Systemic Health vs Oral Health
Speaker 2This is let's Talk Oral Health the expert podcast for oral health professionals brought to you by Sunstar .
Speaker 1Hello everyone , Welcome to Sunstar let's Talk Oral Health Expert Series . This is the Q&A session following the episode we held on the systemic approach in the 360 strategy to prevent periodontal and peri-implant diseases . We invited back Professor Cara to answer directly to the questions you , our audience , had . Welcome back , Clotilde , and thank you for taking the time to answer to our audience these questions .
Speaker 2Hello Rachel . Thank you for inviting me . I'm very happy to be here and answer the questions .
Speaker 1Thank you for inviting me . I'm very happy to be here and answer the questions . Our conversation on the impact of systemic health on oral health stirred up some questions and we are eager to hear your complementary insights on the topic . Let's dive right into it with the first question . The first question is about peri-implant treatment efficacy , or rather lack of it . Relates to your paper and what you said about primordial and primary prevention of peri-implantitis . There are many similarities between periodontal and peri-implant diseases , even in the risk factors to control and in their prevention more or less evident . So if there are so many similarities , why are the peri-implantitis treatments less effective than the purulentitis ones ? This is the question that we receive .
Speaker 2It's a very good question and indeed it's complex to treat peri-implant diseases . We know that indeed our treatments are less effective and the first reason is because we do not know today the exact causes of peri-implant disease . So we cannot target the precise etiology of this disease with our treatment . And this is probably the first reason why treatment is less effective . But we can cite several factors that may explain the fact that treatment are not so efficient . The first one are anatomical reasons . We know that the anatomy of the tissue surrounding an implant are not exactly the same as the periodontal tissue surrounding a tooth . So this is the first reason and we have to think that the implant is an artificial structure and has specific characteristics . For example the implant surface . We know the rough surface of titanium can harbor more bacteria than other surfaces . And also we have to think about the abatement and the structure of the implant .
Speaker 2Support is prosthesis . Sometimes it's not easy to probe this space and not even to clean this space for the patient but also for the clinicians . So all these factors will make the environment around the implant more complex and difficult to clean , richer of bacteria . And then we can also mention the composition of the biofilm surrounding the implant and in the specific area of the connection between the implant , the abatement and the level of the bone . So here there are some specificities that may explain , once again , the lower response to treatment . And also we have to consider that whenever the inflammatory lesion begins around an implant , it will develop much faster than around the tooth , and so the bone loss severity will also guide the treatment choice and the availability of treatment option to treat upper implantitis . So , because we are not so effective with our treatment and sometimes we even have to be aggressive , more aggressive with periodontal treatment around implants , the early detection of peri-implant disease is an abrupt intervention , a cardinal , trying so to focus on prevention of the progression of the disease and try to maintain the dental implants .
Speaker 1So , because there are so many points to be still evident and not necessarily fully controllable , the best strategy remains prevention , through a primordial or primary or other . Okay , thank you for this first answer . Let's move on to the second question , then , or rather a group of questions that we received about the host modulation techniques , with the role of nutrition and micronutrition in decreasing the inflammatory burden . You said during the episode that the link between obesity and periodontal diseases is even stronger at a young age , between age 18 and age 34 . Why is that ?
Speaker 2So the link between periodontitis and obesity is quite complex . Obesity is a chronic disease and is linked to several factors . We can mention that the inflammatory burden associated with obesity , so the low-grade systemic inflammation characteristic of this patient , may explain the exacerbation of periodontitis . But we also have in obese patients insulin resistance , so the metabolic problem that will also contribute to periodontal disease development or progression . And then we have to think that this type of patient may have poor lifestyle habits , like poor diet lifestyle habits like poor diet , low physical activity , and these are all factors that may contribute to the aggravation of periodontal disease .
Speaker 2And once again we have to look at the whole pictures , clinical pictures . So an obese patient , depending on the age , may also have hormonal changes and other comorbidity like , for example , obstructive sleep apnea or diabetes . So it may be quite complex to understand what is the contribution of obesity for periodontal diseases and what are the contributions of other risk factors . So statistically , in younger age , so like between 18 and 34 , we have less chance to find comorbidities . So the obese patient may have less comorbidities , may be exposed to a lower number of risk factors , and so the contribution of obesity to toward periodontitis is stronger . We can say that obesity is considered a risk factor for periodontal disease at all ages , but at a younger age the contribution of obesity may be stronger be stronger .
