The association between clinical oral health status and oral impacts experienced by older individuals in Sri Lanka

The aim of this study was to determine the association between clinical oral status and oral impacts experienced by older individuals in Sri Lanka. A total of 585 individuals who were above 60 years and were residents of an urban area was selected using a multistage cluster sampling combined with probability proportionate to size technique. However the present analysis is limited to 235 individuals who were subjected to a clinical oral examination. An interviewer administered Sinhala translation of the Oral Health Impact Profile-14 (OHIP-14) scale was used to assess the oral impacts experienced by the sample. An oral examination was carried out following the interview. Of the 235 subjects clinically examined 64 (27%) were edentulous. The associations between clinical parameters and oral impacts were assessed in the 171 dentate subjects. There were positive, weak but significant correlations between the number of missing teeth, the number of teeth with third degree mobility and the OHIP score. Also those who wore dentures and had halitosis had significantly higher OHIP scores than those who did not wear dentures and did not have halitosis. Logistic regression analysis revealed that 'wearing denture' and 'having halitosis' were significant predictors of the OHIP score. In conclusion, there was a weak association between clinical parameters and oral impacts experienced by these older individuals.
