A Review on the Oral Health Impacts of Acculturation

Abstract

The impact of acculturation on systemic health has been extensively investigated and is regarded as an important explanatory factor for health disparity. However, information is limited and fragmented on the oral health implications of acculturation. This study aimed to review the current evidence on the oral health impact of acculturation. Papers were retrieved from five electronic databases. Twenty-seven studies were included in this review. Their scientific quality was rated and key findings were summarized. Seventeen studies investigated the impacts of acculturation on the utilization of dental services; among them, 16 reported positive associations between at least one acculturation indicator and use of dental services. All 15 studies relating acculturation to oral diseases (dental caries and periodontal disease) suggested better oral health among acculturated individuals. Evidence is lacking to support that better oral health of acculturated immigrants is attributable to their improved dental attendance. Further researches involving other oral health behaviors and diseases and incorporating refined acculturation scales are needed. Prospective studies will facilitate the understanding on the trajectory of immigrants’ oral health along the acculturation continuum.

Related Factors to the Use of Oral Health Services Amongst Population Aged 6 to 15 Years in Colombia

“…Literature has studied how cultural barriers to access to oral health services are related with the capacity of them to provide suitable professionals with cultural abilities to assist different social groups -e.g. minority ethnic groups- (Gao & McGrath, 2011). There exist culturalization processes of the ethnic groups in general societies, which hinder proper integration and thus affect how oral health services are used (Gao & McGrath).…”

Breaking down the barriers: a qualitative study to understand child oral health in refugee and migrant communities in Australia

“…It is likely to depend on the migration experience (i.e. traumatic refugee experiences, access to food, water, sanitation, education), as well as the extent of acculturation that occurs post-migration (Gao and McGrath 2011). Acculturation occurs when groups of individuals of different cultures come into continuous contact, with subsequent changes in the original cultural patterns of either or all groups (Berry 1992).…”
