The Bond Strength of Orthodontic Resins to Porcelain
Authors: White Gregory J. , Tyas Martin J. 
Published: January 2024

Abstract
Orthodontic brackets were bonded to one of two porcelain surfaces using a self-cured or one of two light-activated orthodontic bonding resins. The porcelain surfaces were either glazed (control) or de-glazed (experimental) by being subjected to either 1.23% APF for 4 minutes or roughened with a Busch silent wheel. The bonds were tested to failure in shear mode on a universal mechanical testing machine. For one porcelain, there was no significant difference in the mean bond strengths between the control and the APF-treated surface, but for the second porcelain the mean bond strength was significantly greater when the surface was de-glazed by abrasion. It is considered that the mean bond strengths may be inadequate to withstand manipulations associated with routine orthodontic therapy.
Computers and the Orthodontist

Published: January 2024

Abstract
Dentofacial Planner Plus (DFP) is a computerised cephalometric program that enables rapid and accurate analysis of a cephalogram to aid in treatment planning. In addition, a video image of a patient’s profile can be linked to the digitised cephalogram. Manipulation of the tracing will produce corresponding changes in the video image. Simulations of orthodontic treatment or orthognathic surgery changes are therefore possible. This becomes a valuable aid in treatment planning, communication with the oral surgeon and patient education.

Abstract
This paper constitutes a new technological solution for the exploitation of one of the most important geothermal deposits located in the locality of Biskra (South-east Algeria). This is the Albian aquifer whose hot waters from boreholes, hot springs and spas are poorly exploited while ambient temperatures during winter periods reach very low levels, especially at night. The principle of this geothermal system is to immerse a PVC tubular water-air exchanger in a pool permanently supplied with hot water from a low-energy geothermal borehole with a high flow rate. The choice of PVC material is attributed to the fact that hot geothermal waters are generally of an aggressive composition to steels and metals in general. The geothermal air heater allows the heating of the ambient cold air which is introduced into the exchanger and then extracted hot using an extraction fan. The hot air is then diffused into premises for heating during the winter season. The improvement in the performance of this type of exchanger is highlighted, in particular by acting on the number of pipes of the exchanger and the air flow rate using geothermal energy (low energy) as a source of renewable and clean energy. The experimental results obtained showed that the energy gain is a function of the length of the exchanger and the air flow rate. This gain can be up to 20°C between the inlet and outlet of the miniature exchanger model, which means that the proposed solution could be technically feasible.

Authors: Setianingtyas Prastiwi , Laras Ayuningrum Dwi 
Published: January 2024

Background: Taurodonsia is a dental anomaly that undergoes vertical dilation of the pulp chamber and has a short root. Teeth with taurodonsia affected by caries to the pulp must be treated endodontically first before restoration. Case Report: a 4-year-old girl came in complaining of cavities in her lower jaw. After clinical examination, 84 teeth experienced deep dentin caries and from the results of radiographic photos, it was found that caries was almost close to the pulp horn with a large pulp chamber and short roots. The endodontic treatment carried out is pulpotomy and after that the final restoration uses a stainless steel crown. Conclusion: Taurodontia is a rare occurrence that requires a thorough clinical and radiographic examination to aid diagnosis and appropriate treatment planning. Pulpotomy can be an endodontic treatment option for primary teeth experiencing taurodontia based on objective and subjective considerations of the patient's condition

