[Candida albicans: risk factor in covid-19 patients].

Unlabelled: The Candida Albicans fungus in our body can cause various conditions and will depend directly on the systemic condition of the host. Patients with COVID-19 who have previously presented this fungus can increase the likelihood of morbidity and mortality, since this microorganism can be located in areas that correspond to the respiratory system, generating a functional deficit. If not treated timely, it will proliferate into the blood and digestive system.

Dental restoration operative time and analysis of the internal gap of conventional resins (Incremental Technique) vs. Bulk Fill (Single-Increment Technique): study.

Background: To determine the operative time and the internal restoration gap in the restoration-tooth interface in the cavity floor using an incremental technique for conventional resins and the single-increment technique for the bulk fill resin.

Material And Methods: In this experimental study, the internal gaps of the restoration-tooth interfaces in the cavity floors of two conventional resins and two bulk fill resins were microscopically analyzed, and the restoration times of the single-increment technique and the incremental technique were determined.

Results: Bulk fill resins had smaller internal gap (63.

Two possible alternatives to evaluate the effect of gastric acid on resin-based composites.

Background: Objective: To compare two protocols to study the effect of simulated gastric acid on the mechanical properties of resins based composites(RBCs).

Material And Methods: Three RBC FILTEK Supreme XTE (FS), BRILLIANT EverGlow (BE), GrandioSo (GS) were used. They were randomly divided into a control group (CG) and two groups exposed to simulated gastric acid: a 6-month daily protocol (DG) and an accelerated 90-min protocol (AG).

Accuracy of 4 digital scanning systems on prepared teeth digitally isolated from a complete dental arch.

Statement Of Problem: The accuracy of digital scanners is acceptable for scanning a complete dental arch. However, whether that accuracy is sufficient for only 1 tooth within the dental scan of a complete dental arch is unclear.

Purpose: The purpose of this in vitro study was to evaluate and compare the accuracy of 4 intraoral scanners on a complete dental arch and on prepared teeth digitally isolated from the digital scan in terms of trueness and precision.

Correction: Accuracy of four digital scanners according to scanning strategy in complete-arch impressions.

Accuracy of four digital scanners according to scanning strategy in complete-arch impressions.

Statement Of Problem: Although there are specific and general digital scanning guidelines depending on the system used, it is important to have the necessary flexibility in the acquisition of three-dimensional (3D) images to adapt to any clinical situation without affecting accuracy.

Purpose: The purpose of this in vitro study was to identify and compare the scanning strategy with the greatest accuracy, in terms of trueness and precision, of four intraoral scanners in the impression of a complete dental arch.

Material And Methods: Four digital scanners were evaluated with a 3D measuring software, using a highly accurate reference model obtained from an industrial scanner as a comparator.

Relationship between resolution and accuracy of four intraoral scanners in complete-arch impressions.

Background: The scanner does not measure the dental surface continually. Instead, it generates a point cloud, and these points are then joined to form the scanned object. This approximation will depend on the number of points generated (resolution), which can lead to low accuracy (trueness and precision) when fewer points are obtained.
