Letters to the Editor: The content includes several letters discussing various dental topics. The first letter addresses the issue of burnout and mental health among dentists and dental students, highlighting the impact of the COVID-19 pandemic and the need for improved work environments and mental health support. A study on Turkish dentists found that those working in Oral and Dental Health Centers experienced higher levels of burnout compared to those in private clinics or universities. Another study on Brazilian dentists during the pandemic found that those feeling unprepared or scared of the virus were more likely to experience burnout. A study on US dental faculty found that 13.46% exhibited a burnout profile, with higher levels at the nine-year mark. The second letter celebrates the sense of humor of Bernard Smith, a notable figure in dentistry, through a personal anecdote and a memory of his contributions to dental education. The third letter discusses wastewater management in dental practices, noting that dental unit wastewater is now classified as industrial wastewater, requiring more stringent treatment. It suggests energy-extracting technologies to reduce carbon emissions. The fourth letter proposes mandatory sugar packaging warnings to address the health risks associated with excessive sugar consumption, drawing parallels to tobacco control strategies. The final letter discusses the use of rapid maxillary expansion (RME) in treating obstructive sleep apnoea (OSA), highlighting its effectiveness in improving airway space and tongue position. The procedure involves orthopaedic force application and may require surgical assistance in adults.Letters to the Editor: The content includes several letters discussing various dental topics.
