An Invitation To Multidisciplinary Education Training And Research

In the 21st century, major technological breakthroughs are more likely to occur at the interfaces of disciplines. Biophotonics integrates four major technologies lasers, photonics, nanotechnology, and biotechnology. Fusion of these technologies truly offers a new dimension for both diagnostics and therapy. Biophotonics creates many opportunities for chemists, physicists, engineers, physicians, dentists, health-care personnel, and biomedical researchers. The

Preface to the Second Edition

Although minor changes and corrections have been made throughout the book, major changes have been limited to Chap. 4. The reason is that the theory presented in Chaps. 2 and 3 is basically complete and does not need any further modifications, except that the discussion on laser-induced interstitial thermotherapy (LITT) in Sect. 3.2 has been extended by the technique of a multi-fiber treatment. On the other hand, the contents of Chap. 4 - the chapter on applications - strongly depend on the current state of the art. The second edition of this book covers all applications addressed in the first edition plus novel techniques for refractive corneal surgery and the treatment of caries. The success in refractive corneal surgery has significantly increased since the introduction of laser in situ keratomileusis (LASIK) described in Sect. 4.1. The quality of caries removal can be improved with the application of ultrashort laser pulses with durations in the femtosecond range...

Word of Advice to Providers

Physicians and dentists should not lease office space prior to having a space planner prepare a program (list of rooms, sizes, and critical adjacencies) and a summary of total square footage required. This would be analogous to shopping for a suit of clothes without knowing what size one wears. In fact, if you are considering two or three alternative spaces, the fee invested in a program and schematic space plan will pay huge rewards in demonstrating which space most appropriately lends itself to your practice's needs. In fact, a smaller space with specific dimensions or a specific configuration may accom

Management Of Missing Teeth

Teeth are commonly absent from the dental arch either congenitally or as a result of disease, of which caries and periodontal breakdown are the most common. While it is not axiomatic that a missing tooth should always be replaced, there are many occasions where this is desirable to improve appearance, masticatory function or speech, or sometimes to prevent harmful changes in the dental arches, such as the overeruption or tilting drifting of teeth. Tooth loss is also followed by resorption of the alveolar bone, which exacerbates the resultant tissue deficit.

Dyskeratosis Congenita

Dyskeratosis congenita (DC) is characterized by ectodermal dysplasia and hematopoietic failure. The classic triad of ectodermal dysplasia consists of abnormal skin pigmentation, dystrophic nails, and leukoplakia of mucous membranes. In addition to the classic triad, there are a number of other somatic findings in DC. The most common of these are epiphora (tearing due to obstructed tear ducts), developmental delay, pulmonary disease, short stature, esophageal webs, dental caries, tooth loss, premature gray hair, and hair loss. Other ocular, dental, skeletal, cutaneous, genitourinary, gastrointestinal, and CNS abnormalities have also been reported.

Dental Evaluation and Care

Supervision of oral health care is mandatory for patients who receive chemotherapy or radiotherapy to the neck and particularly if they receive both. All patients must undergo dental evaluation and prophylactic treatment and must receive instructions in home care of the teeth, including the use of fluoride prophylactically. Wisdom teeth, including those that are unerupted, and irreparable carious teeth must be removed. Patients must be followed closely during the second dentition to ensure prompt treatment of oral infections and other complications that can occur during the tooth-shedding process. Dental surveillance must continue after the patient is off therapy.

HoYAGErYAGNdYLF Mech drill

Recently, a novel approach to laser caries therapy has been made by Niemz et al. (1993b) and Pioch et al. (1994) when using picosecond pulses from a Nd YLF laser system. Although, at the early stage of experiments, uncertainty predominated concerning potential shock wave effects, it has meanwhile been verified by five independent tests that mechanical impacts are negligible. These consist of scanning electron microscopy, dye penetration tests, hardness tests, histology, and polarized microscopy. Latest results have been published by Niemz (1995b). Scanning Electron Microscopy. In Figs. 4.31a-b, two SEM are shown demonstrating the ability of a picosecond Nd YLF laser to produce extremely precise tetragonal cavities in teeth. The cavities are located in healthy and carious enamel, respectively. Both of them have lateral dimensions of 1 x 1 mm2 and a depth of approximately 400 im. They were created by distributing 1 mJ laser pulses onto 40 lines over the tooth surface with 400 lasered...

