Abstract Background Bruxism is defined as repetitive jaw-muscle activity characterized by the grinding and clenching of teeth. The prevalence of bruxism in children is extensive, and it can cause irregularities in dental arches. The study aimed to investigate the presence of any effects of bruxism on maxillary arch length and width in children using three-dimensional (3D) digital model analysis. Method This study evaluated 30 children with bruxism. For every child with bruxism, a case control without bruxism was selected and matched for gender, age, and dentition. Digital models of the patients’ maxilla were obtained with a 3D intraoral scanner, and width and length measurements between the reference points on the maxilla were obtained on the digital models. Results The mean age of the study group was 9.13 ± 1.27. Insıgnificance differences were found between females and males within and between groups in terms of maxillary width and length. Insignificant difference was found between the control and study groups when the lengths of 3R-3L, 4R-4L, 5R-5L, 6R-6L, and IP-M were compared (p > 0.05). Conclusion Based on the study results, there were no differences in the maxillary arch length and width in patients with bruxism and patients without bruxism.

Abstract Introduction Percutaneous vertebroplasty has been used for treatment of intractable painful fractures of vertebral bodies. With the help of refined procedures and standard techniques, the interventional radiologist can now offer help to orthopedics and neurosurgeons in these cases, which include treatment of vertebral compression fracture. Vertebroplasty is aimed at reducing the pain induced by collapse. Vertebroplasty is the standard mode of treatment for vertebral collapse, and in our study, bipedicular vertebroplasty was compared with unipedicular approach as bipedicular vertebroplasty is the routinely used approach. Aim To compare efficacy of unipedicular percutaneous vertebroplasty with that of bipedicular percutaneous vertebroplasty. Material and Methods A total of 52 vertebroplasties were done over a period of 2 years. Out of 52 patients, 28 patients underwent unipedicular vertebroplasty and 24 patients underwent bipedicular vertebroplasty. Visual analogue scale (VAS) scores were used to assess the pain prior to vertebroplasty and after vertebroplasty. Efficacy of the two procedures were assessed by comparing VAS scores. Results There was no statistically significant difference observed in the preprocedure and postprocedure VAS scores (p-value < 0.0001, < 0.0001, respectively). The mean procedure time was lesser in unipedicular vertebroplasty (41.9 ± 3.90) than bipedicular vertebroplasty (54.5 ± 3.4). Conclusion Unipedicular vertebroplasty is as effective as bipedicular vertebroplasty, as there is insignificant difference in postprocedure VAS scores between the unipedicular and bipedicular vertebroplasty.

The main objectives of this study were to identify the teachers’ perceptions and challenges of using ICT tools in the mathematics classroom at the secondary level in Kathmandu. The major tool of the study was a closed-ended questionnaire consisting of 19 items. The quantitative descriptive survey design was used in this study. The researcher selected 158 teachers by using simple random method from 261 government teachers who teach compulsory mathematics at grade X of Kathmandu district in Nepal. The standardized questionnaire was administered to the sample teachers. The SPSS-25 version database was used to analyze and interpret the collected data. Teachers’ perception of using ICTs in the mathematics classroom was positive with insignificant difference in terms of gender. There were some challenges: lack of knowledge, confidence, enough experience, training, interest and access to ICT tools, lack of technical support, lack of genuine ICT Software and unstable and unreliable internet connection at the schools. Due to these challenges, teachers did not use ICT in the classroom. Therefore, teachers should learn more to improve their knowledge and skills in ICT. The government should focus on management strategies and policies to reduce the challenges faced by teachers in mathematics classrooms. By these policies, they can use the ICT tools in the classroom.

