  • Title: The microcrystal alignment in human tooth enamel from carious and non-carious teeth in relation to caries susceptibility.
    Author: Martens LC, Verbeeck RM, Callens FJ, Matthys PF, Driessens FC, Dermaut LR.
    Journal: J Biol Buccale; 1986 Mar; 14(1):65-8. PubMed ID: 3009428.
    Abstract:
    The degree of microcrystal alignment in the intact enamel from carious and non-carious upper incisors, lower incisors and upper canines was determined by means of electron paramagnetic resonance. The results show that a low degree of alignment is not a generally valid indication for caries-susceptibility. Upper canines have a high degree of crystallite alignment whereas lower incisors have a relatively low one. With the exception of the upper central incisors no differences in microcrystal alignment are found between the intact enamel from carious and non-carious lower incisors and upper canines. These results indicate that a possible caries-susceptibility of tooth enamel reflected by low R-values is not solely determined by the degree of microcrystal alignment.