Twentyfourhour pH Monitoring

Reflux is more complex than its use for acid reflux diagnosis because of the interaction between mucous and acid secretions, ingested food, saliva, and duodenal, pancreatic, and biliary secretions.42 The score proposed by Fuchs et al.43 allows the quantification of duo-denogastric reflux and gastric acid secretion and could be helpful in the assessment of DGER and gastric emptying disorders. The scoring had a sensitivity of 90 and a specificity of 100 . Alkaline reflux is confirmed by measurement of the time during which the esophageal pH is > 7, but several considerations must be taken into account. Electrodes made of glass instead of antimony should be used, and extreme caution is exerted with the calibration method. The patient's diet should be restricted to food at a pH < 7, the patient should be examined for dental caries that can raise the salivary pH, and strictures should be dilated to prevent

Management Of Chronic Pain

Adequate management of patients with chronic pain requires much time and effort, without which optimal results will be difficult to achieve, and iatrogenic problems may well be produced. In Australia, excellent teaching programmes for doctors, dentists and psychologists in hypnosis, are run by the Australian Society of Hypnosis in the various States (see also Fields, 1975 Working Party on Management of Severe Pain, 1988). The proper use of these approaches, combined with appropriate psychotropic medication, psychological counselling, and with prompt referral of chronic pain patients when indicated to multidisciplinary pain centres (Rose & Fitzgerald, 1987 Rose, 1990) will ensure an improved approach to this difficult area both for the patient and for the busy practitioner.

Visiting The Dentist Is Entrancing

And practicing self-hypnosis is an incredibly rewarding personal growth tool. Beyond that, associating with practitioners from other medical disciplines can be extremely educational and enlightening. In our community, the component section of the American Society of Clinical Hypnosis meets bimonthly to discuss advances in and case studies of clinical hypnosis. Besides the formal meetings, this author meets with three other colleagues (a general surgeon, an oral surgeon and a psychiatrist) on a monthly basis to conduct small group practice of hypnotic techniques. We take turns at being the 'operator' and 'subject', videotape the session and review our individual experience. This group has been conducting these sessions since 1993 and the fact that we still meet regularly is testimony to the value of exploring via hypnosis. The second level is achieved by creating a hypnotically calm dental environment in which direct and indirect, verbal and nonverbal, messages are presented to enhance...

Dental Fears And Phobias

Fear of dentists is commonly listed in the top five commonly held fears and is among the ten most frequent intense fears. Ther are few people who do not experience at least some anxiety and fear associated with dental care. According to Lautch (1971) 'a fear of dental treatment is indeed so common that it can almost be considered normal unless of such a degree to interfere with much needed dental treatment'. It has been estimated that 89 of individuals experience pretreatment anxiety when visiting the dentist (Scott & Humphreys, 1987).

Other Human Uses for Plants

Food production is not the only way whereby plants contribute to human welfare. Coal, oil, and gasoline all, either directly or indirectly, trace their beginnings to plants of long ago. Thus, much of our machinery actually runs on plant products. This book is a product of plants, as are spices, tea, stimulants, sedatives, pain killers, oils, waxes, gums, alcohol, linen, brooms, and Christmas trees. Plants have been used at varying times and in varying cultures to create visions, depose demons, incur blessings, improve fertility, cast spells, cure toothache, and ensure falling in love.

