Oral Cancer Knowledge, Attitudes and Practices among Primary Oral Health Care Dentists in Kuwait

Bridging the knowledge-Practice gap: Insights from a survey of Belgian dental professionals on diagnosis and supportive oral cancer treatment in comparison with international guidelines

OBJECTIVE

Early detection significantly improves the prognosis of oral cancer patients, contingent upon the knowledge of dental professionals. This study aimed to assess and compare the knowledge, practices and perceptions regarding oral cancer among dental professionals in Belgium.

MATERIALS AND METHODS

A cross-sectional survey was distributed via Qualtrics to general dentists, dental specialists, dental hygienists, and oral and maxillofacial surgeons. The self-administered questionnaire comprised three sections: demographics (4 questions), knowledge (9 questions) and clinical practices (19 questions) related to oral cancer detection and treatment. Descriptive statistics were employed for data analysis, with Chi-square tests assessing responses by specialization, gender, years of experience and number of oral cancer patients treated.

RESULTS

A total of 262 questionnaires were completed, with the majority of respondents being general dentists (61%) followed by dental specialists (25%), oral hygienists (8%) and oral and maxillofacial surgeons (6%). 70% of the respondents reported treating fewer than four oral cancer patients throughout their careers. 5 out of the 9 knowledge questions achieved over 50% correct responses, with an average correct answer rate of 54%. Oral and maxillofacial surgeons and dental professionals who have treated more than four oral cancer patients, demonstrated significantly higher scores on multiple knowledge questions. Responses to clinically oriented questions showed less diversity across professions, and generally aligning with guidelines from professional oncological societies.

CONCLUSION

This survey highlights the need for enhanced education on oral cancer among Belgian dental professionals. Knowledge levels were notably higher among more experienced respondents. The development and implementation of comprehensive guidelines tailored to dentists and oral hygienists for oral cancer prevention and patient care are warranted to optimize clinical practice standards.

Oral Cancer Awareness Among Princess Nourah bint Abdulrahman University Dental Students and Interns

BACKGROUND

Dentists have a very important role in the early diagnosis of oral cancer premalignancy. This aspect of dental practice requires an adequate level of knowledge.

OBJECTIVE

This study aimed to assess the level of knowledge of undergraduate dental students and dental interns about early diagnosis and risk factors of oral cancer.

METHODS

The present cross-sectional study was conducted at the Dental College, Princess Nourah bint Abdulrahman University, Saudi Arabia. Fourth-year and fifth-year students and dental interns were enrolled in the study. The participants were recruited using a convenient, non-probability sampling method. A total of 103 participants filled out a close-ended, online questionnaire. We used descriptive and analytical statistics to analyze the responses to the questionnaire.

RESULTS

The level of general knowledge was moderate (67%). More than half of the participants gave complete responses to questions related to early signs of oral cancer (67%), risk factors (54%), risk sites (75%), treatment plans for leukoplakia (66%), and unhealed ulcer management (58%). We found significant associations between the correct responses and the year of the study regarding early signs of oral cancer (p=0.0001), high malignant potential lesions (p=0.00001), and chronic unhealed ulcer management (p=0.015).  Conclusion: A more satisfactory level of awareness is needed among future dentists, to prevent missing patients undiagnosed with early oral cancerous lesions during routine screening. Consequently, upgrading theoretical curricula, clinical experience, and post-graduate participation in cancer prevention programs is highly recommended.

Knowledge, Opinions, and Practices of Oral Cancer Prevention among Palestinian Practicing Dentists: An Online Cross-Sectional Questionnaire

