CLINICAL AND RADIOLOGICAL EVALUATION OF A PREFORMED COMPOSITE CROWN IN SEVERELY DECAYED PRIMARY MOLARS

Abstract

The aim of this study was to evaluate the clinical and radiographic success and parental acceptance of a preformed composite crown (PTC) for primary molars and compare with that of conventional stainless steel crowns (SSC). A total of 38 children (Girls:12, Boys:26) in five-nine age range, selected from among patients attending the pediatric dentistry clinic. Seventy-sixth crowns were applied in a split-mouth design with a random allocation for mandibular primary 1st and 2nd molars. Assessment of the clinical and radiographic performance of the restorations was performed by two calibrated examiners during 12-month follow-up period and parental satisfaction was determined for both crowns.Total clinical success rates were 100% and 63% for SSCs and PTCs, respectively, at the end of 12-month follow-up, and the difference was statistically significant (p<0.05). Despite the high rates of cementation and endodontic failures, parents were much more satisfied with PTCs (p<0.05). It has been determined that SSCs is more successful than PTCs, but PTCs were preferred by parents due to their aesthetic features.Despite the high rate of aesthetic satisfaction in the PTC group, studies are needed to evaluate the coronal leakage factor in terms of its potential to cause the problems of "falling out of crowns" and "endodontic problems", observed as clinical failure.

AŞIRI MADDE KAYIPLI SÜT AZI DİŞLERİNDE BİR PREFABRİK KOMPOZİT KRONUN BAŞARISININ KLİNİK VE RADYOLOJİK DEĞERLENDİRİLMESİ

Abstract

Bu araştırmada aşırı madde kaybı olan süt azı dişlerinin tedavisinde prefabrik kompozit kuronlar (PK) ile paslanmaz çelik kuronların (PÇK) başarısının klinik ve radyografik olarak karşılaştırılması ve ebeveynlerin memnuniyetinin ölçülmesi amaçlanmıştır. Çalışma Pedodonti Anabilim Dalı’na başvuran, yaşları beş-dokuz arasında değişen 38 çocuk (12 kız, 26 erkek) hasta üzerinde ürütülmüştür. Kuronlar, aşırı madde kayıplı birinci ve ikinci alt süt azı (n=76) dişine split-mouth tekniği ile uygulanmıştır. 12 aylık takip süresi sonunda iki adet kalibre olmuş değerlendirici tarafından klinik ve radyolojik başarı değerlendirilmiş ve ebeveyn memnuniyeti ölçümü yapılmıştır. Genel klinik başarı oranları 12 aylık takip süresi sonunda PÇK grubu için %100 iken PK grubu için %63 olarak tespit edilmiştir ve aradaki farkın istatistiksel olarak anlamlı olduğu belirlenmiştir. PK kuronlarda “Endodontik sorunlar” ve “kuronların düşmesi” gibi başarısızlıklara rağmen ebeveynlerin memnuniyet derecesinin PÇK’lara kıyasla daha yüksek olduğu bulunmuştur (p<0.05). Tüm klinik ve radyografik değerlendirme kriterlerinde PÇK’nın PK’ya oranla daha başarılı olduğu ancak estetik özellikleri nedeniyle PK’ların daha çok tercih edildiği saptanmıştır. PK grubunda estetik açıdan memnuniyet oranının yüksek olmasına karşılık klinik başarısızlık olarak gözlenen “kuronların düşmesi” ve “endodontik sorunlar” problemlerine neden olma potansiyeli açısından etken olabilecek faktörlerin değerlendirileceği çalışmalara ihtiyaç olduğu düşünülmektedir.
