Publication Open Access Accuracy of Dental and Chronological Age Estimation in A Sample Turkish Caucasion Children: Comparison of Demirjian’s and Willems Methods(2023-09-01) NAMDAR PEKİNER, FİLİZ MEDİHA; İzgi E., Namdar Pekiner F. M.Objective: The purpose of this study is to apply Demirjian’s and Willems’ methodologies and to define whether there are any discrepancies in predicting dental age versus chronological age in a sample Turkish Caucasian children. Methods: A total of 150 Turkish Caucasian children with known chronological age and gender were chosen. The chronological age was determined by subtracting the date of birth from the date of the radiograph, and it was expressed as a number with two decimal places. Each age group was determined to have a minimum sample size of 12 and a maximum sample size of 27. All panoramic radiographs were scored according to the criteria of Demirjian’s and Willems methodologies with Onyx Ceph 3.1.54 software. Results: The dental ages of the cases ranged from 4.82 to 15.66 years calculated by the Demirjian’s method, with an average of 9.47±2.27 years, while the Willems method of the cases ranged from 4.13 to 14.34 years calculated by the Demirjian’s method, with an average of 8.87±2.24 years. According to Demirjian’s method, in the developmental evaluation of dental age, 45.3% of boys were found to have a statistically higher chronological age than girls (p<.05), while no statistically significant difference was found between dental age and chronological age in developmental evaluation according to Willems method (p>.05). Conclusion: The Willems method was shown to be more accurate in determining dental age in Turkish children. Further studies on large population groups and diverse ethnicities are required to increase the reliability and repeatability of the results.

M.Necrotizing ulcerative stomatitis or Plaut-Vincent’s Stomatitis is a complication of necrotizing ulcerative gingivitis that extends beyond the gingiva and is involved in other parts of the oral mucosa, with Fusiform bacillus, Borrelia vincenti and other anaerobic microorganisms being the most common associated bacteria. It starts with sore throat, bad smell in the mouth, bleeding gums in young adults with poor oral hygiene and decreased immune resistance. In this case, clinical findings of Plaut-Vincent Stomatitis belonging to a male patient are presented. In a 22-yearold male patient, erythematous, ulcers with irregular margins and grayish-white fibrin were observed in the soft tissue of the right third molar region of the mandible and in the buccal mucosa. The patient has halitosis, difficulty in swallowing, pain in the oropharynx, and lymphadenopathy. In the treatment of infected tissues, improvement was observed after systemic antibiotics and hydrogen peroxide mouthwash were applied for 6-7 days. PlautVincent Stomatitis is frequently seen in young adults and poor oral hygiene, smoking, emotional stress, alcohol consumption and malnutrition are stated as etiological factors that predispose to this disease. Detection of ulcerated lesions in soft tissue examination is important in diagnosis and treatment.Publication Open Access A deep learning algorithm for classification of oral lichen planus lesions from photographic images: a retrospective study(2023-02-01) NAMDAR PEKİNER, FİLİZ MEDİHA; KESER, GAYE; Keser G., Bayrakdar İ. Ş., Namdar Pekiner F. M., Çelik Ö., Orhan K.IntroductionDeep learning methods have recently been applied for the processing of medical images, and they have shown promise in a variety of applications. This study aimed to develop a deep learning approach for identifying oral lichen planus lesions using photographic images.Material and MethodsAnonymous retrospective photographic images of buccal mucosa with 65 healthy and 72 oral lichen planus lesions were identified using the CranioCatch program (CranioCatch, Eskişehir, Turkey). All images were re-checked and verified by Oral Medicine and Maxillofacial Radiology experts. This data set was divided into training (n =51; n=58), verification (n =7; n=7), and test (n =7; n=7) sets for healthy mucosa and mucosa with the oral lichen planus lesion, respectively. In the study, an artificial intelligence model was developed using Google Inception V3 architecture implemented with