The Effectiveness of Conventional and Advanced Aligning Archwires: The Insights of Two Randomized Clinical Trials

Abstract Objectives This study aimed to compare the clinical effectiveness of four aligning archwires: Superelastic Nickel-Titanium (Superelastic-NiTi), SmartArch, Copper-Nickel-Titanium (Cu-NiTi), and Speed Tubular coaxial-Nickel-Titanium (Tubular coaxial-NiTi), regarding the alignment efficiency, associated perception of pain, and possibility of inducing root resorption. Materials and Methods This study includes two randomized clinical trials run in parallel. Patients with 5 to 9 mm of mandibular anterior teeth crowding according to Little's irregularity index (LII) who needed fixed orthodontic appliances without extraction were randomly assigned to four groups of aligning archwires (each trial with two groups): 0.014-inch, 0.018-inch Superelastic-NiTi; 0.016-inch SmartArch; 0.014-inch, 0.018-inch Cu-NiTi; and 0.016-inch, 0.018-inch Tubular coaxial-NiTi. LII was measured pretreatment and every 4 weeks for the next 16 weeks. Pain perception was assessed using a visual analogue scale in the first 7 days after the placement of each archwire. Periapical radiographs for mandibular central incisors were taken pretreatment and after 16 weeks to assess root resorption. The alignment efficiency was tested using a repeated measures analysis of variance test with mixed factorial design (between and within-subject effect), while pain perception and root resorption were tested using the Kruskal–Wallis test and Wilcoxon signed-rank test. Results A total of 73 patients were recruited from different centers. The analysis included 64 patients who completed the trials. Neither clinical nor statistical significance was found between the groups regarding the alignment. Similarly, there was no significant difference between the four groups regarding pain perception and root resorption. However, root resorption was slightly more in the Superelastic-NiTi group than in the other groups. Limitations The short time that root resorption was reported. Conclusions The four types of archwires performed comparably regarding the alignment efficiency, associated perception of pain, and the possibility of inducing root resorption. Registration The trials included in this study were registered with ClinicalTrials.gov on May 26, 2022 (Registration number: NCT05391542) and August 18, 2022 (Registration number: NCT05510206).

AbstractInhalation of Staphylococcal Enterotoxin B (SEB) is known to induce acute lung injury (ALI) and studies from our laboratory have shown that THC, a psychoactive ingredient found in Cannabis sativa, can attenuate the ALI. In the current study, we investigated the role played by lung microbiota in ALI with or without THC treatment. A dual-dose of SEB was given to C3H/HeJ mice, which were then treated either with vehicle or THC. SEB-administration caused ALI and 100% mortality while all THC-treated mice survived and suppressed the inflammation in the lungs. Furthermore, lung microbiota was collected and 16S rRNA sequencing was performed. The data were analyzed to determine the alpha and b ... Show More

Objective(s): The aims of present study to findout the effect of aeromedical evacuation program on flight medics’ knowledge.
Methods: A pre-experimental design is carried in army aviation bases in Iraq, for the period of April 1st 2019 to October 25th 2019. Non-probability "purposive" sample of (30) flight medics are selected from army aviation bases. The questionnaire consisted of two main parts: the demographic characteristics of air paramedics, and the second part included five axes, which are (50) paragraphs related to the knowledge of air paramedics towards emergency injuries. The researcher used the statistical program version 20 to analyze the data, and the stability of the questionnaire was measured through the pre and post

This study presents a detailed morphology and taxonomic study of Polysiphonia subtilissima collected from Abdul Rehman Goth, Karachi coast, Pakistan. Polysiphonia is a filamentous heterotrichous red algae, characterized by its branching structures and attachment mechanisms. P. subtilissima is notable for its broad salinity tolerance and wide distribution across marine and freshwater ecosystems. This research provides an in-depth examination of the internal and external structures of P. subtilissima, contributing to its systematic study and documenting its first recorded occurrence in Pakistani coastal areas, bordering the northern Arabian Sea. The findings enhance the understanding of the species taxonomy and its ecological role in
