INTRODUCTION
Oral cancer poses a significant global health challenge, with over 300,000 new cases diagnosed annually worldwide.[1] Its insidious nature often leads to late-stage detection, resulting in poor prognosis and reduced survival rates.[2] Early identification of oral cancer is pivotal for successful treatment and improved patient outcomes.[3] Dental professionals, including dentists and dental hygienists, are uniquely positioned to contribute to the early detection of oral cancer during routine dental check-ups.[4] However, the extent to which dental professionals conduct oral cancer screenings and the methods they employ during these examinations remain subjects of interest and concern within the healthcare community. Oral cancer primarily encompasses malignancies of the oral cavity, including the lips, tongue, floor of the mouth, palate, and gums. Its symptoms often manifest as persistent ulcers, red or white patches, lumps, or chronic pain, which can be visible or palpable within the oral cavity. These early signs and symptoms may be readily discerned through visual inspection and manual palpation during a dental examination. Additionally, adjunctive screening tools, such as toluidine blue staining or VELscope, have been developed to aid in identifying subtle or hidden lesions. The importance of oral cancer screenings conducted by dental professionals cannot be overstated. Routine dental check-ups serve as opportunities for timely detection of oral cancer, potentially leading to early intervention and improved patient survival rates.[3,4,5] Nevertheless, a comprehensive understanding of how frequently dental professionals perform these screenings and the methods they employ is vital for optimizing oral cancer detection and, ultimately, patient care.[6] The aim of this study is to investigate how frequently dental professionals conduct oral cancer screenings during routine dental check-ups and the methods they employ.
MATERIALS AND METHODS
Study design
This investigation employed a cross-sectional survey design to examine the frequency and methods of oral cancer screenings conducted by dental professionals during routine dental check-ups. The study aimed to gather data from a sample of 500 dental professionals, including dentists and dental hygienists, representing various geographic locations and years of experience.
Sample size and recruitment
The study’s target sample size was 500 dental professionals. Participants were recruited through a convenience sampling method, with an emphasis on ensuring diversity in terms of geographic location, years of experience, and practice settings (e.g. private practices, dental clinics, hospitals). Recruitment efforts included contacting dental associations, distributing surveys through professional networks, and utilizing online platforms dedicated to dental professionals.
Survey instrument
A structured survey questionnaire was developed to collect data on the frequency and methods employed by dental professionals for oral cancer screenings.
Data collection
The survey questionnaire was distributed electronically to the selected participants using online survey platforms and email communication. Participants were provided with a link to the survey, which they could complete at their convenience.
Data analysis
Descriptive statistical analyses were conducted to analyze the collected data. Frequencies and percentages were calculated to summarize the responses regarding the frequency and methods of oral cancer screenings. Cross-tabulations and Chi-square tests were employed to explore associations between variables, such as years of experience, geographic location, and screening frequency. Statistical significance was set at P < 0.05.
RESULTS
Among the 500 dental professionals surveyed, the study found that 85% reported conducting oral cancer screenings during routine dental check-ups. These screenings were performed at varying frequencies, with the majority of respondents indicating annual screenings (48%), followed by screenings at every dental visit (33%). A smaller proportion of participants reported conducting screenings less frequently (19%) [Table 1].
Table 1.
Frequency of oral cancer screenings during routine dental check-ups
| Frequency of screenings | Percentage of respondents |
|---|---|
| Every dental visit | 33% |
| Annually | 48% |
| Less frequently | 19% |
| Total | 100% |
Visual inspection and palpation were identified as the primary methods used by dental professionals for oral cancer screenings. Visual inspection, conducted during every routine dental check-up, was reported by 97% of respondents. Palpation, a tactile examination of the oral cavity, was routinely performed by 83% of dental professionals. Adjunctive screening tools, such as toluidine blue staining or VELscope, were less commonly utilized, with only 45% of respondents incorporating these tools into their oral cancer screenings [Table 2].

| Screening method | Percentage of respondents |
|---|---|
| Visual Inspection | 97% |
| Palpation | 83% |
| Adjunctive Screening Tools | 45% |
DISCUSSION
The discussion section delves into the implications and interpretations of the study’s findings regarding the frequency and methods employed by dental professionals during oral cancer screenings in routine dental check-ups. It also explores the significance of these findings, potential factors influencing screening practices, and recommendations for improving oral cancer screening protocols. The study revealed that 85% of dental professionals surveyed conduct oral cancer screenings during routine dental check-ups. This finding is encouraging as it underscores the commitment of dental professionals to the early detection of oral cancer, aligning with the crucial role they play in public health. The majority of respondents (48%) reported performing these screenings annually, suggesting a general adherence to a regular screening schedule. Furthermore, 33% of dental professionals conduct oral cancer screenings at every dental visit, ensuring frequent opportunities for early detection. The study also identified a subgroup (19%) of dental professionals who perform oral cancer screenings less frequently. Several factors may contribute to this discrepancy, including variations in practice settings, patient populations served, and the availability of time and resources. It is essential to recognize that the appropriate frequency of screenings may vary depending on the individual patient’s risk factors, as well as local and regional oral cancer prevalence rates.
Visual inspection and palpation emerged as the primary methods used by dental professionals for oral cancer screenings, with 97% and 83% of respondents, respectively, routinely employing these techniques. Visual inspection, based on its accessibility and non-invasive nature, remains a cornerstone of oral cancer screenings.[7] Palpation complements visual inspection by allowing for the assessment of palpable lesions and irregularities within the oral cavity. However, the relatively lower utilization of adjunctive screening tools (45%) raises questions about the comprehensive nature of current screening protocols. These tools, such as toluidine blue staining and VELscope, have the potential to enhance the sensitivity and specificity of screenings by detecting subtle or hidden lesions that may not be visible to the naked eye.[8] The limited adoption of adjunctive tools suggests an area for improvement in oral cancer screening practices.
CONCLUSION
In conclusion, this study provides valuable insights into the current state of oral cancer screening practices among dental professionals. While the majority conduct screenings regularly, there is room for improvement in the adoption of adjunctive screening tools and the standardization of screening protocols. By addressing these areas, dental professionals can contribute more effectively to early oral cancer detection and ultimately improve patient outcomes in the field of dentistry.