Oral-health professionals play a critical role in the early recognition and prevention of oral cancer; however, most patients are diagnosed in the advanced stages that demonstrate poor prognosis. Therefore, this study aimed to investigate the knowledge, opinions, and clinical practices of practicing dentists related to oral cancer prevention and oral mucosal screening in Palestine. This research used an online cross-sectional questionnaire design. Practicing dentists in Palestine completed the 44-item questionnaire encompassing the following four sections: (a) personal data (6 items); (b) oral cancer knowledge (21 items); (c) opinions and beliefs related to oral cancer (10 items); and (d) clinical practices related to oral cancer (7 items). The questionnaire was sent to all eligible participants (N = 650) between July and September of 2022. The response rate was 39.1% (N = 254). About 70.1% of the respondents had poor knowledge of oral cancer and its risk factors, and almost 84.3% had positive opinions related to oral cancer prevention and oral mucosal screening. Concerning the clinical practices, only 29.9% routinely examined their patients every time their patients visited. More experienced dentists showed significantly more positive opinions and better clinical practices related to oral cancer prevention and screening; however, they had significantly lower knowledge scores compared with the younger dentists (p < 0.05). Inadequate training was the most reported perceived boundary against routine oral cancer screening. Palestinian dentists appeared to have positive opinions related to oral cancer prevention and oral mucosal screening. However, the assessment of the knowledge and clinical practices revealed deficiencies in this regard.

Association between sociodemographic characteristics and level of knowledge about oral cancer among Mexican dental health professionals: a cross-sectional online survey

BACKGROUND

A good level of knowledge in dentists is crucial for an early diagnosis of oral cancer (OC). In Latin America there are a few studies of OC knowledge among dentist, those has been performed in Brazil, Colombia, and Chile, and their results showed low level of OC knowledge. On the other hand, there is no publication in which the level of knowledge of dentists in Mexico has been addressed. Therefore, this study aimed to assess knowledge of OC and to determine the association of the level of knowledge with sociodemographic characteristics among dentists in Mexico.

METHODS

A cross-sectional online survey was designed to obtain information via questionnaire. The questionnaire was developed in the Spanish language, and the content validity was determined. The study was conducted among Mexican dentists with a 23-item questionnaire that was designed to be anonymous. The sample size was calculated using the finite population formula. Based on the responses, the level of knowledge of OC was categorized as very low, low, regular, good, or excellent. Additionally, the association between sociodemographic characteristics and the level of knowledge about OC was evaluated.

RESULTS

This research was conducted on a sample of 387 dentists. Most of the respondents were general dentists and worked in urban zones. The majority of dentists lacked a specialty (76.7%). Additionally, most of the respondents were students (44.2%). The level of knowledge of the participants was between regular and good (77.8%). On the other hand, concerning self-evaluation, most of the participants considered their knowledge of OC to be regular (50.6%). In addition, there was no association between sociodemographic characteristics and knowledge about OC.

CONCLUSIONS

This research identified some weaknesses in most Mexican dentists' knowledge of OC.

Knowledge, attitudes, and practices of oral cancer prevention among dental students and interns: an online cross‑sectional questionnaire in Palestine

Background

Oral cancer is frequently characterized with an aggressive behavior and an unfavorable prognosis; however, it is generally associated with promising prognosis if detected early. Therefore, this study aimed to assess knowledge, practices, and attitudes toward oral cancer prevention among dental students and interns; and to investigate the factors that influence their practices of oral cancer screening or prevention.

Material and methods

A cross-sectional questionnaire-based survey was conducted between March and April of 2022 on the fourth- and fifth-year undergraduate dental students and interns in the College of Dentistry at Arab American University in Palestine. A 48-item questionnaire which has 4 sections: demographics, knowledge, practices, and attitudes toward oral cancer prevention and early detection was sent to all eligible participants (N = 570).

Results

The response rate was 68.7% (N = 351). About 66.8% of the respondents had poor knowledge about oral cancer and its risk factors, and 85.5% had a poor practice of oral cancer early detection and prevention; however, the majority of the respondents (81.1%) had shown favorable attitudes toward oral cancer prevention. Interns had significantly better knowledge and attitude scores compared to the undergraduate dental students (P < 0.05). Lack of training, time, confidence, and effectiveness were stated among the barriers to oral cancer screening.

Conclusions

Most of the participants surveyed in this study appeared to lack adequate knowledge and skills in oral cancer prevention and early detection; however, they seemed to have good motivation and a good attitude toward oral cancer prevention training.

