The true incidence of neuropathic pain is unknown, but it is believed to be under-diagnosed and treated inadequately, despite the availability of drugs with proven efficacy. Our objective was to report the epidemiology and drug treatment of neuropathic pain as managed by UK primary care physicians. A descriptive analysis of the epidemiology of incident post-herpetic neuralgia (n=12,386); trigeminal neuralgia (8268); phantom limb pain (451) and painful diabetic neuropathy (4719) and prescription treatment at diagnosis from computerised UK general practice records (GPRD): January 1992 to April 2002. Incidences per 100,000 person years observation of 40 (95% CI 39-41) for post-herpetic neuralgia, 27 (26-27) for trigeminal neuralgia, 1 (1-2) for phantom limb pain and 15 (15-16) for painful diabetic neuropathy are reported, with rates decreasing over time for phantom limb pain and post-herpetic neuralgia and increasing for painful diabetic neuropathy. Drugs were initiated at first diagnosis record for 46-66% of conditions, usually one item, with antidepressants included in 30% of prescriptions, anticonvulsants in 20% and opioid analgesics in 20%. The most commonly prescribed items were the same across conditions; amitriptyline, carbamazepine, coproxamol, codydramol and codeine+paracetamol. Carbamazepine was prescribed to 58% of the trigeminal neuralgia cohort. In 2600 patients followed to stable therapy, there was a median of one to two drug changes. We provide the primary care managed incidence of four neuropathic pain conditions. For commonly prescribed treatments, changes in therapy are less frequent when initial therapy was with antidepressants or anticonvulsants rather than conventional analgesics.

The mouth is a mirror of health or disease, a sentinel or early warning system. The oral cavity might well be thought as a window to the body because oral manifestations accompany many systemic diseases. In many instances, oral involvement precedes the appearance of other symptoms or lesions at other locations. Oral lichen planus (OLP) is a chronic mucocutaneous disorder of stratified squamous epithelium of uncertain etiology that affects oral and genital mucous membranes, skin, nails, and scalp. LP is estimated to affect 0.5% to 2.0% of the general population. This disease has most often been reported in middle-aged patients with 30-60 years of age and is more common in females than in males. The disease seems to be mediated by an antigen-specific mechanism, activating cytotoxic T cells, and non-specific mechanisms like mast cell degranulation and matrix metalloproteinase activation. A proper understanding of the pathogenesis, clinical presentation, diagnosis of the disease becomes important for providing the right treatment. This article discusses the prevalence, etiology, clinical features, oral manifestations, diagnosis, complications and treatment of oral LP.

An ideal dental repair material should possess certain exclusive properties such as adequate adhesive ability, insolubility, dimensional stability, biocompatibility, bioactivity etc. New materials claiming better performance are continuously being introduced in the market to optimize the care of dental patients. Biodentine has been recently introduced as the "the first all-in-one, bioactive and biocompatible material for damaged dentin replacement". Manufacturers claim that Biodentine has noticeably shorter setting time in contrast to other silicate cements such as Mineral Trioxide Aggregate (MTA) and also has better mechanical and handling properties. This article is aimed to compare the properties of MTA and Biodentine analyzing the research work done in this field so far by various researchers all across the globe.

