deciduous teeth

The clinical image clearly depicts fusion between two deciduous maxillary incisors, evidenced by the visible groove running vertically along the crown, indicating the junction where two separate dental entities have united during development. This developmental dental anomaly occurs during the morphodifferentiation stage of tooth development when two normally separated tooth buds develop too close to each other, leading to contact and subsequent fusion of dental hard tissues.

This image depicts the bottom teeth of a seven-year-old child showing the natural progression from primary (deciduous) teeth to permanent dentition. The photograph clearly illustrates three distinct stages occurring simultaneously: primary teeth still in position, a vacant space where a primary tooth has been naturally exfoliated, and an emerging permanent tooth.
