Purpose

The aim of this study was to investigate
the prevalence and characteristics of ectopically erupting first permanent
molars (FPMs) in children attending the clinics of the Pediatric Dentistry
Department at İstanbul University. 

Materials and methods

This retrospective study was performed
using panoramic radiographs of 7,649 patients (3,506 females and 4,143 males)
aged from 5 to 11 years. The age and gender of the subjects, the number and
location of the ectopic molars, bilateral versus unilateral occurrence, the
degree of resorption of the roots of the primary molars, and other associated
dental anomalies were assessed. Ectopic eruption was categorized according to a
grading system based on the resorption rates of the primary molars. 

Results

Of the 7,649 reviewed subjects, 203 (118
males and 85 females) were diagnosed with ectopic eruption of the FPMs,
resulting in a frequency of 2.65%. The mean age of the subjects with ectopic
FPMs was 6.82±1.25 (range: 5–11) years. Of the 273 ectopic FPMs, 157 (57.5%)
were detected in the maxilla and 116 (42.5%) in the mandible. Severe and very
severe degrees of ectopic eruption were found to be more common in the maxilla
than in the mandible, whereas a moderate degree of ectopic eruption was more
prevalent in the mandible (p=0.251).

Conclusion

To our knowledge, this is the first study
in a Turkish population reporting the prevalence of ectopic eruption of FPMs.
Although the difference between the right and the left sides was not
significant, the severity of ectopic eruption was different between the maxilla
and the mandible.
