A prospective randomised clinical trial of one bis-GMA-based and two ormocer-based composite restorative systems in class II cavities: Three-year results

One-year clinical evaluation of direct nanofilled and indirect composite restorations in posterior teeth

“…In some clinical studies on posterior composites, rubber dam was used to isolate the teeth [21][22][23] , whereas Turkun 24) , Kohler et al 25) , and Pallesen and Qvist 26) opted for cotton rolls and saliva suction device. Raskin et al 27) , in a 10-year evaluation of posterior composites, did not observe significant differences between these two isolation methods.…”

Colour-stability and gloss-retention of silorane and dimethacrylate composites with accelerated aging

“…8 Despite the current improvements in resincomposite formulations, changes in their optical characteristics have been highlighted by clinical studies. 9 Thus, the long-term colour-stability and gloss-retention is still an area for improvement.…”

A prospective randomized clinical trial of one bis-GMA-based and two ormocer-based composite restorative systems in class II cavities: Five-year results

“…5 In short, after cavity preparation, restorative procedures were performed using rubber dam. A sectional matrix system (Palodent, USA) was used.…”

“…3,4 The 3-year results of a prospective randomized study have been published, showing no diffferences in survival and clinical behavior between ormocer-based and bis-GMA-based composites in class II cavities. 5 Since most composites presently achieve a longer lifespan, 6 it was decided to continue the observation. Therefore, the aim of the study was to evaluate the clinical performance of two ormocer-containing micro particle hybrid composite restorative systems (AD: Admira/Admira Bond, VOCO, Cuxhaven, Germany and DE: Definite/Etch & Prime 3.0, Degussa, Hanau, Germany, now out of the market) and to compare it to that of a conventional fine-particle hybrid composite restorative system (TC: Tetric-Ceram/Syntac Sprint, Ivoclar-Vivadent, Schaan, Liechtenstein, also out of the market presently).…”
