Clinical Trial Summary
Thus, the present study aimed to evaluate the longevity of direct composite compared to
indirect ceramic laminate veneers in multiple diastema closure cases using USPHS criteria.
The formulated null hypothesis was that there is no significant difference in the clinical
performance of direct composite and indirect ceramic laminate veneers in multiple diastema
closure cases over two years.
Description:
Restorative materials and curing device In the current study, the manufacturer's instructions
were followed for the use of the nanofilled composite resin (Estelite Asteria, Tokuyama
Dental, Japan) for direct laminate veneers and IPS e.max Press (Ivoclar Vivadent, Amherst,
NY, USA) for indirect laminate ceramic veneers. A light curing device with an output density
of 655 mW/cm2 (LED Bluephase C5, Ivoclar, Vivadent, Amherst, NY, USA) was used. Demetron LED
light meters were used to measure the light curing unit's intensity regularly (Demetron
Research Corp., Danbury, CT, USA). Brand name, description, chemical composition, and
manufacturers of the materials are presented in Table 1.
Study design, blinding & randomization The Consolidated Standards of Reporting Trials
statement was adhered to in the description of the experimental design. This study was a
randomized controlled clinical trial that was double-blinded for both trial participants and
outcome assessors. Randomization was performed using the flip of a coin for the choice of
material. Using computerized sequence generating (www. randomizer.org), participants were
divided into two groups with a 1:1 allocation ratio.
