Advanced oral squamous cell carcinoma (SCC) is a possible risk factor for myiasis, a parasitic infestation of vital tissue of humans or other mammals by dipterous larvae (maggots). Oral myiasis is a rare entity, and is mostly associated with various medical and anatomical conditions, such as neglected mandibular fracture, lip incompetence, cerebral palsy, poor oral hygiene, suppurative lesions, and cancerous wounds. Larvae cause itching and irritation due to their crawling movements and can destroy vital tissues, inducing serious or even life-threating hemorrhage. The aim of the present article was to highlight the occurrence of oral myiasis in association with squamous cell carcinoma and also to highlight the treatment and preventive approaches for such cases. A literature search was performed using MEDLINE for articles published in English relating to the occurrence of oral myiasis in oral SCC. Our search revealed 6 reports on myiasis associated with oral SCC. The surgical debridement of infected tissue with the removal of maggots is the treatment of choice in most cases of oral myiasis.

This study was conducted to evaluate Yemeni dental practitioners knowledge and practices concerning fissure sealants.A modified questionnaire consisted of 25-items was distributed to 500 dentists working in Sanaa City. Descriptive statistics and Chi-square/Fishers exact tests were used for statistical analyses.The response rate was 74%. Most of the respondents were male (61.3%), general practitioners (84.2%), and had <5 years of clinical experience (48.3%). The respondents showed a reasonable level of knowledge about sealants, with the majority (88%) believed that there is strong scientific evidence about fissure sealants effectiveness and around 90% showed a good understanding of sealant placement instructions. On the other hand, respondents showed insufficient knowledge about sealants clinical practice.Although a high proportion of dental practitioners showed adequate knowledge about dental sealant, following guidelines and standardized procedures in clinical practice is lacking. These emphasize the need for regular continuing education courses for dental professional.

More than 50 % of oral cancer cases are diagnosed at advanced stages. Public knowledge about oral cancer can help in prevention and early detection of the disease. The aim of the present study was to assess the levels of awareness and knowledge about signs and risk factors of oral cancer among dental patients in Saudi Arabia. A self-administered questionnaire was used to collect information from 1410 randomly selected patients attending dental departments within public hospitals in Riyadh, Saudi Arabia. The collected data were analyzed using SPSS software. The significance level was set at P < 0.05. The study revealed that only 62.4 % were aware of oral cancer. Some 68.2 and 56.5 %, respectively, were able to correctly identify tobacco and alcohol as risk factors. More than two thirds of subjects had no knowledge about any signs of oral cancer. Participants with lower than university education were significantly less aware, and had much less knowledge, of the signs and risk factors of oral cancer. The knowledge regarding oral cancer among Saudi dental patients is alarmingly low. Interventions to improve public knowledge about oral cancer and attitudes towards early diagnosis and treatment are urgently indicated. © 2015 American Association for Cancer Education

Background: Oral cancer presents with high mortality rates, and the likelihood of survival is remarkably superior when detected early. Health care providers, particularly dentists, play a critical role in early detection of oral cancers and should be knowledgeable and skillful in oral cancer diagnosis. Purpose: The aim of the present study was to assess the current knowledge of future Yemeni dentists and their opinions on oral cancer. Materials and Methods: A pretested self-administered questionnaire was distributed to fourth and fifth year dental students. Questions relating to knowledge of oral cancer, risk factors, and opinions on oral cancer prevention and practices were posed. Results: The response rate was 80%. The vast majority of students identified smoking and smokeless tobacco as the major risk factors for oral cancer. Most of the students (92.6%) knew that squamous cell carcinoma is the most common form of oral cancer, and 85.3% were aware that tongue and floor of the mouth are the most likely sites. While the majority showed willingness to advise their patients on risk factors, only 40% felt adequately trained to provide such advice. More than 85% of students admitted that they need further information regarding oral cancer. As expected, students of the final year appeared slightly more knowledgeable regarding risk factors and clinical features of the disease. Conclusions: The findings of the present study suggest that here is a need to reinforce the undergraduate dental curriculum with regards to oral cancer education, particularly in its prevention and early detection.

Background: The aim of this study was to assess the level of awareness and knowledge about signs and risk factors of oral cancer in the general population in Saudi Arabia. Materials and Methods: A self-administered questionnaire was used to collect information from Saudi adults aged 15 years and older. A total of 679 persons participated in the survey. Descriptive statistics were calculated and chi-square tests, t-tests, and one-way analysis of variance (ANOVA) were used to examine differences between groups. The significance level was set at p<0.05. Results: Only 53.6% of the participants had heard of oral cancer. Smoking and alcohol consumption were identified as the major risk factors by 81.7% and 56.3% of the participants, respectively. Only 22.2% and 18.2%, respectively, were able to correctly identify red and white lesions as early signs of oral cancer. Participants with less than high school education were significantly less aware, and had much less knowledge, of the signs and risk factors of oral cancer (p<0.05). Conclusions: This survey demonstrates a general lack of awareness among the public about oral cancer and a lack of knowledge about its signs and risk factors. There is a clear need to inform and educate the public in matters relating to the known risk factors associated with oral cancer. A media campaign informing the public about oral cancer is clearly required.

The aim of this study was to evaluate knowledge, attitudes, and practices regarding infection control procedures among senior dental students.A questionnaire-based cross-sectional survey was conducted among 145 4(th)- and 5(th)-year dental students at the Faculty of Dentistry, Sanaa University, Yemen. The self-administered questionnaire was comprised of 20 open- and close-ended items regarding barrier techniques, vaccination status, infection control practices, and awareness. Data were analyzed with a Chi-square test. A P 0.05 was considered significant.The response rate was 72% (145 out of 204 potential respondents). Overall, 71.7% of the students had been vaccinated for hepatitis B and only 9.5% were tested for post-hepatitis B virus immunization serology. While the vast majority (96.6%) reported always wearing gloves for all dental procedures, the use of face masks and eyewear were reported by only 53.8% and 14.0% of students, respectively, with no significant difference between genders and year of study (P > 0.05). A significantly higher percentage of 5(th)-year students (58.9%) showed positive attitudes toward the treatment of patients with infectious diseases, as compared to only 31.0% of 4(th) year students (P < 0.01). A great number of students (62%) reported non-sterile occupational percutaneous and mucous injuries while treating their patients.These unsatisfactory findings highlight the necessity of continued infection control education in order to improve knowledge, attitudes, and practices regarding infection control among dental students at Sanaa University.
