Abstract:

Objective To study the consistencyamong four methods for measuring oral vestibular groove depth (OVGD). Methods Sixteen subjects were selected, and four measuring methods were used:silicone rubber mold measurement(SMM), alginate mold measurement(AMM), intra-oral direct measurement(IDM), and oral scan measurement(OSM). Three examiners(A, B, C)measured the vestibular groove depth of 16, 14, 11, 46, 44, and 41 tooth positions respectively. Results The consistency among the three examiners was nearly perfect(ICC=0.87), and the consistency among the four measuring methods was moderate(ICC=0.49). Results of the four measuring methods were IDM>SMM>OSM>AMM from the largest to the smallest.Bland-Altman plots showed good consistency among examiners and poor consistency among measuring methods. Conclusion Among the four methods of measuring oral vestibular groove depth, examiners have little influence on the results, and the results obtained by different methods are different.

Key words: oral vestibular groove depth, measurement, consistency
