A Radiographic Correlation between Renal and Pulp Stones

Area of Science:

• Dentistry
• Nephrology
• Radiology

Background:

• Pulp stones, also known as pulp chamber calcifications, are common findings in dental radiographs.
• The potential association between pulp stones and systemic conditions like kidney stones requires further investigation.

Purpose of the Study:

• To investigate the correlation between the presence of pulp stones and kidney stones.
• To examine associations between pulp stones and demographic and dental factors.

Main Methods:

• Radiographic examination of bitewing radiographs from 116 kidney stone patients and age-matched controls.
• Two oral radiologists identified pulp stones, and statistical tests (Chi-squared, Mann Whitney U) were employed.
• Correlations with age, gender, tooth type, dental arches, and sides were analyzed.

Main Results:

• Pulp stones were detected in 19.3% of examined teeth and 72.4% of kidney stone patients.
• No statistically significant difference in pulp stone presence was found between kidney stone patients and controls (p = 0.882).
• Pulp stones were more prevalent in molars than premolars, with similar distributions across dental arches and sides.

Conclusions:

• This study found no correlation between the presence of pulp stones and kidney stones.
• The findings suggest that pulp stones are not indicative of kidney stone presence in the studied population.