BACKGROUND: Between 1992 and 2001 the UK general practice incidence of post-herpetic neuralgia and trigeminal neuralgia declined, whilst the incidence of painful diabetic neuropathy increased. The most common first line treatments were compound analgesics. As therapeutic options have subsequently changed, this study presents updated data on incidence and prescribing patterns in neuropathic pain. METHODS: A descriptive analysis of the epidemiology and prescription treatment at diagnosis of incident post-herpetic neuralgia (n = 1,923); trigeminal neuralgia (1,862); phantom limb pain (57) and painful diabetic neuropathy (1,444) using computerised UK general practice records (THIN): May 2002 to July 2005. RESULTS: Primary care incidences per 100,000 person years observation of 28 (95% confidence interval (CI) 27-30) for post-herpetic neuralgia, 27 (95%CI 26-29) for trigeminal neuralgia, 0.8 (95%CI 0.6-1.1) for phantom limb pain and 21 (95%CI 20-22) for painful diabetic neuropathy are reported. The most common initial treatments were tricyclic antidepressants (post-herpetic neuralgia) or antiepileptics (trigeminal neuralgia and painful diabetic neuropathy) and opioid analgesics (phantom limb pain). The mean number of changes before a stable drug regimen was 1.2 to 1.5 for trigeminal neuralgia, painful diabetic neuropathy and post-herpetic neuralgia, and 2.4 for phantom limb pain. CONCLUSION: The incidence of phantom limb pain and post-herpetic neuralgia are decreasing whilst painful diabetic neuropathy plateaued and trigeminal neuralgia remained constant. Despite more frequent use of antidepressants and antiepileptics for first line treatment, as opposed to conventional non-opioid analgesics, changes to therapy are common before a stable regimen is reached.

Diabetes mellitus is a noncommunicable disease with a rising prevalence worldwide and in developing countries. The most commonly used diagnostic biofluid for detection of glucose levels is blood, but sample collection is an invasive and painful procedure. Thus, there arises a need for a noninvasive and painless technique to detect glucose levels. The objectives of the present study were to estimate the glucose levels of saliva, to assess if any significant correlation existed between the serum and salivary glucose levels, and to correlate salivary glucose levels with regard to duration of diabetes, age, and gender. In the present study, serum and salivary glucose levels of 200 subjects (100 diabetic subjects and 100 nondiabetic subjects) were estimated by glucose oxidase method. Glycosylated hemoglobin levels were also measured in randomly selected 40 diabetic subjects. The findings of present study revealed a significant correlation between salivary and serum glucose levels in both diabetic and nondiabetic subjects. No significant relationship was observed between salivary glucose levels and gender or age in both diabetics and nondiabetics and between salivary glucose levels and duration of diabetes in diabetics. On the basis of the findings, it was concluded that salivary glucose levels could serve as a potentially noninvasive adjunct to monitor glycemic control in diabetic patients.

Oral health has a significant impact on the quality of life, appearance, and self-esteem of the people. Preventive dental visits help in the early detection and treatment of oral diseases. Dental care utilization can be defined as the percentage of the population who access dental services over a specified period of time. There are reports that dental patients only visit the dentist when in pain and never bother to return for follow-up in most cases. To improve oral health outcomes an adequate knowledge of the way the individuals use health services and the factors predictive of this behavior is essential. The interest in developing models explaining the utilization of dental services has increased; issues like dental anxiety, price, income, the distance a person had to travel to get care, and preference for preservation of teeth are treated as barriers in regular dental care. Published materials which pertain to the use of dental services by Indian population have been reviewed and analyzed in depth in the present study. Dental surgeons and dental health workers have to play an adequate role in facilitating public enlightenment that people may appreciate the need for regular dental care and make adequate and proper use of the available dental care facilities.

The conventional formulation of prednisolone is considered to be low in efficacy, primarily on account of their failure in providing and maintaining effective therapeutic drug levels. This study aims to focus on development of a mucoadhesive buccal delivery system with a twofold objective of offering a rapid as well as a prolonged delivery of prednisolone coupled with enhanced therapeutic efficacy. Buccoadhesive films of prednisolone were prepared by solvent-casting method using hydroxyl propyl methyl cellulose (K100), Carbopol 940 and/or Eudragit NE 40 D. Placebo films possessing the most desirable physicomechanical properties were selected for drug loading. The effect of polymer and its content on film properties, i.e. mucoadhesive strength, swelling and hydration, in vitro drug release was studied. Based on these studies, film F7D was selected for ex vivo permeation across porcine cheek mucosa. The steady state flux of prednisolone across the buccal mucosa was found to be 105.33 ± 32.07 µg/cm(2)/h. A comparative pharmacokinetic study of prepared film (F7D) and oral suspension of prednisolone was conducted. In vivo data of buccal film show greater bioavailability (AUC0-α: 24.26 ± 4.06 µg.h/ml versus 10.65 ± 2.15 µg.h/ml) and higher Cmax (2.70 ± 0.38 µg/ml versus 2.29 ± 0.32 µg/ml) value when compared to oral suspension. The data observed from this study highlight the feasibility of the buccal route as a viable option for delivery of prednisolone.

