摘要：Amaç: Prematüre doğan çocukların süt dişlerinde izlenen gelişimsel mine defektlerinin (GMD) görülme sıklığı ve tiplerinin, normal doğum yaşında dünyaya gelmiş çocuklar ile karşılaştırılmasıdır. Gereç ve Yöntem: Araştırmaya 150 çocuk dahil edildi. Çocuklar, prematüre doğan ( n=75, yaş=7.1 ± 2.9 yıl) ve normal doğum yaşında doğmuş çocuklar (kontrol grubu, n=75, yaş=7.6 ± 2.5 yıl) olmak üzere iki gruba ayrıldı. Klinik muayenede her iki grupta GMD olup olmadığı belirlendi. GMD belirlenen dişler, Modifiye GMD İndeksindeki tiplere göre sınıflandırıldı. Veriler Pearson ki-kare, Fisher'in kesin testi ve t-testi kullanılarak istatistiksel olarak analiz edildi. Bulgular: Prematüre grubunda 34/75 (%45.3) çocukta, kontrol grubunda ise 15/75 (%20) çocukta GMD saptandı (p<0.01). Çalışmada toplam 193 dişte GMD tespit edildi. Prematüre grupta GMD görülme sıklığı (n=148, %76.7), kontrol grubundan (n=45, %23.3) daha fazlaydı. En fazla GMD, prematüre grubunda maksiller keser dişlerde, kontrol grubunda ise maksiller molar dişlerde izlendi. Prematüre grubundaki GMD’nin %88.5’i (n=131) mine opasitesi (sınırlı beyaz/krem rengi opasite, sınırlı sarı/kahverengi opasite, diffüz çizgi şeklinde opasite ve diffüz yamalı opasite) ve %11.5’i (n=17) mine hipoplazisi tipindeyken; kontrol grubundaki dişlerin tümünde mine opasitesi (n=45, %100) şeklindeydi. Prematüre grubunda, minede s ınırlı beyaz/krem rengi opasite ve sınırlı sarı/kahverengi opasite bulunan diş sayısı kontrol grubuna göre istatistiksel olarak anlamlı düzeyde fazla bulundu (p<0.01). Sonuç: Çalışmanın sonuçları, prematüre doğan çocukların süt dişlerinde normal doğum yaşında dünyaya gelmiş çocuklardan daha fazla GMD görüldüğünü, bu defektlerin çoğunlukla maksiller kesici dişlerde ve minede sınırlı opasite şeklinde ortaya çıktığını gösterdi. Objective: To compare the prevalence and developmental enamel defect (DED) types in primary teeth in preterm-born with term-born children. Materials and Method: This study included 150 children. The children were divided into two groups as premature (n=75, mean age= 7.1 ± 2.9 year) and term-born (control group, n=75, mean age=7.6 ± 2.5 year). In the clinical examination, DED and the defect type were recorded according to the modified DED index. Data were analyzed using Pearson's Chi-Square, Fisher's exact and t-tests. Results: DED was observed 34/75 (45.3%) in the premature group and 15/75 (20%) in the control group (p<0.01). DED was detected in 193 teeth. The prevalence of DED was higher in the premature group (n=148, 76.7%) than in the control group (n=45, 23.3%). DED was most commonly found in the maxillary incisors of the premature group and the maxillary molars of the control group. The DED types were found to be enamel opacity (demarcated white/cream opacity, demarcated yellow/brown opacity, diffuse opacity as lines, and diffuse patchy opacity) in 88.5% (n=131) teeth and enamel hypoplasia in 11.5% (n=17) teeth of the premature group, and as enamel hypoplasia in all teeth of the control group (n=45, 100%). Significantly more teeth in the premature group than in the control group exhibited demarcated white/cream opacity and demarcated yellow/brown opacity at the enamel (p<0.01). Conclusion: This study showed that premature children had more DED than term-born children, and these defects were mostly observed in the maxillary incisors and observed as demarcated opacities.
