    A novel approach to radiographic detection of bucco-palatal/lingual dilacerations: A preliminary study with ImageJ
    (Sage Publications Ltd, 2021) Satir, Samed; Buyukcavus, Muhammed Hilmi; Orhan, Kaan
    The purpose of our study is to determine whether bucco-palatal/lingual (BPL) root dilacerations (RD), especially in single root teeth, can be determined using the ImageJ program through only one periapical radiography. Extracted teeth without any RD (n = 8) were determined as the control group (Group 1) and with RD in apical 1/3 part at least 20 degrees with the longitudinal axis in the BPL direction (n = 8) as the study group (Group 2). With the help of a simple holder system prepared, digital periapical radiographs of all teeth were taken in an anteroposterior position. Histogram analysis of all periapical radiographs was performed using the spectrum feature of ImageJ software. It was aimed to make a dilaceration analysis by comparing the groups using mean, standard deviation, minimum, maximum, and bin width values. As a result of the Mann-Whitney U test, all mean and maximum values showed a statistically significant difference between the study and control groups (p < 0.05). This pilot study revealed that the ImageJ software can be used to diagnose BPL dilaceration in the apical 1/3 part of the root. It is important for dentists and patients that it can contribute to limiting the radiation dose to which patients will be exposed.

    Comparison of Play Dough and Bread Dough with Ballistic Gel as Soft Tissue Simulator: An Ex-Vivo Study with Sheep's Head as the Gold Standard
    (Pera Yayincilik Hizmetleri, 2025) Cimen, Tansu; Saka, Yunus Yigit; Gulsen, Ibrahim Tevfik; Kose, Mehmet Numan; Satir, Samed
    Objective: This study aims to test the usability of bread dough, play dough, and ballistic gel in soft tissue simulations by comparing them with a sheep's head as the gold standard. Cone beam computed tomography (CBCT) images of the sheep's head was obtained as the gold standard. Methods: The sheep's head was re-covered with ballistic gel, play dough, and bread dough, respectively. Two different CBCT images (protocol A-FOV: 8x15cm, 90kVp, 6.3mA, 4.5s, 0.35mm-voxel size, 574 mGy cm(2); protocol B-FOV: 13x15cm, 90kVp, 5mA, 8.1s, 0.30mm-voxel size, 823 mGy cm(2)) were obtained from the gold standard and each simulation model. The Hounsfield unit (HU) feature in the software of the CBCT was used to evaluate gray values. Pearson Correlation Coefficient was used to examine the relationship between variables that comply with normal distribution, and Spearman's rho Correlation Coefficient was used to examine the relationship between variables that do not comply with normal distribution. The significance level was taken as p < 0.05. Results The highest positively significant correlation with the gold standard in the mandible was with bread dough (r = 0.944, p < 0.001), while in the maxilla it was with play dough (r = 0.879, p < 0.001). The highest positive significant correlation with the gold standard in gray values selected from teeth and bone was with ballistic gel (r = 0.762, p=0.004; r = 0.638, p=0.008, respectively), while in pulp it was with play dough (r = 0.874, p < 0.001). A very high, positive, and significant correlation was found between protocols A and B of all simulation models. The highest positive significant correlation of the gold standard protocol A was found with the ballistic gel simulation protocol B (r = 0.893, p < 0.001). Conclusion: Play-dough can be an alternative soft tissue simulator to ballistic gel, especially in ex vivo studies on pulp morphology.

    Diagnosing Pathological Changes in the Non-thickening Sinus Mucosa: A Retrospective CBCT Study with Psudocolor Imaging
    (2023) Satir, Samed; Çimen, Tansu; Gülşen, İbrahim Tevfik; Saka, Yunus Yiğit
    Objective: The aim of this study is to test the utility of pseudocolor imaging in the diagnosis and evaluation of the maxillary sinus mucosa, which has a suspicion of pathological change even though no thickening pattern is formed. Methods: Patients with healthy teeth without apical lesions from premolars and molars adjacent to the right and left maxillary sinus on one side (control) and tooth/teeth with apical lesions on the other side (study) were selected (n=17) and included in the study. Cochran’s Q test was used to compare distribution of color anterior (A), medial (M) and posterior (P). Post-hoc analysis was performed using Bonferroni correction. Results: The rate of multicolor in the anterior and medial side of the pathological side (52.9% and 47.1%) was higher than the healthy side (35.3% and 29.4%), and it was not statistically significant (p=0.300 and p=0.290). Independently of the groups (n=34), the ratio of multicolor in color A (44.1%) was significantly higher than in color P (20.6%) (p=0.047). On the pathological side (n=17), the ratios of multicolor in color A and M (52.9% and 47.1%, respectively) were higher than in color P (23.5%), but this difference was not statistically significant (p=0.148). Conclusion: In implant surgery planning, pseudocolor imaging can be an alternative as a non-invasive adjunctive diagnostic method, especially in the evaluation of the sinus mucosa of maxillary posterior edentulous region in patients with unknown dental history.

