22/24. The aesthetic management of severe dental fluorosis in the young patient. The prevalence of dental fluorosis appears to be on the increase. Although in its mild form the condition is not considered to be of cosmetic significance, the more severe forms can cause great psychological distress to the affected individual. This article discusses the prevalence and mechanisms of dental fluorosis, and the aesthetic management of severe fluorosis in the young patient. ( info) |
23/24. The effectiveness of a modified hydrochloric acid-quartz-pumice abrasion technique on fluorosis stains: a case report. Endemic dental fluorosis is a form of enamel hypoplasia characterized by moderate-to-severe staining of the tooth surface. Since 1916, numerous investigators have used hydrochloric acid alone on fluorosis stains. More recently, 18% hydrochloric acid-pumice microabrasion has been used to achieve color modification. The main disadvantage of this procedure is the high concentration and low viscosity of hydrochloric acid, which can cause damage to oral and dental tissues. To eliminate this problem, quartz particles can be mixed with the hydrochloric acid. The quartz particles prevent the hydrochloric acid from flowing uncontrollablely by altering it to a gel-like form. A modified 18% hydrochloric acid-quartz-pumice abrasion technique was used to remove fluorine stains from vital teeth in a teenager. ( info) |
24/24. A successful combination of conflicting approaches to diastema closure--a case report. The closure of anterior maxillary diastemas can be accomplished in several ways. A case is reported where treatment initially consisted of the provision of porcelain laminate veneer restorations, with an unsatisfactory result. Subsequently, the restorations were reduced drastically in width and reshaped. The tooth widths were calculated from tables of mean measurements. The spaces were closed by orthodontic treatment and the original restorations were retained, saving the patient considerable treatment. ( info) |
