Background: Dental calculus is a form of hardened dental plaque of both inorganic (mineral) and organic (cellular and extracellular matrix) components. Whereas kidney (renal) calculi is a solid concentration or crystal aggregation formed in the kidneys from dietary minerals present in urine.
Aim & Objective:The study aimed to investigate and explore the relationship between dental calculus formations among recurrent renal calculi formers. The objective was instigated due to the multiple shared features and the high prevalence of formation factors and the calcification process of dental calculus and renal calculi.
Methods & Materials:The study was comprised of 65 patients of the lithotripsy clinic participated in the study; all volunteered after reviewing and accepting the study's proposal. The control group consisted of 31participants whilst the study group had 34 participants. Oral examination was carried out for both groups using the gingival index, plaque index, and oral hygiene index--calculus index, debris index. Saliva and urine samples were obtained to measure the levels of Calcium (Ca), phosphate (P), magnesium (Mg) and pH. Results: Plaque, Calculus and Gingival Indices showed High mean values among study group with significant differences compared to control group. Saliva and urinary samples resulted lower magnesium ions in the study group but not statistically difference compered to the control one, while high scores of calcium and phosphorus ions were found in the study group. Conclusion: After laboratory investigations and bio statistical analysis a relation has been found linking both conditions. In light of this result, urologist are advised to refer these patients to have follow up sessions in dental clinic to maintain their oral health.
