Background: To compare the maxillary sinus (MS) volumes of the patients’ with and without
posterior crossbite (PCB).
Method: The CBCT scans of 2 groups were studied: (1) 50 patients (mean age: 14.39±1.32
years)without posterior crossbite (NCB); (2) 24 patients (mean age: 14.15±1.53 years) with PCB.
After the volume calculation with using Dolphin 11.0 (Dolphin Imaging, Chatsworth, Calif,
USA) software, paired sample t test was used to compare the differences between the right and left
maxillary sinus volume of each group. Independent sample t test was used to identify the left, right
and mean maxillary sinus volume differences between groups.
There were 372 individuals included in the study, ranging from ages 12-79, who were divided into
seven groups according to age: 12-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79. CPITN values in
each group were included. In addition, the level of education, frequency of brushing, and the oral
appliances used in dental care were recorded.
Results: No significant differences were observed between right and left maxillary sinus volume for
each group (p> .05). Right, left and mean maxillary sinus volume calculated from PCB group was
found significantly lower than those calculated from NCB group (p< .01).
Conclusion: Right, left and mean MS volumes of PCB patients’ were significantly lower than NCB
individuals
