In the present study, the prevalence of other anomalies (odontoma, fusion, dens invaginatus, talon cusp, taurodontism, macrodontia, dilaceration, ectopic eruption
and microdontia) were observed more rare than other prevalence studies (4,7,10,17).
This leads to an increased possibility of the ectopic eruption
of maxillary canines.
of maxillary canines can lead to root resorption on maxillary lateral incisors especially on apical and middle thirds of the roots.
Early loss of primary teeth causes many problems including ectopic eruption
of permanent teeth, space loss of successors, bad esthetics, speech skill, low self-esteem and poor social interaction.

Weinberger S, Wright G: The unpredictability of primary molar resorption following ectopic eruption
of permanent molars.
Moderately ankylosed mandibular primary molars are observed with mild incisor crowding and radiographic evidence of ectopic eruption
of second premolars and available leeway space (Figure 6a).
The impaction of first molars is often diagnosed as ectopic eruption
, whereas impaction of second molars is usually associated with arch-length deficiency (Raghoebar et al.
Patients' dental records and radiographs were examined in order to detect the dental anomalies: congenitally missing teeth, impactions, ectopic eruption
, supernumerary teeth, dilacerations, microdontia, and any other unusual finding that can be assessed with OPG.

and alteration of tooth morphology.
