Öğe Assessment of correlation between hand-wrist maturation and cervical vertebral maturation: a fractal analysis study(2023) Eninanç, İlknur; Çoban Büyükbayraktar, ZeynepBackground To investigate whether fractal dimension (FD) measurements from hand-wrist radiographs and lateral cephalometric radiographs are correlated with each other and with skeletal maturation stages. Methods In this retrospective study conducted on hand-wrist and lateral cephalometric radiographs obtained from patients between 2017 and 2023, hand-wrist maturation stages (HWMS) and cervical vertebral maturation stages (CVMS) of 144 subjects (6 to 17 years of age) were assessed radiographically. The participants were divided into nine groups (n = 16 each) based on HWMS. Fractal analysis was performed on the radiographs of the radius, the middle finger phalanges (proximal, medial and distal), and the cervical vertebral bodies (C2, C3, C4). Mean and standard deviation values, Spearman’s and Pearson correlation analyses, one-way ANOVA, Kruskal-Wallis H tests and Mann- Whitney-U test were used to evaluate the data. Results Positive correlations were found between the FD values of the radius and HWMS or CVMS (r = .559, P = .001, r = .528 P = .001 respectively). The FD values of the radius were positively correlated with those of all cervical vertebrae (C2, C3, C4), proximal and medial phalanges as well as age. FD values measured from the proximal phalanx, medial phalanx and radius showed significant differences among both HWMS and CVMS (P < .05). HWMS was strongly correlated with CVMS (r = .929, P = .001). Age was strongly correlated with HWMS (r = .795, P = .001) and CVMS (r = .756, P = .001). There was a significant difference in terms of age distribution among HWMS and CVMS (P < .05). Conclusions FD measurements on hand-wrist radiographs can provide useful information for the assessment of skeletal maturation stage. Especially, FD measurements from the radius are important and more reliable to predict skeletal maturation stage.Öğe Bullous Type Lichen Planus: A Rare Case Report(2022) Eninanç, İlknur; Şahin, Büşra; Goze, Omer FahrettınObjective: Oral bullous lichen planus (BLP) is an uncommon form of lichen planus that affects just 1% of the oral mucosa. It is seen in oral mucous, palate, buccal mucous, and occasionally in the tongue. The purpose of this case report is the importance of including lichen planus in the differential diagnosis of leukoplakia-like lesions.Case: The presentation included lateral parts of the tongue, sublingual, and hyperkeratotic areas on the cheek, as well as asymptomatic bullous lichen planus phenomena, clinical and histological characteristics that have been present for 5 years. Systemic corticosteroid was given to the patient who had no skin symptoms. Conclusion: Burning sensation, the BLP's common clinical symptom, which is infrequently observed in the oral mucosa, may not be visible in all patients. In addition, BLP can be confused with leukoplakia when observed in plaque form. Histopathological examination is mandatory for definitive diagnosis in terms of malignant potentialÖğe Comparative assessment of the accuracy of Cameriere’s third molar maturation index method among three different radiographic techniques in a Turkish population(2023) Çakan, Kübra Nur; Yeler Yalçın Defne; Eninanç, İlknurAge estimation of living or deceased individuals can be done for ethical, social and legal purposes and is of paramount importance in forensic medicine. Teeth play a crucial role in age estimation. Third molars can be used for dental age estimation as they are the only teeth still developing at the legal age of 18 years. The aim of this study was to compare the accuracy of Cameriere’s third molar maturation index method when used with panoramic, periapical and cone beam computed tomography imaging techniques and to test its applicability. The study sample included 101 panoramic radiographs, 101 periapical radiographs and 100 CBCT images from 302 individuals aged 14–24 years. Sensitivity, specificity and accuracy of Cameriere’s third molar maturation index method were 71%, 97% and 83.1% for panoramic radiographs, 75%, 87.2% and 81.1% for periapical radiographs, and 61.9%, 100% and 72.7% for CBCT images, respectively. Although the cut-off value of 0.08 was applicable for both sexes, it provided more accurate results in males. Although all three imaging methods were acceptable, Cameriere’s third molar maturation index method provided the most accurate results on panoramic images in the Turkish population studied.