Predictive Factors in the Appearance and Evolution of Squamous Cell Carcinomas of the Oral Cavity

Background: Oral squamous cell carcinoma (OSCC) registered an alarming fall in the average age of individuals diagnosed in the last decade. Objectives: The aim of our study is to assess the main risk factors for OSCC specific to Romania and to identify patients at risk for this pathology. The purpose is to implement in the future a screening and early diagnosis program for OSCC in our country. Materials and Methods: A ten-year case-control study was conducted on patients selected from “St. Spiridon” Hospital-Iaşi, Romania. The study contained 1780 individuals diagnosed with oral squamous cell carcinoma. Results: For the patients under 46 years old: APC = −2.8 percent (95% CI: −24.4 to −7.1; p = 0.0012), with the observed rate of 30.18 percent. The incidence increased in patients aged 46 to 49 years (APC = 9.6%; 95% CI: 6.7 to −10.4; p = 0.0081). For the age group 49 to 64 years old: APC = −2.4 percent (95% CI: −5.3 to −1.6, p = 0.1239). For the age group 64–74: APC = −4.6, (95% CI: 1.4 to 6.9, p = 0.0108). The incidence of incidents was lower in the age group 74–80 (p = 0.0025). For the age group 80–91: APC = 8.1 (95% CI: 6.4 to 14.2, p = 0.0024), with the incidence of cases: APC = 8.1 (95% CI: 6.4 to 14.2, p = 0.0024). Univariate analysis revealed a substantially higher risk of developing oral carcinoma in males (OR = 4.43; CI: 3.84 to 5.80). Age above 60, cigarette usage and alcohol abuse are significant risk factors for OSCC. Patients with lymph node dissemination, ulcero-vegetant form, stages II and IV, whose therapeutic approach consisted of radiotherapy and chemotherapy or radiotherapy only had a worse rate of survival at 24 months post-therapy. Conclusions: Our study highlights the increase in the incidence of OSCC in Romania during the research period, the decrease in the average age of diagnosed patients, as well as the degree to which the studied population is exposed to the main risk factors specific to this geographical area.

Knowledge, awareness, and attitude among dental students regarding oral cancer in Saudi Arabia

Background

Oral cancer awareness among junior and seniors' dental undergraduate students may have an impact on the early detection and prevention of oral cancer.

Aims and Objectives

To assess oral cancer awareness, knowledge and attitude among undergraduate dental students in government and private colleges in Saudi Arabia.

Material and Methods

A cross-sectional survey was undertaken to assess oral cancer knowledge, awareness and attitude among undergraduate dental students in government and private colleges in Saudi Arabia. All junior and senior students enrolled during the 2020- 2021 academic year, were eligible to participate (n=189).

Results

The study shows that dental Students at private and government colleges in Saudi Arabia are generally knowledgeable regarding Knowledge, awareness, attitude and management of oral cancer. There was no significant difference between knowledge, awareness, attitude, and management of oral cancer between students in either private and government colleges. Results shows that 99 (88.9%) of dental students in government colleges considered human papilloma virus as a risk factor, higher than dental students in private colleges 48 (73.3%). My results indicated that dental students considered (87%) tobacco, and alcohol (83.6%) as main risk to oral cancer, whereas, 100 (53%) identified limited consumption of fruit and vegetables and 124 (65.6%) considered old age as risk factor for oral cancer.

Conclusion

The variation in correct answers indicate to need to reinforce the undergraduate dental curriculum with regards to oral cancer education; particularly in its prevention and early detection. Revision of knowledge senior students in oral cancer is highly recommended.

Knowledge, attitudes, and practices of oral cancer prevention among students, interns, and faculty members at the college of dentistry of Jazan University

Background

Oral cancer awareness among current and future dental practitioners plays a substantial role in the early detection and prevention of oral cancer. Therefore, this study aimed to assess the knowledge, attitudes, and practices (KAP) of oral cancer prevention (OCP) among oral health practitioners in the College of Dentistry at Jazan University, Saudi Arabia, and to determine factors that facilitate, or limit practices related to oral cancer prevention.

