Abstract Aim of the study: This study aims to assess the tooth mortality in aged population of Bangladesh.Materials and Methods: The study involved 60 elderly individuals aged 50 and above from Rajshahi city and rural areas. The elderly were included regardless of their age, disability, or dentition status. A random sampling technique was used to select subjects. The WHO assessment form was modified to include tooth mobility index, tooth surface loss index, edentulousness, and oral pathology. A questionnaire was used to determine tooth loss, pattern, and causes. The study involved interviews and intra-oral examinations, with data collected and verified daily. The data was analyzed using SPSS-16 software and manual methods, with percentage agreement and student t test used to determine inter examiner variability. The study aimed to improve oral health care for elderly individuals.Result: A study of 60 elderly people aged 50-80 years in Bangladesh found that 66.7% had lost one or more teeth, with a mean tooth loss of 6.9 ± 7.5. The study also found that edentulousness was higher in males (2.2%), females (1.5%), and the elderly (2.1%). The most frequently lost teeth were upper third molars (21% and 21.1%), upper first molars (20.7%), upper second molars (18.9%, 18.3%), lower incisors (16.9%), and upper incisors (17.4%, 16.9%). Caries was not a major cause of tooth loss, but periodontal disease was a major cause, resulting in 83% tooth loss. The most frequently retained teeth were mandibular right canines (92.0%), mandibular left canines (91.7%), mandibular second premolars (89.7%), maxillary canines (87.2%), and maxillary premolars (85.9%).Conclusion: The study shows high tooth life expectancy among elderly in a local government area, with a high percentage retaining more than the required number. Tooth loss causes vary, but caries is not a major issue.
