Between each application, the enamel submitted to this technique should be washed and dried. Uma conquista promissora no campo da odontologia estética. Researchers demonstrated their findings in the case of a 29-year-old woman with a gummy smile and an unresolved endodontic lesion toward the root of the upper left central incisor. It is important to apply fluoride gel onto the tooth following the treatment, to brush well and to use the mousse cream. Esthetics plays an important role in contemporary dentistry, especially because the media emphasizes beauty and health.
A brief review of laboratory and clinical studies about microabrasion is also presented. Regression analysis revealed enamel loss of 12 microns after the initial application, and an average of 26 microns of enamel loss after each successive application. Advertisement Philips Zoom WhiteSpeed When it comes to lasting results and efficacy, Zoom WhiteSpeed outshines the competition. The procedure usually takes only about an hour and is permanent. It is important to protect the patient's, assistant's, and professional's eyes during this procedure. Enamel microabrasion is an esthetic treatment for removing superficial stains or defects of enamel. Sonicare FlexCare Platinum — more innovation, less plaque between teeth.
Currently, in many countries, a smile is considered beautiful if it imitates a natural appearance, with clear, well-aligned teeth and defined anatomical shapes. The color alterations were removed, the enamel surface of the maxillary right central incisor was evened, and the superficial layer of composite resin on the buccal aspect of the maxillary left central incisor was smoothed with a fine-tapered diamond bur, No. It is important to mention that macroabrasion with a fine grit tapered diamond bur can be used to reduce the time needed for the enamel microabrasion technique ,,. A 2% neutral-Ph sodium fluoride gel was applied for 4 minutes. The maxillary premolars also had facial decalcification spots.
The process is quick and easy, meaning you can have it done with one visit to our office. This technique has been elucidated and strongly advocated by Croll and Cavanaugh since 1986, 4 and by other investigators 1,2,5-13 who suggested mechanical removal of enamel stains using acidic substances in conjunction with abrasive agents. Although aesthetic demands for perfect smiles are increasing, economic problems have also influenced the patients' decisions among the treatment options. Dental bleaching with carbamide peroxide or hydrogen peroxide after enamel microabrasion has been suggested for some patients, since the enamel microabrasion promotes microreduction of the enamel surface ,,,. Enamel microabrasion is not indicated if the patient presents deficient lip sealing, as the teeth are always exposed to air and dehydrate more easily, thus a moistened film is not formed under the enamel.
But in cases where clinicians are unsure of the best method for improving tooth appearance, nothing is risked by first attempting enamel microabrasion. Enamel microabrasion for removal of smooth surface decalcification lesions. He can be reached at This email address is being protected from spambots. The second case study focuses on a 16-year-old boy who underwent enamel microabrasion to correct flaws in the gingival half of six upper front teeth. Surface enamel alterations that result from microabrasion, such as roughness and microhardness, are easily restored by saliva. The authors drew attention to the thickness of the enamel, particularly at the cervical third of the tooth, which is thinner compared to the medium and incisal third.
Polishing with fluoride paste, following the completion of enamel microabrasion. Aims and objectives: The aim of this study was to assess the efficacy of 18% hydrochloric acid and 37% phosphoric acid by an in vivo comparison. Briefly, enamel discolorations result from hypermineralization, hypomineralization, or staining. Another study 5 using polarized light microscopy demonstrated that a surface submitted to microabrasion tends to show higher resistance to demineralization and protects the teeth from Streptococcus mutans colonization. The effects of microabrasion on demineralization inhibition of enamel surfaces. A: Hypoplasia; B: Ineffective microabrasion treatment of the right central incisor.
Esthetic alterations such as fluorosis that result from intrinsic dental staining in enamel and dentin can be controlled or softened by noninvasive methods such as dental bleaching or enamel microabrasion. A considerable margin of clinical success has been shown when diligence to at-home protocols is achieved by the patient and supervised by the professional. More conservative approaches based on cheaper and less time-consuming treatments such as bleaching, micro-abrasive treatments and composite resin restorations are widely used. The results show distinct evidence of enamel surface changes that have been described as the abrosion effect. In patients who have deficient lip sealing a clinical condition that excessively hinders the formation of a moisturizing pellicle on the enamel, when unprotected by the upper and lower lips , enamel microabrasion can be delayed or contraindicated, because the enamel surfaces are abnormally dry, which makes demineralization stains more apparent.
