Clinical effectiveness of alkasite versus nanofilled resin composite in the restoration of occlusal carious lesions in permanent molar teeth of children: a randomized clinical trial

PurposeTo evaluate and compare the clinical effectiveness of alkasite with nanofilled resin composite restorations for occlusal caries lesions in permanent molar teeth of children, at one-year follow-up.MethodsIn this randomized controlled clinical trial with parallel design, 38 children aged 7–13 years with occlusal caries lesions on 59 first permanent molars were randomly allocated into two groups, Group 1: Filtek™ Z350XT (nanocomposite) and Group 2: Cention N® (alkasite resin composite). The restorations were evaluated at one year using the United States Public Health Service (USPHS) criteria. Data were analyzed using Chi-square or Fisher’s exact test.ResultsAll restorations had either Alpha or Bravo scores at one-year follow-up. In Group 1, all restorations scored Alpha, while one restoration each (3.6%) in Group 2 scored Bravo for fracture and marginal adaptation. All restorations in both groups scored Alpha for retention, secondary caries, and post-operative sensitivity. For anatomic form, all restorations in Group 1 scored Alpha, while three (10.7%) restorations in Group 2 had Bravo scores. For marginal discolouration, three restorations in both groups scored Bravo (11.5% and 10.7%, respectively). For surface roughness, one restoration (3.8%) in Group 1 and three restorations in Group 2 (10.7%) scored Bravo. The comparative results between the two groups for all the variables in the USPHS criteria were not statistically significantly different.ConclusionsThe performances of the nanofilled composite and alkasite were clinically acceptable and comparable. Alkasite can be an alternative material for the restoration of occlusal caries lesions in permanent molars of children.Clinical trial registrationThe clinical trial was registered at Clinical Trials Registry—India (CTRI Reg no: CTRI/2020/12/029830 Dated: 15/12/2020).

Car-Sharing Systems in Smart Cities: A Review of the Most Important Issues Related to the Functioning of the Systems in Light of the Scientific Research

Currently, short-term car rental services (car-sharing) are a solution that is an alternative to individual motorization, which can be used in cities. With the level of sophistication of the relevant systems, there are more and more problems with their proper functioning. However, to understand the essence of some of the problems or properly introduce a new system to the market, it is important to understand how the systems work and the main relationships between the factors affecting car-sharing. This work aims to comprehensively present the most important aspects related to the functioning of car-sharing in light of the current research, as a form of compendium of knowledge about car-sharing. A review of the literature indicates that the leading areas of research in the field of car-sharing are seven topics related to the origin and history of services, the analysis of the functioning of the services market and criteria affecting the development of the relevant systems, the management of vehicle systems and location, issues related to the sustainable development of transport, IT systems, electromobility in car-sharing, and service optimization and modeling. A detailed analysis of the work carried out in this area allowed for the identification of 15 leading factors influencing car-sharing. This article supports the implementation and improvement of car-sharing services. In addition, it supports researchers during literature reviews and the search for a coherent list of the factors influencing car-sharing.

Clinical comparison of different glass ionomer-based restoratives and a bulk-fill resin composite in Class I cavities: A 48-month randomized split-mouth controlled trial

ObjectiveThe aim of this study is to compare the retention rates (primary outcome) of high-viscosity glass ionomer (GI), glass carbomer (GC), zirconia-reinforced GI (ZIR), and bulk-fill (BF) composite resin restorations. Secondary outcomes included anatomical form, marginal adaptation, marginal discoloration, color match, surface texture, post-operative sensitivity and secondary caries. MethodsTwo calibrated operators placed 128 restorations in 30 patients with a mean age of 21 years. The restorations were evaluated by one examiner at baseline and at 6, 12, 18, 24, and 48 months using the modified US Public Health Service criteria. The data were statistically analyzed using Friedman test. Differences between restorations were analyzed using Kruskal–Wallis test. ResultsAfter 48 months, 23 patients and 97 restorations (23 GI, 25 GC, 24 ZIR, and 25 BF) were evaluated. Patient recall rate was 77%. No significant difference was observed between the retention rates of the restorations (p > 0.05). GC showed significantly lower results than the other three fillings in terms of anatomical form (p < 0.05). There was no significant difference in the anatomical form and retention between GI, ZIR, and BF (p > 0.05). No significant change was observed in the postoperative sensitivity or secondary caries for any of the restorations (p > 0.05). ConclusionsGC restorations showed statistically lower anatomical form values, indicating lower wear resistance than the other materials. However, no significant difference was observed in the retention rates (as primary outcome) as well as the other secondary outcomes of the four different restorative materials after 48 months. Clinical SignificanceGI-based restorative materials and BF composite resin restorations in Class I cavities yielded satisfactory clinical performance after 48 months.

