MICROLEAKAGE IN DENTISTRY AND MICROLEAKAGE EVALUATION TECHNIQUES

Mikroleakage is a multifactorial biological phenomenon in dentistry. There are many studies, test methods, usefulness and reliability data in the literature to prevent microleakage which affects the durability of the restoration badly or which causes discoloration, post operative sensitivity and seconder caries. The investigations are being done to provide better compliance with the tooth structure by the improvement of the structure qualities of dental materials and the application techniques to prevent microleakage. Several test methods have been introduced and tested for the evaluation of microleakage. These test methods are include; dye penetration, radioisotopes, chemical agents, bacterial test methods, air pressure, neutron activation analysis, electrochemistry and microscopic analysis techniques. In this article these test methods used for the evaluation of microleakage and interpretations on their advantages and disadvantages have been presented.
