This study aimed to quantify the prevalence and extent of infraocclusion in singletons and twins during the late mixed dentition stage of dental development using a new diagnostic imaging method and objective criteria. The study also aimed to determine any associations between infraocclusion and gender, arch type, arch side and tooth type.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Two samples were analysed, 1454 panoramic radiographs of singletons and 270 dental models of twins. Both samples ranged in age from 8 to 11 years. Adobe Photoshop <jats:styled-content style=\"fixed-case\">CS<\/jats:styled-content>5 was used to measure the extent of infraocclusion. Repeatability tests showed systematic and random errors were small.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The prevalence in the maxilla was low (&lt;1%), whereas the prevalence in the mandible was 22% in the singleton sample and 32% in the twin sample.
