Background Developmental hypomineralized lesions of enamel ( DHL ) may represent a significant caries‐risk factor. The aim of this study was to determine the association between carious lesion severity and DHL in 6‐ to 12‐year‐old schoolchildren from Melbourne, Australia. Methods The sample was derived from randomly selected schools in inner Melbourne. A full dental examination was performed at the school. Socio‐demographic data, caries experience ( DMFT /dmft/ ICDAS II ) and the consequences of untreated carious lesions ( PUFA /pufa) were measured. DHL , molar incisor hypomineralization ( MIH ) and hypomineralized second primary molar ( HSPM ) presence were assessed using the European Academy of Paediatric Dentistry ( EAPD ) criteria. Results Of the children examined (n = 327), 26.9% had DHL . The prevalence of MIH and HSPM was 14.7% and 8%, respectively. Almost 20% of children had severe carious lesions ( ICDAS 5 & 6) in at least one permanent or primary tooth. Ordinal regression analyses indicated that DHL ( OR = 2.17; 95% CI : 1.35–3.49) and being born overseas ( OR = 2.59, 95% CI : 1.66–4.06) increased the likelihood of severe carious lesions. Conclusions One of four children had DHL . DHL ‐affected children had an increased likelihood of presenting untreated severe carious lesions compared with DHL ‐free children.
