    The objective of this study was to determine the location of the gingival zenith in relation to the vertical axis of the upper anterior teeth and the lateral incisors in relation to the gingival zeniths of the adjacent proximal teeth. Methodology: A total of 44 patients treated at the Advanced Dentistry Clinic San Marcos between October and November 2022 were evaluated. These patients were asked to participate in the study by signing an informed consent form. With their authorization, an alginate study model was taken, which was immediately poured with dental stone. The gingival zenith analysis was performed on the study model, where various tracings were made to identify the gingival zenith, its location, and its displacement in millimeters from the vertical axis of the dental piece, as well as its position relative to the adjacent teeth. Results: The location of the gingival zenith relative to the vertical axis for the upper central incisors was 1.01 mm and 0.99 mm, while for the lateral incisors, it was 0.70 mm and 0.80 mm, and for the canines, it was 0.50 mm and 0.48 mm. Additionally, the right and left lateral incisors showed a distance of 0.90 mm and 0.85 mm from the tangential line formed between the zeniths of the central incisors and canines. Conclusion: The gingival zeniths of the right and left central incisors, lateral incisors, and canines were mostly found towards the distal, while the lateral incisors were mostly found towards the coronal of the tangential line formed by the zeniths of the adjacent teeth.

    Two-dimensional analysis, geometric shape and gingival zenith in anterosuperior teeth in patients attending the dental office, Dental Estudio in the year 2022
    (Universidad Privada Norbert Wiener, 2023-10-13) López Aguilar, July; Guevara Sotomayor, Juan César
    A total of 36 individuals who met the inclusion criteria were evaluated at the 'Dental Studio' dental office. These patients were asked to participate in the research by signing an informed consent. With their authorization, a study model was taken using alginate, which was immediately poured with dental stone. Geometric shape analysis and gingival zenith were evaluated on the study model, where various lines were drawn to identify the gingival zenith, its location, and its displacement in millimeters from the vertical bisected line. Results: It was found that the geometric shape of the upper anterior teeth was 22.2% square teeth, 61.1% oval teeth, and 16.7% triangular teeth. The position of the gingival zenith for all upper anterior teeth in relation to the vertical bisected line did not exceed 1 mm. Conclusion: The bidimensional analysis, geometric shape, and gingival zenith of the upper anterior teeth do not show a relationship (P > 0.05)
