    Caries disease is multifactorial. Whether caries disease will be expressed and damage dental hard tissue is dependent on the patient's own unique make-up of pathogenic risk factors and protective factors. Objectives This manuscript will review the science of managing caries disease based on assessing caries risk. Methods The caries balance/imbalance model and a practical caries risk assessment procedure for patients aged 6 years through adult will illustrate how treatment options can be based on caries risk. Results Neither the forms nor the clinical protocols are meant to imply there is currently only one correct way this can be achieved, rather are used in this manuscript as examples only. Conclusions It is important to have the forms and protocols simple and easy to understand when implementing caries management by risk assessment into clinical practice. The science of CAMBRA based on the caries balance/imbalance model was reviewed and an example protocol was presented. © 2012 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    Full Text Available Abstract The number of new technologies emerging each year in the realm of dental caries management is growing at an exponential rate. Examining the patent literature, one can see that this growth rate will likely continue, with the outcome that dentistry will see an expanded growth in managing dental caries by risk assessment with medicinal therapeutic interventions. Restorative dentistry solutions, treating the results of dental caries, will continue to grow, while technologies to identify the caries process at its earliest stages will soon invade practices everywhere. The most interesting aspect of these changes will be how industry responds to the inexorable, yet slow change in dental professional demand for these new technologies, while trying to be the "first to market" within the various categories of this business opportunity. This paper will take a close look at how businesses with the core competence to be key players in this emerging growth category will assess the marketplace, and match up their business interests with the changing needs of the dental profession. The paper will also address the strategic planning and business processes that the dental industry will undertake to bring new technologies to market, and how these technologies will be positioned to health care professionals and consumers. The results of the key interactions between industry and the dental profession will determine the extent to which dental caries is managed as a disease, in addition to being managed by surgical restorative interventions.

    Full Text Available Silver nitrate has been adopted for medical use as a disinfectant for eye disease and burned wounds. In dentistry, it is an active ingredient of Howe’s solution used to prevent and arrest dental caries. While medical use of silver nitrate as a disinfectant became subsidiary with the discovery of antibiotics, its use in caries treatment also diminished with the use of fluoride in caries prevention. Since then, fluoride agents, particularly sodium fluoride, have gained popularity in caries prevention. However, caries is an infection caused by cariogenic bacteria, which demineralise enamel and dentine. Caries can progress and cause pulpal infection, but its progression can be halted through remineralisation. Sodium fluoride promotes remineralisation and silver nitrate has a profound antimicrobial effect. Hence, silver nitrate solution has been reintroduced for use with sodium fluoride varnish to arrest caries as a medical model strategy of caries management. Although the treatment permanently stains caries lesions black, this treatment protocol is simple, painless, non-invasive, and low-cost. It is well accepted by many clinicians and patients and therefore appears to be a promising strategy for caries control, particularly for young children, the elderly, and patients with severe caries risk or special needs.

    Full Text Available Dental caries is a multifactorial disease that affects most populations throughout the world and it is still the primary cause of oral pain and tooth loss. The occlusal surfaces of posterior teeth are the most vulnerable sites for dental caries due to their anatomy. Therefore, the aim of the following article is to summarize current knowledge on occlusal caries development and the possibilities of its prevention. Although the overall caries rate today has fallen for populations in industrialized countries, the rate of occlusal surface caries has not decreased. This may be explained with fact that topically applied fluorides and their mode of action prevent caries better on smooth than on occlusal surfaces. As we know, tooth decay of first permanent molars causes a great deal of different short and long term difficulties for patients. Therefore, there is a continuous need for implementation of programs for caries prevention in permanent teeth. Nowadays, we like to treat our patients by minimally invasive methods. A very important step in our effective preventive treatment is sealing pits and fissures as a cornerstone of occlusal caries management. Reliable assessment of caries activity is also very important for defining treatment needs and plans. A very important decision, which should be made during occlusal caries management, is the selection of restorative material according to the treatment plan. Conclusion. Current possibilities in occlusal caries prevention and management are very effective. Therefore, dentists today do not have any excuse for avoiding the philosophy of Minimally Invasive Dentistry, especially when we talk about caries management of occlusal surfaces in permanent molars.

    The current trend in treating dental caries is using nondestructive risk-based caries management strategies rather than focusing on the restorative treatment alone. Currently, there have been many changes in understanding of the multifaceted nature of caries process and its management. Caries Management by Risk Assessment (CAMBRA) which is an evidence-based approach focuses on determining many factors causing the expression of disease and take corrective action. The clinicians can ascertain what behaviors are increasing a patient's risk for disease and disease progression by evaluating the current caries risk of a patient. With this modern CAMBRA protocol, a novel treatment plan can be designed to arrest dental caries thereby decreasing the chance of cavitation. After the recognition of the multi factorial nature of caries involving the biofilm, the contemporary approaches focused mainly on the various options to cope with the locally out-of-balance oral biofilm and stop the progression of the disease. The initial caries lesions can be diagnosed with modern diagnostic aids and with the help of CAMBRA, reestablishment of the integrity of the tooth surface early on in the caries process will bring great rewards for patients. This review focuses on the repair of hard tooth tissues using noninvasive strategies. PMID:26538870

    2014-06-01

    Caries management by risk assessment represents best practices and is an evidence-based model that focuses on treating and preventing disease at the patient level rather than a surgical/restorative approach at the tooth level. Dental caries is a multifactorial, biofilm and pH mediated disease that affects people of all ages and disproportionally affects certain populations at epidemic proportions. Simply restoring cavitated teeth does nothing to resolve the disease. At the heart of the CAMBRA philosophy is identifying the patient's unique risk level for future caries disease. This can be done by completing a caries risk assessment (CRA). Several easy to use CRA questionnaires are available. Once the patient's unique risk level has been determined, preventive and therapeutic interventions, based on the specific risk level, can then be implemented. Landmark publications, original research, and systematic reviews are analyzed and reviewed to form the basis for this shift in patient care related to caries disease. Caries management by risk assessment has emerged as the new paradigm in patient care and represents an evidence-based, best practices approach with the potential for significant advantages over traditional methods.

    2009-10-01

    In the quest to conquer dental caries, caries management by risk assessment (CAMBRA) is a significant tool. Using CAMBRA methodology, the clinician identifies the cause of disease by assessing each patient's risk factors. By managing risk factors, the clinician then corrects the problems. Through the use of risk assessment, CAMBRA focuses on predicting likelihood of disease. In addition, the present condition of the patient needs to be addressed. That is to say, a diagnosis is needed. This article suggests that including a diagnosis with risk assessment adds to the understanding and improves management of dental caries. A simplified caries treatment protocol is presented, using these concepts.

    Dentists often report that treating children in their practices is either the most rewarding or the most challenging of all their professional experiences. Special considerations must be made for the biology of the caries process, the psychological development of the child, parental involvement, the complex environmental factors that contribute to caries, and the wide variety of clinical treatment options available. Caries management by risk assessment (CAMBRA) is becoming the standard of care for dental professionals. Although significant progress has been made against caries in the past 30 years, very resistant pockets of disease remain in certain demographics. This article presents a number of different clinical scenarios, which will explore diagnostic and restorative protocols that apply to children who are at risk for caries.

    Dental caries is a disease induced by dental plaque, which can be described as a community of microorganisms (biofilm). Because of genetic and environmental factors a number of changes in the oral microbiome takes place; in case of commensalism and mutualism between biofilm microorganisms and the host, homeostasis in oral microbiome is maintained. However, when a risk factor occurs parasitic relationship starts prevailing and activity of the pathogenic cariogenic microorganisms increases leading to a dental caries. According to the newest technologies of molecular microbiology new cariogenic microorganisms species have been determined. Each individual's oral microbiome is as unique as his/her immune system; therefore, commonly taken caries prevention measures cannot be of the same effectiveness for all individuals. Each person has his own caries risk which is determined by the oral microbiome and immune system influenced by the environmental and genetic factors. Early caries diagnostic, risk assessment and individualized caries prevention plan will allow us to control the disease and achieve a desirable effect. For the dentist the most important thing is not to treat the consequences of the disease - cavities - but be aware of the dental caries as a biological phenomenon.

    2005-01-01

    Part two of this series discussed the key strategies that each practice should focus on for caries management. History has proven that oral hygiene and "drilling and filling" alone will not eliminate dental caries. Chemical treatments to prevent and reverse early lesions and conservative, tooth-preserving restorative procedures when surgical intervention is necessary should be the new standard of care. Caries management by risk assessment (CAMBRA), where risk factors are "re-balanced" to that of health, is a sound strategy that is one step closer to "curative" dentistry and improving the quality of life of dental patients. The final article in this series will discuss the role that glass-ionomer materials and hard tissue lasers play in the minimally invasive restorative procedures for dental caries.

  18. The Evidence for Caries Management by Risk Assessment (CAMBRA®).

    2018-02-01

    A system for Caries Management by Risk Assessment (CAMBRA ® ) has been developed in California. The purpose of this article is to summarize the science behind the methodology, the history of the development of CAMBRA, and the outcomes of clinical application. The CAMBRA caries risk assessment (CRA) tool for ages 6 y through adult has been used at the University of California, San Francisco (UCSF), for 14 y, and outcome studies involving thousands of patients have been conducted. Three outcomes assessments, each on different patient cohorts, demonstrated a clear relationship between CAMBRA-CRA risk levels of low, moderate, high, and extreme with cavitation or lesions into dentin (by radiograph) at follow-up. This validated risk prediction tool has been updated with time and is now routinely used at UCSF and in other settings worldwide as part of normal clinical practice. The CAMBRA-CRA tool for 0- to 5-y-olds has demonstrated similar predictive validity and is in routine use. The addition of chemical therapy (antibacterial plus fluoride) to the traditional restorative treatment plan, based on caries risk status, has been shown to reduce the caries increment by about 20% to 38% in high-caries-risk adult patients. The chemical therapy used for high-risk patients is a combination of daily antibacterial therapy (0.12% w/v chlorhexidine gluconate mouth rinse) and twice-daily high-concentration fluoride toothpaste (5,000 ppm F), both for home use. These outcomes assessments provide the evidence to use these CRA tools with confidence. Caries can be managed by adding chemical therapy, based on the assessed caries risk level, coupled with necessary restorative procedures. For high- and extreme-risk patients, a combination of antibacterial and fluoride therapy is necessary. The fluoride therapy must be supplemented by antibacterial therapy to reduce the bacterial challenge, modify the biofilm, and provide prevention rather than continued caries progression.

  19. Ozone therapy in the management and prevention of caries

    Full Text Available The purpose of this article was to assess the effectiveness of ozone therapy in the management and prevention of caries, reviewing clinical and in vitro studies. Ozone has proven to be effective against gram-negative and gram-positive bacteria, viruses, and fungi. In dentistry, most of the published articles are based on ozone's antimicrobial effects and the treatment of caries. Most of the clinical studies reported ozone to be a promising alternative to conventional methods for caries management. However, a few studies have shown ozone to be insufficient for preventing caries and reducing microorganisms in open occlusal carious lesions. Ozone might be a useful tool to reduce and control oral infectious microorganisms in dental plaque and dental cavity. However, the results of in vitro studies are controversial; while some researchers reported that ozone therapy had a minimal or no effect on the viability of microorganisms, others suggested ozone to be highly effective in killing both gram-positive and gram-negative oral microorganisms. Therefore, more evidence is required before ozone can be accepted as an alternative to present methods for the management and prevention of caries.

  20. Managing Early Childhood Caries for Young Children in China

    Full Text Available The latest national survey found that 70% of 5-year-old children in China had dental caries. The prevalence of early childhood caries (ECC may not only be attributed to poor oral hygiene and unhealthy diet, but also to limited access to and availability of dental care. The prevailing preventive measures adopted by industrialised countries for ECC management are neither practical nor affordable in China. Hence, an alternative approach to ECC management is necessary. Atraumatic restorative treatment (ART has been advocated because the simple and short operative time renders ART affordable. However, the success rate of ART in restoring anterior primary teeth is unfavourable. Although there is no water fluoridation in China, topical fluorides may be used to manage ECC. Tooth brushing with fluoride toothpaste is effective for caries control, but not all toothpastes in China are fluoridated. Professionally applied fluorides such as sodium fluoride varnish can be a cost-effective treatment for managing the high prevalence of ECC in China. Silver diamine fluoride (SDF at 38% is suggested to be effective in arresting ECC in China. It can be a simple, non-invasive and low-cost treatment. However, it stains caries black. Children and their parents must be well informed before SDF treatment.

  1. Diagnosis and management of dental caries throughout life.

    Science.gov (United States)

    To provide health care providers, patients, and the general public with a responsible assessment of currently available data regarding the diagnosis and management of dental caries throughout life. A non-Federal, non-advocate, 13-member panel representing the fields of dentistry, epidemiology, genetics, medicine, oral biology, oral radiology, pathology, periodontics, public health, statistics, surgery, and including a public representative. In addition, 31 experts in these same fields presented data to the panel and to a conference audience of approximately 700. Presentations by experts; a systematic review of the dental research literature provided by the Agency for Healthcare Research and Quality; and an extensive bibliography of dental caries research papers, prepared by the National Library of Medicine. Scientific evidence was given precedence over clinical anecdotal experience. Answering predefined questions, the panel drafted a statement based on the scientific evidence presented in open forum and the scientific literature. The draft statement was read in its entirety on the final day of the conference and circulated to the experts and the audience for comment. The panel then met in executive session to consider these comments and released a revised statement at the end of the conference. The statement was made available on the World Wide Web at http://consensus.nih.gov immediately after the conference. This statement is an independent report of the panel and is not a policy statement of the NIH or the Federal Government. This Consensus Development Conference, the first sponsored by the NIH on dental caries, provided an excellent venue to describe the great success that has been achieved in reducing caries prevalence. More importantly, it provided a public forum to review both the strengths and weaknesses of current dental caries research and clinical procedures. Effective preventive practices, such as the use of fluoride, sugarless products, and dental

    Research has demonstrated the validation of specific caries risk assessment (CRA) systems, but little is known about how dental practitioners assign a caries risk level to their patients. The aim of this study was to explore dental students' decision making in caries risk assignment when using the Caries Management By Risk Assessment (CAMBRA) system. Multiple correspondence analysis and chi-squared automated interaction detector analysis were performed on data collected retrospectively for a period of six years (2003-09) at the University of California, San Francisco predoctoral dental clinic. The study population consisted of 12,952 patients from six years of age through adult who received a baseline CRA during the period, were new to CAMBRA, and had not received any prior CAMBRA recommendations. The results showed variation in decision making and risk level assignment, illustrated by the range of percentages for the three scores (low, moderate, and high/extreme caries risk) when CRA was assigned for the first time. For those first-time CRAs, decision making was mainly based on four factors: cavities or caries lesions into dentin on radiograph, restorations during the last three years due to caries, visible heavy plaque, and interproximal lesions into enamel (by radiographs). This study's findings provide important data regarding one group of CAMBRA users and thus contribute to the development of knowledge about the implementation of caries risk assessment in contemporary dental practice.

    Until recently, the standard of care for early childhood caries (ECC) has been primarily surgical and restorative treatment with little emphasis on preventing and managing the disease itself. It is now recognized that surgical treatment alone does not address the underlying etiology of the disease. Despite costly surgeries and reparative treatment, the onset and progression of caries are likely to continue. A successful rebalance of risk and protective factors may prevent, slow down, or even arrest dental caries and its progression. An 18-month risk-based chronic disease management (DM) approach to address ECC in preschool children was implemented as a quality improvement (QI) collaborative by seven teams of oral health care providers across the United States. In the aggregate, fewer DM children experienced new cavitation, pain, and referrals to the operating room (OR) for restorative treatment compared to baseline historical controls. The teams found that QI methods facilitated adoption of the DM approach and resulted in improved care to patients and better outcomes overall. Despite these successes, the wide scale adoption and spread of the DM approach may be limited unless health policy and payment reforms are enacted to compensate providers for implementing DM protocols in their practice.

    This study evaluated the knowledge of dental assistants (DA) and hygienists (DH) on dental trauma management and dental caries prevention. Secondarily, other aims were 2-fold: (1) to update the assistants/hygienists through courses supported on scientific evidence-based information and (2) to evaluate their job satisfaction. A cross-sectional study was conducted with 46 participants, DHs and Das, working in the Secretary of Education of the city of Brasilia (Federal District, Brazil). The information was gathered through 2 self-administered questionnaires during 2 training meetings. The first questionnaire was applied before the first meeting and the second questionnaire after the last meeting. All participants were women older than 38 years and with more than 15 years of experience. The participants demonstrated knowledge on dental trauma types but lack of knowledge on dental trauma first-aid approaches. Concerning to dental caries, the professional demonstrated knowledge on both etiology and prevention. Lectures, periodical training, and inclusion in multidisciplinary training groups aiming to caries prevention and dental trauma are necessary.

    Preservation of natural tooth structure requires early detection of the carious lesion and is associated with comprehensive patient dental care. Processes aiming to detect carious lesions in the initial stage with optimum efficiency employ a variety of technologies such as magnifying loupes, transillumination, light and laser fluorescence (QLF® and DIAGNOdent® ) and autofluorescence (Soprolife® and VistaCam®), electric current/impedance (CarieScan(®) ), tomographic imaging and image processing. Most fluorescent caries detection tools can discriminate between healthy and carious dental tissue, demonstrating different levels of sensitivity and specificity. Based on the fluorescence principle, an LED camera (Soprolife® ) was developed (Sopro-Acteon, La Ciotat, France) which combined magnification, fluorescence, picture acquisition and an innovative therapeutic concept called light-induced fluorescence evaluator for diagnosis and treatment (LIFEDT). This article is rounded off by a Soprolife® illustration about minimally or even non-invasive dental techniques, distinguishing those that preserve or reinforce the enamel and enamel-dentine structures without any preparation (MIT1- minimally invasive therapy 1) from those that require minimum preparation of the dental tissues (MIT2 - minimally invasive therapy 2) using several clinical cases as examples. MIT1 encompasses all the dental techniques aimed at disinfection, remineralizing, reversing and sealing the caries process and MIT2 involves a series of specific tools, including microburs, air abrasion devices, sonic and ultrasonic inserts and photo-activated disinfection to achieve minimal preparation of the tooth. With respect to minimally invasive treatment and prevention, the use of lasers is discussed. Furthermore, while most practices operate under a surgical model, Caries Management by Risk Assessment (CaMBRA) encourages a medical model of disease prevention and management to control the manifestation of the

  10. TRManager – Technical Risk Manager

    Directory of Open Access Journals (Sweden)

    Mark A. Gregory

    2009-06-01

    Full Text Available This paper presents research into the development of a new information management technique called Technical Risk Manager. Project management involves the use of processes and information management techniques to aid decision making in the pursuit of project success. Project success may be achieved by meeting time, cost or performance criteria. Current project management practices focus on achieving time and cost project success criteria by using three information management techniques developed in the 1950s: Gantt, PERT and Critical Path Method. Technical Risk Manager has been developed to provide an information management technique that may be used to aid project management decision making in the pursuit of achieving the performance project success criteria.

    Health registries are commonly used in medicine to support public health activities and are increasingly used in quality improvement (QI) initiatives. Illustrations of dental registries and their QI applications are lacking. Within dentistry, caries risk assessment implementation and documentation are vital to optimal patient care. The purpose of this article is to describe the processes used to develop a caries risk assessment registry as a QI initiative to support clinical caries risk assessment, caries prevention, and disease management for children. Developmental steps reflected Agency for Healthcare Research and Quality recommendations for planning QI registries and included engaging "champions," defining the project, identifying registry features, defining performance dashboard indicators, and pilot testing with participant feedback. We followed Standards for Quality Improvement Reporting Excellence guidelines. Registry eligibility is patients aged 0-17 years. QI tools include prompts to register eligible patients; decision support tools grounded in evidence-based guidelines; and performance dashboard reports delivered at the provider and aggregated levels at regular intervals. The registry was successfully piloted in two practices with documented caries risk assessment increasing from 57 percent to 92 percent and positive feedback regarding the potential to improve dental practice patient centeredness, patient engagement and education, and quality of care. The caries risk assessment registry demonstrates how dental registries may be used in QI efforts to promote joint patient and provider engagement, foster shared decision making, and systematically collect patient information to generate timely and actionable data to improve care quality and patient outcomes at the individual and population levels. © 2017 American Association of Public Health Dentistry.

    2011-01-01

    In the past, the approach for treating caries was mainly symptomatic and involved removal of caries, teeth restoration, oral hygiene instructions, and fluoride applications in cases that presented with significant disease. As the bacterial component of the disease was revealed, questions emerged concerning the significance of each strain present and intervention in the process of caries development. This article reviews the evidence that supports the implementation of the current caries risk assessment and management protocol (CAMBRA). It details the current risk factors, techniques and devices for assessing them and, interventions that should be considered in order to address the risk. The paper defines specific guidelines for managing risks related to caries. Intervention should be customized according to the risk determined for each specific patient.

    2016-10-01

    A new clinic conception, healthy cosmetic management (HCM), was innovated introduced into diagnose and treatment of patients with high caries risk. The priority of HCM should be given to aesthetic restoration of teeth, taking consideration of the conserving of tissue and pulp of teeth and the balance between health and aesthetics, which may reach to the goal of the individual clinic treatment. HCM includes five steps: 1) caries risk assessment; 2) detection of initial caries; 3) digital aesthetic design; 4) minimally invasive therapy; 5) behavior management of caries and doctor-patient communication pattern. In this article, HCM is introduced into two aspects: process management and clinical protocols, followed by the combination of the clinical practice.

    The Technical Assistance Contractor (TAC) for the Uranium Mill Tailings Remedial Action (UMTRA) Project comprises Jacobs Engineering Group Inc. (JEG) and its major teaming partners [Roy F. Weston, Inc. (RFW), Sergent, Hauskins ampersand Beckwith Agra, Inc. (SHB Agra), and Geraghty ampersand Miller, Inc. (G ampersand M)]. The first three companies have worked together effectively on the UMTRA Project for more than 10 years. With the initiation of the UMTRA Groundwater Project in April 1991, a need arose to increase the TAC's groundwater technical breadth and depth, so G ampersand M was brought in to augment the team's capabilities. The TAC contract's scope is to provide technical, analytical, environmental, engineering, design, inspection, and management support services to the US Department of Energy (DOE) for both surface and groundwater projects. The TAC team continues to support the DOE in completing surface remedial actions and initiating groundwater remediation work for start-up, characterization, design, construction oversight, and remedial operations. A key feature of the TAC's management approach is the extensive set of communication systems implemented for the UMTRA Project. These systems assist all functional disciplines in performing UMTRA Project tasks associated with management, technical support, administrative support, and financial/project controls

    Systematic and effective control of age-related degradation of safety-related components, systems, and structures in nuclear power plants (NPPs) is an important challenge to plant operators. Several data bases, available to provide guidance on aging management, are summarized. However, the ultimate consideration is: How effectively is aging management being implemented at individual plants? Illustrated here is a specific strategy that served to develop the technical data base for the Nuclear Plant Aging Research Program. The strategy is comprehensive, systematic, and adaptable. Effective aging management at NPPs could be facilitated by a parallel strategy. The elements of a strategy are suggested

    Full Text Available In the control of occlusal caries, the major challenges are related not only to the detection of non-cavitary lesions, but also to the establishment of the treatment strategies to be subsequently applied. Considering the objective of each treatment, that of helping the patient, it is essential to control the progression of carious lesions by means of nonsurgical, preventive/therapeutical methods, whenever necessary. The new strategies applied in caries management are based on the evaluation and predictibility of possible risks, a major aspect in the daily taking of therapeutical decisions. The management plan should include: (I patient’s level of risk, (II patient’s activity level and (III severity of the lesion. Various strategies for a most efficient management of patient’s problems, as well as of the carious lesions, have been elaborated by specialized medical organisms, such as: strategies established within ICDAS, CAMBRA, strategies of the caries management system (SMC and protocols indicated by the system of caries classification according to ADA (American Dental Association. The mission of any new model of caries management is first of all to preserve the dental tissues, and to restore them when only recommended – an idea to guide the decisions of practitioners, starting with the moment of anamnesis, clinical examination and estabishment of diagnosis, until the end of the treatment

    Lifelong control of disease processes associated with dental caries should be an essential part of the process of care for practicing dental hygienists. The purpose of this study was to identify the knowledge, attitudes and practice behaviors among dental hygienists regarding caries risk assessment (CRA) and management. Utilizing the American Dental Hygienists' Association (ADHA) Survey/Research Center database of all registered dental hygienists in the U.S., 2,500 actively licensed dental hygienists were randomly selected and sent a web-based survey via SurveyMonkey™. The survey included items about practice characteristics and questions regarding knowledge, attitudes and practice behaviors regarding CRA and management. Second and third emails were sent to non-respondents. A 4-point Likert type scale (1=never, 2=sometimes, 3=frequently and 4=always) was used to rate the occurrence of caries management recommendations used in the practice setting. Frequencies and percentiles were used to evaluate demographic, knowledge and attitude information. The response rate was 9% (n=219) - 87% were ADHA members. Participants reported a high level of comfort (89%) in performing CRA, yet only 23% used an established CRA/management instrument. Over-the-counter fluoride dentifrices (70.1%), individualized oral hygiene instructions (86%) and individualized recare intervals (73.7%) were most often used as caries management recommendations, while low-dose fluoride rinses (45%) and prescription strength sodium fluoride gel or paste (42%) were used less frequently. Dental hygienists scored high on knowledge of CRA with the exception of white spot lesions as a risk factor (42%) and efficacy of chlorhexidine in caries management (61%). There is a need to improve practicing dental hygienists' knowledge and involvement in the active management of caries. Focused training in the use of established CRA/management tools should be designed to improve their knowledge and influence practice

    Probiotics might be beneficial to prevent or treat caries, gingivitis or periodontitis. We aimed to appraise trials assessing probiotics for managing caries and periodontal disease. We included randomized controlled trials comparing the efficacy of probiotics versus (placebo) control with regards to Streptococcus mutans [SM], lactobacilli [LB], periodontal pathogens numbers, gingivitis, oral hygiene, caries incidence/experience increment, or periodontitis. Meta-analysis and trial-sequential-analysis were performed. Three electronic databases (Medline, Embase, Central) were screened. 50 studies (3247 participants) were included. Studies were mainly performed in children and used lactobacilli (45); bifidobacteria (12) or other genus (3). Probiotics significantly increased the chance of reducing SM (OR: 2.20, 95% CI: 1.23/3.92) or LB (OR: 2.84; 1.34/6.03)Probiotics significantly reduced bleeding-on-probing (SMD: -1.15; -1.68/-0.62) and gingival index (SMD: -0.86; -1.52/-0.20), but not plaque index (SMD: -0.34; -0.89/0.21). Caries incidence was not significantly reduced (OR: 0.60; 0.35/1.04), neither was caries experience (SMD: -0.26; -0.55/0.03) or CAL (SMD: -0.46; -0.84/0.08). In contrast, probing-pocket depths (SMD: -0.86; -1.55/-0.17) were significantly reduced. Data was quantitatively insufficient for conclusive findings, and risk of bias was high. Current evidence is insufficient for recommending probiotics for managing dental caries, but supportive towards managing gingivitis or periodontitis. Future studies should only record bacterial numbers alongside accepted disease markers or indicators. Probiotic therapy could be used for managing periodontal diseases. For caries, further studies should ascertain both efficacy and safety. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This publication describes the history of Minimal Intervention Dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the ‘surgical’ care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI’s policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing. PMID:23106836

  11. Managing Early Childhood Caries with Atraumatic Restorative Treatment and Topical Silver and Fluoride Agents

    2017-10-01

    Full Text Available Early childhood caries (ECC is a significant global health problem affecting millions of preschool children worldwide. In general, preschool children from families with 20% of the lowest family incomes suffered about 80% of the ECC. Most, if not all, surveys indicated that the great majority of ECC was left untreated. Untreated caries progresses into the dental pulp, causing pain and infection. It can spread systemically, affecting a child’s growth, development and general health. Fundamental caries management is based on the conventional restorative approach. Because preschool children are too young to cope with lengthy dental treatment, they often receive dental treatment under general anaesthesia from a specialist dentist. However, treatment under general anaesthesia poses a life-threatening risk to young children. Moreover, there are few dentists in rural areas, where ECC is prevalent. Hence, conventional dental care is unaffordable, inaccessible or unavailable in many communities. However, studies showed that the atraumatic restorative treatment had a very good success rate in treating dentine caries in young children. Silver diamine fluoride is considered safe and effective in arresting dentine caries in primary teeth. The aim of this paper is to review and discuss updated evidence of these alternative approaches in order to manage cavitated ECC.

