The aim of this study was to evaluate the practice and depth of knowledge of root canal treatment by dental practitioners in Khartoum, the capital city of Sudan, in order to improve the current status of endodontic therapy.
A questionnaire was posted to 55 registered dental practitioners. Completed questionnaires were analysed in term of simple summary statistics.
A total of fifty-two (95%) practitioners responded. Eighty-five per cent of the respondents indicated that they performed root canal treatment for their patients. Of these, 84% included molars in their activity. Amongst those who carried out root canal treatment, only one practitioner used rubber dam for isolation, whilst the remainder used cotton wool rolls. The majority of respondents (80%) used hydrogen peroxide to irrigate canals during treatment. Three-quarters of practitioners used formocresol as an inter-appointment medicament. The stepback preparation technique was the method of choice for 98% of respondents. All practitioners used hand instruments to prepare root canals and all used gutta-percha for obturation; three-quarters of them used cold lateral condensation for all or some cases. The average number of radiographs routinely taken for root canal treatment was three. Only 73% used radiographs for measuring the working length. Ninety-five per cent of respondents indicated that they usually completed a root filling in three or more visits. Three-quarters of practitioners restored the teeth permanently immediately after the obturation and one-quarter preferred waiting for 1 or 2 weeks.
In Sudan, there are no dental practices limited to endodontics and no postgraduate training programmes. This survey shows the importance of establishing higher specialist training or continuing dental education for practitioners to update their knowledge.
本研究旨在评估苏丹首都喀土穆牙科医生进行根管治疗的实践情况和知识深度，以改善当前牙髓治疗的现状。
向55名注册牙科医生发放问卷。对回收的问卷进行简单汇总统计分析。
共有52名（95%）医生回复。85%的受访者表示他们为患者进行根管治疗。其中，84%的治疗活动包括磨牙。在进行根管治疗的医生中，只有一名医生使用橡皮障进行隔离，其余医生使用棉卷。大多数受访者（80%）在治疗期间使用过氧化氢冲洗根管。四分之三的医生使用甲醛甲酚作为复诊间封药。98%的受访者选择逐步后退预备技术。所有医生都使用手动器械预备根管，所有医生都使用牙胶进行充填；其中四分之三的医生在所有或部分病例中使用冷侧方加压充填法。根管治疗常规拍摄的X线片平均数量为三张。只有73%的医生使用X线片测量工作长度。95%的受访者表示他们通常在三次或更多次就诊后完成根管充填。四分之三的医生在充填后立即永久性修复牙齿，四分之一的医生倾向于等待1或2周。
在苏丹，没有专门从事牙髓病学的牙科诊所，也没有研究生培训项目。本次调查表明，为医生开展更高水平的专科培训或继续牙科教育以更新他们的知识非常重要。
