Öğe Comparison of the Frequencies of Dentistry Examinations Among Chronic Patients at High-Risk for COVID-19 Before and During the Pandemic: A Cross-Sectional Study(2022) Dedeoğlu, Numan; Altun, Oguzhan; Duman, Şuayip Burak; Eser, Gözde; Özen, Duygu ÇelikObjective: This study aims to evaluate the frequency of dental examinations among chronic patients, a high-risk group for the coronavirus disease-2019 (COVID-19), before and during the pandemic. Material and Methods: A total of 27,757 patient records were evalu ated. Patients with diabetes mellitus, hypertension, cardiovascular (DHC) diseases, chronic respiratory diseases and chronic kidney failure and transplant patients, cancer patients, pregnant women and patients aged above 65 years were accepted as having risky chronic health conditions for COVID-19. However, those with at least 2 or 3 of DHC diseases were considered as a separate group. The frequencies of patient groups’ dental examinations were statistically compared for the period before and during the pandemic. In addition, the frequencies of patient groups dental examinations were also compared by gender for the general pop ulation and patients over 65 years of age. Results: The frequency of den tal examinations statistically significant decreased among both male and female patients, aged over 65 years and general population during the pandemic compared to before period in DHC patients (p<0.05). There was no statistically significant decrease in the frequency of dental ex aminations during the pandemic compared to the previous period in any disease group (except DHC) in the general male population and males over 65 years of age (p?0.05). Conclusion: Risky patients in DHC group were more careful in dental examinations during the pandemic. Men with risky chronic conditions may not have been feel anxious about COVID 19 when they referred to the dentist during the pandemic.Öğe Dental age assessment The applicability of Demirjian method in southwestern of eastern Anatolia region Turkish children(Cumhuriyet Dental Journal, 2012) Karataş, Orhan H.; Öztürk, Fırat; Dedeoğlu, Numan; Çolak, Cemil; Altun, OğuzhanObjectives: Age estimation plays an important role in forensic medicine and orthodontics. Many methods of age estimation have been suggested. Demirjian method is the most frequently used one of these. In the literature, there is a little known about applicability of this method in Turkish children. The aim of the present study was to evaluate the reliability of Demirjian method of dental age estimaiton and for description of mandibular permanent tooth formation in Turkish children from the southwest Eastern Anatolia region. Materials and Methods: A retrospective study was performed on 1015 panoramic radiographs and 5-15 years of age South western of Eastern Anatolia Regionof Turkish children.

The authors’ study was performed using the cone-beam computed tomography images of 16 to 82-year old 200 (112 female, 88 male) patients (Newton 5G, Verona, Italy). Septum deviation of sphenoid sinus and the distance between 2 ostia were evaluated by coronal and axial sections, respectively. Pneumatization degree of sphenoid sinus, diameter of sphenoid sinus ostium, and distance lower edge of superior turbinate to sphenoid sinus ostium were measured by using sagittal sections. The sellar type was the most common pneumatization type of sphenoid sinus in authors’ study. While the C-type septum deviation was observed as the most common, T-type deviation was the least type. Sphenoid sinus ostium was bilaterally in 71.5% of individuals, and it was not found in 10% of individuals included in the study. A significant decrease was determined in diameter of the left sphenoid sinus ostium with aging. The distances between 2 sphenoid sinus ostia were 7.30 2.77 mm for women and 6.09 2.58 mm for men, respectively. No statistical differences were found in women and men in terms of distances between the lower edge of the right and left superior turbinate and sphenoid sinus ostium on their sides. Consequently, making detailed preoperative radiological evaluation of anatomic variations of sphenoid sinus and sphenoid sinus ostium is important in terms of guiding the surgeon in the process of a successful transsphenoidal surgery.Öğe Detailed anatomical analysis of the sphenoid sinus and sphenoid sinus ostium by cone beam computed tomography(Journal of Craniofacial Surgery, 2016) Yılmaz, Nesibe; Dedeoğlu, Numan; Çolak, Cemil; Özbağ, Davut; Durak, Mehmet AkifThe aim of this study is the evaluation of the anatomical structures of sphenoid sinus ostium used as a reference point for transsphenoidal surgery by cone beam computed tomography.