The Impact of Different Bow Shapes on Large Yacht Comfort

The importance of comfort during transfer and stationing becomes a key performance parameter for large yacht design, on the same level as propulsive issues. Such a matter extends questions in terms of form and service demand to the motion behaviour of the unit in waves. Relevant studies refer to outdated hull forms not specific to modern large yachts. In this study, five hull forms with different bow concepts represent the most common design solutions for yachts at constant draught and displacement. The preliminary ranking on the effect of alternative bows on comfort requires the definition of internationally accepted comfort standards. Here, the AWI 22834 guidelines for large yachts provide the service and environmental conditions and criteria for the comfort analysis, being the only reference specific to yachts. The calculations employ a strip-theory-based numerical model to provide results of easy understanding for designers during the early design stage. The obtained ranking among the design solutions on a reference large yacht favours the option nested with a bulb, contradicting the expectations in favour of a vertical bow concept. The discussion and conclusions provide a way forward for additional analyses and investigations aimed at proposing suitable multicriterial design guidelines for large yachts. However, the results also show the unsuitability of AWI environmental and encounter conditions for hull form ranking.

A chaos opposition‐based dwarf mongoose approach for workflow scheduling in cloud

AbstractCloud computing (CC) systems are a form of public infrastructure that has been in use since its beginnings. In such technologies, clients can access current services according to their requirements without knowing where the service is hosted or how it is supplied, and only pay for the services that they really consume. The CC system faces several challenges. Due to the large range of clients and services offered by this platform, it can be concluded that the scheduling problem and resource usage are its primary issues. In order to successfully balance the three main qualities of service (QoS) criteria: time, cost, and resource usage, researchers were inspired to improve the workflow scheduling (WFS) methods in cloud. Since the randomness of the initial population and the inadequate exploration/exploitation capacity, which has an impact on the quality of the solutions, traditional intelligent optimization algorithms have a poor convergence rate when it comes to resource scheduling. In this research, we suggested a hybridization method combining the Dwarf Mongoose algorithm (DWO) and Chaos opposition based learning algorithm called CO‐DWO in an attempt to develop a more effective optimization algorithm for workflow scheduling issue. The CO‐DWO can be much more advantageous in optimization with a better convergence rate in comparison with other literature techniques.

Abstract 133: Over Estimation Of Percent Stenosis By Physician Operators May Lead To Carotid Stent Over Utilization

Introduction: Based largely on the inclusion criteria of clinical trials, the degree of cervical carotid artery stenosis is often used as an indication for stent placement in the setting of carotid atherosclerotic disease. However, the rigor and consistency with which such stenosis is measured outside of clinical trials is unclear. We compared the percent stenosis as measured by real world physician operators to that measured by independent expert reviewers. Hypothesis: We hypothesized that the documented degree of stenosis, termed operator-reported stenosis (ORS), from real world facilities performing carotid stent placement would be larger than the reviewer-measured stenosis (RMS) as assessed by clinicians experienced in treating carotid artery disease. Methods: Images were selected from patient cases used for carotid stenting facility accreditation. Data collected included demographics, National Institutes of Health Stroke Scale, modified Rankin Score, and the documented degree of stenosis (ORS). The ORS was compared to the RMS, derived from a panel of expert clinicians. Results: A total of 68 angiograms were reviewed from 39 symptomatic and 29 asymptomatic patients. The RMS values demonstrated excellent agreement with an intra-class correlation of 0.80. The median ORS was 90.0% (IQR 80.0, 90.0) versus a median RMS of 61.1% (IQR 49.8, 73.6), with a median difference of 21.8% (IQR 13.7, 34.4), p &lt; 0.001. This discrepancy persisted within several subpopulations and was larger among asymptomatic patients and those treated at facilities granted delayed accreditation. Based on RMS values, 72% of symptomatic patients and only 10% of asymptomatic patients would meet the Centers for Medicare and Medicaid Services criteria for carotid stent placement. Conclusions: Real world operators tend to overestimate cervical carotid artery stenosis compared to external expert reviewers. Since decisions regarding carotid revascularization are often based at least partially on percent stenosis, such measuring discrepancies inevitably lead to a higher volume of procedures, which may in turn represent a degree of procedural over utilization.

