| 설명 | 치아의 한 부분을 이르는 말이다. 치아관을 피복하는 회백색 반투명의 단단한 물질이다. 치아는 크게 치아관(crown)과 치근(root)으로 나눌 수가 있다. 치아관이란 구강내로 돌출하고 있는 치아의 부분이며, 치근이란 치아관 아래에 존재하는 치아의 부분을 말한다. 사기질은 치아관을 둘러싸고 있는 아주 단단한 조직으로 우리가 입안으로 직접 관찰할 수가 있는 흰색을 띠는 것이다. 전신에서 가장 단단한 부분으로 굳기 6~7° 이므로 석영과 거의 비슷하다. 사기질소주라고 하는 3~5μm 굵기의 사상체의 집합으로 한 개의 이에 수백만 개의 작은기둥이 있다. 사기질은 한번 마모되거나 녹아 버리면 다시 신생되지 않는다. 잇몸의 내부에 있는 치근부에서는 상아질 표면이 시멘트질로 덮여 있다. 사기질에는 신경이 없으므로 여기에 생긴 충치에는 치통이 없으나, 상아질까지 침범되었을 때 냉수가 스며들면 이가 시리고 치통이 시작된다. 소량의 플루오르화물을 섭취하면 이가 건강해진다고 하지만 과다하면 사기질을 상하게 한다. |

| 설명 | 장기의 불완전한 발달 때문에 성인의 크기에 도달하지 못한 상태. 그 중증도는 무형성보다 가볍다. 개체의 발달과정에서 어떤 원인에 의해 장기조직의 형성이 불완전하게 되는 것을 말한다. 기관 원기는 존재하지만 발육이 불완전하게 끝난 상태이다. 대다수의 경우 원인은 불확실하지만, 원인으로서 생각되는 것으로는 유전, 감염, 영양장애, 내분비장애, 외상, 방사선 등을 들 수 있다. 장기조직이 정상적으로 형성된 뒤 그 체적이 감소해 가는 위축과는 구별된다. |

| dental enamel hypoplasia | <dentistry> A form of amelogenesis imperfecta characterised by incomplete formation of the dental enamel and transmitted as an x-linked or autosomal dominant trait. It is also associated with vitamin a, c, or d deficiency, infectious disease, prematurity, birth injury, rh incompatibility, trauma, or local infection. Small grooves, pits, and fissures are seen in mild cases, deep horizontal rows of pits in severe cases, or absence of enamel in extreme cases. (12 Dec 1998) |

| enamel hypoplasia | A developmental disturbance of teeth characterised by deficient or defective enamel matrix formation; may be hereditary, as in amelogenesis imperfecta, or acquired, as encountered in dental fluorosis, local infection, childhood fevers, and congenital syphilis. (05 Mar 2000) |
| parathyroids, hypoplasia of the thymusand | Also known as the digeorge syndrome (dgs), this disorder is characterised by (1) low blood calcium levels (hypocalcaemia) due to underdevelopment (hypoplasia) of the parathyroid glands which control calcium; (2) underdevelopment (hypoplasia) of the thymus, an organ behind the breastbone in which lymphocytes mature and multiply; and (3) defects of the heart involving the outflow tracts from the heart. most cases of dgs are due to a microdeletion in chromosome band 22q11.2. A small number of cases have defects in other chromosomes, notably 10p13. Named after the american paediatric endocrinologist angelo digeorge. Another name for dgs is the third and fourth pharyngeal pouch syndrome. (12 Dec 1998) |
| cartilage-hair hypoplasia | An autosomal recessive form of dwarfism characterised by shortness of the extremities without skull defects, and with sparse, brittle hair of light colour. There is a peculiar, not adequately explained severity in the clinical course of varicella and herpes in such patients. (05 Mar 2000) |
| renal hypoplasia | An abnormally small kidney that is morphologically normal but has either a reduced number of nephrons or smaller nephrons. (05 Mar 2000) |
| right ventricular hypoplasia | A congenital or acquired condition in which there is thinning of the right ventricular myocardium. Synonym: right ventricular hypoplasia. (05 Mar 2000) |
| hypoplasia | <embryology> The incomplete development or underdevelopment of an organ or tissue. Origin: Gr. Plasis = formation (18 Nov 1997) |
| hypoplasia of right ventricle | Failure of development of the right ventricle resulting in its having little muscle and much connective tissue instead of the reverse. (05 Mar 2000) |
| hypoplasia of the thymus and parathyroids | Also known as the digeorge syndrome (dgs), this disorder is characterised by (1) low blood calcium levels (hypocalcaemia) due to underdevelopment (hypoplasia) of the parathyroid glands needed to control calcium; (2) underdevelopment (hypoplasia) of the thymus, an organ behind the breastbone in which lymphocytes mature and multiply; and (3) defects of the outflow tracts from the heart. most cases of dgs are due to a microdeletion in chromosome band 22q11.2. A small number of cases have defects in other chromosomes, notably 10p13. Named after the american paediatric endocrinologist angelo digeorge. Another name for dgs is the third and fourth pharyngeal pouch syndrome (since the faulty structures in dgs are embryologically derived from the third and fourth pharyngeal pouches). (12 Dec 1998) |
| optic nerve hypoplasia | Congenitally small optic disk resulting from failure of development of retinal ganglion cells, with a reduced number of axons; visual impairment may be marked. See: de Morsier's syndrome. (05 Mar 2000) |

| thymus and parathyroids, hypoplasia of | See third and fourth pharyngeal pouch syndrome. (12 Dec 1998) |
| focal dermal hypoplasia | A genetic skin disease characterised by hypoplasia of the dermis, herniations of fat, and hand anomalies. It is found exclusively in females and transmitted as an x-linked dominant trait. (12 Dec 1998) |
| reduced enamel epithelium | The several layers of the enamel organ remaining on the enamel surface after formation of enamel is completed. Synonym: reduced enamel epithelium. (05 Mar 2000) |
| mottled enamel | Alterations in enamel structure due to excessive fluoride ingestion during tooth formation; varies in appearance from small white opacities to yellow and black spotting. Nanoid enamel, a condition of abnormal thinness of the enamel. Synonym: dwarfed enamel. Whorled enamel, enamel in which the rods assume a spiral or twisting course. (05 Mar 2000) |
