As a periodontist who knows about the numerous barriers we face when talking about possibilities of smoking cessation as part of periodontal treatment I have always expressed empathy even when mentioning serious consequences of smoking, certainly not discrimination. Currently, dentists are not really educated for that task. It is hoped that this might change in future curricula but I’m not sure.
Earlier this year, delegates of the European Federation of Periodontology (EFP) and the International Diabetes Federation (IDF) had met in Madrid for a joint workshop on an update of the Perio-Diabetes link. I had reported on the event and some key findings, quickly posted on the EFP web page, here.
Already on and after 24 August 2017, a Consensus Report by the two organizations was prematurely published, and quickly (temporarily) withdrawn, in the EFP’s Journal of Clinical Periodontology and the IDF’s Diabetes Research and Clinical Practice. I had managed to get a print-out of the not-yet edited (and later withdrawn) draft version published on the JCP Accepted Articles page and had noticed that most of the evidence presented was derived of yet-to-be published review articles based on the workshop proceedings.
The final version of the Consensus Report (Sanz et al. 2017, Early View Articles), including guidelines for patients and health professionals dealing with patients suffering from diabetes and periodontal disease, went online this week, but still references to review papers presented on the occasion of the workshop have a 2017 assignment and are not paginated which may make it more difficult for scientists and clinicians outside periodontology or dentistry to locate the final papers.
To be clear, when it comes to keeping our medical collegues, and in particular diabetologists, interested in the very long-known link between periodontitis and metabolic diseases, proving beneficial effects of periodontal treatment on diabetic control is crucial. All was fine as long as numerous published, small-scale, mostly single-center, and often poorly executed, trials apparently showed that thorough subgingival scaling in patients with both periodontitis and diabetes led to an about 0.4% reduction of glycated hemoglobin (HbA1c), at least after three or four months. As that would in effect spare an additional antidiabetic drug, diabetologists stayed interested. Although results in a few trials indicated that the effect was not long-lasting, i.e., no longer discernable after, say, six months.
After rather devastating negative conclusions made in a systematic review (SR) of the literature regarding the long claimed, possibly causal, relationship between periodontitis and atherosclerotic vascular disease by Lockhart et al. (2012), a highly alerted group of members of our specialty organizations, the Amercian Academy of Periodontology and the European Federation of Periodontology, had hastily organized a joint workshop, in the end of 2012, to fix unwelcome results of a number of large intervention studies by creating new systematic reviews on the Perio-Systemic link. The clear aim was to cement, once and forever, the claim of the number one clinical problem: periodontal disease and general health are closely related.
While the proceedings had been published, open access, in special issues of our main professional journals, the Journal of Clinical Periodontology and the Journal of Periodontology, workshop participants of the EFP presumptuously condensed the 209 pages of the 16, mostly valuable, papers in a nutshell, strangely called Manifesto.
Last weekend, EFP and International Diabetes Federation (IDF) delegates, in partnership with Sunstar, had met in Madrid and had worked on guidelines for dentists, medical doctors and patients with periodontitis and/or diabetes. The EFP website features some key findings when reviewing the literature. In particular, it is claimed that,
evidence suggests that periodontitis patients have a higher chance of developing pre-diabetes and type-2 diabetes and that people with periodontitis and diabetes have more difficulty in keeping their blood-sugar levels under control. Furthermore, patients with both diseases are more likely to develop diabetic complications than people with diabetes without periodontitis.
Current evidence indicates that in people with diabetes, periodontal therapy accompanied by effective self-performed oral hygiene at home is both safe and effective – even in people with poorly controlled diabetes. Similarly, there is consistent evidence that periodontal therapy reduces blood-sugar levels in people with diabetes and periodontitis. (Emphasis added.)
