DOMINGUEZ MEDINA, Nuria; GONZALEZ LOPEZ, Santiago  and  MENENDEZ NUNEZ, Mario. Study of the diffusion ways in the white spot enamel lesion. RCOE [online]. 2002, vol.7, n.5, pp.469-476. ISSN 1138-123X.

The aim of this article is to present and relate the different ways of diffusion of the white spot lesion, its deepness, geometry and peaks of progression. Materials and Method: In the study we used 27 human teeth containing white spot lesions on their free surfaces; the specimens were prepared for visualization under a polarized light microscopy. Results: The histological lesions of enamel caries are wider than deep, with a predomination of triangular shapes presenting more than one peak of progression. The main ways of diffusion are Retzius striae and prism sheaths.
