Summary
This study found significant differences in the gingival zenith position (GZP) between males and females for lateral incisors, aiding in periodontal surgery and esthetic dental procedures.
Area of Science:
- Dentistry
- Periodontology
- Esthetic Dentistry
Background:
- The size, proportion, and gingival zenith position (GZP) of maxillary anterior teeth are crucial for anterior esthetics.
- Understanding sex-based differences in GZP and gingival zenith level (GZL) can inform esthetic dental treatments.
Purpose of the Study:
- To compare the GZP and GZL between males and females on the right and left sides of the maxillary arch.
- To establish esthetic parameters for anterior teeth based on GZP and GZL.
Main Methods:
- Dental casts of the maxillary arch were created using irreversible hydrocolloid and dental stone.
- Gingival zenith position (GZP) was measured from the midline along the tooth's long axis.
- Gingival zenith level (GZL) of lateral incisors was measured relative to the adjacent teeth's gingival line.
Main Results:
- Significant differences in GZP were observed between males and females for lateral incisors.
- Significant differences in GZP were also found between the right and left sides for lateral incisors.
- No significant difference in GZL was found between males and females for lateral incisors.
Conclusions:
- The established GZP and GZL values provide clinical guidelines for periodontal surgery, crown lengthening, and root coverage procedures.
- These parameters are valuable for reestablishing the GZP of maxillary anterior teeth to improve esthetics.

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
