Abstract

Aim:

The aim was to evaluate the prevalence, distribution, and condition of persistent primary teeth (PPT) among a group of Turkish children.

Materials and Methods:

In this retrospective study, a total of 9632 panoramic radiographies were utilized. The images belonged to patients aged 9–15 years, of which 4301 were female and 5331 were male. Recorded data within the study comprises the age and gender of each patient, total number of PPT observed and for each PPT; its location, presence/absence of a permanent successor, and its status.

Results:

The prevalence of PPT was 4.5% in the Turkish subpopulation. PPT were found more frequently in the maxilla (62.4%) and the most frequent PPT were maxillary canine (42.5%). Only 36.7% of PPT had congenital absence of their permanent successors. Root resorption was the most common condition observed at the presence of PPT (37.9%). Other conditions observed were infraocclusion (11.0%), restorations (10.9%), periapical lesion (4.3%), carious lesion (1.3%), and root canal treatment (0.5%). Besides, tipping was seen in 3.3% of the adjacent teeth of PPT.

Conclusions:

PPT were observed in a significant number of children and adolescents. The most common type of PPT seen on the dental arch was maxillary primary canines. Root resorption and infraocclusion were frequently observed in PPT.
