“…In a previous study, extracted molars were subjected to root canal formation, filling, and then coronal restoration was performed with different restorative materials. In break strength testing, the fracture strength was clearly lower in the molar repaired with IPS Empress CAD than that repaired with Celtra DUO, showing that material properties vary greatly even among ceramics (13). …”

BackgroundThis study aimed to evaluate the effect of dental prophylaxis on the surface gloss and roughness of different indirect restorative materials for computer-aided design/computer-aided manufacturing (CAD/CAM): two types of CAD/CAM composite resin blocks (Shofu Block HC and Estelite Block) and two types of CAD/CAM ceramic blocks (IPS Empress CAD and Celtra DUO).Material and MethodsAfter polishing the CAD/CAM blocks and applying prophylaxis pastes, professional dental prophylaxis was performed using four different experimental protocols (n = 5 each): mechanical cleaning with Merssage Regular for 10 s four times (Group 1); four cycles of mechanical cleaning with Merssage Regular for 10 s and Merssage Fine for 10 s (Group 2); four cycles of mechanical cleaning with Merssage Regular for 10 s and Merssage Fine for 30 s (Group 3); and mechanical cleaning with Merssage Fine for 10 s four times (Group 4). A glossmeter was used to measure surface gloss before and after mechanical cleaning, and a contact stylus profilometer was used to measure surface roughness (Ra).ResultsPolishing with prophylactic paste led to a significant reduction in surface gloss and increase in surface roughness among resin composite blocks, whereas the polishing-related change in surface gloss or roughness was smaller in Celtra DUO, a zirconia-reinforced lithium silicate block.ConclusionsChanges in surface gloss and roughness due to polishing with a prophylactic paste containing large particles were not improved by subsequent polishing with a prophylactic paste containing fine particles. Key words:CAD/CAM, professional dental prophylaxis, prophylactic paste, surface gloss, surface roughness.

“…Cuspal coverage is generally desirable for the restoration of endodontically treated teeth, [25] since the preparation of an access cavity, canal enlargement during endodontic procedures, and use of specific chemicals during endodontic treatment would have significantly reduced the tooth strength. [26,27] It is well known that tissue conservation is the most critical issue when dealing with a non-vital tooth.…”

“…Somewhat similar to this study, Sorrentino’s study exhibited samples restored with posts, which showed mainly repairable fracture, while teeth restored without posts showed mostly irreparable failure (25). Overall, it seems that loss of hard tissue due to root canal treatment have to be considered responsible for the increased fracture risk of ETT especially unfavorable fracture (26,27). The authors recommend further laboratory studies examining bond strength and leakage using other materials.…”

BackgroundEndodontically treated teeth are widely considered to be more susceptible to fracture than vital teeth. Obturation procedures and post placement have been a main cause of vertical root fracture.Material and MethodsForty-eight human premolars with standardized weakened roots were endodontically treated and allocated to four experimental groups (n=12). After root canal treatment, in group 1, fiber posts #1 were cemented in root canals using Estelite Core Quick, and the crowns were restored with resin composite. For group 2 and 3, the roots and crowns were restored using a light-cured and self-cured adhesive and resin composites respectively. In group 4, it was used the Panavia F 2.0 resin cement and resin composite for corono-radicular reconstruction. In group 5, the teeth remained untouched. After 24 hours storage and 1000 thermocycles, samples were loaded at a cross head speed of 1 mm per minute.ResultsA significant difference was observed in fracture resistance among groups 4 and 5 compared to other groups.ConclusionsRoot reconstruction with fiber post and Panavia resin cement, and crown building using light-cured resin composite resulted in increased fracture resistance equal to that of intact teeth. Key words:Fracture resistance, fiber post, resin cement, resin composite.
