Photometric CIELAB Analysis of the Gingiva: A Novel Approach to Assess Response to Periodontal Therapy

Abstract

Results of this study suggest potential benefit in using photometric analysis to assess gingival changes after therapy.

Plaque‐induced gingivitis: Case definition and diagnostic considerations

“…In an attempt to circumvent the subjectivity of examiner scoring, non‐invasive methods based on digital technologies were introduced more recently. These methods mainly aim at measuring the volumetric or color changes that occur in the gingival tissues due to plaque‐induced inflammation . Although their application would be highly desirable in the diagnosis of gingivitis, no histologic validation of these instruments is currently available.…”

“…Although their application would be highly desirable in the diagnosis of gingivitis, no histologic validation of these instruments is currently available. Moreover, few studies have evaluated their reliability in subjects with gingivitis . While some studies reported a positive association between the gingival volume and GI changes (without reporting the statistical strength of the association), other studies failed to find a significant correlation between colorimetric assessments and variations in GI .…”

Plaque‐induced gingivitis: Case definition and diagnostic considerations

“…These methods mainly aim at measuring the volumetric or color changes that occur in the gingival tissues due to plaque-induced inflammation. [49][50][51][52][53][54][55][56] Although their application would be highly desirable in the diagnosis of gingivitis, no histologic validation of these instruments is currently available. Moreover, few studies have evaluated their reliability in subjects with gingivitis.…”

“…Moreover, few studies have evaluated their reliability in subjects with gingivitis. 49,54,56 While some studies reported a positive association between the gingival volume and GI changes (without reporting the statistical strength of the association), 49 other studies failed to find a significant correlation between colorimetric assessments and variations in GI. 56 Moreover, additional aspects, including need for standardized conditions for their use, restriction of colorimetric assessments to the buccal attached gingiva of anterior teeth and need for specific adjustments for colorimetric evaluations of pigmented gingival tissues in specific ethnic groups, limit the potential to apply these technologies reliably or pragmatically to define a GC.…”

Relative Translucency of a Multilayered Ultratranslucent Zirconia Material

“…This method has been used in various investigations to assess differences in color perception between teeth, 19 shade guides, 20,21 and observers. 22,23 Moreover, image analysis is applied in shade matching, [24][25][26] communication between dentists and laboratory technicians, 27,28 diagnosis of gingival inflammation, [29][30][31] oral lesions detection, 32 and evaluation of bleaching results. [33][34][35][36][37] A very high and statistically significant correlation was found between the spectrophotometer and digital imaging analysis for all CIE L*a*b* color values.…”
