Congenital ichthyosis features a tooth anomaly of which type?

Root development can be disrupted in conditions that affect ectodermal derivatives, and in congenital ichthyosis the anomaly most often described is a bend in the developing tooth root called dilaceration. Dilaceration is a sharp angulation of the root (or crown-to-root axis) that occurs when the Hertwig’s epithelial root sheath formation is disturbed during development or is subjected to abnormal forces. This pattern fits ichthyosis-related disturbances better than the other options, which describe size changes (microdontia), enamel defects (enamel hypoplasia), or absence of teeth (hypodontia) but are not the characteristic dental finding linked to this condition.
