It is a consequence of the complex interactions between periodontal pathogens and their products, which trigger the host inflammatory response, chronic inflammation, and tissue destruction. Chronic systemic low-grade inflammation is involved in numerous diseases, and it is also known that long-lasting inflammation and chronic infections predispose one to cancer. Here, we characterized and compared the subgingival microbiota associated with periodontitis and diagnosis of malignancy in a longitudinal 10-year follow-up study. The study was conducted on 50 patients with periodontitis and 40 periodontally healthy individuals. The recorded clinical oral health parameters were periodontal attachment loss (AL), bleeding on probing (BOP), gingival index (GI), probing depth (PD), and plaque index (PI). Subgingival plaque was collected from each participant, from whic...

We investigated how having/not having periodontitis at baseline in 1985 was associated with purchases of medicines in the long term. The study paradigm is in the oral health-systemic health connections. We hypothesized that periodontitis links to purchases of medicines later in life. The study cohort consisted of 3,276 individuals from the greater Stockholm area, Sweden. Of them, 1,655 were clinically examined at baseline. Patients were followed-up for >35 years, using the national population and patient registers. The burden of systemic diseases and purchases of medicines were statistically analyzed comparing patients with (n = 285) and without (n = 1,370) periodontitis. The results showed that patients with periodontitis had purchased more of certain medications than non-periodontitis patients. Periodontitis patients purchased significantly more drugs used in diabetes (p = 0.035), calcium channel blockers (...

The study hypothesis was based on the oral inflammation vs. systemic health paradigm. A sample of 2,168 subjects from an original cohort of 105,718 individuals from the greater Stockholm area in Sweden that had been followed since 1985 was investigated. Swedish national health registers were used in the study. Chi-square tests and logistic multiple regression analyses were conducted. The results showed that periodontitis was significantly associated with any cancer after adjusting for gender, age, income, and education (p = 0.015). The probability of getting cancer increased on average by 38% if the patient had periodontitis vs. had not; the odds ratio was 1.380 (95% confidence interval l.066-1.786). No significant association was observed between periodontitis and breast cancer (p =...

Various preventive strategies have been proposed and included in national health programs promoting oral health. Interest in probiotics in light of oral health has gradually evolved as attractive means in prevention of oral infectious diseases. The aim of the present review is to outline the current evidence on the role of probiotic species on oral health parameters and their benefi cial role in contributing to healthier oral environment.

OBJECTIVE: We hypothesized that certain periodontal microorganisms might specifically link to malignancies in general and set out to investigate this in our ongoing cohort study. METHODS: A sample of 99 clinically examined patients from our cohort of 1676 subjects was used to statistically investigate the associations between harboring periodontal microorganisms Aggregatibacter actinomycetemcomitans (A.a), Porphyromonas gingivalis (P.g), Prevotella intermedia (P.i), Tannerella forsythia (T.f) and Treponema denticola (T.d). We used oral infection indexes and the incidence figures of malignancies as registered in 2008–2016 in the Swedish National Cancer Register. RESULTS: The pathogen A.a showed strong association with malignancy in 32 out of the 99 patients while P.g and P.i were more prevalent among patients without malignancy. In principal component analyses, A.a appeared in the strongest component while the second st...

Its consumption is increasing in many industrialized countries due to effective marketing. Wine may also have effects in the oral cavity mainly due to its acidity and alcohol content. This article briefly describes some effects of wine, both beneficial and detrimental, on oral and general health. In particular, the effect of wine on tooth enamel is demonstrated.

