“…This result is in agreement with some studies reporting similar distributions of MIH in molars from both arches (3,15,16), but contrasted with other studies reporting that mandibular (12,17) or maxillary (4,18,19) molars were affected more frequently. In agreement with the results of other studies (17,19), MIH affected the maxillary incisors more frequently than the mandibular incisors in the present study.…”

“…Dobiveni rezultati slažu se s istraživanjima sa sličnom raspodjelom MIH-a na kutnjacima u oba zubna luka (3,15,16), ali se razlikuju od istraživanja u kojima se tvrdi da su MIH-om češće zahvaćeni mandibularni (12,17) ili maksilarni kutnjaci (4,18,19). U skladu s rezultatima drugih istraživanja (17,19), u ovome MIH pogađa maksilarne kutnjake češće nego mandibularne sjekutiće.…”

“…Presence of hypo-mineralization and caries in the same tooth might affect the proper diagnosis of enamel breakdown whether it is actually due to caries or hypo-mineralization or a combination of both. Similar to other studies (Cho et al, 2008;Kirthiga et al, 2015), in the present study, PFM with caries, post-eruption enamel breakdown or restoration was recorded as MIH if demarcated enamel opacities remained at the borders or on the other surfaces. This might explain the large number of PFMs with post-eruptive enamel break down observed in the present study.…”

Aims. To evaluate the prevalence of and describe molar-incisor hypomineralization (MIH) in a group of female children in Riyadh, Saudi Arabia. Methods. The sample consisted of 8-10-year-old (n=682) female student"s attending female elementary schools and females of the same age attending pediatric dentistry clinics at the College of Dentistry, King Saud University, Riyadh. Subject"s permanent first molars (PFMs) and incisors were examined for demarcated opacities, post-eruptive enamel breakdown, atypical restorations and extraction due to MIH. Results. 277 children were affected by hypomineralization giving a prevalence rate of 40.6%. The mean affected teeth was 6.5±3.18 (3.8 molars and 2.7 incisors) per child. 46.9% had only molars hypo-mineralization (MH), while 53.1% had molars and incisors affected (MIH). Proportional t-test showed no statistically significant difference between the number of affected upper and lower molars, while upper incisors are affected more than lower incisors. Moderate/severe hypo-mineralization predominated in both MIH and MH with MIH children having more moderate/severely affected teeth. MIH prevalence has no association with the age, but ten-year-old have more moderate/severely affected teeth (P=0.041) than eight and nineyear-old children. Conclusion. The observed prevalence of MIH in Riyadh female children was high. Carefully planned short and longterm preventive and therapeutic programs and nationwide larger scale epidemiological studies are needed.

“…Yapılan diğer bir araştırmada, yaşamın ilk 3 yılında gözlenen çocukluk hastalıklarının BAKH ile ilgili olduğu düşünülmektedir. Bu çocukluk hastalıkları arasında üst solunum yolu enfeksiyonları, bronşit, zatür-re, astım, suçiçeği, orta kulak iltihabı, tonsilit, kızamık ve kızamıkçık vardır (5,8,(11)(12)(13)(14)(15)(16)(17)(18). Erken çocukluk döneminde geçirilen sistemik rahatsızlıklar sonucunda ameloblastlara yeterli oksijen sağlanama-dığından dolayı bu rahatsızlıklar BAKH'nin etiyolojik faktörlerinden kabul edilirler (8,18).…”

Yeditepe Üniversitesi Diş Hekimliği Fakültesi, İstanbul, Türkiye Molar incisor hypomineralization (MIH) is defined as the hypomineralization of one or more first permanent molars with or without the involvement of the maxillary and mandibular permanent incisors. Although the etiology of MIH remains unclear, several etiological factors, such as the genetic and environmental factors and systemic disturbance during pre-, peri-, and postnatal period, can cause enamel defects and their occurrence. The prevalence of MIH is reported to be between 2.4% and 25% in different communities. Teeth with MIH are extremely hypersensitive, prone to rapid caries development, and can be difficult to manage in young patients, and thus, dentists may have difficulties during diagnosis, treatment planning, and managing children with MIH during treatment. Early diagnosis is essential because rapid breakdown of tooth structure may occur, resulting in acute symptoms and complicated treatment. This study aimed to review the diagnosis and etiological factors involved in the occurrence of MIH and to evaluate treatment approaches in the management of MIH. Keywords: Molar incisor hypomineralization, children, incisor, molar GİRİŞ Tanımı ve Oluşum MekanizmasıBir veya birkaç sürekli birinci büyük azı dişi ile birlikte sürekli keser dişlerinde etkilenebildiği, etiyolojisi tam olarak bilinmeyen, amelogenezisin olgunlaşma safhasında gözlenen, sistemik kaynaklı klinik hipomineralizasyona büyük azı keser hipomineralizasyonu (BAKH) denir (1). Son yıllarda yapılan çalışmalarda BAKH'nin sadece daimi dişleri etkilediği düşünülürken, Elfrink ve ark. (2) süt dişlerinde de BAKH görüldüğünü bildirmişler ve süt dişlerinin etkilendiği bu hipomineralizasyonu "süt azı keser hipomineralizasyonu" olarak tanımlamışlardır (2, 3). Doku anomalileri dişlerin organik matriks yapımı ve mineralizasyonunun histogenez döneminde karşılaştığı etkenler sonucunda meydana gelmektedir. Amelogenezis 3 ana evreden oluşur (4). Salgılama Evresi: Ameloblastlar mine matriks proteini üretirler. Mine oluşumu öncelikle tüberkül tepelerinden başlar ve servikale doğru ilerler. Hidroksiapatit kristalleri uzayarak büyümeye başlar ve bu sayede mine tabakası kalınlaşır. Bu evrede minenin %20'si mineralden oluşurken geri kalan kısmı ise su ve mine matriks proteininden oluşmaktadır (4).Geçiş Evresi: Mine matriks salgılanması sonucunda mine tam kalınlığına ulaşır. Ameloblastlar olgunlaşma evresindeki ameloblastlara dönüşür (4).Olgunlaşma Evresi: Olgun ameloblastlar mineralizasyonu düzenlerler ve mine tabakası sertleşir, kalınlaşır, kristaller büyür, mineralizasyonun %95'i tamamlanmış olur. Doğumda sekonder mineralizasyon tüberkül tepelerinden itibaren başlar ve mineralizasyon doğumdan sonraki 1 yıl boyunca devam eder (4).
