Paper Abstract

In this research results of approbation of the optical PNC- method in dental clinic are presented. The PNC-method was used for diagnostics stages of caries (initial, moderate and deep). The variant of the PNC-method adapted for dental diagnosis is based on simultaneous analyses the following parameters by special algorithms: backscattering and probing radiation, stimulated (endogenous) autofluorescence of caries induced batteries. Analyze of informational signals show good correlation with tooth morphological structure and concentration of anaerobic microflora in hearth of caries lesion. Investigation was performed in vivo on 101 tooth in conditions of typical dental clinic. Comparison of the PNC- method with visual and X-ray ones, which are widely used in clinical practice was made. Preliminary results showed high potential of usage the PNC-method in clinical practice and more high probability of initial caries detection (up to 100%) in comparison with X-ray method (approximately 75%). In cases when X-ray diagnosed absence of initial caries, more sensitive the PNC-method detected initial caries in stage 'white lesion.'
