Summary
The surface area of the gingival embrasure (SRE) is a more accurate radiographic predictor of black triangles (BTs) than linear measurements. Patient age was also found to be significantly associated with BT occurrence.
Area of Science:
- Dentistry
- Radiology
- Periodontology
Background:
- Black triangles (BTs) are a common aesthetic concern.
- Predicting BTs is crucial for treatment planning.
- Current radiographic methods have limitations.
Purpose of the Study:
- To compare the diagnostic accuracy of gingival embrasure surface area (SRE) with linear measurements (CBC and IHD) for predicting BTs.
- To explore patient-related factors and gingival phenotype associated with BT occurrence.
Main Methods:
- Retrospective analysis of 118 interdental papillae from 35 patients.
- Utilized cone beam computed tomography and clinical photographs.
- Employed ROC curves and logistic regression for analysis.
Main Results:
- SRE showed superior diagnostic accuracy (AUC=0.98) compared to CBC (AUC=0.89) and IHD (AUC=0.63).
- Optimal SRE threshold was 5.04 mm² with high sensitivity and specificity.
- Increased patient age was significantly associated with BT presence (OR=1.18).
Conclusions:
- SRE is a more accurate radiographic indicator for predicting BTs than linear distances.
- Patient age is a significant factor associated with BT occurrence.
- SRE offers a valuable alternative for clinical prediction of BTs.
