Methods
Throughout the Nov-07/Jan-08 time period, 60 class-V restorations have been performed.
In order to be part of the study, every patient was to need at least 2 restorations on vital teeth, which had to be located on opposite quadrants of the oral cavity. All the restorations were made with micro-layering technique using Swiss Master Light (EMS) curing light (800 mW/cm2 for 20s). The test groups were randomly assigned to the class V cavities using composite and adhesive materials as follows:
A) testing material - Venus-Diamond and GlumaComfortBond (Heraeus)
B) competitor - CeramX-Duo and Prime&Bond-NT (Dentsply)
A quadrant-based randomization was used to assign to every restoration its filling material and adhesive system: restorations have been performed according to the adhesive dentistry techniques by one expert clinician (>10 years of clinical experience). Each restoration was polished with the 2-step polishing system provided by Heraeus Kulzer (pre-polisher and high-gloss finisher). The polishing time used has been 20s with the pre-polisher and 40s with finisher.
Results
Clinical evaluations were made by 2 independent clinicians with more than 80% of agreement using a visual loop (4.5x). Four year controls have been executed with USPHS evaluating system. None of the restorations received a Charlie rating. The restorations received 65% (Venus-Diamond) and 57% (CeramX-Duo) Alpha ratings for surface texture.
The defects/gaps in marginal adaptation score was recorded as increased. Some restoration was lost: in testing material 23% and in competitor-group 30%. We noticed a 35% in (A) and a 38% in (B) rated Bravo for color matching ability. No restorations showed post-operative sensitivity or endodontic treatment needed and no adverse events were reported.
Conclusions
In this clinical trial testing material behave with some slight advantages compared to the competitor.
