BASIC DIRECTIONS IN FLUOROSIS TREATMENT

Abstract

The territory of Poltava region belongs to the Buchatsky hydrogeological province, whose groundwater is characterized by an elevated fluorine level content. The cause of endemic dental fluorosis particularly in the children’s population of the region is water consumption with surplus concentration of this chemical element. Also, having fluorosis a condition that develops from a high fluoride concentration in drinking water- causes disorder of hard tooth tissues maturing, mineralizationand teeth germ development. This, in turn, has a negative influence on enamel amelogenin synthesis and violation of the crystals maturing, determines a surface porosity. The chalky spots, brown pigmentation, and enamel erosion destruction lesions are characterized the different severity manifestation of the fluorosis. The purpose of our research was to conduct a thorough analysis of all the material we found on this topic, gather all possible information on new trends in recent years in the treatment of dental fluorosis: what are the methods, their origins, indications for use, clinical stages and advantages. Dental enamel fluorosis requires different approaches to treatment depending on the severity of clinical manifestations. Obviously, as the leading method is remineralizing therapy. One of the method is offered by Nikolishina E.V. etc. [6], which is carried out in the following way: after carry out of the professional hygiene procedure, next step, individual caps were made of transparent silicone filled with 10% solution «Poltavsky Bishofit» and applied on the fluorosis teeth, daily course consist with 30 minutes and 10-20 procedures. Enamel microabrasion is the first minimally invasive treatment method of mild and moderate dental fluorosis using to removes opaque brown spots and surface roughness smoothing, providing a flat and shinier surface. The microabrasion technique involves etching with mild acid in combination with application of abrasive components. Resin infiltration has also become a popular treating dental fluorosis technique without loss of hard tissue. Resin infiltration is based on the application of hydrochloric acid to the hard tissues of the tooth and subsequent coating with a low-viscosity resin that penetrates into the microspaces of the tooth enamel. The cloaking effect is based on the refractive index. The optical properties of the affected enamel change and it looks like a healthy enamel surrounding. The indication to dental fluorosis treatment of severity forms in permanent teeth with mature roots is restoration of teeth, veneers, orthopedic crowns, if the microabrasive method hasn’t aesthetic effect efficiency. Thus, in cases of aesthetic changes due to fluorosis, minimally invasive restorative approaches that preserve dental hard tissue such as microabrasion method, external bleaching or resin infiltration should be considered before invasive restorative procedures. More invasive treatments may be considered if the results remain unsatisfactory.