Öğe COMPARISON OF RADIOMORPOMETRIC INDEX MEASUREMENTS IN THE MANDIBLE OF COMPLETELY EDENTULOUS ELDERLY AND MIDDLE-AGED INDIVIDUALS(Ümit Muhammet KOÇYİĞİT, 2022) Eninanç, İlknur; Hergüner, TuğbaObjective: The present retrospective research aims to investigate the effect of sex and age on radiomorphometric indices that enable the evaluation of changes in the mandible in elderly and middle-aged edentulous individuals. Materials-Methods: One hundred twenty-eight edentulous individuals (64 females, 64 males) aged 45-54, 55-64, 65-74, and 75-84 years were divided into four age groups. The mental index (MI), panoramic mandibular index (PMI), mandibular cortical index (MCI), and alveolar ridge resorption degree in the premolar regions (M/M ratio) of these individuals were assessed with regard to age and sex on panoramic radiographs. Results: A significant increase was detected in the MCI class with increasing age (p0.05). MI and PMI values in middle-aged and elderly individuals were affected by sex, and these values were found to be lower in females (p0.05). It was observed that the MCI class was lower in females in the 45-54 age group (pÖğe Dijital panoramik radyograflarda bruksist bireyler ile kontrol grubunda mandibular fraktal boyut ve radyomorfometrik indeks değerlerinin incelenmesi(Sivas Cumhuriyet Üniversitesi, 2020) Eninanç, İlknur; Yeler, Defne YalçınBruksizm, çiğneme ve yutkunma gibi fonksiyonlar haricindeki diş sıkma ve/veya gıcırdatma ile karakterize olan parafonksiyonel bir aktivitedir. Gün içinde ve gece istemsizce yapılan bu aktivite sonucu mandibula uzun süreli ve kuvvetli ısırma kuvvetlerine maruz kalmaktadır. Geometrideki kare, daire, üçgen gibi bilindik ve basit şekillerle tanımlanamayan, farklı ölçeklerden incelendiğinde kendine benzeme özelliği gösteren karmaşık yapılara ise "fraktal" denmektedir. Bu şekillerin veya yapıların karmaşıklık derecesi sayısal olarak fraktal boyut (FB) ile ifade edilmektedir. Panoramik radyomorfometrik ölçümler mandibula trabeküler ve kortikal kemik yapısındaki morfolojik değişiklikleri değerlendirmek amacıyla geliştirilmiştir. Otomatik Doz Kontrol (ADC) özelliği bazı panaromik cihazlara özgüdür ve kişinin kemik yoğunluğunu referans alarak, kişiye özel doz ayarlaması yapan ve bu sayede optimum doz ve görüntü kalitesi sağlayan bir özelliktir. Otomatik doz kontrol özelliği ile alınan panoramik radyograflarda, FB'nin bruksist ve non-bruksist bireyler üzerinde radyomorfometrik indekslerle değerlendirildiği literatürde bildiğimiz kadarıyla bir çalışma yoktu. Kliniğimize başvuran sistemik yönden sağlıklı 126 bruksist, 126 non-bruksist birey (132 kadın ve 120 erkek) çalışmaya dahil edildi. "Muhtemel (probable)" bruksizm tanısı için Pintado ve ark. ile Rompre ve ark.'nın önerdiği seçim kriterlerinin kombinasyonu kullanıldı. Mandibulada sağ-sol kondiler (FB1-8), gonial (FB2-7) ve mandibular 2. premolar ile 1. molar dişlerin apikal bölgeleri arası (FB3-6) ve mandibular kanin ile 1. premolar dişlerin apikal bölgeleri arasından (FB4-5) 45x45 piksel boyutlarında toplam sekiz ilgi alanı (ROI) üzerinde White ve Rudolph'un yöntemine göre fraktal analiz uygulandı. Ayrıca mandibular kortikal kemik üzerindeki değişiklikler araştırılmak üzere mandibular kortikal indeks (MKİ), mental indeks (Mİ), panoramik mandibular indeks (PMİ) değerlendirildi. Çalışmada bruksist bireylerin gonial bölgelerden hesaplanan ortalama FB değerlerinin (FB2-7), kontrol grubuna göre anlamlı olarak daha düşük olduğu görüldü (p<0.05). Diğer bölgeler arasında fark yoktu (p>0.05). Cinsiyet ve FB ilişkisine bakıldığında, bruksist ve kontrol grubu bireylerde sağ ve sol kondiler bölgelerde (FB1-8), ayrıca kontrol grubunda FB3 ve FB4 bölgelerinde kadınların FB değerlerinin erkeklere göre anlamlı olarak daha düşük olduğu tespit edildi (p<0.05). MKİ değerleri açısından gruplar arasında fark yoktu (p>0.05). Cinsiyet ile MKİ arasında bir karşılaştırma yapıldığında ise her iki grupta da kadınlarda erkeklere göre istatistiksel olarak anlamlı oranda daha fazla C1 tipine rastlandı (p<0.05). Bruksist bireylerin ortalama Mİ değerleri kontrol grubundan önemli oranda daha yüksekti (p<0.05). Mental indeks ortalamaları cinsiyete göre karşılaştırıldığında ise her iki grupta da kadınlarda anlamlı olarak daha küçük bulundu (p<0.05). Gruplar arasında PMİ değerleri karşılaştırıldığında ise fark önemsizdi (p>0.05) Sonuç olarak mandibular trabeküler kemiğin FB değerleri gonial bölgede bruksizmden, kondil ve dişli bölgelerde ise cinsiyet farklılığından etkilenmektedir. Bruksizmde mandibular kortikal kemik kalınlığı artmaktadır. Cinsiyet mandibular kortikal kemik kalınlığı ve morfolojisinde etkilidir.

