AI Article Synopsis
- The study aimed to assess how the location of dental arches and scanning methods affect the accuracy, duration, and number of images taken during complete-arch implant scans with an intraoral scanner.
- Key findings indicated that the maxillary scans had lower accuracy and required more time and images compared to mandibular scans, while the circumferential scanning method yielded the best overall results for accuracy and efficiency.
- It was concluded that both the position of the dental arch and the chosen scanning pattern significantly impact the effectiveness of intraoral scanning.
Article Abstract
Objectives: To measure the influence of arch location and scanning pattern on the accuracy, scanning time, and number of photograms of complete-arch implant scans acquired using an intraoral scanner (IOS).
Materials And Methods: A maxillary (maxillary group) and mandibular (mandibular group) model with 6 implant abutments on each cast was digitized using a desktop scanner (control scans). Six subgroups were created based on the scanning pattern used to acquire the scans using an IOS (Trios 4): occluso-buccal-lingual (OBL subgroup), occluso-linguo-buccal (OLB subgroup), bucco-linguo-occlusal (BLO subgroup), linguo-buccal-occlusal (LBO subgroup), zigzag (ZZ subgroup), and circumferential (C subgroup). The control scans were used as a reference to measure the discrepancy with the experimental scans calculating the root mean square error. Two-way ANOVA and the pairwise comparison Tukey tests were used to analyze the data (α = .05).
Results: Significant discrepancies in trueness (p < .001), precision (p < .001), scanning time (p < .001), and number of photograms (p < .001) were found. The maxillary group obtained poorer trueness and precision values, higher scanning times, and a larger number of photograms than the mandibular group. The C subgroup obtained the best trueness and precision values, but was not significantly different from the OLB, BLO, and LBO subgroups. The ZZ subgroup obtained the worst trueness and precision values (p < .05). The C subgroup obtained the lowest scanning time and number of photograms (p < .05).
Conclusions: Arch location and scanning pattern influenced scanning accuracy, scanning time, and number of photograms of complete-arch implant scans.

Purpose: This study examined the occurrence and MRI characteristics of perinatal arterial ischemic stroke (PAIS) in children with cerebral palsy (CP) and suspected term hypoxic-ischemic injury (HII).
Methods: A retrospective review of brain MRI scans was conducted on children with CP and suspected term HII in South Africa.

The present study demonstrates the significance of the C/N ratio and double helical ribbon (DHR) impeller in the anaerobic co-digestion (AnCo-D) of sugar refining process (SRP) effluent and molasses-based distillery spent wash (DSW) for improved biogas production. Both SRP & DSW were mixed in different percentages to achieve an optimum C/N ratio. Further biomethane potential analysis of mixed feeds with different C/N ratios was performed.

Hematite (α-FeO) nanoparticles have been synthesized from waste source of iron which contains a prominent amount of iron (93.2 %) and investigated the effect of low temperature calcination. The two-step synthesis method involved preparing ferrous sulfate through acid leaching process followed by oxidation and calcination at temperatures ranging from 200 to 400 °C to produce the desired α-FeO in nano form.

In this research work, four distinct WO electrodes were synthesized and coated with three different polymers, known as polypyrrole (PPy), poly(3,4-ethylenedioxythiophene) in poly(4-styrenesulfonate) (PEDOT:PSS) and polyaniline (PANi), using electropolymerization techniques. The morphological features of the samples were thoroughly characterized through Field Emission Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM) analyses. Additionally, contact angle measurements and electrochemical characterizations were used to verify the performance of each electrode, aiding in the prediction of their suitability for energy storage applications in lithium-ion batteries.

Rationale And Objective: The visualization of soft tissues, like the meniscus, through X-ray micro-computed tomography (micro-CT), requires the use of contrast agents (CAs). While other studies have investigated CA diffusion in fibrocartilagineous tissues, this work aimed to optimize iodine staining protocols for meniscal tissue that improve their visualization by micro-CT. Specific objectives included evaluating the diffusion of CAs within meniscal samples over time, assessing volume changes due to staining, and identifying the iodine ions absorbed by the tissue.
