The authors assessed the diagnostic reasons for extraction of 1170 teeth in 565 patients treated in a health community dental centre. They recorded data on the patient's sex and age, on the extracted tooth and reason for extraction. They found that under the age of 30 years permanent teeth were extracter mostly on account of extensive damage by caries and its sequelae. On account of destruction of the periodontium permanent teeth were extracted in patients older than 31 years. At the age of 31-40 years on account of extensive caries and its complications significantly more teeth were extracted in women than in men, at the age above 71 years significantly more teeth were extracted on account of this diagnosis in men, as compared with women. On account of caries and its sequelae 75.7% upper premolars, 69.7% upper molars and 69.9% lower molars were extracted. On account of advanced destruction of the periodontium in the investigated group 80.5% lower incisors were extracted. In other groups of teeth this diagnosis was less frequent.
