“…According to BAUMGARTNER et al [16] and KOSHI [20], the gingival color is not affected by cornification. Kosm [20] is of the opinion that the thickness of the epithelium at the apex of the papilla is more responsible than the thickness of the epithelium as a whole.…”

“…Observation of the changes in the color of the gingiva is, therefore, of vital importance in making a diagnosis. The color of the gingiva can be determined by such means as visual color matching [15][16][17], optical instruments [8][9][10][11][12][13][14][15][16][17][18][19][20][21] and colorimetrical analysis of color photos [22][23][24][25].…”

“…The first studies in relation to gingival color were published in the 60's when Ishikawa29 differentiated the color of attached gingiva from the color of marginal gingiva using his own visual guide. Years later, Baumgartner et al30 differentiated between healthy and diseased gingiva: healthy gingiva had a more pink color and diseased gingiva appeared reddish-blue. In 1980, Dummett et al31 stated that facial skin color was related to gingival and mucosal color in approximately 85% of cases.…”

Proposal for a gingival shade guide based on in vivo spectrophotometric measurements

PURPOSEThe purpose of this study was to propose and assess a shade guide for pink gingival aesthetics using a Spanish population sample.MATERIALS AND METHODSThe L*, C*, h, a* and b* coordinates of 259 participants were measured using a spectrophotometer in 3 standardized points along the attached gingiva of the maxillary central incisors. A hierarchical clustering analysis was applied to obtain separate solutions regarding the number of shade tabs. For each of the solutions obtained, color differences (ΔE*) were calculated using the CIELab and CIEDE2000 formulas, and the proposed shade guide was selected considering (1) the color differences between tabs and (2) the coverage error of each of the solutions.RESULTSThe proposed shade guide consisted of 8 gingival shade tabs and achieved CIELab and CIEDE2000 coverage errors of less than the respective 50:50% acceptability thresholds (ΔE*=4.6 units and ΔE00=4.1). The coordinates for the various gingival shade tabs were as follows: Tab 1: L*43.3, a*21.9, b*12.3 (1.6); Tab 2: L*42.9, a*34.1, b*19.1; Tab 3: L*46.5, a*25.8, b*10.9; Tab 4: L*46.5, a*27.3, b*15.1; Tab 5: L*49.6, a*23.5, b*16.8; Tab 6: L*51.5, a*19.7, b*13.6; Tab 7: L*55.9, a*22.0, b* 15.0; and Tab 8: L*56.0, a*19.9, b*18.8.CONCLUSIONThe CIELab and CIEDE2000 coverage errors for the 8 shade tabs of the proposed gingival shade guide were significantly lower than those of other guides. Therefore, despite the limitations of this study, the proposed guide is more appropriate for matching gingival shade in the Spanish general population.

“…Secondly, it is known that plaque re-forms soon after a prophylaxis (Loe et al 1967) and with one exception (Rosling et al 1976), none of the currently practised methods of treatment have been shown to be effective in eliminating plaque and gingivitis for longer than 30 days. Thirdly, the sensitivity and specificity (Thorner & Remein 1961, Lennon & Davies 1975 and the intra-and interexaminer reproducibility in diagnosing early gingivitis are not good (Crowley 1955, O'Leary 1964, Baumgartner et al 1966, Davies et al 1967, Alexander et al 1971, 1972. These limitations were recognized by Ramfjord (1967) who stated that "These needs have never been assessed in a scientific manner and so far no ways have been generally accepted to assess the needs."…”

A longitudinal study was conducted on 106 patients attending a dental school and undergoing periodontal treatment, to assess the relationship between some commonly used periodontal indices and the time taken to treat periodontal disease. The data were analysed by assessing the times taken for examination motivation, scaling and surgery for persons with ranges of indices such as D.I., C.I., O.H.I., G.P.I. (Ging), G.P.I. (Perio), G.P.I. (Comp) and P.I. A one-way analysis of variance was carried out to test the significance of trends. Next, a Spearman correlation coefficient was calculated for each index and its components and treatment time. The index which correlated most closely with examination time was the P.I. The G.P.I. (Ging) was the best predictor of motivation time and three indices, C.I., G.P.I. (Perio) and P.I. correlated significantly with scaling times. The P.I. and G.P.I. (Perio) correlated with surgery time. By converting periodontal indices into treatment times, planners can estimate with a fair degree of accuracy the time and resources required to carry out periodontal treatment for a population.
