Effect of LED-mediatedphotobiomodulation therapy on orthodontic tooth movement and root resorption in rats

TANCAN UYSAL

Makale | 2013 | Springer

The aim of this experimental study was to evaluate the effects of light-emitting diode-mediated-photobiomodulation therapy (LPT), on the rate of orthodontic tooth movement (TM) and orthodontically induced root resorption, in rats. Twentymale 12-week-oldWistar rats were separated into two groups (control and LPT) and 50 cN of force was applied between maxillary left molar and incisor with a coil spring. In the treatment group, LPT was applied with an energy density of 20 mW/cm2 over a period of 10 consecutive days directly over the movement of the first molar teeth area. The distance between the teeth was measured with a di . . .gital caliper on days 0 (T0), 10 (T1), and 21 (T2) on dental cast models. The surface area of root resorption lacunae was measured histomorphometrically using digital photomicrographs. Mann–Whitney U and Wilcoxon tests were used for statistical evaluation at p Daha fazlası Daha az

Measurements from conventional, digital and CT-derived cephalograms: a comparative study

ASLI BAYSAL

Makale | 2012 | Australian Society of Orthodontists

Objective: The purpose of this retrospective radiographic study was to determine the reliability and reproducibility of skeletal and dental measurements of lateral cephalograms created from a computerised tomography (CT) scan compared with conventional and digital lateral cephalograms. Methods: CT and conventional lateral cephalograms of the same patients were obtained from university archives. The lateral cephalometric radiographs of 30 patients were manually traced. The radiographs were subsequently scanned and traced using Dolphin Imaging software version 11 (Dolphin Imaging, Chatsworth, CA, USA). The CT-created lateral ceph . . .alograms were also traced using the same software. Sixteen (10 angular and 6 linear) measurements were performed. Cephalometric measurements obtained from conventional, digital and CT-created cephalograms were statistically compared using repeated measures analysis of variance (ANOVA). Statistical significance was set at the p < 0.05 level of confidence. Results: The intra-rater reliability test for each method showed high values (r > 0.90) except for mandibular length which had a correlation of 0.82 for the CT-created cephalogram. Five measurements (N-A-Pog, N-S, ANS-PNS, Co-ANS and Co-Gn) were found to be significantly different between the CT-created and conventional cephalograms and three measurements (SNB, ANB, and /1-MP) were found to be significantly different between the CT-created and digital cephalograms. Conclusions: There are statistically-significant differences in measurements produced using a traditional manual analysis, a direct digital analysis or a 3D CT-derived cephalometric analysis of orthodontic patients. These differences are, on average, small but because of individual variation, may be of considerable clinical significance in some patients Daha fazlası Daha az

Treatments of horizontal root fractures: four case reports

EBRU KÜÇÜKYILMAZ

Makale | 2013 | Wolters Kluwer Health

Horizontal root fractures are rare in comparison to other types of injuries and the reported prevalence in the literature is between 0.5% and 7%. The treatment and prognosis of root fractures depend on many variables, the most important being the length of time between trauma and treatment, degree of dislocation and mobility, site of fracture, fixation period, stage of root development, age of patient, and quality of treatment. The ideal healing type is hard tissue healing. The aim of these case reports is to present four different patients who had horizontal root fractures of immature permanent teeth treated by repositi . . .oning and fixation with good healing. Patients were referred to our clinic with a complaint of mobility and tenderness in their upper central incisors as a result of an orofacial injury. As a result of radiographical examination, horizontal fractures were diagnosed on the roots. Teeth were repositioned and rigid fixation was applied. Splints were retained for about 12 weeks. After splints were removed, patients were scheduled for follow‑up visits at 3 month intervals. After long‑term clinical and radiographical follow‑up, all teeth presented positive response to electrical pulp tests, suggesting a repair of root fractures. These immature teeth showed radiographic evidence of continued root development and normal color and mobility, and no pain was observed in horizontal and vertical percussion tests. Patients reported no discomfort with their teeth. Using splints without any further treatment was found to be successful in the presence of suitable conditions for the treatment of horizontal root fractures Daha fazlası Daha az

Dentoskeletal effects of Twin Block and Herbst appliances in patients with Class II division 1 mandibular retrognathy

