12-Months Clinical Comparison of Two Resin Composites on Diastema Closure

Objective: To evaluate the esthetic, functional and biological clinical performance of two nano-hybrid resin composite systems used for anterior diastema closure at 12-months.

Method: Twenty-three patients with anterior midline or multi-diastema problem were enrolled in this study. Nano-hybrid resin composite systems to be used on each patient were randomly selected. Thirty seven teeth of 10 patients were restored with Filtek-Z550 (3M/ESPE) in combination with Adper™ Single Bond 2 (3M/ESPE) etch&rinse adhesive; whereas 39 teeth of 13 patients were restored with Charisma-Diamond (Heraeus Kulzer) in combination with Gluma2 Bond (Heraeus Kulzer) etch&rinse adhesive by two operators. Esthetic (Surface Luster, Surface/Margin Staining, Color Match and Translucency, Esthetic Anatomical Form), Functional (Fracture of Material and Retention, Marginal Adaptation, Patient’s View) and Biological (Periodontal Response, Adjacent Mucosa, Oral&General Health) properties of the restorations were evaluated at baseline, 6- and 12-months using FDI Criteria establishing a score-range of 1-5 (1-Clinically excellent/very good, 2-Clinically good, 3-Clinically sufficient/satisfactory, 4-Clinically unsatisfactory and 5-Clinically poor) by two independent examiners. The results were evaluated using the Pearson Chi-Square (p=0.05).

Result: At 12-months, 23 patients were evaluated. Two Filtek-Z550 restorations (5.4%) and 5 Charisma-Diamond (12.8%) restorations exhibited minor surface staining (Score 2). The surface luster of 3 Charisma-Diamond restorations was scored as 2. Three Filtek-Z550 restorations (8.1%) and 1 Charisma-Diamond restoration (2.6%) were scored as 2 with minor irregularities in marginal adaptation. However, there were no significant differences between two restorative materials for surface/marginal staining, surface luster and marginal adaptation (p>0.05). All the restorations in both groups were clinically excellent (Score 1) for the rest of the esthetic, functional and biological properties assessed.

Conclusion: Both nano-hybrid resin composite systems revealed esthetically, functionally and biologically good clinical performance when used for diastema closure at 12-months.