Materials and Methods: A total of 305 volunteer students from X University Faculty of Dentistry participated in the study. A questionnaire consist of 44 open-ended and multiple-choice questions was sent to the students. Career plans, specialization preferences and the factors affecting them were questioned in the survey for the periods of before and during Covid-19. Results: With the Covid-19 pandemic, 23.3% of the students changed their career plan and 24.6% of them changed their field of specialization. Regarding the results of this present study, choice of private practice was preferred for career planning after the pandemic. The specialty of choice before the pandemic was Oral and Maxillofacial Surgery whereas the department with the highest increase after the pandemic was Endodontics. Conclusions: The Covid-19 pandemic affected the career and specialty preferences of dental students. Factors such as working conditions, financial return, and employment opportunities, rather than aerosol and increased risk of contamination, were effective in this change. © (2023), (Cumhuriyet University Faculty of Dentistry).

Materials and Methods: 400 adults aged 17-60 years were examined in terms of probable bruxism using the bruxism survey and clinical examination findings. The survey method was used to evaluate the correlation of bruxism with gastroesophageal reflux, gastric ulcer, gastritis, migraine, antidepressant use, cigarette consumption, alcohol consumption, caffeine consumption, and marital status between bruxist and control groups. Results: It was found that gastroesophageal reflux, gastric ulcer, migraine, antidepressant use, caffeine consumption, and cigarette consumption were significantly higher in bruxists (P=.000, P=.004, P=.000, P=.000, P=.000, and P=.008, respectively). No significant difference was observed between bruxist and control groups in terms of the presence of gastritis, alcohol consumption, and marital status (P=.163, P=.221, and P=.913, respectively). While presence of migraine (P=.041) was higher in bruxist females, cigarette and alcohol consumption was higher in bruxist males (P=.000 and P=.001, respectively). Conclusions: In conclusion, it was determined that medical disorders such as gastroesophageal reflux, gastric ulcer, and migraine as well as antidepressant use and cigarette consumption and caffeine consumption were risk factors associated with bruxism. If dentists are aware that these risk factors may cause or exacerbate bruxism, this may be beneficial in preventing damage to the mastication system before it occurs, and in planning treatment correctly. © This work is licensed under Creative Commons Attribution 4.0 International LicenseÖğe Importance of Digastric Muscle Sensitivity in Bruxism(2023) Eninanç, İlknur; Yalçın, DefneObjective. It was aimed to assess the differences in the sensitivities of masticatory and digastric muscles during examination because of continuous and excessive forces in case of bruxism. Material and Method. From the masticatory muscles of 162 individuals with bruxism and 162 control individuals, masseter, temporalis, medial / lateral pterygoideus muscles and digastric muscles were examined. Perceived sense of discomfort-pain during muscle examinations was scored according to a numerical rating scale and recorded as right and left. Results. In individuals with bruxism, the pain scores of the patients for each examined muscle were higher than the control group (p<0.05). In the ROC analysis performed in bruxism, cut-off values for digastric muscle, lateral pterygoideus muscle and other muscles were 2.5, 1.5 and 0.5, respectively. The sensitivity and specificity of the digastric muscles were found to be higher than other muscles (sensitivity: right=72.8%, left=72.8%, specificity: right=18.5%, left=17.9%). Conclusion. Bruxism affects digastric muscles more than masticatory muscles. Digastric muscles and other masticatory muscles should be evaluated in addition to masseter muscle pain, hypertrophy and fatigue in the clinical diagnosis of bruxism.