Published: January 2024

Introduction: Removable dentures are either whole or partial. Fixed dentures are firmly affixed to the patient's teeth. Dentures reduce functional problems caused by tooth loss, but many individuals don't realize how crucial cleaning them is. Long-term denture use can hinder the tongue and saliva's cleaning of the dental mucosa. Thus, Candida albicans cling better to denture bases and primary agen in candidiasis oral. Aloe vera leaves contain six antimicrobial compounds that prevent the growth of various fungi, bacteria, and viruses, including Candida albicans and Staphylococcus pyogen. Objective: Knowing the effect of aloe vera extract (Aloe vera) with a concentration. Methods: The research method is True Experimental Laboratory, which uses a research design in post-test-only control groups. The Kruskal-Wallis test was used to analyze and interpret the research data results, and the Mann-Whitney U test was used as a follow-up analysis. Results: The normality test results showed a p-value of 0.033 in the control group of aquades smaller than 0.05. This proves that the control equates are generally not distributed because the p-value is smaller than 0.05 (p-value 0. The p-value 0.05 was obtained in the control group, proving that the control group is normally distributed. In the homogeneity test, a p-value of 0.000, smaller than 0.05, is obtained. This proves that the test data results in the control and treatment groups are not homogeneous. Conclus inhibits the development of Candida albicans in heat-cured acrylic resin.

Published: January 2024

Conventional aircraft sizing methods face challenges in analyzing all-electric or hybrid-electric novel aircraft configurations, such as those for urban air mobility applications. The vast design space containing both continuous and discrete design variables and competing design objectives necessitates searching for not necessarily a unique optimal design but rather an array of Pareto-optimal designs. This paper uses the Parametric Energy-Based Aircraft Configuration Evaluator, an aircraft sizing framework for novel aircraft and propulsion system architectures, to pursue multi-objective optimization of a lift-plus-cruise urban air mobility aircraft with all-electric, hybrid-electric, and turbo-electric propulsion system architectures using Nondominated Sorting Genetic Algorithm II. The optimization cases considered include multiple objective functions, such as maximum takeoff mass, mission time, energy and propulsion mass fraction, and energy used per unit distance per unit payload. Optimization was performed for trip distances of 80, 120, and 150 km and battery specific energy levels of 350 and 400 Wh/kg. Except when mission time was an objective function, Pareto-optimal designs occurred near the lower bound of the velocity range. Raising that bound had an impact on the architectural composition of the final generation. All-electric architectures appeared exclusively for lower trip distances, hybrid-electric designs appeared for longer trip distances, and turbo-electric designs only appeared for combinations of longer trip distances, a higher minimum cruise speed, and a lower battery specific energy level. The sizing results were sensitive to assumptions regarding the overload capacity of lift propulsor motors in postfailure conditions.

Published: January 2024

Atrial fibrillation is a rhythm disorder with an extensive etiology and not fully understood pathogenesis. Catheter ablation is an effective way to control the rhythm of atrial fibrillation. The results of catheter ablation differ in patients with various comorbidities of the cardiovascular system. Intraoperative changes in the atrial rhythm can be a criterion for the long-term effectiveness of the operation or determine the need for additional effects.Aim: To assess intraoperative changes in atrial rhythm during catheter ablation of atrial fibrillation in patients with concomitant pathology of the cardiovascular system.Methodology and research methods. The results of catheter ablation of 451 patients with paroxysmal and persistent atrial fibrillation were analyzed retrospectively for the period from 2016 to 2017. After clinical and anamnestic data analysis, 151 patients with primary isolation of the pulmonary veins were selected. Depending on the concomitant pathology of the cardiovascular system, patients were divided into 3 groups: group 1 – with idiopathic atrial fibrillation, group 2 – atrial fibrillation in combination with isolated essential arterial hypertension and group 3 – atrial fibrillation in combination with ischemic heart disease.Results. In patients with idiopathic atrial fibrillation, relief of atrial fibrillation with sinus rhythm preservation until the end of surgery was more often observed than in patients with ischemic heart disease (22% vs. 10,6%, р = 0,021). In patients with ischemic heart disease, typical atrial flutter was much more common and there was a need to perform radiofrequency ablation of the cavothricuspid isthmus in addition to isolation of the pulmonary veins (47,9% vs. 18,8% 1 Group 1, р = 0,005, and 24,7% in Group 2, р = 0,01).Conclusions. The concomitant pathology of the cardiovascular system in patients affects the dynamics of the atrial rhythm during catheter treatment of atrial fibrillation and may take into account the definition of intraoperative tactics.
