The effect of a degradable controlled release system containing cetylpyridinium chloride (CPC) on plaque accumulation and gingivitis was evaluated when applied on the anterior teeth of volunteers (16-17 years) over 4 weeks. At baseline, plaque index (PI) and gingival index (GI) of the Ramfjord teeth were measured in the experimental and placebo groups, including 23 and 21 participants respectively. Following scaling and root planning, the participants were instructed to brush, using one brush stroke, the film-forming solution on the buccal surface of the maxillary and mandibular incisors, 1 x a day before bedtime. The applied active solution contained 9 mg of CPC (approximately 80 mg of 11% CPC solution), while the placebo solution was identical in formation, but without the active agent. After 4 weeks, in the CPC-applied group, the recorded PI scores were 0.52 (+/- 0.56) in the anterior area and 1.31 (+/- 0.80) in the posterior area, whereas the corresponding areas in the placebo group reached 1.25 (+/- 0.74) and 1.51 (+/- 1.00), respectively. The PI = 0 frequency in the buccal anterior surfaces after 4 weeks was 54.6% (+/- 38.7%) in the experimental group as compared with 21.9% (+/- 29.0%) in the placebo group (p = 0.005). In contrast to the anterior teeth, there was no significant difference between groups with respect to the PI scores in the non-applied posterior teeth. It may be postulated that the impressive 58% inhibition of plaque accumulation at the site of application is the result of an increase of the substantivity of the CPC due to its incorporation in the film-forming degradable controlled release system.

The aim of this study was to define a population of diabetics exhibiting an increased risk of developing severe periodontitis by comparing the medical status of 2 groups of diabetics, 1 with no/minor periodontal disease and 1 with severe periodontal disease. The case-control study consisted of 2 parts, a baseline study and a follow-up study. 39 case-control pairs were selected. They were adult, long-duration, insulin-dependent diabetics matched according to sex, age and diabetes duration. One individual in each pair (the CASE) exhibited severe periodontal disease while the other (the CONTROL) exhibited gingivitis or only minor alveolar bone loss. The median age of the cases was 58 years (range 36 to 70 years) and of the controls 59 years (range 37 to 69 years). The median disease duration in cases and controls was 24 years and 25 years, respectively. The median follow-up time was 6 years. The medical variables analysed were weight, insulin dose, systolic and diastolic blood pressure, vibratory threshold, triglycerides, total-cholesterol, HDL-cholesterol, creatinine, HbA1, proteinuria, ECG, retinopathy, stroke, transient ischemic attacks (TIA), angina, myocardial infarct, heart failure, hypertension, intermittent claudication, foot ulcer, death, cause of death, and smoking habit. Biochemical analyses and clinical variables used as a routine in the monitoring of diabetics failed to differentiate between diabetics with severe and minor periodontal disease. In the follow-up study, significantly higher prevalences of proteinuria and cardiovascular complications such as stroke, TIA, angina, myocardial infarct and intermittent claudication were found in the case group. An association between renal disease, cardiovascular complications and severe periodontitis seems to exist. This indicates that a closer cooperation between the diabetologist and the dentist is necessary in monitoring the diabetic patient.

The periodontal diseases are highly prevalent and can affect up to 90% of the worldwide population. Gingivitis, the mildest form of periodontal disease, is caused by the bacterial biofilm (dental plaque) that accumulates on teeth adjacent to the gingiva (gums). However, gingivitis does not affect the underlying supporting structures of the teeth and is reversible. Periodontitis results in loss of connective tissue and bone support and is a major cause of tooth loss in adults. In addition to pathogenic microorganisms in the biofilm, genetic and environmental factors, especially tobacco use, contribute to the cause of these diseases. Genetic, dermatological, haematological, granulomatous, immunosuppressive, and neoplastic disorders can also have periodontal manifestations. Common forms of periodontal disease have been associated with adverse pregnancy outcomes, cardiovascular disease, stroke, pulmonary disease, and diabetes, but the causal relations have not been established. Prevention and treatment are aimed at controlling the bacterial biofilm and other risk factors, arresting progressive disease, and restoring lost tooth support.

