This study was conducted to evaluate the effect of two types of cola drinks (Regular and Diet) on the surface microhardness and surface roughness of three types of composite resins; Filtek P60 (Packable composite), Tetric-N-Ceram (Nanohybrid composite) and Swisstec (Conventional composite) in which composite samples were alternately immersed manually, 5 seconds each, in cola drink and artificial saliva for 10 cycles at room temperature which repeated three times a day (8am,4pm,12am) at 8hours intervals for one week. Total numbers of (180) samples were prepared, (60) samples for each type of composite, were divided into two main groups (30) subjected for microhardness test (by Vickers hardness tester) and (30) subjected to surface roughness test (by profilometer). For each type of composite resin group, the (30) samples were subdivided as follows: - Group (1): Ten samples were immersed in regular Pepsi cola. Group (2): Ten samples were immersed in diet Pepsi cola drink. Group (3): Ten samples were immersed in artificial saliva. The results revealed that cola drinks showed reduction in means VHN (Vickers hardness number) values and increasing in means Ra (Roughness average) values for all types of composites for all groups. Filtek P60 (packable) composite resin had the highest VHN values followed by Tetric-n-Ceram (nanohybrid) composite and Swisstec (conventional) composite respectively. Surface microhardness results showed that cola drinks affect the Filtek P60 (packable) composite resin significantly while their effect was with high significant difference for Swisstec (conventional) composite and Tetric-n-Ceram (nanohybrid) composite resin, so the influence of cola drinks was material dependent. Diet Pepsi cola showed reduction in means VHN values and increasing in means of Ra values for all types of composites for all groups more than regular Pepsi cola. The neutralizable acidity results revealed that regular Pepsi need lesser amount of NaOH to reach the neutrality than diet Pepsi in spite of the acidity of regular Pepsi is more than diet Pepsi. Tetric-n-Ceram (nanohybrid) composite had the lowest (Ra) values (lowest roughness) followed by Filtek P60 (packable) composite and Swisstec (conventional) composite respectively. Surface roughness results showed that Filtek P60 (packable) composite resin affected non significantly in regular Pepsi and significantly in diet Pepsi, while Tetric-n-Ceram (nanohybrid) composite and Swisstec (conventional) composite showed a high significant difference in both cola drinks, so the influence of cola drinks were material dependent. All types of composites tested in this study showed reduction in VHN values and increasing in means of Ra values after 7 days of immersion in artificial saliva, but the effect was a non-significant.

To determine the amount of apically extruded debris during root canal preparation with of DentsplyProTaper Universal (PTU), ProTaper Gold (PTG), and ProTaper Next (PTN) nickel titanium (NiTi) rotary files was evaluated in comparision with simulated files with same design and our study design. Methods: For PTU and PTG study design modification is to leave the apical 8 mm of S1 and the apical 3 mm of S2 as un-milled, F1 only the apical 5 mm would have cutting blades. For PTN is to leave the apical 8 mm of X1and, while for X2 is to leave the coronal 8 mm as un-milled. Ninety human mandibular second premolar teeth were decoronated to a 15mm length, an apparatus with minor modifications of the Myers and Montgomery experimental model was used, after canal preparation was stored in an incubator in order for water evaporation leaving only the extruded debris, then the vials were transmitted to the electrical balance for re-weighing. Conclusions: Leaving the portion of the file which supposes not to make canal preparation blank (without flutes) decreases the amount of debris extrusion in all protaper systems.

Background: CF (Cyclic Fatigue) resistance of Dentsply Pro Taper Universal (PTU), Pro Taper Gold (PTG), and Pro Taper Next (PTN) nickel titanium (NiTi) rotary ϔles was evaluated in comparision with simulated ϔles with same design and our study design. Methods: For PTU and PTG study design modϔcton is to leave the apical 8 mm of S1 and the apical 3 mm of S2 as unmilled, F1 only the apical 5 mm would have cutting blades. For PTN is to leave the apical 8 mm of X1 and, while for X2 is to leave the coronal 8 mm as un-milled. Ten instruments for each ϔle (S1, S2, F1, X1 and X2); total 240 ϔles (80 pieces for Dentsply, 80 pcs for simulated and 80 pieces for study design), ϔles rotated in simulated canal until fracture. Conclusion: PTG instruments were most resistant to CF, followed by PTN and PTU. S1 and S2 ϔles making the non-active part plane will increase CF resistance while for F1 ϔles will decrease CF resistance. For PTN ϔles groups, for X1 ϔles making the non-active part plane will increase CF resistance while for X2 ϔles will decrease CF resistance.
