What is the incidence of permanent ectopic molar eruption?

The incidence of permanent ectopic molar eruption is most accurately represented by the percentage range of 2-3%. Permanent molars, particularly the first molars, can often have issues with their eruption path due to various factors such as the position of the adjacent teeth, crowding, or anatomical variations in the dental arch. The 2-3% incidence rate reflects clinical observations and research findings, indicating that while ectopic eruption is not extremely common, it is a notable concern that dental professionals must monitor.

The percentages provided in the other choices imply higher frequencies, which do not align with the documented occurrence of ectopic eruptions. The understanding of this specific incidence helps dental professionals anticipate potential challenges in molar eruption during orthodontic evaluations and pediatric dentistry, ensuring that appropriate interventions can be planned if necessary.
