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 Cone beam computed tomography imaging guides for ortodontic miniscrew placement(2019) Duman, Şuayip Burak; Altun, Oguzhan; Sümbüllü, Muhammed AkifAbstract: The aim of this retrospective study is to present a guide for the clinicians by detecting the best mini screw placement areas with the measurement of cortical bone thickness in the patients who have cone beam computed tomography (CBCT) images. Additionally to be protected from root damage and a potential damage to environmental anatomic tissues, related measurements will also be held in the determined areas.This study has been evaluated by using the images of 52 patients taken by cone beam computed tomography for diagnosis and cure.In the mandibular measurements which were done by using CBCT, the buccal cortical bone thickness has been found out to increase while going towards the posterior region and going down to the apical region at the same area. In addition, it was observed mostly between second premolar and f irst molar teeth at the farthest area from the top of the crest, along the mandibular canal. The distance between base of the nose and maxillar sinus floor to the hill of the crest has also been observed that decreased towards the posterior region.Although it can vary according to the person, in mini screw applications, mandibular cortical bone structure and the interradicular range is more suitable than the upper jaw. To be protected from the potential complications and for a better stability, radiologic analysis is recommended to the patient before the mini screw placement.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 Evaluation of the relationship of temporomandibular disorders and the morphology of the mandible(2021) Sancar, Bahadır; Arıkan, Büşra; Boylu, Omer Faruk; Duman, Şuayip Burak; Dayi, ErtuncTemporomandibular joint disorders (TMD) are among the most common problems in the jaw, face, and ear zones. There are multiple factors in the etiology of TMD. It is considered that its morphology may play a role in the etiology of the disease. This study aimed to evaluate the relationship of temporomandibular joint (TMJ) disorder with condyle length, ramus length, condyle width, corpus length, gonial angle, and ramus/corpus ratio.The study was conducted on a total of 100 patients, 50 were symptomatic and 50 were asymptomatic, aged between 16 and 66 years. Symptomatic patients were selected among the patients who presented to our clinic for at least one of the complaints of crepitation, clicking, and pain in the temporomandibular zone on both sides (bilateral). The control group was selected among asymptomatic patients who did not have any complaints in the temporomandibular zone. We evaluated its relationship with TMD by measuring condyle length, condyle width, ramus length, corpus length, gonial angle, and ramus/corpus ratio on CBCT. In the total population, condyle length, ramus length, and condyle width were longer in favor of the control group. However, there was no difference between the ramus/corpus ratio and corpus length. The width of the condyle in female patients with TMD, and the length of the corpus in male patients with TMD were higher in favor of the control group. There is a relationship between TMD and mandible morphology. Knowing the effectiveness of the morphology of the mandible in TME disorders is important in terms of informing individuals with risky morphology beforehand.Öğe Konik Işınlı Bilgisayarlı Tomografi ile Pontikulus Postikus’un Görülme Sıklığının Değerlendirilmesi: Pilot Çalışma(İnönü Üniversitesi, Diş Hekimliği Fakültesi, Ağız, Diş ve Çene Radyolojisi Anabilim Dalı, Malatya, Türkiye, 2018) Bilgir, Elif; Duman, Şuayip BurakÖz: Amaç: Pontikulus postikus, içinden ver tebr al ar terin geçtiği atlas üzerinde anormal bir kemik köprüdür ve C1 lateral kitle vidası ameliyatı geçirecek hastalarda önemli roloynamaktadır. Buçalışmanınamacı, genelpopülasyonda pontikulus postikus’un görülme sıklığı ve özelliklerini saptamaktır. Gereç ve Yöntem: 108 hastanın konik ışınlı bilgisayarlı tomografi görüntüleri randomize olarak seçildi. Kesitler incelendi. Pontikulus Postikusun normal popülasyonda görülme sıklığı belirlendi. Bulgular: 108 hastanın 10 (% 9,2) ‘unda pontikulus postikus belirlendi. Sonuç: Pontikulus postikus klinik olarak servikal omurga cerrahisinde önemli bir anomalidir. Bu nedenle ameliyattan önce pontikulus postikus’un görülme ihtimali akılda tutulmalıdır.Öğe Surgical removal of a fungus ball formed in the maxillary sinus secondary to surgically assisted rapid palatal expansion procedure during Le Fort I osteotomy(2020) Sancar, Bahadır; Duman, Şuayip Burak; Ünlütürk, BurakAbstract: Surgically assisted rapid palatal expansion (SARPE) is a surgery with a low rate of complications frequently performed in cases of maxillary transverse deficiency. Although fungal infection of the paranasal sinuses is rare in healthy people, this rate rises after the use of antibiotics and steroids, and after invasive interventions of the sinus. In our study, we present surgical removal of aspergillosis formed in the case of an 18-year-old female patient secondary SARPE procedure, with Le Fort I osteotomy. A cone beam computed tomography examination 6 months after the surgical removal of aspergillosis showed no recurrence. In conclusion, we report that aspergillosis may occur secondary to SARPE procedure and can successfully be removed in a single session with Le Fort I osteotomy.