Speaker 1So it means that it depends actually on the weight of the different factors that are to be taken into account , including the age here , for example , or the obesity but obesity for sure has an impact at any age . It's just more or less depending on all the factors that have to be factored in .
Speaker 2Exactly , it's a sort of a cumulative exposure . So for sure , when we are older we are exposed to more risk factors for a longer time . So the contribution of risk factors is more difficult to assess . When we are younger , just obese , but we are not smoking , the impact of obesity appears stronger .
The Link Between Diet and Sleep
Speaker 1Talking about the link between obesity and periodontal diseases . The next question we received was about diets , and the question was can you detail the diets that reduce gingival inflammation versus the ones that are pro-inflammatory and detail the evidence behind ?
Speaker 2Yes , diet is a very important factor to consider today when we look at the risk profile of our patient and when we want to have a systemic approach in our periodontal treatment . So all nutrients , food , that have pro-inflammatory properties should be avoided or limited , whereas all food that have anti-inflammatory property and should be promoted . So we can make the example , for instance , of the Mediterranean diet , which is known to be rich in fruit and vegetables , seeds , olive oil and few intake of red meat , for example , and fish of red meat , for example , and fish and saturated fat . So this is considered a type of diet that has anti-inflammatory properties . On the contrary , western-type diet , rich in processed food , frozen meals , very often some snacks , packaged snacks that are rich in sugar and carbohydrates these are considered to be really pro-inflammatory , so not very good for gum health and periodontal diseases . Now we start to have literature saying that really consuming a high quantity of processed food is not good for our health . Start to have literature saying that really consuming a high quantity of processed food is not good for our health .
Speaker 1There are probably also other types of diets that are more or less evidence , but we hear a lot about this Mediterranean diet . What is the level of evidence behind this one ? Is it for sure , something that works ?
Speaker 2Unfortunately , the level of evidence is still limited on the topic . We cannot recommend a type of diet toward the benefit of our health , but we can recommend the intake , for instance , of five portions of fruit and vegetables to limit the intake of carbohydrates and sugar , and also processed food for the benefit of our health .
Speaker 1Linking to that , there is a question about specific vitamins that improve gum health , that are anti-inflammatory , and their mode of action . What would you say about the type of vitamins that have these kind of actions ? What are they ?
Speaker 2We can cite three main vitamins that have been linked to periodontal health . The first one for sure is vitamin C . It is known since centuries that it is really important for gum health . Whenever we have a deficiency of vitamin C , we have bleeding gums , gingivitis , periodontal disease that may appear , because it's very important for the synthesis of collagen at the level of the gums , so it will support the tissue integrity and also have antioxidant properties . So it's very good for gum health . Also , vitamin E is very good because it has antioxidant properties . And finally , we can cite vitamin D , which is essential for the bone metabolism , but it's also a very important role in the immune function and anti-inflammatory response . So , in general , vitamins are important because they will have to through mainly three main pathway the anti-inflammatory , antioxidant properties , the tissue integrity and the immune response . So they will boost the immune response .
Speaker 1But if these three vitamins that you mentioned C , e and D are effective , should that mean that the dentist should prescribe vitamin themselves or leave that to the nutritionist ?
Speaker 2It's a very important question because we try to see if the supplement of vitamin will improve , for example , the response to a periodontal treatment , and indeed the literature is quite controversial . Why ? Because it's not so easy to have an effect just with a supplement of vitamin E or C or D , because it depends if the patient , the individual patient , is in a situation of vitamin deficiency which need to be treated , or not . So give some supplement to a patient has no reason . There is no indication to do that . It really had to be a target to some specific patient that will require this type of supplementation . And I think it's important to work with nutritionists and to be able to refer patients that may be in suspect of a deficiency for vitamins in order to work in a multidisciplinary way in this systemic approach .
Speaker 1Yeah , collaboration with other professionals to ensure that we cover all the aspects to prevent the disease . We have come to questions about sleep , and this is the last set of questions that we received . You talked about sleep and obstructive sleep apnea . During our conversation , someone said that they did not know how to explain to their patients how sleep and periodontal peri-inflammatory diseases are linked , without being far-fetched or fear-mongering . So the question would be maybe can you tell us how you present this link yourself to your own patient ?
