Analysis of Oral Health-Related Quality of Life in Elderly Romanian Edentulous Patients: Implant-Supported Versus Conventional Complete Dentures.

Background/Objectives: The integration of quality of life (QoL) assessments into dental health evaluations acknowledges the profound impact of oral health on overall well-being. This study aims to compare the impact of implant-supported complete dentures versus conventional complete dentures on oral health-related quality of life (OHRQoL) in elderly Romanian edentulous patients. Methods: This longitudinal study involved 93 initially recruited edentulous patients, with 52 completing the study over an 18-month period. Data collection utilized the OHIP-5 questionnaire, assessing the OHRQoL at baseline with conventional dentures and three months post-implant-supported denture placement. Ethical approval was secured from the Faculty of Medicine and Pharmacy University of Oradea, adhering to the Helsinki Declaration principles. A statistical analysis was conducted using SPSS version 25 and included non-parametric tests for score comparisons and Fisher's exact test for categorical data. Results: The comparative analysis of the questionnaire responses revealed significant improvements in all five OHRQoL dimensions post-treatment with implant-supported dentures. For instance, the proportion of patients reporting "never" experiencing difficulty chewing any foods increased from 1.9% at baseline to 57.7% post-treatment. Similarly, those reporting "never" experiencing painful aching rose from 3.8% to 76.9%. There was also a notable reduction in discomfort regarding the appearance of mouth, dentures, or jaws from 3.8% reporting "never" at baseline to 75% post-treatment. The improvements in sense of taste and difficulty in performing usual activities saw comparable increases. Conclusions: The findings support the hypothesis that implant-supported complete dentures significantly enhance OHRQoL among elderly edentulous patients compared to conventional dentures, with improvements noted in mastication ability, pain reduction, aesthetics, taste perception, and activity performance. These results underscore the value of prosthetic interventions in dental care to substantially improve patients' OHRQoL.

Comparative Assessment of the Accuracy of Digital Versus Conventional Interocclusal Records in Dentulous Patients: A Systematic Review.

Interocclusal registration is an essential step in oral rehabilitation. Conventionally, interocclusal registration has been conducted using interocclusal records made of wax or silicone. However, a digital method of registration utilizing an intraoral scanner has been introduced for analyzing inter-arch relationships. This systematic review aims to compare digital interocclusal records with conventional interocclusal records by considering their respective quality, such as accuracy. A thorough search was conducted to gather relevant research from databases such as Google Scholar, PubMed, and Scopus. After evaluating the study's methodological quality assessment using NIH's Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, two independent reviewers assessed the publications for inclusion and exclusion criteria. After a methodical search, a total of five relevant papers were reviewed. The review's primary finding was that digital interocclusal records were more accurate than conventional interocclusal records.

Heat Generation and Pain Assessment in Piezosurgery Versus Conventional Drilling for Implant Placement: A Systematic Review.

The development of new technologies in implant dentistry has led to the introduction of piezosurgery, which utilizes ultrasonic vibrations for micrometric and selective bone cutting. It is hypothesized to reduce trauma to bone tissue, thereby potentially improving the healing process compared to traditional drilling methods. This systematic review examines the differences in heat generation and pain perception between piezosurgery and conventional drilling techniques for dental implant placement. An extensive review of literature was performed using various databases, includingPubMed via MEDLINE, EBSCO, and Google Scholar. Out of an initial pool of 2,279 articles, nine studies met the predefined inclusion criteria and were included in the final analysis following title and abstract screening and subsequent full-text evaluation. The quality of the selected studies was rigorously assessed using the Risk of Bias (RoB 2.0), Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I), and Quality Assessment Tool for In Vitro Studies (QUIN) tools. Data pertaining to thermal effects and postoperative pain associated with piezosurgery relative to conventional drilling protocols were collected. The results indicated a significant reduction in postoperative pain with piezosurgery; however, the technique was associated with higher intraoperative temperatures during osteotomy. These findings provide valuable insights into the potential benefits and limitations of piezosurgery in dental implant procedures.

