The size, proportion and gingival zenith position of maxillary anterior teeth plays in
the anterior teeth esthetics.
To compare the gingival zenith positions and levels between male and female in right
and left side as an esthetic parameter.
Impression of the maxillary arch was made in each participant with irreversible
hydrocolloid, and dental cast was made with dental stone type IV. Two clinical
parameters were evaluated: (1) the gingival zenith position (GZP) from the vertical
bisected midline along the long axis of each individual maxillary anterior tooth;
and (2) the gingival zenith level (GZL) of the lateral incisors in an apical-coronal
direction relative to the gingival line joining the tangents of the GZP of the adjacent
central incisor and canine teeth under healthy conditions. Statistical analyses were
conducted using SPSS with the level of significance (α) = 0.05. Descriptive statistics
was done and Independent t-test was used to compare the GZP and GZL between
male and female.
In male, the gingival zenith position for right side central, lateral and canine were
1.05 mm, 0.57 mm and 0.14 mm, and in left side were 1.02 mm, 0.53 mm, 0.15 mm.
In female, the gingival zenith position for right side central, lateral and canine were
0.99 mm, 0.48 mm and 0.15 mm, and in left side were 0.94 mm, 0.44 mm and 0.14
mm. The gingival zenith position was significantly different between male and female
for both lateral incisors. In addition, significantly different was found for the lateral
incisor between right and left side. In male, the gingival zenith level of right and left
lateral incisors 0.74 mm and 0.71 mm. In female, the gingival zenith level of right
and left lateral incisors 0.76 mm and 0.72 mm. No significant difference was found
between male and female for the gingival zenith level of right and left lateral incisors.
The GZP and GZL obtained from this study can be clinically applied to reestablish the
GZP of the maxillary anterior teeth during periodontal surgery; crown lengthening or
root coverage procedures.Keyword :
