Background: Surface chemistry of dental implant plays an important role in osseointegration. Heat treatment might alter surface chemistry and result in different biological response. The aim of this study was to investigate the roles of heat treatment of H2O2/HCl-treated Ti implants in cell attachment, proliferation and osteoblastic differentiation. Material/Methods: Sandblasted, dual acid-etched and H2O2/HCl heat-treated discs were set as the control group and sandblasted, dual acid-etched H2O2/HCl-treated discs were the test group. Both groups' discs were sent for surface characterization. MC3T3-E1 cells were seeded on these 2 groups' discs for 3 hours to 14 days, and then cell attachment, cell proliferation and cell differentiation were evaluated. Results: Scanning electron microscope analysis revealed that the titanium discs in the 2 groups shared the same surface topography, while x-ray diffraction examination showed an anatase layer in the control group and titanium hydride diffractions in the test group. The cell attachment of the test group was equivalent to that of the control group. Cell proliferation was slightly stimulated at all time points in the control group, but the alkaline phosphatase (ALP) activity and osteocalcin (OC) production increased signiﬁcantly in the test group compared with those in the control group at every time point investigated (p<0.05 or p<0.01). Moreover, the osteoblastic differentiation-related genes AKP-2, osteopontin (OPN) and OC were greatly up-regulated in the test group (p<0.05 or p<0.01). Conclusions: The results implied that surface chemistry played an important role in cell response, and H2O2/HCl etched titanium surface without subsequent heat treatment might improve osseointegration response.

This study was aimed to assess the effect of anodized and alkali-heat surface treatment on the bioactivity of titanium alloy (Ti-6Al-4V) after immersion in Hank's solution for 7 days.
The physical and chemical characteristics of the titanium implant surface have been shown to influence dental implant fixation. However, the underlying mechanism by which sandblasted, large-grit, acid...
The esthetic challenges of using all-titanium alloy abutments have led to the increasing use of prefabricated titanium inserts bonded to tooth-colored abutments and fixed dental prostheses. Optimal bo...
The effect of nonthermal plasma on the surface characteristics of commercially pure titanium (cp-Ti), and on the shear bond strength between an autopolymerizing acrylic resin and cp-Ti was investigate...
This study explores the effect of laboratory and industrial steaming on mussels with toxin concentrations above and below the legal limit. We used mild conditions for steaming, 100 °C for 5 min in in...
A Randomized controlled Clinical trial including 96 patients in which aim is to investigate the clinical outcome of dental implants in titanium-zirconium alloy compared to traditional tita...
This is a single center study for adult females or males ages 25 to 75 years who are seeking treatment for etched-in fine lines of the cutaneous lip, and/or radial cheek area, and/or nasol...
In Quebec, thousands of workers are concomitantly exposed to heat and chemical compounds. Exposure to heat induces physiological responses that help maintaining a stable body temperature. ...
The main goal of this study is to look at the way gums heal around dental implants placed in healthy patients compared to patients with type 2 diabetes. This study is designed to answer th...
The purpose of this study is to assess the change of crestal bone level at the Titanium Zirconium (TiZr) compared to Titanium (grade IV) implant between surgery and 6, 12, 24, and 36 month...
Treatment modality for DENTAL CARIES that uses manual excavation method and GLASS IONOMER CEMENTS. Because of its noninvasiveness and no need for expensive equipment and anesthesia it is promoted as an approach in places where dental care is not readily available.
The application of heat to raise the temperature of the environment, ambient or local, or the systems for accomplishing this effect. It is distinguished from HEAT, the physical property and principle of physics.
Treatment for the prevention of periodontal diseases or other dental diseases by the cleaning of the teeth in the dental office using the procedures of DENTAL SCALING and DENTAL POLISHING. The treatment may include plaque detection, removal of supra- and subgingival plaque and calculus, application of caries-preventing agents, checking of restorations and prostheses and correcting overhanging margins and proximal contours of restorations, and checking for signs of food impaction.
A commonly used prosthesis that results in a strong, permanent restoration. It consists of an electrolytically etched cast-metal retainer that is cemented (bonded), using resins, to adjacent teeth whose enamel was previously acid-treated (acid-etched). This type of bridgework is sometimes referred to as a Maryland bridge.
The property of dental enamel to permit passage of light, heat, gases, liquids, metabolites, mineral ions and other substances. It does not include the penetration of the dental enamel by microorganisms.
Dentistry is the study, management and treatment of diseases and conditions affecting the mouth, jaw, teeth and their supporting tissues (Oxford Medical Dictionary) The work of a dentist ranges from regular patient check-up to orthodontics and surgery....
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
