    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.
