Kinetic Analysis of the Adsorption of Malachite Green onto Graphene Oxide Sheets Integrated with Gold Nanoparticles
Authors: Sabo Ibrahim Alhaji , Yahuza Salihu , Dan-Iya Bilal Ibrahim , Abubakar Abdussamad
Published: January 2022

Malachite green is extensively used in the textile dye industry and in agriculture as fish pests’ pesticide. Biosorption is a type of sorption technique that uses a biological sorbent. As of now, biosorption is viewed as a simple and cost-effective process that might be used as an alternative to traditional pollution treatment methods. Bioremediation is one of the branches of bioremediation that is used to minimise pollution in the context of incorrect textile waste disposal. The sorption isotherm of Malachite Green onto graphene oxide were analyzed using three models—pseudo-1st, pseudo-2nd and Elovich, and fitted using non-linear regression. The Elovich model was the poorest in fitting the curve based on visual observation and the best was pseudo-2nd order based on statistical analysis such as root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), corrected AICc (Akaike Information Criterion), Bayesian Information Criterion (BIC) and Hannan–Quinn information criterion (HQC). Nonlinear regression analysis using the pseudo-2nd order model gave values of equilibrium sorption capacity qe of 6.164 mg/g (95% confidence interval from 5.918 to 6.410) and a value of the pseudo-2nd-order rate constant, k2 of 0.034 (95% confidence interval from 0.024 to 0.045). Further analysis is needed to provide proof for the chemisorption mechanism usually tied to this kinetic.

Closing the Achievement Gap in the Classroom Through Culturally Relevant Pedagogy
Authors: Hernandez Awilda
Published: January 2022

It has been shown that Culturally Relevant Pedagogy is beneficial in schools with a wide range of populations because of its emphasis on academic achievement for all students, cultural competency, and social justice issues. This study focused on teachers’ perceptions about how to use a Culturally Relevant Pedagogy model in the classroom. Interviews with 20 in-service teachers across eight states revealed the following themes: (a) teachers’ ideas about Culturally Relevant Pedagogy and the classroom environment, and (b) school and district support on Culturally Relevant Pedagogy and social community, resources, and teachers’ training to understand Culturally Relevant Pedagogy. This paper explores themes to reveal how in-service teachers perceived their preparedness to teach using CRP strategies in the classroom. In order to close the achievement gap, a paradigm change is required. It is necessary to employ CRP strategies to create this change and integrate students’ everyday life with classroom learning objectives so that achievement disparity in classrooms may be reduced. English Language Learners (ELLs), students with low socio-economic status, and racial/ethnic minorities were the focus of this study.
Who Is Who in the Teaching of Sex Education? A Lesson Learned from the 'Safuu' Oromo Tradition of East Africa
Authors: Tucho Admasu Etefa
Published: January 2022

The 2020 National Center for Education Statistics (NCES) data show that there are a total of 130,930 k-12 public schools in the United States of America (U.S.A), serving approximately 48.1 million students. The demographic breakdown of the student population includes 22 million (45.7%) Whites; 13. Million (32 %) Hispanic; 17.2 million (14%) African American; 2.6 million (5.4%) Asian, 2.2 million (4.6%) students two or more races; and 0.4 million (0.8%) American Indian/ Alaska Native students. Adding sex education to the public school curriculum was primarily to make elementary and secondary school students aware of sexually transmitted diseases and teenage pregnancy. Although comprehensive sexuality education has been operational in all 50 states for decades, the program's quality and comprehensiveness vary considerably from state to state due to a series of obstacles. The author of this article proposes an alternative or at least supplemental approach to the current comprehensive sex education.

Published: January 2022

Aim: The purpose of this in vitro study is to compare the cyclic fatigue resistance of Reciproc Nickel-Titanium (Ni-Ti) rotary files while operating root canals using in three different reciprocal angles.

Methodology: Forty-five pieces of Reciproc R25 canal files were tested using artificial canals with a 60° angle of curvature, 5 mm curvature radius, and 1.5 mm diameter carved into a stainless steel block. The Ni-Ti files were checked with a stereomicroscope and then randomly separated into 3 groups. Group 1 consisted of reciprocal angles CCW 150°–CW 30°, Group 2 consisted of CCW 180°–CW 60°, and Group 3 consisted of CCW 210°–CW 90°. The duration of the cyclic fatigue being measured, elapsed time until a file fractured was determined with a chronometer. The lengths of the fractured pieces were measured with a digital caliper. After the cyclic fatigue test, two samples from each group were examined with a Scanning Electron Microscope (SEM) to determine the signs of cyclic fatigue.

