Aortic stenosis (AS) often requires surgical aortic valve replacement (SAVR). Patient-prosthesis mismatch (PPM) can lead to suboptimal outcomes. Von Willebrand factor (VWF), crucial for hemostasis, is altered in AS patients. As part of an ongoing study, this research focuses on the impact PPM immediate postprocedural VWF levels SAVR patients, building upon our previous publication short-term dynamics and TAVR. This prospective study included 31 consecutive patients with severe undergoing...

Forty-eight plates sectioned rectangular slices. immersed distilled at 37 °C for period 28 days, then subjected aging by thermal cycling (10,000 cycles). Surface...

Oral health-related behaviors and living conditions play an important role in general oral health. This study aimed to evaluate caries prevalence severity schoolchildren residing rural urban areas of Romania, correlate these with behaviors. An estimation the required sample size was conducted (sampling error ±3% at a 95% confidence level), followed by stratification administrative units then selection 49 schools. The Hurdle approach used analyze dataset, requiring two sets analyses for each...

The aim of the present study was to formulate new variants synthetic and animal-source bone materials coated with different biopolymers, containing antibiotics (ampicillin oxacillin) alendronate drugs. Validation consists in establishing mixtures that do not interactions between components. These should act as a drug delivery system alongside base. Natural polymers such chitosan, alginate, kappa-carrageenan have been shown be optimal for due their intrinsic biocompatibility. Binary, ternary,...

(1) Background: PETG (polyethylene terephthalate glycol) is a transparent, inexpensive, and versatile thermoplastic biomaterial, it increasingly being used for variety of medical applications in dentistry, orthopedics, tissue engineering, surgery. It known to have remarkable properties such as tensile strength, high ductility, resistance chemical insults heat, but can be affected by various environmental conditions. The aim the present study was evaluate topographical characteristics four...

The aim of this study was to evaluate the accuracy two intraoral scanners used in dental office. A molar fixed a typodont prepared for ceramic onlay. preparation scanned using high-resolution scanner (reference scanner) and saved as stereolithography (STL) format. resin again scanners, all scans were well STL All files compared metrology software (Geomagic Control X). Overlapping meshes allowed assessment terms trueness precision. Based on results study, differences precision between minimal.

Background and aims. The development of dental implantology is based on a thorough examination the interaction implants with surrounding tissues, as well methods stimulating osteogenesis around implants. Consequently, most common approach to restore lost function in terms aesthetics now treating partially edentulous individuals study's objective was assess how effectively implant prosthetic treatments performed only reconstruction conjunction abutment teeth. Methods. A total seven years...

Clear thermoplastic materials have increased in popularity the dental field due to their various applications, combination of excellent aesthetics, and good biomechanical behavior, but they may be influenced by different environmental conditions. The purpose present study was assess topographical optical characteristics appliances relative water sorption. PET-G polyester were evaluated this study. Related uptake desiccation stages, surface roughness analyzed, three-dimensional AFM profiles...

The removal of etiological factor such as plaque and tartar is great importance in order to obtain smooth tooth surfaces free pathogenic microflora consisting the all roughness on surface, especially cement, which would favour deposits bacterial main aetiological periodontal disease. This paper aims highlight scaling proper oral dental hygiene for health. Most patients subject treatments require more frequent prophylactic treatments, every three months, instead usual six because their...

The process of re-demineralisation is governed by the degree mineral saturation oral fluids. Due to positive changes in conditions, remineralisation can become predominant leading healing injuries. To improve remineralisation, it necessary increase concentration calcium and fluoride For this purpose, fluorides have traditionally been used varied forms concurrently, cariostatic mechanism be explained increasing force fluorapatites. aim paper was demonstrate importance using toothpastes...

Purpose of the articleto carry out an epidemiological study on use sealing as a method preventing dental caries and to assess tightness integrity over time composite resins used seal pits fissures using VistaCam iX intraoral fluorescence camera. Based premise that dentists do not have enough confidence in caries, we assessed if is current practice prevention metod tooth decay, measured, with high performance camera such device, resin seals.

The main factor in maintaining oral hygiene is first and foremost the correct dental brushing use of proper sanitizing means: toothbrush, toothpaste, floss, mouthwash. Toothpastes containing hydroxyapatite have an increased efficiency due to ability re-mineralize enamel. In view appearance secondary reaction products, most acceptable variant for HA production between calcium hydroxide phosphoric acid, because it does not result any undesirable side products at a pH ] 9 units. purpose this...

Abstract This study presents a novel type of biopolymer patches in which anti-inflammatory drugs and amide-type anesthetics were simultaneously incorporated. Since the matrix is composed k-carrageenan, hydroxyethyl cellulose, glycerol, as plasticizer, resulting have an elasticity “stickiness” that can be exploited field transdermal delivery drugs. Combinations anesthetic resulted twenty with unique distinct physical appearance. Furthermore, indicated by FTIR, TG/DTG, DSC analysis data, none...
