    (2019-04-01T00:00:00Z) Sarica, İRFAN; Derindag, G; Kurtuldu, E; Naralan, ME; Caglayan, F; SARICA, İRFAN
    Objective: The objective of this study is to determine the incidence of impacted teeth and the frequency of pathologies they caused by cone beam computed tomography (CBCT) retrospectively. Materials and Methods: In this study, 608 patients’ CBCT images were analyzed retrospectively. Detected impacted teeth were classified as incisor, canine, premolar, molar, third molar, and supernumerary teeth. The pathologies caused by impacted teeth are classified as cysts or tumors, tooth decay, root resorptions, and periodontal bone loss. Results: Impacted teeth were detected in 34.37% of the 608 CBCT images included in the study. The distribution of impacted teeth was 9.4% incisor, 29.4% canine, 9.9% premolar, 2.9% molar, 9.3% supernumerary, and 39.9% third molar teeth. Approximately 63.7% of the impacted teeth caused a pathology. The pathology that was most commonly caused by impacted teeth was periodontal bone loss (44.4%), and respectively others were root resorptions (33.3%), cysts or tumors (8.6%), and tooth decay (2.3%). The most common cause of this pathology was right mandibular third molar teeth. Conclusion: Impacted teeth were common and they often caused a pathology. CBCT is a useful device to assess the impacted teeth. When the impacted teeth are evaluated, each tooth should be assessed within itself. If the impacted teeth are not caused by pathology, they can be kept under control.

    Examination of oral hemangiomas by intraoral ultrasonography
    (2021-03-01T00:00:00Z) Derindag, Gozde; SARICA, İRFAN; ÇAĞLAYAN, Fatma; SARICA, İRFAN
    Objectives Oral hemangioma is a benign vascular tumor characterized by the presence of numerous blood vessels. We aimed to examine the clinical and ultrasonographic findings of patients diagnosed with oral hemangioma in our ultrasonography (USG) archive, retrospectively. Methods This study was conducted by examining 20 patients diagnosed with oral hemangioma and underwent USG examination in the Department of Oral and Maxillofacial Radiology of Ataturk University Faculty of Dentistry from 2016 to 2020. All patients had intraoral and radiographic examinations. Patients pre-diagnosed clinically oral hemangioma were evaluated as intraoral with USG. The intraoral USG examinations were performed using both the B-mode and the color Doppler mode. Results The mean age of the patients was 42.4 +/- 19.14 years; 16 patients were female and four were male. The lesions were mostly observed on the alveolar mucosa (30%), followed by the buccal mucosa (25%), the lower lip (15%), the mouth floor (15%), the tongue (15%). In intraoral USG examinations of all oral hemangiomas, we detected submucosal located, well-defined, lobulated, non-capsule, hypo-isoechoic, heterogeneous lesion areas. Additionally, while we detected only peripheral blood flow in 6 (30%) of 20 patients, we detected both internal and peripheral blood flow in 14 (70%). Conclusions In our study, the examination of the oral hemangiomas with the intraoral probe and the color Doppler mode was very helpful in the differential diagnosis. Although histopathology has an important place in definitive diagnosis, particularly intraoral USG can provide sufficient information for the diagnosis of oral hemangiomas.

    Mucoepidermoid Carcinoma Is This You?
    (2023-07-08) Gürsoy N.; Kesilmiş E. R.; Sarıca İ.; Alagöz E.; GÜRSOY, NİLÜFER; KESİLMİŞ, EMİNE RANA; SARICA, İRFAN; ALAGÖZ, ELİFHAN
    Aims: Mucoepidermoid carcinoma(MEC) is a malignant tumor which mixture of epidermoid and mucous cells originating from the ductal epithelium of the salivary glands. These cases aim to represent three mucoepidermoid carcinoma in different clinical courses. Materials and Methods: The first patient, 86-year-old, was referred to our clinic with a swelling at left mouth floor and referred with squamous-cell-carcinoma(SCC) pre-diagnosis. The biopsy reported as MEC(Intermediate/High-grade). The second patient, 66-year-old, smoker, visited our clinic with bleeding scar at palatina and referred with SCC pre-diagnosis. Histopathological diagnosis indicated as proliferative verrucous leukoplakia. The biopsy repeated because of recurrence and reported as low- grade MEC. The third patient, 74-year-old, diagnosed with high-grade MEC because of fixed mass in the right mouth floor six years ago. One-year later, radiological changes detected around right upper second molar, suspected as recurrence and biopsy planned. The specimen reported as well- differentiated SCC. Results: In every cases, specific imaging methods should be prefered with histopathological examination for a better diagnosis. In our cases we prefered magnetic resonance imaging, contrast- enhanced computed tomography and positron emission tomography with histopathologic evaluation. Then, all patients were referred to otorhinolaryngology for operation and to oncology service to get radiotherapy. Unfortunately, the first patient passed away one-year later. Conclusion: Clinical examination with radiological assesment may lead us misdiagnosis. In these cases, we clearly see some malignancies can confuse clinicians even pathologs. That’s why we need to asses clinic, radiologic and pathologic evidences together and always should be ready for unexpected.

