Abstract Background Besides the color of the teeth the color of the alveolar gingiva plays a crucial role in esthetic rehabilitation in dento-alveolar treatment. Whereas nowadays the color of the teeth can be determined exactly and individually the specific influence of the red color of the gingiva on treatment has not been assessed yet. The aim of this study was to evaluate the vascularization as the basis for gingival esthetics. Methods Standardized photographs of defined areas of the alveolar gingiva in operated and nonoperated patients were taken and assigned to groups with same characteristics after color comparisons. In addition histologic and immunohistologic analyses of gingival specimens were performed for qualitative and quantitative assessment of vessels and vascularization. Finally colors and number of vessels were correlated. Results Our results demonstrated three different constellations of colors of the alveolar gingiva in healthy patients. The operated patients could not be grouped .