Analysis of Plasma Parameters

Shg Spectral Width Fundamental

One example for the analysis of laser-induced plasmas is the simultaneous caries diagnosis and therapy developed by Niemz (1994a) which is based on the detection of tooth demineralization and is enabled by the evaluation of plasma spectra. A typical setup for such an experiment is shown in Fig. 3.50. Optical breakdown is induced on the tooth surface by a picosecond Nd YLF laser. Then, the plasma is imaged on the entrance pupil of a spectrometer and analyzed. Finally, the data are fed into a computer and processed. Two typical plasma spectra are shown in Figs. 3.51a-b, one of which was obtained from healthy tooth substance, the other from carious substance. Calcium in neutral and singly ionized states and the major doublet of neutral sodium is found in the spectra according to emission wavelengths listed by Weast (1981). They are the minerals occurring most in dental hydroxyapatite with the chemical formula Ca10(PO4)g(OH)2. Phosphorus is also expected, but neither of its strongest...

FDA surveillance systems

Manufacturers and importers are required to submit reports of device-related deaths, serious injuries, and malfunctions. Since enactment of the Safe Medical Device Act (SMDA) in 1990 9 and Medical Device Amendments of 1992 10 , the mandatory universal reporting of adverse events by device user facilities was initiated. Facilities that use medical devices subject to mandatory reporting include hospitals, nursing homes, outpatient diagnostic and treatment facilities, ambulatory surgery centers, ambulance services, and home healthcare service providers. Private offices of physicians, dentists, or other healthcare professionals are exempt from the FDA's mandatory reporting requirements, but practitioners can report problems voluntarily to the FDA. The database currently houses over 1.8 million reports. Approximately 95 of these reports are from industry, and the remaining 5 from healthcare facilities and providers. The number of reports submitted has continued to increase, with...

Clinical Manifestations 21 Orofacial Infections

Dental Caries Both coronal and root caries are common in the elderly population. Coronal caries are more likely to present as recurrent lesions around existing restorations, which are more difficult to detect clinically than new carious lesions. The earliest findings are the presence of pits and fissures on the affected tooth surface that gradually becomes stained due to demineralization of enamel and dentine. Further destruction eventually leads to collapse of the overlying enamel. Because there are no cells or vascular elements in enamel or dentine except for the secondary odontoblasts lying on the pulpal surface, the diseased area is incapable of healing and replacement. The typical clinical presentation is a soft to rubbery textured and discolored defect on the tooth surface. Rapidly progressive caries tend to be soft and can be painful due to involvement of the pulp. Most coronal caries develop slowly as the infection must spread through highly calcified enamel and...

Epidemiology And Clinical Relevance

Orofacial and odontogenic infections are diverse in etiology and clinical presentation. Elderly patients are particularly at risk because of poor oral health and relatively high prevalence of dental caries and periodontal disease. Such infections in the elderly may be localized and indolent, or invasive and life-threatening. Patients with systemic underlying diseases such as diabetes mellitus are also prone to more serious infections. The increasing need for valvular and joint replacements in the elderly also exposes this population to a greater risk for serious complications such as infective endocarditis or prosthetic infections from hematogenous seeding of odontogenic infections (1). 1.1. Prevalence of Dental Caries and Periodontal Disease in the Elderly A survey among adults and senior citizens in the United States revealed that the fraction of individuals aged 65 yr or older who retained some or all of their natural teeth had risen from 40 in 1957 to 60 in 1986 and 72 in 1991...

Tenant Improvement Allowances

At the upper end in terms of construction cost would be radiology suites, oral surgery, ambulatory surgical centers, and many dental suites. All of these contain a great deal of plumbing, electrical, and special construction details that make them extremely expensive to construct. For this reason, physicians and dentists are highly desirable tenants. They invest so much in tenant improvements that they move infrequently. Commercial office tenants often move every few years, whereas it is not unusual for a physician to occupy a space for 10 to 15 years.

