Three hundred and forty 5 year old children from 18 state primary schools in Lambeth were examined as part of the BASCD oral epidemiological programme in 2008. The collection of the data was undertaken between February and June 2008. The children were recruited from local state schools using a two stage stratified sampling strategy. The dental examination was undertaken by trained and calibrated examiners and recorded the children’s caries experience, oral hygiene levels and presence of acute infection. Caries was diagnosed at the level of dentinal involvement by visual inspection. No personal demographic data were recorded for the children, though parents and guardians were asked to supply the postcodes of the children’s main residences. The post code of the state primary school was also recorded. The child’s and the school’s postcode allowed the identification of the Index of Multiplied Deprivation (IMD) score and rank of the school the child attended and the child’s residence.

In this study it was hypothesised that children from more socio-economically deprived areas would have more experience of dental caries than children from less deprived areas as measured by the IMD 2007. The IMD is a composite score derived from seven domains (income, employment, health, housing, education, local environment and crime measured using 38 different measures). Each area reflects a local area population of 1500 people. The calculation of the IMD 2007 is based on the Super Output Area (SOAs) and this was according the Government Office for London 2007. There are six measures for the IMD at every local authority level: average score, average rank, extent, local concentration, income scale, employment scale. In this study the measures used fo...

...The Scatter plot was prepared for the depravities variable and the components of the dmft (s). Then the correlation of this study was presented by Spearman’s to test the relationship between the continuous variables of oral health indices and area deprivation (table 4.5) and there was no significant difference between indices

Table 4.5 presents the correlation Spearman’s for the score and the rank of IMD and dental components.
