Abstract: | Abstract. Objective: The purpose of the hereby paper consisted in the study of particularities of the chemical composition of dental enamel in
children suffering from severe neuromotor disabilities associated with gastro-esophageal reflux disease (GERD). Material and methods. Using
the Fourier transform spectroscopy method (FTIR) we have studied the structure and the chemical composition of various areas of the dental
enamel, namely 64 pieces of enamel prepared from 32 teeth extracted from children aged between 13 and 17, following orthodontic indications.
Results: We established that in the enamel of the children suffering from severe neuromotor disabilities associated with GERD the weight of
the organic component of enamel is increased, the content of hydroxyapatite content is reduced, it contains carbon substituted hydroxyapatite
with low intensity of peak phosphorus and significant increase of organic components. The detected particularities of the chemical composition
of dental enamel indicate the considerable reduction of the enamel resistance to acid attack, thus leading to a high risk of dental erosion or new
carious lesions. Conclusions: The FTIR spectroscopy method of dental enamel offers new opportunities in the study of pathogenic mechanisms
involved in the initiation and evolution of carious lesions and dental erosions, to make a prediction of these disorders, to elaborate measures for
the prevention of tooth decay and evaluate their efficiency |