    Evaluation Of Knowledge, Behavior And Attitude About Radiation Safety And Radiation Protection In Dentistry
    (2023-07-08) Kesilmiş E. R.; Alagöz E.; Sarıca İ.; KESİLMİŞ, EMİNE RANA; ALAGÖZ, ELİFHAN; SARICA, İRFAN
    Aims: Dental imaging is done frequently by x-ray in dentistry practice. Dentists should have knowledge about radiation protection in order to protect themselves, the patients, and the environment from the possible damage of radiation. The purpose of this study is to evaluate radiation security knowledge and behavior and create awareness of these issues among intern dentistry students and dentists. Materials and Methods: 151 intern dentists, 86 dentists, and 83 specialist dentists participated in the survey. The survey was prepared through Google forms. The questionnaire includes questions about the demographic characteristics of the participants, their level of knowledge about radiation safety, and their attitudes and behaviors. Statistical analysis was performed using IBM SPSS Statistics version 28.0(IBM, Chicago, IL). Results: From the participants of the survey; 46.6%(149) chose the rectangular collimator, 20.9%(67) used a 40 cm cone, and 50.3%(161) of them used a parallel technique and preferred to reduce the radiation dose. 46.6%(149) of the participants chose bone marrow as the most radiosensitive tissue. Of the participants, 9.1%(29) of them did not know about the As-Low-As-Reasonably- Achievable(ALARA) principle. It was learned that 33.4%(107) of the participants wanted their patients to hold the film with their own hands during the periapical radiographs. Conclusion: According to the results of the survey, it has been observed that intern dentists and specialist radiologists have a higher awareness of radiation safety compared to dentists and other specialist dentists. However, considering the damage of x-rays to vital tissues, it is found that, this awareness is not sufficient and needs to be increased.

    Examination of the Relationship Between Sella Turcica and Impacted Maxillary Canine Teeth: A Retrospective Study
    (2024-01-01) Açıkgöz G.; SARICA İ.; Bilge N. H.; Akgül H. M.; SARICA, İRFAN
    Objectives: In the present study, we aimed to compare the morphological shape and linear dimensions of the sella turcica (ST) between individuals with and without impacted maxillary canines (IMC). Materials and Methods: Cone-beam computed tomography scans of 120 individuals with IMC (study group) were obtained, retrospectively. This study group was divided into three subgroups: group I (n=40), right IMC; group II (n=44), left IMC; and group III (n=36), bilateral IMC. A control group of 40 individuals without IMC were included in this study from the same archive. The study group was divided into three subgroups: group I (n=40), right IMC; group II (n=44), left IMC; and group III (n=36), bilateral IMC. The shape and the linear dimensions of the ST were evaluated in all groups. Data were analyzed using an independent sample t-test and the chi-square test. The significance level was assigned as p<0.05. Results: The linear dimensions ‒length, depth, and diameter‒ of the ST in the control group were significantly different from those in group I (p=0.050, p=0.001, and p=0.018, respectively), group II (p=0.040, p=0.048, and p=0.006, respectively), and group III (p=0.014, p=0.039, and p=0.007, respectively). In addition, there were no statistically significant associations among ST types in the control and study groups. Conclusions: The length, depth, and diameter of the ST were greater in the control group than in the individuals with unilateral or bilateral IMC. Also, no relationship was found between the morphological shapes of the ST in individuals with and without IMC.