  12. Nyvad Criteria for Caries Lesion Activity and Severity Assessment: A Validated Approach for Clinical Management and Research.

    Nyvad, Bente; Baelum, Vibeke

    2018-03-05

    The Nyvad classification is a visual-tactile caries classification system devised to enable the detection of the activity and severity of caries lesions with special focus on low-caries populations. The criteria behind the classification reflect the entire continuum of caries, ranging from clinically sound surfaces through noncavitated and microcavitated caries lesions in enamel, to frank cavitation into the dentin. Lesion activity at each severity stage is discriminated by differences in surface topography and lesion texture. The reliability of the Nyvad criteria is high to excellent when used by trained examiners in the primary and permanent dentitions. The Nyvad criteria have construct validity for lesion activity assessments because of their ability to reflect the well-known caries-controlling effect of fluoride. Predictive validity was demonstrated by showing that active noncavitated lesions are at higher risk of progressing to a cavity or filled state than do inactive noncavitated lesions. Lesion activity assessment performed successfully as a screening tool to identify individuals with a poor caries prognosis. Because of their predictive validity, the Nyvad criteria are superior to other current caries lesion descriptors for the detection of changes in the lesion activity status over time. The Nyvad criteria fulfill all the formal requirements for a robust caries lesion classification and are recommended for evidence-based caries management in clinical practice and in research. © 2018 S.

    Patients with craniofacial anomalies have an increased incidence of dental caries. The prevention program "Caries Management By Risk Assessment" (CAMBRA) has been previously validated but has not yet been introduced at a widespread level in a medical setting, particularly for this high-risk population.In this cross-sectional study, we aimed to evaluate the feasibility of implementing CAMBRA during the medical visit at an institutional tertiary care center, which treats children with craniofacial anomalies. The study included 161 participants aged 1 to 18 years. Patients and parents received a personalized educational session, toothbrushing tutorial, and fluoride varnish application. We assessed the prevalence of dental caries, caries risk factors, and knowledge of oral hygiene in this patient population.The overall caries prevalence in this group was higher than average (57% compared with 42%, according to the Centers for Disease Control and Prevention). The most prevalent risk factors were developmental delay, deep pits/fissures, low socioeconomic status, orthodontic appliances, and carbohydrate snacks. The greatest predictors of dental caries were having 1 or more risk factors and having low socioeconomic status. In summary, children with craniofacial anomalies were at high risk for dental caries, with high rates of risk factors and low rates of preventive factors.Our findings revealed that basic oral hygiene standards are not being met in this high-risk population, highlighting the need for implementation of protocols such as CAMBRA. The results of this study can aid healthcare workers in craniofacial centers and children's hospitals to improve the understanding of oral hygiene and dental care of their patients.

    The 2014 Early Childhood Caries Conference encompassed evidence-based reviews on the state of the science regarding early childhood carries (ECC) epidemiology, etiology, prevention, and disease management. The purpose of this paper was to discuss the work presented at the conference and identify opportunities in research, policy, and clinical management that may improve early childhood caries outcomes and lower costs of care. While great progress has been made since the 1997 ECC Conference, there remains a paucity of high-quality evidence from randomized controlled trials on what are the most effective means to prevent and manage ECC. Analyses of studies indicate that some approaches, such as chlorhexidine, iodine, and remineralizing agents, have not shown consistent findings in preventing ECC. However, evidence exists to yield recommendations in some areas. There are useful risk assessment indicators to identify preschool children at risk for caries. Fluoridated toothpaste and fluoride varnish currently are the most effective chemotherapeutic strategies to prevent ECC. Motivational interviewing, a form of patient-centered counseling, is effective for motivating oral health behaviors and shows promise for reducing caries. Additionally, evidence is emerging that shows the value of chronic disease management approaches and integrating ECC oral health care within medical care settings. Recommendations for future directions in ECC research and policy were also key outcomes of the conference.

    2015-05-01

    The aim of this study was to evaluate the long-term adoption of a risk-based caries management program at a university dental clinic. The authors extracted data from electronic records of adult non-edentulous patients who underwent a comprehensive oral evaluation in the university predoctoral clinic from July 2007 through June 2014 (N=21,984). Consistency with caries management guidelines was measured as the percentage of patients with caries risk designation (low, moderate, high, or extreme) and the percentage of patients provided non-operative anti-caries agents within each designated caries risk category. Additionally, patient and provider characteristics associated with risk assessment completion and with provision of anti-caries therapy were identified. Results showed that the percentage of patients with documented caries risk grew steadily from 62.3% in 2007-08 to 92.8% in 2013-14. Overall, receipt of non-operative anti-caries agents increased with rising caries risk, from low (6.9%), moderate (14.1%), high (36.4%), to extreme (51.4%), but percentages were stable over the study period. Younger patients were more likely to have a completed risk assessment, and among high- and extreme-risk patients, delivery of anti-caries therapy was more common among patients who were younger, identified as Asian or Caucasian, received public dental benefits, or were seen by a student in the four-year DDS program or in the final year of training. These results demonstrate that extensive compliance in documenting caries risk was achieved within a decade of implementing risk-based clinical guidelines at this dental school clinic. Caries risk was the most strongly associated of several factors related to delivery of non-operative therapy. The eventual success of this program suggests that, in dental education, transition to a risk-based, prevention-focused curriculum may require a long-term commitment.

    The purpose of Technical Staff and Technical Staff Managers training is to provide job skills enhancement to individuals selected to fill key technical positions within a nuclear utility. This training is unique in that unlike other training programs accredited by the National Academy for Nuclear Training, it does not lead to specific task qualification. The problems encountered when determining the student population and curriculum are a direct result of this major difference. Major problems encountered are determining who should attend the training, what amount of training is necessary and sufficient, and how to obtain the best feedback in order to effect substantive program improvements. These topics will be explored and possible solutions discussed

    Dental caries is the most prevalent non-communicative disease worldwide. Although the etiological factors are well known for years, reducing the number of decayed and missing teeth in children still remains as a barrier. Preventive and curative options are numerous but little is known about their economical advantages. Selecting the intervention that offers the best balance of effectiveness and financial resources becomes crucial in the current situation of budget restrictions worldwide. Areas covered: This expert review summarizes available evidence on cost-effectiveness analyses of preventive and curative measures to manage dental caries in children. Expert commentary: Preventive measures have been more extensively studied than dental caries treatment. Only water fluoridation and tooth brushing are well-established as cost-effective preventive approaches. Despite the increasing number of cost analysis treatment studies in the literature, most of them focus on the cost description, with no correlation to the intervention effectiveness. There is a current need of well-designed and well-reported cost-effectiveness regarding dental caries management.

    Full Text Available Primary caries is an initial lesions produced by direct extension from an external surface. Dental caries is called as tooth decay or a cavity is a disease in which bacterial processes changes carbohydrate to acid which than dematerializes the hard tooth structure like enamel, dentin and cementum. Streptococcus mutans and Lactobacillus are the bacteria responsible for the dental caries by acid production. This article throws light on the dental caries disease, its sign and symptoms, treatment and prevention of it. A review of some patents on dental caries is also provided that summarizes the recent technical advancements taken place in this area.

  5. Managing dental caries in children in Turkey--a discussion paper.

    Science.gov (United States)

    Topaloglu-Ak, Asli; Eden, Ece; Frencken, Jo E

    2009-11-25

    This paper describes the oral healthcare system and disease situation amongst children in Turkey. Considering the high prevalence and severity of dental caries, a proposal for improvement of oral health in this population group is formulated. A virtual absence of palliative, preventive and restorative care characterises juvenile oral healthcare in Turkey. Consequently, carious cavities remain untreated, which may lead to pain, discomfort and functional limitation and, further, may impact negatively upon general health and cognitive development. As a first step to controlling dental caries, a national health programme including promotional, preventive and minimal intervention approaches for managing dental caries is proposed. The pros and cons of community-oriented caries-preventive measures are discussed. Daily tooth brushing with fluoridated toothpaste at home, in mother- and child-care centres, kindergartens, and schools is highlighted. The dental profession, government, university officials and other stakeholders need to meet and determine how best the oral health of children in Turkey can be improved. The present proposed plan is considered a starting point.

    Science.gov (United States)

    Edelstein, Burton L; Ng, Man Wai

    2015-01-01

    An Institute of Medicine report places chronic disease management (CDM) as an intervention on a treatment spectrum between prevention and acute care. CDM commonly focuses on conditions in which patient self-care efforts are significant. Framing early childhood caries (ECC) as such a chronic condition invites dentistry to reconsider its approach to caries management and shift gears from a strictly surgical approach to one that also incorporates a medical approach. This paper's purpose was to explore the definition of and concepts inherent in CDM. An explanatory model is introduced to describe the multiple factors that influence ECC-CDM strategies. Reviewed literature suggests that early evidence from ECC-CDM interventions, along with results of pediatric asthma and diabetes CDM, supports CDM of ECC as a valid approach that is independent of both prevention and repair. Early results of ECC-CDM endeavors have demonstrated a reduction in rates of new cavitation, dental pain, and referral to the operating room compared to baseline rates. ECC-CDM strategies hold strong promise to curtail caries activity while complementing dental repair when needed, thereby reducing disease progression and cavity recurrence. Institutionalizing ECC-CDM will both require and benefit from evolving health care delivery and financing systems that reward positive health outcomes.

    The US Department of Energy manages wastes that are both chemically hazardous and radioactive. These mixed wastes are often unique and many have national security implications. Management practices have evolved over the more than forty years that the Department and its predecessor agencies have been managing these wastes, both in response to better understanding of the hazards involved and in response to external, regulatory influences. The Department has recently standarized its waste management practices and has initited an R and D program to address priority issues identified by its operating contractor organizations. The R and D program is guided by waste management strategy that emphasizes reduction of human exposure to hazardous wastes in the environment, reduction of the amount and toxicity of wastes generated, treatment of wastes that are generated to reduce volumes and toxicities, and identification of alternatives to land disposal of wastes that remain hazardous following maximum practicable treatment

    Hidden caries is a dentinal lesion beneath the dentinoenamel junction, visible on radiographs. A single report described this lesion in primary dentition. This case report describes a case of hidden caries in a mandibular second primary molar, misdiagnosed as malignant swelling. A 3-year-old white girl was referred to the Department of Pediatric Dentistry with a chief complaint of pain and extraoral swelling on the right side of the mandible for the last 3 months. She was earlier referred to the surgical department for biopsy of the lesion. Radiographic and computed tomography scan examination showed a periapical lesion with buccal plate resorption and radiolucency beneath the enamel on the mesial part of tooth 85. The tooth was extracted, and follow-up of 2 years showed normal development of tooth 45. The main problem is early detection and treatment, since the outer surface of enamel may appear intact on tactile examination. Gera A, Zilberman U.

  14. NEW DATA ON THE CLINICAL AND THERAPEUTICAL MANAGEMENT OF OCCLUSAL CARIES (II

    Directory of Open Access Journals (Sweden)

    Sorin ANDRIAN

    2017-03-01

    Full Text Available Due to the multifactorial etiology of the carious process and also to the dynamic character of the disease, its clinicaltherapeutical management becomes increasingly complex. The strategies applied in the management of occlusal caries have had several stages, starting with the pre-restorative period, when only few empirical and simple restorative methods were available. The following so-called ”restorative” stage was dominated by the belief of specialists and researchers that the only efficient treatment of carious lesions, whichever their evolution stage, is reconstruction of the odontal functional morphology through obturations. In the last decades of the last century, the preventive principles, supported by a better understanding of the mechanisms of action of fluoride, gained more and more space, ”the preventive stage” being now in progress. The major challenge in the management of the carious process is the control of its advance especially through preventive/therapeutical non-operative measures. The scope of any pattern of caries management is first to maintain the dental tissues, and to restore them only when recommended: such a desiderate should be considered in all decisions taken during anamnesis, clinical examination, establishment of diagnostis, until the end of the treatment.

    The Technical Assistance Contractor (TAC) for the Uranium Mill Tailings Remedial Action (UMTRA) Project comprises Jacobs Engineering Group Inc. (JEG) and its major teaming partners [Roy F. Weston, Inc. (RFW), Sergent, Hauskins & Beckwith Agra, Inc. (SHB Agra), and Geraghty & Miller, Inc. (G&M)]. The first three companies have worked together effectively on the UMTRA Project for more than 10 years. With the initiation of the UMTRA Groundwater Project in April 1991, a need arose to increase the TAC`s groundwater technical breadth and depth, so G&M was brought in to augment the team`s capabilities. The TAC contract`s scope is to provide technical, analytical, environmental, engineering, design, inspection, and management support services to the US Department of Energy (DOE) for both surface and groundwater projects. The TAC team continues to support the DOE in completing surface remedial actions and initiating groundwater remediation work for start-up, characterization, design, construction oversight, and remedial operations. A key feature of the TAC`s management approach is the extensive set of communication systems implemented for the UMTRA Project. These systems assist all functional disciplines in performing UMTRA Project tasks associated with management, technical support, administrative support, and financial/project controls.

  8. Risk management through dynamic technical specifications

    International Nuclear Information System (INIS)

    Klopp, George T.; Petersen, Thomas A.

    2004-01-01

    The wide deployment of plant specific probabilistic risk assessments for nuclear power plants has provided the means to effect a fresh risk management perspective and a fresh, risk based, regulatory outlook on nuclear power. There has been a great deal of conversation on risk based regulation within the U. S. nuclear power industry but, curiously, very little on effective risk management. This paper proposes a means to link the two subjects through the plant Technical Specifications. A revised concept for Technical Specifications is suggested which is based on deterministic analyses and probabilistic risk assessments for each plant. The revised Technical Specifications would consider, on a real-time basis, the exact state of the plant in terms of the status of key components and systems. It would depict current plant risk levels and compare those levels to the desired and limiting (alert/action) levels. It would advise the plant operator on the risk impact of proposed actions through a simple query system and illustrate the impact of such actions on plant status relative to designated risk values. The basis for the proposed approach lies in realistic deterministic plant analyses and probabilistic risk assessment (PRA) deployment tools being developed, in parallel, by a number of parties in the U.S. today. These PRAs are based primarily on the existing plant responses to Generic Letter 88-20, 'Individual Plant Examinations' (IPEs). Each of these tools allows the plant operator to input, on a real-time basis, the status of key equipment and systems. The tools then provide explicit illustrations of dependency effects; updated, 'real-time' risk status indications such as core damage frequency; and, in some cases, allow the operator to assess the risk impact of removing from service selected components for maintenance or testing. These systems generally operate on personal computers and provide nearly instantaneous responses to plant queries. Moving from these tools to

    1991-01-01

    Through many experiences in responding to real radiation accidents and emergency response exercises, the Department of Energy (DOE) has developed a technical information management system that will be used in the Federal Radiological Monitoring and Assessment Center (FRMAC) in the event of a major radiological accident. The core of the system is the Data Center in the FRMAC, utilizing a computerized database of all off-site environmental radiological data. The information contained and managed by the Data Center will be comprehensive, accountable, and traceable, providing information to the assessors for immediate health and safety needs as well as for long-term documentation requirements. A DOE task force has been formed to develop compatibility guidelines for video, automated data processing, and communication systems. An electronic mail, information status, and bulletin board system is also being developed to assist in the dissemination of information. Geographic Information Systems (GIS) offer a giant step forward in displaying and analyzing information in a geographically referenced system

    2015-02-01

    The purpose of this study was to survey dental hygienists to determine their knowledge, attitudes and practices regarding the implementation of caries risk assessment, particularly caries management by risk assessment (CAMBRA), in private dental practices. A 17 item survey was developed to evaluate dental hygienists' knowledge, attitudes and practices related to CAMBRA and perceived barriers to CAMBRA implementation in private dental practice. Surveys were mailed to a randomized sample of 1,000 dental hygienists licensed to practice in California. Responses were tabulated for each respondent, and the response frequency for each survey item was calculated. Respondents' comments to the open-ended question were compiled, according to themes. The response rate was 18%. Only 66% of the respondents were familiar with the term CAMBRA, although 89% agreed with its underlying principles of risk assessment. CAMBRA protocol had been implemented in 40% of the respondents' employment sites. Respondents disagreed that time (45%) and cost of products (68%) were barriers to implementation. Many did not know their employers' knowledge or attitudes about CAMBRA and its implementation, as evidenced by a "don't know" response range of 29 to 48% for the 4 relevant statements. Respondents' comments included both successes and barriers implementing CAMBRA. CAMBRA protocol has not been widely implemented in private practice, although the current data do not indicate insurmountable barriers. Broader dissemination may be feasible if dental hygienists would obtain more comprehensive knowledge of evidence-based risk assessment protocols and would assume a leadership role in implementing CAMBRA protocols and procedures in private dental practices.

    Dental caries is a sugar-dependent disease that damages tooth structure and, due to loss of mineral components, may eventually lead to cavitation. Dental caries is the most prevalent disease worldwide and is considered the most important burden of oral health. Conventional treatment methods (drill and fill) involve the use of rotary burs under local anaesthesia. The need for an electricity supply, expensive handpieces and highly trained dental health personnel may limit access to dental treatment, especially in underdeveloped regions.To overcome the limitations of conventional restorative treatment, the Atraumatic Restorative Treatment (ART) was developed, mainly for treating caries in children living in under-served areas of the world where resources and facilities such as electricity and trained manpower are limited. ART is a minimally invasive approach which involves removal of decayed tissue using hand instruments alone, usually without use of anaesthesia and electrically driven equipment, and restoration of the dental cavity with an adhesive material (glass ionomer cement (GIC), composite resins, resin-modified glass-ionomer cement (RM-GICs) and compomers). To assess the effects of Atraumatic Restorative Treatment (ART) compared with conventional treatment for managing dental caries lesions in the primary and permanent teeth of children and adults. Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 22 February 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2017, Issue 1), MEDLINE Ovid (1946 to 22 February 2017), Embase Ovid (1980 to 22 February 2017), LILACS BIREME Virtual Health Library (Latin American and Caribbean Health Science Information database; 1982 to 22 February 2017) and BBO BIREME Virtual Health Library (Bibliografia Brasileira de Odontologia; 1986 to 22 February 2017).

    My work at JPL for the SURF program began on June 11, 2012 with the Technical Facilities Management group (TFM). As well as TFM, I worked with Loan Pool and Metrology to help them out with various tasks. Unlike a lot of other interns, I did not have a specific project rather many different tasks to be completed over the course of the 10 weeks.The first task to be completed was to sort through old certification reports in 6 different boxes to locate reports that needed to be archived into a digital database. There were no reports within these boxes that needed to be archived but rather were to be shredded. The reports went back to the early 1980's and up to the early 2000's. I was looking for reports dated from 2002 to 2012

    The purpose is to report findings of a quality improvement (QI) project implemented at two hospital-based dental clinics that care for children with early childhood caries (ECC). We tested a disease management (DM) approach in children younger than age 60 months with ECC. After 30 months, for the 403 and 234 DM patients at Children's Hospital Boston (CHB) and Saint Joseph Hospital (SJH) who returned for at least two visits, rates of new cavitation, pain, and referrals to the OR were 26.1, 13.4 and 10.9% for CHB and 41.0, 7.3 and 14.9% for SJH. Rates of new cavitation, pain, and referrals to the OR for historical controls were 75.2, 21.7, and 20.9% for CHB and 71.3, 31.3, and 25.0% for SJH. A risk-based DM approach utilizing QI strategies to address ECC can be implemented into practice and has the potential to improve care and health outcomes.

    By arresting and preventing caries, SDF offers an alternate care path for patients for whom traditional restorative treatment is not immediately available. Current data from controlled clinical trials encompassing more than 3900 children, indicates that biannual application of SDF reduces progression of current and risk of subsequent caries. This commentary highlights the best evidence from systematic reviews and clinical trials for clinicians to consider the benefits, risks and limitations as they implement SDF therapy on young children.

    Tooth decay or cavities (dental caries) can have a significant impact on children's quality of life, causing pain, infection, and other problems in the oral environment. Good oral health is a fundamental element of good general health for children, yet dental caries is still prevalent among children in many countries. Dental caries is well-understood, and effective prevention is an attainable goal. Dental professionals should actively engage with communities--in particular, the underprivileged--to identify dental caries problems and implement appropriate and effective community oral health programs (COHPs) to improve oral health and reduce oral health inequalities. This paper discusses COHPs as well as the steps involved in caries prevention for children. These steps cannot ensure the success of every COHP, but they are helpful for developing, integrating, expanding, and enhancing them. The effectiveness of COHPs for the prevention of caries in children varies from country to country, according to cultural, social, economic, and health care settings. Careful consideration of the local situation is required when selecting the elements of COHPs.

  19. The future of technical knowledge management

    International Nuclear Information System (INIS)

    Kang, C.-S.

    2005-01-01

    The sustainable development of nuclear energy can only be achieved by establishing the global nuclear safety regime. The effective management of technical knowledge will become one of the issues and challenges in establishing the global nuclear safety. We have to develop the measures to identify the nature and scope of associated problems and to explore the cooperative international actions to resolve them. The future of its effective management will depend on how to optimize the transfer and deployment of the knowledge as well as how to maintain the knowledge base. In this presentation, two specific topics are discussed: sharing of the knowledge and preservation of the workforce. In sharing the knowledge, topics are assurance of free flow of safety-related R and D information from developed to developing countries and potential imposition of a strong trade agreement between nuclear exporting and importing countries to ensure the safety. In preserving the workforce, topics are development of the knowledge transfer system from this generation to the next like a forum of IYNC, enforcement of regional and international educational systems like ANENT and WNU for workforce development, and exploration of optimal mechanism in using retired workforce. The publication of the world-wide directory of nuclear professionals, aggressive implementation of the youth internship program and introduction of the international professional certification program are also discussed. The reformation of CNS as a more enforcing and binding agreement in keeping the safety along with the introduction of 'Global Nuclear Safety Treaty' could be an excellent mechanism of achieving an effective knowledge management and eventually enforcing the global safety regime. IAEA has always been the corroborator of maintaining high levels of nuclear safety through close international nuclear cooperation. These important roles of IAEA should continue to be emphasized more than ever in order to secure the

    Science.gov (United States)

    1984-06-01

    The use of effective preventive methods has produced good results in developed countries, where caries is declining and periodontal disease is probably getting no worse. There are special problems with prevention in developing countries, principally high periodontal disease prevalence, rising caries rates and lack of resources to deal with these problems. With appropriate assistance, much can still be accomplished in these developing countries. Depending on economic resources and disease patterns, the following procedures for oral disease prevention can be recommended. Priority order will vary from country to country, and national and local laws may also determine what procedures can or cannot be employed. Fluoridation of water supplies is the most effective action to prevent caries in communities where piped water supplies are in place. It is relatively cheap and does not depend on individual action. Where water fluoridation is not feasible, community-based alternatives are salt fluoridation, school-water fluoridation or supervised ingestion of fluoride supplements. Supervised mouthrinsing with fluoride solutions, usually in schools, is effective in fluoridated and non-fluoridated communities. Dentists or auxiliaries can also apply fluoride gels or solutions to the teeth of individual patients. The use of fluoride toothpastes is recommended wherever possible as a routine part of self care. All preventive activities have an educational component. Community leaders and others should be educated regarding the institution and maintenance of community preventive measures which affect them. Individual patients should be educated regarding their oral hygiene, use of fluoride, restriction of sugary snacks between meals and the necessity for regular dental visits when services are available. Dental health education of the public can be concentrated in special target groups such as expectant mothers. Because dental caries is a public health problem in many countries, public

    Polychlorinated biphenyls (PCBs) were important industrial chemicals featuring high thermal and chemical stability and low flammability. They were widely used as dielectric and thermal fluid in closed electro-technical applications (transformers, capacitors…) and also in numerous dispersive uses, ranking from auto-copying paper to sealant or coatings. During the 1960s, severe environmental consequences started becoming apparent. The stability of PCBs contributed to their persistence in the environment, their lipophilic character to bio-magnification. Fish-eating species seemed threatened in their existence. In Japan and in Taiwan, thousands of people consumed PCB-contaminated oil. The production of PCBs stopped completely during the 1980s. Usage could continue in closed applications only. In this paper, particular attention is given to two issues: the cleaning of PCB electric transformers and the potential impact of PCB-containing building materials. Other contributions will cover the management and treatment of PCB-contaminated soil, sludge or fly ash. The complete survey is being prepared by request of the Knowledge Center for Engineers and Professionals.

  3. DENTAL CARIES LEADING TO PREMATURE LOSS OF BABY TEETH- IMPLICATIONS AND MANAGEMENT

    Directory of Open Access Journals (Sweden)

    Rachana Bahuguna

    2011-12-01

    Full Text Available Dental caries is a destructive process causing decalcification of the tooth enamel and leading to continued destruction of enamel and dentin, and cavitation of the tooth. Dental caries can occur soon after eruption of the primary teeth, starting at 6 months of age. Primary teeth are present for a reason. One key reason is that they save space for the permanent tooth, which will erupt into its position when the deciduous / primary tooth is lost normally. If a primary tooth (baby or milk tooth, has to be removed early due to say, an abscess which is mostly a result of dental caries, a space maintainer may be recommended to save the space. If the space is not preserved, the other teeth may drift causing difficult to treat crowding and orthodontic problems. These "spacers" are placed temporarily, and are not permanent. They are removed when the new tooth (usually a bicuspid erupts or the abutment teeth get loose.

    Resin fissure sealants were introduced in child and adolescents dental health care in the late 1960s and early 1970s in Denmark. Since the initial experience was good, sealing of first molars’ occlusal surfaces shortly after tooth eruption was a regular caries preventive treatment in the 1980s....... Today, due to the improved dental health, resin sealants on occlusal surfaces are mainly used based on indication, i.e. surfaces with progressive enamel lesions. Previous studies indicate that progression of the occlusal caries lesion may be arrested with resin sealants provided that the sealant...

    Risk assessment is an essential component in the decision-making process for the correct prevention and management of dental caries. Multiple risk factors and indicators have been proposed as targets in the assessment of risk of future disease, varying sometimes based on the age group at which...... they are targeted. Multiple reviews and systematic reviews are available in the literature on this topic. This chapter focusses primarily on results of reviews based on longitudinal studies required to establish the accuracy of caries risk assessment.

    Salivary dysfunction in Sjögren disease can lead to serious and costly oral health complications. Clinical practice guidelines for caries prevention in Sjögren disease were developed to improve quality and consistency of care. A national panel of experts devised clinical questions in a Population, Intervention, Comparison, Outcomes format and included use of fluoride, salivary stimulants, antimicrobial agents, and nonfluoride remineralizing agents. The panel conducted a systematic search of the literature according to pre-established parameters. At least 2 members extracted the data, and the panel rated the strength of the recommendations by using a variation of grading of recommendations, assessment, development, and evaluation. After a Delphi consensus panel was conducted, the experts finalized the recommendations, with a minimum of 75% agreement required. Final recommendations for patients with Sjögren disease with dry mouth were as follows: topical fluoride should be used in all patients (strong); although no study results link improved salivary flow to caries prevention, the oral health community generally accepts that increasing saliva may contribute to decreased caries incidence, so increasing saliva through gustatory, masticatory, or pharmaceutical stimulation may be considered (weak); chlorhexidine administered as varnish, gel, or rinse may be considered (weak); and nonfluoride remineralizing agents may be considered as an adjunct therapy (moderate). The incidence of caries in patients with Sjögren disease can be reduced with the use of topical fluoride and other preventive strategies. Copyright © 2016 American Dental Association.

