“…This system can be used to take direct images from the oral cavity or from models created after impressions are taken from the patients [21]. Recently, this technique was successfully used for volumetric analyses after gingival recession treatment [22]. In another study, Wiranto et al [19] reported that intraoral scanning is a valid and reliable method with high reproducibility for diagnostic measurements in the field of dentistry.…”

Background An apical shift in the position of the gingiva beyond the cemento-enamel junction leads to gingival recession. This study aimed to evaluate the reproducibility of digital measurements of gingival recession when compared to conventional measurements taken clinically using periodontal probes. Methods Gingival recession was measured at 97 sites in the oral cavity by four examiners using the following methods: CP, direct measurement of gingival recession using William’s periodontal probe intraorally; CC, measurements on cast models using a caliper; DP, digital measurement on virtual models obtained by intraoral scanning, and DC, digital measurements on virtual models of dental casts. Intra-class and inter-rater correlations were analyzed. Bland Altman plots were drawn to visually determine the magnitude of differences in any given pair-wise measurements. Results In this study, good inter-methods reliability was observed for almost all the examiners ranging from 0.907 to 0.918, except for one examiner (0.837). The greatest disagreements between the raters were observed for methods; CP (0.631) followed by CC (0.85), while the best agreements were observed for methods DP (0.9) followed by DC (0.872). Conclusion Variations in measurements between examiners can be reduced by using digital technologies when compared to conventional methods. Improved reproducibility of measurements obtained via intraoral scanning will increase the validity and reliability of future studies that compare different treatment modalities for root coverage.

Digital scanners are currently use in various fields of dentistry such as prosthodontics, dental implantology, orthodontics, with a high degree of accuracy, mostly for replacing conventional impressions. The aim of the present study was to assess the accuracy (trueness and precision) of gingival margin measurements, on virtual models obtained by intraoral scanning, for precise diagnosis and treatment monitoring of periodontal disease. Three methods were compared for accuracy: clinical measurements using periodontal probes, digital intraoral scanning and measurements in MeshLab software and 2D digital measurements on intraoral photography taken during clinical measurements. Intraoral scanning was proved to be a reliable method for measuring the gingival level for diagnosis and clinical monitoring having a good accuracy as compared to the gold standard (clinical measurements).
