Abstract

Aim: To determine the effects of ultrasonic instrumentation on enamel and cementum of treated premolars.
Material and method: 20 impact premolars were treated in vitro. After extraction, the teeth are kept in phosphate buffer solution pH 7,0. Distal side of the teeth (3 mm over and under ECJ) was treated with ultrasonic instrumentation. (KAVO, SONIC flex 2000; frequency 6000 Hz). After 48 hours, samples were examined by SEM microscope (VEGA3LMU). Samples were examined with magnification 17 x to 300x.
Results: Number of fissures in 1 mm2 of enamel varies in the range of 28.35 ± 6.56 fissures; ± 95.00% KI: 25.28-31.42; and in 1mm2 of cement varies in the range of 151.90 ± 16.82 ; ± 95.00% KI: 144.03 - 159.77; The widest fissure varies in enamel in the range 6.78 ± 1.69 µm .; ± 95.00% KI: 5.99 - 7.57; the minimum is 2.85 µm. and the maximum value is 9.26 µm, and in cement varies in the range of 20.62 ±
6.83µm .; ± 95.00% KI: 17.42 - 23.81; the minimum is 9.26 µm and the maximum value is 38.36 µm. The narrowest fissure in enamel varies in the interval 5.99 ± 1.41 µm; ± 95.00% KI: 5.34-6.66; the minimum is 2.68 µm and the maximum value is 8.64µm, and in cement varies in the interval 17.25 ± 4.15 µm .; ± 95.00% KI: 15.31-19.19; the minimum is 7.62 µm. and the maximum value is 23.67 µm.
Conclusion: Fissures in the enamel and cement were recorded after the ultrasonic instrumentation.