    Full Text Available Introduction: Evaluating a patients' risk is an essential primary step in the prevention of dental caries. Based on its results, different preventive strategies catering to patients' specific needs should be advised. Aim: To assess and compare the knowledge, attitude, and practice among dentists who are either attached with an institute or running a private practice or both in Delhi-National Capital Region regarding caries risk assessment (CRA and management. Materials and Methods: Knowledge, attitude, and practices of dentists' regarding CRA and management were assessed through a 30-item questionnaire. Data were analyzed using SPSS software 21.5. Frequencies were used to assess the demographic information, knowledge, attitude, and risk assessment practices. Results: Dental professionals with institutional attachment were better aware of the importance of CRA and practised it more frequently as compared to the dentists who were solely attached with a private practice. This attitude could be due to lack of time and inclination to treat more number of patients in a working day. Pedodontists were more aware than other specialists. Conclusions: There is a need to update knowledge regarding CRA and incorporate preventive practices in daily work schedule among dentists of all specialties.

    The aim of our study was the use of different types of isolation systems in the treatment of experimentally simulated dental caries that will allow to present additional comparative characteristic for morphological responses of the pulp.For realization of this purpose, 3 systems have been selected: UltraBlend (Ultradent), Biodentine (Septodont) and adhesive system Prime&Bond NT (Dentsply). The study was conducted at the laboratory of Alexander Natishvili Institute of Morphology. For this experiment, 12 male, 6 months of age rabbits were selected. There were created 3 experimental groups, each of which included 4 rabbits. Restoration of the teeth in experimental rabbits with Biodentine revealed sufficient physical properties enabling the operator most comfortably conduct his/her clinical activities: kneading, bringing into caries cavity, condensing and filling dental defect. Isolation of dentin by Biodentine doesn't contradict and/or reduce application of adhesive systems, which is also important for teeth restorations. Biodentine has optimal working time (final curing 10-12 minutes) enabling the operator to conduct maximal formation of material at the bottom of caries cavity.

    Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life, exposed root surfaces. The balance between pathological and protective factors influences the initiation and progression of caries. This interplay between factors underpins the classification of individuals and groups into caries risk categories, allowing an increasingly tailored approach to care. Dental caries is an unevenly distributed, preventable disease with considerable economic and quality-of-life burdens. The daily use of fluoride toothpaste is seen as the main reason for the overall decline of caries worldwide over recent decades. This Primer aims to provide a global overview of caries, acknowledging the historical era dominated by restoration of tooth decay by surgical means, but focuses on current, progressive and more holistic long-term, patient-centred, tooth-preserving preventive care.

    Concetti, Massimo; Cuccioletta, Roberto; Fedele, Lorenzo; Mercuri, Giampiero

    2009-01-01

    The management of technical plant for productivity and safety is generally a complex activity, particularly when many plants distributed in the territory are considered (i.e. the more and more frequent case of outsourced plants maintenance by specialized companies), granted quality and cost results are required (i.e. the case of some rather innovative contract solutions) and the technology involved is heterogeneous and innovative (i.e. electro-mechanical plants). In order to efficiently achieve the above aims an 'intelligent' maintenance-management system for the distant monitoring and controlling by a remote control center has been developed. The so-called GrAMS (granted availability management system) system is conceived to give to organizations involved in technical-industrial plants management the possibility to tend to a 'well-known availability' and 'zero-failures' management. In particular, this study deals with the diagnostic aspects and safety level of technical plants (such as elevators, thermo-technical plants, etc.), and with the involvement of ad hoc designed software analysis tools based on neural networks and reliability indicators. Part of the research dealing with the tele-maintenance intelligent system has been financed by the Italian High Institute for Safety (ISPESL) and led to the development of a pre-industrial prototype whose realization and testing is here described

    2018-01-04

    To prove that Caries Management by Risk Assessment (CAMBRA) can be successfully implemented in dental practices outside of the university setting, dentists in the San Francisco Bay Area (CA) were approached to participate in a Practice Based Research Network (PBRN) study. The overall goal of the CAMBRA-PBRN study was to recruit 30 dentists to perform a two-year study involving approximately 900 patients. Goal of the calibration study was to standardize and calibrate dentists potentially participating in the CAMBRA-PBRN study. To minimize inter-examiner variability in data collection, including classification of carious lesions and recording of existing restorations, participating dentists were trained and calibrated in accurate DMFS (decayed, missing, filled surfaces) charting. Dentists were also trained and calibrated to diagnose and differentiate between sound surfaces and non-cavitated caries lesions (International Caries Detection and Assessment - ICDAS scores 1 and 2) for posterior occlusal surfaces. Thirty dentists were calibrated to a single gold standard examiner (BJ) during 6 calibration sessions, between 2011 and 2014. Kappa statistics were used to determine inter-examiner reliability on 13 or more patients, aged 12-63 (average age 38 ± 15 years), per examiner during each session, resulting in 94 patient encounters over the course of all 6 sessions. To participate in the main study, examiners needed to achieve a minimum required kappa of 0.75. During the calibration process, examiners scored between 1036 and 2220 tooth surfaces. The kappa values (unweighted kappa) of the participating dentists compared to the gold standard examiner ranged from 0.75 to 0.90, with an average kappa of 0.84 ± 0.03. 90% of the examiners achieved overall kappa values above 0.8. However, separate reliability for assessment of non-cavitated lesions, as in other studies, was lower (0.55 ± 0.15). Multiple subcategories were evaluated. All dentists reached sufficient

  11. Caries detection using light-based diagnostic tools.

    Science.gov (United States)

    Rechmann, Peter; Rechmann, Beate M T; Featherstone, John D B

    2012-09-01

    Modern caries treatment concepts like caries management by risk assessment--CAMBRA--entail diagnosing early caries lesions in a precavitated stage to make it possible to reverse the caries process with remineralization and bacteria reduction efforts. Newer, sensitive caries diagnostic tools can serve not only for early detection but also for monitoring of caries lesions to confirm the success of prevention and remineralization efforts. This article describes light-based caries diagnostic tools, with emphasis on fluorescence-based techniques, and compares the most common available fluorescence-based tools with a standardized visual caries inspection system-the International Caries Detection and Assessment System (ICDAS II). Fluorescence tools that provide high-resolution fluorescence pictures are likely to provide more reliable scores than fluorescence devices that assess via a single spot. The better visibility of the high-resolution fluorescence imaging could prevent unnecessary operative interventions.

    Key, K.T.; Fox, R.D.

    1994-02-01

    The tasks performed in the Remedial Investigation/Feasibility Study (RI/FS) work plan for each Hanford Site operable unit must meet the requirements of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement, Ecology et. al 1992). An extensive amount of data will be generated in the evaluation and remediation of hazardous waste sites at the Site. The data must be of sufficient quality, as they will be used to evaluate the need, select the method(s), and support the full remediation of the waste sites as stipulated in the Tri-Party Agreement. In particular, a data management plan (DMP) is to be included in an RI/FS work plan for managing the technical data obtained during the characterization of an operable unit, as well as other data related to the study of the operable unit. Resource Conservation and Recovery Act of 1976 (RCRA) sites are involved in the operable unit. Thus, the data management activities for the operable unit should be applied consistently to RCRA sites in the operable unit as well. This DMP provides common direction for managing-the environmental technical data of all defined operable units at the Hanford Site during the RI/FS activities. Details specific to an operable unit will be included in the actual work plan of that operable unit

    2012-11-01

    Recent increases in caries prevalence in young children throughout the world highlight the need for a simple but effective infant oral care programme. This programme needs to include a medical disease prevention management model with an early establishment of a dental home and a treatment approach based on individual patient risk. This article presents an updated approach with practical forms and tools based on the principles of caries management by risk assessment, CAMBRA. This method will aid the general practitioner to develop and maintain a comprehensive protocol adequate for infant and young children oral care visits. Perinatal oral health is vitally important in preventing early childhood caries (ECC) in young children. Providing dental treatment to expectant mothers and their young children in a 'dual parallel track' is an effective innovative strategy and an efficient practice builder. It promotes prevention rather than intervention, and this may be the best way to achieve long-lasting oral health for young patients. General dental practice can adopt easy protocols that will promote early preventive visits and anticipatory guidance/counselling rather than waiting for the need for restorative treatment.

    2016-07-01

    Full Text Available General practitioners must constantly face challenges imposed by their profession when performing interventions that are necessary for their patients. Many of these interventions not only require proper use of theoretical knowledge, but also putting into practice non-technical and psychomotor skills developed through professional training. Given the specific characteristics of each patient, the clinical setting in the which procedure takes place and the limited skills of the professional, the management of the airway of a patient with trauma injuries in the emergency room represents a major challenge for physicians.

    Full Text Available In 1999 and 2000, the Masaryk Institute of Advanced studies of CTU in Prague launched a study of the efficiency of human resource management in Czech enterprises, with emphasis on technically educated managers. About 85 managers, each responsible for 5-250 employees assessed their own HRM activities and attitudes and those of their firm. The following aspects were analysed: evaluating individual management areas, assessing the general management standard of the given company, awareness of the company's personnel management policy, manager's own contribution to formulating the company's personnel management strategy, developing job descriptions, using professional methods of employee selection, promoting employees to the status of manager, periodic assessment of employees, training of staff responsible for assessment, employee remuneration and other motivation tools, etc. Results and data analysis are given in the paper. The managers of the Czech companies reviewed are still involved mainly in operating management, and devote limited time to the conceptual work needed in order to formulate an integral company policy in the area of personnel management. On the basis of this analysis, further training for managers with technical education will be designed and organised by the Masaryk Institute of Advanced Studies.

    1992-01-01

    The Department of Energy/Office of Civilian Radioactive waste Management (DOE/OCRWM) is responsible for the characterization of Yucca Mountain, Nevada, to determine its potential as a site of a high-level radioactive waste repository. The characterization of Yucca Mountain encompasses many diverse investigations, both onsite and in laboratories across the country. Investigations are being conducted of the geology, hydrology, mineralogy, paleoclimate, geotechnical properties, and archeology of the area, to name a few. Effective program management requires that data from site investigations be processed, interpreted and disseminated in a timely manner to support model development and validation, repository design, and performance assessment. The Program must also meet regulatory requirements for making the technical data accessible to a variety of external users throughout the life of the Project. Finally, the DOE/OCRWM must make available the data or its description and access location available for use in support of the license application and supporting documentation. To accomplish these objectives, scientific and engineering data, generated by site characterization activities, and technical data, generated by environmental and socioeconomic impact assessment activities, must be systematically identified, cataloged, stored and disseminated in a controlled manner

    Kent, Peter

    2008-01-01

    Effective space systems engineering (SSE) is conducted in a fully electronic manner. Competitive hardware, software, and system designs are created in a totally digital environment that enables rapid product design and manufacturing cycles, as well as a multitude of techniques such as modeling, simulation, and lean manufacturing that significantly reduce the lifecycle cost of systems. Because the SSE lifecycle depends on the digital environment, managing the enormous volumes of technical data needed to describe, build, deploy, and operate systems is a critical factor in the success of a project. This chapter presents the key aspects of Technical Data Management (TDM) within the SSE process. It is written from the perspective of the System Engineer tasked with establishing the TDM process and infrastructure for a major project. Additional perspectives are reflected from the point of view of the engineers on the project who work within the digital engineering environment established by the TDM toolset and infrastructure, and from the point of view of the contactors who interface via the TDM infrastructure. Table 17.1 lists the TDM process as it relates to SSE.

    2008-07-01

    Approximately two years after promulgation of the Energy Employees Occupational Illness Compensation Program Act, the National Institute for Occupational Safety and Health Office of Compensation and Analysis Support selected a contractor team to perform many aspects of the radiation dose reconstruction process. The project scope and schedule necessitated the development of an organization involving a comparatively large number of health physicists. From the initial stages, there were many technical and managerial challenges that required continuous planning, integration, and conflict resolution. This paper identifies those challenges and describes the resolutions and lessons learned. These insights are hopefully useful to managers of similar scientific projects, especially those requiring significant data, technical methods, and calculations. The most complex challenge has been to complete defensible, individualized dose reconstructions that support timely compensation decisions at an acceptable production level. Adherence to applying claimant-favorable and transparent science consistent with the requirements of the Act has been the key to establishing credibility, which is essential to this large and complex project involving tens of thousands of individual stakeholders. The initial challenges included garnering sufficient and capable scientific staff, developing an effective infrastructure, establishing necessary methods and procedures, and integrating activities to ensure consistent, quality products. The continuing challenges include maintaining the project focus on recommending a compensation determination (rather than generating an accurate dose reconstruction), managing the associated very large data and information management challenges, and ensuring quality control and assurance in the presence of an evolving infrastructure. The lessons learned concern project credibility, claimant favorability, project priorities, quality and consistency, and critical

    In spite of considerable spending on research and technical development, the management of nuclear wastes continues to be a difficult issue in public decision making. The nuclear industry says that it has safe solutions for the ultimate disposal of nuclear wastes, but the message has not really got through to the public at large. Although communications problems reflect the general stigmatization of nuclear power, there are obvious issues in safety and performance assessment of nuclear waste disposal which evade scientific resolution. Any scientist is concerned for his personal credibility must respect the rules and limits of scientific practice, but the intriguing question is whether he would not do better to address the layman's worries about radioactive substances? The discussion in this paper points out the intricacies of the distinction between scientific proof and judgement, with emphasis on safety assessment for nuclear waste disposal. Who are the final arbitrators? In a democratic society it is probably those who vote.Building confidence in expert judgements is a challenge for waste managers and scientists. The media may create their own 'experts', whose only necessary credential is the trust of their audience, but scientific judgements must stand the test of time.'Confidence building' is currently a key word on the whole nuclear waste management scene, and confidence in science and scientists is certainly needed for any progress towards practical implementation of plans. The means for building confidence in the decision-making process are probably different from those applied for science and scientists. (author)

    treatment and prevention of dental caries have been introduced over the past century. The use of chlorhexidine in caries prevention has been referred to as a nonsurgical management of dental caries and has represented the modern medical model of caries treatment. However, there is a lack of consensus on evidence-based treatment protocols and controversy regarding the role of chlorhexidine in caries prevention among dental educators and clinicians. There is a need to standardize guidelines to optimize evidence-based non-surgical disease management to provide appropriate care. This paper reviewed the literature on the effectiveness of different modes of chlorhexidine delivery for caries prevention and provides guidelines for chlorhexidine use in caries management. A literature search was conducted using the PubMed and Evidence-Based Medicine Reviews databases and the keywords "chlorhexidine" and "caries", limiting the search to "humans", "reviews" and "English". Based on the published reviews, it was concluded that chlorhexidine rinses, gels and varnishes or combinations of these items with fluoride have variable effects. Additionally, the sparse clinical data that was reported weakens the conclusions. Due to the current lack of evidence on long-term clinical outcomes and reported side effects, chlorhexidine rinse, which is currently the only treatment mode available in the US, should not be recommended for caries prevention. Clinical evidence on gels and varnishes is also inconclusive. For the treatment of dental caries, there are alternative evidence-based prevention methods available, such as fluoride applications, diet modifications and good oral hygiene practices.

    Prevalence and distribution of dental caries in medieval Korean society were evaluated. Two thousand and nine hundred teeth samples of 126 individuals collected from 16th to 18th century Korean tombs. Preservation status of sample was good. The prevalence of ante- and postmortem tooth loss was 4.4% and 14.2%, respectively. The total caries prevalence was 3.9%. The tooth surface most frequently affected by dental caries was occlusal (4.5%), followed by approximal (2.1%), buccal (1.5%), and lingual (1.1%) surfaces. The prevalence of dental caries in Joseon Dynasty skeleton collection was lower than have been found in other collections of similar chronology. The low consumption of refined sugar in medieval Korean society might be a possible explanation, though the technical limitations inherent in such comparison studies preclude definitive conclusions. 2010 Elsevier Ltd.

    Full Text Available Dental caries is one of the most common diseases in humans. In modern times, it has reached epidemic proportions. Dental caries is an infectious microbiologic disease of the teeth that results in localized dissolution and destruction of the calcified tissue. Dental caries is a mulitifactorial disease, which is caused by host, agent, and environmental factors. The time factor is important for the development and progression of dental caries. A wide group of microorganisms are identified from carious lesions of which S. mutans , Lactobacillus acidophilus , and Actinomyces viscosus are the main pathogenic species involved in the initiation and development of dental caries. In India, surveys done on school children showed caries prevalence of approximately 58%. Surveys among the U.S. population showed an incidence of 45.3% in children and 93.8% in adults with either past or present coronal caries. Huge amounts of money and time are spent in treating dental caries. Hence, the prevention and control of dental caries is the main aim of public health, eventually the ultimate objective of public health is the elimination of the disease itself. Recently, dental caries vaccines have been developed for the prevention of dental caries. These dental caries vaccines are still in the early stages.

    Promotion of sound dietary practices is an essential component of caries management, along with fluoride exposure and oral hygiene practices. Scientific discoveries have lead to better understanding of the caries process, the ever-expanding food supply, and the interaction between the two. Fermentable carbohydrates interact dynamically with oral bacteria and saliva, and these foods will continue to be a major part of a healthful diet. Dental health professionals can serve their patients and the public by providing comprehensive oral health care and by promoting lifestyle behaviors to improve oral and general health within the time constraints of their practice. Dietary advice given should not contradict general health principles when providing practical guidance to reduce caries risk. The following principles should guide messages: * Encourage balanced diets based on moderation and variety as depicted by the Food Guide Pyramid and the Dietary Guidelines for Americans to provide a sound approach. Avoid references to "bad" foods and focus on "good" diets that include a variety of foods. * Give examples of how combining and sequencing foods can enhance mastication, saliva production, and oral clearance at each eating occasion. Combining dairy foods with sugary foods, raw foods with cooked, and protein-rich foods with acidogenic foods are all good examples. Suggest that eating and drinking be followed by cariostatic foods such as xylitol chewing gum. * Drink water to satisfy thirst and hydration needs as often as possible. Restrict consumption of sweetened beverages to meal and snack times when they can be combined with other cariostatic foods. * When a patient reports excessive dietary intake of a fermentable carbohydrate to the point of displacing other important foods in the diet, identify alternatives that will help the patient maintain or achieve a healthy body weight, oral health status, and a nutrient-dense intake.

    In addition to the current NASA manned programs, the maturation of Space Station and the introduction of the Space Exploration programs are anticipated to add substantially to the number and variety of data and documentation at NASA Johnson Space Center (JSC). This growth in the next decade has been estimated at five to ten fold compared to the current numbers. There will be an increased requirement for the tracking and currency of space program data and documents with National pressures to realize economic benefits from the research and technological developments of space programs. From a global perspective the demand for NASA's technical data and documentation is anticipated to increase at local, national, and international levels. The primary users will be government, industry, and academia. In our present national strategy, NASA's research and technology will assume a great role in the revitalization of the economy and gaining international competitiveness. Thus, greater demand will be placed on NASA's data and documentation resources. In this paper the strategies and procedures developed by DDMS, Inc., to accommodate the present and future information utilization needs are presented. The DDMS, Inc., strategies and procedures rely on understanding user requirements, library management issues, and technological applications for acquiring, searching, storing, and retrieving specific information accurately and quickly. The proposed approach responds to changing customer requirements and product deliveries. The unique features of the proposed strategy include: (1) To establish customer driven data and documentation management through an innovative and unique methods to identify needs and requirements. (2) To implement a structured process which responds to user needs, aimed at minimizing costs and maximizing services, resulting in increased productivity. (3) To provide a process of standardization of services and procedures. This standardization is the central

    In this paper, we explain the conceptual background to non-technical skills and show how they can influence job performance in anaesthesia. We then describe the taxonomy of anaesthetists' non-technical skills (ANTS) and related systems, such as ANTS-AP for anaesthetic practitioners. We discuss the training courses that have been designed to teach these non-technical skills, which are called crew resource management (CRM), crisis resource management (CRM) or crisis avoidance resource management (CARMA). Finally, we discuss the application of non-technical skills assessment systems. Copyright © 2015 Elsevier Ltd. All rights reserved.

  18. Leveraging Independent Management and Chief Engineer Hierarchy: Vertically and Horizontally-Derived Technical Authority Value

    Science.gov (United States)

    Barley, Bryan; Newhouse, Marilyn

    2012-01-01

    In the development of complex spacecraft missions, project management authority is usually extended hierarchically from NASA's highest agency levels down to the implementing institution's project team level, through both the center and the program. In parallel with management authority, NASA utilizes a complementary, but independent, hierarchy of technical authority (TA) that extends from the agency level to the project, again, through both the center and the program. The chief engineers (CEs) who serve in this technical authority capacity oversee and report on the technical status and ensure sound engineering practices, controls, and management of the projects and programs. At the lowest level, implementing institutions assign project CEs to technically engage projects, lead development teams, and ensure sound technical principles, processes, and issue resolution. At the middle level, programs and centers independently use CEs to ensure the technical success of their projects and programs. At the agency level, NASA's mission directorate CEs maintain technical cognizance over every program and project in their directorate and advise directorate management on the technical, cost, schedule, and programmatic health of each. As part of this vertically-extended CE team, a program level CE manages a continually varying balance between penetration depth and breadth across his or her assigned missions. Teamwork issues and information integration become critical for management at all levels to ensure value-added use of both the synergy available between CEs at the various agency levels, and the independence of the technical authority at each organization.

  19. Managing knowledge in technical and scientific support organizations

    2007-01-01

    Full text: In an introduction, the issues in knowledge management regarding licensing and supervision authorities as well as technical and scientific support organisations (TSO's) will be discussed. Although in general many of these issues are quite similar across organizations in the nuclear field, specific questions arise according to the knowledge management policies in regulation and supervision, as will be demonstrated by discussing the results of a recent workshop on human resource management in regulation and safety. With the need for managing knowledge in regulation and safety, a further field of supporting authorities has been opened to TSO's. As a prerequisite, a good knowledge on knowledge management methods and tools has to be acquired by a TSO, preferably by installing an own knowledge management system, thus gaining the indispensable practical experience. Driven by the ongoing demographic change, some TSO's have started early with the implementation of knowledge management practices in their own organizations. Three examples will be presented in the paper concerning knowledge management in safety and regulation, illustrating the efforts undertaken at GRS, the BMU (German Federal Ministry of Environment, Nature Preservation and Reactor Safety), and the TUV-SUD. At GRS, knowledge management started by specifying the goals of maintaining knowledge, particularly of retiring experts, and transferring this knowledge to the next generation. In addition, the knowledge management methods should become an integral part of every day's work, thus ensuring the sustainability of the effort. Initially, a basis for handling and distributing information and documents was provided by setting up a portal with integrated document management capabilities. In a next step, work was concentrated on the core business process, namely project work. This has been achieved by providing an own portal site for each project where all information pertinent to the project such as

    With the deregulation of energy market and the appeal for environment protection, more and more distributed generation (DG) is embedded in the distribution network. However the approach of connecting DG in most cases is based on a so-called ''fit and forget'' policy and the capacity of DG is limited rigidly by distribution network operator (DNO) to avoid the negative effects of high level penetration. Therefore active management (AM) is put forward as an effective method to network reinforcement for the connection and operation of DG. In this paper, the concept and principle of AM are introduced, and several indices are proposed to evaluate both technical and economic impacts of AM on distribution network with DG. To simplify the simulation fuzzy C-means clustering (FCM) algorithm is introduced. The test results on a sample system represent that AM will lead to decrease of power generation of DG, but it can reduce energy losses and improve voltage profile effectively. Furthermore, AM will take great economic incentives to DG developer as well as DNO with reasonable policy. (author)

    Dental caries affects the majority of the Danish population. Its aetiology is multi-factorial, but a pH-induced change in the homeostasis of the oral biofilm leading to overgrowth of acid-tolerating bacteria is a key event. A non-invasive concept for prevention and management is emerging based on the common risk factor approach. There is strong evidence that tooth brushing twice a day with fluoridated toothpaste is the most cost-effective way to prevent and control caries development. Physicians need to consider that a number of drugs may affect the saliva flow rate, which increases the caries risk.

    Anaesthesiologists may occasionally manage life-threatening operating room (OR) emergencies. Managing OR emergencies implies real-time analysis of often complicated situations, prompt medical knowledge retrieval, coordinated teamwork and effective decision making in stressful settings. Checklists are recommended to improve performance and reduce the risk of medical errors. This study aimed to assess the usefulness of the French Society of Anaesthesia and Intensive Care's (SFAR) "Malignant Hyperthermia" (MH) checklist on a simulated episode of MH crisis and management thereof by registered anesthesiologists. Twenty-four anaesthesiologists were allocated to 2 groups (checklist and control). Their technical performance in adherence with the SFAR guidelines was assessed by a 30-point score and their non-technical performance was assessed by the Anaesthetists' Non-Technical Skills (ANTS) score. Every task completion was assessed independently. Data are shown as median (first-third quartiles). Anaesthesiologists in the checklist group had higher technical performance scores (24/30 (21.5-25) vs 18/30 (15.5-19.5), P=0.002) and ANTS scores (56.5/60 (47.5-58) vs 48.5/60 (41-50.5), P=0.024). They administered the complete initial dose of dantrolene (2mg/kg) more quickly (15.7 minutes [13.9-18.3] vs 22.4 minutes [18.6-25]) than the control group (P=0.017). However, anaesthesiologists deemed the usability of the checklist to be perfectible. Registered anaesthesiologists' use of the MH checklist during a simulation session widely improved their adherence to guidelines and non-technical skills. This study strongly suggests the benefit of checklist tools for emergency management. Notwithstanding, better awareness and training for anaesthesiologists could further improve the use of this tool.

    Managing the nuclear arsenals (whether strategic or non-strategic ones) belonging to States that possess nuclear weapons is quintessentially based on the objective of maintaining security, safety and the reliability of their weapons. Since the early stages of military nuclear armaments, it has hinged on an approach that has been altogether scientific, technical and industrial, where nuclear tests have played a key role in acquiring and checking knowledge, while advancing the research and development of new weapons. It has experienced important evolutions, particularly linked to the interruption of nuclear tests since the early 1990's, and to the gradual multilateral evolution towards the total banning of such tests, enforced thanks to moratorium agreements and later by the rounds of talks leading to the Comprehensive Test Ban Treaty (CTBT), its adoption and opening for signature in September 1996. The situation of de facto nuclear states is a different one, in that their strategic posture and the development of their arsenals are placed in specific regional contexts; yet, compared with the five nuclear weapons States according to the definition of the Non-Proliferation Treaty (NPT), their objectives in terms of reliability, safety and security are, of necessity, of the same nature, even though the technological capabilities placed at their disposal to meet their goals may vary considerably from one country to the next. One determining context is the ban on nuclear weapon tests. As decades went by, four successive treaties were signed: PTBT (1963), TTBT (1974), PNET (1976), CTBT (1996). Even though a complete, legally binding test ban still remains to be fully implemented, for more than ten years, there has existed a political norm of renunciation of testing, and a quasi-universal one too. Indeed the CTBT has had, and will continue to have, more remarkable results than the previous treaties, and it is bound to impose further serious constraints on the Stockpile

    Dental caries is one of the most common infectious diseases. Of the oral bacteria, mutans streptococci, such as Streptococcus mutans and S. sobrinus, are considered to be causative agents of dental caries in humans. There have been numerous studies of the immunology of mutans streptococci. To control dental caries, dental caries vaccines have been produced using various cell-surface antigens of these organisms. Progress in recombinant DNA technology and peptide synthesis has been applied to the development of recombinant and synthetic peptide vaccines to control dental caries. Significant protective effects against dental caries have been shown in experimental animals, such as mice, rats and monkeys, which have been subcutaneously, orally, or intranasally immunized with these antigens. Only a few studies, however, have examined the efficacy of dental caries vaccines in humans. Recently, local passive immunization using murine monoclonal antibodies, transgenic plant antibodies, egg-yolk antibodies, and bovine milk antibodies to antigens of mutans streptococci have been used to control the colonization of the organisms and the induction of dental caries in human. Such immunization procedures may be a safer approach for controlling human dental caries than active immunization.

