Abstract EN
The aims of the study were to determine the time and sequence of eruption of permanent teeth.
Also to determine the differences in timing of tooth emergence according to side, jaw and gender variation.
Timing and sequence of eruption were studied cross–sectionally in a group of (2391) children and teenagers from Mosul City, Iraq : (1296) males and (1095) females ranging age from (4–16) years.
The data were statistically analysed using Karber’s analysis in order to compute the mean and standard deviation of emergence.
The results showed that there are no statistical differences between the mean time of corresponding right and left teeth in both genders.
The finding of the study demonstrated that the mandibular teeth emerge before their maxillary opposing teeth in both genders with the exception of the premolars where the order is reversed.
The results also demonstrated that the females have their permanent teeth to emerge earlier than those of males.
The differences between the two genders are clearly seen in the eruption of mandibular canine.
The females acquired all their permanent teeth to emerge in shorter time span than males (difference 1.8 months).
A specific sequence of permanent teeth emergence was found in both arches and for each gender.
In general, the emergence of permanent teeth starts with the emergence of mandibular first molar and ended with the maxillary second molar.
