Knowledge, awareness and implementation of sustainable dentistry by dental faculty lecturers in clinical dental practice: a preliminary study

Dentists, as professional oral health care providers, frequently utilize disposable dental products such as plastic cups, toothpaste tubes, dental floss, and plastic dental instruments, leading to the generation of dental waste. Dental faculty lecturers, as primary educators of dental students, play a key role in serving as role models. Their knowledge, awareness, and application of sustainable dentistry practices can significantly contribute to promoting sustainable dentistry among future dentists. The aim of this study was to identify the knowledge, awareness, and implementation of green dentistry among dental faculty lecturers in clinical dental practice. This preliminary study was conducted through a survey involving faculty lecturers at a private dental school in Surabaya, Indonesia. A total of 14 dentists participated as respondents. They were asked questions regarding their awareness, knowledge, and implementation of green dentistry in clinical settings. The majority of respondents reported understanding the concept of green dentistry and expressed awareness of its importance. However, they encountered challenges in its implementation, primarily due to high associated costs. Amalgam waste management and paper recycling practices were not adequately performed, although most respondents had already adopted computer-based record systems. In terms of infection control management, respondents generally exhibited a positive attitude in support of green dentistry. Nevertheless, the use of disposable cups remained relatively high. Energy and water-saving practices were reasonably well implemented, with the exception of the use of renewable energy sources and motion-sensor faucets. The implementation of sustainable practices in energy, water usage, infection control, and waste management were not consistent among all dental faculty lecturers. This highlights the need for enhanced education on sustainable dentistry at the undergraduate level, as well as outreach programs and regulations to support the adoption of sustainable dentistry practices among dental professionals.