    Full Text Available Objective. The aim of this research was to assess the efficiency of different multifactor models in caries prediction. Material and methods. Data from the questionnaire and objective examination of 109 examinees was entered into the Cariogram, Previser and Caries-Risk Assessment Tool (CAT multifactor risk assessment models. Caries risk was assessed with the help of all three models for each patient, classifying them as low, medium or high-risk patients. The development of new caries lesions over a period of three years [Decay Missing Filled Tooth (DMFT increment = difference between Decay Missing Filled Tooth Surface (DMFTS index at baseline and follow up], provided for examination of the predictive capacity concerning different multifactor models. Results. The data gathered showed that different multifactor risk assessment models give significantly different results (Friedman test: Chi square = 100.073, p=0.000. Cariogram is the model which identified the majority of examinees as medium risk patients (70%. The other two models were more radical in risk assessment, giving more unfavorable risk –profiles for patients. In only 12% of the patients did the three multifactor models assess the risk in the same way. Previser and CAT gave the same results in 63% of cases – the Wilcoxon test showed that there is no statistically significant difference in caries risk assessment between these two models (Z = -1.805, p=0.071. Conclusions. Evaluation of three different multifactor caries risk assessment models (Cariogram, PreViser and CAT showed that only the Cariogram can successfully predict new caries development in 12-year-old Bosnian children.

    The technical status of the old U.S. mailine program for high level radioactive nuclear waste management, and the newly-developing program for disposal of unreprocessed spent fuel was assessed. The method of long term containment for both of these waste forms is considered to be deep geologic isolation in bedded salt. Each major component of both waste management systems is analyzed in terms of its scientific feasibility, technical achievability and engineering achievability. The resulting matrix leads to a systematic identification of major unresolved technical or scientific questions and/or gaps in these programs.

    International Nuclear Information System (INIS)

    Reese, Sven H.; Brast, Gerhard; Schoeckle, Friedrich

    2009-01-01

    The publication explains, by means of specific measures, the management of aging in technical facilities as practiced in the plants of E.ON Kernkraft GmbH. First, the historical background is outlined and the reasons for introducing management of aging in order to limit and control factors influencing the lifetime of nuclear power plants are described. This is followed by a definition of management of aging in important safety-related facilities as against lifetime management of technical systems relevant to plant availability. This is the context in which the scope of the survey of continuous management of aging is defined in respect of physical aging. A classification is then made in accordance with the staggered requirements to be met in the quality of technical facilities. On the basis of the quality to be assured, the different component groups are assigned corresponding operational measures and explained. These continuous measures extend from failure-oriented maintenance to preventive maintenance to the integrity concept for technical installations. To document the findings and evaluate the effectiveness of the measures taken, the integration of the process is described and reference is made to continuous optimization according to PDCA principles. The explicit introduction of the process of management of aging creates a platform which allows a documentation to be accumulated of the manifold and comprehensive measures taken to control phenomena of aging in technical installations.

  8. Industrial management- control and profit a technical approach

    CERN Document Server

    Halevi, Gideon

    2014-01-01

    This volume presents controlling tools for management in order to be in a position to communicate with control engineers concerning technological decisions. The main objective of manufacturing management is to make profit. However, in traditional manufacturing systems none of the separate stages in the process support this objective. Management is not expert in any of these stages, and therefore is dependent on specific experts at each stage and must follow their decisions. Each stage has its own first priority which is not profit and cost. This means that management does not have real control over these functional stages, nor over the process as a whole. This book presents controlling tools for management in order to allow them to communicate better with the experts of the particular manufacturing stages to reach better results and higher profits. It is shown that most enterprises can improve their efficiency rate by between 25 and 60% by using the tools developed here.

    Awareness of design smells - indicators of common design problems - helps developers or software engineers understand mistakes made while designing, what design principles were overlooked or misapplied, and what principles need to be applied properly to address those smells through refactoring. Developers and software engineers may ""know"" principles and patterns, but are not aware of the ""smells"" that exist in their design because of wrong or mis-application of principles or patterns. These smells tend to contribute heavily to technical debt - further time owed to fix projects thought to b

  17. Radiation caries - an evil eye of radiotherapy

    International Nuclear Information System (INIS)

    Lakshman, Anusha Rangare

    2013-01-01

    Although radiotherapy plays an important role in the management of patients with head and neck cancer, it is also associated with several undesired side effects such as radiation caries which is a common, yet serious, complication. The radiotherapy field of exposure frequently includes the salivary glands, oral mucosa, and jaws, thus, leading to various side effects including hyposalivation, mucositis, and taste loss. Irradiated patients are also at increased risk for the development of a rapid, rampant carious process known as radiation caries. Lesions tend to develop four weeks after completion of radiotherapy and affect atypical areas of teeth, such as the lingual surface, incisal edges, and cusp tips. The aim of this paper is to review the clinical features, prevention and management of radiation caries. (author)

    Gradisar, D.; Freeland, K.R.

    1996-01-01

    Nuklearna Elektrarna Krsko (NEK) was constructed as a turnkey plant, entering commercial service in 1981. NEK operates the plant with a unique management philosophy which has adapted well to the demands of today's business environment. Contributing to this success has been the NEK Management Information System (MIS) that has assisted NEK in 'making more with less'. A key element of the MIS is the Technical Document system, which includes the DCM (Document Control Module) and QRM (Quality Records Management), enabling the successful retrofit of the existing document management and 'turnkey' plant records environment to a new, thoroughly integrated system controlling plant operation and configuration management. The system integrates the Engineering Equipment and Configuration Management data systems, providing immediate, realtime cross-reference of plant equipment and plant modifications with technical documentation.

    To develop a unique simulation-based assessment using a laparoscopic inferior vena cava (IVC) injury scenario that allows for the safe assessment of urology resident's technical and nontechnical skills, and investigate the effect of personality traits performance in a surgical crisis. Urology residents from our institution were recruited to participate in a simulation-based training laparoscopic nephrectomy exercise. Residents completed demographic and multidimensional personality questionnaires and were instructed to play the role of staff urologist. A vasovagal response to pneumoperitoneum and an IVC injury event were scripted into the scenario. Technical and nontechnical skills were assessed by expert laparoscopic surgeons using validated tools (task checklist, GOALS, and NOTSS). Ten junior and five senior urology residents participated. Five residents were unable to complete the exercise safely. Senior residents outperformed juniors on technical (checklist score 15.1 vs 9.9, p Technical performance scores correlated with NOTSS scores (p technical performance (p technical score (p = 0.03) and pass/fail rating (p = 0.04). Resident level of training and laparoscopic experience correlated with technical performance during a simulation-based laparoscopic IVC injury crisis management scenario, as well as multiple domains of nontechnical performance. Personality traits of our surgical residents are similar and did not predict technical skill. Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc.

    2001-12-14

    This article focuses on the management lessons learned from disasters involving hazardous materials, which occurred in Quebec, Canada, between 1988 and 1995. The findings of the previous case studies of Canadian and some other disasters are considered as well. Both technical and sociopolitical issues on the disaster management are contemplated from the viewpoint of complexity and uncertainty. A distinction is made between the two concepts through specific examples. In addition, two types of uncertainty, first and second-level, are differentiated. The relationship between technical and sociopolitical issues of such management are then illustrated, and the salience of efficient disaster risk communication between technical specialists and the public for bridging the gap existing between these two types of issues is shown.

  14. Technical considerations and policy requirements for plutonium management

    International Nuclear Information System (INIS)

    Christensen, D.C.; Dinehart, S.M.; Yarbro, S.L.

    1996-01-01

    The goals for plutonium management have changed dramatically over the past few years. Today, the challenge is focused on isolating plutonium from the environment and preparing it for permanent disposition. In parallel, the requirements for managing plutonium are rapidly changing. For example, there is a significant increase in public awareness on how facilities operate, increased attention to environmental safety and health (ES and H) concerns, greater interest in minimizing waste, more emphasis on protecting material from theft, providing materials for international inspection, and a resurgence of interest in using plutonium as an energy source. Of highest concern, in the immediate future, is protecting plutonium from theft or diversion, while the national policy on disposition is debated. These expanded requirements are causing a broadening of responsibilities within the Department of Energy (DOE) to include at least seven organizations. An unavoidable consequence is the divergence in approach and short-term goals for managing similar materials within each organization. The technology base does exist, properly, safely, and cost effectively to extract plutonium from excess weapons, residues, waste, and contaminated equipment and facilities, and to properly stabilize it. Extracting the plutonium enables it to be easily inventoried, packaged, and managed to minimize the risk of theft and diversion. Discarding excess plutonium does not sufficient reduce the risk of diversion, and as a result, long-term containment of plutonium from the environment may not be able to be proven to the satisfaction of the public

For example, there is a significant increase in public awareness on how facilities operate, increased attention to environmental safety and health (ES and H) concerns, greater interest in minimizing waste, more emphasis on protecting material from theft, providing materials for international inspection, and a resurgence of interest in using plutonium as an energy source. Of highest concern, in the immediate future, is protecting plutonium from theft or diversion, while the national policy on disposition is debated. These expanded requirements are causing a broadening of responsibilities within the Department of Energy (DOE) to include at least seven organizations. An unavoidable consequence is the divergence in approach and short-term goals for managing similar materials within each organization. The technology base does exist, properly, safely, and cost effectively to extract plutonium from excess weapons, residues, waste, and contaminated equipment and facilities, and to properly stabilize it. Extracting the plutonium enables it to be easily inventoried, packaged, and managed to minimize the risk of theft and diversion. Discarding excess plutonium does not sufficiently reduce the risk of diversion, and as a result, long-term containment of plutonium from the environment may not be able to be proven to the satisfaction of the public

  20. Dental caries: Therapeutic possibilities

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Contemporary tendencies in dentistry are based on the concept of maximal protection of healthy tooth tissues. Caries removal has been done traditionally with mechanical rotary instruments that are fast and precise. However, conventional cavity preparation has potential adverse effects to the pulp due to heat, pressure and vibrations. Moreover, drilling often causes pain and requires local anaesthesia, and these procedures are frequently perceived as unpleasant. Etiology, development and prevention of dental caries are better understood today and new restorative materials that bond micromechanically and/or chemically to dental tissues have been introduced. Thus, development of a new, less destructive caries removal technique is allowed. In the last decades, many alternative methods have been introduced in an attempt to replace rotary instruments. These are claimed to be efficient and selective for diseased tissues and to offer comfortable treatment to the patients. New methods include air abrasion, air polishing, ultrasonic, polymer burs, enzymes, systems for chemo-mechanical caries removal, and lasers. The aim of this paper was to discuss various caries removal techniques and possibilities of their use in clinical practice. Based on the literature review it can be concluded that none of the new caries removal methods can completely replace conventional rotary instruments.

    Managerial capacity builds over the years and the accumulated knowledge and practice affect the outcome of the period that follows, with long-run/permanent effects on inefficiency. Therefore predictions of the influence of managerial capacity on the time-varying inefficiency, regularly estimated as overall efficiency, may be biased. This study analysed the influence of farm management practices on both the persistent and overall efficiency. The empirical application in the study was pig farms...

    Several systemic diseases and their medical treatment may predispose the development of aggressive dental caries. Head and neck radiotherapy, chemotherapy, Sjögren's syndrome and long-standing treatment with drugs that induce hyposalivation are some of these conditions. The aim of this article is to describe the clinical features of five patients who developed chronic graft-versus-host-disease (cGVHD) as a complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and, in spite of close dental follow-up, subsequently developed rampant caries. In these cases, the restorations showed early failure and the caries still progressed until generalized teeth destruction. The majority of the teeth therefore had to be extracted due to advanced dental caries and rapid clinical progression. Herein the term "cGVHD-related caries" is proposed to describe this under-recognized complication of cancer treatment that may evolve in allo-HSCT recipients that develop cGVHD. This condition is poorly recognized in the literature and may represent the final result of the clustering of oral complications in cGVHD patients, including mucositis, oral pain, hyposalivation, taste loss and oral infections, leading to rampant caries due to impaired oral hygiene and increased intake of highly cariogenic food. Consequently, the knowledge of this oral complication should improve the medical and dental management of cGVHD oral manifestations and improve the quality of life of patients with this post allo-HSCT complication.

    2014-05-01

    As from the first of July 2013, Croatia became a EU member country and therefore has to comply with all the EU-rules (the "acquis") as defined in the European Council in Copenhagen in 1993. One of the aspects of this acquis is the protection and conservation of the soil and groundwater and the remediation of contaminated sites that cause human and environmental risks. On behalf of the Department of Environment, Nature and Energy of the Flemish government together with the Public Waste Agency of Flanders(OVAM), ECOREM was assigned to carry out this study. The scope of this study therefore focuses on the aspect of soil management that can be divided into two main policies, beïng the policy for the prevention of soil contamination from new activities(1) and the policy for the management and remediation of historical soil contamination from local sources like industrial sites(2). To form a soil management policy, Croatia must start from the legal obligations enforced by the European Union. One of the European Directives regulating the monitoring and protection of soil and groundwater is the new Industrial Emission Directive ('IED' - 2010/78/EU) from the 24th of November 2010. Whereas the framework of the Directive is larger than contamination of soil , the focus of this study was limited to soil contamination only. In order to comply with the existing EU policy contributing to soil protection, the regulations in the IED, the Croatian government needs to adapt existing legislations or apply new regulations regarding soil monitoring for the industrial activities. Also other EU Directives enforce actions contributing to soil protection. Therefore, a questionnaire with different sorts of questions was sent to the different stakeholders (environmental institutes, agencies, ministries,…). The results were interpreted and allowed Ecorem, being the environmental consultant, to evaluate the gaps in the environmental and soil management policy. This study gives advice on how

  6. Secondary caries and microleakage.

    Science.gov (United States)

    Jokstad, Asbjørn

    2016-01-01

    To critically appraise experimental ex vivo research that has focused on secondary caries, and to offer possible explanations for the seemingly poor correlation to clinical observations. The literature relating to the etiopathogenesis or prevention of secondary caries gained from experimental ex vivo research was reviewed, with particular emphasis on microleakage and artificial caries-like lesions. It is doubtful whether a caries wall lesion can exist independently of an outer enamel caries lesion. Microleakage experiments apparently continue to emerge regardless of multiple reviews questioning the reliability and validity of the method. Several of the approaches used to generate artificial caries-like lesions are very aggressive. Remarkably little discussion has evolved about how these aggressive approaches create microenvironments that do not occur in reality. Corrosion- and biodegradation products may influence the biofilm qualitatively and quantitatively and it is difficult to replicate these variables in any ex vivo environment. Clinical data sampling method, patient demography as well as study methodology influences the incidence and prevalence estimates of secondary caries. Clinical results based on clinical work in settings where cost per unit time is of nominal concern do not provide any indications on how the restorative material will perform when placed by the average dentists in the mouths of their spectrum of patients during a busy workday. The term "wall lesion" including its variants is ill defined, has been, and is still being used indiscriminately. Stakeholders should avoid using this ambiguous label due to its connotation to an entity that does not exist per se. Copyright © 2015 Academy of Dental Materials. Published by Elsevier Ltd.

    2010-01-01

    The multifarious issues of health and safety at work require multi-disciplinary skills, both in the risk assessment and in the subsequent definition and management of preventive measures, and this requires a renewed operational protocol that supports integration and co-operation between the technical prevention figures. Thus, between occupational physicians and technical advisers there should be a concrete and fruitful interaction, which should not be episodic or occasional, but a modus operandi systematic and constant. In this contribution is discussed as the technical prevention figures should be included in the Health and Safety Management System and should make a specific contribution in defining corporate policies on prevention. In particular it is outlined the role that the occupational physician may play in the development of prevention and health promotion activities within the strategies of corporate social responsibility.

  9. From technical quality assurance of radiotherapy to a comprehensive quality of service management system

    International Nuclear Information System (INIS)

    Kehoe, T.; Rugg, L.

    1999-01-01

    A hierarchy of dosimetry, planning and machine performance checks and evaluations of clinical outcomes have been widely used in radiotherapy for decades. Procedures, codes of practice and guidance are readily available on the technical aspects of radiotherapy treatments, maintenance of which is achieved by quality control checks within a quality assurance approach to radiotherapy. Recently a series of high profile, well-publicised treatment accidents resulting in damage to patients have focused the attention of both professionals and the public. There is now pressure to introduce formal quality management systems. Patients and their relatives/carers are having their expectations raised but their definition of a quality service differs from that generally considered by the oncology professionals. Most departmental managers and staff have wide experience of quality control checks. They understand the philosophy of quality assurance. However the idea of formal quality systems/quality management is alien to them. What is a professional/departmental manager to do? This paper addresses that question by discussing the underlying principles of quality management covering service provision as well as technical radiotherapy treatment delivery and by providing some guidance based on experience in the practical implementation of quality management through three stages of development: a QA programme incorporating checks on essential parts of the technical treatment delivery, a formal documented certified QA system focusing on technical treatment delivery, a comprehensive quality management system covering all parts of a service. One possible action plan is provided indicating progress through the three stages of development based on experience in one large Radiation Oncology Department. With planning, resources and commitment. a comprehensive quality of service management system is achievable in radiotherapy. (author.)

    This study was conducted to suggest the development of a learning management system for dental radiology education using the Modular Object-Oriented Dynamic Learning Environment (Moodle). Moodle is a well-known and verified open-source software-learning management system (OSS-LMS). The Moodle software was installed on a server computer and customized for dental radiology education. The system was implemented for teaching undergraduate students to diagnose dental caries in panoramic images. Questions were chosen that could assess students' diagnosis ability. Students were given several questions corresponding to each of 100 panoramic images. The installation and customization of Moodle was feasible, cost-effective, and time-saving. By having students answer questions repeatedly, it was possible to train them to examine panoramic images sequentially and thoroughly. Based on its educational efficiency and efficacy, the adaptation of an OSS-LMS in dental school may be highly recommended. The system could be extended to continuing education for dentists. Further studies on the objective evaluation of knowledge acquisition and retention are needed.

    2017-12-01

    Full Text Available While Integrated Pest Management (IPM is a sustainable approach of pest control, contributing to reduced use of pesticides and risks on human health and the environment, farmers have shown limited interest in practicing this method. The present study explored the levels of technical knowledge about integrated management of the olive fly (Bactrocera oleae among olive growers in Roudbar County of Iran and factors underpinning olive farmers’ technical knowledge of integrated management. Data were collected in a survey of olive farmers, on the basis of a structured questionnaire. Almost half of the farmers (48.4% had good to excellent levels of technical knowledge of integrated management, while almost a third of the farmers (35.4% had a moderate knowledge level. However, a noticeable portion of the farmers (15.9% had poor knowledge of integrated management. Moreover, most farmers showed average knowledge of the adverse effects of pesticides on human health. While most farmers showed good levels of social participation, cooperation with institutes, and participation in extension activities, they showed low levels of community involvement (involvement in a group of people that have and share common interests with each other. Olive imports and the lack of a common action for olive fly control were perceived as the main barriers of IPM adoption among most farmers. Regression analysis revealed that increased community involvement, large area under olive farming, participation in education activities, and high farming experience promoted farmers’ technical knowledge of integrated olive fly control. Strengthening growers’ technical knowledge of IPM through community involvement and extension services among inexperienced small-scale olive farmers is recommended for reducing possible unnecessary insecticide sprays in olive production.

    Lasierra, Nelia; Alesanco, Alvaro; García, José

    2012-07-01

    This paper presents the design and implementation of an architecture based on the integration of simple network management protocol version 3 (SNMPv3) and the standard ISO/IEEE 11073 (X73) to manage technical information in home-based telemonitoring scenarios. This architecture includes the development of an SNMPv3-proxyX73 agent which comprises a management information base (MIB) module adapted to X73. In the proposed scenario, medical devices (MDs) send information to a concentrator device [designated as compute engine (CE)] using the X73 standard. This information together with extra information collected in the CE is stored in the developed MIB. Finally, the information collected is available for remote access via SNMP connection. Moreover, alarms and events can be configured by an external manager in order to provide warnings of irregularities in the MDs' technical performance evaluation. This proposed SNMPv3 agent provides a solution to integrate and unify technical device management in home-based telemonitoring scenarios fully adapted to X73.

    Full Text Available Caries remains the most prevalent non-contagious infectious disease in humans. It is clear that the current approaches to decrease the prevalence of caries in human populations, including water fluoridation and school-based programs, are not enough to protect everyone. The scientific community has suggested the need for innovative work in a number of areas in cariology, encompassing disease etiology, epidemiology, definition, prevention, and treatment. We have pioneered the work on genetic studies to identify genes and genetic markers of diagnostic, prognostic, and therapeutic value. This paper summarizes a presentation that elaborated on these initial findings.

    2013-02-01

    To critically appraise evidence for the prediction of caries using four caries risk assessment (CRA) systems/guidelines (Cariogram, Caries Management by Risk Assessment (CAMBRA), American Dental Association (ADA), and American Academy of Pediatric Dentistry (AAPD)). This review focused on prospective cohort studies or randomized controlled trials. A systematic search strategy was developed to locate papers published in Medline Ovid and Cochrane databases. The search identified 539 scientific reports, and after title and abstract review, 137 were selected for full review and 14 met the following inclusion criteria: (i) used as validating criterion caries incidence/increment, (ii) involved human subjects and natural carious lesions, and (iii) published in peer-reviewed journals. In addition, papers were excluded if they met one or more of the following criteria: (i) incomplete description of sample selection, outcomes, or small sample size and (ii) not meeting the criteria for best evidence under the prognosis category of the Oxford Centre for Evidence-Based Medicine. There are wide variations among the systems in terms of definitions of caries risk categories, type and number of risk factors/markers, and disease indicators. The Cariogram combined sensitivity and specificity for predicting caries in permanent dentition ranges from 110 to 139 and is the only system for which prospective studies have been conducted to assess its validity. The Cariogram had limited prediction utility in preschool children, and a moderate to good performance for sorting out elderly individuals into caries risk groups. One retrospective analysis on CAMBRA's CRA reported higher incidence of cavitated lesions among those assessed as extreme-risk patients when compared with those at low risk. The evidence on the validity for existing systems for CRA is limited. It is unknown if the identification of high-risk individuals can lead to more effective long-term patient management that prevents

    Caries management by risk assessment (CAMBRA) is an evidence-based model intended to provide dentists with a protocol for diagnosis, treatment, and prevention of caries by assessing and addressing a patient's overall oral health. The aim of this review was to examine the literature on CAMBRA to determine its efficacy. Clinical studies demonstrate that the CAMBRA approach is an effective concept that is both predictive of dental caries development and accurate in outlining appropriate treatment options and preventive strategies that can reduce the morbidity of this common disease process across all patient demographics.

    Full Text Available Students of technical universities often do not understand why their studies should include learning management skills (in addition to the study of economics. However, not only the experience of graduates but also the requirements of their future employers show that education in the field of the management should provide training, skills and practical testing. It is only a matter of time before graduates of technical university take up leading positions or become part of a team working on some complicated technical problem. A classical technical education is no longer sufficient and, aboveall, it is employees with knowledge of economics and with managerial skills, specifically soft skills that come to the fore. It is evident from ample experience that people’s individual dispositions play a role in learning soft skills, but many of these skills can also be acquired by progressive training. The question is which form of teaching to choose to enable necessary skills to be learned, without at the same discouraging students by offering them potentially unattractive courses. These are the issues that will be treated in this paper.

  6. Adaptive management: The U.S. Department of the Interior technical guide

    Williams, B K; Szaro, Robert C.; Shapiro, Carl D.

    2009-01-01

    The purpose of this technical guide is to present an operational definition of adaptive management, identify the conditions in which adaptive management should be considered, and describe the process of using adaptive management for managing natural resources. The guide is not an exhaustive discussion of adaptive management, nor does it include detailed specifications for individual projects. However, it should aid U.S. Department of the Interior (DOI) managers and practitioners in determining when and how to apply adaptive management. Adaptive management is framed within the context of structured decision making, with an emphasis on uncertainty about resource responses to management actions and the value of reducing that uncertainty to improve management. Though learning plays a key role in adaptive management, it is seen here as a means to an end, namely good management, and not an end in itself. The operational definition used in the guide is adopted from the National Research Council, which characterizes adaptive management as an iterative learning process producing improved understanding and improved management over time: Adaptive management [is a decision process that] promotes flexible decision making that can be adjusted in the face of uncertainties as outcomes from management actions and other events become better understood. Careful monitoring of these outcomes both advances scientific understanding and helps adjust policies or operations as part of an iterative learning process. Adaptive management also recognizes the importance of natural variability in contributing to ecological resilience and productivity. It is not a ‘trial and error’ process, but rather emphasizes learning while doing. Adaptive management does not represent an end in itself, but rather a means to more effective decisions and enhanced benefits. Its true measure is in how well it helps meet environmental, social, and economic goals, increases scientific knowledge, and reduces

    To identify barriers to participation in a primary oral health care programme aimed at preventing early childhood caries, as perceived by nurses. Of a total of 140 randomly selected nurses employed in 40 government health centres in Lima, 123 completed a pre-tested questionnaire. Background variables were districts' 'socio-economic status' (SES) and 'years of experience'. Factor analysis was performed. ANOVA was applied for testing the influence of the background variables on the barrier factors. Chi-square test was applied to test for differences between single item barriers and the background variables. The Likert-scale (1-4) was used. There was no statistical significant effect of 'SES' or of 'years of experience' of nurses on any of the 7 barrier factors, nor on the 11 single item barrier factors. The highest mean score (3.81) was obtained for the barrier factor 'importance of oral health', followed by 'perceived responsibility' (3.44). The lowest mean score was (1.70) for 'knowledge on caries prevention'. Nurses consider oral health very important and are willing to participate actively in programmes aimed at reducing Early Childhood Caries, provided that they will be trained well and that the director and dentists of the health centre give their consent.

    We sought to evaluate the validity of two non-technical skills evaluation instruments, the Anaesthetists' Non-Technical Skills (ANTS) behavioural marker system and the Ottawa Global Rating Scale (GRS), to apply them to anaesthesia training. The content validity, response process, internal structure, relations with other variables and consequences were described for validity evidence. Simulated crisis management sessions were initiated during which two trained raters evaluated the performance of postgraduate first-, second- and third-year (PGY-1, PGY-2 and PGY-3) anaesthesia residents. The study included 70 participants, composed of 24 PGY-1, 24 PGY-2 and 22 PGY-3 residents. Both instruments differentiated the non-technical skills of PGY-1 from PGY-3 residents ( P skills were 0.86, 0.83, 0.84, 0.87, 0.80 and 0.86, respectively. The Cronbach's alpha for internal consistency of the ANTS instrument was 0.93, and was 0.96 for the Ottawa GRS. There was a high correlation between the ANTS and Ottawa GRS. The raters reported the ease of use of the Ottawa GRS compared to the ANTS. We found sufficient evidence of validity in the ANTS instrument and the Ottawa GRS for the evaluation of non-technical skills in a simulated anaesthesia setting, but the Ottawa GRS was more practical and had higher reliability.

    'Technical Authority' is a term used to describe a corporate framework and process that effectively manages technical and safety issues and risks in a forward-looking manner, providing a lineage of accountability in making independent technical decisions. Specific duties are delegated to designated, qualified Technical Authority personnel who facilitate the process. Technical Authority promotes engineering excellence to support improved project performance during all life cycle phases of facilities. The Technical Authority process was successfully deployed at the U.S. Navy Naval Sea Systems (NAVSEA) Command in 1997, and is applied to all life cycle phases of Navy combatant ships in a climate of down-sizing technical resources under increasing operational requirements and budgetary pressures. The authors believe that the Department's Office of Environmental Management (EM) can benefit from establishing a Technical Authority framework to enhance its technical decision-making. This paper provides an overview of Technical Authority, a brief history, and plans for its near-term implementation in EM. (authors)

  10. Caries detection in dental radiographs

    Dunn, S.M.

