technical errors

Success in endodontic treatment is directly related to proper diagnosis and neutralization of microorganisms using mechanical and chemical methods and full canal obturation. Given that technical errors can affect the success of treatment and cone beame CT can detect these errors perfectly, the aim of this study was to determine the frequency of technical errors in root canal treatment using CBCT

In this descriptive-analytical study, 1067 endodontically treated roots in CBCT stereotypes were investigated. Fine-grained diagnostic radiographies were investigated in coronal, sagittal and axial planes. Filling length errors (tip to tip obturation, underfilling, overfilling, voide), errors during preparation (perforations, transport, broken instruments, missed canal and vertical root fracture) were recorded. The data were analyzed by Chi-square and Fisher's exact test

Moreover, the highest technical errors occurred were transport (23.8%), overfilling (21.2%), underfilling (21.1%) and voide (17.8%) and the lowest technical error occurred was zipping (0.3%). The highest technical errors occurred in the anterior regions including single canal teeth (18.7%) and single canal premolar (11.4%) and the lowest technical errors were found in the buccal and lingual canal of double canal canines (4 %). The frequency of radiographic lesions (p = 0.005) and the expansion of PDL (p <0.001) were significantly different between different dental areas; however, the frequency of resorption was not significantly different between different dental areas (p = 0.11).

The highest observed error was in the anterior area of a canal and the lowest error rate determined by the CBCT was related to the two canal canine (buccal) and two canal canine (lingual). transport, short-term filling, and void were the most endodontic errors and the lowest ones were related to zipping cousing with broken file and post perforation  in the root canal treatment.

Errors in the Health and Medical Systems has multi-dimensional parameters. Human parameters, system, equipment are the error making factors and by managing these parameters such errors can be reduced. The aim of this study was to survey the path of information and errors within the HIS system. T his study was based on analytic al method in which the hospital information system of Urmia Imam Khomeini Medical Education center were analyzed; in doing so the technical errors also the human errors in the path of information from deferens parts of the hospital in the HIS system were found using a prepared che c klist. Finely t he algorithm of errors or in other words the path in which there was a high technical and human error were reported. According to t he finding s there wa s a great gap between the human errors and the education level of operators (p =0/000). In contrast there was a signatures difference between the human errors and different working times (p >0/05). Also there was no significant difference between the human errors and various parts of the hospital working with HIS (P<0/05). By analyzing the path of information in the system of HIS, it was seen that maximum error occurs in the time shifts of nights and holidays and the clinical wards up to 40% and 33.33%, Respectively. By paying attention to the changes in the needs of the h ealth area as time goes on, the information system should adapt itself to the changes; these changes should be in parallel with the changes in the structure and the missions so that it would fulfill the needs of operators and prevent errors.

Today the quality of health service is determined by providing the service by appropriate operators (people)، within the shortest time and with minimum resonances. The aim of the study is to find the path of information and the errors in Hospital information system.

this study is done by the analytics method in which the hospital information system of Urmia Shahid Motahari Education center was analyzed، in doing so the technical errors also the human errors in the path of information from deferens parts of the hospital in the HIS system were found by using a prepared cheek list. Finely t he algorithm of errors or in other words، the path in which there was a high technical and human error were reported.

the finding show us that there is a great gap between the human errors and the education level of operators (P=0/000). In contrast there was a signatures difference between the human errors and different working times (P>0/05). Also there wasn’t a significant difference between the human errors and various parts of the hospital working with HIS (P<0/05). By analyzing the path of information in the system of HIS it was seen that maximum error occurs in the time shifts of nights and Holidays.

By paying attention to the changes in the needs of the Health area as time goes on، the information system should adapt itself to the changes also these changes should be in parallel with the changes in the structure and the missions so that it would fulfill the needs of operators and prevent errors.
