Awareness and Knowledge of Oral Cancer among Dental Patients in Aseer Region, Saudi Arabia: A Questionnaire-Based Survey

Awareness and Knowledge of Oral Cancer among Dental Patients in Aseer Region, Saudi Arabia: A Questionnaire-Based Survey

Oral Cancer Screening among Smokers and Nonsmokers.

Aims and Objectives:The aim of visual systematic screening is early identification of oral cancer (OC) precursor lesion. OC mortality improves when cancer is identified at early stages. This is important in patients whose lifestyle choices render them at higher risk of developing OC. This study described the prevalence of OC screening among smokers and nonsmokers in Kuwait and ascertained demographic predictors.Materials and Methods:This cross-sectional study utilized a self-administered online survey in English and Arabic through Survey Monkey® and disseminated using the social networking app “WhatsApp.” The survey included 21 questions on demographics, smoking status, and knowledge of OC. Screening questions were adopted from the Maryland Cancer Screening and Risk Behavior Survey. Data were analyzed using the computer software “Statistical Package for Social Sciences, SPSS version 24.0” (IBM Corp, Armonk, NY, USA).Results:The study included 404 Kuwaiti respondents, 311 (77%) nonsmokers and 93 (23%) smokers. Prevalence of OC screening was 7.2, 7.7% among nonsmokers and 5.4% in smokers. Only 36.6% were aware of OC, with more nonsmokers (38.9%) than smokers (29%). Logistic regression revealed twice more males likely to go for screening than females and with the likelihood of those being in the age group of 25–44 years four times more (P < 0.012) than other age groups.Conclusion:There was low prevalence of screening and poor awareness of OC among sampled. Increased efforts are needed by health professionals to spread awareness and improve knowledge on OC and demand the inclusion of screening during their routine and opportunistic oral examinations.

Oral Cancer Knowledge and Awareness in Patients Visiting Kantipur Dental College.

Lack of knowledge and awareness about oral cancer, its risk factors and negligence of the early warning signs play crucial role in raising the incidence of the disease. The present study was carried out to evaluate the awareness of oral cancer among patients visiting Kantipur Dental College, Kathmandu, Nepal. The cross-sectional study was done in 471 patients from 15-85 years. Self administered questionnaire was prepared which comprised of knowledge of oral cancer, source of information, its early signs and symptoms along with the awareness of its risk factors. Most of the participants (41.80%) had not heard of oral cancer. 31.60% recognized tobacco smoking and tobacco chewing as the chief risk factor with 15.50% and 10.80% of participants who identified white patch and red patch as early sign of oral cancer respectively. Pearson's chi square test was used which showed statistically significant association of total mean knowledge score and awareness score with age, education level and occupation (p<0.05). This study done in dental patients showed lack of knowledge and awareness in general public about oral cancer. There seem to be a need for more planned awareness programs through newspapers, radio, television and health campaigns regarding the association of habits in the development of oral cancer and benefits of detecting oral cancer at early stage for better prognosis.

Oral cancer screening practices of oral health professionals in Australia

BackgroundTo evaluate oral cancer-related screening practices of Oral Health Professionals (OHPs - dentists, dental hygienists, dental therapists, and oral health therapists) practising in Victoria, Australia.MethodsA 36-item survey was distributed to 3343 OHPs. Items included socio-demographic and work-related characteristics; self-assessed knowledge of oral cancer; perceived level of confidence in discussing oral health behaviors with patients; oral cancer screening practices; and self-evaluated need for additional training on screening procedures for oral cancer.ResultsA total of 380 OHPs responded this survey, achieving an overall response rate of 9.4%. Forty-five were excluded from further analysis. Of these 335 OHP, 72% were dentists; (n = 241); either GDP or Dental Specialists; 13.7% (n = 46) were dental hygienists; 12.2% (n = 41) were oral health therapists, and the remaining 2.1% (n = 7) were dental therapists. While the majority (95.2%) agreed that oral cancer screening should be routinely performed, in actual practice around half (51.4%) screened all their patients. Another 12.8% “Very rarely” conducted screening examinations. The probability of routinely conducting an oral cancer screening was explored utilising Logistic Regression Analysis. Four variables remained statistically significant (p < 0.0001). Results indicate that the likelihood of conducting an oral cancer screening rose with increasing levels of OHPs’ confidence in oral cancer-related knowledge (OR = 1.35; 95% CI: 1.09–1.67) and with higher levels of confidence in discussing oral hygiene practices with patients (OR = 1.25; 95% CI: 1.03–1.52). Results also showed that dental specialists were less likely to perform oral cancer screening examinations compared with other OHPs (OR = 0.18; 95% CI: 0.07–0.52) and the likelihood of performing an oral cancer screening decreased when the “patient complained of a problem” (OR = 0.21; 95% CI: 0.10–0.44).ConclusionOnly half the study sample performed oral cancer screening examinations for all of their patients. This study provides evidence of the need for further oral cancer-related education and screening training for OHPs, which is vital to enhance oral cancer prevention and early detection.