The use of dental implants for the rehabilitation of missing teeth has broadened the treatment options for patients and clinicians equally. As a result of advances in research in implant design, materials, and techniques, the use of dental implants has increased dramatically in the past two decades and is expected to expand further in the future. Success of dental implants depends largely on the quality and quantity of the available bone in the recipient site. This however may be compromised or unavailable due to tumor, trauma, periodontal disease, etc., which in turn necessitates the need for additional bone manipulation. This review outlines the various bone manipulation techniques that are used to achieve a predictable long-term success of dental implants.

PURPOSE: Data from a cohort study were used to investigate death and cause of death (COD) recording on the THIN UK primary care database. METHODS: Subjects from 118 practices had a body mass index recorded, 2002-2003 (index date), no recent pregnancy or emotional event, or cancer. Coded and free text entries were searched for a COD for deaths dated < or = 485 days after index date. External documents were requested when date or COD were unclear, suicide was possible, and for a random sample of 40 patients with a COD identified. RESULTS: Five of 1399 deaths dated within 1 year of the index date had not died (positive predictive value 99.6%) and 4 of 222 dated within 366-485 days had died during the year (sensitivity 99.7%). A database COD was identified for 887 (63.4%) with external documents received for 597 (92.8% requested). Of 40 compared with external sources, the underlying COD was on the database in 33 (82.5%), and could be identified as such in 26 (65%). The date was within 1 day of that on external documents in 504 (94.9%) with a date of death but 3 (5.7%) with only a transfer-out of practice date. One of seven suicides was recorded as such. CONCLUSION: Any database record of death or its date is reliable, but transfer-out date is often later. Studies of COD or acute, potentially fatal conditions will miss cases unless a COD is obtained for all fatalities. Most suicides are not noted as such on the electronic record.

Pregnancy is a unique period during a woman's life and is characterized by complex physiological changes, which may adversely affect oral health. The present systematic review was conducted to assess knowledge and awareness regarding oral health among pregnant women in India. Relevant cross-sectional observational studies were included in the systematic review to assess the level of knowledge and awareness regarding oral health among pregnant women in India. Seven studies out of 255 were finally included in the present review after conducting both electronic and manual search of scientific databases. Potential biases were reported and appropriate data were extracted by the concerned investigators. Almost 67% of the subjects had good knowledge and awareness regarding oral health in one of the study findings. Knowledge regarding effect of decayed teeth on the appearance of the people was significantly related to the parity status of the subjects (P = 0.024) in other study reports. Very few subjects (17.1% and 37.5%) felt the need for visiting a dentist during pregnancy in two studies. The results of the present review showed that pregnant women had poor knowledge and awareness regarding oral health. Therefore, there is an urgent need for education and motivation of expectant mothers regarding oral health through various health promotion interventions.

Both classic and revised theories of immigrant assimilation suggest that, over time, immigrants exchange their ethnic and cultural behaviours for the practices and norms of the receiving society. Despite a rise in restrictive subnational policies targeting unauthorised immigrants, the immediate legal context of destinations are absent in this logic, leaving the applicability of assimilation theory for newcomers in such localities an open question. Drawing on qualitative interviews and survey evidence, I find that in hostile receiving communities unauthorised Mexican immigrants present the culture of the dominant core population through their public, outer selves as a protective strategy rather than, as assimilation theory would have it, incorporating the dominant culture into their inner selves. To avoid detection, immigrants' presentation of self is a reactive, purposive and strategic process. Yet trying to pass as a non-suspect native may nevertheless have an assimilatory effect, as the unintended consequences of this practical strategy incrementally contribute to adaptation.

