Description
Summary:International Journal of Paediatric Dentistry 2010; 20: 400–409 Background.  Dental erosion (DE) in children is a significant oral health issue and has become a focus for research in clinical paediatric dentistry. Aim.  This study investigated DE in the primary dentition of 2‐ to 4‐year‐old twin and singleton children with regard to the genetic, medical and dietary factors associated with the condition. Design.  The 128 subjects consisted of 88 twin children (31 monozygous, 50 dizygous, 7 unknown zygosity) and singletons (n = 40) aged 2–4 years. Medical, dental, and dietary histories were obtained. The children were examined for DE using a modified index. Results.  The prevalence of DE by subject affected was 77% in monozygotic twins (MZ), 74% in dizygotic twins (DZ), and 75% in singleton controls (P > 0.1). Of the teeth scored, 12% had mild, 10% moderate, and 1% severe lesions, and DE was more severe in the older age group (P
