Abstract

Introduction. The most of dental practitioners have some doubts about teeth bleaching safety in patients with teeth abfractions and gingival recession. Aim. Assessment of professional oral debridement and teeth bleaching safety in patients with teeth abfractions and gingival recession. Material and methods. Randomized controlled trial was done in two groups of 30 patients with teeth abfractions and gingival recession. In group 1 oral debridement and professional dental bleaching were performed. Abfractions and recessions were isolated with a liquid dam. In group 2 oral debridement was made. The vertical size of recession, Tooth Wear Index and Schiff air sensitivity index were evaluated. Results. After 12 months the enlargement of wedge defects was pronounced in 5 teeth in group 1 and in 7 teeth in group 2. The enlargement of the gingival recession was marked in 6 teeth in group 1 and in 8 teeth in group 2. No statistical difference between groups was seen. In group 1 after teeth bleaching the sensitivity was present in 240 teeth (40%), after 14 days amount of teeth with sensitivity reduced to 110 (18.3%). In group 2 after oral debridement, the sensitivity was present in 250 teeth (41.7%), after 14 days amount of teeth with sensitivity reduced to 239 (39.8%). Conclusion. The teeth bleaching has no effect on dental abfractions and gingival recession.
