p<0,001), sem diferença entre eles. Os escores dos domínios comer, limpar os dentes, sorrir e estado emocioal diminuíram após o tratamento para toda a amostra. Concluiu-se que o tratamento com microabrasão melhorou a QVRSB de indivíduos vivendo em uma área de fluorose endêmica independentemente da associação com o clareamento caseiro.

A evolução de técnicas conservadoras contribui para uma melhora estética e a microabrasão do esmalte vem sendo pesquisada e indicada como tratamento para remoção de manchas superficiais do esmalte dentário. O objetivo deste estudo in vitro foi comparar através da análise por perfilometria digital 3D, a rugosidade superficial (Sa) do esmalte bovino microabrasionado com ácido fosfórico a 37% e pedra pomes (A) associado a três tipos de pontas aplicadoras: taça de borracha (T), ponta cônica (C) e opal cups (O). Para a análise de superfície foram selecionados 9 espécimes, previamente planificados e divididos em 3 grupos (AT; AC; AO) contendo 3 amostras cada. No presente experimento, optou-se por fazer 6 aplicações de 10 segundos, utilizando método de aplicação mecânico, com rotação do micromotor de 12.000rpm, sendo a carga atuante sobre os espécimes de 30g. Observou-se que para as três pontas houve diferença estatística significante entre a rugosidade superficial inicial (SaI AT = 0,023µm; AO = 0,026µm e AC = 0,026µm) e rugosidade superficial final (SaF AT = 0,384µm; AO = 0,442µm; AC = 0,305µm; Wilcoxon, p<0,05). Os menores valores de rugosidade superficial foram promovidos pela ponta cônica, seguidos por taça de borracha e Opal Cups.
The evolution of conservative techniques contributes to improve aesthetics. Enamel microabrasion has been researched and performed as a treatment to remove stains on enamel surface. The aim of this in vitro study was to compare surface roughness (Sa) of microabrasioned enamel with 37% phosphoric acid and pumice (A) associated with three types of applicator tips: cup rubber (T), conical tip (C) and opal cups (O). For surface analysis 9 specimens were selected, they were previously flattened and divided into 3 groups (AT, AC, AO) with 3 samples each. In this experiment, 6 applications of 10 seconds were performed using mechanical rotation of 12.000 rpm under 30g acting load on the samples. Statistically significant difference between the initial surface roughness was observed for the three tips: (SaI AT = 0.023 µm; AO = 0.026 µm and AC = 0.026 µm) and final surface roughness (SaF AT = 0.384 µm; AO = 0.442 µm; AC = 0.305 µm; Wilcoxon, p <.05). The lower surface roughness values were promoted by tapered tip, followed by rubber and Opal Cups.

OBJECTIVE: To determine by means of a systematic review the best treatment, whether interproximal wear or incisor extraction, to correct anterior lower crowding in Class I patients in permanent dentition. METHODS: A literature review was conducted using MEDLINE, Scopus and Web of Science to retrieve studies published between January 1950 and October 2013. In selecting the sample, the following inclusion criteria were applied: studies involving interproximal wear and/or extraction of mandibular incisors, as well as Class I cases with anterior lower crowding in permanent dentition. RESULTS: Out of a total of 943 articles found after excluding duplicates, 925 were excluded after abstract analysis. After full articles were read, 13 were excluded by the eligibility criteria and one due to methodological quality; therefore, only fours articles remained: two retrospective and two randomized prospective studies. Data were collected, analyzed and organized in tables. CONCLUSION: Both interproximal wear and mandibular incisor extraction are effective in treating Class I malocclusion in permanent dentition with moderate anterior lower crowding and pleasant facial profile. There is scant evidence to determine the best treatment option for each case. Clinical decision should be made on an individual basis by taking into account dental characteristics, crowding, dental and oral health, patient's expectations and the use of set-up models.

