Brief Summary:

Dental calculus is a calcified deposits firmly attached to teeth and implants surfaces. Dental calculus is strongly associated with periodontitis and considered to have indirect role in the pathogenesis of periodontal diseases. Dental calculus composed primarily of calcium phosphate mineral salts originated in the saliva covered by unmineralized bacterial layer. Composition of calculus varies from person to person and influenced by numerous variables such as: age, gender systemic disease and ethnic background.

Nephrolithiasis (kidney stones) are composed of insoluble salts of constituents of the forming urine. The most two frequent stone types are: Calcium oxalate (with a frequency of 15% -35%) and Calcium phosphate (5% -20%). The prevalence of kidney stones varies with race, sex, and geographic location. In the United States for men, kidney stone rates vary between 4%-9%, and for women, kidney stone rates range between 2%-4%.

Previous studies dealt with the connection between sialolithiasis and nephrolithiasis were inconclusive. To the authors' best knowledge no studies were done to examine the associations between nephrolithiasis and dental calculus. Thus, the aim of this study is to compare the mineral composition of both dental calculus and nephrolithiasis and determine whether nephrolithiasis composition may be linked to the periodontal status.
