palatine tonsil size, occlusion


Background and objectives: The effect of the palatine tonsil size in the development of
dental intra-arch and inter-arch abnormalities is often brought up in the literature, but it
remains controversial. Data on the possibility of a relationship between enlarged tonsils
and the occurrence of malocclusions are subjective. The purpose of this study was to seek
an association between the space occupied by the palatine tonsils and the dental arch
Methods: A cross-sectional study was performed in Erbil city on a group of primary school
students aged (10-12) years old. A tonsillar examination was performed for each student
and graded according to the standardized tonsillar hypertrophy grading scale. A sample size
of (300) students, (160) male and (140) female was randomly selected. Dental impressions
were taken for each student. Data were analyzed with SPSS program version 22. Comparisons of qualitative variables according to tonsillar grade and gender and the relation of
tonsillar grade according to gender were made using the chi-square test. The strength of
the association between tonsillar grade and qualitative variables was evaluated with a phi
coefficient (φ). The strength of the association between tonsillar grade and quantitative
variables was assessed by Spearman's rank correlation coefficient (rho). The association
between gender and quantitative variables was evaluated by t-test. The significance
threshold was set at P ≤ 0.05.
Results: Results showed that there was a significant and positive relation between Angle's
molar relationship, overjet, and palatine tonsil size but no significant difference in palatine
tonsil size according to males and females.
Conclusions: Early evaluation of the size of the palatine tonsils by the pedodontist would
help prevent orthodontic abnormalities caused by upper airway obstruction during childhood.
