Intra-Examiner Reproducibility of Measuring Gingival Recession Using Three Techniques
Abstract
Introduction: Gingival recession (GR) is typically measured using a periodontal probe (PP), but the measurements obtained with this device have inherent potential for variability. Using Castroviejo calipers (CC) or digital scanning software (DS) to measure GR may increase the preciseness and reproducibility of those measurements. Purpose: The primary goal of this study is to assess intra-examiner reproducibility of GR with the PP, CC, and DS. A secondary aim is to evaluate the practicality of DS as compared to manual alternatives. Methods: GR defects were measured by three different calibrated examiners using PP, CC, and DS. A subset of patients returned for a second appointment to have the same defects re-measured with each device. The intra-examiner reproducibility of each device was statistically evaluated using intraclass correlation with a 95 percent confidence interval. Results: To date, 8 patients with 44 sites of GR have been enrolled. 4 of those patients with 30 sites of GR returned for secondary assessment to determine intra-examiner reproducibility of each device. DS demonstrated an intra-examiner ICC of 0.98, which was higher than that of PP (0.88) and CC (0.88). Conclusion: While clinically acceptable intra-examiner reproducibility may be obtained with any of the three devices studied, the digital scanner offers better reproducibility compared to the UNC-15 or calipers.
