To date neither the eruption mechanism nor the factors controlling eruption have been completely understood. Primary retention of permanent teeth is an isolated condition associated with a localized failure of eruption with no other identifiable local or systemic involvement. Multiple primary retention may be related to lack of eruptive force, rotation of tooth buds, syndromes and metabolic disorders. This article reports an unusual case of primary retention of permanent teeth inclusion in a 21-year-old woman with hyperthyroidism, diagnosed at 14 years of age.
