Background and Aim: Marginal adaptation has a significant role in the success and longevity of indirect restorations. This experimental study compared the effect of intraoral and extraoral scanning on the marginal adaptation of the crowns which was made using the CEREC AC system. Materials and Methods: A Typodont maxillary first molar was prepared and served as the master die for an all-cera...

Twenty-six patients, 5-13 years of age, demonstrated 67 pairs of contralateral occlusal fissure and buccal, or lingual pit carious lesions which were restored with a spherical high-copper amalgam. One restoration of each pah" was allowed to remain as carved, while the other was finished and polished 24 hours after insertion. Each restoration was evaluated clinically by three independent examine...

objectives: this study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. materials and methods: class v cavities (4x2x2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. in the control group, single bond (sb) adhesive was applied after etching. in bb+sb...

Introduction: The giomers are a family of dental materials that allow faster effect and better functional, esthetic mechanical properties. Objective: To analyze the restorative ability between giomer type II glass ionomer in class I cavities. Methodology: A mouth split design was carried out which 27 permanent molars ICDAS 4, 5 or 6 were filled with (14) (13), respectively, patients high medium...