Oral conditions such as gingivitis and chronic periodontitis are found worldwide and are among the most prevalent microbial diseases of mankind. The cause of these common inflammatory conditions is the complex microbiota found as dental plaque, a complex microbial biofilm. Despite 3000 years of history demonstrating the influence of oral status on general health, it is only in recent decades that the association between periodontal diseases and systemic conditions such as coronary heart disease and stroke, and a higher risk of preterm low birth-weight babies, has been realised. Similarly, recognition of the threats posed by periodontal diseases to individuals with chronic diseases such as diabetes, respiratory diseases and osteoporosis is relatively recent. Despite these epidemiological associations, the mechanisms for the various relationships remain unknown. Nevertheless, a number of hypotheses have been postulated, including common susceptibility, systemic inflammation with increased circulating cytokines and mediators, direct infection and cross-reactivity or molecular mimicry between bacterial antigens and self-antigens. With respect to the latter, cross-reactive antibodies and T-cells between self heat-shock proteins (HSPs) and Porphyromonas gingivalis GroEL have been demonstrated in the peripheral blood of patients with atherosclerosis as well as in the atherosclerotic plaques themselves. In addition, P. gingivalis infection has been shown to enhance the development and progression of atherosclerosis in apoE-deficient mice. From these data, it is clear that oral infection may represent a significant risk-factor for systemic diseases, and hence the control of oral disease is essential in the prevention and management of these systemic conditions.

Oral care is essential to maintain oral health and prevent complications such as tooth loss, gingivitis and periodontitis. Poor oral hygiene in dependent, hospitalised patients could lead to serious complications such as chest infection, pneumonia, poor nutritional intake and increased length of hospital stay. Patients who have had a stroke may have physical and cognitive problems that make them dependent on others for their personal care, including oral care. It is essential that nurses and carers understand why maintaining oral hygiene is important following stroke and the consequences of poor oral care.

The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger is an important kitchen spice and also possess a myriad health benefits. The rhizomes have been used since antiquity in the various traditional systems of medicine to treat arthritis, rheumatism, sprains, muscular aches, pains, sore throats, cramps, hypertension, dementia, fever, infectious diseases, catarrh, nervous diseases, gingivitis, toothache, asthma, stroke and diabetes. Ginger is also used as home remedy and is of immense value in treating various gastric ailments like constipation, dyspepsia, belching, bloating, gastritis, epigastric discomfort, gastric ulcerations, indigestion, nausea and vomiting and scientific studies have validated the ethnomedicinal uses. Ginger is also shown to be effective in preventing gastric ulcers induced by nonsteroidal anti-inflammatory drugs [NSAIDs like indomethacin, aspirin], reserpine, ethanol, stress (hypothermic and swimming), acetic acid and Helicobacter pylori-induced gastric ulcerations in laboratory animals. Various preclinical and clinical studies have also shown ginger to possess anti-emetic effects against different emetogenic stimuli. However, conflicting reports especially in the prevention of chemotherapy-induced nausea and vomiting and motion sickness prevent us from drawing any firm conclusion on its effectiveness as a broad spectrum anti-emetic. Ginger has been shown to possess free radical scavenging, antioxidant; inhibition of lipid peroxidation and that these properties might have contributed to the observed gastroprotective effects. This review summarizes the various gastroprotective effects of ginger and also emphasizes on aspects that warranty future research to establish its activity and utility as a gastroprotective agent in humans.

This review aimed to determine the association between periodontal disease and stroke incidence by a meta-analysis of cohort studies. Cohort studies that evaluated the incidence of stroke (fatal or non-fatal, ischaemic or haemorrhagic) and baseline periodontal status and calculated relative risk values were included. The quality of the included studies was assessed using an evaluation grid. The analyses were conducted separately for three outcomes: periodontitis, gingivitis and loss of teeth. Adjusted values of relative risk or of hazard ratio were used to assess risk values in each study. Random effects meta-analyses were conducted when data could be pooled. From the 743 references retrieved, only nine cohort studies were suitable for inclusion in this review. Quality scores of the studies varied greatly. Three prospective studies, which used reliable indicators of periodontal disease, obtained the highest scores. Conversely, three studies that used a subjective evaluation of stroke incidence or diagnosed stroke without imaging obtained the lowest score. The results of the meta-analyses varied depending on the outcome considered and the type of stroke. The risk of stroke was significantly increased by the presence of periodontitis [relative risk 1.63 (1.25, 2.00)]. Tooth loss was also a risk factor for stroke [relative risk 1.39 (1.13, 1.65)]. The risk of stroke did not vary significantly with the presence of gingivitis. This review shows that periodontitis and tooth loss are associated with the occurrence of stroke.

