The main goal of quality assurance programme is to consistently provide diagnostic information at the lowest possible cost, and at the least possible exposure of the patient to ionizing radiation. The study aims at evaluating the knowledge and practice of ray equipment among radiographers in Kano metropolis. The study design was prospective and cross sectional conducted among radiographers in the Kano metropolis from April 2019 to October 2019. Non-probability sampling meth used in the selection of the respondents. An ethical clearance to conduct the study was obtained from the Human Research and Ethics Committee of the Kano State Ministry of Health, and informed consent was obtained from every selected respondent. A s questionnaire was designed and used an instrument for data collection. The questionnaire was validated by experienced colleagues, using a pilot study the reliability was rested and the chronbach’s alpha reliability coefficient was found to be 0.7 one questionnaires were administered to the consented radiographers in Kano metropolis. The obtained data was analyzed using SPSS version 22.0. Out of the 41 (100%) administered questionnaires 36 (87%) were returned, and all the returned naires were properly filled. Only 3 (8.3%) known the meaning of quality assurance programme, only 12 (33.3%) know the components of quality assurance programme and only 6 (16.7%) know the frequency of computed radiography system average score for knowledge among radiographers in Kano metropolis is 44.9% and that of practice is 47.9%. The study concludes that radiographers in Kano metropolis have poor knowledge and pactice of quality assurance programme.

BACKGROUND: During the masticatory cycle, loads of different intensities and directions are received by the dental structures and/or implants, which can cause micromovements at the junction between the abutment and implant. OBJECTIVE: The objective of this in vitro study was to evaluate the behavior of three different implant connections subjected to different load values using a digital radiography system. Additionally, the torque values for removing the abutment screws were also measured and compared. METHODS: Ninety sets of implant and abutment (IA) were used, divided into three groups according to the type of connection (n = 30 per group): EH group, external hexagon type connection; IH group, internal hexagon connection; and, MT group, Morse taper connection. RESULTS: MT group showed the better vertical misfit behavior at the three intensity of load applied, in comparison with EH and IH groups. In the analysis of torque maintenance (detorque test), MT group showed higher values of detorque when compared with the measured values of EH and IH groups (p < 0.001). CONCLUSIONS: The IA sets of EH and IH groups showed a microgap in all levels of applied loads, unlike the MT group this event was not observed. In the detorque test, MT group increase in the torque values when compared to the initial torque applied, unlike EH and IH groups showed a decrease in the initially torque applied in all conditions tested. A positive correlation was detected between the misfit and detorque values.
