Microleakage of temporary filling materials

Cavit and Systemp.inlay are frequently used temporary filling materials among the various materials available on the market. Although both materials are clinically acceptable in the everyday work, the objective of this study was to examine the marginal leakage degrees of Cavit G and Systemp.inlay. The study was made on 60 mandibular and maxillary molars, extracted for periodontal reasons. The samples were randomly divided into two groups of 30 teeth each. The preparation of the Class I cavity was made on each tooth. The cavities were then filled with temporary materials following the manufacturers instructions. After that, the surface of each tooth was coated with two layers of a nail polish and the teeth were immersed in a contrast solution for ten days. The teeth were then rinsed with water and cut down with a diamond disk in the buccal-lingual direction. The depth of ink penetration was measured by a stereomicroscope. The average value of the ink leakage degree was calculated for each material and Wilcoxon Rank Sum Test was used to prove the existence of a statistically significant difference. Cavit demonstrated better marginal sealing properties than Systemp.inlay, in whose case the marginal leakage was considerably greater.
