Abstract

Purpose: The primary aim of this study was twofold: first, to assess the prevalence of molar incisor hypomineralization (MIH) within a cohort of Egyptian children and, second, to investigate the potential correlation between MIH and various factors, including age, sex, birth complications, and endogamous marriage.

Patients and Methods: This cross-sectional investigation took place in Egypt's Delta region, with approximately 3000 children aged between eight and twelve years being recruited for participation. The European Academy of Pediatric Dentistry (EAPD; 2003) criteria served as the diagnostic tool for identifying MIH cases. Upon detection of clinical signs or symptoms indicative of MIH, parents were queried regarding any potential birth complications or endogamous marriages. Lesion severity levels were diagnosed using Mathu-Muju and Wright criteria.

Results: The prevalence rate for MIH was found to be 7.2%. Molars exhibited higher susceptibility rates than incisors (64.8% vs 35.2%), with approximately 37% of participants displaying severe scores, followed by mild (33.8%) and moderate (29.2%). Male subjects had significantly more occurrences than females, with positive correlations identified between MIH incidence rates alongside each gender category as well as both birth complications and endogamous marriages.

Conclusion: Children born from complicated pregnancies or whose parents are related should receive frequent check-ups from pediatric dentists during their first permanent molar eruption period. so that early detection of MIH can be facilitated allowing timely intervention.

Mısır’lı çocuklarda büyük azı-kesici diş hipomineralizasyonunun prevalansı ve belirleyicileri: kesitsel bir çalışma

Abstract

Amaç: Bu çalışmanın birincil amacı iki yönlüydü: birincisi, bir grup Mısırlı çocuk arasında büyük azı-kesici diş hipomineralizasyonu (MIH) prevalansını değerlendirmek ve ikincisi, MIH ile yaş, cinsiyet, doğum komplikasyonları ve akraba evliliği gibi çeşitli faktörler arasındaki olası korelasyonu araştırmak.

Hastalar ve Yöntemler: Bu kesitsel araştırma, Mısır’ın Delta bölgesinde gerçekleştirildi ve sekiz ile on iki yaşları arasında yaklaşık 3000 çocuk katılım için seçildi. MIH vakalarını belirlemek için Avrupa Pediatrik Diş Hekimliği Akademisi (EAPD; 2003) kriterleri tanı aracı olarak kullanıldı. MIH’ı gösteren klinik belirti veya semptomlar tespit edildiğinde, ebeveynlere olası doğum komplikasyonları veya akraba evlilikleri hakkında sorular soruldu. Lezyon şiddet seviyeleri Mathu-Muju ve Wright kriterlerine göre teşhis edildi.

Sonuçlar: MIH prevalans oranı %7,2 olarak bulundu. Büyük azı dişlerinde kesici dişlere göre daha yüksek duyarlılık oranları görüldü (%64,8’e karşı %35,2), katılımcıların yaklaşık %37’si ciddi skorlar gösterirken, bunu hafif (%33,8) ve orta (%29,2) dereceler izledi. Erkek denekler, kadınlara göre anlamlı derecede daha fazla vaka gösterdi ve MIH insidans oranları ile her iki cinsiyet kategorisinin yanı sıra hem doğum komplikasyonları hem de akraba evlilikleri arasında pozitif korelasyonlar tespit edildi.

Sonuç: Komplike gebeliklerden doğan veya ebeveynleri akraba olan çocuklar, ilk daimi büyük azı dişlerinin sürme döneminde pediatrik diş hekimleri tarafından sık sık kontrol edilmelidir. Bu şekilde MIH’ın erken tespiti sağlanarak zamanında müdahale yapılabilir.
