Abstract
Background and Aim: The most concern about children with head and face trauma is the effects of the trauma and the treatment on their growth considering the possibility that the teeth in different stages of evolution that are adjacent to the fracture line, have different prognosis in growth and deformity. The present study examines the situation of the teeth around fracture lines in order to check the effects of the trauma on the mentioned teeth.
Methods and Materials: Complete information of 28 under 12 years old patients with jaw fracture that were admitted in the Bahonar hospital from 2010 until 2016, was extracted from files and Teeth adjacent to fracture line were clinically evaluated. Panoramic graphs that were taken instantly after the surgery and in the next 6 to 24 months period were inspected. The information examined in the panoramic graphs contained the level of internal and external erosion pathological lesion, and growth rate of teeth adjacent to the fracture line.
Ethical Considerations: This article was ethically approved by ethical committee of Kerman University of Medical Sciences (ethical code: IR.KMU.REC.1396.1398).
Result: 60/7 percent of the fractures were occurred in the lower jaw which in 67/9 percent of the times were treated by internal fixation and 10/7 were treated by Open Fracture Reduction. 89/3 percent of cases were free of pathological lesion. In 78/6 percent of cases change in color and in 71/4 percent of cases dental necrosis was not observed. 82/1 percent of the teeth had reached full growth.
Conclusion: Most of the teeth adjacent to the fracture line had reached full growth and lacked pathological, color change, root deformation and loose teeth problems and there was no Difference in Open Fracture Reduction and internal fixation.

Abstract
Introduction: The sinuosus canal and its branching accessory canals have crucial importance across different races for minimizing neurovascular problems in dental implantation.
Methods: This study was performed as a retrospective analysis, employing Cone beam computed tomography(CBCT) images of 174 patients who attended a private oral and maxillofacial radiology center in Arak from 2018 to 2020. The CBCT images were examined with Romexis software. Quantitative variables were reported as mean ± standard deviation, whereas qualitative variables were presented as frequency percentages. The data were analyzed using the independent T-test. The correlation between quantitative data was examined using Pearsons correlation coefficient and logistic regression analysis. One-way ANOVA was performed to analyze variables including age groups and the location of accessory canals.
Results: 65.5% of the participants had a canalis sinuosus, demonstrating a considerable prevalence of canalis sinuosus in the studied population. Age and gender did not significantly correlate with the prevalence of accessory and sinuosus canals (P > 0.05). However, a significant difference was observed in the mean diameter of the canalis sinuosus between males and females (P = 0.01). The most common location for the termination of accessory canals on the left side in females was posterior to the lateral incisor (48.3%), whereas in males, it was posterior to the central incisor (45.8%). On the right side, the most common place in females (45.5%) and males (36.4%) was also posterior to the central incisor.
Conclusions: The prevalence of sinuosus and accessory canals in different populations and races is more closely related to sample size and race and requires investigation across different races to reduce neurovascular complications.
