Public knowledge about oral cancer may help to prevent and detect the disease at an early stage. This study aimed to evaluate the awareness and knowledge levels on oral cancer symptoms and risk factors among patients attending a faculty of dentistry in North Cyprus. A total of 250 adult dental patients participated voluntarily in a self-administered questionnaire. The questionnaire included questions on sociodemographic profile, oral cancer awareness, and knowledge. A total of 54.8% of the participants were male and 91.2% of the participants had a high school diploma and above education. Most participants were knowledgeable about oral cancer symptoms and a majority of them identified oral ulceration (64%). Tobacco cessation was the most selected option for protecting from oral cancer (79.6%). Significant differences were found between genders in current smokers, past tobacco users, alcohol users, and HPV awareness questions (p < 0.05). Furthermore, awareness and knowledge questions were compared between smoker and non-smoker participants and significant differences were found in the answers of ‘alcohol may cause mouth cancer’ and ‘quit tobacco use to prevent oral cancer’ (p < 0.05). This study showed that most of the participants were aware that tobacco cessation reduces the risk of oral cancer. The survey results showed that patients in North Cyprus are generally aware of the risk of tobacco-related oral cancer, but they demonstrate lower knowledge about other risk factors.
Objective. This web-based survey, as a tool of teledentistry, is aimed at assessing the level of knowledge, attitudes, and awareness regarding MRONJ among dental professionals in Northern Cyprus. Methods. An online self-administered questionnaire about MRONJ was sent to all dentists in Northern Cyprus through Google Forms. The first part of the questionnaire consists of demographic and professional information, and the second part included questions about knowledge and awareness questions about MRONJ. The SPSS software was used for statistical data analysis. A Chi-square test was performed to compare between the groups. The significance level was set at
p
<
0.05
. Results. A total of 112 dentists participated in this survey. The participants showed an insufficient level of knowledge regarding MRONJ, as only 56.6% of the participants stated that they had general knowledge about MRONJ. Regarding the practical questions of the survey, the participants showed poor knowledge about implant and tooth extraction procedures while a patient is using antiresorptive or antiangiogenic drugs, particularly the usage of oral antiresorptive or antiangiogenic drugs for less than 3 years. Participants showed adequate knowledge in terms of usage area of medications and administration of them. Conclusion. Teledentistry can be used as a supportive tool for dentists in diagnosing MRONJ. Similar to previous studies, the knowledge and awareness of MRONJ of dentists in Northern Cyprus were found to be inadequate. There is a significant need to provide more professional information as part of undergraduate programs so that the next generation of dentists can practice more confidently.
Purpose. This study aimed to compare the presence and grades of intra- and extracranial carotid artery calcifications between obstructive sleep apnea (OSA) and non-OSA patients. Methods. CBCT records of 190 patients (95 OSA patients and 95 non-OSA patients) were retrospectively collected and analyzed. Patient demographic data, including age and gender for both study groups and body mass index (BMI), and apnea-hypopnea index (AHI) for OSA patients were recorded. The presence of intra- and extracranial carotid artery calcifications and the number of calcifications were noted according to the grading scale. Results. There was a significant difference in carotid artery calcifications between OSA patients and healthy individuals. A total of 56.8% of the OSA patients showed at least one carotid artery calcification, whereas 13.8% of healthy individuals showed at least one carotid artery calcification (
p
<
0.05
). For intracranial calcifications, OSA patients showed a significantly higher prevalence than healthy individuals (
p
<
0.05
). The results showed that as the apnea-hypopnea index increases in OSA patients, the incidence of carotid artery calcification increases simultaneously. AHI > 30 patients showed the highest percentage of calcifications. Conclusion. In conclusion, OSA patients showed a higher prevalence of calcified carotid artery calcifications than healthy individuals. The results can be interpreted as the higher AHI, the more carotid artery calcification occurs. As these lesions can be a precursor of future strokes, 3D MDCT/CBCT images should evaluate meticulously not only extracranial but also intracranially, especially in OSA patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
