Abstract
ABSTRACT
Background
Primary teeth emergence is an important milestone in children and timing of
emergence varies among populations.
Objective
To determine the emergence time and sequence of primary teeth in a sample of
Nepalese children visiting Dhulikhel Hospital.
Method
A descriptive cross-sectional study was conducted in children of 5 months to 4 years
visiting Dhulikhel Hospital. The emergence of incisal tip to incisal margin for incisors
and canines, cusp tip to occlusal margin of molars visible were recorded along with
age in months and gender. Descriptive statistics was done to calculate the mean age
of emergence of each tooth with standard deviation. Unpaired t-test was used to
assess the difference between the mean age of emergence of teeth between right
and left sides and between boys and girls.
Result
The first teeth to emerge was mandibular central incisor at the age of 9.37 ± 1.42
months and the last one was maxillary second molar at the age of 32.91 ± 6.39
months. There was no significant difference in the mean emergence time between
the maxillary and mandibular jaws, between right and left sides of jaws and between
boys and girls except for primary maxillary right central incisor and mandibular right
second molar which was found to be emerged early in girls.
Conclusion
The emergence time and sequence of primary teeth observed in the present study
can be used as a baseline data for the children of Kavre district.