Methods

A self-administered questionnaire survey was done among dental students (n = 274), interns (n = 81), and faculty members (n = 117) in the College of Dentistry at Jazan University between May 2019 to February 2020. The questionnaire was developed in English and modified from a previously validated and published questionnaire into Arabic. It covered every KAP of oral cancer prevention that was useful in accomplishing the study's objectives. Logistic regression analysis was utilized to determine the factors associated with the practice of oral cancer prevention in the past year.

Results

Only 29.7% reported having participated in any OCP activities in the past 12 months while about 42% and 53% of participants referred suspected oral cancer patients to the departments of maxillofacial surgery and oral medicine, respectively. Most of the participants had poor knowledge (71.9%), unfavourable attitudes towards OCP (83.6%) and poor levels of practice (62.9%). The study found that the attitude of the participants was significant in influencing their practices of OCP in the previous 12 months, after adjusting for all other factors.

Conclusion

It was concluded that the level of knowledge, attitudes, and practices of OCP among the sample population was poor. The survey findings suggest that oral health practitioners in Jazan are inexperienced in the methods to adopt for prevention and early detection of oral cancer, despite the high prevalence of oral cancer among province residents. Further research should investigate effective educational strategies and training for improving the participation of students, interns, and faculty members in oral cancer prevention activities.

Current Knowledge, Attitudes, and Practice among Health Care Providers in OSCC Awareness: Systematic Review and Meta-Analysis

OSCC remain a global health problem. Lack of awareness leads to inadequate watchfulness regarding early signs/symptoms despite the ease of visual oral inspection. What clinicians know and feel, and how they behave on OSCC is crucial to understand the feasibility and effectiveness of screening programs. The aim of this systematic review was to assess knowledge, attitudes, and practice (KAP) regarding OSCC among health care providers (HCPs). Therefore, a systematic review was conducted with SPIDER and PICO as major tools. A meta-analysis was structured through common items in two comparison groups of medical and dental practitioners. Descriptive statistics and a Mantel–Haenszel test were used to validate data. Sixty-six studies were selected for systematic review, eight of which are useful for meta-analysis. A statistically significant difference was recorded between dentists and medical practitioners for questions regarding: Alcohol (p < 0.001); Elderly (p < 0.012); Sun exposure (p < 0.0001); Erythroplakia (p < 0.019); Red patch (p < 0.010); White patch (p < 0.020); Tobacco consultation (p < 0.0001); Intraoral examination (p < 0.0001) and Up-to-date knowledge (p < 0.002). Overall, the incidence of OSCC screening is low. Most HCPs feel the need to increase KAP. Data confirmed gaps in KAP, highlighting the need for a more efficient pre- and post-graduation training, necessary to increase competence worldwide.

Knowledge of oral and oropharyngeal cancer by dental surgeons: an integrative review

OBJECTIVES

to identify the evidence available in the literature on the knowledge of dentists regarding risk factors and early diagnosis of oral and oropharyngeal cancer.

METHODS

it is an integrative review of the literature. Boolean descriptors and operators were searched in the PubMed and LILACS databases, using gray literature, in English, Spanish and Portuguese.

RESULTS

of the 79 PubMed and 152 LILACS articles, 24 were selected. Of these, eight showed good knowledge of dentists, while most showed low or little knowledge of risk factors and early diagnosis in dentists. All studies, however, highlight the need for continuing education to improve and maintain knowledge about risk factors and early diagnosis.

CONCLUSIONS

most dental surgeons have insufficient knowledge of oral/oropharyngeal cancer. Continued education is suggested, aiming at improving knowledge and early diagnosis.

Oral and oropharyngeal cancer: Knowledge, attitude and practices among medical and dental practitioners

Background

Oral and oropharyngeal cancer are significant health problems. They are both life‐threatening conditions usually diagnosed at an advanced stage causing survival rates to decline.

Aim

To assess and compare practices, knowledge and attitude regarding oral and oropharyngeal cancer between dental and medical practitioners.