ASLI BAYSAL

Makale | 2014 | European Orthodontic Society

OBJECTIVE: The aim of this study is to evaluate dentoskeletal effects of Herbst and Twin Block (TB) appliance therapies in Skeletal Class II malocclusion. SUBJECTS AND METHODS: Herbst group consisted of 11 girls and 9 boys (mean age = 12.74±1.43 years), TB group comprised of 10 girls and 10 boys (mean age = 13.0±1.32 years), and control group included 9 girls and 11 boys (mean age = 12.17±1.47 years). Mean treatment/observation times were 15.81±5.96 months for Herbst, 16.20±7.54 months for TB, and 15.58±3.13 months for control group. Pre-treatment (T0) and post-treatment (T1) lateral cephalograms were traced using a modified Panc . . .herz’s cephalometric analysis. Inter-group differences were evaluated with one-way analysis of variance, and intra-group differences were assessed with paired samples t-test at the P < 0.05 level. RESULTS: In control group, all sagittal and vertical skeletal measurements increased as a result of continuing growth. However, skeletal discrepancy and overjet remained unchanged. After functional appliance therapy, greater increases were recorded in TB group for all mandibular skeletal measurements compared with those in control group. Upper dental arch distalization and lower incisor protrusion were significant in Herbst group, compared with control. All face height measurements increased after functional appliance therapy. IMPLICATIONS AND CONCLUSIONS: In TB group, the treatment effects were mainly due to mandibular skeletal changes. Both skeletal and dental changes contribute to Class II correction with Herbst appliance therapy. Herbst appliance may be especially useful in Skeletal Class II patients with maxillary dentoalveolar protrusion and mandibular dentoalveolar retrusion, whereas TB appliance may be preferred for skeletal mandibular retrognathy patients Daha fazlası Daha az

Objective: The workload and working hours of healthcare professionals have increased due to the COVID-19 pandemic. The aim of this study was to evaluate how COVID-19 outbreak restrictions affect dietary habits among healthcare professionals. Material and Method: The study population was 239 adults aged between 18-65 years. An online survey including questions about demographic variables, health information, lifestyle behaviors, and dietary habits were sent via an online platform. Self-reported weight, and height before and during the pandemic were also collected. Results: The percentage of those who skip the main meals during the lo . . .ckdown (48.1%) has increased compared to before the lockdown (43.9%). The most skipped main meal and snack were breakfast and mid-morning, respectively. Among the study population, 48.1% reported that they increased their vegetable-fruit consumption, 38.1% reported increased water intake and 45.6% reported consuming more home-cooked food. The most preferred snacks were fruits-vegetables (62.3%), and nuts (55.6%). Approximately half of the participants (46.0%) reported an increased appetite and 50.6% of the participants stated an increase in body weight during COVID-19. The weight gain of the 51-64 age group (3.73±4.13 kg) was statistically significantly higher than the 18-50 age group (0.43±4.51 kg) (p=0.014). The rate of those who reported doing at least 150 minutes of exercise per week before COVID-19 (43.9%) decreased during the pandemic (30.5%). Conclusion: Body weight, appetite, some dietary habits, and physical activities were generally adversely affected among healthcare workers during the pandemic. Older groups are most prone to weight gain during the lockdown Daha fazlası Daha az

Makale | 2021 | İzmir Katip Çelebi Üniversitesi Sağlık Bilimleri Fakültesi Dergisi6 ( 3 ) , pp.91 - 99

ABSTRACT Objective: Dermatological diseases are public health problems. Several factors including subjective diagnosis, lack of enough dermatologists, inability to go to a dermatologist due to old age, psychological problems or pandemic like coronavirus enforce to use automated techniques in dermatology. In the literature, there are many techniques on automated lesion classification to provide accurate, objective, reliable and reproducible results for the diagnosis of several dermatological diseases. However, although the techniques are promising, they become useless without a user interface for many patients or users who don’t hav . . .e any prior knowledge on how to choose or set appropriate parameters and how to run source codes. Therefore, the objective of this work is to develop an application with an efficient user interface for patients and dermatologists. Material and Method: The application has been developed with Matlab (R2019) using digital photographs provided from public databases. Results: An application with an efficient and friendly user interface has been designed and implemented for patients with dermatological diseases. Conclusion: The application can present results of (i) lesion segmentation, (ii) image classification, and (iii) analysis according to time periods. It provides to view data easily and parametrization of the network. It can also be useful for dermatologists to analyze lesions or make decisions about diseases. Also, the application can be used for educational purpose since it provides information and tests on dermatological diseases. Therefore, it can be useful for both patients and researchers working in this area. ÖZ Amaç: Dermatolojik hastalıklar halk sağlığı problemleridir. Teşhisin öznel olması, yeterli dermatolog bulunmaması, yaşlılık, psikolojik sorunlar veya koronavirüs salgını gibi nedenlerle dermatoloğa gidememek gibi çeşitli faktörler dermatolojide otomatik tekniklerin kullanılmasını zorunlu hale getirmiştir. Literatürde, çeşitli dermatolojik hastalıkların teşhisinde doğru, objektif, güvenilir ve tekrarlanabilir sonuçlar sağlamak için otomatik lezyon sınıflandırması üzerine birçok teknik vardır. Fakat bu teknikler, ümit verici olmasına rağmen, uygun parametrelerin nasıl seçileceği veya nasıl ayarlanacağı ve kaynak kodlarının nasıl çalıştırılacağı konusunda önceden bilgisi olmayan birçok hasta veya kullanıcı için, bir ara yüz olmadan faydasız hale gelmektedirler. Bu nedenle, bu çalışmanın amacı, hastalar ve dermatologlar için etkili bir kullanıcı ara yüzüne sahip bir uygulama geliştirmektir. Gereç ve Yöntem: Uygulama genel veri tabanlarından sağlanan dijital fotoğraflar kullanılarak Matlab (R2019) ile geliştirilmiştir. Bulgular: Dermatolojik hastalıkları olan hastalar için etkili ve kullanıcı dostu ara yüze sahip bir uygulama tasarlanmış ve geliştirilmiştir. Sonuç: Uygulama, (i) lezyon bölütleme, (ii) görüntü sınıflandırması ve (iii) zaman periyotlarına göre analiz sonuçlarını sunmaktadır. Verilerin kolayca görüntülenmesini ve ağın parametrelendirilmesini sağlamaktadır. Dermatologlar tarafından lezyon analizinde veya karar verme aşamasında da kullanılabilir. Ayrıca uygulama, dermatolojik hastalıklar hakkında bilgi ve testler sağladığı için eğitim amaçlı da kullanılabilmektedir. Dolayısıyla bu hem hastalar hem de bu alanda çalışan araştırmacılar için faydalı olacaktır Daha fazlası Daha az

