Evaluation of diagnostic accuracy of conventional and digital periapical radiography, panoramic radiography, and cone-beam computed tomography in the assessment of alveolar bone loss

Abstract

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.

A six-site method for the evaluation of periodontal bone loss in cone-beam CT images

“…In the search of literature, we found that most of the studies focusing on the measurement accuracy of periodontal bone loss/defect were in vitro studies. [7][8][9][15][16][17][18][19][20] Only one in vivo study was performed on the measurement accuracy of bone defects on the maxillary molar. 21 Although there are a few more in vivo studies with regard to periodontal bone height measurement using CBCT, two of which are case reports, 22,23 others compared different methods of measuring guided tissue regeneration-treated bone defects and furcation lesions.…”

Bone volume changes after immediate implant placement with or without flap elevation

“…Moreover, measurements taken on this radiographs should be considered cautiously since the image always has some degree of distorsion even if they are taken in a standardized way. A study comparing measurements taken on periapical radiographs and direct measurements in cadavers with a caliper showed statistically significant differences between the two methodologies (Takeshita et al 2014).…”

“…A study comparing intrasurgical measurements on teeth with those obtained on CBCTs have shown a high degree of accuracy (Takeshita et al 2014). …”

External Marker in Bisecting-Angle-Technique: A New Approach to Minimize Dental Radiographic Error

“…In clinical situation, the accuracy of image has to be taken into account when selecting periapical radiographic techniques. Several studies (Rushton & Horner 1994;Coelho et al 2007;Takeshita et al 2014) have shown that radiographic images acquired using PT were generally more accurate than images acquired with bisecting-angle-technique. Thus, PT is still recommended as first line approach in periapical radiography since no significant association in the total number of errors was found between PT and BAT-M.…”
