A ligature-induced periodontitis model employing the beagle dog was used to study the levels of aspartate aminotransferase (AST) in crevicular fluid before and after ligation. A significant increase in AST level occurred in crevicular fluid 2 weeks after ligation whereas no increase of enzyme was found in serum. Enzyme levels in crevicular fluid were 10- to 100-fold higher than in serum. Dental plaque did not appear to be the source of the enzyme. Since aspartate aminotransferase has been documented as a marker of cellular injury arising during heart disease and liver disease, this study suggests that aspartate aminotransferase, in like fashion, reflects cellular damage arising from active periodontal disease.

A retrospective study was conducted at the University of Alabama in Birmingham Medical Center on patients diagnosed as having BE from the years 1969 to 1979, with emphasis on dental involvement. A major finding of this report revealed that 16 percent of the cases of BE had a history of recent dental care or pathology. Other results of this investigation included the following: (1) Streptococcus viridans was the predominant microorganism associated with BE; (2) the mortality rate relative to predisposing heart disease was highest for patients with prosthetic heart valves; (3) chronic valvular heart disease was the heart problem most susceptible to BE; (4) chronically abscessed teeth and periodontal disease may be initiating factors of BE.

Many individuals with cardiovascular disease appear from epidemiologic studies to have either periodontal disease or to be edentulous. A Finnish group has provided evidence that after conventional risk factors for stroke and heart attacks have been accounted for, there still remains a significant relationship between dental disease and cardiovascular disease. A preliminary analysis of our own investigation of the interrelationship of medical and dental health shows that individuals with a high dental morbidity (ie, edentulous or with many missing teeth) have a high prevalence of coronary heart disease and stroke. A model based on how smoking can predispose to periodontal disease is used to explain how periodontal disease could be a potential risk factor for heart disease.

Infective endocarditis represents one of the few potentially fatal infections that may be caused in the patient by a dentist. Efforts to reduce the incidence of this disease usually take the form of appropriate antibiotic cover prior to dental treatment, together with the establishment and maintenance of good oral health. This paper is a report of a survey on the dental health and awareness of 81 'at-risk' patients attending a cardiology outpatient clinic. It was found that whilst the patients were apparently well motivated and well informed, a high prevalence of periodontal disease existed in the group. It is concluded that when patients are diagnosed with a cardiac disorder which predisposes to infective endocarditis they should have a dental examination as soon as possible, preferably by a dentist experienced in the treatment of patients with special needs.

The detailed mortality and morbidity statistics on smoking tend to conceal the overall impact of the habit on health. About 3 million people die each year from smoking in economically developed countries, half of them before the age of 70. Cancers of eight sites are recognized as being caused by smoking--lung cancer almost entirely and the others (upper respiratory, bladder, pancreas, oesophagus, stomach, kidney, leukaemia) to a substantial extent. Six other potentially fatal diseases are also judged to be caused by smoking: respiratory heart disease, chronic obstructive lung disease, stroke, pneumonia, aortic aneurysm and ischaemic heart disease, the most common cause of death in economically developed countries. Non-fatal diseases, such as peripheral vascular disease, cataracts, hip fracture, and periodontal disease, which cause appreciable disability, cost and inconvenience are also caused by smoking. In pregnancy, smoking increases the risk of limb reduction defects, spontaneous abortion, ectopic pregnancy, and low birth weight. While there are some diseases for which smoking shows a protective effect, the 'benefits' of these are negligible in relation to the illness and premature mortality caused by smoking. About 20% of all deaths in developed countries are caused by smoking; an enormous human cost which can be completely avoided.

The number of Americans with diabetes mellitus has increased 50% since 1983 to 16 million. An interesting and startling factor is that only half of these diabetics are aware they have the disease. Diabetes mellitus can lead to blindness, heart disease, stroke, nerve damage, kidney failure, and periodontal disease. It is the fourth leading cause of death in the United States. A metabolic disorder affecting insulin metabolism and associated blood glucose intolerance regulation, diabetes may be classified by the following categories: type I-insulin dependent diabetes mellitus which is commonly found in children and adolescents and type II-non-insulin-dependent or adult-onset diabetes which occurs in patients over forty and is associated with obesity. The dental hygienist's role in education, prevention, and therapeutics has expanded to detection and recognition of oral manifestations of diabetes. The dental hygienist may be the first to recognize the presence of the disease. This article aims to acquaint the dental hygienist with the clinical picture of a dental patient with diabetes mellitus.