Oral Cancer Knowledge, Attitudes, and Practices among Dentists in Khartoum State, Sudan.

The dental professions hold an important responsibility in the control of oral cancer and the early diagnosis highly depends on their knowledge. The present study was developed to assess the knowledge, attitude, and practice of dentists in Khartoum State regarding oral cancer prevention and early detection. An administered questionnaire was structured and sent to all licensed 130 dentists working in public dental clinics in Khartoum State. Responses to the questionnaire were analyzed using descriptive and analytical statistics. Although the majority of the dentists were knowledgeable about the major risk factors of oral cancer, more than half of the dentists reported they do not carry out any special examination to detect oral cancer in age 40 and above in asymptomatic patients. Dentists indicated their lack of training as the main barrier for conducting a comprehensive oral cancer examination. Interestingly, the vast majority of the dentists express their interest to have further oral cancer educational and training sessions. The findings of the present study suggested strongly that educational and training interventions are necessary to enhance preventive measures which may lead to reduce mortality and morbidity from oral cancer.

Population Survey of Knowledge about Oral Cancer and Related Factors in the Capital of Iran.

Knowledge about oral cancer risk factors and signs is thought to improve prevention and early diagnosis, and in turn, increases survival. In this population-based survey, knowledge about oral cancer was assessed in Iran. A total of 1800 self-administered questionnaires (collecting sociodemographic data and questions regarding oral cancer risk factors and signs) were distributed through random sampling. Final scores ranged between 0 and 15 for the risk factors and 0-11 for the signs. Scores below the median indicated a low level of knowledge, scores representing the third quartile of correct answers indicated a moderate level of knowledge, and scores representing the upper quartile indicated a high level of knowledge. Statistical tests were used for analysis of knowledge level in different sociodemographic categories. A total of 1312 participants completed the questionnaires. The average of knowledge scores for risk factors was 5.3±3.0 and for signs was 4.5±2.9. Overall, 75 and 56% respectively were able to identify major risk factors (smoking and alcohol); 23.5% could not define any related signs and symptoms. Dividing scores into quartiles indicated that three out of four people had "low" knowledge about risk factors and 58% had "low" knowledge about signs and symptoms. Females and highly educated people had more knowledge of oral cancer. Significant difference was found between job and level of knowledge (P=0.001). This survey revealed that public knowledge of oral cancer was not satisfactory in Iran. Efforts should be done to inform and educate people with risk factors, initial clinical presentation, and symptoms, in order to improve prevention and promote early diagnosis.

KNOWLEDGE ABOUT ORAL CANCER AND THE ATTITUDES IN FRONT OF ITS ETIOLOGY AND PREVENTION, IN A GROUP OF HORTICULTURISTS

Oral cancer is a chronic disease of multifactorial origin, with high rates of incidence worldwide. However, the prevention and early diagnosis are the best ways to increase survival rate of their carriers. Thus, because of the relevance, the present work which the goal was to evaluate the knowledge of oral cancer and the attitudes adopted in face of the risk factors and preventive measures in 111 horticulturists, all volunteers, which were submitted to interviews.

Prevention of HPV-Related Oral Cancer by Dentists: Assessing the Opinion of Dutch Dental Students

The aim of this study is to assess dental students’ opinions of the dentists’ role in primary prevention of human papillomavirus (HPV)-related oral cancer using a cross-sectional web-based survey. A questionnaire, containing questions about knowledge of HPV and oral cancer, confidence in head and neck examination and role of the dentist in preventing HPV-related oral cancer, was sent to all students of the Academic Centre of Dentistry Amsterdam (n = 912). One hundred and twenty-six (n = 126) students completed the questionnaire. Significantly, more master students (75%) than bachelor students (54.3%) were aware that HPV is a causative factor for oral cancer. Master students had more knowledge of HPV than bachelor students, but knowledge about HPV vaccination was irrespective of the study phase. The majority of dental students agreed that it is important to discuss HPV vaccination with patients. Eighty-nine percent of the students think that more education about symptoms of oral cancer will increase screening for oral cancer. Development of a protocol for screening in dental practices was considered even more important. According to dental students, dentists should discuss HPV as a risk factor for oral cancer with patients. Future dentists are willing to be involved in both primary and secondary prevention of HPV-related oral cancer. Therefore, screening for oral cancer and education about HPV vaccination should be integral elements of the dental curriculum.

