Image quality assessment of pre-processed and post-processed digital panoramic radiographs in paediatric patients with mixed dentition

Abstract

PurposeTo determine the impact of an image processing technique on diagnostic accuracy of digital panoramic radiographs for the assessment of anatomical structures in paediatric patients with mixed dentition.Materials and MethodsThe study consisted of 50 digital panoramic radiographs of children aged from 6 to 12 years, which were later on processed using a dedicated image processing method. A modified clinical image quality evaluation chart was used to evaluate the diagnostic accuracy of anatomical structures in maxillary and mandibular anterior and maxillary premolar region of processed images.ResultsA statistically significant difference was observed between pre and post-processed evaluation of anatomical structures (P<0.05) in the maxillary and mandibular anterior region. The anterior region was found to be more accurate in post-processed images. No significant difference was observed in the maxillary premolar region (P>0.05). The Inter-observer and intra-observer reliability of both pre and post processed images were excellent (>0.82) for anterior region and good (>0.63) for premolar region.ConclusionThe application of image processing technique in digital panoramic radiography can be considered a reliable method for improving the quality of anatomical structures in paediatric patients with mixed dentition.

Comparison of radiograph panoramic quality between conventional and indirect digital methods on mixed teeth period

“…Another factor that may affect the quality of the panoramic radiograph image is the quality of x-ray equipment. 5,17 Radiographic capabilities may be a factor that may affect the quality of the panoramic radiograph image. 18 Panoramic radiographs of mixed tooth periods can be used to assist dentists in diagnosing childhood disorders.…”

Image quality evaluation method for surface crack detection based on standard test chart

“…In this regard, various international standards have been established for evaluating image quality using general image acquisition equipment. For instance, the International Organization for Standardization (ISO) 12233 test chart and the corresponding Camera and Imaging Products Association (CIPA) DC‐003 image resolution test method have been widely used (Gharehaghaji et al., 2019; Suryani et al., 2018). These international standards have specific guiding significance for testing the imaging effect of structural inspection equipment.…”

“…1 Ketajaman gambar pada radiograf panoramik dibutuhkan saat mendeteksi lesi karies, observasi perkembangan gigi-geligi dan kondisi patologis di rongga mulut. 2 Kualitas gambar radiograf panoramik salah satunya dipengaruhi oleh ketajaman, sehingga penilaian ketajaman dapat digunakan untuk mengevaluasi kualitas gambar secara efektif. 3 Kualitas gambar radiograf panoramik dengan nilai diagnosis baik akan memberikan informasi dan gambar lengkap.…”

“…6 Tidak tajam dan buramnya gambaran radiograf menyebabkan diagnosis serta rencana perawatan menjadi kurang tepat, lesi karies tidak teridentifikasi dengan baik, menyulitkan observasi perkembangan gigi-geligi dan menyebabkan pasien terekspos radiasi berlebih, karena dibutuhkan pengulangan pengambilan gambar radiograf. 8,9,12 Penelitian tentang ketajaman radiograf telah dilakukan di berbagai kota dan negara. Penilaian ketajaman radiografi di Universitas Jambi telah dilakukan menggunakan phantom berupa air dalam wadah plastik sebagai pengganti rahang manusia.…”
