Root canal treatment in general practice in Sudan.

AIM: 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.
METHODOLOGY: A questionnaire was posted to 55 registered dental practitioners. Completed questionnaires were analysed in term of simple summary statistics.
RESULTS: 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.
CONCLUSIONS: 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.
