Dental calculus in relation to idiopathic calcium renal stone

Abstract

Background: Dental calculus is a form of calcification process that occur in the oral cavity and due to its similarstructural composition with calcium renal stone, so dental calculus formation may increase in those patients withcalcium renal stone. This study conducted to evaluate if there is a relation between dental calculus accumulationwith calcium renal stone formation by investigating the relations of oral hygiene and gingival health status withurinary and salivary physical properties and constituents then comparing the results with healthy looking subjects.Materials and Methods: Thirty patients with idiopathic calcium renal stone selected as study group with an agerange (25-30) years and 30 gender and age matched healthy looking persons selected as control. Plaque Index ofSilness and Loe and Calculus Index component of Simplified Oral Hygiene Index of Green and Vermillion recordedoral cleanliness while Gingival Index of Loe and Silness recorded gingival health status. Urinary and stimulatedsalivary samples collected and chemically analyzed to determine the concentrations of calcium, phosphorus,magnesium and urinary creatinine. The pH and buffer capacity of saliva also estimated in this study.Results: Higher mean values of Plaque, Calculus and Gingival Indices scores recorded among study group with highsignificant differences compared control one, positive high significant correlation recorded between dental plaquewith calculus accumulations among study group, higher mean values of salivary pH and buffer capacity recordedwithin study group with high significant difference compared control one, positive significant correlation recordedbetween calculus accumulation with salivary pH among study group, high significant elevation in the concentrationof salivary phosphorus while high significant reduction in salivary magnesium concentration recorded within studygroup compared control one, significant correlations recorded between calculus accumulation with urinaryconstituents.Conclusion: presence of significant correlations between dental calculus accumulations with calcium renal stoneformation, so special oral health preventive programs are needed for those patients
