Electrodeposited hydroxyapatite coating on titanium after ultrashort-pulsed laser processing for a novel surface of endosseous implants.

Background: Ceramic endosseous implant coatings have gained esteem due to their favorable osteoinductive and osteoconductive properties. However, such a layer may be prone to failure under in vivo conditions, which necessitates its modification.

Objectives: The aim of the present study was to modify an electrodeposited hydroxyapatite (HA) coating on titanium (Ti) with ultrashort-pulsed lasers for the incorporation of the ceramic into the sample surface and the texturing of the metal surface.

The effectiveness of topical forms of dexamethasone in the treatment of oral lichen planus- A systematic review.

The goal of this systematic review was to assess the efficacy of dexamethasone compared to other treatments in oral lichen planus (OLP). The literature search used the following inclusion criteria: randomized controlled trials (RCT) comparing dexamethasone and other treatment strategies in patients with OLP. The outcome measures included relief of symptoms, decrement of erosive area size, and changes in quality of life.

Evaluation of the efficacy of treatment modalities in burning mouth syndrome-A systematic review.

Objectives: Burning mouth syndrome (BMS) is a medical entity characterised by a spontaneous sensation of burning, numbness or pain of the oral mucosa in the absence of clinical symptoms. The goal of this systematic review was to assess the efficacy of various current treatments for BMS.

Methods: The literature search used the following inclusion criteria: randomised controlled trials (RCTs) which compared one or more treatment strategies for patients with primary/idiopathic BMS with a placebo group describing all types of interventions.

Evaluation of human osteoblast metabolic activity in modified titanium-conditioned medium.

To evaluate human osteoblast metabolic activity cultured in medium conditioned with commercially pure titanium after surface treatments with alumina or ceramic grit-blasting followed by acid etching. Commercially available, pure Grade 4 titanium disks were used and subjected to seven different surface modifications: (1) machined (MA)-used as the control group; (2) blasted with AlO (AlO); (3) blasted with sintered ceramic (HAS); (4) blasted with non-sintered ceramics (HA); (5) blasted with AlO and etched with HCl/HSO (AlO DE); (6) blasted with sintered ceramic and etched with HCl/HSO (HAS DE), and (7) blasted with non-sintered ceramic and etched with HCl/HSO (HA DE). A samples roughness evaluation test was carried out with an interference microscope, and energy-dispersive X-ray spectroscopy was performed to evaluate the presence of aluminum, phosphorus, and calcium deposited during the titanium surface treatment along with carbon contaminants acquired by the surface during processing.

Effects of a hydroxyapatite coating on the stability of endosseous implants in rabbit tibiae.

Background: A dental implant surface which would promote rapid and strong osseointegration is a key factor of success in modern implantology. To achieve this goal, different implant surface modifications are developed. A hydroxyapatite (HA) coating changing a bioinert titanium surface into bioactive is one of them.

Hydroxyapatite coating on titanium endosseous implants for improved osseointegration: Physical and chemical considerations.

Background: For many years, hydroxyapatite (HA) has been used as a bioactive endosseous dental implant coating to improve osseointegration. As such, the coating needs to be of high purity, adequate thickness, crystalline, and of a certain roughness in order to stimulate rapid fixation and form a strong bond between the host bone and the implant. There are a number of ways of preparing the HA coating, resulting in various coating properties.

Osteoblastic cell behaviour on modified titanium surfaces.

Introduction: The surfaces of endoosseous dental implants have been subjected to numerous modifications in order to create a surface which can provide rapid bone healing and fast implant loading. Each modification has involved changes to the chemical composition and topography of the surfaces which have resulted in various biological reactions to the implanted material.

Aim: The aim of this study was to evaluate the surface topography and chemistry of various modified titanium surfaces: (1) machined surface (MA), (2) alumina-blasted (Al2O3), (3) alumina-blasted and acid-etched (Al2O3 DE), (4) hydroxyapatite/tricalcium phosphate grit-blasted (HA/TCP) and (5) hydroxyapatite/tricalcium phosphate grit-blasted and acid-etched (HA/TCP DE) and to analyse the effects of surface roughness, and chemical composition on human osteoblast vitality, differentiation, morphology and orientation.