Daily Versus Conventional Dialysis for COVID-19 Patients: A Randomized Controlled Trial

Background: Hemodialysis patients have high mortality and morbidity in COVID-19 due to different causes, thus the current study evaluates the difference between the effect of conventional and daily hemodialysis on mortality in End-Stage Renal Disease (ESRD) patients with COVID-19. Methods: This study was designed as a single-center, parallel, randomized and un-blinded clinical trial that chronic hemodialysis patients with confirmed COVID-19 infection enrolled. The study group was dialyzed daily for a week and the control group was on three sessions per week of dialysis. The primary outcome was estimation of mortality rate and secondary outcome was considered as ICU admission rate during hospitalization. Results: A total of 47 patients with the diagnosis of ESRD were included. The mean age of the included patients was 57.1±14.2 years in daily hemodialysis and 58.8±17.4 years in the conventional hemodialysis, and 36(76.6%) were male. From the 47 included patients, 18(38.3%) were admitted to the ICU, and 12(25.5%) were deceased during their hospital stay. The prevalence of the two main outcomes of the study, ICU admission and mortality, was not different between the two groups of the study. Conclusion: In this study, daily hemodialysis was beneficial in reducing mortality in COVID-19 infected patients, but this difference was not statistically significant. Studies with higher sample sizes may show this difference significantly.

Does the Timing of Orthognathic Surgery Affect the Level of External Root Resorption?: Surgery-First Approach Versus Conventional Orthognathic Surgery.

This study aimed to compare external root resorption levels, both linearly and areally, on panoramic radiographs in Class III patients whose treatment was completed with the conventional orthognathic surgery and the surgery-first approach. The study included 20 patients (10 female, 10 male; 23.98±2.63y) treated with conventional orthognathic surgery and 18 patients (8 female, 10 male; 27.5±3.42y) treated with surgery-first approach was included. Linear and area measurements were made on the digital panoramic radiographs taken before and at the end of the treatment of 38 patients who constituted the sample of the study. The mean changes observed in each group were evaluated using a paired t test. The chronological ages, skeletal features (type of Class III malocclusion), treatment durations, initial values, and mean changes that occurred in each group were compared using independent t test. When the changes in root lengths and root surface areas were evaluated in all teeth in both groups, a significant loss in size was measured (P<0.001). More resorption was observed in teeth 12 and 22 in the conventional surgery group (P<0.05). When the amount of resorption in both groups was compared, there was significantly more resorption in tooth number 12 in the conventional surgery group (P<0.05). The study showed that there was external root resorption in all teeth in both protocols, but the root lengths of the lateral teeth were shortened more in both groups.

Conventional Versus Biorational Insecticides for Controlling Mustard Aphid and Their Effects on Beneficial Insects

Mustard is one of the most important oilseed crops in Bangladesh. However, its production is severely constrained by aphid infestation. Farmers usually spray conventional insecticides to control aphids that negatively affect beneficial insects and environment. Thus, alternatives to conventional insecticides are required. We tested three biorational insecticides (Nimbicidine @ 1ml/L, Spinosad: Libsen 45SC @ 0.5 ml/L and Lufenuron: Hayron 5EC @ 0.5ml/L of water) against aphid infestation and assessed their effect on ladybird beetle and honey bee and compared these effects with two conventional insecticides (Diazinon: Sabion 60EC @ 2ml/L and Cypermethrin: Cypraplus 10EC @ 1ml/L of water) and with an untreated control. The study was conducted in a randomized complete block design with each treatment replicated thrice in the field of Department of Entomology, Bangladesh Agricultural University. Number of infested plants per plot, aphid per plant and per pod, number of ladybird beetle and honey bee per plot was counted and yield per plot was calculated. All tested insecticides reduced aphid infestation compared to untreated control indicating all of them were effective against aphid. However, Lufenuron and Nimbicidine was most effective to reduce plant infestation and number of aphids per plant and pod. Spinosad and Sabion were found fairly effective whereas Cypraplus was found to be least effective. Lufenuron and Nimbicidine did not reduce the number of ladybird beetle and honey bee visit per plot, however, Spinosad and conventional insecticides reduced their number. Lufenuron treated plots provided highest yield (1.35 t/ha) followed by Nimbicidine (1.15 t/ha), Spinosad (1.10 t/ha) and Sabion (1.00 t/ha) whereas Cypraplus treated plots provided lowest yield (0.9 t/ha). In terms of reducing aphid population thus plant infestation and increasing yield, all biorational insecticides performed better than conventional insecticides, however, concerning effect on ladybirds and honey bees, only Lufenuron and Nimbicidine can be recommended to farmers.