Consequently, making detailed preoperative radiological evaluation of anatomic variations of sphenoid sinus and sphenoid sinus ostium is important in terms of guiding the surgeon in the process of a successful transsphenoidal surgery. Key Words: Cone-beam computed tomography, sphenoid sinus, sphenoid sinus ostium, transsphenoidal surgery The sphenoid sinus is a double sinus located within the body of the sphenoid bone. Sizes, shapes, and pneumatization type vary from person to person. The bony septum that is located in the midline separates the 2 sinuses from each other.1 The sinus was surrounded with many important anatomical structures, neighborhoods internal carotid artery in the lateral wall, optic nerve at the superolateral and pterygoid nerve (The Vidian Nerve) at the base of the spheoid sinus.2 This sinus opens sphenoethmoidal recess by sphenoid sinus ostium that is located in the upper part of the front wall through the sphenoid sinus.3 The diameter of sphenoid sinus ostium is 2 to 3 mm, it is situated 11 to 14 mm above the base level of the sinus, 4 to 5 mm in lateral of nasal septum, 30 degrees above the base of the nose.4–6 The opening of sphenoid sinus ostium is one of the most important points in transsphenoidal surgery for surgeons. The surgical procedure is done by extending this opening. Closed or being in different positions of this opening can cause difficulty during surgical procedures.7 During the endoscopic and surgical transsphenoidal approaches, finding the ostium is not always easy. So the detection of detailed anatomical analysis this natural way and adjacent structures prior to transsphenoidal surgery may reduce complication incidence. The aim of this study is the evaluation of the anatomical structures of sphenoid sinus ostium used as a reference point for transsphenoidal surgery by cone beam computed tomography. At the same time, the anatomical variations and the pneumatization status of the sphenoid sinus were examined using the same method.Öğe The effects of proprioceptive neuromuscular facilitation, myofascial releasing maneuvers and home exercises on pain and jaw function in patients with bruxism(2018) Duman, Şuayip B.; Dedeoğlu, Numan; Altun, Oğuzhan; Çalışgan, Elisa; Talu, BurcuAbstract: To evaluate the effects of proprioceptive neuromuscular facilitation exercises, myofascial releasing techniques and home exercises on temporamandibular joint pain and jaw function in patients with bruxism. This randomized, controlled experimental trial included 52 patients (42 females, 10 males) aged 16 to 50 years (a mean age of 28.9 ± 11.05 years) with bruxism. The patients were separated into 3 groups, as Group 1 (n: 20) treated with proprioceptive neuromuscular facilitation exercises + myofascial release techniques + home exercise, Group 2 (n: 15) treated with myofascial release + home exercise and Group 3 (n: 17), as the control group, treated with the classical methods of occlusal splint, antidepressant drugs and botox. The Visual Analog Scale, Jaw Restriction Scale and Oral Habits Checklist were used to evaluate pain, restriction of jaw movements and bad habits, respectively. All groups were evaluated at the end of 2 weeks and 6 weeks. When the pre-treatment and post-treatment parameters were compared between the groups, a decrease was determined in the parameters of pain, limitation of jaw function, and restriction of oral behavioursin Group1 and Group2 (p = 0.001, p = 0.05, respectively). This decrease was statistically greater in Group 1. No statistically significant difference was determined in Group 3 in respect of resting, active and night pain, limitation of jaw function and restriction of oral behaviour (p>0.05). Proprioceptive Neuromuscular Facilitation Exercises + myofascial releasing techniques + home exercise were found to be effective in reducing pain, improving restriction of jaw movement and oral behaviors in patients with bruxism. As the first such study, the results of this study can be considered to provide important contributions to the understanding and treatment of patients with bruxism.