The purpose of this study was to assess the level of compliance with dental radiography quality assurance recommendations on the part of dental practitioners in the state of North Carolina and to determine whether the age of the practice was an influential factor affecting compliance.
On-site survey inspections by state officials using measurement devices and questionnaires were used to assess x-ray machine parameters and gather information about quality assurance practices in private offices in the state of North Carolina.
There were approximately three intraoral units per facility, with an average entrance skin exposure of 267 mR per bitewing radiograph. There were no significant differences associated with the age of the practice in quality assurance practices except with respect to the type of processor used: dentists who had been in practice for more than 20 years used manual processing more frequently than those who had been in practice for less than 20 years (p = 0.001).
Most practices showed a high level of compliance with equipment function requirements. North Carolina dentists are making an effort to comply with the American Academy of Oral and Maxillofacial Radiology recommendations. However, the use of faster film and rectangular collimation was much less than expected. Only 9% of the participants reported using E-speed film exclusively, and only 7.33% reported using rectangular collimation.
本研究旨在评估北卡罗来纳州牙科从业者对牙科放射摄影质量保证建议的遵守程度，并确定诊所的经营年限是否是影响遵守情况的一个因素。
州官员使用测量设备和问卷进行现场调查检查，以评估X光机参数，并收集北卡罗来纳州私人诊所质量保证措施的相关信息。
每个机构约有三台口腔内X光机，每张咬合翼片的平均皮肤入口照射量为267毫伦琴。除了所使用的冲洗机类型外，在质量保证措施方面，诊所经营年限没有显著差异：执业超过20年的牙医比执业不足20年的牙医更频繁地使用手工冲洗（p = 0.001）。
大多数诊所对设备功能要求的遵守程度较高。北卡罗来纳州的牙医正在努力遵守美国口腔颌面放射学会的建议。然而，更快胶片和矩形准直的使用比预期少得多。只有9%的参与者报告仅使用E速胶片，只有7.33%的参与者报告使用矩形准直。
