Aim: The aim of the study was to assess the oral health status and identify oral health perceived and unmet needs, and barriers in utilization of dental services among institutionalized elderly population in Chennai. Materials and Methods: Across sectional study was conducted among institutionalized an elderly population aged 65-74 years. Oral health status was assessed using the WHO Oral Health Assessment Form (2013). Self-perceived oral health needs and barriers in the utilization of dental services were assessed using a pre-tested questionnaire. Descriptive statistics and Pearson Chi Square Test was done to analyse the data. Results: There was a high frequency of periodontitis among the study participants. The unmet oral health needs were high. The self-perceived oral health condition was good among the study participants. The major barrier for utilization of dental services was the lack of information on oral health. Conclusions: In India, which is a developing country, a low level of dental care results from low-level financing of the Indian health care system. This, however, does not mean that even in the current poor economic conditions, it is impossible to improve the dental awareness of the residents of care homes. The improvement is also possible through the inclusion of dental check-ups into the schedule of general dental examinations of the residents performed once in 6 months.
