Trends in dental education 2000: the past, present and future of the profession and the people it serves. A compari- son of the educational costs and incomes of physicians and other professionals. Research involves experimentation and observation, and through this mechanism information is converted to practical application. Research has enabled advances in diagnosis, disease treatment and management and in the prevention of oral diseases and conditions. Through research, the preventive effects of fluoride for dental caries and spe- cific risk factors for periodontal disease were identified. These findings led to improved interventions and a reduction in the oral disease burden. Ongoing and future research concerning the fundamental mechanisms of oral disease will continue to drive change in dental practice. Through epidemiological and behavioral research, the dental profession has made advances in understanding the causes and progression of dental disease. Epidemiological research, through national surveys of oral health such as the National Health and Nutrition Examination Survey, has been invaluable in improving the understanding of the extent, distribution, and determinants of most dental diseases and their relationships to general health. Epidemiological research demonstrates that underserved populations shoulder a disproportionate burden of disease. For example, the death rate from oral cancer for African American males is double that for White males despite only a 20% higher incidence rate of oral cancer among African Americans. This disparity reflects the fact that African Americans have more advanced disease at the time of diagnosis and initiation of treatment. Additional epidemiological research is needed to characterize disease patterns in specific pop- ulation groups, to understand why diagnoses are not made earlier, to develop new strategies for reaching people who are at risk for oral diseases, and to evaluate treatment outcomes. Research has shown that behaviors that are under the direct control of the individual can influence the develop- ment of many dental conditions. Examples include the relationship between sucrose consumption and caries, poor oral hygiene and periodontal diseases, and smoking and oral cancer. More behavioral research is needed to design effective interventions to deter individuals from harmful personal habits and to promote preventive behaviors. The transfer of research-based knowledge and technology to practicing dental professionals has lagged behind the expansion of the knowledge base on the etiology of dental diseases and methods of treatment. Hence, there is a need to evaluate and improve the speed and quality of information and technology trans- ferred from the laboratory and other research settings to the public domain. This chapter discusses the current state of knowledge about nine defined categories of oral diseases and conditions, and identifies research directions for the future with respect to these diseases and conditions. The chapter is not inclusive of all dental diseases; rather, these disorders are intended to illustrate the direc- tions and challenges for dentistry in the future. Progress through research will challenge dentists and students with a need to become familiar with the molecular and genetic basis of oral diseases. This process will help to assure that dentistry continues as a vital and progressive profession. As the relationships between oral and systemic diseases are clarified, issues will arise about which profes- sionals have the responsibility for diagnosing and managing oral disease and who will pay for treatment. An increased understanding of the inter- profession’s recognition of the value of a constantly dependent role of personal lifestyle behaviors, profes- expanding scientific base is clear. Dental research has led to develop- transferred and disseminated effectively, efficiently ments in disease prevention, diagnosis and treat- and in a timely manner to those who will use it.

These agents may be used to produce a desired alkalinization of urine to enhance renal secretion of uric acid and cysteine discount propecia 1 mg on line hair loss cure latisse. Adverse reactions include metabolic acidosis due to reduction in bicarbonate stores purchase propecia 1mg free shipping hair loss in children. Urine alkalinity decreases the solubility of calcium salts and increases the propensity for renal cal- culi formation. Following large doses, carbonic anhydrase inhibitors commonly produce drowsiness and paresthesias. These agents are easily filtered, poorly reabsorbable solutes that alter the diffusion of water relative to sodium by + ‘‘binding’’ water. Even when filtration is reduced, sufficient mannitol usually enters the tubule to promote urine output. Studies have suggested that vasopressin and its analogues are useful to maintain blood pressure in patients with septic shock. These drugs produce serious cardiac-related adverse effects, and they should be used with caution in individuals with coronary ar- tery disease. Xanthine diuretics act by increasing cardiac output and promoting a higher glomerular filtra- tion rate. They are seldom used as diuretics, but diuresis occurs under other clinical applica- tions (e. They are sometimes used in combination with high-ceiling diuretics to counteract alkalosis. Nondiuretic inhibitors influence transport of organic anions, including the endogenous anion uric acid, and cations. Transport takes place in the proximal tubule; organic compounds + enter a cell by Na -facilitated diffusion and are excreted from the cell into the lumen by a specific organic ion transporter. Para-aminohippurate, not used clinically, is a classic compound used to study these phenomena. Paradoxically, because of the balance among uptake into a cell, excretion from the cell, and reabsorption from the lumen, low doses of these agents often decrease excretion, whereas high doses increase excretion. Probenecid was developed to decrease secretion of penicillin (an organic acid) and thus prolong elimination of this antibiotic. Other drugs whose secretion is inhibited by probenecid include indomethacin and methotrexate. This results in a net increase in urate excretion and accounts for the drug’s usefulness in treating gout. The most common adverse effects of probenecid are hypersensitivity reactions and gastric irritation. Allopurinol is metabolized by xanthine oxidase to produce alloxanthine, which has long-lasting inhibitory effects on the enzyme; the net result is decreased production of uric acid.

Thiazide diuretics inhibit active reabsorption of sodium chloride in the early distal convoluted tubule of the nephron by interfering with the Na/Cl cotransporter, resulting in net excretion of sodium and water. Inhibiting reabsorption of sodium chloride in the thick ascending limb of the loop of Henle describes the mechanism of action of loop diuretics. Interfering with potassium secretion refers to mechanism of action of potassium-sparing diuretics. Thiazide diuretics decrease excretion of calcium and thus can be used for idio- pathic hypercalciuria. Loop diuretics stimulate tubular calcium excretion and can thus be used to treat hypercalcemia. Carbonic anhydrase inhibitors, potassium-sparing diuretics, and osmotic diuretics do not have a significant impact on net calcium balance. Hydrochlorothiazide, a thiazide diuretic, can precipitate a gouty attack in pre- disposed individuals. This is because these agents increase serum uric acid as a result of competi- tion for the organic acid carrier. Acetazolamide is a carbonic anhydrase inhibitor; this agent does not have a significant impact on the levels of uric acid.
