This document discusses various developmental disturbances that can affect the jaws, teeth, tongue, lips, palate, and gingiva. It identifies and describes disturbances including micrognathia, macrognathia, peg lateral, gemination, fusion, concresence, dens invaginatus, hypodontia, cleft lip and palate, ankyloglossia, benign migratory glossitis, Fordyce's spots, and elephantiases gingivae. It provides images and describes the clinical presentations and complications of each disturbance.
