Epidemiologic study of idiopathic enamel hypomineralization in permanent teeth of Swedish children

Abstract

In the late seventies an increasing number of children showing extensive and severe idiopathic hypomineralization of the enamel of incisors and permanent first molars was reported within the Public Dental Services in Sweden. An epidemiologic study was initiated to analyze the prevalence, extension and severity in Swedish children born in 1970 and in the years before and after. 2252 children born in 1966-74 were examined according to well defined criteria on enamel hypomineralization. It was found that 15.4% of the children born in 1970 showed such changes. The corresponding figures for children born in 1966, 1969, 1971, 1972 and 1974 were 6.3, 7.3, 7.1, 5.2 and 4.4, respectively.

Possible Medical Aetiological Factors and Characteristics of Molar Incisor Hypomineralisation in a Group of Turkish Children

“…Autori su se za to stanje koristili sljedećim nazivima: hipomneralizirani trajni prvi kutnjaci, idiopatska caklinska hipomineralizacija, nefluoridna hipomineralizacija i sirasti kutnjaci (1,2,3). Caklinska hipoplazija (EH) može uključi-vati kvantitativne defekte u caklini zbog poremećaja ameloblasta tijekom stvaranja matriksa (4,5,6) i/ili kvalitativne defekte potaknute poremećajem u početnoj mineralizaciji i/ili sazrijevanju cakline (4,5).…”

“…Tako su roditeljima postavljena pitanja o prehrani djeteta, navikama četkanja zuba, majčinoj anamnezi (infekcije i bolesti) u trudnoći, porođaju (prijevremeni porođaj, komplikacije pri rođe-nju), alergijama, korištenju antibiotika, vrućicama (≥ 39°C) i infekcijama prije djetetove treće godine, kao što je to u literaturi opisano (1,6,10,12,13).…”

“…Questionnaire items addressed the children's eating and tooth-brushing habits, mothers' medical histories (infections and illnesses) during pregnancy, delivery characteristics (premature birth, birth complications), allergies, antibiotic use, fevers ≥ 39°C, and infections during the children's first 3 years of life, as described in previous studies (1,6,10,12,13). Medical information about children in the control group and their mothers was retrieved in the same way.…”

“…Authors have used various terms to refer to this condition, including 'hypomineralised permanent first molars', 'idiopathic enamel hypomineralisation', 'nonfluoride hypomineralisation', and 'cheese molars' (1,2,3). Enamel hypoplasia (EH) can involve a quantitative defect in the enamel resulting from the disturbance of ameloblasts during matrix formation (4,5,6) and/or a qualitative defect caused by disturbance during initial calcification and/or maturation (4,5).…”

Büyük azı ve kesici diş hipomineralizasyonu: etiyolojisi ve kliniği

“…1,2 İlk çalışmalar, 1970'lerin sonlarında İsveç'te yapılmış ve minenin gelişimi sırasında meydana gelen bazı etkenlerin bu defektin oluşumunda etkili olabileceği öne sürülmüştür. 3 Literatürde, bu gelişimsel mine defektlerini tartışırken olası herhangi bir etiyolojik durumu anlatmayan tek bir isim kullanıl-ması gerektiği belirtilmiştir. Bu nedenle BAKH terimi, bazen kesicilerin de eşlik ettiği dört daimi birinci büyük azının bir veya daha fazlasının sistemik kökenli hipomineralizasyonunu tanımlamak için önerilmiştir.…”
