Analysis of different type of transmigrant mandibular teeth.

OBJECTIVE

Until recently, most reports about transmigration have documented that the canine is the only tooth which can migrate to the opposite side of the arch. The goal of the study was to define the transmigration of different types of teeth in people in various regions of Turkey.

STUDY

DESIGN

A total of 112,873 panoramic radiographic files from seven different Turkish cities were inspected. The following data were evaluated according to age, gender, number of transmigrant teeth, localization, eruption status, side, unilaterally or bilaterally and associated pathology or dental abnormalities.

RESULTS

Of the 112,873 radiographs included in the study, 90 were seen to present as transmigrant in 87 patients, representing 0.079% of the sample. There were only two (0.0017%) transmigrant lateral (TML) teeth and only three (0.0026%) transmigrant premolar (TMP) teeth encountered. The mean age at the time that the transmigrant mandibular teeth were identified was 29.9 years, with a range from 10 to 66 years. Out of the 87 cases, 51 were female and 36 were male, with a male:female ratio of 1:1.41. Transmigrants were more commonly seen unilaterally (96.5%). The most frequent associated pathology was odontoma.

CONCLUSIONS

Because early detection is vital to prevent complications and ensure more successful treatment, these extensive studies are crucial. In this extensive study, we indicated cases of transmigration of premolar and lateral teeth as a variant. Demographic variables and properties of all transmigrants (TM) were also presented.
