Introduction: Relationship between periodontal infection and pulp pathosis has been debated for many years. This human case control study was performed to evaluate the possible effects of moderate to advanced chronic periodontitis on pulp stone formation and pulpal calcifications.

Methods: Current study is an experimental case control study.  Samples included 23 hopeless permanent teeth, affected with periodontitis in the case group and 23 periodontally healthy teeth in the control group, which were extracted for reasons like full denture treatment plan. After extraction and sectioning the apical 2-3 mm of root, teeth were immersed in 10% Formalin solution for 7 days. Then, teeth were decalcified in 5% HNO3 for 10 days. After implementation of tissue preparation steps, sections were made of apical, middle and coronal part of root of each sample. After histological processing, sections were examined by an experienced pathologist under a light microscope. Prescence of pulp stone was investigated in the sections and the results of the two groups were compared with each other.

Results: Frequency of pulp stone showed no significant differences between the case and control groups in non of sections. (P-value= 0.730, 0.300, 0.760).

Conclusion: Inflammation of periodontium in chronic periodontitis has no influence on pulp stone formation.
