Objectives: The aim of the present study was to assess the oral health status and treatment needs among bank employees in Bangalore city. The possible association of stress in the pathogenesis of any oral disease was investigated. Methodology: The study participants consisted of 1312 bank employees belonging to different age groups selected randomly from various banks. The participants were interviewed to asses their dietary habits, lifestyle habits and oral hygiene practices. The occupational stress levels in the subjects were evaluated using a stress related questionnaire. The oral health status and treatment needs were recorded using standard WHO proforma 1997 [modified]. Results: The results of the survey indicated that majority of the bank employees were moderately stressed out (69.1%) due to their nature of work. The stress levels exhibited by the subjects were associated with development of periodontal disease and dental caries. There was a positive correlation found between the increase in age and progression of periodontal disease (p 0.001) and dental caries (p 0.001). Conclusion: The results of the study provided evidence to understand that the bank employees find very little time to relax during their busy work schedule. The cumulative effect of oral diseases like dental caries and periodontal disease was greater. Necessary changes have to be advocated at work place to reduce abnormal stress and provide this vulnerable group a harmonious environment devoid of abnormal stress so that the initiation and progression of oral diseases is intercepted at the earliest for the achievement of optimal oral health status.

Only an individual who has made substantial intellectual contributions should be an author. Defining about what constitutes authorship is slightly controversial. According to International Committee of Medical Journal Editor {ICMIE}, to qualify as an author one should 1. have made substantial contributions to conception and design, or acquisition of data, or analysis and interpretation of data; 2. have been involved in drafting the manuscript or revising it critically for important intellectual content; and 3. have given final approval of the version to be published. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. Very frequently we fmd Thesis or dissertation of Postgraduate students published in our journals which contain multiple authors. Since authorship is a very valuable piece of intellectual property, two key issues what I would like to highlight through this review is who should be considered as first author in such publications? And the second issue is 'undeserved authorship'. The ICMJE guidelines are a good starting point for determining who qualifies to be an author, but they do not provide detailed guidance applicable for all situations. Furthermore some journals have adopted a system of listing contributors rather than authors. Therefore, the individual requirements of different journals should be respected.

The backbone of patients participation in a clinical study is informed consent. The Belmont Report suggests that informed consent should consist of three components: information about the research that is going to take place, evaluation of risks and benefits, and the ability of the participant to knowingly volunteer. The idea of informed consent in research is multifactorial and includes issues beyond an agreement to participate. The principles that rule the conduct of modem medicine, i.e. autonomy, beneficence and justice, should be implemented in decision-making. There is a need to improve informed consent documents in terms of their length and also their perceived purpose, which is to explain full details of the research.. Difficulties faced with vulnerable populations, ethnicity and cultural beliefs, language, a patient's educational level, children, pregnant women, prisoners, warrant a simplification of the consent forms. Informed consent is essential to protect the participants, not the researchers and institutions.

In dentistry one of the common modes of disease transmission is through inhalation of aerosols or droplets containing pathogens. The aim and objectives of this study was to perform qualitative and quantitative bacterial analysis of dental aerosols before, during and after clinical procedures in multichair dental environments, and to compare the consequent findings. The study was performed by collecting aerosol samples from the respective dental departments by placing the culture media plates 2 feet away from the patient's mouth, before, during and after clinical procedures. The samples were incubated aerobically at 37΀C for 48 hrs. Bacterial colony counting was performed and expressed as colonies per media plate (C/plate). The results revealed three main organism types (S. Epidermidis; S. Aureus; Diphtheroids) followed by other species. The largest bacterial colony counts were seen in the periodontics department, and the least count in the department of prosthodontics. t-test carried out to see if any significant difference existed in the colony counts between the various departments failed to demonstrate significant variations. The data from the present study confirms a potential transmission route for infectious agents in a multichair dental environment and supports the importance of protecting against cross infectious agents contained in dental aerosols.

Periodontal diseases are very common in all populations. It is an infection mediated destruction of tooth supporting tissues and it is caused by host originating substances released by host inflammatory cells and activated tissue cells. In order to improve the treatment success, to enhance host resistance rate, to decrease the recurrence rate of periodontitis, and to inhibit the biological and mechanical irritants involved in the progression of periodontitis, the ameliorative effects of herbal drugs on periodontitis have been effectively addressed by new functional drugs. Bioflavonoids are prominent natural antioxidants, free radical scavengers, in general they have not been associated with any consistent side effects. Excess intake is simply excreted in the urine as they are water soluble nutrients, and they are of recent research interest through its various therapeutic activities, demonstrating antimicrobial and anti-inflammatory properties and a potentially valuable therapeutic tool for the treatment of variety of inflammatory conditions. Foods in this category contain natural ingredients that promote health by specific metabolic actions such as modulating the inflammatory response, inhibiting the growth of pathogenic organisms, promoting healing, fortifying tissue integrity, and hindering malignant transformation. Thus it could be suggested that dietary supplementation of bioflavonoid may be used as a preventive agent in those subjects who have a susceptibility to periodontal disease.

