    Summary
    This summary is machine-generated.

    Undergraduate dental students showed limited accuracy in matching gingival shades using a computer application. The available porcelain shades did not adequately represent natural gingival colors, impacting shade selection precision.

    Area of Science:

    • Dental materials science
    • Esthetic dentistry
    • Color science in dentistry

    Background:

    • Accurate gingival shade matching is crucial for esthetic dental restorations.
    • Existing shade guides may not fully represent the diversity of natural gingival hues.
    • Evaluating digital tools for shade selection is an emerging area in dentistry.

    Purpose of the Study:

    • To assess the accuracy of undergraduate dental students in matching gingival shades.
    • To evaluate the effectiveness of a computer application for gingival shade selection.
    • To determine the adequacy of available porcelain shades for representing natural gingival colors.

    Main Methods:

    • 76 undergraduate dental students participated in the study.
    • An in-house developed computer application was used for shade selection.
    • 15 intraoral gingival photographs and 21 porcelain shade samples were utilized under standardized conditions.

    Main Results:

    • A significant portion of porcelain samples (66.6%) were not representative of studied gingival shades.
    • Natural gingival colors were not consistently represented within the acceptability limits of the porcelain samples.
    • No statistically significant gender-based differences were found in overall shade matching accuracy.

    Conclusions:

    • The current ceramic system's shade palette is insufficient for accurate subjective gingival shade selection.
    • Gingival color perception did not differ significantly between male and female dental students.
    • The L* coordinate (lightness) was the sole significant factor influencing correct gingival color perception, with a slightly greater impact on female students.