Tensorflow, which is a deep learning approach.ResultsAI deep learning model provided the classification of all test images for both healthy and diseased mucosa with a 100% success rate.ConclusionIn the healthcare business, AI offers a wide range of uses and applications. The increased effort increased complexity of the job, and probable doctor fatigue may jeopardize diagnostic abilities and results. Artificial intelligence (AI) components in imaging equipment would lessen this effort and increase efficiency. They can also detect oral lesions and have access to more data than their human counterparts. Our preliminary findings show that deep learning has the potential to handle this significant challenge.Publication Open Access Xeroderma pigmentosum: Case report(2023-08-01) SADIKOĞLU, AYŞE NUR; NAMDAR PEKİNER, FİLİZ MEDİHA; Güler Dönmez F., Namdar Pekiner F. M., Sadıkoğlu A. N.Aim Xeroderma pigmentosum, which is commonly known as XP, is an inherited condition characterized by an extreme sensitivity to ultraviolet (UV) rays from sunlight. This condition mostly affects the eyes and areas of skin exposed to the sun. Some affected individuals also have problems involving the nervous system. In affected individuals, exposure to sunlight often causes dry skin (xeroderma) and changes in skin coloring (pigmentation). The aim of this report is to present a case of xeroderma pigmentosum in a female patient. Case Report A 33-year-old female patient was referred to Marmara University, Faculty of Dentistry Oral Diagnosis Clinic. A 33-year-old female patient was admitted to Marmara University Faculty of Dentistry Oral Diagnosis Clinic with the complaint of pain. All systemic findings of the syndrome were observed. In the intraoral examination, no findings were found in the oral mucosa. Discussion People with xeroderma pigmentosum have a greatly increased risk of developing skin cancer. Without sun protection, about half of children with this condition develop their first skin cancer by age 10. Most people with xeroderma pigmentosum develop multiple skin cancers during their lifetime. These cancers occur most often on the face, lips, and eyelids. Cancer can also develop on the scalp, in the eyes, and on the tip of the tongue. Conclusion Patients should be kept under control because of squamous cell carcinoma that can be observed in the oral mucosa.Publication Metadata only Dil mukozası ve muayenesi(İstanbul Medikal Yayıncılık, 2022-08-01) NAMDAR PEKİNER, FİLİZ MEDİHA; Namdar Pekiner F. M.Publication Open Access Incidental Radiopaque Lesions in the Jaw Bones: Retrospective Analysis(2024-08-01) NAMDAR PEKİNER, FİLİZ MEDİHA; Öner Talmaç A. G., Namdar Pekiner F. M.Purpose: Among themost used diagnostic techniques is panoramic radiography, which enables us to assess the entire jaw. This retrospective investigation aimed to evaluate the radiopaque lesions in the jaws visible on panoramic radiographs. Materials andMethods: 1108 patients’ panoramic radiographs were used in the investigation. Idiopathic osteosclerosis, condensing osteitis, soft tissue calcification, hypercementosis, periapical osseous dysplasia, odontoma, fibrous dysplasia, fluoride osseous dysplasia and cementoblastoma, were among the radiopaque lesions whose frequency, gender, and localization were assessed in this study. Fisher exact tests, chi-square, and descriptive statistics were employed in the data analysis. Results: 499 (45.03%) of the patients were male and 609 (55.97%) were female. The patients included in the study ranged in age from14 to 83 years, with amean age of 33.45 (± 13.80) years. Of the 1108 patients in this study, 85 (7.7%) had radiopaque lesions. 44 cases (4.0%) of idiopathic osteosclerosis, 13 cases of condensing osteitis, 12 cases of soft tissue calcification, 4 cases of hypercementosis, 3 cases of fluoride osseous dysplasia (0.3%), 3 cases of periapical osseous dysplasia, 2 cases of odontoma, and 1 case of fibrous dysplasia (0.01%) were reported. For any of the lesions, there was no statistically significant variation based on gender. Conclusions: Panoramic radiography, which is now commonly utilized, can be used to examine radiopaque lesions of the jaws. In this study, themost common radiopaque lesion was idiopathic osteosclerosis, while cementoblastoma was not found at all.
