The cytotoxicity of nine soft and hard lining materials (Mollosil Plus, Ufi Gel SC, Visco-gel, Molloplast-B, GC Tissue Conditioner, Vertex Rapid Simplified, GC Reline Hard, Vertex Self-Curing, Ufi Gel hard C) was evaluated using human gingival fibroblasts (HGFs). Twelve disk samples per lining material were prepared and incubated for 24, 48, 72, and 96 h. Cytotoxicity of each lining material's ...

The use of immediate implant placement and immediate provisionalization techniques are paramount to the maintenance for aesthetic hard and soft tissue structures. This is particularly important when implant-supported restorations are utilized in the aesthetic zone. A purpose of the custom-fabricated provisional abutment and restoration is to guide the hard and soft tissue response during healin...

Introduction: Sarcomas are rare malignancies with aggressive biological behavior. They are categorized into soft and hard tissue types. The main objective of this study was to analyze the prevalence of head and neck sarcomas (HNS) among the Iranian population. Materials and Methods: The pathology files derived from Iran National Tumor Bank of Cancer Institute in Imam Khomeini Hospital, affiliat...

For many years, glass-polyalkenoate cements have been described as possessing the unique properties of self-adherence to human hard tissues, such as bones or teeth. However, direct experimental evidence to prove the existence of chemical bonding has not been advanced. X-ray Photoelectron Spectroscopy (XPS) was used to analyze the chemical interaction of a synthesized polyalkenoic acid with enam...

This article will describe how a hard tissue laser is used in various restorative procedures. The erbium family of lasers (Er,Cr:YSGG and Er:YAG) are highly absorbed in water and, to a lesser extent, in tooth mineral. Because a carious lesion contains significantly more water than healthy enamel or dentin, the laser can offer some selectivity in removing the diseased material. Furthermore, thes...

Objective: The purpose of this review was to examine how tissue architecture, surgical procedures, implant components and prosthetic factors contribute collectively toesthetic success in the maxillary anterior and premolar region (esthetic zone).Materials and methods: Pubmed, Embase and the Cochrane electronic databases weresearched for prospective human studies that investigate sin...

Continuously increasing life expectancy results in a rising number of bone diseases and fractures. Replacements from natural sources are not only limited in their availability, they also have some serious disadvantages such as possible immunological reactions or transmission of diseases. New synthetic biodegradable materials based on photopolymers could be an alternative solution. In these inve...

Interface tissue engineering (ITE) is a rapidly developing field that aims to fabricate biological tissue alternates with the goal of repairing or regenerating the functions of diseased or damaged zones at the interface of different tissue types (also called "interface tissues"). Notable examples of the interface tissues in the human body include ligament-to-bone, tendon-to-bone and cartilage-t...

Scaffolds have been utilized in tissue regeneration to facilitate the formation and maturation of new tissues or organs where a balance between temporary mechanical support and mass transport (degradation and cell growth) is ideally achieved. Polymers have been widely chosen as tissue scaffolding material having a good combination of biodegradability, biocompatibility, and porous structure. Met...

Background and Aim: Diode laser is a great choice for soft tissue surgery. The diode laser is partially absorbed by hard dental tissues, making it safe for soft tissue surgery. This study aimed to compare the tissue thermal changes induced by three types of diode lasers at 810, 940, and 980nm wavelengths. Materials and Methods: In this in-vitro experimental study, using a diode laser device (c...