(The role that oral conditions may play as risk factors or indicators for various medical outcomes, including mortality, is not well understood. We have examined the relationship of periodontal disease to mortality from all causes in the VA Dental Longitudinal Study and Normative Aging Study, a prospective cohort study of the determinants of disease in aging men. Subjects were screened for entry into the closed-panel cohort in the mid-1960s, based on good medical health. They are not VA patients. We have used proportional hazards regression models to assess the relationship of periodontal health status at baseline to all-cause mortality over a 25+-year follow-up period. A total of 804 dentate subjects who were alive and medically healthy through their first follow-up exam were used in the analysis; of these, 166 died during subsequent follow-up through December 1996. Survival was calculated in years from baseline exam to death or censoring (most recent study examination date). To define periodontal health status at baseline, we separately used radiographic alveolar bone loss (ABL) (person-level scores of mean whole-mouth % ABL, measured with a Schei ruler using full-mouth series of periapical films) and periodontal clinical probing depths. Covariates included age at baseline, and assessments at baseline of smoking and alcohol use, education, body mass index, serum cholesterol, white blood cell count, blood pressure, family history of heart disease, and number of teeth present. We found that periodontal status at baseline was a significant and independent predictor of mortality in this cohort, while controlling for other recognized predictors in multivariate models. For each 20% increment in mean whole-mouth ABL, the subject's risk of death increased by 51% (RR = 1.51; 95% CI = 1.11-2.04). The increase in risk attributable to periodontal status was found to be similar in magnitude to, and independent of that attributable to cigarette smoking in this cohort. While the increased risk due to smoking was 1.52-fold (95% CI = 1.06-2.19), being in the population quintile with highest ABL scores (i.e., worst periodontal status) was associated with a 1.85 fold increase in risk (95% CI = 1.25-2.74) using multivariate analyses. The hypothesis that chronic oral infections, as in periodontitis, may have important systemic sequelae merits further investigation in prospective controlled studies.

Recent studies in periodontal medicine suggest a mild to moderate association between human periodontal disease and certain systemic disorders such as diabetes mellitus, pneumonia, heart disease and preterm birth. The latest evidence, presented at a symposium entitled Periodontal Health and Systemic Disorders, sponsored by the University of Western Ontario School of Dentistry, showed that indeed such an association is likely. New data suggest that this association is not indicated by traditional clinical signs of periodontal disease but rather by a cluster of host immune and inflammatory mediators. The coming era of periodontal medicine based upon molecular criteria will affect the future of periodontal diagnosis, treatment and professional practice.

Microorganisms harbored in the oral cavity have long been recognized to cause systemic disease with a well known mechanism of spread via the blood stream. Different factors, including the presence of periodontal disease, the number of dental extractions or the duration of dental surgery have an influence on the risk of bacteremia. Infectious endocarditis is classically cited, but there are other potential problems including brain abscess, meningitis, lung or lie abscess, and even for some authors, a risk of thrombotic heart disease. It is important to keep in mind that some of these focal infections may be possible complications of dental (or buccal) infection. Prevention is crucial.

OBJECTIVE: Recently, it has been suggested that periodontal disease during pregnancy could have a causal relationship with low weight at birth. Our objective was to evaluate the influence of periodontal disease during pregnancy on the birth weight of newborn infants. METHODS: Mothers who gave birth to low-birth-weight infants were randomly selected (Group 1 - G1; n=13). Immediately after inclusion of each mother in group 1, the mother of the next term newborn with birth weight of > 2,500 g (Group 2 - G2; n=13) was included as control. Mothers were examined by a periodontist who was not informed of the group the child belonged to. A probe was used to measure attachment loss of the alveolar bone. The extension index (EI) and severity index (SI) of the periodontal disease were determined. RESULTS: Both groups of mothers were similar in terms of maternal age, parity, color of skin, height, nutrition, smoking, drinking, socioeconomic status, prenatal examinations, premature rupture of membranes, chorioamnionitis, bacteriuria, placenta previa, abruptio placentae, previous hypertensive disease, preeclampsia, and heart disease. The characteristics of the newborns were: birth weight - G1 = 1,804 -/+ 675 g x G2 = 3,030 -/+ 516 g; gestational age - G1 = 33 -/+ 5 weeks x G2 = 39 -/+ 2 weeks; length of stay in the neonatal intensive care unit (NICU) - G1 = 128 days x G2 = 0 days. Average EI: G1 = 89.788 -/+ 18.355 x G2 = 72.420 -/+ 20.717; p=0.033. Average SI: G1 = 1.377 -/+ 0.626 x G2 = 0.754 -/+ 0.413 (OR=18.3; CI95%: 2.5-133.3; p = 0.006). After adjustment for risk factors for low birth weight, such as smoking, maternal height, bacteriuria, and previous hypertension, the odds ratio for SI dropped to 7.2 (CI95% = 0.4-125.4; P = 0.176). CONCLUSION: The multivariate analysis indicated a marked association between periodontal disease measured by SI score and low birth weight. Our data suggested that periodontal disease during pregnancy may be a risk factor for low weight at birth.