OBJECTIVE: The present study was undertaken to determine the prevalence of oral hygiene practices, smoking habits and halitosis among undergraduate dental students and correlating the oral hygiene practices, oral health conditions to the prevalence of self perceived oral malodour. MATERIALS AND METHODS: A self-administered questionnaire was distributed among 277 male and female students. A questionnaire was developed to assess the self-reported perception of oral breath, awareness of bad breath, timing of bad breath, oral hygiene practices, caries and bleeding gums, dryness of the mouth, smoking and tongue coating. RESULTS: The results indicate female students had better oral hygiene practices. Significantly less self-reported oral bad breath (P = 0.007) was found in female dental students (40%) as compared to their male counterparts (58%). It was found that smoking and dryness of mouth had statistically significant correlation with halitosis (P = 0.026, P = 0.001). Presence of other oral conditions such as tongue coating and dental caries and bleeding gums also showed higher prevalence of halitosis in dental students. CONCLUSION: A direct correlation exists between oral hygiene practices and oral health conditions with halitosis. Females exhibited better oral hygiene practices and less prevalence of halitosis as compared to male students.

BACKGROUND: Hepatitis is an inflammatory disease of the liver. In sever cases, it may lead to permanent liver damage including liver cirrhosis or hepato-cellular carcinoma and may ultimately lead to death. Health-care workers (HCWs), due to their regular contact with patients are at a high-risk of acquiring this disease. AIM: The aim of this study was to assess the knowledge and attitude toward hepatitis B and C infection among the health-care interns and correlate the level of awareness to the attitude they behold toward the disease. SUBJECTS AND METHODS: A closed ended questionnaire consisting of questions to evaluate the knowledge regarding hepatitis B and C infection and attitude of the (HCWs/interns) was duly filled by 255 participants including, 100 dental, 100 medical, and 55 nursing interns. Statistical analysis was carried out using the Chi-square test, ANOVA test, post-hoc test and Pearson's correlation. RESULTS: Although most of the interns were aware of the existence of hepatitis B and C infection, the level of awareness regarding the modes of transmission and vaccination was found to be dissatisfactory. Awareness level regarding the infection among nursing interns was statistically significantly lower than the dental and medical interns. A direct positive correlation as found between awareness score and behavior score, which reveals that interns with better awareness level had better attitudes toward the infection and prevention of its transmission. CONCLUSION: There is an urgent need to increase the level and quality of training among HCWs to prevent the spread of hepatitis B virus and hepatitis C virus.

This review discusses the history of monomers used in resin composites, highlights recent and ongoing research reported in the field of dental monomer systems, and future development. The main deficiencies of current resin composites are polymerization shrinkage and insufficient wear resistance under high masticatory forces. The problem has been approached with the synthesis of potentially low-shrinking/nonshrinking resin composites. Monomer systems have been formulated that improve the degree of conversion and mechanical properties.

UNLABELLED: Oral health is fundamental to general health and well being. Schools can provide a supportive environment for promoting oral health. School policies and education on health-related matters are imperative for the attainment of good oral health and control of related risk behaviors. AIM: This study was conducted to assess oral health-related knowledge, attitude, and practices among 12-year-old schoolchildren studying in rural areas of Panchkula, India. The ultimate goal was to implement an oral health-promotion program in this area. MATERIALS AND METHODS: A total of 440 children (216 males and 224 females) from 12 schools were included in this study. All the participants were requested to complete a 13-question closed-ended questionnaire. The statistical significance of any difference between the two genders was determined using the Chi-square test. RESULTS: Only 25% of the participants said that they cleaned their teeth more than once in a day. Thirty-two percent did not clean their teeth daily. Over the preceding 1 year, 45.5% of the childern had had some problem with their teeth and/or gums, but only 35.9% visited the dentist. Among these children, 8.2% used tobacco in some form. Oral health-related knowledge of girls was significantly better than that of boys. CONCLUSION: Based upon the findings of the present study, the knowledge, attitude, and practices of the surveyed children with regard to oral health is poor. Hence, there is a need for regular oral health education of the children, as well as their parents and school teachers.

