Perceptions of single-visit and multiple-visit endodontic treatment: a survey of endodontic specialists and general dentists in Hong Kong

J Investig Clin Dent. 2016 Aug;7(3):263-71. doi: 10.1111/jicd.12154. Epub 2015 May 6.


Aim: To study the preference of practice for single- and multiple-visit endodontic treatment by Hong Kong endodontists and general dental practitioners (GDPs), and to investigate their reasons for choosing single- or multiple-visit treatment in their practice.

Method: An anonymous questionnaire was mailed to all 16 registered endodontists and 800 randomly selected GDPs in Hong Kong to explore their preference and reasons for selecting single- or multiple-visit endodontic treatment for their patients. Information on the use of magnifying loupes, microscopes and the number of years they have been in dental practice was also collected.

Results: Eight endodontists and 429 GDPs returned their questionnaires and the response rate was 50% and 53.6% respectively. Among the GDPs, 404 (94.2%) undertook endodontic treatment in their practices. For those performing endodontic treatment, the mean number of years of practice was 23.6 ± 4.8 for endodontists and 15.3 ± 9.1 for GDPs. Seven endodontists (87.5%) used a surgical microscope. For GDPs, only 25 (6.2%) used a surgical microscope and 123 (30.4%) used magnifying loupes during endodontic treatment. Seven endodontists (87.5%) and 375 GDPs (92.8%) predominantly performed multiple-visit treatment. The commonest reasons for choosing multiple-visit treatment for both endodontists and GDPs were the positive effects of interappointment medications (n = 3, 37.5%) and that the tooth to be treated had doubtful prognosis (n = 103, 25.5%). The commonest reason for choosing single-visit treatment for both endodontists and general dentists was that treatment could be completed in one visit (n = 4, 50%) and (n = 127, 31.4%).

Conclusion: Most Hong Kong endodontists and GDPs preferred offering multiple-visit endodontic treatment.