Characteristics and predictors of oral cancer knowledge in a predominantly African American community.

PurposeTo characterize smoking and alcohol use, and to describe predictors of oral cancer knowledge among a predominantly African-American population.MethodsA cross-sectional study was conducted between September, 2013 among drag racers and fans in East St. Louis. Oral cancer knowledge was derived from combining questionnaire items to form knowledge score. Covariates examined included age, sex, race, marital status, education status, income level, insurance status, tobacco and alcohol use. Adjusted linear regression analysis measured predictors of oral cancer knowledge.ResultsThree hundred and four participants completed questionnaire; 72.7% were African Americans. Smoking rate was 26.7%, alcohol use was 58.3%, and mean knowledge score was 4.60 ± 2.52 out of 17. In final adjusted regression model, oral cancer knowledge was associated with race and education status. Compared with Caucasians, African Americans were 29% less likely to have high oral cancer knowledge (β = -0.71; 95% CI: -1.35, -0.07); and participants with a high school diploma or less were 124% less likely to have high oral cancer knowledge compared with college graduates (β = -1.24; 95% CI: -2.44, -0.41).ConclusionsThere was lower oral cancer knowledge among African Americans and those with low education. The prevalence of smoking was also very high. Understanding predictors of oral cancer knowledge is important in future design of educational interventions specifically targeted towards high-risk group for oral cancer.

Validation of a Persian Short-Form Version of a Standardised Questionnaire Assessing Oral Cancer Knowledge, Practice and Attitudes Among Dentists.

Oral cancer is a global health problem; however, many dentists lack the necessary skills, knowledge and capacity to diagnose oral cancers early. This study aimed to examine the validity and reliability of a Persian short-form version of a standardised questionnaire to assess dentists' knowledge, practice and attitudes towards oral cancer. This cross-sectional analytical study was carried out in May 2015 in Tehran, Iran. An original 39-item English-language questionnaire developed by Yellowitz et al. was translated into Persian using forward and backward translation methods. A total of 15 dental professionals were asked to assess the questionnaire for content validity. Based on their feedback, a 20-item short-form version was prepared, including six demographic, six knowledge, four attitude and four practice items. The translated short-form questionnaire was subsequently distributed to 973 general dental practitioners attending a dental conference in Tehran. Internal consistency and reliability were assessed with Cronbach's alpha coefficient and item-total correlation calculations. A total of 13 professionals and 313 general dentists participated in the study (response rates: 86.7% and 32.2%, respectively). After the elimination of six items (two knowledge, two attitude and two practice items), the validity and reliability of the questionnaire was confirmed. The final Persian 14-item version of the questionnaire had acceptable validity and internal consistency. These results indicate that researchers can use this translated short-form version to evaluate oral cancer knowledge, attitudes and practices among Persian-speaking dentists; this will allow for a comparison of data between different populations.

Awareness and Knowledge of Oral Cancer among Siamese Ethnic Group in Tumpat, Kelantan.

Oral cancer is a life-threatening disease. Lack of public awareness is a potent barrier for the early detection of oral cancer, especially for high-risk populations. This study aimed to determine the awareness and knowledge of the signs, symptoms and risk factors of oral cancer among a Siamese ethnic group in Tumpat, Kelantan. A cross-sectional study was conducted, using a guided questionnaire on sociodemography, habits, awareness and knowledge of the signs, symptoms and risk factors of oral cancer. Individuals under 18 years old and who had been diagnosed with oral cancer were excluded from this study. A total of 195 respondents participated, 61.5% were female and the mean age was 46 (1.64). About 41% of the respondents had received secondary education and 35.4% were illiterate. Most respondents were self-employed (21.5%), followed by farmers (19.5%) and housewives (20%). The majority of them had a monthly income that fell below the poverty level of RM 830 (76.9%). Among the respondents, 22.6% had the habit of smoking, 25.6% consumed alcohol, 8.2% were betel quid chewers and 2.6% chewed tobacco. Out of 195 respondents, only 6.7% were aware of oral cancer. About 16.9% of the respondents correctly answered all of the questions regarding the signs and symptoms of oral cancer and only 4.1% knew the risk factors of oral cancer. The awareness and knowledge of oral cancer in this targeted population were unsatisfactory. Future effective health promotion programs and education should be emphasised.

