Abstract
BACKGROUND & OBJECTIVE: Scaphoid fractures are the most common wrist fractures immobilization of wrist by plaster of Paris is the treatment of choice in persisting fractures of the middle and terminal part of the scaphoid. Many factors are effective on non:::union::: of scaphoid bone. The purpose of this study was to determine the relation between delay in starting treatment (1 to 3 weeks) with prevalence rate of fracture non:::union:::.
METHODS: In this study, the result of :::union::: in 57 patients with middle part fracture of the scaphoid and 1 to 3 weeks delay in treatment was compared with 60 patients as control who referred for treatment on the first day of fracture.
FINDINGS: Out of 57 cases under study, in 8 there was non:::union::: and in the control group, only 2 patients had non:::union:::, which indicated delay in treatment is significantly effective on nonn:::union::: of scaphoid fractures (p<0.05).
CONCLUSION: It is recommended that in case of feeling pain and sensitivity on the snuff box after trauma to wrist even when there is no evidence of fracture line in radiography be considered scaphoid fracture and treatment with plastering be undertaken and delay in starting treatment due to the increase in prevalence rate of scaphoid non:::union:::.

Abstract
Background and Objective: Cephalometric analyses are an important tool for diagnosis and orthodontic treatment planning. Some cephalometric analysis programs cannot be used due to the high cost and inability to use all the facilities due to the sanctions. CephNinja® is an available program for cephalometric analyses. The aim of this study is to evaluate the reliability and accuracy of the CephNinja® program for orthodontic cephalometric tracing and compare it with the common manual method in Iranian society.
Methods: This cross-sectional study included 100 lateral cephalometric radiographs prepared by the 3D Promax device; The patient's teeth were selected to be in maximum intercuspation and the patient's head was in natural head posture. In every 100 lateral cephalometric radiographs, 24 landmarks were identified and then 20 desired variables were measured by traditional manual method based on Steiner's analysis. Also, the digital file of the same 100 lateral cephalometric radiographs was entered into the CephNinja® software (version 3.51). Again, 24 landmarks were determined and then 20 desired variables were measured based on Steiner's analysis. The obtained data were entered into the software and compared.
Findings: The average ANB was 4.02±3.01 degrees in the traditional manual method and 3.08±4.04 degrees in the CephNinja® method. The average Wits was -1.12±3.90 mm in the traditional manual method and -1.13±4.16 mm in the CephNinja® method. The results show that there is no significant difference in the measurements of the two traditional manual methods and the CephNinja® software.
Conclusion: Based on the current study, it can be concluded that CephNinja® software is reliable and can be used similar to traditional manual method for cephalometric analysis in orthodontic patients.
