Suicidal Ideation, Lifestyle Factors, and Burnout Syndrome Among Spanish Professionals in Implant Dentistry: A Survey-Based Cross-Sectional Observational Study

<b>Background</b>: Burnout syndrome (BS) is an occupational phenomenon resulting from chronic workplace stress that has not been successfully managed. Although there are underlying causes associated with personal attributes, it is generally linked to external factors within the work environment. The aim of the present study was to investigate the impact of lifestyle factors on BS and its dimensions, as well as on suicidal ideation among Spanish professionals dedicated to implant dentistry. <b>Methods</b>: A cross-sectional observational study was conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. An electronic survey based on the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) was distributed to members of the Spanish Society of Implants. The data were analysed using descriptive statistical methods. <b>Results</b>: A total of 305 participants (20.9%) responded to the questionnaire. Notably, 10.8% of the professionals reported experiencing suicidal thoughts, a factor significantly associated with the presence of BS. The lifestyle factors associated with BS included the following: not engaging in aerobic exercise for at least 30 min per day (<i>p</i> < 0.05), not having hobbies that facilitate mental disconnection from work (<i>p</i> < 0.001), not following a balanced diet (<i>p</i> < 0.0001), having an insufficient social life (<i>p</i> < 0.0001), and experiencing suicidal ideation (<i>p</i> < 0.01). <b>Conclusions</b>: The surveyed dentists generally reported having healthy lifestyle habits. Nevertheless, one in ten professionals acknowledged having experienced suicidal ideation at some point, highlighting a concerning association with BS.
