Human Papilloma Virus Vaccination and Oropharyngeal Cancer: Knowledge, Perception and Attitude among Italian Pediatric Dentists

Knowledge, attitude and perception of Italian dental students toward HPV-related oropharyngeal cancer and vaccination: a cross-sectional study

BACKGROUND

Human papillomavirus (HPV) infection is a leading cause of oropharyngeal squamous cell cancer (OPSCC). This study aimed to carry out a Knowledge, Attitude and Perception survey on HPV infection, HPV+ OPSCC, and HPV vaccination among Italian dental students.

METHODS

Through an online self-administered questionnaire consisting of 82 questions, data on dental students' sociodemographic characteristics, knowledge, attitudes and perceptions concerning HPV+ OPSCC, infection and vaccination were acquired. A statistical analysis, based on their year of attendance (early career, from 1st to 3rd year vs. late career, from 4th to 6th year) was also conducted.

RESULTS

A total of 412 dental students completed the questionnaire. Knowledge of HPV+ OPSCC was reported by 61% of early-career students and 73% of late-career students, with high awareness of the HPV-OPSCC correlation in both groups (85% vs. 89%, respectively). The percentage of correct responses regarding HPV infection knowledge was 61% for early-career and 73% for late-career students, while vaccine knowledge was 70% and 78%, respectively. Over 90% of students acknowledged the dentist's role in educating patients about HPV and OPSCC, and attitudes toward discussing HPV and vaccination were positive. However, only about half would recommend the vaccine to either gender. Statistically significant differences were found between early- and late-career groups across all knowledge sections (p < 0.001), while no significant differences emerged for perception (p = 0.076) or attitude (p = 0.147).

CONCLUSIONS

The study reveals encouraging results but highlights significant gaps in dental students' knowledge, perceptions, and attitudes toward HPV+ OPSCC, infection, and vaccination. Addressing these gaps through targeted education and training in dental curricula could improve HPV prevention awareness and patient education, ultimately enhancing public health outcomes.

Investigating women's awareness and perceptions on human papillomavirus infection and oropharyngeal cancer in Italy

Introduction

This study explored knowledge, attitudes and behaviors toward human papillomavirus (HPV) infection and oropharyngeal cancer (OPC) among women attending primary care services.

Methods

The cross-sectional study was conducted from September to December 2022 in adult women attending three primary care services in Italy, who were invited to complete a self-administered questionnaire.

Results

Overall, 34.7% of participants know that OPC is HPV-associated; knowledge was higher among women who had personal, familiar or friends' experience of cancer, and who reported to often seek dental care, whereas it was lower in older women. The perception of risk of developing OPC was high for 26.4% of women and was higher in those who had experienced STD, who knew that early sexual debut is a risk factor for OPC, and who considered useful the role of dentists on the provision of information about OPC. Only 22.5% had received HPV vaccination, but 62% intended to receive it in the future. Moreover, 63.2% believe that HPV vaccination is very useful to prevent OPC and only 27% are concerned about health consequences of HPV vaccination.

Conclusion

These findings indicate that women's awareness of the role of HPV infection in the development of OPC is not satisfactory and underline the role that dentists might have in improving their patients' awareness on HPV related OPC.