Introduction. Monitoring of students' health and physical fitness in general educational institutions is an integral part of the educational process, however, it takes much time on the part of teachers and school authorities responsible for collecting and storing information about health. The research relevance is substantiated by the need to preserve and strengthen students' health due to the dependence of the quality of education on the level of students' health and their performance. The research purpose was to test an electronic health passport in educational institutions for a comprehensive assessment of students' health and physical fitness indicators. Materials and methods. More than 600 schoolchildren of three age groups took part in the study: students aged 8-9 (298 students), 12-13 (244 schoolchildren), 15-16 (119 boys and girls) from general educational institutions in Lipetsk. Methods of assessing the morphofunctional state (measurement of body weight and length, blood pressure, heart rate monitoring, health coefficient calculation), the questionnaire method (assessment of school motivation, the study of self-esteem, diagnostics of learning motivation and emotional attitude to learning, the Ladder test) and methods of assessing physical fitness included in the All-Russian Physical Education and Sports Complex "Ready for Labor and Defense" were used. Research results. Significant differences (p<0.05) were determined in indicators of the health coefficient among schoolchildren from three general educational institutions in Lipetsk, and a tendency towards a decrease in the level of students' health from the lower grades to the higher ones was revealed. A decrease in indicators of school motivation and interest in the learning process was found in half of the students of primary school age (13-14 points out of 30 possible ones) and the majority of secondary school students (8-13 points out of 60 possible ones) and senior school students (7-12 points out of 60 possible ones). An insignificant difference (p>0.05) was found in the indicators of physical fitness of schoolchildren with different training profiles. The practice of introducing an automated electronic health passport system made it possible to systematize large amounts of information on various parameters characterizing the students' health and physical fitness in the shortest possible time and to optimize the teachers' work. Conclusion. The authors presented an experience of approbation of an electronic health passport, which made it possible to determine the level of physical, mental health and physical fitness of each student or group of students, formulate recommendations for students, parents and heads of educational institutions, as well as conduct a comparative characteristic of the studied indicators of schoolchildren from various educational institutions.

Background: There are insufficient data about the presence of E. albertii as a causative organism in urinary tract infection in pediatric patients. Objective: The present study aimed to detect E. albertii by polymerase chain reaction (PCR) for detection of uidA, mdh, and lysP genes among isolated E.coli from children with urinary tract infection. Methods: The present study was a cross-sectional retrograde study which was carried out on 100 isolates of phenotypically confirmed E.coli detected in urine samples of children suffering from urinary tract infection. The isolates were subjected to molecular identification by PCR for uidA, mdh, and lysP genes. Results: E. albertii was identified by PCR in 7% of the isolates and E.coli was identified in 93% of the isolates. Two mdh and lysP genes were detected for E. albertii and the uidA gene for E. coli. E. albertii isolates had marked resistance to gentamicin (71.4%), followed by resistance to ciprofloxacin (57.1%), meropenem and imipenem (42.9% each) and ESBL activity by double discs method was reported in 57.1% of the isolates. However, none of the isolates had shown resistance to nalidixic acid and only one isolate had resistance to norfloxacin. There was a statistically insignificant difference between resistance to the used antibiotics such as aztreonam (P=0.083), ampicillin/clavulanate (P=0.5), ciprofloxacin (P=0.69), gentamicin (P=0.3) and ceftazidime (P=1.00). Conclusion: The present study highlights the emergence of E. albertii as a pathogen associated with urinary tract infections in children. There is marked antibiotic resistance of this pathogen, especially toward extended spectrum beta-lactams antibiotics. The identification method depends mainly on genetic studies. Further longitudinal studies with large number of patients are required to verify the accurate prevalence of this bacterium.

PurposeThe aim of this study is to develop a knowledge scale for nutrients of tropical and traditional fruits for university students and conduct its validity and reliability. Another purpose of the study is to determine whether or not the students' knowledge mean scores about nutrients of tropical and traditional fruits vary based on their demographic information.Design/methodology/approachThe design of the study was the survey model. While the population consisted of 1,551 students studying in the faculty of health sciences, Gazi University, the sample consisted of 668 students who were determined based on criterion sampling.FindingsWhen examining in terms of gender of the students, it was determined that even though mean score of the knowledge scale for nutritional values of tropical and traditional fruits was slightly higher in female students (X¯ = 8.12) than male students (X¯ = 7.71), there was an insignificant difference between them (t(666) = 1.25, p > 0.05). A significant difference was determined between the students' knowledge mean scores of the knowledge scale for nutritional values of tropical and traditional fruits in terms of residence place (t(666) = 2.86, p < 0.5). While the nutritional value mean score of the students residing in Ankara was low (X¯ = 7.67), the nutritional value mean score of the students residing out of Ankara was high (X¯ = 8.58).Originality/valueWhen the scale developed in this study is analysed according to demographic information, it can be asserted that the students had knowledge about the nutrients of tropical and traditional fruits. Although tropical fruits are expensive, they still prefer these fruits. It can be stated that the students had knowledge about the diversity, nutritional compounds and antioxidant content of tropical and traditional fruits.