Öğe Evaluation of maxillary sinus anatomical variation and pathologies through cone-beam computed tomography in patients with impacted third molars in the maxilla(2019) Dedeoğlu, NumanAbstract: Aim: The aim of this study was to compare between the frequency of anatomical variation and pathology in the maxillary sinuses having the impacted third molars in the maxilla adjacent to the dental arch and the maxillary sinuses adjacent to the dental arch having the erupted third molars. Material and Methods: A total of 284 cone beam computed tomography (CBCT) images of the maxillary sinuses, 141 of which are adjacent to the impacted third molar teeth in the maxilla, and 143 of which are adjacent to the erupted third molar teeth, were retrospectively evaluated. In the CBCT images, the pathology, septa, accessory ostium, overpneumatization, Haller cell and teeth root relation with sinus were evaluated in each maxillary sinus. Results: There were no statistically significant differences in the frequency of pathology (p = 0.402), septa (p = 0.904) and overpneumatization (p = 0.798) between the maxillary sinuses adjacent to the impacted third molar dental arch and the erupted third molar dental arch. However, there was a statistically significant difference in the frequency of accessory ostium (p = 0.032) and Haller cells (p = 0.025) between the maxillary sinuses adjacent to the impacted third molar dental arch and the maxillary sinuses adjacent to the erupted third molar dental arch. Conclusion: In the present study, the frequency of accessory ostium and Haller cells in the maxillary sinuses adjacent to impacted third molar dental arches of the maxilla was found to be lower than in the maxillary sinuses adjacent to erupted third molar dental arches.Öğe Evaluation of Relationship Between Maxillary Sinus Volume and Nasolacrimal Canal Dimension Using Cone Beam Computed Tomography(2022) Yeşiltepe, Selin; Sağlam, Hande; Duman, Şuayip Burak; Bayrakdar, İbrahim Şevki; Yasa, Yasin; Dedeoğlu, NumanIntroduction: The objective of this study was to evaluate a possible relationship between maxillary sinus volume (MSV) and the diameter and length of the nasolacrimal canal (NC) using cone beam computed tomography (CBCT) data. Methods: In this retrospective study, CBCT scans of 93 patients were evaluated. The maxillary sinuses and NCs were evaluated separately using Fujifilm-Synapse 3D software. 186 measurements of NC and maxillary sinuses were made in 93 patients. Results: The total mean patient age was 38.2 ± 15.2 years. There were no significant differences between genders in terms of MSV, length, and diameter of NC. No statistically significant differences were found between the two sides in terms of MSV, length, and diameter of NC. While a negative correlation was detected between MSV and NC diameter, a positive correlation was found between MSV and NC length. Discussion and Conclusion: As the maxillary sinus medial wall forms the lateral border of the nasal cavity, the recognition and preservation of the nasolacrimal canal is essential for better postoperative results in surgical procedures to be applied to this area. In our study, it was found that as MSV increased, the diameter of the NC decreased and its length increased.Öğe FIVE-YEAR RADIOGRAPHIC FOLLOW-UP OF ASYMPTOMATIC IMPACTED THIRD MOLAR TEETH WITH COMPLETED APICAL ROOT DEVELOPMENT(2023) Dedeoğlu, Numan; Özen, Duygu ÇelikThird molar teeth can stay impacted due to systemic factors, space deficiency, pathology or an anatomical obstacle. The positions, angles, follicle sizes, and impaction statuses of impacted third molars can change over time. The purpose of this study is to investigate changes in the position, inclination, angle, and follicular width of impacted third molars at the end of a 5-year follow-up on panoramic radiographs. Retrospective analyses of a total of 98 impacted third molar teeth were carried out on panoramic radiographs taken at 5-year intervals for 31 patients who presented to the Department of Oral and Maxillofacial Radiology at Faculty of Dentistry for various reasons between 2013 and 2021.The mean angle of the examined impacted third molars with the occlusal plane was 26.725±27.31° at the beginning of the 5 -year follow-up and 26.399±28.46° at the end of the follow-up. There was a 5° angular change (inclination) in 4(8.2%) impacted molars. In the examinations of the panoramic radiographs taken at 5-year intervals, no pathologic change around any impacted third molar or resorption in neighboring teeth was observed. There were inclination changes in 2(4%) of the impacted molars and position changes in 11(22.4%).The changes may be occur in the position, inclination, angle, and follicular width of asymptomatic impacted teeth in time. It is important that asymptomatic impacted teeth can be followed radio graphically to evaluate the effects of changes in position, inclination, angle and follicle width over time on the impacted tooth and surrounding tissues and to prevent complications that may occur after a possible impacted third molar extraction.