ABSTRACT
This investigation evaluated the effect of laser etching and acid etching techniques on the marginal leakage beneath Vitadur N porcelain laminate veneers bonded either entirely on enamel, or with cervical margin located on root dentine of prepared extracted maxillary central incisors. Two different composite resin luting systems [light cured, or light and chemical cured] were used and compared. The bonded specimens were thermocycled and by employing the Standard dye penetration technique the leakage was scored from cervical and incisal margins. The least marginal leakage was observed beneath laminate veneers bonded entirely on enamel. Laser etching improved the scaling qualities of veneers with cervical margins on root dentine below the CEJ. Statistically insignificant differences were observed with the use of the two different composite resin luting systems
