Ectopic eruption of the first permanent molar occurs due to the abnormal mesioangular eruption path of the molar resulting in an impaction at the distal prominence of the primary second molar’s crown. It can be suspected if asymmetric eruption is observed or if the mesial marginal ridge is noted to be under the distal prominence of the second primary molar. Ectopic eruption can be diagnosed from bitewings or panoramic radiographs, Fig 1, 2. The prevalence of this condition is reported to be up to 0.75%1. The ectopic eruption is more common in cleft lip and palate patients1.
