COMPARATIVE EVALUATION OF VARIOUS TECHNIQUES OF IMPROVING RETENTION OF CENTION N IN CERVICAL LESIONSAN IN VITRO STUDY

Abstract

AIM:
To evaluate and compare various techniques of application of Cention-N in class V cavity
and check its flexural strength and fracture resistance.
METHODOLOGY:
30 intact permanent teeth will be selected and ideal class V cavity was prepared. The teeth
were divided into 3 groups of 10 each and restored with Cention N- Group A- with
conditioning, Group B- after etching and bonding, Group C- without conditioning.
Further, teeth were subjected to occlusal load, increasing from increasing load of 50 to 100
Mpa and detachment of restoration was observed. The flexural strengths of the samples were
determined.
STATISTICAL ANALYSIS: One way Anova and Post Hoc Tukey HSD (beta) has been
used for compare and evaluate three different techniques of application of Cention N.
RESULTS: The application of dentin conditioning agent prior to placement of Cention-N in
cervical lesion provides a far better chance of retention than the use of etchant and bonding
agent or without using any conditioner. However the difference between the groups was
statistically insignificant.
