Retrospective quality assurance audit of Lateral Cephalometric Radiographs at postgraduate teaching hospital

Abstract

Objective: The objective of our audit was to assess the quality of lateral cephalometric radiographs by investigating the percentage of lateral cephalometric radiographic images that satisfied the good quality standards.
 Methods: The standard-based retrospective audit was conducted at Riphah International University, Pakistan, from April to September 2018. The sample size was 50 radiographs that were randomly selected from the radiographs taken over one year. The radiographs were graded according to the standards set by the National Radiation Protection Board by two evaluators after the necessary calibration. Moreover, the percentages of images that met the criteria set by the Royal College of Surgeons of England were identified. The data analysis was carried out by the SPSS software version 23.
 Results: Out of the 50 radiographs, thirty-one were Grade-I, sixteen were Grade-II and three radiographs were Grade-III. Furthermore, out of the criteria set by Royal College, one criterion met the 100% standard that was correct head positioning. Less frequent errors were comprised of poor visibility of soft tissue structures (16%), teeth not properly occluded (14%), Incorrect positioning of labels (12%), Sella and Nasion not visible (8%). According to the results of the quality assurance audit, the radiographs fell short of the required standards.
 Conclusion: Quality assurance by periodic auditing is important to yield radiographs with maximum diagnostic value, minimal errors, and avoid unnecessary radiation exposure by repeat radiographs. Recommendations were made for the formulation and implementation of comprehensive radiation protection regulations, at all the Dental institutes of Pakistan.

Retrospective audit for quality assessment of root fillings performed by undergraduate dental students in clinics

“… 8 , 9 An audit of the obturation radiographs is an important tool for quality assurance and evaluation of students' performance in dental education. 12 , 13 The audit process involves the evaluation of the radiographs acquired during clinical practice, according to the established standard criteria. 14 Despite the significance of performing RCT during clinical training, data on the evaluation of technical quality of RCTs performed by clinical students in KSA is scant.…”

The Relationship of Facial Soft Tissue A’N’B Angle and Facial Hard Tissue ANB Angle in Determination of Skeletal Relations

“…Sharpness is an important factor that must be met on radiograph), Detail (the ability of radiographs to show differences from each anatomical part) 7 , Distortion (affected by improper placement and alignment of the film or X-ray angulation) 8 , Resolution (a measure of the ability to distinguish one object from another) 5 , and Brightness (the radiographic ability to increase brightness, usually related to processing, timer and Kvp exposure) 9 .…”

Avaliação da performance de dois softwares com inteligência artificial por meio das medidas geradas pela análise de Mcnamara em telerradiografia cefalométrica lateral

“…A telerradiografia cefalométrica lateral é um exame complementar utilizado para o diagnóstico e tratamento de discrepâncias esqueléticas, relações dentárias e de tecidos moles das estruturas faciais (Albarakati et al, 2012;Debelmas et al, 2019). A partir da introdução do cefalostato, por Broadbent, em 1931, foi possível a padronização do posicionamento da cabeça do paciente durante a execução da técnica radiográfica, em consequência disso, o exame tornou-se uma ferramenta essencial no planejamento ortodôntico e cirúrgico (Chien et al, 2009;Olmez et al, 2011;Livas et al, 2019;Khan et al, 2020;Meriç & Naoumova, 2020).…”
