The Relationship between Brushing Teeth and Saliva Conditions on the Accumulation of Calculus in High School Students in Medan city, Indonesia

Abstract

ABSTRACT Brushing teeth is an effort to maintain the cleanliness and health of the oral cavity. This study aims to determine the relationship between brushing and salivary conditions on calculus accumulation in high school students in Medan, Indonesia. Measurements used the Saliva Check buffer kit and atomic absorption spectrophotometer (AAS) to determine the concentration of calcium ions in saliva. The salivary condition assessment parameters measured were calcium level, volume, salivary flow rate, pH and buffer capacity.The results showed that the average volume of saliva was 2.64 + 1.61 ml / 5 minutes, salivary flow rate was 0.52 + 0.32 ml / minute, pH: 7.80 + 0.23 (alkaline), salivary buffer capacity 7.0 + 2.59 (low), calcium content 2.91 + 0.72 Mmol / l, the average frequency of brushing teeth 2 times a day, and calculus index 1.42 + 0.47.The conclusion of this study is that there is no significant relationship between brushing teeth and salivary conditions (volume, flow rate, pH, buffer capacity, calcium ion concentration) on calculus accumulation (p> 0.05).
