Assessment Of Sox2 Expression As A Tumor Stem Cell Marker In Ameloblastoma And Dentigerous Cyst, Haneen Mahmoud Zeen El-Abdeen, Noha Ahmed Mansour, Sherif Yousef Elnagdy, Mohamed Abdel-Monem Tawfik

Mansoura Journal of Dentistry

Objective: The pathogenesis of odontogenic lesions remains unclear; however, a probable explanation could mean the presence of tumor stem cells (TSCs). The preservation of stem cells during early dental development is governed by many transcription factors, including sex-determining region Y (SRY)-box 2 (SOX-2). Numerous studies observed the increased expression of SOX2 in various benign and malignant tumors as its impact on tumorigenesis varies according to tumor type. This research aims to determine the predictive importance of the SOX2 stem cell marker by evaluating its immunoexpression in ameloblastoma (Ab) and dentigerous cyst (DC). Materials and Methods: Twenty-Four samples were part of …

Mansoura Journal of Dentistry

Objective: To assess the root canal anatomy and root morphology of mandibular third molars (MTMs) in the Egyptians using cone beam computed tomography (CBCT). Methods: A total of 338 CBCT scans of mandibular third molars (MTMs) were collected and evaluated regarding the related root(s) number and root canal configuration. Statistical analysis highlighted differences between different categories and their prevalence among genders and sides (significance level was set at p < 0.05). Data were presented as frequency and percentage values and were analyzed using a chisquare test followed by pairwise comparisons utilizing multiple Fisher’s exact tests with Bonferroni correction. The significance level was set at p < 0.05 within all tests. Results: A total of 338 MTMs [186 (55%) from male patients, 152 (45%) from female patients] from 279 patients (151 male and 128 female) were evaluated. The majority (82.84%) of the studied MTMs had two roots. single-, triple-, and quadruple-rooted MTMs were less common than double-rooted MTMs, accounting for 10.1%, 5.33%, and 1.18% of the sample, respectively. Regarding root canal anatomy, Vertucci type I was the most seen morphology (61% of all MTMs roots mostly in distal roots (42.41%), followed by Vertucci type III (13.08%). The chi-square test showed no significant difference between males and females (p=0.36) or between the right side and left sides (p=0.691) regarding the number of roots. Conclusion: Within the limitations of the present study, the findings conclude significant variability in the root and root canal anatomy of mandibular third molars (MTMs) within the Egyptian sub-population.