Öğe Is There A Relationship Between Chewing Side Preference and Brain Laterality in Bruxers and Non-Bruxers?(Ordu University, 2023) Kartal, Özge; Yeler, Defne; Eninanç, İlknur; Yeler, Hasan; Gültürk, EsraObjective: There is no consensus on the etiology of unilateral mastication. While some studies argue that environmental factors such as missing teeth, teeth with restoration, pain, dental caries and temporomandibular disorder affect chewing side preference, others claim that brain laterality associated with hand, foot, ear and eye preferences also influences a chewing side preference. The aim of this study was to evaluate the relationship between the direction of unilateral chewing preference and brain laterality in fully dentate bruxers and non-bruxers (fully dentate or with missing and/or restored teeth). Methods: Brain laterality of the subjects (n=132) was determined based on responses to questions about extremity and sensory preferences. The reliable visual analogue scale (VAS), Kazazoglu’s method and the sunflower seed shell cracking test were used to determine chewing side preference (CSP). Results: CSP as determined by VAS was not associated with brain laterality. While extremity and sensory preferences were predominantly right-sided (dominant left hemisphere) in all groups, the frequency of the left-side chewing was found to be high only among bruxers (p>0.05). No significant association was found between the results of VAS and other techniques (p>0.05). Conclusion: The left-side CSP is observed more commonly in bruxers, suggesting that different central and peripheral mechanisms may be involved in bruxers.Öğe MAKSİLLOFASİYAL BÖLGEDE ULTRASONOGRAFİK GÖRÜNTÜLEMEDE GÜNCEL YAKLAŞIMLAR(2023) Eninanç, İlknur1. Ultrasonografinin Tarihçesi ve Genel Bilgiler Ultrasonografi (USG), tıpta ve diş hekimliğinde kullanılan, iyonlaştırıcı radyasyon içermeyen, non-invaziv, düşük maliyetli ve kolay uygulanabilir bir görüntüleme yöntemidir. Ultrasonun temel ilkeleri ve uygulamaları ilk olarak 1880’de Pierre ve Jacques Curie kardeşler tarafından keşfedilmiştir ve ultrason (US) görüntüleme tekniği 1937’de Dussik kardeşler tarafından tanımlanmıştır (Joshi, Pol, & Sudesh, 2014). Tıbbi anlamda USG Avusturyalı nörolog Dr. Karl Theo Dussik tarafından, ilk defa hipersonografi cihazıyla beynin ventriküler sisteminin incelenmesinde kullanılmıştır (Edler & Lindström, 2004). Diş hekimliğinde ise 1963 yılında Baum ve ark. tarafından tanısal USG cihazıyla 15 MHz dalga boyu kullanılarak ilk kez dişlerin iç yapıları görüntülenmiştir (Baum ve ark., 1963).Öğe Malignant Melanoma(2020) Eninanç, İlknur; Yeler, Defne Yalçın; Akçay, Tuğba Kaya; Eğilmez, Hatice ReyhanMalignant melanoma in oral cavity is a rare tumor withaggressive prognosis. Diagnosis may be delayed because it is asymptomatic. In this article, we reported a case of oral malignant melanomaand clinical findings in a 82-year-old male patient. There was a reddish-blue, ulcerous, bleeding and painless mass on the hard palate. Thismass was formed in 3 weeks.Öğe Odontojenik Miksoma(2023) Eninanç, İlknur; Yılmaz, Yasemin MerveOdontojenik miksoma (OM), odontojen ik mezenşimden kay- naklanan, iyi huylu, lokal invaziv bir tümördür. Çene kem iklerinde nadir görülmekle birlikte, odontojenik tümörlerin %3-6’sını oluşturur. Radyografik olarak uniloküler radyolüsent lezyondan, septalarla ayrıl- mış multiloküler radyolüsent lezyona kadar çeşitli tiplerde görülebilir. Sıklıkla mandibula posteriorda rastlanılan tümör, ço ğu zaman bel irti vermeden büyür ve rutin dental muayenelerde tespit edilebilir. Radyo- grafik olarak genell ikle multiloküler izlenen tümörün benzer görüntü veren ameloblastoma, odontojen ik keratokist, anevrizmal kemik kisti gibi diğer tümöral oluşumlardan ayrımı iyi yapılmalıdır. İleri görüntü- leme teknikleriyle yapılan incelemeler tanıya gitmede büyük fayda sağ- lamaktadır. Bu olguda, OM’nin diğer benzer odontojenik tümörlerden radyografik ve klinik özellikleri ile ayırıcı tanısı hakkında bilgi vermek amaçlandı.