Porcelain Veneers in Vital vs. Non-Vital Teeth: A Retrospective Clinical Evaluation.

Nowadays, the ceramic veneer approach can be considered more predictable than direct composite veneer. To date, there is a lack of studies comparing the clinical performance of anterior veneers cemented on vital teeth (VT) and non-vital teeth (NVT). This longitudinal clinical study investigated the performance of ceramic veneers in VT or anterior NVT. A total of 55 patients were evaluated in the study. Two groups were defined based on the vitality status of the teeth (93 teeth-vital and 61 teeth-non-vital). The United States Public Health Service (USPHS) criteria were used to assess the clinical status. The data were evaluated statistically with the Mann-Whitney U test. All restorations were considered acceptable, and only one veneer in VT failed for the criteria of secondary caries. There were no statistically significant differences in any of the criteria evaluated (p ≤ 0.671). The ceramic veneers evaluated showed a satisfactory clinical performance both in VT and NVT.

ANALYTICAL HIERARCHY PROCESS AND TOPSIS APPROACH TO PERFORM SUPPLIER SELECTION IN CONSTRUCTION INDUSTRY

&lt;p&gt;&lt;em&gt;Suppliers play an important role as suppliers of production raw materials, making companies must choose suppliers correctly. This paper discusses the best supplier selection to avoid financial and non-financial losses This paper uses four criteria for determining the best supplier, such as price, lead time, payment terms, and quality &amp;amp; service. A reasonable price following initial planning is always expected by the customers. Lead time is an essential consideration to ensure on-time delivery. Failure to perform on-time delivery will direct in poor payment terms. Besides, any products that do not meet quality standards will always lead to waste. Analytical Hierarchy Process (AHP) and Technique Order Preference by Similarity to Ideal Solution (TOPSIS) are used to select and determine the best supplier for the company. Pairwise comparisons are performed by making comparisons between each criterion and the alternatives made at each level of the hierarchy in pairs to get the value of the importance of the elements in the form of a qualitative opinion. The weight values for price, lead time, payment terms, and quality and service criteria are 0.0709, 0.1409, 0.2682, and 0.5200, respectively. According to AHP, alternative weight values in each criterion are 0.3899, 0.3063, and 0.3038, namely supplier A (rank 1), supplier B (rank 2), and supplier C (rank 3), respectively. However, the results of supplier selection using the TOPSIS method are supplier B (rank 1), supplier C (rank 2), and supplier A (rank 3) with values of 518.4025, 469.2017, and 412.3928, respectively.&lt;/em&gt;&lt;/p&gt;

12 Month's Assessment Of Clinical Efficacy Of Resin Modified Glass Ionomer Cement And Flowable Composites In Restoration Of Non-Carious Cervical Lesions, A Randomized Clinical Trial.

The objective of this study was to compare the clinical efficacy of Resin modified glass ionomer cement and Flowable composite in terms of retention, marginal adaptation and surface texture using United States Public Health Service criteria in non-carious cervical lesions measured over a period of one year. A Randomized Clinical Trial is conducted with Informed consent on 60 patients who are randomly allocated into 2 groups with at least 2 Non Carious Cervical Lesions in each. Group 1 is used for Flowable Composite while group 2 is used for resin modified glass ionomer cement. A recall is maintained to draw conclusions between two materials in terms of occurrence of marginal adaptation, retention and surface texture, to show which material is superior to other. Out of 30 restorations in 12 months follow up, only 19 found to be present in flowable composite group while in resin modified glass ionomer cement group, 28 are retained. Regarding margin integrity, Group 1 showed 21 intact margins whereas 23 margins were intact in group 2, while 18 and 25 showed smooth surface in flowable composite and Resin modified glass ionomer cement group respectively, on exploration. It can be concluded from our study that Resin modified glass ionomer cement is superior to Flowable composite in terms of retention (p=0.005) and surface texture (p=0.045) in restoration of non carious cervical lesion.

