58th ORCA

Dr Sugiyama presented “Survey of How Relevant ICDAS-II Is to Japanese General Practitioners Who Focus on Preventive Dentistry” at the 58th ORCA in Kaunas, Lithuania. The following is the abract (which is available at http://content.karger.com/ProdukteDB/produkte.asp?doi=10.1159/000328514).


The purpose of this study was to check how much Japanese general dental practitioners who regard preventive care as important know about ICDAS-II. A questionnaire was sent to 1,206members of the Japan Health Care Dental Association (JHCDA),which is a group of general practitioners dedicated to modern patient-centered holistic oral health care. JHCDA developed visual materials named  ”Photo Panel” to depict the categories of caries proposed by ICDAS-II through oral and X-ray photos. Thiswas sent with the questionnaire. A total of 320 (26.6%) members returned the questionnaire. Among those, 210 (65.6%) had heard about ICDAS-II, and 184 (57.5%) had some specific knowledge about it. More than 90% of those who responded said that Photo Panel is a useful aid when using ICDAS-II in their clinics. An additional questionnaire was sent to the 160 members who had already had Photo Panel, and they were asked about advantages and difficulties of introducing ICDAS-II into their clinic. A total of100 clinicians returned it. Positive changes in their clinics afterintroducing ICDAS-II were as follows: more careful observationof tooth surfaces (58.8%), sharing the idea of various stages of caries amongst members of their clinics (41.2%), encouraging explanation about caries to patients (41.2%). On the other hand, the negative comments were that ICDAS-II required proper training to match the ICDAS grades with clinical practice (68.1%) and could lengthen treatment time (44.7%). The response rate was disappointing especially among a group of committed preventive dentistry, but non-responders might be reluctant to change established behavior on the basis of newly developed guidelines. In conclusion, greater efforts are needed to persuade Japanese general practitioners of the usefulness of ICDAS-II, but the visual materials are helpful.This study was supported by The Japan Health Care Dental Association.


Overall the presentation was well received. The questions asked were “Why the low response rate?” and “Was there any information about ICDAS given to members prior to this survey/questionnaire” .  The low rate, explained, is due to the fact that “We are a group of practitioners, so some are more interested in Perio or Orthodontics, so Caries–hence ICDAS, is not necessarily every member’s primary interest–that’s probably why.” To the latter he answered by explaining the process and events JHCDA has held prior to the question to disseminate info about ICDAS.

Being one of a few presenters who are clinical practitioners, his poster presentation attracted quite a few people and the ICDAS photopanels were gone in a few minutes…so overall success! We shall try to incorporate advice and reactions we received during ORCA and improve our ICDAS activities and implementation process.