Dentist must be called as oral physicians in order to justify their work-potential. Dentists are individuals who autonomously and definitively apply the principles of health science to the prevention, treatment and healing of disease. Individuals who autonomously and definitively apply the principles of health science to the prevention, treatment, and healing of disease are physicians. Dentistry has developed an important identity as a fully responsible, scientifically based, and anatomically focused profession linked to medicine. However, conceptually, dentistry is not a discipline distinct from medicine; dentistry is medicine. On the contrary, government and industry develop separate standards for oral health, as if the mouth could be physically separated from the body, thus erroneously narrowing down a very huge scope of a comprehensive oral health care to a trivial confme of merely dental treatment.

Supernumerary teeth are defined as an excess in the number of teeth when compared to the normal dental formula. The prevalence of non-syndrome multiple supernumerary teeth are comparatively lesser in prevalence. The term 'supplemental' is however used when the teeth are extra but have the shape and size of normal teeth. The etiology of supernumerary or supplemental teeth is ambiguous, with different factors giving rise to different types of supernumeraries with combined etiological factors responsible for same. Supernumeraries generally cause problems of malocclusion of local nature like tipping of adjacent teeth, rotation, bodily displacement, delayed eruption or prevent eruption of tooth of normal series. Also, they may lead to esthetic disharmony and functional distortion. Since the supplemental teeth did not cause alterations in the eruption, position or integrity of the permanent dentition, a conservative approach was preferred.

Honey has been rediscovered by the medical profession. Greater scientific understanding of how it works, particularly as an antibacterial agent, has led practitioners to reconsider the therapeutic value of honey. So this article is aimed at rediscovering the antimicrobial properties of honey and to synthesize the role of honey in oral health care. After having reviewed all the uses of honey in dentistry it can be concluded that, historical honey has been rediscovered to have many healing properties. With a broad spectrum antibacterial activity, honey can be given a place in therapeutics, but with more conduction of clinical trials and research on the better available preparations of honey. Honey may also be useful to promote oral hygiene in the general population. Further research in to this area needs to be done to determine honey's usefulness in oral health.

Ozone is a naturally occurring compound consisting of three oxygen atoms. Usually it is found in the stratosphere in the form of a gas. It is an antimicrobial agent which has got the highest oxidation potential against bacteria, fungi, viruses, and protozoa. Also it has got the capacity to stimulate blood circulation as well as immune response. It is universally accepted that the oxidant potential of ozone induces the destruction of cell walls and cytoplasmic membranes of bacteria and fungi. During this process, ozone attacks glycoprotein, glycolipids, and other amino acids and inhibits and blocks the enzymatic control system of the cell. Finally increases the membrane permeability, the key element of cell viability, leading to immediate functional cessation. It is also widely used for the treatment of alveolitis as a replacement for antibiotic therapy, as a mouthwash for reducing the oral microflora. remineralization of incipient dental caries as well as the adherence of microorganisms to tooth surfaces. The reliable microbiologic and metabolic properties of ozone, in either the gaseous or aqueous phases, make it a useful disinfectant with a wide range of activity. Also, the ozone can attack many biomolecules, such as the cysteine, methionine, and the histidine residues of proteins. Because of this nature of ozone, its application in dentistry and medicine has been indicated for the treatment of more than 250 different pathologies.

Background: Exposure to Human Immuno Deficiency Virus (lflV) is a matter of concern for Dental Health Care Workers (DHCW). The extent of risk to DHCW depends on prevalence of infection in patient population. A majority of patient's lllV status is unknown at the time of initial presentation. Despite following universal precautions, accidental exposure may occur while segregating and cleaning the instruments. The lack of data pertaining to awareness of post -exposure prophylaxis (PEP) among non-teaching staff is the basis behind this study. Methods: A structured questionnaire was given to 60 non-teaching staff. This questionnaire study was designed to gauge the awareness among non-teaching staff in Mangalore city regarding the risk of lllV transmission. appropriate first aid treatment immediately following exposure, estimation of risk of transmission. drugs used for PEP, duration of PEP regime, cost of the PEP, time intervals to test lllV after taking PEP drugs and when prophylaxis should be commenced. Results: Fifty-one respondents (81%) knew whom to contact immediately after accidental exposure, while only sixteen (26.7%) respondents knew that washing with soap and water was the initial measure. Though more than half of the respondents knew that prophylaxis should be initiated within one hour of injury, only twenty respondents knew the correct duration of PEP. Conclusion: Ongoing awareness and training programmes are necessary to improve the awareness about PEP among non-teaching staff.