One Year Clinical Evaluation Of Translucent Zirconia Crowns In Dental Esthetic Zone With Biologically Oriented Preparation Technique Versus Conventional Preparation (RCT)

Statement of the problem: Tooth preparation with horizontal finish line requires removal of reasonable amount of tooth structure at the cervical area which affects the remaining tooth structure at this area. Therefore, more conservative preparation design such as biologically oriented preparation technique (BOPT) might be needed to save tooth structure at the cervical area. The Purpose: To Evaluate the effect of Conventional preparation design (horizontal), and Biologically Oriented Preparation Technique (BOPT), on Marginal adaptation, fracture and gingival inflammation score of the translucent zirconia crown in dental esthetic zone. Methodology:, 44 monolithic translucent zirconia single crowns were fabricated inn dental esthetic zone . The patients were separated randomly into two groups. Group1: (horizontal preparation design) Group2: BOPT. After final cementation. The Modified United States Public Health Service (MUSPH) criteria for restoration clinical evaluations were used to assess marginal adaption. Gingival inflammation was assessed using gingival inflammation index. Evaluation of the restoration was at intervals of three, six, nine, and twelve months. Results: Comparison between two groups at different intervals regarding marginal adaptation, fracture and gingival inflammation score revealed statistically insignificant difference. Conclusions: Within limitations of the present one year follow up randomized clinical trial, the following conclusions could be drawn: 1.The conventional and BOPT preparation designs both clinically accepted to provide successful dental restoration The lower gingival inflammation score of the restored teeth with the conventional preparation design compared to that of the BOPT, may not be conclusive as regard the study time frame, indicating that increasing the follow-up period might alter the present finding. Clinical implications: Beyond of all the prosthodontic preparation techniques, knowledge of B.O.P.T. (Biological Oriented Preparation Technique) allows us to achieve predictable and consistent results in terms of periodontal health and gingiva architecture surrounding ceramic restoration. Nevertheless, long term studies are necessary to ensure the benefits of this techniques.

Knowledge, Attitude and Associated Factors Toward Ethiopian Abortion Law Among Reproductive Age Women in Bule Hora Town, Southern Oromia, Ethiopia, 2022.

A woman's health and wellbeing are impacted by illegal abortion since improper procedures can lead to consequences like extreme bleeding, infection, and damage to the reproductive organs and low awareness and attitude toward abortion law is one of the public health problems in Ethiopia. This study aimed to assess the knowledge, and attitude, and identify the effect of short birth interval and wealth index on the abortion law among reproductive-age women in Bule Hora town, Southern Oromia, Ethiopia. A community-based cross-sectional study design was conducted from June 20 to July 20, 2022. A systematic random sampling technique was carried out to select 402 reproductive-age women. Data was collected by using a structured questionnaire with face-to-face interviews after the tools were pretested. The data was cleaned, coded, and entered into Epidata 3.1 and exported to STATA 14 for analysis. The model goodness of fit was checked using the Hosmer-Lemeshow test. Statistical significance is declared at P < .05 and a 95% confidence interval. The study revealed that 153 (38%) of respondents had good knowledge and 192 (47%) had a favorable attitude toward the Ethiopian abortion law, with a 100% response rate. Women's educational status, having information regarding the criteria of legal abortion services, and short birth intervals as a reason for induced abortion were significantly associated with knowledge. On the other hand, women who attended secondary education and above, have information regarding the criteria of legal abortion services, wealth index middle/average and richer, using the contraceptive method, and short birth interval as a reason for induced abortion were predictors of attitude toward Ethiopian abortion law. This study shows that knowledge and attitude toward Ethiopian abortion law was not sufficient. So focusing on awareness creation and health education strategies by mobilization of the community to minimize the knowledge and attitude gap is essential.

Impact of policy changes of Medicare-rebated telehealth services on medical abortions provided at a family planning service during the coronavirus (COVID-19) pandemic.