Enamel microabrasion is an efficient method for treating fluorosis since it is a controlled non-invasive technique to remove surface stains promoting a minimum wear of the tooth structure. This paper aimed to report a case of stains removal on the upper incisors using the microabrasion technique. After detailed history taking, clinical examination and confirmation of the diagnosis of dental fluorosis, it was used a paste at 1:1 proportion of 37% phosphoric acid and pumice stone on the surface of the affected teeth. This technique can be used to re¬cover aesthetics of permanent teeth in children presenting opaque patches suggestive of fluorosis, being well accepted by the patient for being a conservative technique, easy to perform and fast, while presenting immediate aesthetic result that motivates the patient immediately.
Para o tratamento da fluorose dentária, a microabrasão do esmalte é um eficiente método para remover manchas superficiais, por consistir em uma técnica controlada e não invasiva promovendo uma quantidade mínima de desgaste da estrutura dentária. Este trabalho tem como objetivo relatar um caso clínico de remoção dessas manchas nos incisivos permanentes superiores utilizando a técnica de microabrasão. Após anamnese e exame clínico minucioso e confirmação do diagnóstico de fluorose dentária, foi empregada uma pasta de ácido fosfórico a 37% e pedra pomes numa proporção de 1:1 com ponta abrasiva na superfície dos dentes afetados. Esta técnica de microabrasão pode ser utilizada para a recuperação estética de dentes permanentes em crianças que apresentam manchas opacas sugestivas de fluorose, sendo bem aceita pelo paciente infantil por ser uma técnica conservadora, de fácil execução e rápida, além de apresentar um resultado estético imediato que motiva o paciente.

Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface. Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections. This article presented and discussed the indications and limitations of enamel microabrasion treatment. Three case reports treated by enamel microabrasion were also presented after 11, 20 and 23 years of follow-ups.

BACKGROUND: Endemic dental fluorosis has already been described in some regions of the world. The aim of this study was to evaluate the functional and psychosocial impact of direct aesthetic restorative treatments in endemic fluorosis patients in the northern state of Minas Gerais, Brazil. Was a quasi-experimental intervention study. METHODS: The reference population consisted of individuals between 9 and 27 years of age that were served by a project intended to recover the smiles of patients with severe fluorosis. The questionnaires were administered on two occasions, 24 months apart (before and after dental treatment). Initially, descriptive analyses were conducted. Prevalence and severity, as well as the extent of the functional and psychosocial impact of oral disorders were estimated based on the Oral Health Impact Profile instrument (OHIP-14). Comparisons between baseline and follow-up and between treatment techniques were carried out using the McNemar, Wilcoxon, and Mann-Whitney tests. RESULTS: The study involved 53 individuals, with a mean age of 15.9 years, treated with microabrasion, dental composite, or a combination of both techniques. The treatments performed proved to be competent for reducing the functional and psychosocial impact of oral disorders as measured by the OHIP-14, pointing to the possibility of establishing protocols to be used in programs aimed at restoring the aesthetics and functionality of the anterior teeth in large populations. CONCLUSIONS: After performing the direct aesthetic restorative treatments in patients with endemic fluorosis, a significant improvement was observed in the prevalence and severity, as well as the extent of the functional and psychosocial impact of oral disorders.

A fluorose dental é causada pela exposição do germe dental, em sua fase de formação, a altas concentrações de flúor. A preocupação com a estética do sorriso tem acarretado transtornos para os indivíduos que possuem estas alterações, portanto, o tratamento é indicado quando a autoestima do paciente é afetada. Para esses casos, tratamentos minimamente invasivos, como a microabrasão e o clareamento dental, até tratamentos menos conservadores, como a confecção de restaurações, coroas protéticas e facetas, podem ser indicados. O objetivo deste relato de caso foi demonstrar o procedimento de microabrasão associado ao clareamento dental caseiro com peróxido de carbamida 10% em um paciente com fluorose, minimizando as alterações cromáticas que comprometiam a estética dental. Para isso foram realizadas duas sessões de microabrasão em esmalte, seguidas do clareamento caseiro por um período de três horas diárias três semanas. Após o desenvolvimento das duas técnicas, pôde-se concluir que ambas foram efetivas, obtendo um resultado estético favorável e aprovado pelo paciente.
Dental fluorosis is caused by the exposure of tooth germ, in formative stage, to high concentrations of fluoride. The concern with the aesthetics of the smile has led to disorders in individuals who have these changes, so treatment is indicated when the patients self-esteem is affected. In these cases minimally invasive treatments such as microabrasion and dental bleaching, as well as less conservative treatments, such as restorations, prosthetic crowns and veneers may be indicated. The aim of this case report was to demonstrate microabrasion associated with home bleaching using 10% carbamide peroxide in a patient with fluorosis, minimizing chromatic alterations that compromise dental aesthetics. Thereunto were conducted two sessions of enamel microabrasion followed by home bleaching in a period of three hours a day for three weeks. After the development of the two techniques, it was concluded that both were effective, obtaining a favorable aesthetic result approved by the patient

