|---|---|---|---|
| 설명 | 치아의 조직이 세균에 의해 용해내지 파괴되어 점차 통증을 나타내다가 치아를 잃게 되는 하나의 세균성 병이라고 볼 수 있다. 우리나라에서는 영구치의 충치 이환율이 약 80%로, 한 사람이 2~3개의 충치를 갖고 있는 셈이며, 구강 보건상태는 도시, 농촌지역, 해안지역 순으로 좋다. 원인은 치태(dental plaque)로서, 이것은 점액이나 탈락한 잇몸의 세포들, 그리고 세균 등으로 이루어져 있으며, 점착성이 강하여 치아 표면에 잘 부착되어 양치질이나 칫솔질로는 쉽게 제거되지 않는다. 치태에는 그물모양의 구조내에 막대균과 알균이 섞여 있는데, 특히 내산성 사슬알균과 젖산균이 많다. 현재 가장 유력한 충치의 원인균으로 밝혀지고 있는 이 사슬알균은 설탕을 합성하는 능력을 가지고 있으며, 덱스트란(dextran)을 형성한다고 생각되는데, 이 덱스트란은 물에 녹지 않으며 끈적거리는 점착성이 있어 치태가 치아표면에 잘 붙어 있게 한다. 이 사슬알균은 설탕으로부터 유기산과 치태를 형성한다. 치태 중에는 사슬알균이 생산하는 산이 정체되어 있기 때문에, 이 산에 의해 치아 표면의 단단한 석회질을 녹인다. 대부분이 인산칼슘으로 구성되어 있는 치아의 표면은 산에 의해 칼슘이 분해되어 치아 표면이 거칠어지면서 충치가 진행된다. 이와 같이 세균과 이 세균이 생산하는 화학적 물질에 의해서 충치가 생긴다는 가설을 세균-화학설이라고 한다. 충치의 발생원인에는 이 세균-화학설 이외에도 미생물이 치아표면의 유기질 부위에 먼저 부착되어 산을 만들어 파괴시킨다는 단백용해설도 있으며, 또한 산에 의하지 않는 치아의 파괴, 음식물이 원인이 된다고 주장하는 학설도 있다. 설탕은 충치를 가장 잘 유발시키는 물질로, 섭취 빈도에 따라 충치가 증가한다는 것이 증명되고 있다. 비타민은 충치 요인에 그리 중요하지 않은 것으로 보이며 음식물 내에 존재하는 칼슘과 인 또한 중요하지 않다고 한다. 유전적 소인은 중요한 역할을 하리라 생각되지만 증명하기가 어렵다. |

| London forces | First postulated by van der Waals in 1873 to explain deviations from ideal gas behaviour seen in real gases; the attractive force's between atoms or molecules other than electrostatic (ionic), covalent (sharing of electrons), or hydrogen bonding (sharing a proton); generally ascribed to dipolar and dispersion effects, π-electrons, etc.; these relatively nondescript force's contribute to the mutual attraction of organic molecules. Synonym: London forces. (05 Mar 2000) |

| arab world | A historical and cultural entity dispersed across a wide geographical area under the administrative, intellectual, social, and cultural domination of the arab empire. The arab world, under the impetus of islam, by the eighth century a.d., extended from arabia in the middle east to all of northern africa, southern spain, sardinia, and sicily. Close contact was maintained with greek and jewish culture. While the principal service of the arabs to medicine was the preservation of greek culture, the arabs themselves were the originators of algebra, chemistry, geology, and many of the refinements of civilization.

| greek world | A historical and cultural entity dispersed across a wide geographical area under the influence of greek civilization, culture, and science. The greek empire extended from the greek mainland and the aegean islands from the 16th century b.c., to the indus valley in the 4th century under alexander the great, and to southern italy and sicily. Greek medicine began with homeric and aesculapian medicine and continued unbroken to hippocrates (480-355 b.c.). The classic period of greek medicine was 460-136 b.c. And the graeco-roman period, 156 b.c.-576 a.d. (12 Dec 1998) |
| roman world | A historical and cultural entity dispersed across a wide geographical area under the political domination and influence of ancient rome, bringing to the conquered people the roman civilization and culture from 753 b.c. To the beginning of the imperial rule under augustus in 27 b.c. The early city built on seven hills grew to conquer sicily, sardinia, carthage, gaul, spain, britain, greece, asia minor, etc., and extended ultimately from mesopotamia to the atlantic. Roman medicine was almost entirely in greek hands, but rome, with its superior water system, remains a model of sanitation and hygiene. (12 Dec 1998) |
| western world | A historical and cultural entity dispersed across the wide geographical area of europe, as opposed to the east, asia, and africa. The term was used by scholars through the late medieval period. Thereafter, with the impact of colonialism and the transmission of cultures, western world was sometimes expanded to include the americas. (dr. James h. Cassedy, nlm history of medicine division) (12 Dec 1998) |

| New World leishmaniasis | A grave disease caused by Leishmania braziliensis braziliensis, endemic in southern Mexico and Central and South America, except for the equatorial region of Chile; the organism does not invade the viscera, and the disease is limited to the skin and mucous membranes, the lesions resembling the sores of cutaneous leishmaniasis caused by L. Mexicana or L. Tropica; the chancrous sores heal after a time, but some months or years later, fungating and eroding forms of ulceration may appear on the tongue and buccal or nasal mucosa; many variants of the disease exist, marked by differences in distribution, vector, epidemiology, and pathology, which suggest that it may in fact be caused by a number of closely related aetiological agents. See: espundia. Synonym: American leishmaniasis, leishmaniasis americana, nasopharyngeal leishmaniasis, New World leishmaniasis. (05 Mar 2000) |