Antibacterial activity

The occurrence of LF in saliva has initiated many studies on antimicrobial activity against oral streptococci and contr ol of caries. Apo-LF could cause a potent in vitro growth-inhibition of Streptococcus mutans and this effect could be reversed by iron (Visca et al., 1989). Furthermore, LF seems to reduce the adsorption of S.mutans cells to hydroxyapatite. This adherence-inhibiting effect of apo-LF together with bacteriostasis activity towards S. mutans suggests a possible patho-biological significance of caries control in the oral cavity in vivo. However, apo-bLF seems to elicit a low degree antimicrobial effect on mastitis-associated streptococci in bovine mammary secretions (Todhunter et al., 1985).

Receptor Cells and Transduction

The rates and degrees of receptor adaptation vary among different types of receptors and the specific types of information they detect. Some receptors adapt very quickly to an applied stimulus after a short period of steadily applied stimulation the receptor potential disappears. Such receptors are said to be phasic receptors. For example, if one carefully deflects a hair on the back of one's arm with a pencil point and then holds it steadily in the deflected position, the sensation generated by the deflection quickly disappears. Other receptors show very little adaptation over time such receptors are said to be tonic receptors. Many sorts of pain receptors are tonic, as anyone who has experienced a toothache may attest. Phasic and tonic receptors represent the extreme ends of a continuum. Most receptors can be said to be phasic-tonic receptors, which exhibit a greater or lesser degree of adaptation to continuous stimulation. Phasic and tonic receptors send different types of...

Do You Really Want To Start Smoking

According to the National Cancer Institute, the realization that a dentist cares enough about a patient's health to encourage smoking cessation or continued abstinence from smoking can be a major factor in a patient continuing as a non-smoker. About 95 of non-practicing smokers decided not to start again without the help of formal cessation programs. In addition to having high motivation and good self-management skills, successful former smokers usually receive help and encouragement from family, friends, physicians and dentists. In fact, clinical studies show that patients whose doctors deliver a brief stop-smoking message are 2-10 times more likely to create a positive change than are patients who receive no such advice.

Implication Of The Relationship Of Hypnotizability And Dental Phobias

Forgione (1988) has emphasized that direct and indirect hypnotic suggestions have been shown to distort perception, induce sensory changes and modify expectancies in both phobic and normal populations. Implicit in these findings is a caution for dentists that even if they are untrained or unwilling to practise hypnosis or hypnotic-like techniques, they should be aware that a significant portion of the population is highly responsive to suggestion. Attention should therefore be given not to deliver suggestions to patients that may be counter-productive to treatment.

Example natural rubber and latex allergy

A better measure of the burden of latex allergy on healthcare workers is the incidence (rate of new onset) of latex sensitization onset. Data from the Finnish Register of Occupational Diseases showed that the reported incidence rates of latex contact urticaria were 0.2 10 000 per year for the overall working population, 2.2 10 000 per year for working nurses, 3.9 10 000 per year for working physicians, 6.0 10 000 per year for working dentists, and 11.8 10 000 per year for working dental assistants 70 . A study of 122 apprentices in dental hygiene technology throughout their training showed much higher incidence rates of self-reported measures 249 10 000 per year for skin

Historic Review

Since the first report on laser radiation by Maiman (1960), many potential fields for its application have been investigated. Among these, medical laser surgery certainly belongs to the most significant advances of our present century. Actually, various kinds of lasers have already become irreplaceable tools of modern medicine. Although clinical applications were first limited to ophthalmology - the most spectacular and today well-established laser surgery being argon ion laser coagulations in the case of retinal detachment - the fields of medical laser treatment have meanwhile considerably widened. Due to the variety of existing laser systems, the diversity of their physical parameters, and last but not least the enthusiasm of several research groups almost every branch of surgical medicine has been involved. This should not be interpreted as criticism, although much damage has been done in some cases - especially in the field of biostimulation - when researchers have lost...