This study reviewed data on the mode of delivery of medical abortion care (via face-to-face or telehealth) at a Family Planning service during the coronavirus (COVID-19) pandemic; April 2020 to March 2022. This was considered over time, in the context of changing eligibility criteria for Medicare-rebated telehealth services as well as patient demographic data. The study demonstrated that when Medicare rebates for telehealth are available for all those requiring abortion care, telehealth contributes to care provision alongside face-to-face services, and is more likely to be utilised by people living in regional and remote areas.

Evaluation of remineralizing effect of zinc-carbonate hydroxyapatite on the reduction of postrestorative sensitivity: A randomized controlled clinical trial.

The adhesive bonding ability of composite resins makes it unnecessary to remove tooth structure for retention, prevention, and convenience. However, postoperative sensitivity after placing composite restoration has been a significant problem experienced by clinicians. The present randomized controlled trial was conducted to assess the role of dentin remineralization in the reduction of postoperative sensitivity after composite placement. Eighty participants with occlusal carious teeth were randomly allocated to one of the four study groups, each having 20 participants, and are as follows: Group A with test group, Group A with control group, Group B with test group, and Group B with control group. Postoperative sensitivity was assessed using the Visual Analog Scale (VAS) and the United States Public Health Service (USPHS) criteria at different time intervals such as baseline, 1 week, 1 month, and 3 months. Data were analyzed using the Kruskal-Wallis ANOVA test, Mann-Whitney U-test, and Wilcoxon matched-pair test. All 80 participants were analyzed at the baseline, 1 week, 1 month, and the end of 3 months for the postoperative sensitivity using the VAS score and USPHS criteria. One restoration in Group A with control group reported mild sensitivity at the end of 1 week and one restoration in Group B with control group reported severe sensitivity at the end of 3 months, necessitating its replacement followed by root canal treatment. No relationship was reported between postoperative sensitivity and tooth type. There was no statistically significant difference in postoperative sensitivity in any of the treatment modalities. Class I restoration using self-etch or selective-etch as well as with or without zinc-carbonate hydroxyapatite is a viable and predictable solution for the reduction of postoperative sensitivity if all the aspects of restorative techniques are considered precisely.

An Enhanced MCDM Model for Cloud Service Provider Selection

Multi-Criteria Decision-Making (MCDM) techniques are often used to aid decision-makers in selecting the best alternative among several options. However, these systems have issues, including the Rank Reversal Problem (RRP) and decision-making ambiguity. This study aimed to propose a selection model for a Cloud Service Provider (CSP) that addresses these issues. This research used the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to rank the alternatives. The entropy technique is utilized to determine the weight of the criteria, and Single Valued Neutrosophic (SVN) is employed to address uncertainty. To select the best cloud provider based on Quality of Service (QoS) criteria, we used a dataset from Cloud Harmony for this study. The results indicated that the suggested model could effectively resolve the RRP under conditions of uncertainty. This research is novel and is the first to address both the problem of uncertainty in decision-making and RRP in MCDM.

Clinical evaluation of complete digital workflow ceramic overlays in treatment of children with molar incisor hypomineralization

Pediatric dentists frequently encounter challenges in management of first permanent molars with molar incisor hypomineralization (MIH). They are found to have posteruptive breakdowns, active growth phase, inconclusive occlusal contacts, and wide pulp chambers with prominent pulp horns. The previous led to poor compliance, defective anesthesia, and restoration adhesion problems.ObjectivesEvaluate clinically indirect lithium disilicate glass–ceramic overlay versus indirect composite resin overlay using complete digital workflow in treatment of permanent molars with MIH in children.Patients and methodsThis split mouth randomized clinical trial compared full digital workflow lithium disilicate glass–ceramic overlay in comparison with the same workflow indirect computer aided design-computer aided manufacturing resin overlay in treatment of MIH molars in 12 children aged between 8 and 13 years with total of 24 first permanent molars into two groups. These MIH vital molars fell in the array of index 2 and 4 upon which the entire carious and hypomineralized enamel was removed with uniform reduction with final shoulder margin on sound enamel to receive the overlays.ResultsBoth groups were assessed according to United States Public Health Services criteria of evaluation on 3 months interval for 9 months where the lithium disilicate glass ceramic overlay group showed 100% cumulative survival rate with consistent retention and anatomic form results as well as complete absence of pain and hypersensitivity at 9 months. No significant difference between both groups except for the anatomic form in which significant difference was found in favor of the lithium disilicate glass–ceramic group.ConclusionOverlays serve as esthetic, conservative and long-term treatment option with digital dentistry incorporation in every aspect of dentistry nowadays to provide accurate and quick delivery of the restorations with both groups behaved in a clinically acceptable performance.

