The study population consisted of all patients over 60\u2009years of age (n\u00a0=\u00a0216\u2009059) who were treated 2007\u20102015 in public oral health care available to all citizens of Helsinki, Finland. Data for the 9\u2010year time series included reasons for tooth extractions and were aggregated by patient age into 5\u2010year groups.

Mean number of tooth extractions among all patients was 0.4 per patient and 1.7 per extraction patient. Among all tooth extractions (n\u00a0=\u00a082\u2009677), main reasons were caries 29.5%, apical periodontitis 19.4%, tooth remnant 19.4% and periodontitis 18.0%.
