Abstract
ABSTRACTBackground: Dental caries is a wide spread chronic multifactorial disease. The secretion rate and quality of saliva areimportant factors not only in caries development but also for remineralization. The aim of this study was to measurethe severity of dental caries among a group of 22-23 years old adults in relation to salivary flow rate, calcium andphosphate ions in unstimulated and stimulated saliva.Materials and methods: Unstimulated saliva was collected from one hundred healthy adults (males and females) firstthen the stimulated saliva with one hour interval. The sample was divided into three groups (mild, moderate andsevere) according to (DMFS). Salivary flow rates were estimated as ml/min. Calcium ions were assessed using AtomicAbsorption Spectrophotometer, while inorganic phosphate ions concentration were determined by Molybdenum-Vanadate method using Ulteaviolet visible spectrophotometer.Results: Highly significant difference of unstimulated salivary flow rate means was found among DMFS caries severitygroups, recording highest mean in mild group with non significant correlations with DMFS. In relation to stimulatedflow rate, significant difference was seen among DMFS severity groups, recording the highest mean within mild groupand highly significant negative correlations with DMFS. Unstimulated salivary calcium showed highly significantdifferences among DMFS severity groups, where the highest means were in the severe group and recorded highlysignificant correlations with DMFS, while phosphate recording non significant differences among DMFS severitygroups and non significant negative correlation with DMFS. In stimulated saliva, calcium showed highest mean valueswith highly significant differences in severe DMFS caries severity groups with highly significant correlation with DMFS,while phosphorus had significant highest mean within severe DMFS group and recorded non significant correlationwith DMFS.Conclusions: The study showed the importance of stimulated salivary flow rate in reducing dental caries severity.Keywords: Dental caries, salivary flow rate, salivary calcium, salivary phosphate.