Yet, coronary atherosclerosis has been suggested to be an inflammatory disease in which chronic dental infections may trigger pathogenic mechanisms in the walls of arteries. In epidemiological studies periodontal disease in particular has been linked with coronary heart disease (CHD). We set out to investigate by means of clinical examination, x-ray, and questionnaire the oral health status, health-related behavior, and conceptions of 256 CHD patients referred for open-heart surgery in the Kuopio University Hospital. The patients' heart disease was New York Heart Association grades II-IV. For comparison, 250 age- and sex-matched non-CHD patients were also studied. Differences between groups were analyzed conventionally and with the Total Dental Index (TDI), which uses linear modeling and logistic regression analyses to summarize periodontal factors and other signs of oral infections. We expected to find neglected dental care and worse oral health situation among the CHD patients. Edentulousness was seen in 35% of the CHD group and in 15% of the non-CHD group (P < .001). The CHD group had significantly lower number of teeth (8.8 +/- 9.1) than the non-CHD group (17 +/- 10.5; P < .001). No dental appointment in the past 10 years was reported in 66% of the CHD patients and 35% of the non-CHD patients. Forty-nine percent of the CHD group and 69% of the non-CHD group had had a dental visit within the past 2 years (P < .001). Daily tooth brushing was reported by 46% of the CHD group and 56% of the non-CHD group (P < .05). Only 2% of the CHD group and 8% of the non-CHD group flossed daily (P < .001). TDI scores were significantly higher in the edentulous than in the dentate study groups (P < .001), but no difference was observed between CHD and non-CHD patients of the same dentate or edentulous status. Mean TDI score was 3.2 +/- 0.8 in edentulous CHD patients and 3.1 +/- 0.4 in edentulous non-CHD patients; the scores in the dentate patients were 2.5 +/- 0.9 in the CHD group and 2.4 +/- 2.0 in the non-CHD group. The TDI score appeared almost significant a predictor of CHD when used as a dependent variable in logistic regression analysis (P = .08). Worse oral health status and less satisfactory oral health behavior were observed in the CHD patients than among the cardiologically healthy.

We expected to find the studied symptoms more frequently in the frail elderly than in those who were healthier. We examined 175 home-living elderly patients (mean age with SD, 82 +/- 5.7 years) hospitalized because of sudden worsening of their general health. For comparison, 252 elderly outpatients (mean age with SD, 77 +/- 5.7 years) from the same community were studied. The subjects' medical diagnoses and prescribed drugs used daily were recorded, their oral health examined, and saliva samples taken for analyses of flow rates, yeasts, and a variety of biochemical factors. The results showed that 63% of the hospitalized patients and 57% of the outpatients complained of dry mouth. The respective percentages of burning mouth were 13% in the hospitalized and 18% in the outpatients. The dentate status affected the feeling of dry mouth and burning mouth, but there were no consequent differences in concentrations of salivary biochemical constituents, yeast counts, and buffering capacity between patients with or without the symptoms except that hospitalized patients complaining of dry mouth more often had low salivary buffering than those without the symptom. Dry mouth was also more prevalent among the hospitalized patients who used several drugs daily, whereas no such association was found with the burning-mouth symptom. Use of analgesics appeared to safeguard against both the symptoms. Dry mouth and burning mouth were seldom reported simultaneously, although low salivary flow rate was a common finding in patients with burning mouth. The strongest explanatory factors for burning mouth were psychiatric disease among the outpatients (OR 8.7, CI 1.4-54.1, P <.05) and use of psychiatric drugs among the hospitalized (OR 4.2, CI 0.9-20.0, P =.07). For dry mouth, the strongest explanatory factors were respiratory disease in the outpatients (OR 2.0, CI 1.0-3.8, P <.05) and low salivary flow rate in the hospitalized elderly (OR 3.7, CI 1.4-10, P <.05). In all patients (n = 427), use of psychiatric drugs was the strongest explanatory factor for dry mouth (OR 2.1, CI 1.2-3.5, P <.01), whereas analgesic medication was found to protect against burning mouth (OR 0.5, CI 0.3-0.9, P <.05). The subjective feelings of dry mouth and burning mouth appeared to be a complex issue among the elderly population studied. The 2 symptoms were seldom reported at the same time. The appearance of symptoms did not directly correlate with general health, except in the case of psychiatric diseases and medications, which should be taken into account.