AbstractWater is a critical resource in the lives of people who both benefit from its use and who are harmed by its misuse and unpredictability (flooding, droughts, salinity, acidity, and degraded quality). Water is a finite and vulnerable resource. Consequently, consumption of polluted water puts lives and livelihoods at risk because water has no substitute. There are many ways in which water intended for human consumption can get polluted. These include wastes from industries like mining and construction, food processing, radioactive wastes from power generating industries, domestic and agricultural wastes and by various microbiological agents. Nowadays, water is being purified by various methods but research is being conducted to look for more reliable and cheaper methods that can purify water at an affordable cost. Various techniques have been developed like utilizing rechargeable polymer beads, seeds of Moringa Oleifera tree, aerobic granular sludge technology, resin based treatment and two-pronged water treatment technology.Key Words: Water PollutionWastesWater TreatmentNew TechniquesPure Water

Dentistry is neither an allied health profession nor a paramedical profession. It is the only anatomically focused health care profession that is university-based and for which primary care responsibility is maintained by the profession. Dentists must have a reliable knowledge of basic clinical medicine for safely and effectively treating individuals with chronic and other diseases, which make them biologically and pharmacologically compromised. With changes in the life expectancy of people and lifestyles, as well as rapid advancement in biomedical sciences, dentists should have similar knowledge like a physician in any other fields of medicine. There are number of primary care activities that can be conducted in the dental office like screening of diabetics, managing hypertension etc., The present review was conducted after doing extensive literature search of peer-reviewed journals. The review throws a spotlight on these activities and also suggests some the measures that can be adopted to modify dental education to turn dentists to oral physicians.

Progress in health care technologies has enabled patients to be better informed about all aspects of health care. Patients' informed consent is a legal regulation and a moral principle which represents patients' rights to take part in the clinical decisions concerning their treatment. With increasing awareness among the patients, the concept of informed consent is also evolving in developing countries like India. It is important for the medical and dental practitioners to have a written and signed informed consent from their patients before performing any invasive or irreversible procedures. Informed consent is also needed when providing medical care to children, foreign patients, and incorporating images of the patients while conducting medical and dental research. The present review addresses some of the vital issues regarding informed consent when providing medical and dental care with current review of the literature.

OBJECTIVES: To determine the level of Streptococcus mutans (S. mutans) in adults of Chandigarh and to correlate the dental caries in these individuals with their S. mutans titers. MATERIALS AND METHODS: Salivary levels of Streptococcus mutans, using Dentocult SM commercial kits were estimated in 200, 25-35 year old adults (males and females). Streptococcus mutans were detected in 87% of the study sample. Score 2, representing 10(5)-10(6) CFU/ml (Colony Forming Unit) of saliva was found to be most prevalent, i.e. in 80 of 200 adults, followed by score 1, depicting S mutans with <10(5) CFU/ml, in 56 of 200 adults and score 3, with bacterial titer >10(6) CFU/ml in 38 of 200 adults. RESULTS: Dental caries, recorded using Møller's index, was found to be maximum in individuals with score 3, followed by score 2,1 and 0, thereby showing a positive correlation of dental caries with increasing titers of S. mutans. This correlation was statistically highly significant in males with figures as 8.73 decayed surfaces at score 2 rising to 17.38 at score 3. The mean of DMFT was higher among females than in the males in the present study. CONCLUSION: The split up data in males and females, showed a positive association between caries experience and salivary S. mutans scores. The results of the study will serve as a baseline data for future planning of preventive programs in adults.
