OBJECTIVE: To test for an association of periodontitis and tooth loss with rheumatoid arthritis (RA). METHODS: The third National Health and Nutrition Examination Survey (NHANES III) is a nationally representative cross-sectional survey of noninstitutionalized civilians. We included participants aged > or = 60 years who had undergone both musculoskeletal and dental examinations. RA was defined based on American College of Rheumatology criteria. Dental examinations quantified decayed and filled surfaces, missing teeth, and periodontitis. Periodontitis was defined as at least 1 site exhibiting both attachment loss and a probing depth of > or = 4 mm. We classified dental health status as (1) no periodontitis, (2) periodontitis, or (3) edentulous (i.e., complete tooth loss). We performed multivariate multinomial logistic regression models with dental health status as the dependent and RA as the independent variables. RESULTS: The sample consisted of 4461 participants, of whom 103 were classified as having RA. Participants with RA had more missing teeth (20 vs 16 teeth; p < 0.001), but less decay (2% vs 4%; p < 0.001) than participants without RA. After adjusting for age, sex, race/ethnicity, and smoking, subjects with RA were more likely to be edentulous [odds ratio (OR) 2.27, 95% confidence interval (CI) 1.56 3.31] and have periodontitis (OR 1.82, 95% CI 1.04 3.20) compared with non-RA subjects. In participants with seropositive RA there was a stronger association with dental health status, in particular with edentulism (OR 4.5, 95% CI 1.2 17). CONCLUSION: RA may be associated with tooth loss and periodontitis.
If your salivary glands still produce some saliva, you can stimulate them to make more by chewing gum or sucking on hard candy. However, gum and candy must be sugar free because dry mouth makes you extremely prone to cavities. Take sips of water or another sugar free drink often throughout the day to wet your mouth, especially when you are eating or talking. Note that you should take sips of water--drinking large amounts of liquid throughout the day will not make your mouth any less dry. It will only make you urinate more often and may strip your mouth of mucus, causing even more dryness. You can soothe dry, cracked lips by using oil- or petroleum-based lip balm or lipstick. If your mouth hurts, the doctor may give you medicine in a mouth rinse, ointment, or gel to apply to the sore areas to control pain and inflammation.
If you produce very little saliva or none at all, your doctor might recommend a saliva substitute. These products mimic some of the properties of saliva, which means they make the mouth feel wet, and if they contain fluoride, they can help prevent cavities. Gel-based saliva substitutes tend to give the longest relief, but all saliva products are limited since you eventually swallow them.
At least two drugs that stimulate the salivary glands to produce saliva are available. These are pilocarpine and cevimeline. The effects last for a few hours, and you can take them three or four times a day. However, they are not suitable for everyone, so talk to your doctor about whether they might help you.
People with dry mouth can easily get mouth infections. Candidiasis, a fungal mouth infection, is one of the most commonly seen in people with Sjogren's. It most often shows up as white patches inside the mouth that you can scrape off, or as red, burning areas in the mouth. Candidiasis is treated with antifungal drugs. Various viruses and bacteria can also cause infections; they're treated with the appropriate antiviral or antibiotic medicines.