The clinical success of ART restorations and Hall technique in primary molars: a randomized 18-month follow-up study.

The aim of the study was to evaluate the clinical and radiographic success of the Hall technique (HT) and atraumatic restorative treatment (ART) restorations using high-viscosity glass-ionomer cement for the management of occlusal carious lesions in primary molars. This randomized clinical study observed 40 children (aged 5-6 years). For each child, one tooth was treated with HT and one with ART. The primary outcome measures for HT restorations were successful, minor, and major failure rates. Clinical evaluations of ART restorations were performed according to the modified United States Public Health Service criteria during 18-month follow-up. McNemar test was used for statistical analysis. Thirty of 40 (75%) participants returned for 18 months of follow-up. In the clinical evaluations of teeth that were treated with HT, the patients did not have complaints of pain or other symptoms, all crowns remained in the oral cavity, the gums were healthy, and the teeth were functional in all evaluations. At the end of the 18-month follow-up, the surface texture and marginal integrity criteria of ART restorations were recorded as 26.7% and 33.3%, respectively. In the radiographic evaluation of 30 patients treated with ART and HT, all restorations were considered successful. The 18-month clinical and radiographic results after treatments applied to single-surface cavities in anxious children showed that both treatment methods were successful.

Influence of technical quality and coronal restoration on periapical health of root canal treatment performed by Malaysian undergraduate students

Introduction: Root canal treatment (RCT) and its coronal restoration should be regularly assessed to ensure a successful treatment outcome. The aim of the current study is to evaluate the relationship between the obturation technical quality and coronal restoration in the clinical and radiographic outcome of RCT provided by Malaysian undergraduate students. Materials and Methods: A total of 143 root-treated teeth from 136 patients were evaluated through clinical examinations and periapical radiographs with a mean follow-up period of 2.4 (standard deviation = 1.59) years. The quality of the coronal restoration was classified according to modified United States Public Health Service criteria and the technical quality of the obturation was assessed based on two variables: length and density. Periapical status was evaluated according to periapical index scores. Results: About 64% of the teeth were classified as healthy with a significant reduction of apical periodontitis from 70.3% preoperatively to 36% at reassessment (P &lt; 0.001). About 92.1% of obturation was of acceptable length, whereas 5% underfilled and 2.9% overfilled. Teeth with acceptable obturation length were five times less likely associated with apical periodontitis than the inadequately filled ones. 90% of canals had adequate obturation density with no significant association to apical periodontitis. Teeth restored with intracoronal restorations had 50% more chance of developing apical periodontitis. Inadequately restored teeth and teeth with poor obturation quality were associated with three times more likely apical periodontitis occurrence. The quality of endodontic treatment and the coronal restoration significantly influenced the periapical status (P &lt; 0.001). Conclusion: The radiographic obturation quality and coronal restorations of the RCTs performed by the undergraduate students in a Malaysian public dental school were acceptable in 63.8% of cases with a 64% favorable outcome.

영국의 장애판정제도와 정책적 시사점

This study aimed to explore the UK’s disability assessment system in depth and derive its policy implications for Korea. Disability assessment is the process of determining who has the qualification to receive social welfare benefits and services. Thus, this study especially focuses on income security, employment and social service policies, which are the core areas of welfare policies for the disabled. In addition, through a comparative analysis with the UK, the problems of Korea's disability assessment system were discussed and following recommendations were presented. First, we need to move away from the limited categories of disability and expand the range of beneficiary criteria of the disabled based on their difficulties and needs. Second, it is necessary to develop disability evaluation standards and methods that are suitable for the purpose of policies and services. Third, eligibility criteria of disability pension should be focused on work capacity of the disabled rather than medical impairment condition. Eligibility criteria of social care services also should be evaluated by needs and functional limitation of disabled people in real life. Fourth, disability assessment requires a multidisciplinary approach and various professional manpower, information, and qualitative evaluation should be implemented.
