Objective: To record reasons for the extraction of teeth and teeth remaining at one dental practice. Method: Data was collected consecutively from all patients attending the practice for tooth extraction over a period of thirteen years. Reasons for extraction were taken from a list of extraction codes. Data was also recorded for the date of extraction, age of patient, tooth extracted and whether it was root treated. Also recorded were the number of teeth extracted at the appointment, the number of functional pairs and the number of teeth remaining. Result: One thousand and twenty !ve teeth were extracted, 38% (95% Con!dence Interval [CI] 35-41%) because of periodontal disease, 33%, (95% CI 30-36%) because of recurrent periapical infection and 10% (95% CI 8-12%) because of root fracture. Other reasons included fractured tooth crown, caries, root perforation, to create occlusal clearance, appearance, orthodontics and lastly treatment planning. Sixteen per cent of extracted teeth were non-vital. Of the numbers of functional pairs, 15% had none and just over a third had 11,12 and 13 functional pairs. The majority of patients (72%) were aged 55 years and above and 46% were above 65 years old. Conclusion: Periodontal disease closely followed by recurrent periapical infection were the main causes for the extraction of teeth in this cohort of patients. Under half of all patients had su"cient teeth for function (i.e. 10 functional pairs of teeth) and almost half were elderly (>65 years old), with a likely increased need for prosthodontic rehabilitation in future.
