Summary

The aim of this study was to evaluate the clinical performances of nano-hybrid resin composite systems used for anterior diastema closure and tooth reshaping at 4 years in service using FDI Criteria.

Twenty-three patients with diastema problem were enrolled. Nano-hybrid resin composites to be used on each patient were randomly selected. Thirty-seven teeth (10 patients) were restored with Filtek-Z550 (3M/ESPE) in combination with Adper™ Single Bond 2 (3M/ESPE) in Group 1; whereas 39 teeth (13 patients) were restored with Charisma-Diamond (Heraeus Kulzer) in combination with Gluma2 Bond (Heraeus Kulzer) in Group 2, by two operators. Esthetic, functional and biological properties of the restorations were evaluated at baseline, 1-4 years using FDI Criteria establishing a score-range of 1-5. The data were evaluated using the Fisher's Chi-Square (p=0.05).

Conditions

  • Diastema

Interventions

OTHER

Charisma-Diamond

The surfaces were etched using 35% phosphoric acid for 30 s. The etched surfaces were rinsed and dried. Nano-hybrid resin composite system was used Charisma-Diamond in combination Gluma2 Bond etch\&rinse adhesive. The composite increments were carefully placed between the matrix strip and tooth by using a hand instrument. The composite resin restorations were light-cured (600 mW/cm²). Occlusion was checked with thin articulating papers. Restoration surfaces were finished and polished with fine finishing diamond burs, stones and rubber cups whereas; proximal and labial surfaces were contoured and polished with finishing strips. The treatments were completed by instructing the patients about the oral hygiene measures for cleaning their restorations with toothbrush and dental floss.
