Detection And Quantification

The commonly used clinical methods are inadequate for reliable diagnosis of caries lesions until demineralization is established. By the time a reliable diagnosis can be made, the damage is often irreversible, and restorative methods may be necessary to prevent further progress of the lesions. Early detection of the caries lesion would enable the dentist, by using effective prophylactic measures, to provide remineralization and conservation of the tooth substance rather than restoration of the dentition. Attempts to improve traditional methods or to develop new methods of detecting caries lesions have been numerous. Most of the presently used diagnostic methods require visual observation of an optical signal. Reflected light is used tc detect changes in color, texture, and translucency of the tooth substance. The tools required are a bright light source and a mouth mirror. With special methods utilizing drying, magnification, and photography, the sensitivity of the method can be increased. Various optical methods for the detection and quantification of caries will be discussed - for example, fiber optic transillumination, ultraviolet illumination, the use of various dyes, and fluorescent or non-fluorescent substances to enhance the contrast between the carious and the sound enamel. This presentation will focus on the following two methods: (1) a method that uses visible laser light within the blue-green region as the light source to improve signal-to-noise ratio and increase sensitivity for detection of early caries lesions, and (2) a recently developed quantitative method based on the scattering of light by enamel crystals in relation to their surrounding environment. The possibilities and limitations of the different methods will be critically evaluated. In the near future, optical methods for the detection and quantification of early caries lesions will provide efficient tools for reliable evaluation of caries-preventive measures.

Caries Lesions

Background: Many factors contribute to caries development in humans, such as diet, host factors – including different saliva components – and the presence of acidogenic bacteria in the dental biofilm, particularly Streptococcus mutans (S. mutans). Despite the influence of S. mutans in caries, this bacterium is also prevalent among healthy individuals, suggesting the contribution of genetic variation on the cariogenic potential. Based on this hypothesis, the present work investigated the influence of S. mutans virulence factors and saliva agglutinating capacity on caries susceptibility in children. Study design: Saliva samples of 24 children from low income families (13 caries-free and 11 caries-active individuals) were collected and tested for their ability to agglutinate S. mutans. The bacteria were isolated from these samples and analyzed for the presence of the gene coding for mutacin IV (mut IV). Biofilm formation and acid tolerance were also investigated in both groups (caries-free and caries-active). Results: Saliva samples from caries-free children showed an increased capacity to agglutinate S. mutans (p=0.006). Also, bacteria isolated from the caries-free group formed less biofilm when compared to the caries-active group (p=0.04). The presence of mut IV gene did not differ between bacteria isolated from caries-free and caries-active individuals, nor did the ability to tolerate an acidic environment, which was the same for the two groups. Conclusions: Altogether, the results suggest that the adhesive properties of S. mutans and the agglutinating capacity of the saliva samples correlated with the presence of caries lesions in children.