Knowledge and Health Belief Attitudes of Oral Cancer and Its Screening Among At-Risk Southern Thai Muslims.

Oral cancer is one of the leading cancers in Thailand; southern Thai Muslims seem to have a longer delay in attending treatment for oral cancer than Buddhists in the same area. Visual screenings of high-risk populations have been suggested to be an effective prevention method. This study assessed oral cancer knowledge and belief attitudes influencing oral cancer screening in Thai Muslim high-risk groups. Twelve semi-structured in-depth interviews and the focus group discussion were conducted based on the health belief model. Stratified purposeful sampling was used to recruit the participants. Inclusion criteria were those who practiced the risk habits for oral cancer and were 40years of age or older, smokers (20+ cigarettes per day for at least 20years) and/or betel quid chewers (10+ times per day for at least 10years). Participants lacked knowledge about oral cancer in terms of signs and symptoms and predisposing factors. This influenced misleading belief attitudes concerning susceptibility of oral cancer, barriers, and their self-efficacy to have oral cancer screening examinations. Betel quid chewing was not regarded as a risk habit but as having a protective role against the disease. Perceived susceptibility was also seen by some to be dependent upon Allah's will. Traditional medication was mentioned as a preferred alternative to modern treatment. The latter was believed by some to be the cause of death for cancer patients. Interventions to promote oral cancer knowledge and right belief attitudes for oral cancer screening are clearly indicated.

Sociodemographic Factors Associated With Knowledge and Risk Perception of Human Papillomavirus and Human Papillomavirus–Associated Oropharyngeal Squamous Cell Carcinoma Among a Predominantly Black Population

The incidence of human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is increasing in the United States and may be underestimated among black individuals. Characterizing the current knowledge level among black individuals is critical to developing interventions to increase awareness. To describe the sociodemographic correlates of knowledge and risk perception of HPV and HPV-associated OPSCC among a predominantly black population. A cross-sectional survey was conducted at a drag racing event on September 12 and 13, 2015, in Madison, Illinois. The setting was a community-based oral head and neck cancer screening and education initiative. Participants were 301 drag race attendees 18 years or older who were conveniently sampled from attendees at an annual drag racing event predominantly patronized by black individuals. The primary outcome was knowledge and risk perception of HPV and HPV-associated OPSCC. An electronic-based questionnaire elicited sociodemographic information and contained oral cancer knowledge and risk perception items, which were combined to form knowledge and risk perception scores. Multivariable linear regression analysis assessed estimates of knowledge and risk perception of HPV and HPV-associated OPSCC. Of the 301 participants (111 female and 190 male) completing the questionnaire, 194 (64.5%) were black. Overall, respondents ranged in age from 18 to 78 years, with a mean (SD) age of 48.0 (13.0) years. The mean (SD) knowledge score was 5.7 (4.6) of 15, and the mean (SD) risk perception score was 2.2 (1.4) of 6. Using multivariable linear regression, we found that, for every 1-year increase in age, knowledge of HPV-associated OPSCC decreased by 5.0% and was worse in men (β = -1.26; 95% CI, -2.33 to -0.18), black vs white individuals (β = -1.29; 95% CI, -2.35 to -0.23), and those with a high school diploma or less vs college graduates (β = -3.23; 95% CI, -4.67 to -1.80). Black individuals also had lower perceived risk of developing HPV-associated OPSCC (β = -0.36; 95% CI, -0.69 to -0.02) compared with white individuals, and participants with a high school diploma or less had lower perceived risk of developing HPV-associated OPSCC compared with those with a college degree or higher (β = -0.59; 95% CI, -1.04 to -0.14). Age and sex were independent correlates of knowledge of HPV-associated OPSCC, while race and education level were correlates of both knowledge and risk perception of HPV-associated OPSCC. These findings should inform future interventions targeted at increasing knowledge of HPV-associated OPSCC in black communities.

Oral Cancer: Prevention and Early Detection, Dentists’ Opinions and Practices (Mashhad-Iran)