Makale | 2013 | The Korean Association of Orthodontists

Objective: To evaluate lower incisor position and bony support between patients with Class II average- and high-angle malocclusions and compare with the patients presenting Class I malocclusions. Methods: CBCT records of 79 patients were divided into 2 groups according to sagittal jaw relationships: Class I and II. Each group was further divided into average- and high-angle subgroups. Six angular and 6 linear measurements were performed. Independent samples t-test, Kruskal–Wallis, and Dunn post-hoc tests were performed for statistical comparisons. Results: Labial alveolar bone thickness was significantly higher in Cl . . .ass I group compared to Class II group (p = 0.003). Lingual alveolar bone angle (p = 0.004), lower incisor protrusion (p = 0.007) and proclination (p = 0.046) were greatest in Class II average-angle patients. Spongious bone was thinner (p = 0.016) and root apex was closer to the labial cortex in high-angle subgroups when compared to the Class II average-angle subgroup (p = 0.004). Conclusions: Mandibular anterior bony support and lower incisor position were different between average- and high-angle Class II patients. Clinicians should be aware that the range of lower incisor movement in high-angle Class II patients is limited compared to average- angle Class II patients Daha fazlası Daha az

Objective: The aim of this study was to evaluate the predictive effect of the e-Health literacy level of individuals on attitudes towards protection from COVID-19 and the level of fear during the COVID-19 pandemic. Material and Method: The population of this cross-sectional study included individuals who could be reached through social media channels (Facebook, Instagram, WhatsApp) and e-mail between July and October 2020, and the sample of the study consisted of 522 literate individuals who had internet access and agreed to participate in the study. Data were collected using the personal identification form, the e-Health Litera . . .cy Scale (eHEALS), and the Fear of COVID-19 Scale (FCV-19S). Statistical analyses were performed using Mann-Whitney U test, Kruskal-Wallis test, Posthoc analysis, Binary Logistic Regression analysis, and Simple Regression Analysis. Results: 53.4% of the participants are women, 89.5% are university graduates, 60.3% are working in a job. The e-health literacy scores of those who follow the current information to prevent COVID-19 infection, wash their hands, use disinfectants, and stay 2 meters away from people compared to others, and those who act in accordance with the recommendations of the experts, were statistically significantly higher than those who behaved in line with the bans. Presence of chronic disease among family members, young age and high level of health literacy are predictive factors of COVID-19 fear. Conclusion: The results of this study have shown that the level of fear of COVID-19 increases as the e-Health literacy level increases. As the e-Health literacy score of individuals increases, the rate of apply the preventive measures against COVID-19 also increases Daha fazlası Daha az

Makale | 2023 | İzmir Katip Çelebi Üniversitesi Sağlık Bilimleri Fakültesi Dergisi8 ( 2 ) , pp.343 - 353

Objective: The aim of this study was to evaluate the differences in psychological symptoms between disabled and non-disabled individuals. Material and Method: This paper conducts a multi-facet analysis (depression, anxiety, negative self, hostility and somatization) on disabled people for the first time. This study included 24493 people (non-disabled=23391, disabled=1102) from 9 demographic regions in Turkey and participants in the study were 18 years or older. Socio-demographic information form and Brief Symptom Inventory (BSI) were used as data collection tools. The participants' scores from the BSI were evaluated according to t . . .heir disability status for each of the subdimensions of depression, anxiety, negative self, hostility and somatization. Results: When the mean BSI scores of the participants were compared, it was seen that the lowest mean scores in all sub-dimensions belong to non-disabled individuals. When the groups of people with disabilities were compared according to psychological symptoms, there were no differences for the 4 symptoms, whereas the scores of individuals with chronic disease were significantly higher in the somatization sub-dimension than the others. It was observed that hearing impaired individuals had the lowest mean score in anxiety, somatization and hostility sub-dimensions among the groups of disabled individuals. Conclusion: Increasing awareness of disabled people in society and supporting them with psychotherapy methods that will improve the resistance mechanisms and increase adaptation to disability will contribute to social welfare.