    1987-01-01

    Caries, or the decay of teeth are difficult to automatically detect in dental radiographs because of the small area of the image that is occupied by the decay. Images of dental radiographs has distinct regions of homogeneous gray levels, and therefore naturally lead to a segmentation based automatic caries detection algorithm. This paper describes a method for caries detection based on a multiclass, area independent thresholding and segmenting scheme. This multiclass thresholding algorithm is an extension of the uniform error threshold, an area independent, distribution free thresholding method used for images of only two classes of objects. The authors first consider the problem of caries detection and the image features that characterize the presence of caries. Next, the uniform error threshold is reviewed, and the general multiclass uniform error threshold algorithm is presented. This algorithm is used to automatically detect caries in dental radiographs

    Full Text Available Depreciation policy and depreciation in particular play a number of functions at an enterprise. The modern stage of scientific studies describes the essence and breadth of the “depreciation” notion for an enterprise rather deeply. The article considers depreciation as a tool of managing technical resources at an enterprise. It conducts a critical review of modern approaches to determination of depreciation and identifies its functions. The author carries out a deep analysis of modern views on the existing concepts of depreciation essence and its place in managing enterprise assets. The article reveals the essence of the “depreciation policy” notion. It provides examples of influence of different types of the depreciation policy upon the state and rate of renovation of technical resources at an enterprise. In the result the author offers types of the depreciation policy of an enterprise depending on the desired rate of renovation of the technical base and desired volume of the capital released into circulation.

Professional clinical management of caries has been very successful in cases of different severities of disease manifestations. However, tertiary management of this disease has been gaining attention, with numerous methods and agents emerging on a daily basis. Higher intake of nutritive sweeteners can result in higher energy intake and lower diet quality and thereby predispose an individual to conditions like obesity, cardiovascular disorders, and type 2 diabetes mellitus. Non-nutritive sweeteners have gained popularity as they are sweeter and are required in substantially lesser quantities. Xylitol, a five-carbon sugar polyol, has been found to be promising in reducing dental caries disease and also reversing the process of early caries. This paper throws light on the role and effects of various forms of xylitol on dental caries and oral hygiene status of an individual. Keywords: xylitol, caries preventive effect, oral flora

    The United States and Russia are dismantling nuclear weapons and generating hundreds of tons of excess plutonium and high enriched uranium fissile nuclear materials that require disposition. The U.S. Department of Energy and Russian Minatom organizations.are planning and implementing safe, secure storage and disposition operations for these materials in numerous facilities. This provides a new opportunity for technical exchanges between Russian and Western scientists that can establish an improved and sustained common safety culture for handling these materials. An initiative that develops and uses personal relationships and joint projects among Russian and Western participants involved in fissile nuclear materials safety management contributes to improving nuclear materials nonproliferation and to making a safer world. Technical exchanges and workshops are being used to systematically identify opportunities in the nuclear fissile materials facilities to improve and ensure the safety of workers, the public, and the environment

    1996-01-01

    The remedial strategy for addressing contaminated environmental media was recently finalized for the US Department of Energy's (DOE) Fernald Environmental Management Project (FEMP) following almost 10 years of detailed technical analysis. The FEMP represents one of the first major nuclear facilities to successfully complete the Remedial Investigation/Feasibility Study (RI/FS) phase of the environmental restoration process. A critical element of this success was the establishment of sensible cleanup levels for contaminated soil and groundwater both on and off the FEMP property. These cleanup levels were derived based upon a strict application of Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) regulations and guidance, coupled with positive input from the regulatory agencies and the local community regarding projected future land uses for the site. The approach for establishing the cleanup levels was based upon a Feasibility Study (FS) strategy that examined a bounding range of viable future land uses for the site. Within each land use, the cost and technical implications of a range of health-protective cleanup levels for the environmental media were analyzed. Technical considerations in driving these cleanup levels included: direct exposure routes to viable human receptors; cross- media impacts to air, surface water, and groundwater; technical practicality of attaining the levels; volume of affected media; impact to sensitive environmental receptors or ecosystems; and cost. This paper will discuss the technical approach used to support the finalization of the cleanup levels for the site. The final cleanup levels provide the last remaining significant piece to the puzzle of establishing a final site-wide remedial strategy for the FEMP, and positions the facility for the expedient completion of site-wide remedial activities

No language or year restrictions were used. Randomised controlled trials assessing the effects of xylitol products on dental caries in children and adults. Two review authors independently screened the results of the electronic searches, extracted data and assessed the risk of bias of the included studies. Authors were contacted where possible for missing data or clarification where feasible. For continuous outcomes, means and standard deviations were used to obtain the mean difference and 95% confidence interval (CI). Continuous data was used to calculate prevented fractions (PF) and 95% CIs to summarise the percentage reduction in caries. For dichotomous outcomes, reported risk ratios (RR) and 95% CIs were used. As there were fewer than four studies included in the meta-analysis, a fixed effect model was used. Ten studies were included with a total of 5903 participants. One study was assessed as being at low risk of bias, two were assessed as unclear risk of bias with seven at high risk of bias. Over 2.5–3 years, low quality evidence demonstrated that with 4216 children analysed, a fluoride toothpaste with 10% xylitol (exact dosage unsure) reduced caries by 13% when compared to a fluoride only toothpaste. (PF −0.13, 95% CI −0.18 to −0.08. Remaining evidence of the use of xylitol in children has risk of bias and uncertainty of effect and was therefore insufficient to determine a benefit from xylitol. Four studies reported that there were no adverse effects from any of the interventions. Two studies reported similar rates of adverse effects between study arms. The remaining studies either mentioned adverse effects

    A Committee of Inquiry, consisting of members of the Canadian Dam Safety Association, was set up by the Government of Quebec following the Saguenay-Lac Saint Jean disaster in July 1996. The report of the Scientific and Technical Committee was published in two volumes. In this English language version Volume 1 contains the report of the Committee, including its conclusions and recommendations on how the management of dams might be improved in the future. Volume 2 contains a series of appendices, mostly of technical data, the report of the Advisory Board and a summary of public hearings held by the Committee. In the course of the Committee's investigation, the basins and physical characteristics of the watersheds that were most heavily impacted were subjected to intense examination. An examination of the existing framework and regulations for the management of the structures, and a thorough evaluation of the structures themselves, were also part of the inquiry. It was concluded that the flood was an exceptional phenomenon, one that the existing infrastructure and services were never built to resist. The inquiry also reviewed existing infrastructure codes adopted by the Ministry of Transportation, and probed the responsibilities of the government, the owners, and the regional and municipal authorities. Finally, the committee provided a series of recommendations for a much stricter framework for the design, surveillance and management of water retaining works, designed to prevent recurrence of the 1996 disaster. tabs., figs

    In the last 50 years, technological advances have accelerated at a rate unprecedented in history. We are experiencing a tremendous expansion of scientific and technological effort in many directions, and the result is a fantastic increase in the accumulation of scientific and technical information (STI) and knowledge. An integral part of the research and development (R&D) process is the STI associated with it. STI is both a raw material (input) and a product (output) of this process. The topics addressed include the following: the value of STI, management of an STI program, program policy and guidance, organizational structure, data sources, training/orientation, and the current information environment.

    Managing the ageing of fuel cycle facilities (FCFs) means, as for other nuclear installations, ensuring the availability of required safety functions throughout their service life while taking into account the changes that occur with time and use. This technical opinion paper identifies a set of good practices by benchmarking strategies and good practices on coping with physical ageing and obsolescence from the facility design stage until decommissioning. It should be of particular interest to nuclear safety regulators, fuel cycle facilities operators and fuel cycle researchers [fr

  10. Dental reductions and dental caries.

    Anderson, D L; Popovich, F

    1977-11-01

    Although first permanent molar hypoconulid absence, third molar agenesis, and small tooth size are all part of evolutionary trend of dental retardation, each bears a different relationship to dental caries. Caries prevalence in the maxillary and mandibular permanent first molars of the Burlington Research Centre serial experimental group at age 16 years was less in the children whose first molars were missing the hypoconulid. Conversely, caries prevalence in mandibular first molars was greater in the children who had agenesis of third molars. The extraction of first molars due to caries was more frequent in children with agenesis of third molars, less frequent in those with absence of hypoconulids of the first molars and unrelated to tooth size. Caries prevalence was less in small teeth, and occurred least in the small mandibular first molars with four cusps. Whereas this is in harmony with the hypothesis that evolutionary dental reductions resulted from the pressure of caries, the increased prevalence of caries and extractions coinciding with third molar agenesis does not support this view. In addition, agenesis of hypoconulids and agenesis of third molars were related to changes in structures unrelated to caries.

  11. Dental caries: an updated medical model of risk assessment.

    Kutsch, V Kim

    2014-04-01

    Dental caries is a transmissible, complex biofilm disease that creates prolonged periods of low pH in the mouth, resulting in a net mineral loss from the teeth. Historically, the disease model for dental caries consisted of mutans streptococci and Lactobacillus species, and the dental profession focused on restoring the lesions/damage from the disease by using a surgical model. The current recommendation is to implement a risk-assessment-based medical model called CAMBRA (caries management by risk assessment) to diagnose and treat dental caries. Unfortunately, many of the suggestions of CAMBRA have been overly complicated and confusing for clinicians. The risk of caries, however, is usually related to just a few common factors, and these factors result in common patterns of disease. This article examines the biofilm model of dental caries, identifies the common disease patterns, and discusses their targeted therapeutic strategies to make CAMBRA more easily adaptable for the privately practicing professional.

  12. A method for strategic technical life cycle management of real estates

    Energy Technology Data Exchange (ETDEWEB)

    Koskelo, T.

    2005-07-01

    This research study focuses on the strategic technical life cycle management (TLCM) of real estate. In the early phases of the study it became clear that very often the performance of TLCM was not perceived as satisfactory: there were problems in the purchasing and provision of technical services, TLCM was not performed according to real estate specific needs and objective-setting for building characteristics did not serve cost-effective ownership. The study focuses on four research questions. The first research question is: What is the status of TLCM processes in the real estate sector. The underlying theories, key concepts, methods and tools in the real estate sector as well as practices related to the domain of TLCM are studied, along with the performance of TLCM as perceived by stakeholders. The initial aim was to establish whether there is a solid foundation of appropriate theories, key concepts and methods for TLCM, and was approached through a literature review and interview studies. Another aim of this preliminary phase was to define the appropriate scientific approach for the study and refine the further research questions. At the beginning of the study, it was not clear if there even was a theoretical background and therefore both hermeneutic and constructive approaches were possible depending on the results obtained in elaborating the first research question. According to the preliminary studies, there was no solid foundation of appropriate theories and key concepts for TLCM. There was no satisfactory method for performing TLCM, and one needed to be developed. Therefore the second research question asked: by what means can we successfully develop and deploy such a method. This research was carried out using the constructive approach to develop and test a new method for TLCM. The third research question focused on the method itself: What are the characteristics and capabilities required of such a method. This was approached by interview studies and

  13. Determining the Technical Competencies of Construction Managers in the Malaysia’s Construction Industry

    Full Text Available It is a common conviction that project management, construction management, and site management are the tools for improving the performance of the construction project as a whole. Notwithstanding the similarities and differences between all of them, construction management which consists of off-site and on-site activities is deemed to have the major influence on the succession of a project. Consequently, a competent construction manager is required throughout the particular phase to shape the construction stability and geared up to complete the proposed development as according to several common objectives. Nonetheless, a competent construction manager will not just appear “out of the blue”, they need to be teach, train, and develop in order to equip them with comprehensive competency sets. For that reason, education, training, and continuing professional development (CPD are in place to provide the required knowledge, skills, and abilities. However, the debates on the inadequacy and problems on current construction management programs are continued to impede Malaysia’s construction environment. It has been observed that lack of term of reference on the technical competency for construction manager is became the major setback. Hence, this paper tries to unfold the circumstances by offering a preliminary countermeasure to alleviate the situation through analysis of literatures. It was found that, the associated central phenomenon is believed to be explored holistically with the inclusion of multi layered thematic analysis as a tool to assist the exploration processes. Then, the respective outcomes from the analysis are deemed to be ready for subsequent phases, for instance the validation phase.

  14. Knowledge Management in Scientific and Technical Support Organizations for Regulatory Bodies: SEC NRS Experience

    2016-01-01

    Full text: Nuclear industry, similar to other high-tech industries, is based on knowledge and to a great extent depends on personnel qualification, their skills and abilities. Knowledge management processes were recognized of the utmost importance for the IAEA. The IAEA GA adopted a number of resolutions on nuclear knowledge. In this context, knowledge management is considered as an integrated, systematic approach to the process of assessment, obtaining, development, distribution, use, transfer and maintenance of knowledge related to achievement of strategic targets of organization development. KM makes it possible to learn lessons from its own experience. The report presents a long-term experience of SEC NRS in knowledge management and capacity building, which is critically important for SEC NRS as scientific and technical support organization for Rostechnadzor. KM in SEC NRS is performed through the HRM, primarily through HRD, assessment, motivation of the labor activity, and regulation of social-psychological processes. The practice of implementation of NKM through the functions of human resources management is of particular interest for embarking countries. The best practices will be reflected in the IAEA Safety Report “Knowledge Management for Regulatory Bodies and TSO”, which is currently being developed by a team of the IAEA experts. (author

  15. CSNI technical opinion papers no.5. Managing and regulating organisational change in nuclear installations

    International Nuclear Information System (INIS)

    2004-01-01

    Nuclear licensees are increasingly required to adapt to a more challenging commercial environment as electricity markets are liberalized. One of the costs that is often perceived as being amenable to control is staffing, and hence there is significant exploration of new strategies for managing this cost - for example, by reducing staffing levels, changing organisational structures, adopting new shift strategies, introducing new technology or increasing the proportion of work carried out by external contractors. However, if changes to staffing levels or organisational structures and systems are inadequately conceived or executed they have the potential to affect the way in which safety is managed. In this context, the NEA Committee on the Safety of Nuclear Installations (CSNI) and its Special Expert Group on Human and Organisational Factors (SEGHOF) organised an international workshop to discuss the management and regulation of organisational change in 2001. This technical opinion paper distills the findings of that workshop and sets out the factors that regulatory bodies might reasonably expect to be addressed within licensees arrangements to manage organisational change. The paper should be of particular interest to both regulators and managers of nuclear utilities. (author)

    1985-01-01

    The Space Station Program is highly complex not only in its technological goals and requirements but also in its organizational structure. Eight Contractor teams supporting four NASA centers plus Headquarters must depend on effective exchange of information--the lifeblood of the program. The Technical and Management Information System (TMIS) is the means by which this exchange can take place. Value of the TMIS in increasing productivity comes primarily from its ability to make the right information available to whomever needs it when it is needed. Productivity of the aerospace professional and how it can be enhanced by the use of specifically recommended techniques and procedures for information management using the TMIS are discussed.

    Computer graphics systems that provide interactive display and manipulation of three-dimensional data are powerful tools for the analysis and communication of technical information required for characterization and design of a geologic repository for nuclear waste. Greater understanding of site performance and repository design information is possible when performance-assessment modeling results can be visually analyzed in relation to site geologic and hydrologic information and engineering data for surface and subsurface facilities. In turn, this enhanced visualization capability provides better communication between technical staff and program management with respect to analysis of available information and prioritization of program planning. A commercially-available computer system was used to demonstrate some of the current technology for three-dimensional visualization within the architecture of systems for nuclear waste management. This computer system was used to interactively visualize and analyze the information for two examples: (1) site-characterization and engineering data for a potential geologic repository at Yucca Mountain, Nevada; and (2) three-dimensional simulations of a hypothetical release and transport of contaminants from a source of radionuclides to the vadose zone. Users may assess the three-dimensional distribution of data and modeling results by interactive zooming, rotating, slicing, and peeling operations. For those parts of the database where information is sparse or not available, the software incorporates models for the interpolation and extrapolation of data over the three-dimensional space of interest. 12 refs., 4 figs.

    The chemical substances that are used in the hospitals, and their remainders, represent risks for the environment, the health and security of those who work in these establishments, and of the civil population. The deficiency of a norm that establishes the directives for the handling responsible for such products in the hospitals that our country has motivated the elaboration of a technical scheme that serves as it guides for the correct manipulation, storage and safe disposition of chemical substances in the twenty-nine hospitals of the Caja Costarricense del Seguro Social, establishing Procedures of Standard Operation for its management. To development of the guideline proposal it took a sample of hospitals that includes three levels of comple complexity: national, regional and peripheral. Applying a methodology of evaluation of risks two factors of risk of hospitable were determined, the zones and the population but affected by the existence of chemical substances, which allowed to identify some operative deficiencies in the product handling diverse. The qualitative analysis of the results lead to the elaboration of a technical scheme that includes an instrument for the identification of risks, guideline for the management responsible for hospitable chemical substances, a friendly tool computations like complementary source of intelligence and the proposal of a governing group in charge of the monitoring of the fulfillment of these lineament.

    Physicians have to demonstrate non-technical skills, such as communication and team leading skills, while coping with critical incidents. These skills are not taught during medical education. A crisis resource management (CRM) training was established for 4th to 6th year medical students using a full-scale simulator mannikin (Emergency Care Simulator, ECS, METI). The learning objectives of the course were defined according to the key points of Gaba's CRM concept. The training consisted of theoretical and practical parts (3 simulation scenarios with debriefing). Students' self-assessment before and after the training provided the data for evaluation of the training outcome. A total of 65 students took part in the training. The course was well received in terms of overall course quality, debriefings and didactic presentation, the mean overall mark being 1.4 (1: best, 6: worst). After the course students felt significantly more confident when facing incidents in clinical practice. The main learning objectives were achieved. The effectiveness of applying the widely used ECS full-scale simulator in interdisciplinary teaching has been demonstrated. The training exposes students to crisis resource management issues and motivates them to develop non-technical skills.

    Maragliano-Muniz, Pamela

    2013-10-01

    Following the introduction of CAMBRA (Caries Management by Risk Assessment) in 2007, a number of recommendations for office protocols were introduced, and many companies have formulated products and procedures for implementing CAMBRA. As a result, the implementation of a caries management program can be confounding and overwhelming to a dental practitioner. Understanding risk factors as they contribute to the caries process can help mitigate confusion and guide the practitioner when selecting materials for their practice. Ultimately, knowing how the risk factors play a role in the progression of dental caries will lead to appropriate risk management and product recommendations. The purpose of this article is to discuss the contribution of risk factors to the caries process and to introduce strategies that restorative dentists can utilize to minimize caries risk.

    Lactobacilli have been associated with dental caries for over a century. Here, we review the pertinent literature along with findings from our own study to formulate a working hypothesis about the natural history and role of lactobacilli. Unlike most indigenous microbes that stably colonize a host, lactobacilli appear to be planktonic, opportunistic settlers that can gather and multiply only in certain restrictive niches of the host, at least within the oral cavity. We postulate that the following essential requirements are necessary for sustained colonization of lactobacilli in humans: 1) a stagnant, retentive niche that is mostly anaerobic; 2) a low pH milieu; and 3) ready access to carbohydrates. Three sites on the human body meet these specifications: caries lesions, the stomach, and the vagina. Only a handful of Lactobacillus species is found in caries lesions, but they are largely absent in caries-free children. Lactobacilli present in caries lesions represent both a major contributor to caries progression and a major reservoir to the gastrointestinal (GI) tract. We extend the assertion from other investigators that lactobacilli found in the GI tract originate in the oral cavity by proposing that lactobacilli in the oral cavity arise from caries lesions. This, in turn, leads us to reflect on the health implications of the lactobacilli in the mouth and downstream GI and to ponder whether these or any of the Lactobacillus species are truly indigenous to the human GI tract or the oral cavity.

    A number of clinical and histological studies have investigated caries-related changes in the primary tooth pulp, but the effect of caries site, as a clinical variable, has not been previously considered. This study sought to compare inflammatory changes within the pulp of primary molars according to the location of the caries lesion (occlusal or proximal). Eighty-three primary molars were extracted under general anaesthesia for caries and/or orthodontic reasons, and were split immediately after removal and fixed in 10% formalin. Teeth were then decalcified, sectioned, and stained with haematoxylin and eosin for histological examination using light microscopy. Caries depth was measured using a graticle, and the site of the caries lesion noted as occlusal or proximal. Samples were further classified into one of five subgroups according to the observed degree of pulpal inflammation. Key findings were that where caries depth was less than 50% of the total dentine thickness, there were no significant differences in inflammatory status according to caries site. In contrast, marked inflammatory changes were significantly more likely throughout the coronal pulp of teeth with proximal caries compared to teeth with occlusal caries where caries depth was equal to, or greater than, 50% of the total dentine thickness (P = 0.017, Fisher's exact test). Primary teeth with proximal carious lesions extending more than 50% through the dentine thickness appear to have more extensive inflammatory pulpal changes than teeth with occlusal caries of a similar depth. This finding has clinical implications and may help inform treatment decisions in the management of primary teeth with deep carious lesions.

    In response to increasing use of the subsurface, there is a need to modernise policies on sustainable use of the subsurface. This holds in particular for the densely populated Netherlands. We aimed to analyse current practice of subsurface management and the associated pressure points and to establish a conceptual overview of the technical issues related to sustainable management of the subsurface. Case studies on the exploitation of subsurface resources (including spatial use of the subsurface) were analysed, examining social relevance, environmental impact, pressure points and management solutions. The case studies ranged from constructing underground garages to geothermal exploitation. The following issues were identified for the technological/scientific aspects: site investigation, suitability, risk assessment, monitoring and measures in the event of failure. Additionally, the following general issues were identified for the administrative aspects: spatial planning, option assessment, precaution, transparency, responsibility and liability. These issues were explored on their technological implications within the framework of sustainable management of the subsurface. This resulted into the following key aspects: (1) sustainability assessment, (2) dealing with uncertainty and (3) policy instruments and governance. For all three aspects, different options were identified which might have a legal, economic or ethical background. The technological implications of these backgrounds have been identified. A set of recommendations for sustainable management of the subsurface resources (incl. space) was established: (1) management should be driven by scarcity, (2) always implement closed loop monitoring when the subsurface activities are high-risk, (3) when dealing with unknown features and heterogeneity, apply the precautionary principle, (4) responsibility and liability for damage must be set out in legislation and (5) sustainability should be incorporated in all

    InSOTEC is a three-year collaborative social sciences research project funded under the European Atomic Energy Community's 7th Framework Programme FP7. The project aims to generate a better understanding of the complex interplay between the technical and the social in the context of geological disposal of radioactive waste. In doing so, InSOTEC has moved beyond the social and technical division that is frequently being found in this context by - investigating the consideration of social sciences and the recognition of socio-technical combinations in research programs on geological disposal, - analyzing the socio-technical entanglement in selected contexts like siting, reversibility and retrievability, demonstrating safety and technology transfer on the basis of case studies, and - exploring the integration of diverse stakeholders in technology oriented networks. The analyses reveal that activities in the context of geological disposal, whether related to research, planning, siting etc., rather support the divide of social and technical aspects than fostering the consideration of their entanglement. Reasons identified for this are manifold. The wish to reduce complexity by focusing stakeholder involvement on social questions and fixing the technical part ''when acceptance is reached'' is only one of them. However, the analyses also show that over the long timescales of repository planning and implementation, robust management strategies must provide the flexibility to adapt to both technical and social developments and demands. Understanding the socio-technical interplay and creating structures for its consideration provides the basis for dealing with this challenge. This presentation will focus on the main findings of the InSOTEC project with regard to the consideration of socio-technical combinations in practice. These insights are currently under development and will be finalized at the end of the project in June 2014. We will reflect on

The project aims to generate a better understanding of the complex interplay between the technical and the social in the context of geological disposal of radioactive waste. In doing so, InSOTEC has moved beyond the social and technical division that is frequently being found in this context by - investigating the consideration of social sciences and the recognition of socio-technical combinations in research programs on geological disposal, - analyzing the socio-technical entanglement in selected contexts like siting, reversibility and retrievability, demonstrating safety and technology transfer on the basis of case studies, and - exploring the integration of diverse stakeholders in technology oriented networks. The analyses reveal that activities in the context of geological disposal, whether related to research, planning, siting etc., rather support the divide of social and technical aspects than fostering the consideration of their entanglement. Reasons identified for this are manifold. The wish to reduce complexity by focusing stakeholder involvement on social questions and fixing the technical part ''when acceptance is reached'' is only one of them. However, the analyses also show that over the long timescales of repository planning and implementation, robust management strategies must provide the flexibility to adapt to both technical and social developments and demands. Understanding the socio-technical interplay and creating structures for its consideration provides the basis for dealing with this challenge. This presentation will focus on the main findings of the InSOTEC project with regard to the consideration of socio-technical combinations in practice. These insights are currently under development and will be finalized at the end of the project in June 2014. We will reflect on

    Many changes have taken place since the SCP safety strategy was formulated; it needs to be revised or replaced. Four concepts would aid in the shift from a rigid, ecelctic, schedule-driven, all-or-nothing program to an incremental, evolving, and experimental but integrated program. These are a simple safety case, reversability, demonstrability, and decoupling operations of a repository from operation of reactors. A simple safety case based on containment can be made for a repository at Yucca Mountain. This containment strategy is based on the dryness of openings at Yucca Mountain, Extended Dry heat management, and long-lived containers. Reversibility is technically believable at Yucca Mountain because of extended retrievability and drift emplacement, if an MRS were co-located with the repository. Because the rock is unsaturated, extended retrievability is technically feasible at Yucca Mountain. Demonstrability could be improved at Yucca Mountain by planning for incremental progression toward operation and closure of a repository, possibly including a shift to underground retrievable storage. Demonstrability can also be improved by using natural analogs. Repository operation can be decoupled from reactor operation by use of an unconstrained MRS facility or at-reactor dry storage and multipurpose storage canister/casks

    OBJECTIVE: To assess the ability of multivariate models and single factors to correctly identify future caries development in pre-school children and schoolchildren/adolescents. STUDY DESIGN: A systematic literature search for relevant papers was conducted with pre-determined inclusion criteria....... Abstracts and full-text articles were assessed independently by two reviewers. The quality of studies was graded according to the QUADAS tool. The quality of evidence of models and single predictors was assessed using the GRADE approach. RESULTS: Ninety original articles fulfilled the inclusion criteria....... Seven studies had high quality, 35 moderate and the rest poor quality. The accuracy of multivariate models was higher for pre-school children than for schoolchildren/adolescents. However, the models had seldom been validated in independent populations, making their accuracy uncertain. Of the single...

    This report provides an overview of progress during FY 1991 for the Technical Support Program that is part of the ANL Technology Support Activity for DOE, Environmental Restoration and Waste Management (EM). The purpose is to evaluate, before hot start-up of the Defenses Waste Processing Facility (DWPF) and the West Valley Demonstration Project (WVDP), factors that are likely to affect glass reaction in an unsaturated environment typical of what may be expected for the candidate Yucca Mountain repository site. Specific goals for the testing program include the following: (1) to review and evaluate available information on parameters that will be important in establishing the long-term performance of glass in a repository environment; (2) to perform testing to further quantify the effects of important variables where there are deficiencies in the available data; and (3) to initiate long-term testing that will bound glass performance under a range of conditions applicable to repository disposal

    Full Text Available The objective of this study was to evaluate the effect of pasture irrigation on the technical and management indicators of 20 demonstrative units participating in the “Balde Cheio” Program in the state of Rio de Janeiro from January to December 2011. The following variables were obtained: dam/labor ratio, herd size/labor ratio, milk yield/labor ratio, animals/production area, percentage of lactating cows, and milk yield. Return was analyzed considering gross margin, net margin, outcome (profit or loss, and profitability. The data were analyzed using the PASW 18.0 software. Pasture irrigation did not significantly alter the indicators studied. The greater profitability and return of farms using pasture irrigation were the consequence of better animal production rates/day and per ha/year. When gross margin, net margin and outcome using total revenue are considered, there is decapitalization of the farms. 