Results: One-way analysis of variance (ANOVA) was applied to the normally distributed groups (p<0,05). Since there was a significant statistical difference of file’s cyclic fatigue resistance (p=0,001) between the groups, Tukey’s honestly significant difference (HSD) post-hoc pairwise comparison test were used for determine to between which groups. While there were statistically significant differences between Group 1 and Group 2 (p=0,001), and between Group 1 and Group 3 (p=0,001), there was no significant difference between Group 2 and Group 3 (p=0,376). Group 1 displayed the highest resistance to cyclic fatigue. There were no statistically significant differences between the lengths of the fractured files within the three groups according to the one-way analysis of variance (p=0,847).

Conclusion: In our study, it was observed that the reciprocal angles of CCW 150°–CW 30°, which were also suggested by the file manufacturer firms, had the highest fracture resistance against cyclic fatigue.

The effect of optical brightening toothpaste on the color stability of esthetic restorative materials
Authors: Kahvecioğlu Firdevs , Çoban Elçim , Ülker Hayriye Esra
Published: January 2022

Aim: The aim of this study is to evaluate the effects of whitening toothpaste applications on the color stability of different tooth-colored restorative materials (Fuji IX, GC Fuji II LC, Equia Forte, and Kerr Point 4) 

Methodology: Standardized fourty disc-shaped specimens were prepared from esthetic restorative materials and polished. The baseline color values of each specimen were then measured using a spectrophotometer, according to the Commission Internationale de l'Eclairage L*, a*, and b* (CIELAB) color scale. Ten specimens from each group were then immersed in two different beverages (cherry juice and coke) for seven days. After immersion, the color value of each specimen was re-measured. Each sample was brushed with whitening toothpaste for 30 seconds using an electric toothbrush. The samples were kept in distilled water at room temperature and brushing continued twice a day for seven days. The color change value, Delta E (ΔE), was calculated. Data were analyzed by two-way ANOVA and post hoc Tukey's test.

Results: When the results were evaluated, after the colored samples had been brushed with whitening toothpaste, a difference was found between the Delta E values according to the materials used (p<0.001), but no difference was found in relation to the beverages (p>0.001). When the values of the color changes were evaluated after the first brushing with whitening toothpaste and before the specimens were colored with drinks, a difference was observed in the Fuji II cola, Fuji II cherry, and Equia Forte cola groups (p<0.05). When the values of the color changes were evaluated for specimens in which brushing had been done twice a day for seven days with whitening toothpaste and before they were colored with drinks, a significant difference was observed in the Fuji II cherry and Equia Forte cola groups (p<0.05).

Conclusion: Using Signal White Now whitening toothpaste for 2 min 2 times a day for seven days caused significant changes in the color of the restorative materials. The color change is dependent upon the type of restorative material that is used.

Readability and content assessment of patient information texts on oral cancers found on Turkish websites
Authors: Kaya Doğan Ilgaz
Published: January 2022

Aim: Oral cancer is one of the health problems that results in high mortality in the community. It is known that, when diagnosed in the later stages (3 or 4), the disease is difficult to treat. Patient education on heredity and early diagnoses are critical for the successful treatment of oral cancer. This study aimed to evaluate Turkish texts about oral cancers found online in terms of their readability and content.

Methodology: The first 100 websites returned from a Google search using the keywords "Ağız kanseri" (“oral cancer,” in Turkish) were examined. The patient information texts obtained were evaluated according to the Ateşman Readability Index. Their contents were also evaluated in terms of whether or not they provided sufficient information about the disease.

Results: It was understood that the texts examined in the study were of medium difficulty according to the Ateşman Readability Index (mean 61.73± 11.81). The content of the information on the websites examined in the study was deemed sufficient and useful. Most of the websites examined were those of private clinics and hospitals.

Conclusion: The results of the study indicated that the patient information texts found on Turkish websites were of medium reading difficulty. Although they are sufficient in terms of content, if they are not understood by the patients, their intended effects on readers will not be seen.

The effects of type-I collagen membrane, hydroxyapatite, and platelet-rich plasma on bone regeneration: An experimental study
Authors: Çetin Genç Çiğdem , Gülsün Belgin
Published: January 2022

Aim: Various methods have been developed to support bone reconstruction, including the use of autogenous, allogenic, and synthetic bone graft substitutes, membranes, and concentrated supplements. This study aims to compare the effects of collagen membrane, hydroxyapatite, and platelet-rich plasma on the bone regeneration process in a rat model.

