Abstract
Background/Objectives: Smoking remains a major public health concern, and healthcare professionals (HCPs) play a crucial role in smoking cessation efforts. This study aimed to assess the awareness, knowledge, and smoking behaviors of Italian students and graduates in dental hygiene from different regional areas (Group A) and students in health disciplines at a single university (Group B). Methods: Two separate surveys were conducted using a specifically designed online questionnaire administered to voluntary participants between February and April 2024. The questionnaire collected data on smoking habits, awareness of smoke-free products, sources of information, and perceptions of health effects. Results: A total of 878 questionnaires were completed. While 49.8% of participants had never smoked, 16.3% were regular smokers and 14% were occasional users of either traditional cigarettes or alternative smoke-free products. Awareness of non-combustion products was high, with social circles (74%) and social media (47.9%) being primary sources of information. Users of smoke-free products reported subjective improvements in halitosis, dental discoloration, cough, exercise capacity, and sense of taste. Despite 78% of participants receiving specific training on smoking-related diseases, gaps in knowledge persisted, particularly regarding the toxicological nature of smoking and the role of nicotine in smoking-related diseases. Conclusions: These findings highlight the need for continued education and training on smoking cessation and tobacco harm reduction among future HCPs. Strengthening evidence-based knowledge could enhance their ability to manage smoking-related diseases and promote effective cessation strategies.