Methods

A cross‐sectional study was conducted to assess knowledge, attitude and practices of oral and oropharyngeal cancer among dental and medical practitioners at King Abdulaziz Medical City, Riyadh, Saudi Arabia. 360 participants were included in the study using a convenient sampling technique. Participants were approached in their clinics and printed self‐administered questionnaire were handed over to them after signing a written consent form. Frequency distribution and Chi‐Square test were used for the statistical analysis and the level of significance was set at P value of .05 or less.

Results

A total of 174 participants responded. Assessment of oral and oropharyngeal cancer knowledge between dental practitioners and medical practitioners showed comparable results. Regarding practices, a significant difference was seen between medical practitioners and dental practitioners in determining the duration of intra‐oral ulcer to consider urgent referral (P = .006) and in number of referrals made in relation to suspicious oral lesions (P = .002). Moreover, a significant difference (P = .006) was seen between medical practitioners and dental practitioners in determining the duration of intra‐oral ulcer to consider urgent referral.

Conclusion

Medical and dental practitioners showed areas of differences in practice, attitude and knowledge of oral and oropharyngeal cancer that when addressed would lead to improved survival rates.

Knowledge and Practice Regarding Oral Cancer: A Study Among Dentists in Jakarta, Indonesia

Objective

To assess Indonesian dentists' knowledge of risk factors and diagnostic procedures related to oral cancer (OC) and to determine the factors that influenced their level of knowledge.

Methods

A modified version of a questionnaire that had been used to assess dentists’ knowledge regarding OC in Canada was used. A total of 816 dentists were invited to participate in the study.

Results

The total response rate was 49.2%; however, the number of dentists from 5 regions in Jakarta were equally represented. Use of tobacco or alcohol and history of previous OC were the top 3 risk factors that were answered correctly by dentists, but there was a high proportion of dentists who considered some without any evidence as risk factors. Almost half of the dentists did not know the early signs of OC and that erythroplakia and leukoplakia were associated with increased risks of developing OC. Only about 27% of dentists had a high level of knowledge of risk factors and fewer dentists demonstrated a good knowledge of diagnostic procedures. Dentists’ age group, year of graduation, and experience of continuing education significantly influenced the level of knowledge of diagnostic procedures (P < .05).

Conclusion

Dentists in Jakarta had a considerable level of knowledge of major risk factors of OC, although some gaps in their knowledge, especially in diagnostic procedures, were present. Increasing these competencies may aid in the prevention and early detection of OC.

Early detection of oral cancer and potentially malignant disorders: Experiences, practices, and beliefs of prosthodontists practicing in Saudi Arabia

STATEMENT OF PROBLEM

Data on the oral cancer screening skills and beliefs of prosthodontists practicing in Saudi Arabia are lacking.

PURPOSE

The purpose of this survey was to assess the beliefs, experiences, and practices of prosthodontists practicing in Saudi Arabia regarding the early detection of oral cancer and potentially malignant disorders.

MATERIAL AND METHODS

A cross-sectional, questionnaire-based survey was conducted on prosthodontists practicing in Saudi Arabia. A 26-item questionnaire was sent to all eligible prosthodontists (N=250). The collected data were analyzed with a statistical software program.

RESULTS

The response rate was 57.2% (N=143). The majority of participants (79%) reported that they routinely examined all new patients for mucosal pathologies. However, only 58% reported that they examine their patients at recall visits, and only 61.5% stated that they provide tobacco use or smoking cessation advice. With regard to the respondents' experiences with suspicious mucosal lesions, the majority said that they had detected a suspicious lesion (79.7%) and had referred affected patients (83.2%) during their career. Most prosthodontists (65%) believed that they were able to detect oral cancer on their own, and 40% believed that they could influence their patients to stop smoking. A lack of training, confidence, time, and financial incentives were reported as barriers to oral cancer screening.

CONCLUSIONS

Most of the prosthodontists surveyed in this study appeared motivated to perform routine oral mucosal screening. However, more efforts are needed to help improve the attitudes, confidence, and skills of prosthodontists when it comes to identifying and referring suspicious oral mucosal lesions.
