Despite the likely widespread use of this modality, recent research detailing errors on DPRs is scarce.Materials and methods: A consecutive case series was performed, including 178 DPRs from patients aged 6 to 12 years. Each DPR was reviewed for 10 distinct errors. The findings were analyzed to identify potential solutions.Results: Nearly three-quarters of the DPRs contained multiple errors. Linear regression analysis indicated that the number of errors decreased with increasing patient age; however, this trend was not statistically significant. Notably, 3 groups of errors (2 errors each) frequently appeared together on the same DPR. When similar errors were grouped, the error incidence decreased significantly with age. Both leftward head tilting and rightward head rotation were observed, likely attributable to the design of the DPR room and the door location. The inter-rater and intra-rater reliability agreements were deemed \"substantial\" or \"almost perfect, beyond chance\" for the detection of most errors, particularly the most frequent types, which involved the \"chin,\" \"tongue,\" and \"lips-open\" positions.Conclusion: As a pediatric patient ages, the number of DPR errors decreases. The results suggest several pre-exposure strategies that could reduce the error rate. These include, monitoring for a \"lips-open\" position as an indicator of a potential \"tongue\" error (occluding the palate-glossal space), and implementing dry runs. Asymmetries observed on DPR must be documented and should prompt re-examination, as they may be genuine.","PeriodicalId":51714,"journal":{"name":"Imaging Science in Dentistry","volume":"54 4","pages":"336-344"},"PeriodicalIF":1.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11685301/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These protocols are intended for standardized periodontal assessment and follow-up, utilizing cone-beam computed tomography (CBCT) images and manipulation of Digital Imaging and Communications in Medicine (DICOM) viewer software.Materials and methods: Two experienced oral and maxillofacial radiologists developed 5 distinct radiographic measurement protocols. These techniques were established to assess the alveolar bone level of a periodontally affected upper central incisor using a method that is consistently repeatable across observers. Two additional assessors, blinded to the details of the study, independently applied the protocols to retrieved DICOM files that met the eligibility criteria. A scoring system with 3 subscores was created and used to compare the protocols.Results: Statistically excellent inter-observer reliability was observed for all protocols, other than protocol 1, which demonstrated moderate reliability. The average discrepancy between measurements taken by the 2 observers was 1.2 mm for protocol 1, 0.81 mm for protocol 2, and less than 0.5 mm for the remaining 3 protocols. All approaches except protocol 4 were straightforward to apply.Conclusion: This study introduces multiple reliable protocols for the evaluation of periodontal bone levels that ensure consistency across observers. Based on the findings, the double axial lines and incisocrestal distance protocols are recommended. These new assessment approaches, along with any future modifications, may be useful in periodontal assessment, dental implant follow-up, orthodontic evaluation, research, and artificial intelligence model generation.","PeriodicalId":51714,"journal":{"name":"Imaging Science in Dentistry","volume":"54 4","pages":"354-361"},"PeriodicalIF":1.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11685304/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three-dimensional (3D) CBCT head measurements obtained through manual and automatic landmarking were compared.Materials and methods: A total of 80 CBCT scans were divided into 3 groups: non-surgical (39 cases); surgical without hardware, namely surgical plates and mini-screws (9 cases); and surgical with hardware (32 cases). Each CBCT scan was analyzed to obtain 53 measurements, comprising 27 lengths, 21 angles, and 5 ratios, which were determined based on 65 landmarks identified using either a manual or a 3D automatic landmark detection method.Results: In comparing measurement values derived from manual and artificial intelligence landmarking, 6 items displayed significant differences: R U6CP-L U6CP, R L3CP-L L3CP, S-N, Or_R-R U3CP, L1L to Me-GoL, and GoR-Gn/S-N (P<0.05). Of the 3 groups, the surgical scans without hardware exhibited the lowest error, reflecting the smallest difference in measurements between human- and artificial intelligence-based landmarking. The time required to identify 65 landmarks was approximately 40-60 minutes per CBCT volume when done manually, compared to 10.9 seconds for the artificial intelligence method (PC specifications: GeForce 2080Ti, 64GB RAM, and an Intel i7 CPU at 3.6 GHz).Conclusion: Measurements obtained with a deep learning-based CBCT automatic landmarking algorithm were similar in accuracy to values derived from manually determined points.

The thickness of copper (Cu) was increased from 0 to 2.2 mm, and 10 different DAP levels were used. The QUART DVT_AP phantom and pediatric radiologic dentiform were scanned under the respective DAP levels. The contrast-to-noise ratio (CNR), image homogeneity, and modulation transfer function (MTF) were analyzed using the QUART DVT_AP phantom. An expert evaluation (overall image grade, appropriateness of field of view, artifacts, noise, and resolution) was conducted using pediatric dentiform images. The critical DAP level was determined based on phantom and dentiform analysis results.Results: CNR and image homogeneity decreased as the DAP was reduced; however, there was an inflection point of image homogeneity at Cu 1.6 mm (DAP=138.00 mGy·cm2), where the value started increasing. The MTF showed constant values as the DAP decreased. The expert evaluation of overall image grades showed \"no diagnostic value\" for dentiform images with Cu 1.9-2.2 mm (DAP=78.00-103.33 mGy·cm2). The images with Cu 0-1.6 mm (DAP=138.00-1697.67 mGy·cm2) had a \"good,\" \"moderate,\" or \"poor but interpretable\" grade.Conclusion: Reducing DAP beyond a 1.6-mm Cu thickness degraded CBCT image quality.

This exposure is comparable to 22 days of background radiation and is notably lower than the radiation exposure from medical CT scans. According to the risk assessment analysis, the risk of stroke events involving internal and external carotid artery calcification (CAC) was 202 and 67 per 100,000 individuals, respectively. In contrast, the estimated risk of radiation-induced cancer associated with CBCT was notably lower, at 0.6 per 100,000.Conclusion: The present study advocates for a comprehensive assessment of CBCT scans encompassing the areas of the internal and external carotid arteries by a knowledgeable professional, given the potential advantages of early detection of vascular abnormalities. Dental professionals who take scans involving these areas need to be mindful of reporting these findings and refer patients to their primary care physician for further investigation.","PeriodicalId":51714,"journal":{"name":"Imaging Science in Dentistry","volume":"54 3","pages":"283-288"},"PeriodicalIF":1.7,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11450408/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142382363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