Aim: To analyze prevalence of cervical spondylitis among dentists practicing in Lahore. Methods: A cross sectional survey of 6 months was conducted on 110 dentists practicing in dental clinics of Lahore were examined using neck disability index performa. SPSS Version 24 used for entering/analyzing the data. Results: In 110 individuals, 22% dentists including males (n=19%) and females (n=24.2%) were suffering from cervical spondylitis. According to neck disability index 34.5% had no disability, 47.2% had mild, 10.9% had moderate, 5.4% had severe disability and only 1.9% had complete disability. The major number (30%) was among 41-50years, and also statistically significant difference was observed (p-value = 0.02). Similarly maximum number of cervical spondylitis was found among females, 15(24.2%) but statistically insignificant difference was observed with respect to gender (p-value = 0.493). Longer practicing experience had also significant impact on the occurrence of spondylitis (p-value <0.001). Conclusion: Dentists are likely to have neck pain prevalent in them and very few had cervical spondylitis (22%) but the damage could be reduced if postural changes and regular exercises could be adapted. Keywords: Cervical Spondylitis, Neck Disability Index, Postural Changes

This paper addresses the fusion estimation problem in tessarine systems with multi-sensor observations affected by mixed uncertainties when under Tk-properness conditions. Observations from each sensor can be updated, delayed, or contain only noise, and a correlation is assumed between the state and the observation noises. Recursive algorithms for the optimal local linear filter at each sensor as well as both centralized and distributed linear fusion estimators are derived using an innovation approach. The Tk-properness assumption implies a reduction in the dimension of the augmented system, which yields computational savings in the previously mentioned algorithms compared to their counterparts, which are derived from real or widely linear processing. A numerical simulation example illustrates the obtained theoretical results and allows us to visualize, among other aspects, the insignificant difference in the accuracy of both fusion filters, which means that the distributed filter, although suboptimal, is preferable in practice as it implies a lower computational cost.

TheLaser Assisted New Attachment Procedure (LANAP) protocol is a laser based periodontal regenerative procedure and was patterned, conceptually, after the Excisional New Attachment Procedure (ENAP) to separate the diseased epithelium from the underlying connective tissue and to selectively vaporize and disrupt inflamed and necrotic tissue from connective tissue.: The present study was designed to compare and evaluate the clinical efficacy of LANAP versus ENAP in the treatment of chronic periodontitis.: Twenty periodontal pocket sites of ≥5mm in systemically healthy patients were selected and randomly allocated to either (ENAP) Excisional New Attachment Procedure (Group I) or (LANAP) Laser Assisted New Attachment Procedure (Group II). Patients were evaluated for Plaque Index, Gingival Index, Gingival Bleeding Index, Probing Depth, Loss of attachment, recession and VAS scores. Patients were recalled for follow up at 1 week, 1 month and 3 months at which clinical parameters were recorded.: The results of the present study revealed statistically insignificant difference in both groups however clinically significant reduction in probing depth was seen with ENAP as compared to LANAP but laser procedure had less VAS scores as compared to ENAP.Although probing depth reduction was more for ENAP, patient discomfort with less bleeding was observed with LANAP.

AbstractIn this study, to increase the content of quercetin in the isolates obtained from the white and red onion scales, in accordance with the zero waste philosophy, using water as an environmentally and healthy friendly extractant, a mathematical model was constructed, based on the Central Composite Design. The suitability of the model for the accurate and quick study of complex relationships was demonstrated by obtaining a statistically insignificant difference in the yield predicted by the model and that determined experimentally under optimal extraction conditions, i.e., 44.14 mg/g (33.57 mg/g) and 45.54 mg/g (33.31 mg/g) for white (red) onion scales, respectively. To present the obtained isolates applicability, their biological activity was assessed in terms of antioxidant activity and antifungal activity against various fungi, showing properties that are sufficient to encourage the use of this material, previously treated as worthless waste, for the production of various functional ingredients, including functional food additives. Moreover, they can be also used to produce safe and effective protectants meeting the GRAS criteria.
