“…Inter-observer variation in radiological diagnosis is a well-recognised and important aspect of clinical dentistry. [14][15][16][17][18] Nevertheless, there was a clear tendency for the expert assessment to identify greater numbers of patients with abnormality, with the exception of periodontal bone loss. Furthermore, percentage agreement in identification of caries was particularly low (37.1%).…”

“…These observers had graduated from different dental schools with different experience backgrounds but had adequate preliminary radiographic education and training. Many studies 3,4,12,22,23 have previously reported using clinicians with a varying range of clinical experience, as with the current study. It was well documented by many authors that observer experience may influence the radiographic interpretation of early periapical pathosis 5,20,24,25 .…”

“…The radiographic examination allows the clinician to visualise the early indicators of periapical periodontitis, such as the loss of the lamina dura and widening of the periodontal ligament space 1 . However a number of studies have highlighted the fact that participating clinicians often show inconsistency in their ability to recognise these radiological signs which portent the presence of early inflammatory apical pathology [2][3][4][5] . Several research studies have been conducted in this field 6 .…”

Objectives:To investigate the ability of endodontists and general dental practitioners (GDPs) to interpret early periapical pathology and to examine effect of age, undergraduate education and attendance at courses upon radiographic interpretation. The hypothesis was that there would be no significant difference between GDPs and endodontists. Methods: General dental practitioners (n=603) and endodontists (n=132) had access to high quality images of 12 periapical radiographs. The images had been previously scanned to obtain the same resolution as the original radiograph. Each was presented to observers as an exact replica of the size of a size 2 periapical film. Six radiographs demonstrated the presence of an early periapical lesion on a specific tooth whilst the remaining six radiographs showed normal periodontium. Each radiograph was printed on high quality paper. Each participant was asked to examine a specific tooth for the presence/absence of apical pathosis. Results: The mean sensitivity and specificity for the endodontists was 0.65 and 0.73 respectively and, for the GDPs, mean sensitivity was 0.53 and specificity 0.66. The independent T-test found a significant difference (p<0.001) for both sensitivity and specificity between GDPs and the endodontists. The study also found a significant difference between the sensitivity and specificity of GDPs and their undergraduate education (p-value of 0.01 and <0.001 respectively). GDPs also recorded a significant difference between attending continuing education courses in radiology and their specificity (p< 0.004). Conclusions: Endodontists were more able than GDPs in recognising apical pathology. Attending postgraduate courses in radiology interpretation increased the specificity of GDPs.

“…9,[12][13][14][15][16][17][18] The results of the present study indicate that general dental practitioners are more able to detect periapical changes and canal calcification changes in radiographs when there were moderate to extensive in nature (Tables 3 and 4), but when these changes were to a milder degree they were more likely to be missed by a practitioner. Periapical changes of grade 4 and 5 (according to PAI) were detected by 14-17 practitioners for all the groups of teeth, whereas grade 1 and 2 periapical changes (according to PAI) were detected only by 1-3 practitioners, and 16-18 practitioners missed the radiographic changes altogether.…”

“…[6][7][8][9] From an intraoral periapical view radiograph, the following radicular findings should be assessed: 4,10,11 1. length of root 2. curvature of root both mesial-distal and buccallingual curvatures This inconsistency is due to wide variation in interpretation among different observers and within the same observers at different times. 9,[12][13][14][15][16][17][18] Kaffe et al 9 suggested providing dentists with better radiographic diagnostic criteria for a more consistent evaluation of radiographs and to find the most important and reliable radiographic features that will enable the clinician to interpret them correctly. The purpose of this study was to evaluate which radicular radiographic features the general dentists will want to interpret in a pre-operative diagnostic intraoral periapical radiograph for root canal treatment, determine which radicular radiographic features general dentists interpret correctly and which ones they miss in an intraoral diagnostic periapical radiograph and correlate how correctly general dentists are able to interpret radicular radiographic features that they want to interpret for root canal treatment.…”

Objectives: The aim of this study was to evaluate which radicular radiographic features general dentists want to interpret, determine which of the radicular radiographic features general dentists interpret and which ones they miss in a diagnostic radiograph and correlate how accurately general dentists are able to interpret radiographic features. Methods: 20 general dental practitioners were selected and given 2 sets of questionnaires. The first set asked them to fill out the findings they would elucidate in a diagnostic radiograph while the second set consisted of 30 randomly selected intraoral radiographs to interpret. Results: In the first set of questionnaires, more than 50% of dentists said they would interpret periapical changes, calcification, root curvature and the number of root canals. Less than 50% said they would interpret canal morphology, open apex, resorption, fracture, number of roots and lamina dura. In the second set of questionnaires, more than 90% missed grade 1 or 2 periapical changes (according to periapical index scoring), resorption and canal calcification. More than 80% of dentists missed extra roots and root curvature buccally while no dentists were able to interpret the periodontal ligament width changes, lamina dura and canal variation (C-shape). Using a paired t-test, there was significant variation in answers between the first set and second set of questionnaires. Conclusion: It is concluded from this study that general dental practitioners are able to detect radiographic changes when they are extensive but they miss periodontal ligament width and lamina dura changes.
