The distinctive "snake-eye" configuration of the pulp chamber is typically seen in the mandibular first premolar. This unique appearance is due to the anatomical features of the tooth's pulp chamber and canal system.

Key points to understand this feature:
- The mandibular first premolar often has two pulp horns representing the buccal and lingual cusps.
- On a radiographic or cross-sectional view, the pulp chamber appears as two small, round radiolucent areas resembling a pair of snake eyes.
- This configuration is less commonly observed in other teeth because they either have a single large pulp chamber or different canal anatomy.
- The maxillary first premolar may have two roots but does not exhibit the "snake-eye" appearance in its pulp chamber.
- The mandibular second molar and the maxillary canine have different pulp morphologies that do not correspond to this pattern.

Understanding this helps in endodontic diagnosis and treatment planning, as the presence of multiple canals can affect the approach to root canal therapy.
