Abstract
Background and aims. The aim of this study was to investigate the prevalence of permanent teeth extracted due to
periodontal disease and its relation to age, military rank, and type of extracted teeth due to periodontal and non-periodontal
reasons among a group of Greek Army personnel attending a military dental practice.
Materials and methods. Study population consisted of 509 officers, non-commissioned officers and soldiers, aged 18
to 44 years from a military dental hospital in Greece. The reasons for extractions of teeth for a period of two years were
obtained, including aspects such as age, military rank and the type of teeth extracted due to periodontal and non-periodontal
reasons. Data were analyzed using chi-squared test.
Results. The total number of extracted teeth was 1,231, of which 34.4% were extracted because of periodontal reasons,
32.2% for dental caries and 33.4% for other reasons. The average number of extracted teeth due to periodontal disease
showed an increase with age. Maxillary and mandibular first and second molars were the most frequently extracted teeth
due to periodontal reasons; however, the anterior teeth of both jaws with mobility (grade III), the same teeth with attachment
loss (≥5.0 mm) and the posterior teeth of both jaws with furcation involvement (grade IV) were the most frequently
extracted teeth due to periodontal reasons.
Conclusion. Although the goal of the WHO regarding the reduction of dental caries was accomplished, periodontal disease
was still the main cause of tooth extraction and showed an increase with age.
