title: [A polarization-interference method for research on functional stresses in the hard tissues of pathologically worn teeth restored with cast inserts].
abstract: The effect of thickness of casted insertion and parapulpar pins (their dimensions and location taken into account) on the strains in the tooth hard tissues was investigated. The holographic interferometry was applied to distinguish between strains in the sections dentin--insertion and dentin--pin. Holograms and focused images were obtained using dual exposition technique. Interference pictures of the bands of absolute step differences were observed on the holograms as a result of light waves diffraction. The technique allowed to perform a combined investigation of strains with due account of capacity in any part of the tooth hard tissue.
