OBJECTIVE To assess the oral health status and treatment needs of older adults, living in the Valparaiso Region of Chile. METHODS A random sample of 354 older adults, aged 60 years or older, living independently in the community were examined orally by calibrated examiners and underwent a structured oral health interview. Data collection extended from October 2006 to June 2007. RESULTS This was a largely dentate population (80%) with a mean DMFT score of 21.6 (s.d. 5.7). While about 28% of the dentate sample had all their restorative needs unmet, 30.8% had all of their restorative needs met. Regarding periodontal health, 3.3% had sound periodontum; complex periodontal therapy (CPI 3-4) was needed by 43.1% of the sample. CONCLUSIONS This study represents one of the largest data collections in oral health among older adults living in Chile. Participants seemed to have better oral health status than previously reported. Of particular relevance is the reduction of the decayed component and the increased number of sound teeth in the present sample. Participants also presented lower need for advance periodontal treatment. Yet, inequalities were apparent in the proportion of unmet restorative needs. Strategies to develop oral health care programmes focused on improving access to and use of preventive services for older adults are critical. Further research is indicated to get a more complete picture of the factors that shape the oral health of Chilean older adults.
