Comparing the Accuracy of Cone Beam Computed Tomography,Digital Intraoral Radiography and Conventional Intraoral Radiography in the Measurement of Periodontal Bone Defects

Abstract

ARTICLE INFOBackground and Aim: Cone beam computed tomography (CBCT) produces highquality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects. Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous defects (buccal and lingual infra-bony, inter proximal, horizontal, crater, dehiscence and fenestration defects) were shaped in 13 dry mandibles. CBCT and intraoral radiography with parallel technique by conventional film and digital sensor were compared with the standard reference (digital caliper). Inter and intra observer agreement were assessed using Intra class correlation co-efficient and Pearson correlation. Paired T-Test was applied for the comparison of absolute differences of conventional and digital intraoral radiography and CBCT measurements with the gold standard. All statistical analyses were performed using SPSS® v13.0 statistical software. Results: Inter and intra observer agreement were both high for CBCT (ICC: α=0/88) but moderate for intraoral conventional radiography (ICC: α=0/54) and digital radiography (ICC: α=0/73). No significant differences were detected between the observers for all the techniques (P> 0.05). According to Paired T-test, mean difference for CBCT technique (0.01mm) was lower than digital radiography (0.47mm) and conventional radiography (0.63mm). CBCT allowed the measurement of all lesion types, but intraoral radiography did not allow the measurement of buccal and lingual defects. Conclusion:The results of this study showed that the studied radiographic modalities are useful in identifying the periodontal bone defects. CBCT technique showed the highest accuracy in the measurement of periodontal bone defects compared with digital and conventional intraoral radiography.

Comparison of the Diagnostic Accuracy of Digital Intraoral Radiography with PSP and CBCT in the Detection of Horizontal and Vertical Dental Root Fractures

“…This difficulty in diagnosis leads to unnecessary tooth extractions, poor long-term prognosis and extensive bone loss. (2)(3)(4) In this in vitro study, the diagnostic accuracy of digital intraoral radiography with PSP and CBCT in the detection of HRF and VRF was assessed.…”

Efficacy of Periapical Radiography and Three Cone-Beam Computed Tomography Systems for Detection of Peri-Implant Dehiscence Defects: An in- Vitro Study

“…CBCT is a suitable modality for evaluation of buccal and lingual cortical plates and better visualization of the morphology of bone defects [ 14 - 16 ]. Bagis et al, [ 10 ] and Dehghani et al, [ 17 ] compared the diagnostic accuracy of CBCT with periapical radiography for detection of tunnel, fenestration and dehiscence bone defects and showed higher diagnostic accuracy of CBCT than periapical radiography. Also, they demonstrated that the diagnostic accuracy of CBCT increased with an increase in size of defects, which was in agreement with our findings.…”
