1. Reconstruction of the Long Process of the Incus by Use of Glass Ionomer Cement: Our Experience
Abstract Introduction Chronic suppurative otitis media is one of the most common causes of reversible conductive hearing loss which can lead to necrosis of the ossicles. The incus, especially its long process, is the most common ossicle affected. Objectives The present study aims to assess the use of glass ionomer cement for the reconstruction of the long

5. Ganoderma lucidum, a promising agent possessing antioxidant and anti-inflammatory effects for treating calvarial defects with graft application in rats
Abstract Purpose: Ganoderma lucidum, a kind of mushroom used for its antioxidant, anti-inflammatory, and immunomodulatory activities, was investigated in the present study for its possible healing effect on calvarial defects with bone grafts. Methods: Wistar male rats (n = 30) were divided into 3 groups: 1) the control (defect) group (n = 10), 2) defect an

6. Fibrin biopolymer as scaffold candidate to treat bone defects in rats
ABSTRACT Background: Bone tissue repair remains a challenge in tissue engineering. Currently, new materials are being applied and often integrated with live cells and biological scaffolds. The fibrin biopolymer (FBP) proposed in this study has hemostatic, sealant, adhesive, scaffolding and drug-delivery properties. The regenerative potential of an associat

9. A comparison of the sealing abilities between Biodentine and MTA as root-end filling materials and their effects on bone healing in dogs after periradicular surgery
ABSTRACT Objectives: To compare the sealing ability and biocompatibility of Biodentine with mineral trioxide aggregate (MTA) when used as root-end filling materials. Methodology: The Cell Counting Kit-8 (CCK-8) assay was used to compare the cytotoxicity of MTA and Biodentine. Twenty-one extracted teeth with a single canal were immersed in an acidic silver

10. Effect of Incudostapedial Reconstruction Using Conchal Cartilage Interposition Graft on Hearing Outcome
Abstract Introduction Chronic otitis media is a widely prevalent condition in developing countries and is a cause of correctable hearing loss. The most frequent ossicular chain defect found during surgery for chronic otitis media has been a discontinuity of the incudostapedial joint. This study observes the effect of incudostapedial reconstruction using co

11. A prospective case series on surgical treatment of circumferential and semi-circumferential defects due to peri-implantitis
Abstract Different surgical treatment strategies for peri-implantitis with the use of graft material and membranes have been suggested without any longitudinal remarkable success rate. The present preliminary study was aimed to analyze a new clinical approach based on the disinfection of the implant connection, the disinfection of the implant surface and GBR

12. Short-term use of resveratrol in alloplastic graft material applied with calvarial bone defects in rats
Abstract Purpose: The effects of resveratrol administration on calvarial bone defects with alloplastic graft material was investigated for osteoinductive reaction and bone development in rats. Methods: Healthy male rats were randomly divided into 3 groups consisting of 10 rats. Groups were as follows: control (defect) group, defect + graft group, and defec