Öğe IN TURKISH LABOUR LAW WORK-LIFE BALANCE REGULATIONS TO PREVENT PARENTAL UNEMPLOYMENT(2019) Dedeoğlu, NumanAbstract:The responsibility for the children becomes at the top of a person’s responsibilities towards his family. In Turkey, often mothers fall outside of working life to look after their children. Especially in single-parent families, harmonization of work and family life is difficult and this leads to either unemployment or inefficiency. Work-life balance means for employees achieving a balance between job responsibilities, personal and family responsibilities. Work life and family life’s mutual intervention to each other reduces the quality of life. It also reduces efficiency and performance. For this reason, in order to prevent parental unemployment, arrangements to ensure the work-life balance can help prevent staying home to look after their children. In this regard, the government, trade unions and employers are all responsible. In solving this problem, we should look for different perspectives on flexible working; revise family friendly policies at the community level and must make new arrangements in this issue. This chapter informs about concepts of work-life balance and work-life quality which provide work and employee’s productivity. Maternity leave, paternity leave and parental leave issues in Turkish labour law are examined in this study. This is followed by implementation recommendations to policy-makers.Öğe İnönü üniversitesi Dişhekimliği Fakültesine başvuran hastalarda taurodontizm görülme prevalansının retrospektif olarak değerlendirilmesi(Cumhuriyet Dental Journal, 2014) Umar, Esma; Altun, Oğuzhan; Dedeoğlu, NumanÖz: Amaç: Bu çalışmanın amacı İnönü Üniversitesi Diş Hekimliği Fakültesine başvuran hastalarda taurodontizm prevalansını belirlemek, lokalizasyonu, dağılımını, cinsiyetler arasındaki farklılığını incelemektir.

Yirmi sekiz günlük deney süresinden sonra ratların ağırlık ölçümleri yapıldı, ardından denekler derin anestezi altında sakrifize edildi. Tüm ratların alt sağ-sol çeneleri radyolojik kemik yıkımlarının belirlenmesi amacıyla alındı. Ayrıca tüm deneklerin kan serumlarından kortizol değerleri biyokimyasal analiz ile belirlendi. Veriler ortalama ve standart sapma kullanılarak ifade edildi. Verilerin istatistiksel analizinde student-t testi kullanıldı. Bulgular: Radyolojik kemik yıkımı analizleri sonucunda meziyal ve distal kemik yıkımı yüzdeleri açısından gruplar arasında istatistiksel bir fark tespit edilmedi (P>0.05). Stres grubunun ağırlık ortalamaları kontrol grubundan düşük tespit edildi (P<0.05). Kan serum kortizol değerleri stres grubunda kontrol grubuna göre yüksek tespit edildi (P<0.05). Sonuç: Radyolojik verilere göre 28 günlük kısıtlama stresinin periodontal doku yıkımı üzerinde bir etkisi tespit edilememiştir. Ayrıca kısıtlama stresi deneklerde stres belirteci olan serum kortizol düzeylerinde artışa neden olmuştur ve bir diğer stres belirteci olan kilo kaybına yol açmıştır. Başlık (İngilizce): The Investigation of the Effects of The Restrain Stress on Periodontal Tissue Loss in Ligature Induced Periodontitis in Rats Öz (İngilizce): Objective: The aim of this study is to investigate the radiological and biochemical examination of periodontal tissue destruction in ligature induced experimental periodontitis in restrain stress model. Materials and Methods: Twenty adult female Spraque Dawley rats weighing 390-450 grams were included in the study. Rats were divided in two groups; controls (n =10) and stress (n = 10). At the beginning of the study, rats weights were measured. Ligatures were placed around both left and right mandibular first molars subgingivally of the all rats in general anesthesia. Control group rats were not subjected to any additional treatment during the 28-day experimental period and stress group rats were applied restraint stress 2.5 hours per day. After a period of 28 days of experimentation, the rats were sacrificed in the deep anesthesia following weighing. Both left and right mandible of all rats were taken to determine the radiological bone destruction. In addition, cortisol levels of blood serum of all rats were determined by biochemical analysis. All datas were shown using with mean and standard deviation. Results: After the radiological analysis no statistically significant difference was not detected between controls and stress groups in mesial and distal periodontal bone destruction percentages (P>0,05). The mean weight of the stress groups is lower than controls (P<0,05). Blood cortisol values are detected as higher in stress group when compared with the controls (P<0,05). Conclusion: According to the radiological analysis, 28 day restrain stress did not effect the periodontal tissue destruction. In addition, restraint stress caused an increase in serum cortisol levels, which is a stress indicator in rats, and also weight loss, which is an other stress indicator.