Methodology: The experiment was conducted with 60 female Wistar albino rats. Subjects were divided randomly into three groups (n: 20). In the first group, the right femurs' defects were left empty (group I), and type-I collagen membrane was applied to the left femurs (group II). Type-I collagen membrane + hydroxyapatite (group III) was applied to the second group, and type-I collagen membrane + hydroxyapatite + platelet-rich plasma (PRP) (group IV) was applied to the third group. Thus, a total of 80 femurs were included in the study, and defects were evaluated histologically on the 10th, 21st, 45th, and 90th days (n: 5).

Results: Groups II and III had better osteogenesis scores than group I, whereas group IV had better results than all other groups. 

Conclusion: In the PRP group, the osteogenesis scores were significantly better than the other groups. However, the healing was almost excellent in all three study groups (groups II, III, and IV) at the end of the experiment.

Clinical and radiological of the effects of two different implant surfaces on marginal tissues
Authors: Bingül Muhammet Bahattin , Gülsün Belgin
Published: January 2022

Aim: In this study, our aim is to compare the effects of dental implants with nano laser excimer technology surface (NLE) and dental implant surfaces (MTX) with micro-roughened surface on marginal tissues with clinical and radiological data.

Methodology: A total of 117 dental implants were followed clinically and radiologically. Clinically; Plaque index (silness-leöe), bleeding index in boring, pocket depth were evaluated and recorded 1 week after the insertion of the healing cap, 3 months, 6 months and 12 months after the end of the prosthesis. In the same periods, periapical x-rays were taken with the Rinn Holder method and the amount of marginal bone loss was measured. The data were analyzed with IBM SPSS Statistics Version 22 package program.

Results: There was no loss in the implants included in the study. There was no statistically significant difference between the groups in terms of plaque index, bleeding index values (p>0,05). However, the pocket depth of the dental implant group with nano laser excimer technology surface is significantly lower than the micro-roughened surface group. There are statistically significant differences between the groups in terms of radiological marginal bone loss at 0, 3, 6, and 12 months (p<0,05). Radiological marginal bone loss values ​​of the micro-roughened surface group at 0, 3, 6, and 12 months were significantly lower compared to the same periods of the nano laser excimer technology group.

Conclusion: It has been determined that the surface properties of dental implants can be effective on marginal tissues. In addition, we believe that routine checks by dentists who perform dental implant applications will increase the success of dental implants.

Effects of removable dental prostheses on mandibular bone density in postmenopausal osteoporotic patients
Authors: Ateş Sinan , Gülsün Belgin
Published: January 2022

Aim: To investigate the effects of removable dental prostheses on mandibular bone density in postmenopausal osteoporotic patients.

Methodology: The prospective study included 30 female patients aged 45–70 years who had been previously diagnosed with postmenopausal osteoporosis. The patients had no diseases affecting bone metabolism. The patients were divided into two groups: (i) patients who were using removable dental prostheses (n=15) and (ii) patients who were not using removable dental prostheses (n=15) (the control group). A whole-body dual energy x-ray absorptiometry (DXA) scan was performed to calculate the mandibular bone densities of the patients.

Results: The use of removable mandibular prostheses did not cause a significant change in mandibular bone density.

Conclusion: The fact that removable mandibular prostheses did not cause a significant change in mandibular bone density could be because the patients started using the removable prostheses long after they lost their teeth.

An evaluation of the relationship between periocular anthropometric measurements and mandibular incisor crowding
Authors: Kızıltan Eliaçık Başak
Published: January 2022

Aim: To determine whether a relationship exists between the periocular anthropometric meas-urements (POAM), intercanine width, and Little’s irregularity index (measures the crowding of mandibular incisors) in the Turkish population.

Methodology: Ninety-four children (49 with mandibular crowding and 45 controls) aged between 12-18 years were included in this study. Inter-outer canthal distance (IOCD), in-ter-inner canthal distance (IICD), interpupillary distance (IPD), inter-canine width (ICW), and Littles’irregularity index (LII) of subjects were measured from two standardized digital pho-tographs using a public domain Java processing program (ImageJ software). Spearman correla-tion coefficient and multiple linear regression tests were used to investigate the relationship between POAM, and ICW, and LII.

