Paper Abstract

A comparative evaluation of the effectiveness of the Apadent Pro gel (Sangi, Japan) was performed on 15 extracted teeth in the patients aged 35 to 55 years. The teeth were divided into 5 equal groups. On the enamel of the removed permanent molars, the Apadent Pro gel was rubbed one time with an angled tip with a rubber nozzle in the first group for 10 s, in the second - 20 s, in the 3rd - 30 s, in the 4th - 50 s, in 5th - 60 s. The teeth were brushed twice a day in the morning and evening for 3 minutes. The calcium content in the surface layer of enamel was determined by the laser spectrometry (I 200 EC Applied spectra) before and after the rubbing of the Apadent Pro gel for 1, 2, 3, 6, 9, 14 days. It was found that the calcium content in the surface layer of enamel increases immediately after the rubbing of the gel in all teeth in proportion to the duration of treatment. The result remains high up to 3 days then decreases in the 1st and 2nd group and by day 14 decreases to the initial level. In the 3rd, 4th and 5th groups, the calcium content in the surface layer of enamel increases significantly, then gradually decreases. On the 14th day of observation, the caries resistance by the Ca/P coefficient is also estimated as high. According to the results of laser spectrometry, the optimal exposure time for the Apadent Pro gel on teeth is equal to 30 seconds. In the surface layer of enamel, the Ca content increases immediately after the rubbing of gel.