We Will, We Will Shock You: Adaptive Versus Conventional Functional Electrical Stimulation in Individuals Post-Stroke.

Functional electrical stimulation (FES) is often used in poststroke gait rehabilitation to address decreased walking speed, foot drop, and decreased forward propulsion. However, not all individuals experience clinically meaningful improvements in gait function with stimulation. Previous research has developed adaptive functional electrical stimulation (AFES) systems that adjust stimulation timing and amplitude at every stride to deliver optimal stimulation. The purpose of this work was to determine the effects of a novel AFES system on functional gait outcomes and compare them to the effects of the existing FES system. Twenty-four individuals with chronic poststroke hemiparesis completed 64-min walking trials on an adaptive and fixed-speed treadmill with no stimulation, stimulation from the existing FES system, and stimulation from the AFES system. There was no significant effect of stimulation condition on walking speed, peak dorsiflexion angle, or peak propulsive force. Walking speed was significantly faster and peak propulsive force was significantly larger on the adaptive treadmill (ATM) than the fixed-speed treadmill (both p < 0.0001). Dorsiflexor stimulation timing was similar between stimulation conditions, but plantarflexor stimulation timing was significantly improved with the AFES system compared to the FES system (p = 0.0059). Variability between and within subjects was substantial, and some subjects experienced clinically meaningful improvements in walking speed, peak dorsiflexion angle, and peak propulsive force. However, not all subjects experienced benefits, suggesting that further research to characterize which subjects exhibit the best instantaneous response to FES is needed to optimize poststroke gait rehabilitation using FES.

RETINAL MIGRATION AND SURGICAL OUTCOME AFTER HEMI-TEMPORAL INTERNAL LIMITING MEMBRANE PEELING VERSUS CONVENTIONAL PEELING FOR MACULAR HOLE: A Multicenter, Randomized, Controlled Trial.

To investigate the anatomical changes and surgical outcomes of hemi-temporal internal limiting membrane (ILM) peeling and conventional ILM peeling for idiopathic macular hole (MH). This randomized controlled trial was conducted at 3 centers and included 50 participants with MHs of <400 µm in minimum diameter for a duration of <6 months. All participants had undergone vitrectomy with either hemi-temporal ILM peeling (Hemi group) or 360° ILM peeling (360° group) with an injection of 5% sulfur hexafluoride gas, with or without simultaneous cataract surgery, from July 2017 to January 2021. The rate of MH closure and distance of retinal migration were examined. Of 50 eyes randomized in the 3 centers, the Hemi group comprised 23 eyes, the 360° group 23 eyes, and 4 eyes were eliminated from final analysis. There was a significantly higher rate of primary MH closure in the 360° group (Hemi group: 73.9% vs. 360° group: 100%, P = 0.009). Retinal migration to the optic disk on the nasal side was significantly shorter in the Hemi group at 1, 3, and 6 months postoperatively than in the 360° group. There was no significant difference between the two groups in retinal migration to the optic disk on the temporal side. Nasal retinal migration in patients who underwent the hemi-temporal ILM peeling method was significantly less than in those who underwent the 360° ILM peeling method. However, less nasal retinal migration did not contribute to the MH closure rate.

Comparison of the Antimicrobial Efficacy of Conventional Versus Chitosan Re-inforced Heat-Polymerized Polymethylmethacrylate Dental Material: An In Vitro Study.