Öğe Radiographic evaluation of third molar development in relation to the chronological age of Turkish children in the southwest eastern Anatolia region(Forensic Science International, 2013) Karataş, Orhan Hakkı; Öztürk, Fırat; Dedeoğlu, Numan; Çolak, Cemil; Altun, OğuzhanTo study the chronological age of third-molar mineralisation of Turkish children from the southwest Eastern Anatolia region, the Demirjian staging method was used to determine the stage of the mineralisation of four third molars (18, 28, 38 and 48) and to compare third-molar development by sex and age with the results of previous studies. The study comprised 832 Turkish children from the southwest Eastern Anatolia region aged 6–16 years based on radiological evidence from digital orthopantomograms. The mean age of the 832 patients was 11.03 1.98 years, with 424 males (mean age, 10.97 1.97) and 408 females (mean age, 11.09 2.00). The orthopantomograms were scored by two observers. The Wilcoxon matched-pairs signed-rank test used to assess intra- and inter-observer assessment revealed strong agreement between both observers’ measurements. Statistical analysis of the association between sex and age was performed with the Mann–Whitney U-test and the Wilcoxon test. Regression analysis was performed to obtain regression formulae for calculating the dental and the chronological age. The statistical analysis showed a strong correlation between age and third-molar development in males (R2 = 0.61) and females (R2 = 0.63). New equations (age = 7.49 + 0.69, development stage (DS) 38 + 0.70, DS18) were derived for estimation of the chronological age. The results showed that there was no significant difference in mineralisation between 18 and 28 and 38 and 48 in males or females. For both sexes, the dental age was lower than the chronological age. Males reached the developmental stages earlier than females. In the whole population, the boys’ and the girls’ dental ages were 0.84 years and 0.16 years earlier, respectively, than their chronological ages. The use of third-molar teeth as a developmental marker is suitable, particularly when comparing the obtained standard deviation with other skeletal-age calculation techniques.Öğe Using the fractal dimension method to assess ossification after open sinus lift surgery(2022) Sancar, Bahadır; Dedeoğlu, Numan; Çetiner, Yunus; Aral, Cüneyt Asım; Altun, OguzhanObjective: The present study aims to use the fractal dimension method to assess ossification occurring in patients undergoing an open sinus lift surgery performed with the use of xenograft. Material and Method: In our study, we used 90 orthopantomographs of a total of 43 patients. Our study consists of three groups: Group A, Group B, and Group C. Using the fractal dimension method, we assessed the orthopantomographs taken within three to six months after the open sinus lift surgery (Group A), taken after six to nine months after the open sinus lift surgery (Group B), and taken more than nine months after the open sinus lift surgery (Group C). The data were analyzed using IBM SPSS V23. The compliance of the data with the normal distribution was examined using the Shapiro-Wilk test. Result: The three-way statistics made between the mean values of the groups revealed a difference (p=0,033). The density of the xenograft material in the study area tended to decrease starting from the period of three to six months after the surgery. Conclusion: The fractal dimension method can be used to assess ossification occurring after open sinus lift surgery that is performed with the use of xenografts.Öğe Yaşlılardaki diş kayıplarının ve alveol kemiği rezorbsiyonlarının radyografik değerlendirmesi(Cumhuriyet Dental Journal, 2012) Eltas, Abubekir; Altun, Oğuzhan; Dedeoğlu, Numan; Yavuzer, DuyguÖz: Amaç: Bu çalışmanın amacı Türk toplumundaki yaşlı bireylerin ağız ve dişeti sağlığını belirlemekti.
