“…In the present study, the second most common error was head turned to one side as 14.5%. In the study by Kattimani et al the error of head turn to one side was found to be 30.8% (34), and the finding was correlated with that reported in the study by Khotor et al stating the error as 33.8% (35). In our study, the third most common error was chin tipped low as 13.3% (n=121).…”

Aim: The aim of this study is to determine the effects of working days and hours on panoramic and periapical radiographic errors and investigate the association between patient-induced cephalometric radiographic errors and skeletal malocclusions. Methodology: Obtained from archives of Manisa Dental Health Center, 1402 periapical, 1329 panoramic, and 309 cephalometric radiographs were investigated retrospectively between January-June 2018, and the radiographic errors were determined. Periapical, panoramic, and total errors were grouped according to the number of radiographs, day intensity, and acquisition date and time for each day. Cephalometric radiographs were not included to determine the effects of working hours and days on radiographic errors since the radiographs were taken over the weekend. Patient-induced cephalometric radiographic errors were investigated under the classification of skeletal malocclusions. The independent sample t-test was used to investigate the average range difference between two independent groups for normally distributed variables. However, in situations where the assumption of normality was not met, the Mann-Whitney U test was performed. Results: Total errors were mostly detected on Tuesday (p=0.035). Errors of panoramic and periapical radiographs acquired in the afternoon were higher than those of the radiographs acquired before noon only on Monday (p=0.024, p=0.035). The most common errors observed in periapical radiographs were the positioning errors (23.9%) and cone cut (17.3%), respectively. The most common errors observed in panoramic radiographs were chin tipped high (17.00%), and head turned to one side (9.9%), respectively. Among Class I, II, and III malocclusions, open lips were observed as the most frequent cephalometric radiographic errors (28.6, 15.4, and 16.1%, respectively). Conclusion: The percentage of radiographic errors increases with the intense workload. An anatomical structure may lead to patient-induced cephalometric radiographic errors.

“…The third most common error in this study was the head being rotated towards one side seen in 16.4% which caused asymmetrical condyle and ramus 9,[16][17][18] . In comparison with other studies, it was found that this error was in a similar range to one adult study (17.4%) 6 .…”

“…The least common error was patient movement during exposure which caused blurring on the radiograph and also step defects on the inferior border of the mandible 5,6,16,18,19 . Children and adolescents may not remain quiet and motionless during the panoramic procedures and movement errors could be more prevalent among our study group.…”

Background/Aim: Improper positioning of the patient reduces the diagnostic quality of panoramic radiographs. It is important to perfect the panoramic patient positioning technique to avoid unnecessary repeat exposures especially in pediatric patients. In this study, pediatric patient sample of records collected from an oral and dental health center were analyzed to determine the relative incidence of positioning errors of panoramic radiographs. Material and Methods: 3788 (1928 girls, 1860 boys) digital panoramic radiographs obtained from the stored data in the system were selected randomly. The radiographs were evaluated by two radiology specialists, by recording separately. The positioning errors of the images were categorized into ten groups: the chin tipped high, chin tipped low, a slumped position, the patient positioned forward, the patient positioned backward, failure to position the tongue against the palate, patient movement during exposure, the head tilted, and the head turned to one side. The results were statistically analyzed for positioning errors according to age and gender. Results: In 3788 radiographs, 2138 (56.4%) were error-free and 1650 (43.6%) were present with positioning errors. In the improper images, a single positional error was present in 1379 (83.6%); two positional errors were present in 248 (15%) and three or more positional errors in 23 (1.4%). The most common error observed was the tongue not being in contact with the hard palate (32.1%). On the other hand, the least common experienced error was patient movement during exposure (2.0%). Conclusions: The positioning errors of panoramic radiographs were common in the sample group of this study. Careful patient positioning can play a significant role in improving the radiographic quality and reducing the number of retakes.

“…[21][22][23] Among all the positional errors mentioned above, the most common error is the failure to keep the tongue against the palate. [24][25][26] Due to the failure of holding the tongue against the palate, the palatoglossal airspace (PGA) appears in panoramic radiographs as a dark radiolucent band under the hard palate and on the apices of the anterior maxillary teeth. 27,28 This artefact significantly reduces the quality of the panoramic radiograph as it may be difficult or impossible to interpret the desired periapical region for correct diagnosis and treatment planning (for example, making it difficult to interpret cystic lesions in the anterior area of the upper jaw).…”

“…The typical patient positioning errors in PR include failure to rest the tongue against the palate, head positioned forward, head positioned backward, head twisted towards the left or right, head tilted to the left or right, the chin too high, the chin too low, a slumped position and inadequate neck extension, not resting the chin on the chin support, failing to use the bite guide, lips opened, patient movement during imaging and not removing the metal objects or prostheses 21–23 . Among all the positional errors mentioned above, the most common error is the failure to keep the tongue against the palate 24–26 …”

IntroductionPanoramic radiography quality can be impaired by some errors such as positioning errors. Palatoglossal air space shadow error is one of the most common positioning errors and it is due to the tongue not sticking to the roof of the palate. Techniques used to deal with this error might help prevent unnecessary radiation to patients and save them time and money. The study aimed to investigate the effects of using celluloid matrix and edible tapes (fruit leather and chewing gum) on reducing the palatoglossal air space shadow error in panoramic imaging.MethodsIn our study, 270 patients referred to the Department of Radiology were randomised into three groups: a control group, a celluloid matrix group and an edible tapes group. Before panoramic imaging, all patients were instructed to adhere their tongues to the roof of their mouths, with the distinction that for the celluloid matrix and edible tapes groups, patients were asked to place celluloid tapes, fruit leathers, or chewing gums on their tongues before doing so. The routine imaging process was then performed, and the results were compared across groups to evaluate the incidence of palatoglossal air space shadow error.ResultsThe number of error‐free images in each fruit leather, chewing gum and celluloid tape group were significantly higher than the control group (all cases P < 0.05). The chances of error‐free images in the fruit leather groups were the highest (9.57 times). The age (P = 0.136) and gender (P = 0.272) of patients had no significant effect on the results of interventions.ConclusionThe application of fruit leathers, chewing gums and celluloid tapes reduced the palatoglossal air space shadow error of panoramic imaging.