The New Consumerism

One would expect a consumer-driven market to spawn competition among healthcare providers who, in the context of this book, are physicians and dentists, not hospitals. Dentists have historically been savvy about marketing and sensitive to consumer issues and there was a time when physicians had more impetus to attend to such concerns. Today, however, reimbursement for medical care has been impacted so dramatically by managed care and HCFA (Health Care Financing Administration) that just keeping the door open and the lights on can be a challenge. And, to be sure, there are large groups of patients who do not have the luxury of shopping for healthcare services they may be uninsured and happy to receive any care at all. That's the reality. Despite this, the issues raised in this chapter are important and should be considered when remodeling or planning new offices.

Study of Dinosaurs

As the fossil is uncovered, it is encased in a block of plaster of paris. (A more modern method uses polyurethane foam instead of plaster.) After the entire surface is covered, the fossil is rolled over, and another layer of plaster is added. After the fossil has been transported to the museum, the plaster is removed. The development stage involves the removal of the rock around the bones. The oldest way is by hand, using tools such as hammers and chisels a more modern technique uses electrically powered drills similar to dentists' drills. Sandblasting and chemicals may also be employed. After the fossil is cleaned, it is ready for mounting. The bones are fastened to a steel framework that makes the skeleton appear to stand by itself.

Therapy

Dental Caries and Periodontitis With the improvement of dental restorative materials such as bonding and fluoride-releasing agents, dental caries in older adults can be readily treated by restorative and prosthodontic treatment programs. Acute necrotizing ulcerative gingivitis should be treated with systemic antimicrobials such as metronidazole or penicillin. Certain types of severe periodontitis are amenable to systemic antimicrobials in conjunction with mechanical debridement (scaling and root planing) (20). Double-blind clinical studies of advanced periodontitis in which systemic metronidazole (500 mg three times day orally) or doxycycline (200 mg two times d orally) for 1 or 2 wk used in conjunction with rigorous mechanical debridement was found to reduce the need for radical surgery by 80 compared with debridement plus placebo control. Oral antimicrobial rinses with

Otolaryngology

The consultation room is large (12X14 feet) since patients are often brought into this room to discuss fees for surgery or to discuss the feasibility of a surgical procedure. The X-ray room can be as small as 8X12 feet, depending on the physician's equipment, since films are limited to the head and neck. The reader is referred to Chapter 3 for space-planning details of an X-ray room, control area, darkroom, and lead shielding. The darkroom can be small, since the physician will probably have a tabletop model automatic film processor similar to the kind used by dentists. The designer must obtain the specs on utility requirements from the manufacturer of the unit.

Plastic Surgery

A plastic surgeon with a cosmetically oriented practice needs to market his or her skills and successes. Dentists specializing in cosmetic or aesthetic dentistry are in somewhat the same situation in terms of being interviewed by prospective patients and having to sell the case. Often, people self-refer, based on a successful outcome of a friend or relative, but the quest for an idealized self-image and the desire to restore one's youthful appearance cause many women (83 percent of plastic surgery patients are women) to interview a number of plastic surgeons.

Symptoms

Acute sinusitis causes pain over the affected sinus, usually the cheek, or on one side of the forehead, a blocked nose and or a discharge, feeling unwell, and a temperature. Facial pain alone without any nasal symptoms is rarely due to sinus disease and is often caused by other types of pain such as midfacial segment pain, tension-type headaches, migraine, dental pain, or trigeminal neuralgia.

Miriam Bollerhoff

This reference on injectable dermal fillers is the first comprehensive manual for the practitioner. It is a perfect symbiosis of pragmatism, experience, and wisdom of two well-known scientists and practitioners from both continents Europe and South America. Today, information on aesthetic surgery is not limited to an exclusive group of injectors any more, but finds a broad, multi-disciplinary interest among many medical specialties. Increasingly, many non-traditional specialties such as gynecologists and dentists offer wrinkle treatment, whether in combination with anti-aging medicine or rejuvenation of the frontal teeth.

