The coastal region is the largest region in Indonesia as a country of the archipelago. Characteristics of groundwater content in coastal areas are very influential on dental health, especially dental caries. The main elements contained in 1-1000 mg/litre groundwater are calcium, magnesium, sodium, potassium, chlorine, bicarbonate, and sulfate groups. Calcium is an essential ingredient for living organisms that play a role in the formation of bone and tooth along with permeability of cell walls.
This study aimed to analyse the relationship between calcium in groundwater with dental caries.
Analytical observational study with cross-sectional approach was implemented was coastal communities in Watu Ulo Jember Regency in February 2018 (3,686 inhabitants), with sample criteria of the minimum age of 12 years and consumed groundwater as drinking water at least 2 years by purposive side. The variables in this study were calcium levels as the independent variable and dental caries as the dependent variable. Calcium was measured using the spectrophotometric method. Caries measurements were performed using the DMF-T index. Data were presented descriptively in the table and analysed by Spearman Correlation test to analyze the relationship between groundwater calcium with dental caries.
Average groundwater calcium content was 126.75 mg/litre (high category), and average dental caries was 2.2 (low category). Spearman correlation analysis showed p = 0.029 (p < 0.000), which means there was a correlation between groundwater calcium level with dental caries.
There is a positive relationship between the calcium content of groundwater with dental caries.
作为一个群岛国家，沿海地区是印度尼西亚最大的地区。沿海地区地下水的成分特征对牙齿健康，尤其是龋齿，有着很大的影响。每升地下水中所含的主要元素为钙、镁、钠、钾、氯、碳酸氢根和硫酸根。钙是生物体的必需成分，在骨骼和牙齿的形成以及细胞壁的通透性方面发挥作用。
本研究旨在分析地下水中的钙与龋齿之间的关系。
于2018年2月在任抹县瓦图乌洛的沿海社区开展了采用横断面方法的分析性观察研究（3686名居民），样本标准为年龄至少12岁且至少饮用地下水2年的目标人群。本研究中的变量为作为自变量的钙含量和作为因变量的龋齿。采用分光光度法测量钙含量。使用DMF-T指数进行龋齿测量。数据在表格中进行描述性呈现，并通过Spearman相关性检验分析地下水中的钙与龋齿之间的关系。
地下水中钙的平均含量为126.75毫克/升（高类别），龋齿的平均发生率为2.2（低类别）。Spearman相关性分析显示p = 0.029（p < 0.000），这意味着地下水中的钙含量与龋齿之间存在相关性。
地下水中的钙含量与龋齿之间存在正相关关系。
