Intra-operator Reliability of a 2D Image Analysing Method for Tooth Dimension Measurements

DOI: 10.2478/amma-2014-0024

Objective: The aim of this study was to evaluate the intra-operator reliability of a 2D image analysis method for tooth dimension measurements.
Methods: Occlusal and vestibular surfaces of teeth from ten study models were captured with a digital camera. Images were transferred on a computer and different tooth dimensions (mesio-distal, occluso-gingival, vestibulo-oral and perimeter) were measured using the Image Pro Insight software. Measurements were repeated after two weeks. Fleiss’ coefficients of reliability were calculated.
Results: A high degree of reliability has been established for every type of measurement: all coefficient values of reliability being not less than 0.95.
Conclusions: The 2D image analyzing system is an adequate alternative for measuring tooth dimensions. All measurements were in the excellent category of reliability. The method allows precise and repeatable measurements, generating an image database as well, available for future studies.
