    Analysis of Maxillary Sinus Anatomical Variations in Cone Beam Computed Tomography for Dental Implants Treatment Plan
    (2025) Karcı, Bilge; Sökmen, Kevser
    Aim: This study aim was to assess the maxillary sinus anatomical variations and structures using cone beam computed tomography (CBCT), particularly for dental implant treatment planning. Materials and Methods: In this cross-sectional prevalence study, 200 CBCT images were examined. The assessments were conducted independently by two authors to evaluate the anatomical variations of the maxillary sinus. The anatomical variations assessed in the axial images included alveolar pneumatization, anterior pneumatization, exostosis, and hypoplasia. Additionally, the positioning of sinus septa and the posterior superior alveolar artery (PSAA) was also evaluated. Results: Among the 400 maxillary sinuses analyzed, alveolar pneumatization was the most commonly detected morphological abnormality. Anterior pneumatization was detected in 84 sinuses (% 21.0). Antral septa were found in 175 sinuses (% 43.7) and were mostly located in the middle region. Among 254 sinuses, the PSAA was most frequently detected intraosseously, accounting for 63.5% of cases. Conclusion: Maxillary sinus anatomical variations are significant findings in the context of dental implant planning. These variations are frequently observed in CBCT examinations conducted on the maxilla. Understanding the anatomical variations of the maxillary sinus enhances the effectiveness of preoperative dental implant planning and aids in the prevention of potential complications.

    Evaluation of the Awareness of Patients Applying to the Periodontology Clinic on Oral Hygiene Habits According to Periodontal Status
    (2025) Sökmen, Kevser
    Aim: The aim of this study is to examine the awareness of patients applying to the periodontology clinic about oral hygiene habits (OHH) according to their periodontal status through a survey. Material and Methods: 400 volunteer patients who applied to the periodontology clinic and were diagnosed with periodontitis (n=200) and gingivitis (n=200)) after clinical and radiographic examination were included in the study. Questionnaires including demographic data and oral hygiene habits were directed to the patients in the form of mutual question-answer. Results: In the gingivitis group, the incidence rate in female individuals between the ages of 18-39, university graduates, non-smokers were found to be statistically higher than in the periodontitis group (p<0.05). In the gingivitis group, the rate of knowing what the bleeding in the gingiva is a symptom of, the rate of brushing teeth twice or more a day, the rate of using electric toothbrushes were found to be statistically higher than the periodontitis group (p<0.05). The rate of using toothpicks in the periodontitis group was statistically significantly higher than the gingivitis group (p<0.05). No statistical difference was found between the two groups in terms of other findings (p>0.05). Conclusion: In line with the results of this study, it has been shown that patients have insufficient knowledge about the use of auxiliary oral hygiene tools other than toothbrushes. It was determined that oral hygiene education and motivation of patients should be provided.
