To evaluate and compare the frequency of common operator errors seen on panoramic radiographs in dental private practices and in the dental hospital (taken by informally and formally trained operators, respectively) in Trinidad and Tobago.
One thousand panoramic radiographs of patients over the age of 10 years were included in this study. These comprised 500 from the dental hospital and 500 from dental private practices. The radiographs were reviewed using standardized criteria to identify the most common operator errors.
There were only 21 (4.2%) error free radiographs in the dental private practice sample and 29 (5.80%) in the dental hospital sample. Frequencies of specific errors were significantly higher in the dental private practice sample in each category except for "Chin tipped too low" (Chi-square p < 0.05)
This study supports the need for the introduction of statutory guidelines with respect to the use of ionizing radiation in dentistry in Trinidad and Tobago and in particular, the implementation of formally assessed dedicated dental radiography training for all operators of dental X-ray equipment.
评估并比较特立尼达和多巴哥私立牙科诊所及牙科医院（分别由非正式和正式培训的操作人员拍摄）全景X光片上常见操作人员错误的发生率。
本研究纳入了1000例10岁以上患者的全景X光片。其中500例来自牙科医院，500例来自私立牙科诊所。使用标准化标准对X光片进行审查，以确定最常见的操作人员错误。
私立牙科诊所样本中仅有21张（4.2%）无错误X光片，牙科医院样本中有29张（5.80%）。除了“下巴过低”外，私立牙科诊所样本中各类特定错误的发生率在各类别中均显著更高（卡方检验p<0.05）。
本研究支持在特立尼达和多巴哥出台有关牙科电离辐射使用的法定指南的必要性，特别是为所有牙科X光设备操作人员实施经过正式评估的专门牙科放射摄影培训。
