DOI: Abstract PDF. Dental fluorosis is a chronic fluoride —induced condition in which an excess of fluoride is incorporated in the developing tooth enamel and disrupt the enamel formation of the tooth. Prevalence of dental fluorosis due to high levels of fluoride in drinking water is an endemic global problem.

The draft document, produced by a working group of experts convened to consider protection from fluoride and its control, was issued for extensive review and consultation. The resultant book, which incorporates the comments received, was further peer review by experts in developed and developing countries.

Dental caries is still one of the major public health problems. The most effective way of caries prevention is the use of fluoride. The aim of our research was to review the literature about fluoride toxicity and to inform physicians, dentists and public health specialists whether fluoride use is expedient and safe. Data we used in our review were systematically searched and collected from web pages and documents published from different international institutions. Fluoride occurs naturally in our environment but we consume it in small amounts.

Fortunately, chemistry has not changed much since I learned the material as an undergraduate. The source material is accurate and the examples used to emphasize these are current. The book is well written and concise.

Volcanic regions have always attracted many people worldwide because of the high fertility of their soils. However, human proximity to volcanoes can lead to several health problems as consequence of the chronic exposure to the materials released from the volcanic activity. An element often found in elevated concentrations in volcanic regions is fluorine. Although fluoride is recognized to have a beneficial effect on the rate of occurrence of dental caries when ingested in small amounts, its excessive intake results in a widespread but preventable pathological disease called fluorosis. In some volcanic regions, where exposure to elevated amounts of fluoride is persistent, biomonitoring programs are fundamental to assess the main sources of exposure and to evaluate the effects of the exposure in resident populations.

Между деревьев в левой части кадра что-то сверкнуло, и в то же мгновение Танкадо схватился за грудь и потерял равновесие. Камера, подрагивая, словно наехала на него, и кадр не сразу оказался в фокусе. А Смит тем временем безучастно продолжал свои комментарии: - Как вы видите, у Танкадо случился мгновенный сердечный приступ. Сьюзан стало дурно оттого, что она увидела.

По крайней мере Мидж не станет болтать. У нее есть и свои слабости. Она ведь и сама кое-что себе позволяла: время от времени они массировали друг другу спину.

Смерть остановит боль. Она будет опять рядом с Дэвидом. Шифровалка начала вибрировать, словно из ее глубин на поверхность рвалось сердитое морское чудовище. Ей слышался голос Дэвида: Беги, Сьюзан, беги. Стратмор приближался к ней, его лицо казалось далеким воспоминанием. Холодные серые глаза смотрели безжизненно. Живший в ее сознании герой умер, превратился в убийцу.

 - Ясно, что это будет число-монстр. Сзади послышался возглас: - Двухминутное предупреждение. Джабба в отчаянии бросил взгляд на ВР. Последний щит начал рушиться. Техники сновали по комнате.

 - Мисс Флетчер, вы проделали уже немалую часть пути. Постарайтесь пройти по нему до конца. Сьюзан вздохнула: - Программа принимает ключ только в цифровой форме. Мне кажется, что тут содержится некий намек на то, что это за цифра. В тексте названы Хиросима и Нагасаки, города, разрушенные атомными бомбами.

Фонтейн был гигантом из гигантов, но Стратмора это как будто не касалось. Он отстаивал перед директором свои идеи со спокойствием невозмутимого боксера-профессионала. Даже президент Соединенных Штатов не решался бросать вызов Фонтейну, что не раз позволял себе Стратмор. Для этого нужен был политический иммунитет - или, как в случае Стратмора, политическая индифферентность. Сьюзан поднялась на верхнюю ступеньку лестницы.
