Emergence angles in natural anterior teeth: influence on periodontal status.

Objectives: To find the geometric values of emergence angles in human natural anterior teeth and to study their influence on periodontal status.

Method And Materials: Fifty anterior teeth with full-crown restorations and homologous contralateral sound teeth were examined for clinical parameters: Plaque Index, Gingival Index, probing depth, and clinical attachment loss. Impressions and stone casts were made and then separated along the midline of the teeth.
