Evaluation of gingival recessions with conventional versus digital methods

Gingival shape analysis using surface curvature estimation of the intraoral scans

“…In periodontology, digital evaluation predominantly means just the digitalization of the established evaluation methods [42]. Only recently, curvature analysis was used for segmentation of teeth [43][44][45] and to detect anatomical landmarks, i.e., cemento-enamel junction and gingival margin, to automate gingival recession measurements [46] and evaluate changes over time [20,35]. Surface curvature estimation utilised for the palatal soft tissue shape quantification [28] and the results of the present study indicate that surface curvature estimation of optical scans presents a suitable method for soft tissue shape analysis.…”

“…In periodontal research, optical scanning enabled novel and accurate evaluation methods, such as volumetric assessment of soft tissue dynamics [17][18][19]. Recently, computer-aided analysis of optical scans revealed considerably improved accuracy of linear measurements of dimensional differences of soft tissues after different treatment procedures compared to evaluation with periodontal probe [20][21][22][23]. Furthermore, optical scans also present a possibility for shape analysis, successfully implemented in medical image analysis to aid in detecting and diagnosing [24][25][26].…”

Anatomical assessment of the trabecular structure of the alveolar bone in periodontal disease by fractal analysis method

“…(Figure 1) (3). The stages of gingival disorders can start as gingivitis and progress to advanced periodontitis (Figure 2) (4)(5)(6). Periodontitis and osteoporosis are known to be common inflammation-related skeletal system disorders.…”
