Periodontal disease is characterised by gingival inflammation loss of connective tissue attachment and bone loss. These changes are associated with pathologic tooth migration. The aim of the study was to assess the prevalence of pathological migration in patients with periodontitis. Retrospective data collection was conducted from June 2019 to March 2020 among 157 patients with generalised chronic periodontitis who reported to the Department of Periodontics, Saveetha Dental College and Hospitals, Chennai. Both clinical and radiographic images were used to assess the presence and type of pathological migration and the results were analysed. Among the various types of pathological migration studied like diastema, crowding, spacing, mesial tilt and distal tilt, it was found that spacing between the teeth (53 sites) was the most common and the distal tilt of the tooth (5 sites) was the least common type of pathologic migration.
Key words: Midline diastema, Pathologic migration, Periodontitis, Tooth position.