Feverfew

Feverfew is a traditional herbal remedy for the relief of arthritis, migraine, toothache, and menstrual difficulties. The plant is a perennial, strongly aromatic herb of the Compositae Asteraceae family, and has been classified variously as Tanacetum parthenium, Chrysanthemum parthenium, Leucanthemum parthenium, or Pyrethrum parthenium, the former name being currently favoured. Studies have confirmed that feverfew is an effective prophylactic treatment in about 70 of migraine sufferers. It reduces the frequency of attacks, the vomiting associated with attacks, and the severity of attacks. The herb has been shown to inhibit blood platelet aggregation, the release of 5-hydroxytryptamine (serotonin) from platelets, the release of histamine from mast cells, and the production of prostaglandins, thromboxanes and leukotrienes. Of a range of sesquiterpene lactones of the germacrane and guianane groups characterized in the leaf material, the principal constituent and major active component is...

Sinusitis

Scan Sinus Abnormality

Acute sinusitis is usually preceded by a viral infection of the upper respiratory tract an estimated 0.5 of common colds evolve into acute sinusitis. No single clinical finding is predictive of acute sinusitis. Three symptoms (maxillary toothache, poor response to decongestants, and history of colored nasal discharge) and two signs (purulent nasal secretion and abnormal transillumination) are the best clinical predictors of acute sinusitis. Sinusitis should be considered when purulent nasal or pharyngeal discharge and cough persist for over a week following a cold. The elderly may complain of headache, facial pain or tightness over the involved sinus, nasal obstruction, nasal quality of voice, and a fever (34). Nasal examination may reveal mucosal hyperemia and mucopurulent discharge. Purulent secretion from the middle meatus is highly predictive of maxillary sinusitis. Direct inspection of the posterior pharynx or use of a pharyngeal mirror may reveal posteriorly draining purulent...

Acupuncture needles

Ancient Japan And Medicine

A recent review on the effectiveness of acupuncture concluded that, despite the difficulties and methodological constraints in conducting high-quality acupuncture clinical trials, a general international agreement has emerged that acupuncture appears to be effective for postoperative dental pain, postoperative nausea and vomiting, and chemotherapy-related nausea and vomiting 11 . For numerous other conditions, the evidence is considered promising, but rigorous research is still needed to add to the body of evidence. For conditions such as asthma, drug addiction, and certain pain conditions, the evidence is considered inconclusive and difficult to interpret. The review also concludes that acupuncture is a relatively safe procedure, although it is not free from serious adverse events.

Site and radiation

Angina pain is characteristically cenlra) and retrosternal. The pain may radiale to either arm. hand or wrist, to die throat or jaw (in which case it may be described as toothache) to the back or the epigastrium. Occasionally pain is experienced in these sites and not in the ehest.

Acute Sinusitis

Acute sinusitis tends to start with a URI that leads to sinus ostial obstruction. The signs and symptoms that increase the likelihood that the patient has acute sinusitis are a double sickening phenomenon whereby the patient seems to improve following the URI and then deteriorates, maxillary toothache, purulent nasal discharge, poor response to decongestants, and a history of discolored nasal discharge (37,38). Other authors have stressed that the symptoms need to persist longer than 1 wk to distinguish sinusitis from a URI (39). It should be pointed out that the commonly used sign of facial pain or swelling has low sensitivity for acute sinusitis (38).

Lasers in Dentistry

Cross Section Tooth Bridge

Although dentistry was the second medical discipline where lasers were applied, it basically remained a field of research. Especially in caries therapy - the most frequent dental surgery - conventional mechanical drills are still superior compared to most types of lasers, particularly CW or long-pulse lasers. Only laser systems capable of providing ultrashort pulses might be an alternative to mechanical drills as was recently shown by Niemz et al. (1993b) and Pioch et al. (1994). However, many clinical studies and extensive engineering effort still remain to be done in order to achieve satisfactory results. We should keep in mind that mechanical drills have improved over several decades until the present stage was reached, and that the development of suitable application units for laser radiation also takes time. Other topics of interest in dentistry include laser treatment of soft tissue as well as laser-welding of dental bridges and dentures. In some of these areas, research has...

