Abstract

This study inspects the Oil leaching and the Degree of Conversion of Addition of Miswak (Salvadora Persica) Essential Oil to Orthodontic Adhesive. Miswak oil was prepared from the Miswak root by the green method, and was added to the Heliosit adhesive at 1%,3% and 5% respectively. The degree of conversion was measured by Fourier Transform Infrared Spectroscopy, and the amount of leached oil was estimated by Spectrophotometer. The degree of conversion data was analyzed by Friedman test where p≤0.05. The degree of conversion was not affected by the oil added to the adhesive. While the leached oil of the modified adhesive started from the first hour of curing and extended for last day of the study (one month). According to this study the addition of Salvadora Persica oil did not affect the degree of conversion of the modified adhesive. Also, the amount of oil leached from the modified adhesive began on the first day of polymerization and continued for up to one month.
