Abstract

Background: Monitoring of radiographic image quality is essential in any quality assurance programme. This audit aimed to investigate the clinical and processing quality of intra-oral periapical (IOPA) and bitewing (BW) radiographs taken at an outreach clinic. Aims: To audit the image quality of IOPAs and BWs taken at our dental outreach clinic. Standards: The acceptable standard aimed according to the NRBP and FGDP guidelines for all radiographs to reach was: Grade 1 >70% (Excellent), Grade 2 <20% (diagnostically acceptable) and Grade 3 <10% (Unacceptable). Methodology: A pilot study was performed on 10 IOPAs and 10 BWs for inter and intra-examiner reliability. 50 IOPAs and 50 BWs were reviewed in 2 audit cycles with an 8-month interval (total of 200 radiographs). Results: 1st cycle findings: Out of 52 IOPA 1(2%) scored grade 1, 47 (90%) scored grade 2 while 4 (8%) grade 3. Of the 51 BWs taken 4 (8%) scored grade 1, 43 (84%) scored grade 2 and 4 (8%) grade 3. 2nd cycle findings: Out of 25 IOPA 12 (48%) scored grade1, 11 (44%) scored grade 2 whereas only 2 (8%) were grade3. For BWs 14 (55%) were grade 1, 11 (45%) grade 2 whereas none of the BW was graded as grade3. A distinct improvement was observed in the radiograph quality between both the cycles, however the standards still fell short of the guidelines. Action plan and future recommendations: Action plan and future recommendations: Practical training and lectures were arranged. Recommendations made to improve the radiograph quality included use of paediatric film sizes, collimator alignment and use of phosphor plates in good physical condition. Conclusion: Substantial improvement was seen in the 2nd cycle. However, the overall standard was still not met. Therefore, continuous staff education along with continuing the audit spiral will help reach the gold standards.
