title: Morphological measurements of anatomic landmarks in pulp chambers of human anterior teeth.
abstract: This in vitro study measured key morphological features of pulp chambers in anterior teeth and tested the hypothesis that the distance from the lingual surface (midpoint from the cusp tip to the lingual CEJ) to the pulp chamber (the midpoint from the buccal to the lingual CEJ) was similar for different tooth types. Extracted human teeth were sorted and 100 samples of each of the following tooth types were chosen: maxillary central incisor (UCI), lateral incisor (ULI), and canine (UC), as well as mandibular central incisor (LCI), lateral incisor (LLI), and canine (LC). All teeth were digitally radiographed on a 1-mm X-ray grid. The mean values of measurement C, the distance from the lingual surface to the pulp chamber, varied significantly between tooth types (p<0.001). The mean values and SNK rankings were as follows: LC (5.9+/-0.5 mm)>UC (5.5+/-0.5)=UCI (5.4+/-0.4)>ULI (5.0+/-0.4)>LLI (4.8+/-0.5)>LCI (4.4+/-0.4).
