Fiber Post Removal: Comparative Study Using a New Post Concept
2009
Objectives: To evaluate the time required to remove endodontic posts made of quartz and glass fibers, and compare them to a new glass fiber post designed for easy removal on the basis of efficiency and tooth damages. Methods: 40 human single-rooted teeth were treated endodontically and randomly assigned to four fiber posts groups: 1) was restored with Premier#90 (Innotech); 2) with DT#2 Lightpost (Dentsply); 3) with Unicore#3 (Ultradent); 4) with a special, soft-cored “S” glass fiber post ER-Prosthetic#3 (Overfibers). An impression of the canal was taken prior post cementation. The posts were luted with Panavia F and adhesive (Kuraray). All the specimens were mounted in a dental simulation …
Infiltrazione marginale di tre sistemi di cementazione per inlay in composito: comparazione in vitro
2007
Lo scopo del presente studio è quello di valutare in vitro l'infiltrazione marginale di inlays in composito cementati con tre differenti materiali. Su 36 molari e premolari estratti per motivi ortodontici o parodontali, sono state eseguite preparazioni MOD con margine cervicale sullo smalto. Dopo aver rilevato le impronta in polietere, sono stati realizzati gli inlays in resina composita. I campioni sono stati divisi casualmente in 3 gruppi: Gruppo1 cemento composito microibrido duale (Calibra, Dentsply, York, USA); Gruppo2 composito Flow (Charisma® flow, Heraeus Kulzer, Hanau, Germany); Gruppo3 cemento composito autoadesivo universale ( Relyx Unicum, 3M Espe). I campioni di ogni gruppo son…