Polymethylmethacrylate (PMMA) is widely used in the fabrication of dentures due to its aesthetic appeal and mechanical strength. However, PMMA's susceptibility to microbial colonization often leads to oral infections such as denture stomatitis. Enhancing the antimicrobial properties of denture materials is crucial for improving patient outcomes.Chitosan, a natural biopolymer, possesses inherent antimicrobial properties and could potentially enhance the microbial resistance of PMMA. This study has investigated thepotential of chitosan-reinforced heat-polymerized PMMA denture material to reduce microbial colonization. The aim of the study was to evaluate and assess the anti-bacterial and antifungal properties of chitosan-reinforced heat-polymerized PMMA with conventional heat-polymerized PMMA Materials and methods:Chitosan-reinforced PMMA samples were fabricated with varying chitosan concentrations (0% control, 5%, 10%, and 15% by weight). The fabrication involved mixing chitosan powder with PMMA powder, adding monomer liquid, followed by mixing, packing, and curing using the conventional heat polymerization technique. The antimicrobial efficacy was assessed in vitro using two common oral pathogens: Streptococcus mutans and Candida albicans. Blood agar plates were used for S. mutans and Sabouraud agar plates were used for C. albicans. Each sample was placed on the respective agar plates inoculated with a standardized microbial suspension and incubated at 37°C for 24 hours. The number of colony-forming units (CFUs) was counted to quantify microbial growth. Statistical analyses, including linear regression analysis, one-way ANOVA test, and Pearson correlation were performed to evaluate the relationship between chitosan concentration and antimicrobial efficacy. The p-value was calculated to determine the statistical significance of the results. The chitosan-reinforced PMMA samples showed significantly greater antimicrobial efficacy compared to the conventional PMMA samples. The CFU counts for both S. mutans and C. albicans decreased with increasing chitosan concentration. Linear regression analysis indicated a strong negative correlation between chitosan concentration and CFU counts, with Pearson correlation coefficients of -0.97 for S. mutans and -0.98 for C. albicans. ANOVA analysis revealed a statistically significant difference in antimicrobial efficacy across different chitosan concentrations (p < 0.001). Incorporating chitosan into heat-polymerized PMMA significantly enhances its antimicrobial properties against S. mutans and C. albicans. The antimicrobial efficacy improves with higher concentrations of chitosan, with the 15% chitosan-reinforced samples showing the most substantial reduction in microbial growth. These results suggest that chitosan-reinforced PMMA dentures could be a superior alternative to conventional PMMA dentures, potentially reducing denture-related infections and improving oral health outcomes for denture wearers.

The Effect of ESG Performance on the Systematic Risk of Listed Companies in China: A Comparative Analysis of High-Tech Manufacturing Versus Conventional Industries

The continued growth of the ESG (environment, society, and governance) investing trend has garnered great interest from both academics and professionals alike in the past decade. Nowadays, even developing countries like China are seeing a new wave of ESG investment opportunities. However, the research on ESG investing in emerging markets remains relatively lackluster, and fewer ESG studies concentrate on the topic of systematic risk. Therefore, this study wants to provide an analysis of the effect of ESG rating on the systematic risk of listed companies on the A-share stock market in China through the lens of a comparative study between high-tech manufacturing and conventional industries. Based on the fixed-effect model regression result on the quarterly data of 240 companies from 2018 to 2021, this paper discovers a negative correlation between ESG rating and the systematic risk a company is exposed to and a greater effect of ESG performance on systematic risk in high-tech manufacturing industries than conventional industries. Overall, this paper not only presents a new perspective on the correlation between ESG investing and the systematic risk a firm is exposed to but also serves as an inter-industry research that tackles a phenomenon specific to the Chinese capital market.

SURGICAL OUTCOMES AND INTRAOPERATIVE PARAMETERS OF THREE-DIMENSIONAL VISUALIZATION SYSTEM VERSUS CONVENTIONAL MICROSCOPES FOR MACULAR SURGERY IN HIGHLY MYOPIC EYES: A Prospective Randomized Clinical Trial.

