Abstract

Background: Restorative procedures present a common challenge in pediatric dentistry. This investigation aimed to assess the clinical efficacy of a recent self-adhesive bulk-fill restorative material in the restoration of occlusal and occluso-proximal lesions in primary molars.
Martials and Methods: This was randomized controlled clinical study. It involved 30 children, randomly selected and separated into two main equal groups, depending on the type of carious lesion: Group I with Class I lesions and Group II with Class II lesions. Each main group randomly separated into two equal subgroups: subgroups IA, IB and subgroups IIA, IIB. Subgroups A served as the controls and restored with Filtek™ Bulk Fill Composite. Subgroups B served as the study groups and restored with Surefil One. Restorations were assessed utilizing modified USPHS criteria, post restoration (baseline) and at follow-up periods of 3, 6, and 12 months.
Results: Intergroup comparisons of both restorative materials for Class I and Class II lesions after 12 months showed insignificant difference in marginal adaptation (p=0.329, 0.142), recurrent caries (p=1.0 each), postoperative sensitivity (p = 1.0 each), retention (p = 1.0 each) and proximal contact (p = 0.483 for Class II). Significant differences between the materials were observed for color match (p < 0.001each), anatomic form (p = 0.03 each), and surface roughness (p = 0.006, 0.01) for both Class I and Class II lesions, respectively after 12 months.
Conclusions: Conventionally bonded bulk-fill resin composite demonstrated better performance over the self-adhesive bulk-fill composite in terms of color match, surface roughness, and anatomical form.
