With the rapid development of medicine, the number of elderly people, and consequently, elderly patients in dental practice, is constantly increasing. Despite the efforts of dentists to educate patients on oral hygiene (to prevent oral health diseases) there are an increased number of people closely related to the physical- and mental-related quality of life, oral disorders such as tooth loss, interpersonal relationships and daily activities and therefore the “well-being” or “quality of life” the goal of contemporary dentistry is to improve oral health, thus improving the overall quality of patients’ life.

Health is a state of complete physical, mental, and social well-being and not merely the absence of disease and infirmity. From this point of view, the ultimate goal in public health is not only the absence of oral diseases but also the mental and social well-being of patients. Oral health has always been considered an important part of the patient’s general health due to the fact that oral diseases can interfere with daily life activities, thus affecting the general quality of life.

According to the World Health Organization, Oral diseases are the most common noncommunicable diseases (NCDs) and affect people throughout their lifetime, causing pain, discomfort, disfigurement and even death and The oral health care demands are beyond the capacities of the health care systems in most low-and middle-income countries (LMICs) and Social determinants have a strong impact on oral health. The population living in slums belong to the low socioeconomic status. According to Hobdell et al., a strong association exists between dental caries prevalence and poor oral hygiene in people Low socioeconomic status. Another study was done by Kothia et al, says that the two most common oral diseases which are very high in India are the  Prevalence of oral cancer with dental caries in the age group of 35 to 44, and 65 to 74-year- old and respectively periodontal diseases in the age group of 35 to 44, and 65 to 74-year-old. The Global Burden of Disease Study 2016 estimated that oral diseases affected half of the world’s population (3.58 billion people) with dental caries (tooth decay) in permanent teeth being the most prevalent condition assessed. (WHO). Most of the Elderly population in slums are non-working and a study was done by Mishra et al., in 2010 also found caries experiences are more in those who are not having any occupation. Behavioural risk factors for oral diseases are shared with other major NCDs, such as an an unhealthy diet high in free sugars, tobacco use and harmful use of alcohol. (WHO).

In this study most common questionnaire will be used to study and evaluate the oral health-related factors as one of the most comprehensive subjective oral health statuses is to measures the self-reported dysfunction, discomfort, and disability attributed to oral conditions. The questionnaire consists of 20 questions which are related to the barriers and factors related to oral health care. All the participants must fill the questionnaire and their response will be recorded for the purpose to obtain and analyze the results of the study.
