Objective: To determine correlation between tonsillar grade and transverse maxillary arch dimension.
Material and Methods: A cross sectional study of 50 patients was conducted at the department of Orthodontics Khyber College of Dentistry, Peshawar from July 2106 to December 2016 with age range from 5 to 12 years. The sample was selected through non-probability consecutive technique. They were divided into 5 subgroups according to their tonsil sizes. The different sizes were grouped into grades according to the standardized tonsillar hypertrophy grading scale of Brodsky and Koch. The transverse dimensions of maxillary arch which was measured were; intercanine width and intermolar width. Spearman rank test was applied to determine the correlation between tonsillar grade and transverse arch dimension using SPSS 20.
Results: The mean age in this study was 8.53±2.02 years. The most common grade was grade 1, n=26, (52%) followed by grade 2, n=13 (26%). The mean intercanine width was 30.7±0.803 mm and mean intermolar width was 35.8±1.01 mm. A negative correlation (r=-0.079) was found between age and tonsillar grades (0,1,2,3, and 4) which was statistically non-significant (p value=0.585). Similarly a negative correlation(r=-0.046) was found between intercanine and tonsillar grades (0,1,2,3, and 4) which was statistically significant (P value=0.049) while intermolar and tonsillar grades have negative correlation(r=-0.030) and the p value was non-significant(p=0.0838).
Conclusions: Maxillary intercanine and intermolar widths were significantly and negatively correlated tonsillar grade.