Results: In the mandibular crowding group, the means of IICD, OICD, IPD, and ICW were 30.6 ± 1.7 mm, 82.4 ± 2.0 mm, 59.2 ± 1.6 mm, 23.3 ± 1.1 mm, respectively. In controls, the mean of the measurements was found to be 32.1 ± 1.5 mm, 84.4 ± 2.4 mm, 60.1 ± 1.9 mm, 24.6 ± 1.4 mm, respectively. There were statistically significant differences between groups among all variables (p <0.001). There was a negative correlation between POAM and ICW with LDI. Especially, high correlation was found in ICW and IICD variables (r = -. 732, p <.001 and r = -705, p <.001, respectively). As a result of multivariate regression analysis, IICD and ICW were found to be affected the crowding negatively and significantly (p = .003 and p = .026, respectively).

Conclusion: According to the results obtained from our study, it was concluded that IICD which remains stable after the age of 10 years and ICW can be used to predict irregularities in mandibular incisors in children in the Turkish population.

Authors: Özüdoğru Semanur , Tosun Gül
Published: January 2022

Aim: This retrospective study investigated the survival rate and clinical performance of space maintainers fitted in 50 patients aged from 6-11years in the Department of Pediatric Dentistry at Selcuk University between 2016 and 2019.

Methodology: Sixty-one subjects were included in the study. The clinical examination included performing the gingival index (GI) and the plaque index. The values of the indexes were determined and compared, and the failures of retainers were recorded and analyzed in terms of survival.

Results: Follow-up loss occurred in 18% of 61 space maintainers. A total of 10% of the evaluated 50 space maintainers had failed due to breakage. By using the Kaplan–Meier method, the estimated mean survival time for space maintainers was 13 months. Lingual arches had the lowest mean survival time of 12 months. Band and loops and removable partial dentures had a similar probability of survival. A significant decrease was observed in the time-dependent evaluation of the means of plaque and gingival indexes; however, no significant difference was found between space maintainer types.

Conclusion: The successful use of space maintainers for the premature loss of primary tooth space is achieved by regular follow-ups with the patient’s parents, patient cooperation, and proper space maintainers and choice of material.

Authors: Savaş Abdulhaluk , Büyükerkmen Emine Begüm , Tunçdemir Ali Rıza
Published: January 2022

Aim: The purpose of this study is to determine the levels of dental anxiety in patients who applied to the Necmettin Erbakan University Faculty of Dentistry during the COVID-19 outbreak and to evaluate the relationships of their anxiety levels to age, gender, education level, and the frequency of visits to dentists.

Methodology: There were 320 participants, including 163 females (50.9%) and 157 males (49.1%), aged from 18 to 65 years or older, who had applied to the Necmettin Erbakan University Faculty of Dentistry. The Corah Dental Anxiety Scale (CDAS) was used to determine the levels of dental anxiety (non-anxiety, little anxiety, anxiety, over anxiety, and excessive anxiety) and the anxiety groups (low or high). Descriptive statistics were presented in percentages. Data were analyzed using t-tests and one-way ANOVA and chi-square tests, at a significance level of p = 0.05.

Results: Among the participants, 38.1% were at the non-anxiety level, 44.1% had very little anxiety, 10.9% had anxiety, 5% had over anxiety, and 1.9% had excessive anxiety. With regard to the anxiety groups, 82.5% were in the low anxiety group, and 17.5% were in the high anxiety group. Age, education level, and frequency of visiting the dentist were not found to have any effects on dental anxiety (p > 0.05). However, the effect of gender with regard to dental anxiety was significant (p < 0.05), as females had higher dental anxiety levels than males.

Conclusion: While the effect of gender was found to be important in terms of dental anxiety, age, educational status, and the frequency of visiting the dentist did not have significant effects on dental anxiety. Females had higher dental anxiety scores and levels than males.

Authors: Uçan Yarkaç Fatma , Tekin Atay Ümmühan , Dinçer Nisa Nur , Öncü Elif
Published: January 2022

Aim: Coronavirus disease 2019 (COVID-19) can cause stress, anxiety, and fear, especially in healthcare workers as it has a high risk of transmission. The aim of this study was to investigate the levels of stress and anxiety during the COVID-19 pandemic among dentists working in our country.

