Clinical Significance Of Increasing The Dentin Colorimetric Color To The Precise Selection Of Cast Porcelain Restoration

Objective: Evaluation of dentine colorimetric to cast the clinical significance of accuratecolor porcelain restoration.Methods: Using conventional colorimetric method and conventional colorimetric methodcombined dentine colorimetry (joint colorimetric method) of30patients with tooth neckone-third cut one-third of color. Repair after2weeks, two groups of casting porcelainrestoration (conventional colorimetric law for the restoration of group A, joint colorimetric lawfor the restoration of group B) as A try adjusted respectively in patients with oral cavity (notbinding), with reference to the contralateral natural maxillary incisors in patients and physiciansfor subjective evaluation to the color of restoration. Collection natural teeth and the digitalimage restoration, image color correction and data acquisition, restoration and natural toothcolor data acquisition.Under CIE1976L*a*b*color system, the two colorimetric method tomake casting porcelain restoration and chromaticity value determination and analysis on theteeth.Using SPSS13.0statistical software of statistical description and analysis of variance.Results: Patients of two groups of restoration color reduction effect degree of satisfactionhas no statistically significant difference (p>0.05). The two groups of restoration chromatismanalysis was statistically significant (p <0.05)Conclusion: Increase the dentine colorimetric to clinically casting porcelain restoration selectionhas certain guiding significance.