  3. A parameter network and model pyramid for managing technical information flow

    Prototypes of information management tools have been developed that can help communicate the technical basis for nuclear waste disposal to a broad audience of program scientists and engineers, project managers, and informed observers from stakeholder organizations. These tools include system engineering concepts, parameter networks expressed as influence diagrams, associated model hierarchies, and a relational database. These tools are used to express relationships among data-collection parameters, model input parameters, model output parameters, systems requirements, physical elements of a system description, and functional analysis of the contribution of physical elements and their associated parameters in satisfying the system requirements. By organizing parameters, models, physical elements, functions, and requirements in a visually reviewable network and a relational database the severe communication challenges facing participants in the nuclear waste dialog can be addressed. The network identifies the influences that data collected in the field have on measures of repository suitability, providing a visual, traceable map that clarifies the role of data and models in supporting conclusions about repository suitability. The map allows conclusions to be traced directly to the underlying parameters and models. Uncertainty in these underlying elements can be exposed to open review in the context of the effects uncertainty has on judgements about suitability. A parameter network provides a stage upon which an informed social dialog about the technical merits of a nuclear waste repository can be conducted. The basis for such dialog must be that stage, if decisions about repository suitability are to be based on a repository's ability to meet requirements embodied in laws and regulations governing disposal of nuclear wastes

  5. Risk management in the oil and gas industry : integration of human, organisational and technical factors

    The overall objective of this thesis is to provide knowledge and tools for the major hazard risk assessment for offshore installations (and onshore plants) based on an improved understanding of the influence of organisational, human and technical (OMT) factors. This extensive objective was further described by the following sub-goals: 1. Identify and describe human and organisational barriers in risk analysis, 2. Provide knowledge regarding human, organisational and technical factors that influence safety barriers, 3. Define indicators that are suitable for the measurement of barrier performance, 4. Develop models for barrier performance reflecting human, organisational and technical factors These four sub-goals formed the basis for the more specific objectives in the articles. The Deepwater Horizon accident and Macondo blowout were important inputs for several of the articles. One important acknowledgement is that risk management of major hazards differs from managing occupational safety. Another is that managing risks in the oil and gas (O&G) industry demands a high level due to the potential severe consequences. Quantitative risk analyses/assessments (QRAs) are used for risk control in the O&G industry. An important part of the QRA process is to identify and describe barriers in risk analysis. A study of offshore QRAs (Skogdalen and Vinnem, 2011b) showed that there were large differences between the analyses regarding incorporation of human and organisational factors (HOFs). The study divided the QRAs into a four-level classification system. Level 1 QRAs did not describe or comment on HOFs at all. By contrast, relevant research projects were conducted to fulfil the requirements of level 3 analyses. At this level, there was a systematic collection of data related to HOFs. The methods for analyzing the data were systematic and documented, and the QRAs were adjusted according to the status of the HOFs. A second study of QRAs (Skogdalen and Vinnem, 2011a) revealed

  7. Risk in technical and scientific studies: general introduction to uncertainty management and the concept of risk

    International Nuclear Information System (INIS)

    Apostolakis, G.E.

    2004-01-01

    George Apostolakis (MIT) presented an introduction to the concept of risk and uncertainty management and their use in technical and scientific studies. He noted that Quantitative Risk Assessment (QRA) provides support to the overall treatment of a system as an integrated socio-technical system. Specifically, QRA aims to answer the questions: - What can go wrong (e.g., accident sequences or scenarios)? - How likely are these sequences or scenarios? - What are the consequences of these sequences or scenarios? The Quantitative Risk Assessment deals with two major types of uncertainty. An assessment requires a 'model of the world', and this preferably would be a deterministic model based on underlying processes. In practice, there are uncertainties in this model of the world relating to variability or randomness that cannot be accounted for directly in a deterministic model and that may require a probabilistic or aleatory model. Both deterministic and aleatory models of the world have assumptions and parameters, and there are 'state-of-knowledge' or epistemic uncertainties associated with these. Sensitivity studies or eliciting expert opinion can be used to address the uncertainties in assumptions, and the level of confidence in parameter values can be characterised using probability distributions (pdfs). Overall, the distinction between aleatory and epistemic uncertainties is not always clear, and both can be treated mathematically in the same way. Lessons on safety assessments that can be learnt from experience at nuclear power plants are that beliefs about what is important can be wrong if a risk assessment is not performed. Also, precautionary approaches are not always conservative if failure modes are not identified. Nevertheless, it is important to recognize that uncertainties will remain despite a quantitative risk assessment: e.g., is the scenario list complete, are the models accepted as reasonable, and are parameter probability distributions representative of

    Data collected from an exploratory study concerned with the technical communications practices of aerospace engineers and scientists were analyzed to test the primary assumption that aerospace managers and nonmanagers have different technical communications practices. Five assumptions were established for the analysis. Aerospace managers and nonmanagers were found to have different technical communications practices for three of the five assumptions tested. Although aerospace managers and nonmanagers were found to have different technical communications practices, the evidence was neither conclusive nor compelling that the presumption of difference in practices could be attributed to the duties performed by aerospace managers and nonmanagers.

    Contemporary tendencies in dentistry are based on the concept of maximal protection of healthy tooth tissues. Caries removal has been done traditionally with mechanical rotary instruments that are fast and precise. However, conventional cavity preparation has potential adverse effects to the pulp due to heat, pressure and vibrations. Moreover, drilling often causes pain and requires local anaesthesia, and these procedures are frequently perceived as unpleasant. Etiology, development and prevention of dental caries are better understood today and new restorative materials that bond micromechanically and/or chemically to dental tissues have been introduced. Thus, development of a new, less destructive caries removal technique is allowed. In the last decades, many alternative methods have been introduced in an attempt to replace rotary instruments. These are claimed to be efficient and selective for diseased tissues and to offer comfortable treatment to the patients. New methods include air abrasion, air polishing, ultrasonic, polymer burs, enzymes, systems for chemo-mechanical caries removal, and lasers. The aim of this paper was to discuss various caries removal techniques and possibilities of their use in clinical practice. Based on the literature review it can be concluded that none of the new caries removal methods can completely replace conventional rotary instruments.

    This paper describes the experience of TRANSPETRO's Oil Pipelines and Terminals Unit regarding an institutionalized knowledge management (KM) process of systematically promoting technical forums focused on: pipeline and terminal operations; industrial maintenance; and right-of-way activities management. This empirical work adds evidence that in the model of cooperative and communicative knowledge management it is necessary to motivate staff to provide the company with their tacit knowledge and to take a proactive part in knowledge management processes, particularly in technical forums. Within this KM perspective, technical forums have been held by TRANSPETRO for the following purposes: to discuss the main barriers and challenges the oil pipelines and terminals unit has to face in the coming years; to share and disseminate good practices concerning oil pipeline and terminal activities; to discuss new processes, methods and equipment developments with potential application in business and operational processes; to establish action plans concerning the main challenges, barriers and opportunities; to disseminate Research and Development (R and D) projects in course, new procedures, methods and equipment and to promote integration among forum attendees. The two year-experience in TRANSPETRO's Oil Pipelines and Terminals Unit revealed that technical forums have been an important instrument for cooperative and communicative knowledge management, according to evaluations from 173 attendees.

    Groundwater management has traditionally been observed as a study for long term policy measures to ensure that the water resource is sustainable. IBM Research, in association with the World Bank, extended this traditional analysis to include realtime groundwater management by building a context-aware, water rights management and permitting system. As part of this effort, one of the primary objectives was to develop a groundwater flow model that can help the policy makers with a visual overview of the current groundwater distribution. In addition, the system helps the policy makers simulate a range of scenarios and check the sustainability of the groundwater resource in a given region. The system also enables a license provider to check the effect of the introduction of a new well on the existing wells in the domain as well as the groundwater resource in general. This process simplifies how an engineer will determine if a new well should be approved. Distance to the nearest well neighbors and the maximum decreases in water levels of nearby wells are continually assessed and presented as evidence for an engineer to make the final judgment on approving the permit. The system also facilitates updated insights on the amount of groundwater left in an area and provides advice on how water fees should be structured to balance conservation and economic development goals. In this talk, we will discuss the concept of Digital Aquifer, the challenges in integrating modeling, technical and software aspects to develop a management system that helps policy makers and license providers with a robust decision making tool. We will concentrate on the groundwater model developed using the analytic element method that plays a very important role in the decision making aspects. Finally, the efficiency of this system and methodology is shown through a case study in Laguna Province, Philippines, which was done in collaboration with the National Water Resource Board, Philippines and World

    The Italian Air Quality legislation underwent sweeping changes with the implementation of the 1996 European Air Quality Framework Directive when the Italian administrative Regions were entrusted with air quality management tasks. The most recent Regional Air Quality Management Plans (AQMPs) highlighted the importance of Non-Technical Measures (NTMs), in addition to Technical Measures (TMs), in meeting environmental targets. The aim of the present work is to compile a list of all the TMs and NTMs taken into account in the Italian Regional AQMPs and to give in the target year, 2010, an estimation of SO 2, NO x and PM 10 emission reductions, of PM 10 concentration and of the health impact of PM 2.5 concentrations in terms of Life Expectancy Reduction. In order to do that, RAINS-Italy, as part of the National Integrated Modeling system for International Negotiation on atmospheric pollution (MINNI), has been applied. The management of TMs and NTMs inside RAINS have often obliged both the introduction of exogenous driving force scenarios and the control strategy modification. This has inspired a revision of the many NTM definitions and a clear choice of the definition adopted. It was finally highlighted that only few TMs and NTMs implemented in the AQMPs represent effective measures in reaching the environmental targets.

  13. Technical and management challenges associated with structural materials degradation in nuclear reactors in the future

    International Nuclear Information System (INIS)

    Ford, F.P.

    2007-01-01

    There are active plans worldwide to increase nuclear power production by significant amounts. In the near term (i.e. by 2020) this will be accomplished by, (a) increasing the power output of the existing reactors and extending their life, and by, (b) constructing new reactors that are very similar to the current water-cooled designs. Beyond 2025-2030, it is possible that new reactors (i.e. the 'GEN IV' designs) will be very different from those currently in service. A full discussion of the technical and management concerns associated with materials degradation that might arise over the next 40 years would need to address a wide range of topics. Quite apart from discussing the structural integrity issues for the materials of construction and the fuel cladding, the debate would also need to cover, for example, fuel resources and the associated issues of fuel cycle management and waste disposal, manufacturing capacity, inspection capabilities, human reliability, etc., since these all impact to one degree or another on the choice of material and the reactor operating conditions. For brevity, the scope of this article is confined to the integrity of the materials of construction for passive components in the current water-cooled reactors and the evolutionary designs (which will dominate the near term new constructions), and the very different GEN IV reactor designs. In all cases the operating environments will be more aggressive than currently encountered. For instance, the concerns for flow accelerated corrosion and flow-induced vibration will be increased under extended power uprate conditions for the current water-cooled reactors. Of greater concern, the design life will be at least 60 years for all of the new reactors and for those current reactors operating with extended licenses. This automatically presents challenges with regard to managing both irradiation damage in metallic and non-metallic materials of construction, and environmentally assisted cracking. This

  17. The implications of the new paradigm of dental caries.

    Science.gov (United States)

    Kidd, Edwina

    2011-12-01

    The caries process is the ubiquitous, natural metabolism in the biofilm that causes numerous fluctuations in pH. The interaction of this biofilm with the dental tissues may result in a caries lesion. However, lesion formation and progression can be controlled, particularly by disturbing plaque regularly with a fluoride containing toothpaste. This paradigm implies that everyone with teeth is at risk to lesion development. Treatment of caries is principally non-operative, involving plaque control, fluoride and a sensible diet. Operative dentistry repairs un-cleansable cavities and is part of plaque control. A diagnosis is a mental resting place on the way to a treatment decision. The relevant diagnostic features with respect to caries are lesion activity (active lesions require active management) and un-cleansable cavities. When teaching undergraduates, it is important that they are credited for the non-operative treatment of caries as well as for operative dentistry. This is equally important in dental practice where an appropriate skills mix of the dental team is required to deliver dental health cost-effectively. Training more dentists may be an expensive mistake as far as disease control is concerned. It is ironic that dentists make most money from operative care and specialist treatment when disease control could be delivered relatively cheaply. The key to dental health is regular and effective plaque control with a fluoride containing toothpaste, from cradle to grave. Copyright © 2011 Elsevier Ltd. All rights reserved.

  18. Technical Note: Seasonality in alpine water resources management - a regional assessment

    Science.gov (United States)

    Vanham, D.; Fleischhacker, E.; Rauch, W.

    2008-01-01

    Alpine regions are particularly affected by seasonal variations in water demand and water availability. Especially the winter period is critical from an operational point of view, as being characterised by high water demands due to tourism and low water availability due to the temporal storage of precipitation as snow and ice. The clear definition of summer and winter periods is thus an essential prerequisite for water resource management in alpine regions. This paper presents a GIS-based multi criteria method to determine the winter season. A snow cover duration dataset serves as basis for this analysis. Different water demand stakeholders, the alpine hydrology and the present day water supply infrastructure are taken into account. Technical snow-making and (winter) tourism were identified as the two major seasonal water demand stakeholders in the study area, which is the Kitzbueheler region in the Austrian Alps. Based upon different geographical datasets winter was defined as the period from December to March, and summer as the period from April to November. By determining potential regional water balance deficits or surpluses in the present day situation and in future, important management decisions such as water storage and allocation can be made and transposed to the local level.

  19. Generation management using batteries in wind farms: Economical and technical analysis for Spain

    International Nuclear Information System (INIS)

    Dufo-Lopez, Rodolfo; Bernal-Agustin, Jose L.; Dominguez-Navarro, Jose A.

    2009-01-01

    This paper presents an hourly management method for energy generated in grid-connected wind farms using battery storage (Wind-Batteries systems). The method proposed is analysed technically and economically. Electricity generation in wind farms does not usually coincide with the electrical demand curve. If the wind-power penetration becomes high in the Spanish electrical grid, energy management will become necessary for some wind farms. A method is proposed in this paper to adjust the generation curve to the demand curve by storing electrical energy in batteries during off-peak hours (low demand) and selling stored energy to the grid during peak hours (high demand). With the results obtained and reported in this paper, for a Wind-Batteries system to be economically as profitable as a Wind-Only system, the selling price of the energy provided by the batteries during peak hours should be between 22 and 66 c Euro /kWh, depending on the technology and cost of the batteries. Comparison with flexible thermal generation has been performed. Additionally, the results are compared with those obtained if using hydrogen (Wind-Hydrogen system, which uses an electrolyser, hydrogen tank, and fuel cell instead of batteries), concluding that the Wind-Batteries system is both economically and energetically far more suitable

  20. Value of information in natural resource management: technical developments and application to pink-footed geese

    Science.gov (United States)

    Williams, Byron K.; Johnson, Fred A.

    2015-01-01

    The “value of information” (VOI) is a generic term for the increase in value resulting from better information to guide management, or alternatively, the value foregone under uncertainty about the impacts of management (Yokota and Thompson, Medical Decision Making 2004;24: 287). The value of information can be characterized in terms of several metrics, including the expected value of perfect information and the expected value of partial information. We extend the technical framework for the value of information by further developing the relationship between value metrics for partial and perfect information and describing patterns of their performance. We use two different expressions for the expected value of partial information to highlight its relationship to the expected value of perfect information. We also develop the expected value of partial information for hierarchical uncertainties. We highlight patterns in the value of information for the Svalbard population of the pink-footed goose (Anser brachyrhynchus), a population that is subject to uncertainty in both reproduction and survival functions. The framework for valuing information is seen as having widespread potential in resource decision making, and serves as a motivation for resource monitoring, assessment, and collaboration.

    2017-03-28

    The purpose of the SDAV institute is to provide tools and expertise in scientific data management, analysis, and visualization to DOE’s application scientists. Our goal is to actively work with application teams to assist them in achieving breakthrough science, and to provide technical solutions in the data management, analysis, and visualization regimes that are broadly used by the computational science community. Over the last 5 years members of our institute worked directly with application scientists and DOE leadership-class facilities to assist them by applying the best tools and technologies at our disposal. We also enhanced our tools based on input from scientists on their needs. Many of the applications we have been working with are based on connections with scientists established in previous years. However, we contacted additional scientists though our outreach activities, as well as engaging application teams running on leading DOE computing systems. Our approach is to employ an evolutionary development and deployment process: first considering the application of existing tools, followed by the customization necessary for each particular application, and then the deployment in real frameworks and infrastructures. The institute is organized into three areas, each with area leaders, who keep track of progress, engagement of application scientists, and results. The areas are: (1) Data Management, (2) Data Analysis, and (3) Visualization. Kitware has been involved in the Visualization area. This report covers Kitware’s contributions over the last 5 years (February 2012 – February 2017).

  5. Health promotion and dental caries

    Full Text Available The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies and actions such as food and health policies, and general hygiene (including oral hygiene, among others. For decades, a linear relationship between sugar consumption and caries has been observed. Recent data has indicated that this relationship is not as strong as it used to be before the widespread use of fluoride. However, diet is still a key factor acting in the carious process. Oral hygiene is a major aspect when it comes to caries, since dental biofilm is its etiological factor. Oral hygiene procedures are effective in controlling dental caries, especially if plaque removal is performed adequately and associated with fluoride. An alternative to a more efficient biofilm control in occlusal areas is the use of dental sealants, which are only indicated for caries-active individuals. If a cavity is formed as a consequence of the metabolic activity of the biofilm, a restorative material or a sealant can be placed to block access of the biofilm to the oral environment in order to prevent caries progress. The prevention of dental caries based on common risk-factor strategies (diet and hygiene should be supplemented by more disease-specific policies such as rational use of fluoride, and evidence-based dental health care.

    1985-01-01

    This review was performed for the US Department of Energy by a panel of the Board on Radioactive Waste Management under the National Research Council's Commission on Physical Sciences, Mathematics, and Resources. In summary, ORNL's waste management practices have kept offsite doses low; some of the practices are temporary and improvised - they may not be as satisfactory in the future; reducing anticipated future releases will be difficult because the limited number of candidate waste disposal locations are characterized by topographic peculiarities; and a major ORNL accomplishment has been the demonstration that hydrofracture can be a successful method of disposal for at least low- and intermediate-level waste. The panel obtained its information over a 2-year period by examining a large body of technical literature, by making six visits to the Oak Ridge National Laboratory, and through briefings by representatives of government agencies and their subcontractors. Chapter 2 contains the charge to the panel. Chapters 3, 4, and 5 describe the site, the waste that is present, and the methods used to handle it. Chapters 6 through 10 treat the manner in which the performance of the waste-handling system is monitored, the criteria against which performance is assessed, the panel's assessment of performance, and consideration of alternative methods for future handling of radioactive waste. Chapter 11 contains a brief comparison of ORNL with other sites. The panel's principal conclusions and recommendations are summarized below and treated in detail in subsequent chapters. In general, the conclusions and recommendations considered by the panel to be the most important are provided first. 123 refs., 30 figs., 24 tabs

    Research into complexities of software systems Fault Management (FM) and how architectural design decisions affect safety, preservation of assets, and maintenance of desired system functionality has coalesced into a technical reference (TR) suite that advances the provision of safety and mission assurance. The NASA Independent Verification and Validation (IV&V) Program, with Software Assurance Research Program support, extracted FM architectures across the IV&V portfolio to evaluate robustness, assess visibility for validation and test, and define software assurance methods applied to the architectures and designs. This investigation spanned IV&V projects with seven different primary developers, a wide range of sizes and complexities, and encompassed Deep Space Robotic, Human Spaceflight, and Earth Orbiter mission FM architectures. The initiative continues with an expansion of the TR suite to include Launch Vehicles, adding the benefit of investigating differences intrinsic to model-based FM architectures and insight into complexities of FM within an Agile software development environment, in order to improve awareness of how nontraditional processes affect FM architectural design and system health management. The identification of particular FM architectures, visibility, and associated IV&V techniques provides a TR suite that enables greater assurance that critical software systems will adequately protect against faults and respond to adverse conditions. Additionally, the role FM has with regard to strengthened security requirements, with potential to advance overall asset protection of flight software systems, is being addressed with the development of an adverse conditions database encompassing flight software vulnerabilities. Capitalizing on the established framework, this TR suite provides assurance capability for a variety of FM architectures and varied development approaches. Research results are being disseminated across NASA, other agencies, and the

    The reserves of uraniferous coal resource account for a certain proportion of all uranium resources in China. China began to mine the uraniferous coal deposits in late 1960s. In the process of mining, much research was conducted on the control and reduction of the radiation hazards in underground uraniferous coal mine. However, such mining practice was stopped for many reasons in late 1980s. During recent years, electricity shortages have taken place from time to time. In order to alleviate the shortages, the Chinese government has decided to further develop nuclear electricity. Under such circumstances, underground mining of uraniferous coal deposits will be restarted. In order to make sure that the radiation protection will be stressed and the radiation hazards will be controlled effectively in the underground uraniferous mine, this paper gives the basic knowledge of radiation protection, describes the radiation hazards to the miners and our national dosage standards implemented in the underground mine, and, on the basis of summing-up of the past experience in mine radiation protection, presents the technical and management measures for controlling and reducing radiation hazards.

    2018-03-05

    Classifications employed to measure dental caries should first of all reflect the dynamics of the disease, in order to provide a solid basis for subsequent treatment decisions and for further monitoring of dental health of individual patients and populations. The contemporary philosophy of dental caries management implies that nonoperative treatment of caries lesions should be implemented whenever possible, limiting operative interventions to the severe and irreversible cases. The ORCA Saturday Afternoon Symposium 2016, held back-to-back to the 63rd ORCA Congress in Athens, Greece, was intended to provide an update on general requirements for clinical caries diagnosis and to overview caries diagnostic classifications including their rationale, validation, advantages, and limitations. Clinical caries diagnostic criteria and caries management outcomes are interrelated, and any diagnostic classification disregarding this concept is outdated, according to the current understanding of oral health care. Choosing clinical caries diagnostic classifications that assess the activity status of detected lesions should be a priority for dental professionals since these classifications favor the best clinical practice directed towards nonoperative interventions. The choice of clinical caries diagnostic classifications in research, in clinical practice, and in public health services should be guided by the best available scientific evidence. The clinical caries diagnostic classifications should be universally applicable in all these fields. Policy making in oral health care and the underlying policy analyses should follow the same standards. Any clinical caries diagnostic classification disregarding the universality of its use is of limited or no interest in the context of the clinical caries diagnosis of today. © 2018 S.

    As a highly prevalent multifactorial disease, dental caries afflicts a large proportion of the world's population. As teeth are constantly bathed in saliva, the constituents and properties of this oral fluid play an essential role in the occurrence and progression of dental caries. Various inorganic (water and electrolytes) and organic (proteins and peptides) components may protect teeth from dental caries. This occurs via several functions, such as clearance of food debris and sugar, aggregation and elimination of microorganisms, buffering actions to neutralize acid, maintaining supersaturation with respect to tooth mineral, participation in formation of the acquired pellicle and antimicrobial defense. Modest evidence is available on the associations between dental caries and several salivary parameters, including flow rate, buffering capacity and abundance of mutans streptococci. Despite some controversial findings, the main body of the literature supports an elevated caries prevalence and/or incidence among people with a pathologically low saliva flow rate, compromised buffering capacity and early colonization or high titer of mutans streptococci in saliva. The evidence remains weak and/or inconsistent on the association between dental caries and other saliva parameters, such as other possible cariogenic species (Lactobacillus spp., Streptococcus sanguis group, Streptococcus salivarius, Actinomyces spp. and Candida albicans), diversity of saliva microbiomes, inorganic and organic constituents (electrolytes, immunoglobulins, other proteins and peptides) and some functional properties (sugar clearance rate, etc.). The complex interactions between salivary components and functions suggest that saliva has to be considered in its entirety to account for its total effects on teeth. © 2015 John Wiley & Sons A/S.

    The INL has carried out a demonstration of the RISMC approach for the purpose of configuration risk management. We have shown how improved accuracy and realism can be achieved by simulating changes in risk – as a function of different configurations – in order to determine safety margins as the plant is modified. We described the various technical issues that play a role in these configuration-based calculations with the intent that future applications can take advantage of the analysis benefits while avoiding some of the technical pitfalls that are found for these types of calculations. Specific recommendations have been provided on a variety of topics aimed at improving the safety margin analysis and strengthening the technical basis behind the analysis process.

    As a result of various economic, social and environmental factors, we can all experience the increase in importance of water resources at a global scale. As a consequence, we can also notice the increasing need of methods and systems capable of efficiently managing and combining the rich and heterogeneous data available that concerns, directly or indirectly, these water resources, such as in-situ monitoring station data, Earth Observation images and measurements, Meteorological modeling forecasts and Hydrological modeling. Under the scope of the MyWater project, we developed a water management system capable of satisfying just such needs, under a flexible platform capable of accommodating future challenges, not only in terms of sources of data but also on applicable models to extract information from it. From a methodological point of view, the MyWater platform obtains data from distinct sources, and in distinct formats, be they Satellite images or meteorological model forecasts, transforms and combines them in ways that allow them to be fed to a variety of hydrological models (such as MOHID Land, SIMGRO, etc…), which themselves can also be combined, using such approaches as those advocated by the OpenMI standard, to extract information in an automated and time efficient manner. Such an approach brings its own deal of challenges, and further research was developed under this project on the best ways to combine such data and on novel approaches to hydrological modeling (like the PriceXD model). From a technical point of view, the MyWater platform is structured according to a classical SOA architecture, with a flexible object oriented modular backend service responsible for all the model process management and data treatment, while the information extracted can be interacted with using a variety of frontends, from a web portal, including also a desktop client, down to mobile phone and tablet applications. From an operational point of view, a user can not only see

    1993-03-01

    Since the last reporting period by the Technical Advisory Committee (TAC) the emphasis of the work in the Canadian Nuclear Fuel Waste Management Program (CNFWMP) has been on the writing of the Environmental Impact Statement (EIS) and the associated set of nine primary reference documents as well as supporting documents. These are in preparation for submission to the Environmental Assessment Review Panel who will lead the national evaluation of the disposal concept under the auspices of the Federal Environmental Assessment Review Office (FEARO). The disposal concept developed over the last fourteen years by Atomic Energy of Canada Limited (AECL) and anticipated to be presented by means of the EIS in 1994, is based on a multiple system of natural and man-made barriers wherein nuclear waste is first enclosed in corrosion-resistant containers, designed to last at least 500 years, and then placed in a vault excavated 500 - 1000 m deep in granitic rocks of the Canadian Shield. After container emplacement either in or on the floor of the vault, and with a surrounding buffer material of a bentonite clay/sand mixture, the vault will be backfilled and sealed with crushed rock, buffer and sand, as will be the shafts and exploratory boreholes. The case study being presented by AECL to demonstrate the safety of this concept and the technology to implement it, relies on computer simulations of a hypothetical disposal site with geological characteristics similar to those at the Underground Research Laboratory (URL) in the Whiteshell Research Area (WRA) located in Manitoba. The preliminary simulation results suggest that safe containment can be achieved provided that the waste is surrounded by a sparsely-fractured zone of rock wherein movement of contaminants carried by groundwater is modelled as a diffusive as opposed to a advective process. The principal focus of work during the past year within the environmental and safety assessment has been to complete the Post

    The UK Defence Science and Technology Laboratory (Dstl) RPA Body was established to provide radiation protection advice to the UK Ministry of Defence and other UK Government organisations. It consists of around 20 individually certificated Qualified Experts (known as Radiation Protection Advisers (RPA) in the terminology of UK legislation) 15 health physicists (HP), and other support staff. The RPA Body operates to procedures that satisfy the requirements of the UK Heath and Safety Executive (HSE) (the primary regulator in the UK for radiation protection legislation) and as such is recognised by the HSE as an RPA Body. Individual RPAs, HPs and support staff are only appointed to the RPA Body when they are deemed suitable and can satisfy the various general and specific operational roles within the Body. The criteria and procedures for establishing suitability of a candidate to a role are described. In addition to the basic underpinning knowledge for RPAs (the equivalent of the 'qualified expert' defined in Article 1 of the Basic Safety Standards Directive 96/29/EURATOM, candidates for appointment to the RPA Body are required to demonstrate competence and suitability in specialist areas as determined by the business needs of Dstl RPA Body. The criteria and assessment processes are described. The technical management of the RPA Body is illustrated, stressing the importance of the selection and allocation of suitable individuals to specific tasks, using a competency matrix. Experience to date with the RPA Body processes has been very positive; the arrangements are sufficiently flexible such as to accommodate the changing legislative requirements and the business needs of the RPA Body. There are many additional benefits arising to Dstl and its customers as a result of operation as an RPA Body. (author)

    A program was established for DOE Environmental Restoration and Waste Management (EM) to evaluate factors that are anticipated to affect waste glass reaction during repository disposal, especially in an unsaturated environment typical of what may be expected for the proposed Yucca Mountain repository site. This report covers progress in FY 1992 on the following tasks: 1. A compendium of the characteristics of high-level nuclear waste borosilicate glass has been written. 2. A critical review of important parameters that affect the reactivity of glass in an unsaturated environment is being prepared. 3. A series of tests has been started to evaluate the reactivity of fully radioactive glasses in a high-level waste repository environment and compare it to the reactivity of synthetic, nonradioactive glasses of similar composition. 4. The effect of radiation upon the durability of waste glasses at a high glass surface area-to-liquid volume (SA/V) ratio and a high gas-to-liquid volume ratio will be assessed. These tests address both vapor and high SA/V liquid conditions. 5. A series of tests is being performed to compare the extent of reaction of nuclear waste glasses at various SAN ratios. Such differences in the SAN ratio may significantly affect glass durability. 6. A series of natural analogue tests is being analyzed to demonstrate a meaningful relationship between experimental and natural alteration conditions. 7. Analytical electron microscopy (AEM), infrared spectroscopys and nuclear resonant profiling are being used to assess the glass/water reaction pathway by identifying intermediate phases that appear on the reacting glass. Additionally, colloids from the leach solutions are being studied using AEM. 8. A technical review of AEM results is being provided. 9. A study of water diffusion involving nuclear waste glasses is being performed. 10. A mechanistically based model is being developed to predict the performance of glass over repository-relevant time periods

    The U.S. Department of Energy Office of Legacy Management (DOE-LM) manages the legacy contamination at the Riverton, WY, Processing Site – a former uranium milling site that operated from 1958 to 1963. The tailings and associated materials were removed in 1988-1989 and contaminants are currently flushing from the groundwater. DOE-LM commissioned an independent technical team to assess the status of the contaminant flushing, identify any issues or opportunities for DOE-LM, and provide key recommendations. The team applied a range of technical frameworks – spatial, temporal, hydrological and geochemical – in performing the evaluation. In each topic area, an in depth evaluation was performed using DOE-LM site data (e.g., chemical measurements in groundwater, surface water and soil, water levels, and historical records) along with information collected during the December 2013 site visit (e.g., plant type survey, geomorphology, and minerals that were observed, collected and evaluated).

