Dental operatory requires handling of numerous toxic fluids such as denture acrylic monomer, alcohol and formalin for effective oral care delivery. The efficacy and responsible handling of such fluids has not been analyzed among Indian dentists and this study aims to address this lacunae.
Closed ended questionnaire was distributed through email to Indian dentists in July 2012. After inclusion/exclusion criteria, 1484 practitioners constituted the study group with a response rate of 52%.
SPSS(®) Version 17.0 (SPSS-IBM Inc., IL, USA) was used to carry out statistical analysis. Descriptive statistics were presented. Chi square test was used to identify the association between the parameters; P ≤ 0.05 was considered as statistically significant.
Males (80.8%), undergraduates (78%), exclusive practitioners (81.2%), urban practitioners (68.5%) were the predominant respondents. Predominant of the respondents (97%) used local anesthetic (LA) from bottles. Eight percent have encountered instances of injecting formalin instead of LA in their settings. Safe disposal rules and regulations (P ≤ 0.05), opinion on injecting the other fluids instead of LA as a severe negligent act (P ≤ 0.05) were statistically significant between age groups. Educational status did not appear to influence the outcome. Only a third of the respondents were aware of the rules and regulations for safe disposal of empty LA bottles while 49.1% were not aware of them and willing to learn.
The lacunae in responsible handling of toxic fluids need to be addressed to prevent inadvertent and negligence suits against dentists, highlighting the need through continuing dental education programmes.
牙科诊疗操作需要处理多种有毒液体，如义齿丙烯酸单体、酒精和福尔马林，以有效提供口腔护理。印度牙医对这些液体的使用效果及正确处理方式尚未得到分析，本研究旨在填补这一空白。
2012年7月通过电子邮件向印度牙医发放封闭式问卷。经过纳入/排除标准筛选后，1484名从业者组成研究组，回复率为52%。
使用SPSS(®) 17.0版软件（SPSS-IBM公司，伊利诺伊州，美国）进行统计分析。呈现描述性统计结果。采用卡方检验确定参数之间的关联；P≤0.05被视为具有统计学意义。
主要受访者为男性（80.8%）、本科生（78%）、个体从业者（81.2%）、城市从业者（68.5%）。大多数受访者（97%）使用瓶装局部麻醉剂（LA）。8%的受访者在其工作环境中曾遇到过将福尔马林误注入而非LA的情况。安全处置规则和条例（P≤0.05），以及关于将其他液体误注入而非LA视为严重疏忽行为的看法（P≤0.05）在不同年龄组之间具有统计学意义。教育程度似乎未对结果产生影响。只有三分之一的受访者知晓空LA瓶安全处置的规则和条例，而49.1%的受访者对此不知情且愿意学习。
需要解决有毒液体正确处理方面的空白，以防止针对牙医的意外和疏忽诉讼，通过继续牙科教育项目突出这一需求。
