The author has observed the ectopic eruption pattern on oblique cephalogram of 195
children.(5 years: 78, 6 years: 58, 7 years: 59)
The results were as follows;
1) Making a comparison between hold type and jump type of ectopic eruption, there
are 4 cases in Hold type, 5 cases in jump type.
2) Making a comparison of ectopic eruption between male and female, there are 7
cases in males 2 cases in female.
3) Making a comparison of ectopic eruption between right side and left side, there are
5 cases at right side, 4 cases at left side.
4) Making a comparison of ectopic eruption among 5 years to 7 years, there are 4
cases in 5years, 3 cases in 6 years, 2 cases in 7 years.
5) The prevalence of ectopic eruption of the maxillary first molar was 4.61%.
6) Normal eruption angle of the maxillary first molar is prevailing in 80¡Æ¡85¡Æ.