To investigate the surgical outcomes and intraoperative parameters of 3D visualization system for macular diseases in highly myopic eyes. In this single-center, prospective, randomized, comparative interventional study, 40 highly myopic eyes (axial length > 26 mm) were randomly assigned to either a 3D visualization system or a conventional microscope group. Surgical outcomes and intraoperative parameters, including the number of indocyanine green injections, surgical time, and epiretinal membrane/internal limiting membrane peeling time, were compared. The 3D group required significantly fewer indocyanine green injections (1.3 ± 0.5 vs. 2.3 ± 0.7, P < 0.001), had shorter epiretinal membrane/internal limiting membrane peeling times (522.8 ± 258.0 vs. 751.8 ± 320.2 seconds, P < 0.05), and experienced fewer intraoperative retinal hemorrhages (0 vs. 7 cases, P < 0.05) compared with the conventional microscope group. Anatomical and functional outcomes were comparable between the two groups. The 3D system exhibited a lower number of indocyanine green injections, shorter epiretinal membrane/internal limiting membrane peeling times, and a reduced incidence of intraoperative retinal hemorrhages, suggesting the 3D visualization system may offer advantages for macular surgery in highly myopic eyes.

High Flow Nasal Cannula Versus Conventional Oxygen Therapy and Incidence of Post-Extubation Airway Obstruction in PICU: An Open-Label Randomized Controlled Trial (HiFloCOT-PICU Trial).

To study the impact of high flow nasal cannula (HFNC) vs. conventional oxygen therapy (COT) (by simple nasal cannula) as respiratory support after extubation on the rates of post-extubation airway obstruction (PEAO) among mechanically ventilated critically ill children. This open-label randomized controlled trial was conducted in pediatric intensive care unit (PICU) of a tertiary care teaching hospital in North India over a period of 7 mo (11 August 2021 to 10 March 2022). Children aged 3 mo to 12 y who required invasive mechanical ventilation for > 72h and had passed spontaneous breathing trial (ready for extubation) were enrolled and randomized by computer generated block randomization to receive HFNC or COT after extubation. Primary outcome was rate of PEAO (assessed by modified Westley croup score, mWCS) within 48h of extubation; and secondary outcomes were rate and number of adrenaline nebulization, treatment failure (requiring escalation of respiratory support), extubation failure, adverse events, and length of PICU stay in two groups. During the study period, 116 children were enrolled (58 each in HFNC and COT groups). There was no difference in rate of PEAO (55% vs. 51.7%, respectively), need of adrenaline nebulization, extubation failure, adverse events, and duration of PICU stay in two groups. However, the HFNC group had significantly lower rates of treatment failure (27.6% vs. 48.3%, p = 0.02). The rate of PEAO was similar in HFNC and COT groups. However, HFNC group had significantly lower rate of treatment failure requiring escalation of respiratory support.

In-Vitro Accuracy of Digital Versus Conventional Workflows for Complete Arch Implant Supported Frameworks - A Scoping Review.

Purpose: To investigate the available evidence on the accuracy of conventional and digital workflows for complete arch implant supported frameworks. Materials and methods: This scoping review was conducted according to the 5-stage framework of Arksey and O'Malley. A systematic literature search was performed adhering to the PRISMA guidelines to identify studies with a direct comparison of conventional and digital methods for the fabrication of complete arch implant supported frameworks. 58 in-vitro studies with the focus on edentulous arches with at least four implants published between 2000 and 2024 were included. The reported outcomes were examined to determine the value of a statistical analysis for adding up the individual errors to a cumulative error of the workflow. Results: Evidence on the accuracy assessment of digital and conventional workflows for complete arch implant supported frameworks is available. However, also studies with the same assessment methods and outcome units appear to be too heterogeneous to perform a statistical analysis of error accumulation. While there is no consensus in the impression and cast fabrication stage, digital techniques show a superior accuracy for the fabrication of complete arch implant supported frameworks compared to conventional casting. Conclusion: In-vitro studies assessing the accuracy of entire workflows and classifying their outcomes regarding the clinical relevance are lacking.
