Resumen
Objective: Estimate the DGC dimensions and determine whether the DGC
dimension varies by gingival biotype.
Methods: A cross-sectional study was performed in the Undergraduate and
Prosthodontic Graduate Program clinics of the School of Dental Medicine, University
of Puerto Rico from August 2011 to April 2012. A total of 53 participants who
needed restorative crowns in their teeth were recruited. Prior to crown preparation,
the gingiva was classified as having a thin, mixed or thick biotype, according to
transparency, using a standardized 15 UNC Hu-Friedy® periodontal probe. The DGC
dimension was measured by transulcus probing. Descriptive statistics were calculated
in mesial, medial, and distal sites by phenotypes. Differences between and within
the sites’ DGC dimension mean were determined using a Friedman test. The level
of significance was 0.05.
Results: Mean DGC dimensions, in millimeters, for all sites measured were: 3.09
(95% CI: 2.91-3.27), 3.40 (95% CI: 3.18-3.62), 2.70 (95% CI: 2.51-2.89), and 3.17 (95%
CI: 2.94-3.41) in mesial, medial, and distal sites, respectively. In thick, mixed, and
thin biotypes the mesial sites showed greater DGC dimension means than the medial
and distal (p<0.05) sites. Mean DGC dimension was greater for the thin compared to
mixed and thick biotypes at mesial, medial and distal sites (p<0.001). Nevertheless,
the thick biotype presented the smallest DGC mean dimensions compared to mixed
and thin biotypes at the same sites.
Conclusion: The DGC dimensions in all sites were similar to those reported in the
literature. DGC dimensions are different for thin, mixed and thick gingival biotypes.
