“…The distance between two image locations that may still discriminate or be seen is called the spatial resolution. While the radiographic picture contrast is determined by the relative difference in optical density between two adjacent portions of the film, noise is anything that obstructs the image [10].…”

Several image enhancement applications can be used to increase SNR and brightness. However, if the setting of tube current-time is too high, the application can not reduce the radiation dose. So, It is necessary to test tube current-time variations on the SNR value and image quality to determine the effect on body organs and radiation dose. This study aims to determine the influence of tube current-time on SNR and with this research is expected to be an input for radiographers in the field to pay attention to parameter settings for patients. We compared five tube current-time variations on the Antebrachii examination by using Phantom (58 kV, 32 mA, 50 mSec), (58 kV, 100 mA, 50 mSec), (58 kV, 32 mA, 5 mAs), (58 kV , 32 mA, 5 mAs) and (58kV, 100 mA, 5 mAs). Then we made a circle of ROI with a diameter of 0.2 cm2 on the Bone, Soft-tissue and Air sections in that four tube current-time variations, each of which has 7 ROI points tocalculate the SNR and the radiation dose is seen from the image. There is a difference in SNR on tube current-time changes and affects the image quality with an Adjusted R square value of 0.003 and 0.865. It shows that there is a change in tube current that affects the Signal to Noise Ratio between organs. Since it is proven that changes in tube current-time affect image quality, further research can formulate an ideal parameter for the examination of each organ.

This research aims to map the processes existing in a dental clinic. For such, field research procedures were adopted, which were performed at a union dental clinic located in São Paulo-SP city. The data collect was made through non-participant observation and focused (semi-structured) interview. The processes of the clinic were modeled with the aid of MS-Visio Professional 2013 software, in order to clarify the usefulness and participation of each component of the process. The flowcharts built in the research were validated with the technical coordinator of the clinic, who corrected their inconsistencies with the reality in the clinic. After that, the flowcharts were validated with an expert in management. The results make possible to understand the usefulness of each process and identify both the hierarchy of the processes and the key processes; and provide a basis for decision-making. Considering the business model of the clinic, the analysis of the results pointed out an opportunity of increasing the number of patients seen at the clinic. Process mapping provides a better understanding of the routines of the clinic as well as of their steps, and it may help managers to determine their processes and focus on them. So, it understands here that process management is applicable in dental clinics starting from process mapping.

BACKGROUND: For placement of intraradicular posts the intracanal filling material has to be removed. If drills are employed for this purpose, extra widening of the canal, incomplete cracks or root perforation are probable when inappropriate size of drill is used. OBJECTIVE: This in vitro study assessed the efficacy of radiographs taken after completion of root canal therapy in selecting the appropriate-sized Peeso reamer for post space preparation. METHODS: Canals of 53 extracted maxillary and mandibular teeth of different types were cleaned and shaped. Then with acrylic resin 3-dimensional model of the intracanal space of each tooth was fabricated. Next, all canals were filled with gutta-percha and teeth were radiographed buccolingually. Based on these radiographs two observers selected a Peeso reamer that best matched each canal’s diameter. The diameter of the selected Peeso reamer was compared to the diameter of the corresponding resin model of each canal by two independent observers and the difference was measured. The data were analyzed by paired sample t-test using SPSS version 22. RESULTS: The diameter of the selected Peeso reamers ranged from 0.21 mm smaller to 0.12 mm larger than the diameter of intracanal spaces. The difference between reamer and resin model was less than 0.1 mm in 75% of the cases. CONCLUSION: The result of this study suggests that post-operation endodontic radiographs are reliable means for selecting a size of Peeso reamer that does not encroach on dentinal wall during removal of intracanal filling material and post space preparation.
