COMPARISON OF THE METHOD OF ELECTROMETRIC DETERMINATION OF ROOT CANAL PARAMETERS AND THE METHOD OF THRESHOLD SEGMENTATION OF RADIOGRAPHS

The subject matter of the article is X-ray images teeth during endodontic operations. goal work to compare developed method segmentation radiograph determine length root canal with electrometric and mathematical methods in practice. uses following methods: principles preparation teeth; determining working (radiological, electrometric); threshold method; bone structures on tomographic images. results were obtained: existing analyzed, main advantages disadvantages each highlighted. fast, but inaccurate can only serve as a preliminary estimate. Electrometric most accurate, has very strict requirements for measurement area moisture, well invasiveness number disadvantages. Radiological promising research because its painlessness patient, low radiation dose intraoral radiography possibility using image processing algorithms refine results. This formulated extraction tooth contours conducted practical studies all analysis. Conclusions. application determination gives accurate result, allows doctor obtain additional information about architectonics canal. As such segmentation, contour automatic apical constriction zone make this perspective. optimal combination these two practice, which requires research.
