Aim This multicentred study aimed to investigate
the prevalence of pre-eruptive intracoronal resorption
(PIR) in unerupted teeth of the permanent dentition
using a large sample of panoramic radiographs of a
Turkish population.
Methodology Records of 28 612 patients from
three cities in the different regions of Turkey were
screened retrospectively in this multicentred study.
Patient records and panoramic radiographs were evaluated
by three oral and maxillofacial radiologists in
the sites. The following data were recorded: age, gender,
number of unerupted teeth, number of teeth showing intracoronal resorption, affected tooth type
and number of intracoronal resorptions in each case.
Results Overall, 5554 patients had at least one
unerupted tooth in 28 612 patients, with a prevalence
of 19.4%. Of the 5554 patients screened, 2267
were female and 3287 were male. Intracoronal
resorption was observed in 40 of 5554 subjects, with
a frequency of 0.7%. The mean age of the patients
was 35.9 years.
Conclusion Pre-eruptive intracoronal resorption
defects occurred in 40 subjects. Increased awareness
and careful radiographic examination of unerupted
teeth may improve early detection and treatment of
PIR defects.
