Shear Bond Strengths of Composite Resin Used to Repair Lithium Disilicate and Feldspathic CAD/CAM Ceramics Treated by Different Lasers (A Comparative in vitro Study)
Author(s): Ola Mohammed Abdul Kadhim* and Mohammed Rashid Aljuboury
Aim: This study aimed to evaluate and compare the effect of surface treatments with HF acid, Nd:YAG and Er,Cr:YSGG lasers radiation on Shear Bond Strength (SBS) of nano-hybrid composite resin bonded to two different ceramic materials. Materials and methods: Sixty specimens of (14*12*3 mm) were prepared from ceramic blocks and divided into two groups (n=30) depending on the type of ceramic materials: Group A: Feldspathic ceramic (cerec block CPC 14/A2C; Sirona dental, Germany) and group B: Lithium disilicate (IPS e.max CAD HT/A2; Ivoclar Vivadent, Shann, Liechtenstein). The obtained specimens were further allocated into six subgroups (n=10) according to the surface treatment methods; A1 and B1: 4.5% HF etching, A2 and B2: 3W Nd:YAG laser, A3 and B3: 3W Er,Cr:YSGG laser. Three additional specimens for each group were prepared for SEM analysis... Read More»
