Aim: This study determined the prevalence and distribution of
pulp stones in the permanent dentition of an adult population
using their periapical radiographs.
Materials and methods: The study followed a cross-sectional
design. A total of 800 periapical radiographs collected from 412
patients attending dental clinics in Kerman, Islamic Republic of
Iran, were examined using magnification.
Results: Pulp stones were present in 9.6% of all permanent
teeth examined, being most common in maxillary first and
second molars, followed by mandibular first and second molars.
They were present in 31.5% of all adult patients, with a significantly
increased prevalence in females compared with males
(40.5 vs 23.9%, chi-squared test p < 0.001). There was also an
increased prevalence with age.
Conclusion: Based on the results of this study, clinicians should
expect to encounter pulp stones most commonly in the pulp
chambers of maxillary first and second molars, particularly in
older female patients.
Clinical significance: Pulp stones depending on their size
and location can pose challenges to endodontic treatment.
They obstruct access to the canal orifices and thus complicate
endodontic treatment. Knowing where and when pulp stones
are likely to occur improves the quality of root canal treatments.
