PENGARUH VARIASI PH SALIVA TERHADAP KEKUATAN TARIK DIAMETRAL RESIN KOMPOSIT NANOHYBRID

Introduction : Nanohybrid composite resin is a restorative material that often used because of its aesthetics and adequate mechanical properties. One the properties nanohybrid resins diametral tensile strength, which affects strength when receiving chewing loads in oral cavity. The value can be influenced by several factors, namely food, drink, saliva. Human saliva has different pH levels always interacts with materials Objective To determine effect salivary variations on resin. Methods: study were (Filtek Z250 XT, 3MESPE, USA), artificial 4, 7, 10. type research was true experimental laboratory posttest-only control group design, measured had been immersed three treatment groups, 10, total 27 samples using Universal Testing Machine (JTM, Taiwan). results obtained analyzed for one- way post-hoc LSD variance. Results Samples at acidic lowest average (39.09 MPa) compared to neutral (57.54 alkaline (49.13 MPa). Statistical analysis showed significant differences between groups (p<0.05). Conclusion: greater than or basic