Speaker 2Is it true that sleep and oral health appears distant , but indeed they are very much linked . So it's important for dentists to start talking about sleep with their patients . And how can we do it ? And how can we do it ? First of all , we have to provide clear information and evidence-based information to our patient . We have to avoid all exaggerated claims that can make fear , of course , and we have to try to use scientific data to motivate patient toward a behavioral change if needed . I mean if we understand the patient as a behavioral change . If needed , I mean if we understand that the patient has a poor sleep , has sleep disorders , and we can easily have the suspect clinically , because sometimes the patient falls asleep as soon as he's on the dentist chair during the treatment or snores , even snoring , and report to be very tired during the day . So all these key elements , together with other clinical elements , can make us ask a question do you sleep well ? Do you snore ? Do you suffer of obstructive sleep apnea ? For example , do you make breathing pauses during sleep ?
Speaker 2And it is important to do that because sleep is a key element of a healthy lifestyle , so , together with regular physical activity , the effect to avoid exposure to tobacco product , the effect of managing stress and have a balanced diet .
Speaker 2We also have , as a key element of healthy lifestyle , an adequate amount and a good quality of sleep . It's primordial to preserve health . We do know that . So , starting from the basic concept of healthy lifestyle , where we have to stress the importance of oral hygiene , the daily behavior of good oral hygiene to preserve oral health , to prevent oral diseases and periodontal diseases , we can , starting from that and arriving to talk about sleep and the importance to maintain and preserve a good night of sleep for health in general and for gamma health as well . Serve a good night of sleep for health in general and for gamma health as well . So emphasizing the importance of sleep is the first part , but then we have to encourage the patient to this kind of healthy sleep habits , so what we call a sleep hygiene , and then offer support and resources so advise the patient where this information can be found and eventually refer the patient to a specialist if needed .
Speaker 1Do you have an example of a website where a patient could find this information ?
Speaker 2Well , there are several types of websites , but what I can advise is to look at the website of the scientific societies , because there are more evidence-based and the information are , of course , evidence-based . So are reputable sources and any different countries , as usually has a national scientific society dealing with sleep medicine and are usually very useful resources for information .
Speaker 1Oh yes , of course , thanks . The last question that we received around sleep was about obstructive sleep apnea that you mentioned during the conversation . Again , the question is what explanation to give to patients to link it to periodontal diseases . Again , very pragmatic , chair-side explanation to give to our patients . What would you say to give to other patients ?
Speaker 2What would you say ? Obstructive sleep apnea is a common sleep disorder . Prevalence data estimate that 1 billion of people worldwide are suffering from obstructive sleep apnea and most of them are undiagnosed , so untreated . This is because the first symptoms and sign and symptoms of obstructive sleep apnea are neglected by the patient and by the physician most of the time , because the first sign and symptoms are just fatigue , tiredness during the day , excessive daytime sleepiness , the fact of snoring during the night , so the sleep is not restorative night , so the sleep is not restorative , but the fact of being tired is quite common and unfortunately is so underestimated . But dentists can see these signs and symptoms and also use a questionnaire that has been validated to screen for obstructive sleep disorder , so to identify the patient that may be at risk of this disease or even be already in the need of treatment .
Speaker 2We must remember that obstructive zipapnea is linked to obesity , cognitive impairment , higher risk of cancer , higher risk of mortality .
Speaker 2So it's a very severe disease that needs to be diagnosed , needs to be followed up and treated , of course , and recent evidence suggests that among all these conditions related to obstructive zipapnea we can add periodontitis . Obstructive zipapnea patient would be actually almost two times at increased risk of having severe periodontitis than patients without obstructive zip apnea , and this is linked , probably , to the inflammatory burden . Of course I mentioned obesity , I mentioned a disease that's linked to a low-grade systemic inflammation , which for sure will contribute to the inflammatory burden , also at the level of the periodontal tissue , but is also linked to a specific way , which is the oral microbiota composition . Patients suffering from obstructive zipapnea usually breathe with their mouth during sleep , they snore and have less salivary flow , so they accumulate plaque , dental plaque , more important than patients that sleep well and they do not breathe with their mouth during sleep . And they also have a biofilm or a biofilm rich in periodontal pathogens or a biofilm rich in periodontal pathogens . So this kind of element will probably explain why patients with obstructive sleep apnea are at increased risk of periodontal diseases .