We expected higher albumin values in the frail and diseased elderly in comparison to the more fit elderly. This was thought to be due to the eventually decreased mucosal integrity in the diseased patients. Paraffin wax-stimulated saliva was collected for 5 minutes from 131 hospitalized elderly, mean age of 82 years, and 252 elderly outpatients, mean age of 77 years. Forty-seven of the hospitalized elderly died during the 2-year follow-up. Albumin was analyzed spectrophotometrically from the saliva specimens, and values were studied statistically between the groups and regarding a number of background variables. The following mean salivary albumin concentrations were observed: outpatients, 200 +/- 157 microg/mL; hospitalized surviving patients, 401 +/- 247 microg/mL; patients who later died, 501 +/- 417 microg/mL. The respective albumin output values were 439.7 +/- 432.8 microg/min in outpatients, 684.3 +/- 396.8 microg/min in hospitalized patients who survived, and 700.0 +/- 481.9 microg/min in the hospitalized patients who died. The differences were significant between the groups. The strongest explanatory factors for higher than median albumin concentrations were the use of analgesics in the hospitalized patients (odds ratio, 4.2; confidence interval, 1.5 to 11.4) and retaining own teeth in the outpatients (odds ratio, 4.3; confidence interval, 1.9 to 4.3). Frequency of mucosal pathologic condition did not appear as an explanatory factor in this respect. Our study hypothesis was confirmed, showing significantly higher salivary albumin concentrations in the frail elderly. The present results may also be used as reference data for salivary albumin in the elderly.

Fifteen radiolabeled dairy L. delbrueckii subsp. bulgaricus strains and L. rhamnosus GG were tested for their ability to adhere to saliva-coated hydroxyapatite beads and polystyrene microtiter plates and the radioactivity was measured by liquid scintillation counter. The effects of lysozyme on the adhesion of lactobacilli and of pretreatment with lactobacilli on the adhesion of Streptococcus sanguinis were also assessed. All strains tested adhered to saliva-coated surfaces but with significantly different binding frequencies. The adhesion of the L. delbrueckii subsp. bulgaricus strains remained lower in comparison to L. rhamnosus strain GG. One L. delbrueckii subsp. bulgaricus strain showed binding frequency comparable to S. sanguinis. Lysozyme pretreatment of the samples significantly increased lactobacillus adhesion to saliva-coated surfaces. The present results showed significant variations in the adhesion capacity of the Lactobacillus strains studied. Adhesion to oral surfaces is of primary importance for bacterial colonization in the mouth. Only one of the L. delbrueckii subsp. bulgaricus dairy starter culture strains investigated had a high adhesion percentage. This strain might then be considered for further investigations in the oral environment.

Increased bacterial load in lungs is known to be a risk factor for decline in forced expiratory volume during the first second. The aim was to evaluate both cross-sectionally and longitudinally the association between oral health status and forced expiratory volume during the first second (FEV1) in older residents of the city of Jyväskylä, Finland. Cross-sectional and prospective cohort study over a 5-year follow-up. Research laboratory of the University of Jyväskylä. In 1990 dental status and FEV1 were examined in 203 80-year-old people, of whom 88 survivors were retested 5 years later. Primary: dental status and FEV1. Secondary: existence of pulmonary diseases, height, handgrip strength, smoking, and length of education. Participants were regrouped into three categories according to their baseline oral health status. At baseline, men with complete prostheses had the lowest FEV1. Five years later the greatest reduction in FEV1 was seen in subjects with poor periodontal status or complete prostheses (-9.4%) while those with healthy periodontal status showed no reduction in FEV1 values (+1.0%, p = 0.006). Periodontal infections and complete prostheses may be reservoirs for pathogens which may be harmful and partly explain the observed reduction in FEV1 during ageing.

Cross-sectional and prospective cohort study over a 5-year follow-up. Research laboratory of the University of Jyväskylä. In 1990 dental status and FEV1 were examined in 203 80-year-old people, of whom 88 survivors were retested 5 years later. Primary: dental status and FEV1. Secondary: existence of pulmonary diseases, height, handgrip strength, smoking, and length of education. Participants were regrouped into three categories according to their baseline oral health status. At baseline, men with complete prostheses had the lowest FEV1. Five years later the greatest reduction in FEV1 was seen in subjects with poor periodontal status or complete prostheses (-9.4%) while those with healthy periodontal status showed no reduction in FEV1 values (+1.0%, p = 0.006). Periodontal infections and complete prostheses may be reservoirs for pathogens which may be harmful and partly explain the observed reduction in FEV1 during ageing.