Epidemiology

The picture is quite different in the developed world, where the carrier rate is generally less than 1 except in ethnic minorities (e.g., Asian immigrants) and in injecting drug users. Perinatal spread is correspondingly less common, and sexual (including homosexual) transmission among adolescents and adults is a significant risk. Percutaneous transmission by iatrogenic invasive procedures represents the most common identifiable mode of spread, with injecting drug users constituting the largest cohort of carriers. Posttransfusion hepatitis B and infection of hemophiliacs by contaminated factor VIII have now almost disappeared as a result of routine screening of blood and organ donors, but hepatitis B can represent a major occupational risk for laboratory workers who are vulnerable to accidental infection by blood spill or needle-stick injury. Less than 1 xl of blood contaminating a syringe or needle can readily transmit hepatitis B from one individual to another. Professionals...

Teeth And Gum Care

Nutrition plays a vital role in oral health. It not only affects the integrity of oral-cavity development and maintenance but also provides protection from dental plaque and bacteria. The formation of healthy teeth, beginning at about 4 months in utero and continuing until 15 to 16 years of age, requires an adequate dietary intake of calcium, phosphorus, and vitamin D, as per the Recommended Dietary Allowance (RDA). Fluoride plays a key role in ensuring strong enamel composition as well as providing an antibacterial effect to deter the development of dental caries. The fluoride content of drinking water varies from town to town it is therefore recommended that parents contact their local town office for specific fluoride levels before considering fluoride supplementation. Excessive ingestion of fluoride results in mottled enamel (chronic endemic dental fluorosis). Toothpaste should not be used in children less than 2 years of age, and then only in the size of a pea. Fluoride...

Local factors

These relate to oral status and the requirement to prepare a long-term plan for oral health commensurate with the patient's needs and wishes. This will involve an assessment of their oral status, the function of the dentition and the expected benefits of any possible treatment. Maintenance of oral health should take precedence over slavish restoration of the dentition. It is all too easy for both the patient and dentist to focus on the management of a small number of missing teeth, to the long-term detriment of oral health (Fig. 3.5).

Control

Prevention of infection in health care workers and their patients is based on vaccination and universal precautions in the ward, theater, and laboratory founded on the presumption that any patient may be infectious. Barrier techniques include wearing of gloves, gowns, masks, and eyeglasses to prevent exposure to blood in high-risk situations, such as during invasive procedures, avoidance of mouth-pipetting and of eating or smoking while working, meticulous hand washing routines, careful attention to the disposal of blood and body fluids and to cleaning up blood spills with appropriate chemical disinfectants fsuch as 2 glutaratdehyde, 0.5 (5000 ppm available chlorine) sodium hypochlorite, or 1-5 formalin , special precautions in disposal of used needles, the use of disposable equipment wherever possible, and appropriate procedures for the sterilization of reusable equipment. These approaches to aseptic technique and sterilization of equipment should apply equally to dentists,...

Functional Roles

ATP is cosecreted with other transmitters from the terminals of nerves that synapse onto various types of smooth muscle, including those of the vas deferens, blood vessels and gut. It mediates the fast component of the excitatory postsynaptic potential in these tissues. ATP was first shown to be a transmitter in the CNS by Edwards and colleagues (1992), but effects of ATP on many other types of neurone, including those of the hippocampus, hypothalamus and dorsal root ganglia, have also been found. The pharmacology of these responses is consistent with the involvement of P2X receptors, although the subunit(s) that mediates these responses has in most cases not been identified. ATP also stimulates trigeminal nociceptive (pain-sensitive) neurones and plays a key role in the sensation of tooth pain, probably by activation of P2X3 and heteromeric P2X2 P2X3 receptors (Cook et al., 1997).
