Comparison of Radiovisiography and Digital volume tomography to direct surgical measurements in the detection of infrabony defects

Background:To evaluate the diagnostic accuracy of different radiographic methods in the assessment of proximal alveolar bone loss (ABL).Materials and Methods:ABL, the distance between cement-enamel junction and alveolar bone crest, was measured in 70 mandibular human teeth – directly on the mandibles (control), using conventional periapical radiography with film holders (Rinn XCP and Han-Shin), digital periapical radiography with complementary metal-oxide semiconductor sensor, conventional panoramic, and cone-beam computed tomography (CBCT). Three programs were used to measure ABL on the images: Image tool 3.0 (University of Texas Health Sciences Center, San Antonio, Texas, USA), Kodak Imaging 6.1 (Kodak Dental Imaging 6.1, Carestream Health®, Rochester, NY, USA), and i-CAT vision 1.6.20. Statistical analysis used ANOVA and Tukey's test at 5% significance level.Results:The tomographic images showed the highest means, whereas the lowest were found for periapical with Han-Shin. Controls differed from periapical with Han-Shin (P < 0.0001). CBCT differed from panoramic (P = 0.0130), periapical with Rinn XCP (P = 0.0066), periapical with Han-Shin (P < 0.0001), and digital periapical (P = 0.0027). Conventional periapicals with film holders differed from each other (P = 0.0007). Digital periapical differed from conventional periapical with Han-Shin (P = 0.0004).Conclusions:Conventional periapical with Han-Shin film holder was the only method that differed from the controls. CBCT had the closest means to the controls.

“…DVT provides high definition, three dimensional digital data on precise anatomical information of all oral and maxillofacial structures at reduced cost and less radiation to patient, in comparison to traditional imaging systems like orthopantomography, which are limited by distortion, magnification changes, restricted clarity, lack of accuracy in measurements and not allowing for 3D modelling. 5 Cone Beam scanners are based on a cone shaped beam of x-rays rotating around the object of interest giving a volume of data, using a 2-dimensional extended digital array as an area detector. The technique involves a single 360-degree scan in which the x-ray source and reciprocating area detector synchronously move around the patient's head, which is stabilized with a head holder.…”

Background: Maxillary sinus and its close proximity to the oral cavity make it a common clinical concern for medical and dental practitioners. Due to anatomical complexities, it is difficult to evaluate the relation between the root apices of maxillary posterior teeth and the floor of maxillary sinus which is essential for diagnosis of sinus pathology, understanding the path of dental infection and planning of dental treatment. Aims and Objectives: To correlate the topographic relationship of the maxillary sinus floor to the maxillary posterior teeth roots as imaged by pairs of Orthopantomograph (OPG) and Digital Volumetric Tomography images (DVT). Materials and Methods: A total of 510 maxillary teeth from 85 patients were classified according to their topographic relationship to the maxillary sinus and measured according to their projection lengths on the sinus cavity using OPG and DVT modalities. Results: In cases of classification 0, 85% and in classification 1, 55.3% cases shows similar classification in both OPG and DVT. 28.5% of cases in both imaging modalities show classification 2. Only 15.9% of teeth roots exhibits classification 3. 11.1% of cases showed classification 4.The panoramic radiograph showed a statistically significant 2.24 times longer root projection on the sinus cavity in OPG comparison to DVT images. Conclusion: Teeth roots projecting in to the sinus in OPG, shows no vertical protrusion in to the sinus in DVT images. Hence DVT was better than OPG with measurements that were more exact and closer to anatomical reality.

Objectives The aim of this study was to address the diagnostic efficacy of cone beam computed tomographic (CBCT) imaging in periodontics based on a systematic search and analysis of the literature using the hierarchical efficacy model. Methods A systematic search of the electronic databases such as PubMed, Scopus, Web of Science, and Cochrane was conducted until February 2019 to identify studies addressing the efficacy of CBCT imaging in Periodontics. The identified studies were subjected to pre-identified inclusion criteria followed by an analysis using a hierarchical model of efficacy (model) designed for an appraisal of the literature on a diagnostic imaging modality. Two examiners performed the eligibility and quality assessment of relevant studies, and consensus was reached where disagreement was found.Results The search resulted in 64 studies. Of these, 35 publications were allocated to the relevant level of efficacy and quality assessments wherever applicable. The overall diagnostic accuracy studies showed the risk of bias and applicability concerns in the use of CBCT to be low to moderate. In addition, CBCT is accurate in identifying periodontal defects when compared to other modalities. The studies on the level of patient outcomes agreed that CBCT is a reliable tool for the assessment of the outcomes after the treatment of periodontal defects. Conclusion CBCT was found to be beneficial and accurate in cases of infra-bony defects and furcation involvements.
