Fluorosis and caries in prehistoric populations of Papua Indonesia

Abstract

This study examines the prevalence and association of two major dental pathology-fluorosis and caries- in prehistoric populations from Papua, Indonesia. A total of 73 teeth from 55 individuals were analyzed using the Tooth Surface Index of Fluorosis (TSIF) alongside standard diagnostic methods for detecting caries. The study involved examining the teeth using Novex Holland, and Bresser microscopes, followed by the application of statistical methods, such as Pearson’s correlation and linear regression, to analyze the relationship between fluorosis and caries. The findings revealed high rates of fluorosis, whereas caries appeared less frequently. These outcomes suggest a potential inverse correlation, likely resulting from prolonged fluoride intake through naturally sourced water. This research offers valuable insights into the oral health of ancient populations and highlights the importance of further studies on how environmental and biological elements influence dental diseases in tropical climates.
