“…In fact, earlier studies carried out in other western countries have reported a poorer oral health status in children and adolescents of ethnic minorities and immigrants living in these industrialized countries compared to the oral health of the national population. Many of these studies were performed in Sweden (Ekman 1990;Wendt & Jonsell 1996;Källestål & Wall 2002), in Denmark (Petersen 1996;Sundby & Petersen 2003), in Great Britain (Laher 1990;Bedi 1991;Todd & Gelbier 1991), in the USA (Ismail & Szpunar 1990;Nurko et al 1998;Cruz et al 2004) and in Australia (Durward & Wright 1989;Marino et al 2001). In Germany, in spite of the large number of immigrants and the dissimilarity in their origins compared with the other host countries, the oral health of migrant and foreign children has not been evaluated adequately.…”
