Summary

The aim of this work was to define the influence of orthodontic treatment with a fixed appliance on hard dental tissues. Etching of various surfaces of enamel in vitro with special reference to sites where the orthodontic appliance is bonded (pilot test), as well as etching in vivo of enamel in patients awaiting treatment with the fixed appliance was studied. The pilot test disclosed that enamel demineralization is easiest on tangential and paracervical buccal surfaces. Placement of a fixed appliance is associated with difficulties in maintaining hygiene of the oral cavity. Therefore, thorough cleaning of the aforementioned surfaces of the tooth is of great importance for prevention of caries and gingivitis.

It was demonstrated that laser fluorescence of enamel is affected by the process of etching. Laser fluorescence values of enamel increased after etching in each group. There was no effect of age on laser fluorescence of enamel before and after etching.

K e y w o r d s: enamel etching – orthodontic treatment.