Background: Early detection is known to be the most effective way to promote survival and reduce mortality in cases of oral cancer. Objectives: This study is intended to survey dental practitioners across the city of Mashhad, in northeast Iran, in terms of their self-assessments and performance with regard to the early detection and/or prevention of oral cancers Patients and Methods: This descriptive, cross-sectional study involved 134 general dentists practicing in Mashhad between 2011 and 2012. Dentists' self-assessments, in terms of their knowledge, skill, competence, and performance when it comes to the primary and secondary prevention of oral cancers were assessed using a questionnaire. Statistical analysis was completed using SPSS (11.5). Results: 89.9 of dentists managed to support their patients in their efforts to stop smoking, though only 39 believed in their own capacity to assist with tobacco use cessation. Dentists reported that 35.4 of their patients aged 40+ had undergone screening for oral cancer during their first visit, whereas 11.6 received regular check-up on a periodic basis. Those prone to cancer constituted a larger percentage, at 76.6. More than half of the participants (59.3) believed that they had acquired the essential skills for oral cancer screening. This rate was reported to be 77.6 for lymph node palpation. Almost half of all dentists claimed that their knowledge of oral cancer was up to date. Conclusions: There is need for further training with regard to the early detection and prevention of oral cancers. © 2016, Zahedan University of Medical Sciences.

Public Knowledge of Oral Cancer and Modelling of Demographic Background Factors Affecting this Knowledge in Khartoum State, Sudan.

Knowledge of oral cancer affects early detection and diagnosis of this disease. This study aimed to assess the current level of public knowledge of oral cancer in Khartoum State, Sudan, and examine how demographic background factors affect this knowledge. This cross-sectional study involved 501 participants recruited by systematic random sampling from the outpatient records of three major hospitals in Khartoum State between November 2012 and February 2013. A pretested structured questionnaire was designed to measure knowledge levels. A logistic regression model was utilised with demographic background variables as independent variables and knowledge of oral cancer as the dependent variable. A path analysis was conducted to build a structural model. Of the 501 participants, 42.5% had no knowledge of oral cancer, while 5.4%, 39.9% and 12.2% had low, moderate and high knowledge levels, respectively. Logistic regression modelling showed that age, place of residence and education levels were significantly associated with knowledge levels (P = 0.009, 0.017 and <0.001, respectively). According to the structural model, age and place of residence had a prominent direct effect on knowledge, while age and residence also had a prominent indirect effect mediated through education levels. Education levels had the most prominent positive effect on knowledge of oral cancer among outpatients at major hospitals in Khartoum State. Moreover, education levels were found to mediate the effect of other background variables.

Student knowledge and awareness of oral cancer (study at Senior High School 2 Baubau, Southeast of Sulawesi)

Oral cancer is a malignancy which came from oral mucosal epithelial and other oral’s part including from saliva glands (majority the minor one) inside the mouth. Oral cancer has a quick spread. A half of oral cancer diagnosed at a late stage with a high level of death. Only half of this malignancy sufferer survive more than five years. However, the survival prognosis will increase 80-90% if the cancer could diagnose in early stage. The objective of this study is to measure qualitatively oral cancer knowledge and awareness among the students at SMAN 2 Baubau. This study is descriptive study by cross-section approach. Oral cancer knowledge and awareness among the students in SMAN 2 Baubau is in a low stage. Students hardly hear the information about the signs of oral cancer and have no idea what must they do if they find someone presented with one of the oral cancer signs. The reason behind unknown action lack of information and socialization about oral cancer.

Abstract B70: Characteristics, risk perception, and predictors of oral cancer knowledge among drag racers and their fans

Abstract Objective: Interventions for oral head and neck cancer prevention and early detection can be more effective if the higher risk individuals are targeted. The aim of this study was to characterize smoking and alcohol use, and describe predictors of oral cancer knowledge and risk perception among a predominantly African-American population. Methods: A cross-sectional study was conducted between September 13-14, 2013 among drag racers and fans in East St. Louis. Items were combined to form knowledge and risk perception scales, and outcome of interest was oral cancer knowledge level. Independent t-tests and one-way ANOVA assessed bivariate associations between variables. Logistic regression analysis measured predictors of oral cancer knowledge. Results: Three hundred and four participants completed questionnaire; 72.9% African Americans. Smoking rate was 26.7%; mean knowledge score 4.60 ± 2.52; and only 6.6% scored ≥ 9 out of 17 knowledge questions. Crude measures showed an association (p &amp;lt; .05) between oral cancer knowledge and sociodemographic variables (age, race, sex, educational status, marital status). In final adjusted regression model, only race and educational status remained predictors of oral cancer knowledge. Compared to other races, African Americans were three times more likely to have low oral cancer knowledge (95% CI = 1.47 – 6.49) and those with a high school diploma or less were five times more likely to have low oral cancer knowledge compared to college graduates (95% CI = 1.78 – 13.89). Conclusion and Relevance: There is a high smoking rate among drag racers and fans, but oral cancer knowledge is very low, especially among African Americans and those with limited education. Understanding predictors of oral cancer knowledge is important in future design of educational interventions specifically targeted towards this high-risk group.