  10. Risk perception of various technical options in the field of radioactive waste management

    International Nuclear Information System (INIS)

    Cameron, F.X.

    1996-01-01

    The author's group had a wide ranging discussion of risk and, at the very end of the discussion got to the question that was posed to them, which is that of risk perception of various technical options in the field of radioactive waste management. Some of the points that were made in this discussion is a reality that the group, as decision-makers, have to deal with, and it has to be treated as a reality. Secondly, the scientist looks at risk from the classic definition of ''probability times consequences'', but the public only looks at the consequences side of the equation, and too often the probability of something happening is treated as a probability of one that it will actually happen. A third problem that was identified in this area is that often the efforts to make the disposal of waste safer may contribute, in the public mind, to the fact that the risk is even more hazardous. And the last problem is that people do not trust what a decision maker is saying when he talks about the fact that there is little probability of something happening. The group then went on to a discussion of how he should try to treat risk perception. One point that was made is that voluntary acceptance of a risk is important. A second point that was made on how to deal with risk perception problems is that the group could try to put the risk of radioactive waste disposal in the perspective of other risks to society, from the chemical industry for instance. The group also talked about the possibility of putting the benefits in perspective for people. Another point was that the group should have different communications strategies for different audiences. But, the more the public is involved in the decision making process, the more comfortable they are going to be with the risk, and the more consistent the perception of risk may be with the scientific definition thereof. In terms of new technologies, new innovations on the generation and management of waste, although these may actually

    The goal of this quality assurance study was to explore the decision making of clinical faculty members at the University of California, San Francisco School of Dentistry predoctoral dental clinic in terms of caries risk level assignment using the caries risk assessment (CRA) as part of the Caries Management by Risk Assessment (CAMBRA) concept. This research was done in part to determine if additional training and calibration were needed for these faculty members. The study tested the reliability and reproducibility of the caries risk levels assigned by different clinical teachers who completed CRA forms for simulated patients. In the first step, five clinical teachers assigned caries risk levels for thirteen simulated patients. Six months later, the same five plus an additional nine faculty members assigned caries risk levels to the same thirteen simulated and nine additional cases. While the intra-examiner reliability with weighted kappa strength of agreement was very high, the inter-examiner agreements with a gold standard were on average only moderate. In total, 20 percent of the presented high caries risk cases were underestimated at caries levels too low, even when obvious caries disease indicators were present. This study suggests that more consistent training and calibration of clinical faculty members as well as students are needed.

    2009-03-24

    In an effort to locate potential law enforcement-related standards that support incident management, a team from the Pacific Northwest National Laboratory (PNNL) contacted representatives from the National Institute of Standards-Office of Law Enforcement Standards (NIST-OLES), National Institute of Justice (NIJ), Federal Bureau of Investigation (FBI), Secret Service, ASTM International committees that have a law enforcement focus, and a variety of individuals from local and regional law enforcement organizations. Discussions were held with various state and local law enforcement organizations. The NIJ has published several specific equipment-related law enforcement standards that were included in the review, but it appears that law enforcement program and process-type standards are developed principally by organizations that operate at the state and local level. Input is provided from state regulations and codes and from external non-government organizations (NGOs) that provide national standards. The standards that are adopted from external organizations or developed independently by state authorities are available for use by local law enforcement agencies on a voluntary basis. The extent to which they are used depends on the respective jurisdictions involved. In some instances, use of state and local disseminated standards is mandatory, but in most cases, use is voluntary. Usually, the extent to which these standards are used appears to depend on whether or not jurisdictions receive certification from a “governing” entity due to their use and compliance with the standards. In some cases, these certification-based standards are used in principal but without certification or other compliance monitoring. In general, these standards appear to be routinely used for qualification, selection for employment, and training. In these standards, the term “Peace Officer” is frequently used to refer to law enforcement personnel. This technical review of national law

    The Department of Energy (DOE) is constructing the Waste Treatment and Immobilization Plant (WTP) at the Hanford site in Washington to treat and immobilize approximately 114 million gallons of high level radioactive waste (after all retrievals are accomplished). In order for the WTP to be designed and operated successfully, close coordination between the WTP engineering, procurement, and construction contractor, Bechtel National, Inc. and the tank farms operating contractor (TOC), Washington River Protection Solutions, LLC, is necessary. To develop optimal solutions for DOE and for the treatment of the waste, it is important to deal with the fact that two different prime contractors, with somewhat differing contracts, are tasked with retrieving and delivering the waste and for treating and immobilizing that waste. The WTP and the TOC have over the years cooperated to manage the technical interface. To manage what is becoming a much more complicated interface as the WTP design progresses and new technical issues have been identified, an organizational change was made by WTP and TOC in November of 2011. This organizational change created a co-located integrated project team (IPT) to deal with mutual and interface issues. The Technical Organization within the One System IPT includes employees from both TOC and WTP. This team has worked on a variety of technical issues of mutual interest and concern. Technical issues currently being addressed include: - The waste acceptance criteria; - Waste feed delivery and the associated data quality objectives (DQO); - Evaluation of the effects of performing a riser cut on a single shell tank on WTP operations; - The disposition of secondary waste from both TOC and WTP; - The close coordination of the TOC double shell tank mixing and sampling program and the Large Scale Integrated Test (LSIT) program for pulse jet mixers at WTP along with the associated responses to the Defense Nuclear Facilities Safety Board (DNFSB) Recommendation

    Full Text Available This article consists of a case study regarding curriculum management practices of pedagogical coordinators in schools in Araucania area. The study aims to reveal technical/instrumental rationality, control and power mechanisms that underlie the curriculum management practices of such pedagogical coordinators of schools in Araucania region. A descriptive qualitative design based on the constructionist grounded theory and the constant comparative method is considered. Subjects studied included 12 technical leaders and 22 teachers from Araucania schools. Techniques for collecting information were semi-structured interview and texts for reading. Four categories rose from axial coding. Findings reveal that the teaching process is reduced to an instructional process. Furthermore, there is no uniformity of criteria regarding general functions that must be met. In the same extent, activity coordination is centered on bureaucratic administrative aspects, with main focus on task control. Regulations, programs and educational projects are used as control mechanisms. In addition, absence of spaces for professional discussion of pedagogical work and for constructive criticism is envisioned. This study concludes that pedagogical coordination practices are geared from an “instrumental rationality”, anchored in technical management set up in control and power.

    Full Text Available Objective: To assess the caries risk factors of preschool aged children. Methods: Data was collected from a sample of 85 preschool children and their mothers. An interview, and a clinical and microbiology assessment was included in this study. Clinical examinations were performed to measure the dental caries experience and plaque visibility of the children and mothers. The presence and levels of Mutans Streptococci (MS in the saliva was measured using a commercial kit by Dentocult SM and evaluated using the manufacturer’s chart. Results: Sixty-five children had a high risk of caries (76.5%, 12.9% had a low risk, and 10.6% had a moderate risk of caries. Active cavities were found in more than half of the mothers and children. The majority of the child subjects had a snacking habit between meals (85.9%. High risk scores of 2 and 3, indicating salivary levels of MS, was found in 41.1% of children. Fluoride exposure experienced by the study population was very limited. Conclusion: Results suggest that the majority of the population had a high caries risk. There was a high occurrence of teeth with cavities in children and active carious lesions in the mothers. There was a high frequency in snacking habits, the presence of plaque and bleeding gums, high levels of salivary MS, and low protective factors for the children. Results suggest that management of caries related factors are needed in order to prevent caries in the future.

    Few studies have been conducted to investigate the effects, if any, of specific medication used to manage the symptoms of attention deficit/hyperactivity disorder (ADHD) as a risk factor for dental caries. A reported side-effect of the medication is a reduction in saliva. Healthy saliva has been shown to play many important functions in the prevention of dental caries. The focus of this review is to determine if any evidence exists to confirm that stimulant medication used to treat the symptoms of ADHD in children increases the risk of dental caries by virtue of its effect on the reduction of salivary flow. A MEDLINE search was conducted for relevant studies. Search terms used were dental caries, attention deficit/hyperactivity disorder, ADHD, pharmacologic treatment of ADHD, stimulant medication, xerostomia, dry-mouth and saliva flow. Publication dates ranged from 2002 to 2012. Although dental caries prevalence has been found to be higher in children with ADHD, decreased salivary flow as a side-effect of pharmacological treatment does not appear to be responsible. Dental caries is a multi-factorial disease process. The most effective method of reducing dental caries in ADHD children is more frequent recare visits focusing on home plaque removal practices along with dietary counseling to reduce the consumption of cariogenic foods and drinks. This can only be accomplished with inclusion of the parent/guardian in the process. Copyright © 2014 The American Dental Hygienists’ Association.

    Full Text Available Background: Managing dental caries in young children is demanding due to the elusions present on the right diagnostic criteria for treatment. The present study evaluated the histological status of pulp tissues extracted from primary second molar with caries involvement. Histological findings are correlated with clinical and radiographic assessment. Materials and Methods: Simple experimental study was conducted on upper or lower second primary molars with occlusal (22 teeth or proximal (22 teeth dental caries. Selected children were below 6 years of age. Percentage of caries involvement, residual dentin thickness (RDT, radiographic assessment of interradicular and periapical areas, clinical caries depth and signs and symptoms are the parameters considered for comparing with the histological findings. The specimens were grouped based on the nature of the inflammatory process as acute or chronic. The data were analyzed by Student t-test to compare histological types of inflammation with clinical parameters. P value < 0.05 was considered as significant. Results: Four cases revealed severe acute inflammation in coronal and relatively mild acute inflammation in radicular pulp. In the rest of the specimen coronal and radicular pulp had similar acute or chronic inflammatory changes. Histological evidence of pulpitis correlated with dental caries depth of ≥80%, RDT of ≤1 mm, radiographic rarefactions in the interradicular regions and symptoms of pain. Conclusion: Primary second molars with more than two-third caries involvement with symptoms of pain histologically showed inflammation of both coronal and radicular pulp tissues in all cases.

    Obesity and dental caries have become increasingly prevalent challenges to public health. Research results into the relationship between obesity and dental caries in children have been mixed and inconclusive. The aim of this review and meta-analysis was to provide evidence to quantify the relationship between obesity and dental caries in children using a systematic approach. A systematic search for papers between 1980 and 2010 addressing childhood obesity and dental caries was conducted and a random effects model meta-analysis applied. Fourteen papers met the selection criteria. Overall, a significant relationship between childhood obesity and dental caries (effect size = 0.104, P = 0.049) was found. When analysed by dentition type (primary versus permanent), there was a nonsignificant association of obesity and dental caries in permanent and primary dentitions, yet on accounting only for standardized definitions for assessment of child obesity using body mass index, a strong significant relationship was evident in children with permanent dentitions. Moderating for study country of origin (newly 'industrialized' versus industrialized) showed a significant relationship between obesity and dental caries in children from industrialized but not newly industrialized countries. Cofactors such as age and socioeconomic class were significant moderators. Future analysis should investigate these confounding variables, helping shape the future of obesity management programmes and oral health interventions, through determining common risk factors. © 2012 John Wiley & Sons A/S.

    Highlights: • We developed a socio-technical commercial building energy management system. • It was designed for directly engaging and connecting building occupants via feedback. • We collected an array of clickstream data for internal design validation. • A pilot study validated its ability to drive energy savings in commercial buildings. - Abstract: Commercial buildings represent a significant portion of energy consumption and environmental emissions worldwide. To help mitigate the environmental impact of building operations, building energy management systems and behavior-based campaigns designed to reduce energy consumption are becoming increasingly popular. In this paper, we describe the development of a modular socio-technical energy management system, BizWatts, which combines the two approaches by providing real-time, appliance-level power management and socially contextualized energy consumption feedback. We describe in detail the physical and virtual architecture of the system, which simultaneously engages building occupants and facility managers, as well as the main principles behind the interface design and component functionalities. A discussion about how the data collection capabilities of the system enable insightful commercial building energy efficiency studies and quantitative network analysis is also included. We conclude by commenting on the validation of the system, identifying current system limitations and introducing new research avenues that the development and deployment of BizWatts enables

    Dental caries (tooth decay) is an infectious disease. Its etiology is not fully understood from the microbiological perspective. This study characterizes the diversity of microbial flora in the saliva of children with and without dental caries. Children (3–4 years old) with caries (n = 20) and without caries (n = 20) were recruited. Unstimulated saliva (2 mL) was collected from each child and the total microbial genomic DNA was extracted. DNA amplicons of the V3-V4 hypervariable region of the bacterial 16S rRNA gene were generated and subjected to Illumina Miseq sequencing. A total of 17 phyla, 26 classes, 40 orders, 80 families, 151 genera, and 310 bacterial species were represented in the saliva samples. There was no significant difference in the microbiome diversity between caries-affected and caries-free children (p > 0.05). The relative abundance of several species (Rothia dentocariosa, Actinomyces graevenitzii, Veillonella sp. oral taxon 780, Prevotella salivae, and Streptococcus mutans) was higher in the caries-affected group than in the caries-free group (p caries-free children than in caries-affected children (p caries-free and caries-affected children were similar. Salivary counts of certain bacteria such as R. dentocariosa and F. periodonticum may be useful for screening/assessing children’s risk of developing caries. PMID:27898021

    2013-01-01

    Background: Dental caries is an infectious disease of microbiologic origin resulting in destruction and loss of tooth structure and is related to every speciality of dentistry. Many studies have been carried out to identify the causative factors, methods of prevention, and treatment of dental caries. Ameloglyphics is the study of enamel rod end patterns. These patterns have been found to be unique to individual teeth of the same individual and also to different individuals. A possible correlation between the type of enamel rod end pattern and the occurrence of dental caries might help in predicting caries susceptibility of an individual and implementation of preventive measures. This is a simple and easy method cutting short elaborate methods currently in use and can be invaluable in caries prevention. Objective: This study is aimed at ascertaining the possibility of a correlation between enamel rod end patterns and occurrence of dental caries, which might help in identifying predisposition to dental caries. Materials and Methods: Thirty carious and 30 noncarious teeth were used to obtain enamel rod end patterns. Occurrence of any particular pattern in either of the study groups, which might affect the predisposition of teeth to dental caries was analyzed. Results: No particular rod end pattern was found in teeth affected by dental caries. Also, no particular pattern was found to be unique to teeth not affected by dental caries. PMID:24250075

    Full Text Available The technology advance in recent years determines the need of construction of modern appliances for early diagnosis of dental caries, which are categorized by great precision, non-invasiveness, easy usage and wide availability. Such non-invasive and accurate tool for diagnostics of caries is Caries Detector (LED, Bulgarian product by “Optica Laser”. The detector emits a specific wavelength of near ultraviolet light, which causes fluorescence to porphyrins - metabolic products of the life cycle of caries-inducing bacteria. The purpose of the study is piloting a new diagnostic tool for detection and monitoring of caries excavation based on fluorescence - LED UV caries detector of company “Optica laser”. Subjected to examination by caries indicator dye and UV caries detector were sixty permanent teeth with deep dentine caries. Two methods were used to assess the dentin caries - UV fluorescence detector of “Optica Laser” and staining with caries indicator - dye (Sable ™ Seek®. It was found that among all sixty teeth, the fields, closed by margins of carious process overlap. Fifty-four of tested teeth has shown bigger field of images with staining method and six - smaller in comparison to the fluorescent method. Ultraviolet fLuorescence caries detector of “Optica Laser” company is affordable and easy applicable method for controlled excavation of dentine caries. The detector can be used in daily dental practice equally with other methods. The unit has a number of advantages - non-invasiveness, lack of interaction with tooth structures, speed, reliability, efficiency, predictability and repeatability of results.

    The Preferred Upstream Management Practices (PUMP) project, a two-year study sponsored by the United States Department of Energy (USDOE), had three primary objectives: (1) the identification of problems, problematic issues, potential solutions and preferred practices related to oil production; (2) the creation of an Appalachian Regional Council to oversee and continue this investigation beyond the end of the project; and (3) the dissemination of investigative results to the widest possible audience, primarily by means of an interactive website. Investigation and identification of oil production problems and preferred management practices began with a Problem Identification Workshop in January of 2002. Three general issues were selected by participants for discussion: Data Management; Reservoir Engineering; and Drilling Practices. At the same meeting, the concept of the creation of an oversight organization to evaluate and disseminated preferred management practices (PMP's) after the end of the project was put forth and volunteers were solicited. In-depth interviews were arranged with oil producers to gain more insight into problems and potential solutions. Project members encountered considerable reticence on the part of interviewees when it came to revealing company-specific production problems or company-specific solutions. This was the case even though interviewees were assured that all responses would be held in confidence. Nevertheless, the following production issues were identified and ranked in order of decreasing importance: Water production including brine disposal; Management of production and business data; Oil field power costs; Paraffin accumulation; Production practices including cementing. An number of secondary issues were also noted: Problems associated with Enhanced Oil Recovery (EOR) and Waterflooding; Reservoir characterization; Employee availability, training, and safety; and Sale and Purchase problems.

    Data sourcesMedline, Embase, Cochrane Central and grey literature, complemented by cross-referencing from bibliographies. Diagnostic reviews were searched using the Medion database.Study selectionStudies reporting on the accuracy (sensitivity/specificity) of radiographic detection of primary carious lesions under clinical (in vivo) or in vitro conditions were included. The outcome of interest was caries detection using radiographs. The study also assessed the effect of the histologic lesion stage and included articles to assess the differences between primary or permanent teeth, if there had been improvements recently due to technical advances or radiographic methods, or if there are variations within studies (between examiners or applied radiographic techniques).Data extraction and synthesisData extraction was done by one reviewer first, using a piloted electronic spreadsheet and repeated independently by a second reviewer. Consensus was achieved by discussion. Data extraction followed guidelines from the Cochrane Collaboration. Risk of bias was assessed using QUADAS-2. Pooled sensitivity, specificity and diagnostic odds ratios (DORs) were calculated using random effects meta-analysis. Analyses were performed separately for occlusal and proximal lesions. Dentine lesions and cavitated lesions were analysed separately.Results947 articles were identified with the searches and 442 were analysed full text. 117 studies (13,375 teeth, 19,108 surfaces) were included. All studies were published in English. 24 studies were in vivo and 93 studies were in vitro. Risk of bias was found to be low in 23 and high in 94 studies. The pooled sensitivity for detecting any kind of occlusal carious lesions was 0.35 (95% CI : 0.31/40) and 0.41 (0.39/0.44) in clinical and in vitro studies respectively while the pooled specificity was 0.78 (0.73/0.83) and 0.70 (0.76/0.84).

  14. Caries Detection Methods Based on Changes in Optical Properties between Healthy and Carious Tissue

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available A conservative, noninvasive or minimally invasive approach to clinical management of dental caries requires diagnostic techniques capable of detecting and quantifying lesions at an early stage, when progression can be arrested or reversed. Objective evidence of initiation of the disease can be detected in the form of distinct changes in the optical properties of the affected tooth structure. Caries detection methods based on changes in a specific optical property are collectively referred to as optically based methods. This paper presents a simple overview of the feasibility of three such technologies for quantitative or semiquantitative assessment of caries lesions. Two of the techniques are well-established: quantitative light-induced fluorescence, which is used primarily in caries research, and laser-induced fluorescence, a commercially available method used in clinical dental practice. The third technique, based on near-infrared transillumination of dental enamel is in the developmental stages.

This study was done to determine the genetic aspect involved in the occurrence of dental caries through a cost-effective means, which can be used in field studies. 550 kindergarten school children in the age group 3-6 years were examined during a school examination camp. Of these, only 336 children were included in the study. They were divided into four groups as follows: caries-free males (df score=0), caries-free females, caries males (df score≥10), caries females. The handprints of each child were taken and the frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted. Separate df scores were recorded. SPSS software and test of proportions were used for the analysis. Handprints of caries-free children, especially females, showed maximum ulnar loops. The caries group showed maximum occurrence of whorls (r=2:1), which were more prevalent in females on the left hand 3rd digit than in males where the whorls were found on the right hand 3 rd digit, and also low total ridge count, especially in males.

  20. The relationship between diet and Dental Caries

    Dental caries is a disease of multifactorial etiology and results from a complex interaction between both cariogenic and protective influences acting on the teeth. Though diet plays a major role in the causation of dental caries it has been a common mistake to over-simplify the relationship. Dietary manipulation is also extremely difficult to achieve thus limiting its role in the prevention of caries. Accordingly, alternative preventive measures such as the use of fissure sealants and fluoride which enhance the resistance of the host to disease and are of proven efficacy are more likely to be successful in the control and prevention of dental caries.

    Dental caries is an irreversible microbial disease of the calcified tissues of the teeth and it has a multifactorial origin. In India, the dental caries prevalence in 35-44 year olds was reported to be 80-95% in a DCI survey. Among the elderly in the 65-74 years age group, the DCI survey reported the caries prevalence to be about 70%, while the present survey reported it to be 51- 95% in various states. Surveys which were done on school children in India showed a carie prevalence of approximately 58%.Among the U.S. population, a survey showed an incidence of 93.8% in adults with either past or present coronal caries and an incidence of 45.3% in children 23. In countries like Brazil and China, it is reaching epidemic proportions. Thus, more effective public-health measures are needed to combat dental caries. Mutans streptococci is one of the main microorganisms which are associated with the aetiology of dental caries. Preclinical studies of immunological interventions have shown that the disease can be interrupted. Clinical trials have indicated that a mucosal immune response to Streptococcus mutans crucial antigens can influence the pathogenesis of dental caries. The dental caries vaccine, when it is used in appropriate individuals at the appropriate time, can reduce the reemergence of the disease.

    Technical assistance (TA) is a common component of health system strengthening interventions. This type of intervention is too often designed and evaluated according to a logic that fails to take into account social complexity. Actors' perceptions are one element of this complexity. This article presents a study conducted in the Democratic Republic of Congo designed to identify perceptions concerning two types of technical support providers for health system strengthening: long-term technical assistants (agents of development agencies) and provincial technical advisors (agents of the Ministry of Health). Interviews were conducted with an innovative tool inspired by the principles of systems thinking. Interviewees were actors involved in a TA intervention in the province of Bandundu. Their expectations regarding TA providers were identified in terms of personal characteristics (knowledge, know-how and interpersonal skills), roles, and styles of interaction for capacity building ("interventionist/ prescriptive axes"). Interviewees emphasized the importance of mutual learning and the quality of interactions, which depends on TA provider's interpersonal skills and mutual willingness. Perceptions of TA provider's characteristics tend to be similar, but several differences were observed concerning the expectations about the roles of TAs, and the style that should be adopted for capacity building. Ignoring these differences in expectations may be a threat to the effectiveness of TA.

    Caries management requires a complete oral examination and an accurate caries risk assessment (CRA). Performing Caries Management by Risk Assessment (CAMBRA) is inefficient when the caries risk level assignment is incorrect. The aim of this study was to evaluate the ability of faculty members and students at one U.S. dental school to correctly assign caries risk levels for 22 CRA cases, followed by calibration with guidelines on how to use the CRA form and a post-calibration test two months after calibration. Inter-examiner reliability to a gold standard (consensus of three experts) was assessed as poor, fair, moderate, good, and very good. Of the 162 students and 125 faculty members invited to participate, 13 students and 20 faculty members returned pre-calibration tests, for response rates of 8% and 16%, respectively. On the post-calibration test, eight students and 13 faculty members participated for response rates of 5% and 10%, respectively. Without guidelines and calibration, both faculty members and students when evaluated as one group performed only poor to fair in assigning correct caries risk levels. After calibration, levels improved to good and very good agreements with the gold standard. When faculty and students were evaluated separately, in the pre-calibration test they correctly assigned the caries risk level on average in only one-quarter of the cases (students 24.1%±13.3%; faculty 23.6%±17.5%). After calibration, both groups significantly improved their correct assignment rate. Faculty members (73.8% correct assignments) showed even significantly higher correct assignment rates than students (47.7% correct assignments). These findings suggest that calibration with a specific set of guidelines improved CRA outcomes for both the faculty members and students. Improved guidelines on how to use a CRA form should lead to improved caries risk assessment and proper treatment strategy for patients.

    To describe the learning process of family carers who manage technical health procedures (such as enteral tube feeding, intravenous therapy, dialysis or tracheostomy care) at home. Increasingly, complex procedures are being undertaken at home but little attention has been paid to the experiences of family carers who manage such procedures. Grounded theory, following Charmaz's constructivist approach. Interviews with 26 family carers who managed technical health procedures and 15 health professionals who taught carers such procedures. Data collection took place in New Zealand over 19 months during 2011-2013. Grounded theory procedures of iterative data collection, coding and analysis were followed, with the gradual development of theoretical ideas. The learning journey comprised three phases: (1) an initial, concentrated period of training; (2) novice carers taking responsibility for day-to-day care of procedures while continuing their learning; and (3) with time, experience and ongoing self-directed learning, the development of expertise. Teaching and support by health professionals (predominantly nurses) was focussed on the initial phase, but carers' learning continued throughout, developed through their own experience and using additional sources of information (notably the Internet and other carers). Further work is needed to determine the best educational process for carers, including where to locate training, who should teach them, optimal teaching methods and how structured or individualized teaching should be. Supporting carers well also benefits patient care. © 2016 John Wiley & Sons Ltd.

