Methods The study sample consisted of 1 515 65～74 year old subjects recruited through multi stage cluster sampling. The subjects were interviewed by trained interviewers. Clinical examination procedures and diagnostic criteria used following those recommended by World Health Organization. Results Mean number of missing teeth (MT) and teeth indicated for extraction (IMT) were found to be 11 9 and 2 5. Greater IMT were found in rural residents. ANCOVA analysis indicated that tooth loss was associated with socio economic factors and gender. 4% of the elderly were completely edentulous and 47% of the elderly were found to have dental prostheses in either jaw. Only 49% of the elderly had eight or more occluding tooth pairs. Conclusion The functions of the dentitions of around half of Guangdong elderly were not acceptable and effort should be made to reserve their natural teeth.
