Ultrastructural changes of the initial lesion at early childhood caries

Despite evident reduction of caries in many countries,where complex programs for prevention are carried out,the prevalence of early childhood caries (caries infantile) expresses continual growth trend. ecc is often found under the name connected with the manner of feeding and nutrition of children such as baby bottle syndrome or baby bottle caries. the aim of the research is to determine precisely the ultra-structural changes in the enamel substance at the initial lesion (white spot lesion),because the changes are of great importance for the preventive aspect of this early childhood disease. the experiment evaluated the ultra-structural changes of the teeth enamel in primary teeth with circular caries in its starting stage of development-initial caries lesion. the patients (age 6) with deciduous teeth already in the phase of resorption,were chosen carefully. we extracted 10 maxillary incisors with initial lesion,and 20 healthy mandibular incisors,as a control group. examination of the surface was made with scanning electronic microscope (jsm 5300,jeol),at the institute for biomedical research of the faculty of medicine in nis (serbia). during the analysis of experimental samples,the enamel surface at the initial lesion,was observed. demineralization of enamel surface happened at the place of initial lesion. prismatic ridges were rounded and melted,and inter prismatic spaces were expanded. the results from this research speak in favor of better understanding of ultra-structural changes on the enamel surface,in the initial phase of early childhood caries. this could help in creation of the strategy for its successful prevention.