OBJECTIVES: This parallel randomized clinical trial evaluated the efficacy of two treatments for removing fluorosis stains. METHODS: Seventy individuals living in an area endemic for fluorosis, with at least four maxillary anterior teeth presenting fluorosis with a Thylstrup and Fejerskov index from 1 to 7, were randomized into two treatment groups (n=35): GI - enamel microabrasion or GII - microabrasion associated with at-home bleaching. Microabrasion was performed using 37% phosphoric acid and pumice and, at-home tooth bleaching was performed with 10% carbamide peroxide. Areas of enamel opacities were recorded by digital camera at baseline and 1-month (1M) after treatment. Two blinded examiners evaluated the reduction in the area (mm(2)) of opacity using software. Two visual analogue scales were used: one for recording tooth sensitivity and/or gingival irritation ranging from 1 (none) to 5 (severe) and the other to evaluate participant satisfaction with the treatment used ranging from 1 (no improvement) to 7 (exceptional improvement). RESULTS: 1M after treatment, both groups showed a significant reduction in the area of enamel opacity (p=0.0001) and there was no difference between groups (p=0.1). Most of the participants from both treatment groups reported no or mild tooth sensitivity and gingival irritation (p>0.05). Participants reported that they were happy with the improvement in dental appearance, however, individuals from GII reported that they were happier than those from GI (p=0.004). CONCLUSIONS: Both treatment protocols were effective in reducing fluoride stains, however, when home bleaching was associated to enamel microabrasion, patients reported a major satisfaction with dental appearance.

OBJECTIVE: To evaluate the in vitro changes on the enamel surface after a micro-abrasion treatment promoted by different products. MATERIAL AND METHODS: Fifty (50) fragments of bovine enamel (15 mm × 5 mm) were randomly assigned to five groups (n=10) according to the product utilized: G1 (control)= silicone polisher (TDV), G2= 37% phosphoric acid (3M/ESPE) + pumice stone (SS White), G3= Micropol (DMC Equipment), G4= Opalustre (Ultradent) and G5= Whiteness RM (FGM Dental Products). Roughness and wear were the responsible variables used to analyze these surfaces in four stages: baseline, 60 s and 120 s after the micro-abrasion and after polishing, using a Hommel Tester T1000 device. After the tests, a normal distribution of data was verified, with repeated ANOVA analyses (p≤0.05) which were used to compare each product in different stages. One-way ANOVA and Tukey tests were applied for individual comparisons between the products in each stage (p≤0.05). RESULTS: Means and standard deviations of roughness and wear (µm) after all the promoted stages were: G1=7.26(1.81)/13.16(2.67), G2=2.02(0.62)/37.44(3.33), G3=1.81(0.91)/34.93(6.92), G4=1.92(0.29)/38.42(0.65) and G5=1.98(0.53)/33.45(2.66). At 60 seconds, all products tended to produce less surface roughness with a variable gradual decrease over time. After polishing, there were no statistically significant differences between the groups, except for G1. Independent of the product utilized, the enamel wear occurred after the micro-abrasion. CONCLUSIONS: In this in vitro study, enamel micro-abrasion presented itself as a conservative approach, regardless of the type of the paste compound utilized. These products promoted minor roughness alterations and minimal wear. The use of phosphoric acid and pumice stone showed similar results to commercial products for the micro-abrasion with regard to the surface roughness and wear.

The use of phosphoric acid and pumice stone showed similar results to commercial products for the micro-abrasion with regard to the surface roughness and wear. .

This article describes a minimally invasive technique for removal of intrinsic enamel stains and discoloration. The technique is based on enamel microabrasion with application of an acid-abrasive gel. Treatment may be complemented with composite resin to compensate for the effects of acid or to finish the masking effect.

Enamel white spot lesions in anterior teeth that compromise esthetics are common. Microabrasion is indicated, since it affects enamel superficially. An acid-abrasive slurry with 37% phosphoric acid with pumice was used on the enamel for a controlled time period. Home bleaching with hydrogen peroxide was then used, further improving the final result. The method is safe, easy, and conservative and provides good esthetic results.