Methodology: The study included 164 dentists. Sociodemographic data and the stress and anxiety levels of the individuals who participated in the study were recorded. The COVID-19 Stress Scale and the Perceived Stress Scale-10 were used for evaluation of the stress levels, and the Generalized Anxiety Disorder 7 was used to evaluate the anxiety levels. All data were considered statistically significant at p < 0.05.

Results: Among those who participated in the study, 112 were women and 52 were men, and 50% of them were 20 to 30 years of age. Based on the information these dentists provided, 63% did not have any expertise and 66% had worked in the normalization process. Their scores in the COVID-19 Stress Scale, the Generalized Anxiety Disorder Scale 7, and Perceived Stress Scale-10 were 64.4 ± 25.2, 5.46 ± 4.8, and 18.8 ± 5.9, respectively, and there was a positive correlation between all scales. When evaluating the stress levels according to gender, it was observed that those of the female dentists were higher than those of the male dentists (p < 0.05). There was no significant difference in the anxiety levels between the male and female dentists. While there were no significant differences between the dentists who worked during the pandemic process and those who did not work (p > 0.05), the COVID-19 stress levels were found to be lower in the normalization process (p < 0.05).

Conclusion: The COVID-19 pandemic has caused stress and anxiety in dentists and has affected female dentists more than male dentists. In addition, working during the pandemic process can benefit dentists by helping to reduce the stress caused by the pandemic.

Authors: Özdemir Eda , Bolgül Behiye
Published: January 2022

Aim: The aim of this study was to evaluate the surface hardness of dual-cure, bulk-fill composite resins at different depths and time intervals using nanoindentation.

Methodology: In the study, a comparison was conducted of the nanohardness values of Fill-Up, HyperFIL, and Cention N dual-cure, bulk-fill composite resins in the experimental group and Reveal HD, a light-cured, bulk-fill composite, in the control group. The dual-cure, bulk-fill composites used in the experimental group were divided into two subgroups. The first group was polymerized with an LED light source, and the second group was chemically polymerized in line with the manufacturer's instructions. The dual-cure composite resins were prepared in two different depths, 5 mm and 10 mm. In the control group, specimens with a depth of 5 mm were prepared, and their polymerization was provided by an LED light source. The nanohardness values of the lower and upper surfaces of the samples were measured using the Hysitron TI 950 Triboindenter 24 hrs and 7 days after polymerization.

Results: Following statistical evaluations, no statistically significant difference was found between the nanohardness values measured 24 hrs and 7 days after light or chemical polymerization of the dual-cured, bulk-fill composite resins. It was observed that light polymerization of HyperFIL and Fill-Up dual-cure, bulk-fill composite resins had no effect on nanohardness values. When Cention N dual-cure, bulk-fill composite resin was polymerized with a light source, higher values of nanohardness were obtained.

Conclusion: It was determined that the investigated dual-cure, bulk-fill composites reached their final hardness after 24 hrs. In all groups, it was observed that the highest nanohardness values belonged to Cention N for both polymerization methods.

Temporary adhesive bridge restoration of the upper anterior teeth lost due to trauma: Three case reports
Authors: Şahin Meryem , Totancı İsmet Rezani
Published: January 2022

Aim: Traumatic dental injuries at the anterior region of the maxilla occur frequently in children and adults. In this case report, we aimed to describe the temporary aesthetic restoration of the upper lateral incisor with a fiber-reinforced bridge by using the original tooth crown, which had avulsed after dental trauma.

Methodology: Case 1: A 14-year-old girl with an avulsion in tooth #11 due to trauma visited our clinic. During the examination, it was seen that the wound had healed, and there was no luxation in teeth #21 and #12. Since the patient could not undergo prosthetic procedures, for reasons including implants, and did not want a removable prosthesis, a single crown supported by acrylic tooth fibers was constructed.

Case 2: A 17-year-old male patient was referred to our clinic because of an avulsed left lateral incisor tooth, which was traumatized 15 days before visiting the clinic. His medical history revealed that his parents had found the tooth two hours after the trauma. However, the emergency clinic that he had previously visited did reimplant that tooth and repaired it with fiber-reinforced composite.

Case 3: In the examination of a 12-year-old male patient who applied to our clinic due to trauma, it was observed that tooth #11 had an avulsion and tooth #12 had a crown fracture. Root canal treatment was performed. A crown was made for the patient by supporting the fiber inside the canals of tooth #11 and tooth #21. It was revised aesthetically with the support of the crown of the other tooth.

