Smoking cessation may decrease risk of tooth loss

dfdfdSmoking cessation has been shown to have a positive impact on the outcome of periodontal therapy. So far, no systematic review has evaluated the effect of smoking cessation on tooth loss. Researchers from the University of São Paulo School of Dentistry investigated this topic and found that former smokers show a decreased risk compared with current smokers. Analysis from longitudinal studies showed that the rate of tooth loss in former smokers is similar to that in those who have never smoked. Moreover, current smokers have a risk of tooth loss twice as high as that of those who have never smoked. According to the researchers, the most plausible biological explanation for the increased risk of tooth loss in smokers is the destruction of the periodontal supporting tissue. “After the subject stops smoking, it takes some months for the body to return to its normal immune-inflammatory conditions,” explained study author Dr Cláudio Mendes Pannuti, “After smoking cessation, the periodontal conditions slowly return to the same level of never smokers. But even after one to two years, the benefits are small, as demonstrated by a study from my research group from 2014 and by a study from the University of Newcastle upon Tyne from 2005. Thus, it may take many years—between five to ten—of abstinence for the risk of tooth loss in smokers to return to the level of never smokers”. The study, entitled ‘Effect of smoking cessation on tooth loss: A systematic review with meta-analysis’ was published in BMC Oral Health.



Link between obesity and gum disease

dfdfdA new study explores the effect of obesity on non-surgical periodontal care and evaluates potential pathways that may illustrate the connection between the two conditions. The connection between obesity and gum disease isn't as simple as cause and effect, said Prof. Andres Pinto, co-author of the study, published in the British Dental Journal. Instead, the relationship centres on what both diseases have in common: inflammation. Examining a plethora of existing studies, researchers found that data showing increased body mass index (BMI), waist circumference and percentage of body fat are associated with an increased risk of developing gum disease. They concluded that changes in body chemistry affect metabolism, which in turn causes inflammation – something present in both maladies. This information can inform how healthcare professionals plan treatments for patients suffering from obesity and/or gum disease, Pinto said. "Oral healthcare professionals need to be aware of the complexity of obesity to counsel their patients about the importance of an appropriate body weight and maintaining good oral hygiene," he said. Pinto said further research on the relationship between gum disease and obesity is needed, noting there is limited evidence to recommend changes in treatment planning. "There is a thought, from the clinical perspective, that if you treat one of the issues, it may impact the other," he said, "This is the big question. For example, if we treat obesity successfully, will this impact periodontal disease to the point of being of clinical relevance compared to control population? The jury is still out”.



Brush your teeth to protect the heart

dfdfdBrushing teeth frequently is linked with lower risks of atrial fibrillation (irregular heartbeat) and heart failure, according to a study published in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC). Previous research suggests that poor oral hygiene leads to bacteria in the blood, causing inflammation in the body. Inflammation increases the risks of atrial fibrillation and heart failure. This study examined the connection between oral hygiene and occurrence of these two conditions. The enrolled 161,286 participants from the Korean National Health Insurance System aged 40-79 with no history of atrial fibrillation or heart failure. Participants underwent a routine medical examination between 2003 and 2004. Information was collected on height, weight, laboratory tests, illnesses, lifestyle, oral health, and oral hygiene behaviours. During a follow-up 10.5 years later, 4,911 (3%) participants developed atrial fibrillation and 7,971 (4.9%) developed heart failure. Tooth brushing three or more times a day was associated with a 10% lower risk of atrial fibrillation and a 12% lower risk of heart failure. While the study did not investigate mechanisms, one possibility is that frequent tooth brushing reduces bacteria in the pocket between the teeth and gums, thereby preventing translocation to the bloodstream. Senior author Dr Tae-Jin Song of Ewha Womans University, Seoul, Korea noted that as an observational study, it does not prove causation. An accompanying editorial states: "It is certainly too early to recommend tooth brushing for the prevention of atrial fibrillation and congestive heart failure."
