Abstract :
Background and Objectives: The foremost goal of any
clinician is providing the patient with a restoration
which preserves the longevity of fixed partial dentures
and regaining the lost function. In the oral environment,
dental luting agents must withstand masticatory and
parafunctional stresses. They should maintain their
integrity while transferring stresses from crowns or fixed
partial dentures to tooth structure. The purpose of this
in vitro study was to compare and evaluate the diametral
tensile strength of four commercially available luting
cements.
Method: A total of 120 samples were prepared of which
30 samples were prepared for Group A (GC gold label 1
luting and lining cement), 30 samples for Group B
(Ivoclar Vivaglass cem), 30 specimens for Group C (3M
ESPE Rely X Luting cement) and 30 specimens for
Group D (Kerr Nexus RMGI). Pre formed polyethylene
molds measuring 6.0±0.1 mm in diameter and
3.0±1. 0mm in thickness (ISO Standard 9917) are
machined to prepare standardized cylindrical cement
blocks. In these groups, based on duration of immersion
in artificial saliva each group will be subdivided into
three subgroups of 10 samples each.