Conclusion: Avulsion after anterior trauma affects patients’ appearance aesthetically; thus, patients want to be treated as soon as possible. Function, phonation, and aesthetics must be quickly provided for a loose anterior tooth. Fiber-reinforced adhesive bridge techniques may be considered as a temporary treatment for providing an aesthetically appealing appearance until the completion of permanent prosthetic treatment.

Correction of persistent crowding in the lower anterior region: A case report
Authors: Cime Akbaydogan Leyla , Baka Zeliha Muge , Ulusoy Mutluol Esra
Published: January 2022

Aim: This case report demonstrates the application of piezocision in correcting persistent crowding in the lower anterior region of dental arch.

Methodology: A female aged 14 years and 3 months presented to the Selcuk University Department of Orthodontics due to aesthetic complaints. Clinical and radiological examination revealed crowding in the upper and lower dental arches as well as skeletal and dental Class I malocclusion. First, bonding and arch wire were applied to the patient’s upper jaw. The patient then had check-up appointments at 4-week intervals. In the second session, bonding was applied to the lower jaw. As the leveling was completed in the upper jaw, thicker arch wires were used. However, 4 months after the bonding of the lower anterior region, leveling did not occur. Consequently, piezocision was applied to the lower anterior region. Then, two applications of 0.014'' and 0.016'' NiTi wire were carried out, respectively. After the completion of the leveling, intrusion was provided with the utility arch placed on the lower incisor brackets. Orthodontic treatment was concluded with the use of NiTi and steel angle wires.

Conclusion: Efficient leveling was achieved in the lower anterior region with piezocision applications.

Childhood trauma and perceived control in adulthood
Authors: Matras Agnieszka , Kozela Magdalena , Pająk Andrzej
Published: January 2022

Introduction: Prejudices might negatively influence the well-being of people they concern and often lead to discrimination. Hence, it’s important to search for effective ways to improve intergroup attitudes and implement them during education. One of the most effective known methods
is intergroup contact. However, as it’s not always possible to implement, it’s important to search for more accessible methods. The article proposes a new form of reducing prejudices, i.e. a letter of contact with fictitious outgroup members. In such interaction, people receive a letter and are asked for a reply. The method is based on two concepts of improving attitudes: imaginary contact and narrative about positive intergroup interaction. Its effectiveness in improving attitudes was experimentally tested and compared to a typical imaginary contact task.
Method: Participants were 179 high school students. They were divided into three experimental conditions: replying to a letter from an outgroup member; replying to a similar letter from an ingroup member; imagining interaction with an ingroup member. After the manipulation,
participants completed an intergroup attitudes questionnaire.
Results: What had an impact on intergroup attitudes was the perceived pleasure of the task, while the type of manipulation had no effects.
Conclusions: Results suggest that in manipulations based on imaginary contact or narration, responses are probably influenced not by imaging interaction with an outgroup member, but by the positive character of the task, which probably has an impact on attitudes by priming a good
mood. This calls into question the effectiveness of methods of imaginary contact and narrative about the contact. They probably temporarily affect mood but have no influence on prejudice.

Published: January 2022

Objectives: This study aims to evaluate the cost expenses and rehabilitation share of hand and/or wrist injuries and to contribute to the development of health and economic policies.

Patients and methods: A total of 59 patients (55 males, 4 females; mean age: 39.1±11.3 years; range, 20 to 64 years) who presented with hand and/or wrist injuries between January 2015 and December 2017 were retrospectively reviewed. Demographic data, hand injury information, and the Modified Hand Injury Severity Scores (MHISS) were retrieved from the patient file system. The cost analysis with direct and indirect costs was performed.

Results: According to the MHISS, 27.1% of patients had a minor injury, 23.7% had a moderate injury, 18.6% had a severe injury, and 30.5% had a major injury. The mean direct cost of the patients was $726.00±641.87 and the total cost of the indirect cost was $2,776.93±1,619.00. The mean day-off time was 125±68.62 days. Indirect costs accounted for 79% of the total cost. The mean cost of rehabilitation was $150.18±86.88. Rehabilitation costs accounted for 4% of the total cost. There was a positive correlation between the MHISS and direct, indirect and total cost, but not between the MHISS and rehabilitation cost.

Conclusion: The proportion of the share allocated to rehabilitation expenditures, which is the subunit of direct cost, is low and not related to the injury severity. The data obtained from the study contributed to the creation of evidence-based health and economic policies. We believe that these data also contribute to the planning of rehabilitation services according to the severity of injury which would improve the quality of life and return to work.