The use of intravenous thrombolytic therapy (ITT) in acute ischemic stroke (AIS) patients is still debated in China. We present the analysis of clinico-demographic retrospective data of 646 AIS patients that were treated by alteplase ITT at our hospital. The data collected included age, gender, education, income, drug use before disease onset, and awareness of stroke/ITT. The risk factors studied were hypertension, diabetes, hyperlipidemia, atrial fibrillation, coronary heart disease, cerebral infarction, transient ischemic attack, valvular heart disease, thyroid disease, migraine, asymptomatic carotid stenosis, family history of stroke, hyperhomocysteinemia, smoking, drinking, and gingivitis. Pre-ITT patient data included blood pressure and time from onset to hospital. Post-ITT patient data included National Institutes of Health Stroke Scale (NIHSS) scores, clinical outcome, revascularization, hemorrhage, healing rate, and 90-day mortality. Hospital management information included monthly ITT cases, discharges, bed turnaround times, length of hospital stay, bed utilization, drug ratio, massive cerebral infarction decompressive craniectomy, and social impact. Prognosis evaluation was based on post-ITT NIHSS and modified Rankin Scale (mRS) scores. We found that ITT success rate was 75.85 %, with a bleeding rate of 1.55 % and a 90-day mortality rate of 2.01 %. Overall, the data suggest that the ITT therapy was highly successful in AIS patients treated at our hospital.

Orofacial pain' most commonly occurs due to dental causes like caries, gingivitis or periodontitis. Other common causes of 'orofacial pain' are sinusitis, temporomandibular joint(TMJ) dysfunction, otitis externa, tension headache and migraine. In some patients, the etiology of 'orofacial pain' remains undetected despite optimal evaluation. A few patients in the practice of clinical dentistry presents with dental pain without any identifiable dental etiology. Such patients are classified under the category of 'atypical odontalgia'. 'Atypical odontalgia' is reported to be prevalent in 2.1% of the individuals. 'Atypical orofacial pain' and 'atypical odontalgia' can result from the neurological diseases like multiple sclerosis, trigeminal neuralgia and herpes infection. Trigeminal neuralgia has been frequently documented as a cause of 'atypical orofacial pain' and 'atypical odontalgia'. There are a few isolated case reports of acute pontine stroke resulting in 'atypical orofacial pain' and 'atypical odontalgia'. However, pontine stroke as a cause of atypical odontalgia is limited to only a few cases, hence prevalence is not established. This case is one, where a patient presented with acute onset atypical dental pain with no identifiable dental etiology, further diagnosed as an acute pontine infarct on neuroimaging. A 40 years old male presented with acute onset, diffuse teeth pain on right side. Dental examination was normal. Magnetic resonance imaging(MRI) of the brain had an acute infarct in right pons near the trigeminal root entry zone(REZ). Pontine infarct presenting with dental pain as a manifestation of trigeminal neuropathy, has rarely been reported previously. This stresses on the importance of neuroradiology in evaluation of atypical cases of dental pain.

Infectious pathogens from the oral cavity cause oral diseases such as caries, gingivitis, periodontitis, endodontic infections, and alveolar osteitis, and often are also concomitant to systemic diseases, including cardiovascular disorders, stroke, preterm birth, diabetes, and pneumonia, among others. The relationship(s) between oral infections and systemic diseases are still unclear. Using the bacterial cell surface antigen I/II from S. mutans and cardiovascular diseases as a model, this study analyzes peptide commonalities that might underlie autoimmune crossreactions between the bacterial antigen and human proteins associated with cardiovascular disorders. The study outlines a vast peptide sharing that calls attention on autoimmune crossreactivity as a possible mechanism by which S. mutans infection might contribute to induce cardiovascular diseases, and, more in general, offers a new approach to investigate the still elusive molecular links between focal oral infections and human systemic diseases.