    TEMPOROMANDIBULAR JOINT DISEASE AND VITAMIN D LEVEL IN FIBROMYALGIA
    (2022) Satır, Ozlem; Satir, Samed
    Objectives: The aim of our study is to show the prevalence of temporomandibular joint disease (TMD) in fibromyalgia (FM) patients in Turkish population and to evaluate the relationship between vitamin D levels of FM patients with TMD. Materials and Methods: Patients diagnosed FM in the last 4 months were examined in terms of TMD using DC/TMD criteria. By using biochemical data of the patients included in the study, the relationship between vitamin D levels and TMD was interpreted. Results: Among the 39 patients who underwent temporomandibular joint examination (mean age 39,8; age range 18-59), the number of patients with TMD (muscle pain, joint pain, mouth opening limitation, disc displacement, degenerative joint disease) was 30 (29 female, 1 male), while the number of patients without any TMD was found 9 (7 female, 2 male). No statistically significant difference was found between those with TMD and those without TMD in terms of vitamin D (Mann-Whitney U test, D vit p=0,257). Conclusions: Dentists should be aware that patients with widespread pain in the temporomandibular joint area may be candidates for FM and should be careful in evaluating laboratory tests of these patients. The prevalence of TMJ in FM patients and its relationship with vitamin D should be examined with new studies with large patient participation. Öz Amaç: Çalışmamızın amacı, Türk toplumunda fibromyalji (FM) hastalarındaki temporomandibular eklem hastalık (TMEH) prevelensını göstermek ve FM hastalarına ait D vitamini seviyelerinin TMEH ile ilişkisini değerlendirmektir. Gereç ve Yöntemler: Son 4 ay içerisinde FM teşhisi konmuş hastalar DC/TMD kriterleri kullanılarak TMEH açısından incelenmiştir. Yapılan muayene ile masseter ve temporal kasta ağrı, eklem ağrısı, redüksiyonlu/ redüksiyonsuz disk deplasmanı, dejeneratif eklem hastalığı sorgulanmıştır. Çalışmaya dahil edilen hastaların biyokimya verileri kullanılarak D vitamini seviyelerinin TMEH ile ilişkisi yorumlanmıştır. Bulgular: Temporomandibular eklem muayenesi yapılan toplam 39 FM hastasından (yaş ortalaması 39,8; yaş aralığı 18-59) 36’sı kadın 3’ü ise erkektir. Tüm hastalar içerisinde TMEH tespit edilenlerin sayısı 30 (29 kadın, 1 erkek) iken, herhangi bir TMEH bulgusuna rastlanmayan hastaların sayısı 9 (7 kadın, 2 erkek)’dur. TMEH tespit edilen hastaların 26’sında kas ağrısı gözlenmiştir. Kas ağrısı görülmeksizin eklem ağrısı ve dejeneratif eklem hastalığı bulunan sırasıyla 2 ve 1 hasta tespit edilmiştir. TMEH varlığı olanların D vitamini değerleri TMEH varlığı olmayanlara göre düşük olmasına rağmen istatistiksel olarak anlamlı bir farklılık bulunamamıştır (Mann-Whitney U test, p=0,257). Sonuçlar: Diş hekimleri özellikle temporomandibular eklem bölgesinde yaygın ağrı şikâyeti olan hastaların FM hastası adayı olabileceğinin farkında olmalı ve bu hastaların laboratuvar testlerini değerlendirme konusunda dikkatli olmalıdır. Geniş hasta katılımı ile yapılacak yeni çalışmalar ile FM hastalarındaki TMEH prevalansının D vitamini ile olan ilişkisi incelenmelidir.
