On the base of those studies the cohesion of the junction and the type of adhesion of the both structures were noted. Etching of the enamel in all study groups appeared to be advantageous and resulted in improved tightness and cohesion of the fillings. The most favourable results were observed in the groups prepared with a laser and Carisolv gel, slightly worse results were obtained in the groups prepared with the use of a drill and sand\- blasting machine. The analysis of the junction with the dentine showed that the lack of etching of the dentine seemed to have an advantageous effect in all study groups."]
