Abstract：
UNASSIGNED: For more than 150 years, dental amalgam (DA) has been popular as a dental restorative material. Many organizations oppose its use due to perceived toxicity and environmental concerns. Hence, this study aimed to explore the continued use of DA from a South Indian dental practitioners\' perspective.
UNASSIGNED: This cross-sectional study was conducted among fifty-two private and public dental practitioners of Udupi district in Southern India. A self‑administered questionnaire was distributed, that involved assessment of their preferences, continuation of use and concerns of using DA as a restorative material. The percentage contribution of each variable was calculated. Preferences for continuation of use of silver amalgam based upon the age, experience and mercury toxicity as a risk factor were analyzed using Students-t test and Fisher\'s Exact Test test.
UNASSIGNED: Most dentists were satisfied (87%) with the results of the DA, found minimal failures (96%) and found DA more economical (89%). More than half (54%) of the participants reported that they would not continue the use of DA owing to mercury toxicity and environmental concerns. Dentists with higher age and longer clinical experience preferred continuation of DA.
UNASSIGNED: Despite satisfaction with DA for its minimal failure, longevity and affordability, the authors found that most practitioners did not prefer its continued usage. This highlights their concerns over mercury toxicity and soft tissue lesions and accentuates their community social responsibility. There is also an urgent need to educate dentists on mercury hygiene, mercury waste management and disposal.

摘要：
背景：150多年来，牙科用汞合金(DA)作为牙科修复材料已经很受欢迎。然而，由于感知到的毒性和环境问题，许多组织反对使用它。因此，本研究旨在从南印度牙科医生的角度探讨DA的持续使用。方法：这项横断面研究是在印度南部Udupi区的52名私人和公共牙科医生中进行的。分发了一份自我管理的问卷，这包括评估他们的偏好，继续使用和使用DA作为修复材料的担忧。计算每个变量的贡献百分比。根据年龄继续使用银汞合金的偏好，使用Students-t检验和卡方检验分析了经验和汞毒性作为危险因素。结果：大多数牙医对DA的结果感到满意（87％），发现故障最少(96%)，发现DA更经济(89%)。超过一半（54％）的参与者报告说，由于汞毒性和环境问题，他们不会继续使用DA。年龄较高，临床经验较长的牙医首选继续使用DA。结论：尽管对DA的最小失败感到满意，长寿和负担能力，作者发现，大多数从业者并不喜欢继续使用它。这凸显了他们对汞毒性和软组织病变的担忧，并强调了他们的社区社会责任。还迫切需要对牙医进行汞卫生教育,汞废物管理和处置。
