Abstract:
ABSTRACT :Restorative treatment is very challenging for non-carious cervical lesions (NCCLs) due to functional
and structural complexities. The purpose of this randomised controlled trial (RCT) was to evaluate
the clinical performance of nanocomposite restorations bonded using universal adhesive in self-etch
mode with and without air abrasive surface treatment for NCCLs. A total of 70 NCCLs, from a group
of consenting patients who fulfilled the inclusion criteria, were recruited for the study. The study was
carried out following CONSORT guidelines. Block randomisation was done for equal allocation
of lesions into; Group 1 (surface treatment with alumina air abrasion) and Group 2 (control group
without mechanical surface treatment). The lesions were restored with nanocomposite using a universal
bonding agent in self-etch mode. The clinical performance of the restorations was evaluated by two
examiners using modified United States Public Health Service (USPHS) criteria at baseline, 3 months,
6 months and 12 months. A Chi-square test was performed for inter-group comparison. Cochran’s Q
test and Dunn’s post hoc analysis were used for intra-group comparison. The inter-group comparison
revealed no statistically significant difference between the experimental and control group for all the
parameters assessed. With the intra-group analysis, it was found that there was a significant decrease
in the performance of the restorations concerning marginal staining, marginal adaptation and surface
texture during the evaluation period (p < 0.05). However, all of them demonstrated clinically acceptable
performance. According to the results of this RCT, it was concluded that airborne particle abrasion
of NCCLs did not improve the clinical performance of nanocomposite resin bonded using universal
adhesive.
