Determination of Prevalence and Etiologic Factors of Black Tooth Stains in Children
Project no. 410 · Status: Kapanmış · 2017
Summary
Black tooth stains is a common clinical finding in children. Unlike other discolorations, it contains insoluble iron salts and a high proportion of copper, calcium and phosphate. Dominant microorganisms in black stains have been reported as Actinomyces spp. and Prevotella melaninogenicus. The aim of this study is to investigate the prevalence and etiologic factors of black tooth stains in 1000 patients between 3-12 years of age. A questionnaire was applied to the parents of patients in the study and control groups in order to evaluate socio-demographic status, systemic condition, professional dental care, oral hygiene and feeding habits. Black tooth stains and dental plaque samples were taken from the patients included in the study after oral examination. Microbiological analysis were performed at Ege University, Faculty of Science, Department of Biology Industrial Microbiology Laboratory. The data were evaluated statistically by Shapiro Wilk test, Levene test, Student-t test, Mann Whitney-U test, Fisher Exact Test, Chi-square test and Monte Carlo simulation method. As a result of the study, the prevalence of black tooth stain was found to be 4.4%. It was determined that black tooth stains increased with iron drug use in children. As the number of carious teeth increased, the likelihood of black tooth stain decreased. There was no statistically significant relationship between S. mutans and Actinomyces spp. and black tooth stains, but black tooth discolorations revealed a lower number of Lactobacillus spp.. Further studies are needed in order to reach the wider masses reflecting the society about black tooth stains in children and to examine more microorganisms in detail.
