“…Scarfe et al found that this tool has limited value in the estimation of periapical lesions dimensions ( 35 ). Similarly, Pati et al found that it did not improve the accuracy of digital radiography ( 25 ). These findings may be reflected on the low usage of this tool among participants in the current study, as most of them (66.3%) either never used it (44.9%) or used it few-times (21.4%).…”

Objective: This study aimed at exploring the usage of radiographic image-enhancement tools in Saudi dental practice when interpreting radiographs taken for root-canal-treatments’ (RCTs) procedures and the influencing factors. Methods: An online survey including questions related mainly to the usage of images enhancement tools and the reasons for no or low frequently usage was constructed. The survey was sent to 550 general dentists (GDs), randomly selected from the Saudi Dental Register, and all endodontists (185) in Saudi Arabia using the Google-Drive tool. A reminder email was sent two months later to encourage none-respondents to complete the survey. Data were analyzed using the Chi-square and Linear-by-Linear Association tests at p=0.05. Results: While the highest percentage of GDs (48.3%) never used the colour-coded tool, the highest percentage of endodontists (46.1%) used it sometimes (P<0.001). The majority (84.2%) used the contrast tool either generally (67.8%) or sometimes (16.4%) (P<0.001); with more endodontists (77.55%) than GDs (63.1%) (P=0.011). As participants experience decreased and the weekly performed cases increased, the trend of using this tool increased (P<0.05). While most GDs (67.6%) either never (46%) or few-times (21.6%) used the highlight tool, most endodontists (56.9%) either used it generally (34.4%) or sometimes (22.5%) (P<0.001). The majority (82.3%) were using the magnification tool either generally (55.1%) or sometimes (27.2%). The highest percentage (36.1%) was generally using the negative-view tool (P=0.045); with more endodontists (63.7%) than GDs (20.8%) (P<0.001). While “I don’t know how to use it” was the dominant reason reported by GDs for not using most of the tools, lack of time was the dominant reason reported by endodontists (P≤0.001). Conclusion: The contrast and magnification were the most common used image-enhancement tools in Saudi dental practice. Endodontists reported greater preferences on using all images-enhancement tools than GDs. Unawareness and lack of time were the dominant reasons for not using the tools reported by GDs and endodontists, respectively. Further studies are required to determine the exact application for each tool and to investigate the impact of all image-enhancement tools on their diagnostic accuracy.

“…As a result, multiple angles can be taken to locate canals, determine root curvatures, verify working lengths, and intermediate obturation. In recent studies, however, digital radiography has not proven more accurate in diagnosing periapical lesions than conventional radiography, even after image processing and enhancement [4][5][6]. To overcome these shortcomings, new and more promising methods must be evaluated.…”

This study evaluates the efficacy of digital radiography and ultrasound (USG) for the distinction between periapical cysts and granulomas, determines the nature and extent of the periapical lesion, visualizes the lumen of the lesion, assesses its size, content, and vascularity. Material and MethodsThirty patients, ages 18 to 40, with well-defined periapical radiolucencies on maxillary or mandibular teeth, indicated for the extraction or periapical surgery, underwent digital radiography examination using the paralleling technique, followed by USG examination. A sonologist evaluated the lesions' size, echogenicity, and vascular content. The diagnosis was compared to histopathological examinations of tissues obtained through extraction or periapical surgery. ResultsThe diagnostic value of USG compared to the histopathological diagnosis of the periapical cyst was greater than that of the radiographic diagnosis, with an ultrasonographic diagnostic sensitivity (SN) value of 60% and a radiographic diagnostic SN value of 40%, respectively. The diagnostic value of USG imaging against the histopathological diagnosis of periapical granuloma was slightly lower than that of digital radiography, with an SN value of 72.2% for USG and 83.33% for digital radiography. However, the specificity (SP) value and precision of USG imaging were superior to those of digital radiographic diagnosis. USG imaging and radiographic diagnosis had 58.33% and 50% SP values, respectively. In cases of periapical abscess, the diagnostic values of USG against histopathological diagnosis were lower than those of radiographic diagnosis, which had an SN value of 100%. ConclusionUSG with color doppler is a more effective tool than digital radiography for diagnosing periapical lesions. The echo structure of the lesions and the presence of vascularity on USG with color doppler correlated with histopathology better than the radiological diagnosis.
