The adhesive systems were represented by Opal Bond MV Composite and Opal Seal (Ultradent), respectively the fluoride releasing Transbond light cure adhesive paste and Transbond XT (3M). The utilised brackets were Avex metal bracket system (Ultradent), respectively Unitekô Miniature Twin Metal Brackets (3M). The study was realized on 4 groups of extracted teeth: the first and second groups by using the products of the manufacturer Ultradent, respectively 3M, and the third and fourth groups by using the adhesive system of one manufacturer and the brackets of the other manufacturer. The study revealed that the use of adhesive system and brackets of the same manufacturer may increase the shear bond strength and decrease the adhesive remnant index.
