    Benign and Malignant Neoplasms Affecting Periodontal Tissues: A Retrospective Study
    (Ankara Üniversitesi, 2022) Kurgan, Sivge; Diş Hekimliği; Diş Hekimliği Fakültesi
    Introduction: Oral neoplasms are the second most common oral lesions after reactive proliferative lesions. The aim of this study is to determine the distribution of the oral neoplasms by gender and age, and briefly discussed the clinical manifestations, diagnosis, and treatments of these lesions. Materials and Methods: To collect the study material, a pathological retrospective archive analysis has been performed and 61 oral neoplasm cases were determined in a total of 423 samples. 61 biopsies and clinical data of patients were studied and classified based on their histopathologic diagnosis, age, gender, and frequency. Results: In our study, a total of 61 neoplastic lesions were examined, and the mean age was 45.5 ±18.2. The most common lesion in the oral neoplastic lesion is leukoplakia (n=15, 24.59%). This is followed by squamous cell carcinoma (SCC) (n =13, 21.31%) and squamous papilloma (n =11, 18.03%). The rest are gingival granular cell tumor, hemangioma, odontoma, lipoma, mucosal nevus, myxoma, ameloblastoma, leukemia, melanoma, lymphoma, and osteosarcoma. Conclusion: This study provided important data on the frequency and histological distribution of oral benign and malign neoplasms. This study also highlights the diagnosis, and management of these oral neoplasms for the dentists.

    Comparison of Surgery-Related Knowledge Levels Between Patient Groups with and without Experience of Impacted Tooth Extraction
    (Ankara Üniversitesi, 2022) Gülerci, İrem; Diş Hekimliği; Diş Hekimliği Fakültesi
    Purpose: Comparison of the knowledge levels of patients in different demographic groups with and without impacted third molar experience. The authors' expectation was that experienced patients would have a higher level of knowledge. Materials and Methods: Sixty-five patients (34 experienced, 31 inexperienced) with impacted third molar extraction indication were included in the study. A questionnaire with 23 questions concerning different operative phases and where the patients could write down their own questions were administered before surgeries. Demographic data (gender, age group and educational status) were also noted. Results: Questionnaire success did not show a significant difference in different demographic groups and between patients with and without experience of third molar tooth extraction (p>0.05). Conclusion: Dental surgeons should do their best to provide written and verbal information before surgical procedures, each patient should be evaluated as a first-time patient, regardless of demographic data and past experiences. It should not be neglected to provide a detailed information process.

    In-Vitro Bond Strength of a Flowable Compomer to Primary Teeth Dentin with Different Applying Techniques
    (Ankara Üniversitesi, 2022) Zincir, Bahar; Diş Hekimliği; Diş Hekimliği Fakültesi
    Purpose: The study aimed to investigate the effect of applying flowable compomer using different techniques and long-term water storage on microtensile bond strength (µTBS) to primary teeth dentin and present a comparison with packable compomer. Materials and methods: 90 primary molars were used to evaluate the µTBS of the materials. Specimens were randomly divided into 3 main groups for restoration: Group 1 and 4, compomer (Glasiosite, VOCO GmbH, Cuxhaven, Germany) filling alone; Group 2 and 5, flowable compomer (Twinky Star Flow, VOCO GmbH, Cuxhaven, Germany) lining/pre-cured and overlaying compomer; and Group 3 and 6, flowable compomer lining/co-cured with overlaying compomer. All specimens were thermocycled (500X), after which half of them (n=45) were stored in distilled water for 24 h (Group A: Groups 1-3), and the remaining half (n=45) for 24 months (Group B: Groups 4-6). Samples were tested for µTBS (1 mm/min) with a microtensile testing machine (T 61010 Ki, Bisco, Schaumburg, USA). Failure modes were determined with the aid of a stereomicroscope. Results were analyzed using the Kruskal-Wallis H test. Results: There was no statistically significant difference between the groups regarding bond strength (p>0.05). Mixed cohesive failure of both adhesive and dentin was the most common type of failure in all groups (p<0.05). 2-year water storage significantly decreased the bond strength for all groups (p<0.05). Conclusion: Flowable compomers applied using different techniques produced similar bond strength to dentin compared to compomer. However, long-term water storage decreased bond strength significantly.
