The dimensions of the human dentogingival junction
Summary
The connective tissue attachment in the dentogingival junction shows variable width, unlike epithelial attachment, sulcus depth, or loss of attachment. This finding impacts understanding periodontal health and attachment levels.
Area of Science:
- Periodontology
- Oral Anatomy
- Histomorphometry
Background:
- The dentogingival junction is crucial for periodontal health.
- Understanding its natural dimensions is key to diagnosing and treating periodontal disease.
- Previous studies have varied in their focus on specific attachment components.
Purpose of the Study:
- To histomorphometrically examine the naturally occurring dimensions of the dentogingival junction in adult human cadaver jaws.
- To compare the variability of connective tissue attachment, epithelial attachment, sulcus depth, and loss of attachment.
Main Methods:
- Analysis of 10 adult human cadaver jaws.
- Histomorphometric measurement of 171 tooth surfaces.
- Quantification of connective tissue attachment, epithelial attachment, sulcus depth, and loss of attachment.
Main Results:
- Mean sulcus depth: 1.34 ± 0.84 mm.
- Mean epithelial attachment: 1.14 ± 0.49 mm.
- Mean connective tissue attachment: 0.77 ± 0.32 mm.
- Mean loss of attachment: 2.92 ± 1.69 mm.
- Connective tissue attachment exhibited a narrower distribution and range compared to other measured dimensions.
Conclusions:
- The connective tissue attachment width is more variable than previously suggested.
- Loss of attachment level does not predict connective tissue attachment length.
- Findings provide a baseline for understanding normal dentogingival junction dimensions.
