Özet

Purpose

This study aims to determine the prevalence of dens invaginatus (DI) in maxillary

lateral teeth within a Turkish subpopulation using cone-beam computed

tomography (CBCT) and to evaluate the relationship between the invagination and

the main root canal.

Materials and Methods

A total of 953 maxillary lateral teeth from 662 patients were evaluated for the

presence of DI. To ascertain the invagination's location in the crown from the axial

section, four equidistant areas were delineated, extending from the mesio-palatal

to the disto-palatal surface. Measurements included the vertical distance between

the top of the palatal pulp horn and the buccal pulp horn (h1), the closest distance

between the invagination and the buccal pulp horn (h2), and the dentin thickness

from the widest part of the invagination to the tooth's outer walls.

Results

DI was observed in 5% of the patients (33/662). Invaginations in the medial region

of the mesiopalatinal surface were statistically significantly more common in males

(p=0.049). The distances from the invagination to the buccal and distal walls were

also significantly longer in males (p=0.040 and p=0.008, respectively). There was no

statistically significant difference in the mean distances h1 and h2 according to sex

and age.

Conclusion

Based on CBCT measurements, investigating the presence of DI more

mesiopalatinally in males is recommended to prevent excessive tooth structure

loss. Additionally, given that DI is significantly closer to the buccal and distal walls in

females, a more conservative access cavity approach should be advised to minimize

the risk of perforation.