  14. The development and validation of a new technology, based upon 1.5% arginine, an insoluble calcium compound and fluoride, for everyday use in the prevention and treatment of dental caries.

    Science.gov (United States)

    Cummins, D

    2013-08-01

    This paper briefly discusses caries prevalence, the multi-factorial nature of caries etiology, caries risk and the role and efficacy of fluoride. The paper also highlights research on bacterial metabolism which provided understanding of the mouth's natural defenses against caries and the basis for the development of a new technology for the everyday prevention and treatment of caries. Finally, evidence that the technology complements and enhances the anti-caries efficacy of fluoride toothpaste is summarized. Global data show that dental caries is a prevalent disease, despite the successful introduction of fluoride. Caries experience depends on the balance between consumption of sugars and oral hygiene and the use of fluoride. Three scientific concepts are fundamental to new measures to detect, treat and monitor caries: (1) dental caries is a dynamic process, (2) dental caries is a continuum of stages from reversible, pre-clinical to irreversible, clinically detectable lesions, and (3) the caries process is a balance of pathological and protective factors that can be modulated to manage caries. Fluoride functions as a protective factor by arresting and reversing the caries process, but fluoride does not prevent pathological factors that initiate the process. A novel technology, based upon arginine and an insoluble calcium compound, has been identified which targets dental plaque to prevent initiation of the caries process by reducing pathological factors. As the mechanisms of action of arginine and fluoride are highly complementary, a new dentifrice, which combines arginine with fluoride, has been developed and clinically proven to provide superior caries prevention.

    The French market of centralized space heating regulation remains practically stagnant with important disparities with respect to the type of heating: electrical or hot water. This trend should change according to the variations of the domestic market which is linked, to some extent, to the opening of energy markets. However, two points remain certain: the French dwellings remain under-fitted in the domain of regulation systems, and the installations and technical management systems of tertiary buildings are implemented with the minimum possibilities.

    To produce a working clinical protocol for pulp therapy techniques in the extensively carious primary molar. The International Agency for Research on Cancer has recently classified formaldehyde as carcinogenic to human beings. As such, a medicament that can be used to replace formocresol in clinical practice should be identified. Part I of this paper explored the currently available alternative interventions and materials to formocresol in the form of a narrative review following an extensive literature search. Part II now presents the formation of a specialist group to establish an evidence-based protocol, for the management of the extensively carious primary molar. A protocol and key points document have been developed to assist clinicians in their treatment planning. Areas for further postgraduate training are identified.

    Routine work in nuclear medicine requires the careful elution of radioactivity and its subsequent, storage and handling. Though all effort is maintained to prevent any “spill” of this radioactivity, accidents are bound to happen. The response to this spill is a methodically worked out a plan that is written and adopted as a “standard operating procedure.” This protocol is taught to all involved in the area of working as a mock drill/apprenticeship model. No formal evaluation of learning is in place except for the mock drills. The objectively structured assessment of technical skills (OSATS) is a variation on the Objective Structured Clinical Examination, which is a form of workplace based assessment. The OSATS is cited in the Accreditation Council of Graduate Medical Education evaluation toolbox on the website as the most desirable evaluation tool for the patient care topics. It is the objective of this paper is to introduce the “OSATS” for teaching, and assessment of the learning, of the protocol for the management of radioactive spill. As a review of the literature on the subject failed to reveal any such teaching protocol/material/document for this important technical skill, we hope that it may act as a landmark for the development of teaching and assessment of other technical skills also

    1997-01-01

    The technical specifications for the composition of nuclear fuels and materials used in Canada's CANDU reactors have been developed by AECL and materials manufacturers, taking into account considerations specific to their manufacture and the effect of minor impurities on fuel behaviour in reactor. Nitrogen and chlorine are examples of UO 2 impurities, however, where there is no technical specification limit. These impurities are present in the source materials or introduced in the fabrication process and are neutron activated to 14 C and 36 C1, which after 129 I , are the two most significant contributors to dose in safety assessments for the disposal of used fuel. For certain impurities, environmental factors, particularly the safety of the disposal of used fuels, should be taken into consideration when deriving 'allowable' impurity limits for nuclear fuel materials.

  5. The oral microbiome and the immunobiology of periodontal disease and caries

    2015-01-01

    The composition of the oral microbiome differs from one intraoral site to another, reflecting in part the host response and immune capacity at each site. By focusing on two major oral infections, periodontal disease and caries, new principles of disease emerge. Periodontal disease affects the soft tissues and bone that support the teeth. Caries is a unique infection of the dental hard tissues. The initiation of both diseases is marked by an increase in the complexity of the microbiome. In periodontitis, pathobionts and keystone pathogens such as Porphyromonas gingivalis appear in greater proportion than in health. As a keystone pathogen, P. gingivalis impairs host immune responses and appears necessary but not sufficient to cause periodontitis. Historically, dental caries had been causally linked to Streptococcus mutans. Contemporary microbiome studies now indicate that singular pathogens are not obvious in either caries or periodontitis. Both diseases appear to result from a perturbation among relatively minor constituents in local microbial communities resulting in dysbiosis. Emergent consortia of the minor members of the respective microbiomes act synergistically to stress the ability of the host to respond and protect. In periodontal disease, host protection first occurs at the level of innate gingival epithelial immunity. Secretory IgA antibody and other salivary antimicrobial systems also act against periodontopathic and cariogenic consortia. When the gingival immune response is impaired, periodontal tissue pathology results when matrix metalloproteinases are released from neutrophils and T cells mediate alveolar bone loss. In caries, several species are acidogenic and aciduric and appear to work synergistically to promote demineralization of the enamel and dentin. Whereas technically possible, particularly for caries, vaccines are unlikely to be commercialized in the near future because of the low morbidity of caries and periodontitis. PMID:25447398

    To compare proximal caries depth between conventional film images, unenhanced and enhanced storage phosphor plate images. Bitewing radiographs were taken on 100 patients presenting for Conservative and Periodontal treatment. Only one bitewing was taken on a patient either the right or left hand side of the patient A DenOptics storage phosphor plate and size 3 Kodak Insight film were simultaneously placed into a Rinn bitewing holder. The Insight film was placed behind the phosphor plate. Both were simultaneously exposed to radiation. The unenhanced phosphor plate images were copied four times. Contrast and brightness were either increased or decreased on the copied images. A five point scale was chosen for proximal caries depth: 0--sound, 1--caries in enamel, 2--caries reaching dentino-enamel junction, 3--caries into dentine, 4--caries in a restored area. The bitewing images were evaluated by 4 clinicians. Images with technical errors were excluded from the study. Altogether 1848 tooth surfaces were evaluated of which 136 surfaces were excluded due to technical errors. The results show that for the detection of proximal caries there is no significant difference in accuracy between unenhanced storage phosphor plate and Kodak Insight film images (p > 0.001). When decreasing both contrast and brightness there was no significant difference in diagnostic accuracy (p > 0.001) between unenhanced and enhanced storage phosphor plate images. More surfaces were analyzed for caries into the dentine on the enhanced images when both contrast and brightness were increased. Although contrast-enhanced and brightness-enhanced images retween conventional film, unenhanced and enhanced images.

    Japanese safety regulatory body, that is, Nuclear and Industrial Safety Agency (NISA) has been financially supporting safety researches conducted by academia for obtaining ageing management technique and knowledge. There are two five-year projects. One was executed from 2006 FY(Fiscal Year) to 2010 FY whose objective was 'Improve the technical information basis in order to utilize knowledge as well as information related to aging management and maintenance of NNPs. The other one has been executed since 2011 FY which focuses on the concept of system safety of NNPs, that is, not only focuses on aging management of important components' degradation phenomena but also on safety management of total plant system. 'Strategy Map for Aging Management' has been developed where the internal and external conditions of nuclear safety are analyzed, the priority of safety research themes is clarified and roadmaps of the researches are drawn up. The research themes picked up in the NISA projects are consistent with the strategy map and its rolling activity plays a role of PDCA cycle's driving force of NISA projects. (author)

    Scientific advances in cariology in the past 150 years have led to the understanding that dental caries is a chronic, dietomicrobial, site-specific disease caused by a shift from protective factors favoring tooth remineralization to destructive factors leading to demineralization. Epidemiologic data indicate that caries has changed in the last century; it now is distributed unequally in the U.S. population. People who are minorities, homeless, migrants, children with disabilities and of lower socioeconomic status suffer from the highest prevalence and severity of dental caries. Scientific advances have led to improvements in the prevention, diagnosis and treatment of dental caries, but there is a need for new diagnostic tools and treatment methods. and Future management of dental caries requires early detection and risk assessment if the profession is to achieve timely and cost-effective prevention and treatment for those who need it most. Dental professionals look forward to the day when people of all ages and backgrounds view dental caries as a disease of the past.

    Full Text Available Early Childhood Caries (ECC is a specific form of severe dental caries that affects infants and young children. ECC progresses rapidly in those who are at high risk, and often goes untreated. Children experiencing caries as infants or toddlers have a much greater probability of subsequent caries in both primary and permanent dentitions. This case showed management holistic care for children with ECC.A five year old boy patient accompanied with her parents were reported to the Pedodontic Clinic Padjadjaran University Dental Hospital with a chief complaint of decayed upper anterior teeth and pain in the molar teeth. Clinical examinations found dental caries almost all teeth in the maxilla and mandible. Based on panoramic radiograph, treatments that can be done are strip crown glass ionomer restorations, pulp treatments, extractions and fixed space maintainer. Patients diagnosed with severe ECC, patient and parents described on this type of caries. During treatment the patient was given oral hygiene instruction and recommend daily use of tooth mouse. After all treatment were completed, fluoride topical, and fissure sealants, recall check up after three months was scheduled. Holistic care needed in handling children with ECC.

    The publication explains, by means of specific measures, the management of aging in technical facilities as practiced in the plants of E.ON Kernkraft GmbH. First, the historical background is outlined and the reasons for introducing management of aging in order to limit and control factors influencing the lifetime of nuclear power plants are described. This is followed by a definition of management of aging in important safety-related facilities as against lifetime management of technical systems relevant to plant availability. This is the context in which the scope of the survey of continuous management of aging is defined in respect of physical aging. A classification is then made in accordance with the staggered requirements to be met in the quality of technical facilities. On the basis of the quality to be assured, the different component groups are assigned corresponding operational measures and explained. These continuous measures extend from failure-oriented maintenance to preventive maintenance to the integrity concept for technical installations. To document the findings and evaluate the effectiveness of the measures taken, the integration of the process is described and reference is made to continuous optimization according to PDCA principles. The explicit introduction of the process of management of aging creates a platform which allows a documentation to be accumulated of the manifold and comprehensive measures taken to control phenomena of aging in technical installations.

    Full Text Available Background: There is a lack of consensus regarding the relationship between the risk of dental caries and asthma in the child population. Most studies concluded that asthmatic children are at risk of dental caries from the disease status or its pharmacotherapy. The objectives of this study werer to assess the dental caries status of asthmatic patients in the age group of 3-14 years and to examine the possible association of these conditions to various aspects of bronchial asthma and its management. Materials and Methods: The present study is a hospital-based case-control cross-sectional study. One hundred and five asthmatic patients were studied. The children were examined for their dental caries status, and the scores were compared with age-, gender- and socioeconomic status-matched group of 112 nonasthmatic patients selected randomly from public schools (control group. Caries lesions were assessed using decayed, missing, filled teeth/decayed, missing, and filled surfaces (DMFT/DMFS and dmft/dmfs index according to the WHO criteria (1987. Parents or guardians provided information about oral hygiene and dietary habits by direct interview. Asthma-related data (type and form of medication, severity and duration of asthma were collected from medical records and/or parental interview. Results: The mean age of asthmatics was (7.7 ± 3.5 years and (7.8 ± 3.5 for nonasthmatics. The results showed significantly higher prevalence and severity of dental caries among asthmatic group. As comparing asthmatic children using β2-agonists to those children using β2-agonists and corticosteroids, the results revealed that there were no statistically significant differences in caries index between the two groups. In their primary teeth, children with severe asthma had higher dmft/dmfs than children with moderate and mild asthma unlike in the permanent teeth. Form of medication used - an inhaler or a noninhaler combination (syrup and tablets - had no effect on

    The purpose of the experiment was to evaluating the diagnostic ability of dental caries detection using digital subtraction in the artificial caries activity model. Digital radiographs of five teeth with 8 proximal surfaces were obtained by CCD sensor (Kodak RVG 6100 using a size no.2). The digital radiographic images and subtraction images from artificial proximal caries were examined and interpreted. In this study, we proposed novel caries detection method which could diagnose the dental proximal caries from single digital radiographic image. In artificial caries activity model, the range of lesional depth was 572-1,374 μm and the range of lesional area was 36.95-138.52 mm 2 . The lesional depth and the area were significantly increased with demineralization time (p<0.001). Furthermore, the proximal caries detection using digital subtraction radiography showed high detection rate compared to the proximal caries examination using simple digital radiograph. The results demonstrated that the digital subtraction radiography from single radiographic image of artificial caries was highly efficient in the detection of dental caries compared to the data from simple digital radiograph.

    Full Text Available Cariogram is a computer program that uses an algorithm to assess caries risk. Although the use of Cariogram has recently increased, little information is available regarding its effectiveness in adults. This study aimed to determine whether caries risk from Cariogram relates to caries experience in adults. One hundred and eighty Cariogram files were completed from patients aged ten to fifty-six years (mean: 23.28 years. Seven factors from the software were included from patient records to complete the Cariogram: caries experience, diet (content and frequency, stimulated salivary flow, hygiene index, related diseases and fluoride usage. The percentages of "chances of avoiding new lesions" (caries risk were obtained from Cariogram, and the subjects were classified into five risk groups. Results were compared for each variable with ANOVA, and a correlation between caries and Cariogram variables was calculated by Pearson's correlation coefficient. A multivariate regression model was also used. Only three patients were classified as low risk, and none were classified as very low risk. Thus, only the four upper quintiles were considered for the analysis, and the lower quintile was not considered in the study. Neither DMFT nor the number of lesions were significantly different among the Cariogram's risk categories (p > 0.05. Only diet content was significantly correlated with caries experience (p = 0.006. Caries lesions failed to correlate with any Cariogram variable (p > 0.05. Age, not sex or caries risk scores, showed a strong and positive association with DMFT (p < 0.01. Caries risk from Cariogram appears to be unrelated with caries experience or caries lesions in a high-caries adult population.

    2018-01-29

    Intensification of agriculture and ongoing urban sprawl exacerbate pressures on rivers. Small rivers in agricultural landscapes are especially exposed to excessive technical actions implemented in order to allow for harvesting river water for irrigation, draining agricultural water and receiving sewage. Regular dredging and macrophyte removal strongly interfere with the global need for preserving river biodiversity that allows agricultural lowland rivers to remain refuges for a variety of species, and-accordingly-to keep water bodies resilient for the benefit of society. In order to provide a comprehensive look at the influence of agricultural lowland river management on the ecological status of these water bodies, we conducted a literature review and a meta-analysis. For the structured literature review we selected 203 papers reflecting on the response of aquatic ecosystems to dredging and macrophyte management actions. The database of scientific contributions developed for our study consists of papers written by the authors from 33 countries (first authorship) addressing dredging, macrophyte removal, status of fish and macroinvertebrates as well as the general ecological status of lowland agricultural rivers. We revealed that 96% of the analyzed papers indicated unilateral, negative responses of aquatic ecosystems, particularly macroinvertebrates, ichthyofauna and macrophyte composition, to maintenance measures. We revealed that studies conducted in the European Union on the ecological status of rivers appeared to significantly increase in quantity after the implementation of the Water Framework Directive. Finally, we concluded that day-to-day management of lowland agricultural rivers requires revision in terms of compliance with environmental conservation requirements and the recurrent implementation of technical measures for river maintenance.

    This study focuses on the potential role of technical and institutional innovations for improving water management in a multi-user context in Burkina Faso. We focus on a system centered on three reservoirs that capture the waters of the Upper Comoé River Basin and servicing a diversity of users, including a sugar manufacturing company, a urban water supply utility, a farmer cooperative, and other downstream users. Due to variable and declining rainfall and expanding users’ needs, drastic fluctuations in water supply and demand occur during each dry season. A decision support tool was developed through participatory research to enable users to assess the impact of alternative release and diversion schedules on deficits faced by each user. The tool is meant to be applied in the context of consultative planning by a local user committee that has been created by a new national integrated water management policy. We contend that both solid science and good governance are instrumental in realizing efficient and equitable water management and adaptation to climate variability and change. But, while modeling tools and negotiation platforms may assist users in managing climate risk, they also introduce additional uncertainties into the deliberative process. It is therefore imperative to understand how these technological and institutional innovations frame water use issues and decisions to ensure that such framing is consistent with the goals of integrated water resource management.

  5. Radioactive waste management services. Safety and technical advisory services available from the IAEA

    International Nuclear Information System (INIS)

    2000-09-01

    This brochure provides updated information about the services and assistance the International Atomic Energy Agency (IAEA) is able to render, upon request by Member States, in the area of radioactive waste management. The ultimate objective is to ensure that all wastes are managed safely and in a way which protects both individual and the environment, now and in the future. The IAEA is the sole global international organization with the statutory authority to establish safety standards for the protection of health against exposure to ionizing radiation. These include safety standards for radioactive waste management. A comprehensive set of such standards is being established, and continuously updated, under the Agency's aegis, which lay out the requirements for the safe management of all types of radioactive waste. The Agency has a further statutory obligation ro provide for the application of these standards at the request of States. The safety of radioactive waste management is not attainable through safety standards alone but requires special technology. An additional function of the IAEA is thus to foster the transfer of technology among States, including the specific technology needed to ensure safe radioactive waste management

    The study sought to analyze the association between dental caries and obesity in Chinese children, and to investigate the protective and risk factors of dental caries. A total of 280 children aged 7-12 years voluntarily answered the caries examination and questionnaire. Caries was measured using the International Caries Detection and Assessment System. According to the Chinese body mass index, the participants were grouped overweight or normal-weight. The logistic regression model showed no correlation between dental caries and obesity. Drinking yogurt and chewing gum are protective factors, whereas oral breathing and genetic predisposition to caries are risk factors. Copyright © 2012 S. Karger AG, Basel.

  7. The management of radioactive wastes produced by radioisotope users. Technical addendum

    International Nuclear Information System (INIS)

    1966-01-01

    This Addendum contains detailed technical information on processes and procedures that are outlined in more general terms in the Code of Practice. The information is particularly relevant to the problem of handling the relatively small quantities of waste arising from the use of radionuclides in laboratories, hospitals and industry when no special facilities for radioactive waste treatment are available on site. The Addendum is directed toward providing the radioisotope user with the type and amount of information required for him to be able to assess the alternatives available to him in terms of his particular needs, develop a preliminary design of an optimum waste-handling system and get help and guidance in his search for more detailed information.

    To assess individuals' perception of dental caries, in order to explain how illness representations might influence their coping with the disease. Cross-sectional questionnaire study. 520 consecutive patients (aged ≥18 years) of the General Dentistry Clinic at Universidad Cooperativa de Colombia, Pasto, Colombia who had experienced dental caries. Illness perception of dental caries was assessed using the Illness Perception Questionnaire Revised (IPQ-R). The most frequent self-reported symptoms associated with dental caries were "toothache" (56.2%), "tooth sensitivity" (53.8%) and "mild to sharp pain when eating or drinking" (51.2%). The dimensions of illness perception were related to socio-economic status (SES). Symptoms of "loose or separating teeth" and "pus in your tooth" were associated with dental caries by low SES participants, while "bleeding while brushing, flossing or eating hard food" and "mild to sharp pain when eating or drinking something sweet, hot or cold" were related more to higher SES. Perceptions of caries were related to socioeconomic status. Interventions to promote health literacy in order to improve the capacity to obtain, process and understand basic oral health information could increase an early detection of caries.

    Pitts, N B

    2009-01-01

    This chapter deals with improving the detection, assessment, diagnosis and monitoring of caries to ensure optimal personalized caries management. This can be achieved by delivering what we have (synthesized evidence and international consensus) better and more consistently, as well as driving research and innovation in the areas where we need them. There is a need to better understand the interrelated pieces of the jigsaw that makes up evidence-based dentistry, i.e. the linkages between (a) research and synthesis, (b) dissemination of research results and (c) the implementation of research findings which should ensure that research findings change practice at the clinician-patient level. The current situation is outlined; it is at the implementation step where preventive caries control seems to have failed in some countries but not others. Opportunities for implementation include: capitalizing on the World Health Organization's global policy for improvement of oral health, which sets out an action plan for health promotion and integrated disease prevention; utilizing the developments around the International Caries Detection and Assessment System wardrobe of options and e-learning; building on initiatives from the International Dental Federation and the American Dental Association and linking these to patients' preferences, the wider moves to wellbeing and health maintenance. Challenges for implementation include the slow pace of evolution around dental remuneration systems and some groups of dentists failing to embrace clinical prevention. In the future, implementation of current and developing evidence should be accompanied by research into getting research findings into routine practice, with impacts on the behaviour of patients, professionals and policy makers.

  10. Diagnosis of Proximal Caries in Primary Molars with DIAGNOdent pen

    OpenAIRE

    Ermler, Romy

    2010-01-01

    Proximal surfaces, together with fissures, are the areas where most primary caries occur. Due to the anatomy of the deciduous molars, proximal caries cannot be detected at an early stage in crowded teeth by simply using a mirror and probe. Therefore, additional methods to find early proximal caries have to be used. KaVo uses laser fluorescence to detect caries. Originally, the DIAGNOdent devices were able to detect only occlusal caries (56, 61, 62, 65, 66). New results are now also available ...

    Dental caries is caused by a combination of infection and diet. This disease, if left untreated, may lead to pain, and impair the quality of life, nutritional status and development of young children. The objective was to investigate the association between snacking and caries in a population at high risk of dental caries. American preschool children (n = 1,206) were recruited in the offices of paediatricians. Data on sociodemographic characteristics, oral hygiene, breast-feeding, use of bottle and snacking were collected by questionnaire. Plaque presence, the number of teeth and their caries status (deft) were scored. The children sampled were 61% Black, 27% White and 10% Asian. Of the 1- to 2-, 2- to 3- and 3- to 4-year-old children, 93.8, 82.4 and 77.3% were caries free, and their mean caries scores were 0.16, 0.58 and 0.93, respectively. Multivariate partial least squares (PLS) modelling revealed plaque presence, lowest income, descriptors for tooth exposure time (number of teeth and age) and cariogenic challenge (total intake of sugar-containing snacks and chips/crisps, and chips intake with a sugar-containing drink) to be associated with more caries. These differences were also found in univariate analyses; in addition, children who continued breast-feeding after falling asleep had significantly higher deft values than those who did not. PLS modelling revealed that eating chips clustered with eating many sweet snacks, candies, popcorn and ice cream. We conclude that, in addition to the traditional risk indicators for caries - presence of plaque, sugar intake and socioeconomic status -, consumption of chips was associated with caries in young children.

    Keyes, Paul H; Rams, Thomas E

    An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. These observations further document the potential protective effects of dental calculus mineralization against dental caries.

    2018-04-01

    Earned value management (EVM) is a methodology for monitoring and controlling the performance of a project based on a comparison between planned and actual cost/schedule. This study proposes a concept of hybrid earned value management (H-EVM) that integrates the traditional EVM metrics with information on the technology readiness level. The proposed concept can reflect the progress of a project in a sensitive way and provides short-term perspective complementary to the traditional EVM metrics. A two-dimensional visualization on the cost/schedule status of a project reflecting both of the traditional EVM (long-term perspective) and the proposed H-EVM (short-term perspective) indices is introduced. A case study on the management of a new space launch vehicle development program is conducted to demonstrate the effectiveness of the proposed H-EVM concept, associated metrics, and the visualization technique.

    2004-01-01

    The paper presents the essentials of sound knowledge management, including NKM: capturing and storing relevant data; conversion of tacit knowledge to explicit knowledge; use information to develop knowledge; networking; building knowledge management culture. An overview is made of the various departments of the IAEA their role from the perspective of KM. It is stated that in addition to consolidating KM-related activities in the departments, there is a need to develop a central focal point, specially to devise strategies for meeting the expected shortages of young professionals and harmonizing and enhancing the training activities. Another area should be strengthening and modernizing INIS and national information services

    2007-04-24

    The importance and necessity for a fully developed and implemented National Incident Management System (NIMS) has been demonstrated in recent years by the impact of national events such as Hurricane Katrina in 2005. Throughout the history of emergency response to major disasters, especially when multiple response organizations are involved, there have been systemic problems in the consistency and uniformity of response operations. Identifying national standards that support the development and implementation of NIMS is key to helping solve these systemic problems. The NIMS seeks to provide uniformity and consistency for incident management by using common terminology and protocols that will enable responders to coordinate their efforts to ensure an efficient response.

    In Germany, caries of young people has been declining since the late 1980s, while the prevalence of early childhood caries has remained steady. Data from a number of regional studies suggest a current prevalence between 10% and 15%. However, there is a dearth of longitudinal observational study data on the risk of caries in the permanent teeth of persons who as children had to undergo comprehensive treatment for caries under intubation general anesthesia. The aim of this study was to compare caries experience in the permanent teeth of patients who had to undergo surgical treatment under general anesthesia as a result of non-compliance with caries treatment in early childhood with the experience of patients who did not develop caries at a young age. Analysis of the data revealed that severe caries experience during early childhood resulted in a more severe caries experience during adulthood (difference: 14.8 DMFS; p = 0.001). This increase in caries experience applied to both untreated and treated carious surfaces, and was also apparent in relation to tooth extractions. When compared with persons whose first teeth had been caries-free, patients with severe childhood caries experience tended to show poorer dental hygiene in relation to smooth (p < 0.06) and interproximal (p < 0.04) surfaces. Patients who had been non-compliant as young children were not found to suffer from dental anxiety as young adults. Patients in the treatment and control groups differed with regard to dental health. Aside from being statistically relevant, these differences also have implications for clinical dental practice.

  20. Introducing a Dental Caries Marking Software and Evaluate Radiologists’ Disagreement in Caries Detection Using this Software

    2015-03-01

    Full Text Available Statement of Problem: Bitewing radiograph is the main reference for diagnosis of proximal and recurrent caries. There is no software for gathering and analyzing radiologists’ opinion in the field of caries detection on digital bitewing radiograph (DBR. Objectives: The main aim of this study is to introduce the first windows application that could be used for marking caries on DBR. This software is called Dental Caries Marking Software (DCMS. The second aim is to create the first DBR caries dataset to be used for future software development projects in the field of automatic caries detection; also gathering and documenting the disagreements and critiques regarding DCMS. Materials and Methods: DCMS has been designed and implemented by the researchers of this study. This software is divided into two parts. The first part is DCMS writer that is used for gathering the user’s opinion and The second part is DCMS analyzer that is used for reading and analyzing the user’s opinion file. Eight radiologists with different experiences used DCMS for marking dental caries on 200 DBR, 50 of which were repeated twice for assessing the accuracy of each radiologist. Results: A total of 3833 points were marked by 8 users on 150 non repetitive DBR. Only 35 points were marked similarly by 8 users; in other words, 8 users totally agreed with 4% of the caries points. According to 50 repetitive DBR, the maximum accuracy of users was 69% and the minimum was 50%. Conclusions: There is significant debate over the diagnosis of caries on DBR; therefore, for unifying the radiologist’s opinions, the need for intelligent caries detection software is apparent. DCMS is useful software for gathering caries data. Moreover, the use of conventional display monitor has negative impacts on accurate diagnosis of caries on DBR.
