PATTERNS AND TIME OF PERMANENT TEETH ERUPTION IN THE GOMBE STATE CHILDREN AND ADOLESCENCES

Abstract

The study aims to determine the time, sequence, gender differences, and pattern of permanent
teeth eruption in Gombe State children and Adolescences. The total number of 300 individuals
with an equal number of males (n=150) and females (n=150) with ages ranges from 5-14 years
from Government day Secondary and Primary School Lijji were randomly selected for this
research. The data was collected with the subject sited on a chair under sunlight. The oral
examination was carried out using a mouth mirror, hand gloves, and a blunt probe. The teeth
were cleaned of food debris with cotton wool for proper visibility. The status of the eruption of
each permanent tooth was recorded even if a small part of the crown is visible clinically
penetrating the oral mucous membrane. It is regarded as erupted and recorded accordingly,
except for third molars. The obtained data were subjected to Student - t-test to obtain differences
in the pattern of permanent teeth eruption using SPSS version 20.0 software (IBM Corporation,
USA). The result shows that in the five years age group, none of the permanent teeth had erupted
in both males and females. In the age group of 14 years, all the permanent teeth except the third
molars had erupted, among which the maxillary teeth erupted earlier in males than females;
likewise the mandible teeth erupted earlier in males than in females.