Objectives: This study aims to investigate the effects of adapted physical exercise on the level of muscular ability and attention process in patients with traumatic brain injury (TBI).

Patients and methods: Between September 2018 and November 2018, a total of 25 male patients with TBI (mean age: 41.1±9.7 years; range, 30 to 50 years) that occurred two years ago were included in this randomized-controlled study. The patients were divided into two groups as the experimental group (n=13) and the control group (n=12). The experimental group implemented a regular rehabilitation program and an additional program of adapted physical exercise. The control group implemented only a regular rehabilitation program (morning gymnastics and gymnastics for the brain). Motor and functional abilities were assessed by a Senior Fitness battery and Berg's balance scale. Attention process was assessed by a standardized d2 test.

Results: A significant improvement in physical abilities (strength, flexibility and balance) and attention process was observed in both groups (p<0.01). The improvement was greater in the experimental group (p<0.01).

Conclusion: Traumatic brain injury causes difficulties in the memory and executive functions of the body and impairs working ability. The short-term adapted physical exercise program can yield a positive change in working abilities of patients with TBI.

Published: January 2022

Objectives: The aim of this study was to compare the efficacy of home-based upper extremity circuit training exercises (CTEs) with supervised hospital program in male patients with traumatic complete paraplegia.

Patients and methods: Twenty men with paraplegia (mean age: 38±10.1 years; range, 30 to 43 years) between January 2007 and November 2007 were randomized into two groups. The first group had supervised hospital CTE program, whereas the second group had home-based CTE. The effects of the upper extremity CTE by using elastic bands 60 min per day, five days a week, for a total of eight weeks (70% maximal oxygen consumption [VO2max]) were examined. The Cybex was used for the isokinetic testing of the upper extremities. The VO2max and maximum heart rate (HR) were assessed using an arm ergometer. The Craig Handicap Report Technique Short Form (CHART-SF) was used for the evaluation of functional independence and mobility. Serum lipid profiles were measured.

Results: The mean injury duration was 7.9±2 years. The peak torque values of the upper extremities, VO2max, maximum HR, CHART-SF physical independence and mobility scores, and serum lipid profile were all improved in both groups (p<0.05). There were no significant differences in terms of the increase in the muscle strength and serum lipid levels between the groups (p>0.05). The improvement in the VO2max, physical independence, and mobility scores were greater in the supervised exercise group.

Conclusion: Upper extremity strength, cardiovascular endurance, and lipid profile were improved after supervised and home-based CTE in the men with paraplegia. Home-based exercise programs may be good alternatives to the hospital rehabilitation for this patient population.

Objectives: This study aims to investigate the prevalence, etiology, and risk factors of cervicogenic dizziness in patients with neck pain.

Patients and methods: Between June 2016 and April 2018, a total of 2,361 patients (526 males, 1,835 females; mean age: 45.0±13.3 years; range, 18 to 75 years) who presented with the complaint of neck pain lasting for at least one month were included in this prospective, cross-sectional study. Data including concomitant dizziness, severity, and quality of life (QoL) impact of vertigo (via Numeric Dizziness Scale [NDS]), QoL (via Dizziness Handicap Inventory [DHI]), mobility (via Timed Up-and-Go [TUG] test), balance performance [via Berg Balance Scale [BBS]), and emotional status (via Hospital Anxiety- Depression Scale [HADS]) were recorded.

Results: Dizziness was evident in 40.1% of the patients. Myofascial pain syndrome (MPS) was the most common etiology for neck pain (58.5%) and accompanied with cervicogenic dizziness in 59.7% of the patients. Female versus male sex (odds ratio [OR]: 1.641, 95% CI: 1.241 to 2.171, p=0.001), housewifery versus other occupations (OR: 1.285, 95% CI: 1.006 to 1.642, p=0.045), and lower versus higher education (OR: 1.649-2.564, p<0.001) significantly predicted the increased risk of dizziness in neck pain patients. Patient with dizziness due to MPS had lower dizziness severity scores (p=0.034) and milder impact of dizziness on QoL (p=0.005), lower DHI scores (p=0.004), shorter time to complete the TUG test (p=0.001) and higher BBS scores (p=0.001).

Conclusion: Our findings suggest a significant impact of biopsychosocial factors on the likelihood and severity of dizziness and association of dizziness due to MPS with better clinical status.
