To investigate the preferences of general dental practitioners (GDPs) and endodontists in using endodontic intra-canal medications (ICMs).
This observational and descriptive study was conducted in 2014 in the western province of Saudi Arabia. Following ethical clearance and 2 pilot studies, a web-based questionnaire was electronically sent to 375 randomly and systematically selected GDPs and all endodontists in the western province (n=49). An accompanying e-mail explained the study's aims and confirmed that the data yielded would remain confidential. The responses were collected, and the data was analyzed using the Chi-square test at p=0.05.
Significantly, the highest proportion of respondents (53.7%) reported disinfection of the root canals as the main function of ICMs. Calcium hydroxide (CH) was the preferred material of the majority of those who used the same ICM in all cases (85.7%). While the vast majority of all endodontists (87.5%) used CH after pulp extirpation, 48.5% of GDPs used formocresol (p less than 0.001). Almost 30% of those who used ICMs after pulp extirpation did not do so after cleaning and shaping of vital cases. Most endodontists used CH (62.5%) and antibiotics (37.5%) in necrotic pulp cases without apical lesions, which were significantly greater than those of GDPs who did the same (43.8% and 17.2%).
Participants were aware that the main function of ICMs is disinfection of the root canal system. However, it is clear that GDPs should reduce their reliance on phenol- and formaldehyde-based medications. There was a distinct trend toward the use of ICMs, especially CH, in necrotic pulp cases.
调查普通牙科医生（GDPs）和牙髓病医生在使用根管内药物（ICMs）方面的偏好。
这项观察性和描述性研究于2014年在沙特阿拉伯西部省份进行。在获得伦理批准并完成两项预试验后，通过网络向随机系统选取的375名GDPs和该西部省份的所有牙髓病医生（n = 49）发送了调查问卷。随附的电子邮件解释了研究目的，并确认所产生的数据将保密。收集回复，并使用卡方检验对数据进行分析，p值设定为0.05。
值得注意的是，最高比例的受访者（53.7%）报告根管消毒是ICMs的主要功能。氢氧化钙（CH）是在所有病例中都使用相同ICM的大多数人的首选材料（85.7%）。虽然绝大多数牙髓病医生（87.5%）在牙髓摘除后使用CH，但48.5%的GDPs使用甲醛甲酚（p小于0.001）。在牙髓摘除后使用ICMs的人中，近30%在活髓病例的清理和成形后未使用。大多数牙髓病医生在无根尖病变的坏死牙髓病例中使用CH（62.5%）和抗生素（37.5%），这显著高于使用相同方法的GDPs（分别为43.8%和17.2%）。
参与者意识到ICMs的主要功能是根管系统消毒。然而，很明显GDPs应减少对酚类和甲醛类药物的依赖。在坏死牙髓病例中，使用ICMs尤其是CH有明显趋势。
