Summary
This summary is machine-generated.

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.
