Abstract
Introduction: The maxillary sinus is of great interest with its intricate relationship to the Oro maxillofacial structures, serving as a narrative investigative tool for age and gender estimation in forensic dentistry. Numerous software programs are utilized in medical surgeries to analyse and print reconstructive organs. Among these, ITK-SNAP and MIMICS are particularly useful for volumetric estimation of sinuses using cone beam computed tomography scans. Aim: The aim of this study is to evaluate maxillary sinus volumes using CBCT scans and compare the analysis provided by two different software programs, ITK-SNAP and MIMICS, in terms of age-gender estimation. Materials and Methods: This study was performed in 154 patients selected by a retrospective review of the archives of the Vishnu dental college, Department of Oral Radiology. Patients were divided into five age groups (18–24 years, 25–34 years, 35–44 years, 45 years) and by sex. Cone-beam computed tomography (CBCT) images of the patients were transferred to the MIMICS & ITK-SNAP software and the Maxillary Sinus Volume (MSV) was measured. All statistical analyses were performed using the SPSS (Statistical Package for Social Sciences, version 21) software. Results: There was no statistically significant difference between the right and left maxillary sinus volume according to the findings obtained from our study, and maxillary sinus volume in males was found to be significantly higher than that of females. Another finding of our study is that the maxillary sinus volume decreases with age increase. Especially it was also found that the sinus volume in males in the 18–24 age group was statistically significantly. A strong positive Pearson correlation coefficient of .798 was obtained between “MIMICS” and “ITK-SNAP” for maxillary sinus volume, which is highly statistically significant (p-value = .000). This indicates a robust positive linear relationship between the maxillary sinus volumes obtained through “MIMICS” and “ITK-SNAP” methods. Conclusion: Consequently, maxillary sinus volume measurements can be made on CBCT scans using reconstruction software. For measuring and segmenting, the ITK-SNAP program is suggested since it provides a dependable and easy-to- use semiautomatic approach that made the study’s findings possible.
