“…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.…”

Objectives: In contrast to two-dimensional planar images, a measuring point is hardly repeatedly determined in a CBCT image when alveolar bone loss is assessed. Thus, the aim of the present study was to propose a six-site measuring method, which is closely related to anatomical structure, for the evaluation of alveolar bone loss in CBCT images. Methods: 150 measuring points in 11 molars and 14 premolars from 6 patients (2 males and 4 females) were included. CBCT images of the teeth were acquired prior to periodontal surgery. Four observers measured the distances between cemento-enamel junctions and the apical bases of the periodontal bone defect at the mesio-buccal, mid-buccal, disto-buccal, mesio-lingual/palatal, mid-lingual/palatal and disto-lingual/palatal sites in CBCT images. Direct measurements of the six sites were correspondingly obtained in the subsequent periodontal surgeries. Differences between the distances measured in the CBCT images and during the surgery were analysed. Interobserver and intraobserver variances were tested. Results: No statistically significant difference was found between the surgical and CBCT measurements (p 5 0.84). Diagnostic coincidence rates of four observers were 86.7%, 87.3%, 88.7% and 88.0%, respectively. The interobserver (p 5 0.95) and intraobserver (p 5 0.30) variances were not significant. Conclusions: The six-site measuring method validated in the present study may be a useful three-dimensional measuring method for the evaluation of periodontal disease.

“…Various imaging and estimation techniques have been used in many studies to assess alveolar bone [13,14]. It is clear that 3D CBCT imaging has the greatest advantage over 2D intraoral radiography for evaluating buccal and lingual alveolar bone [15].…”

Objective No studies have yet evaluated linear alveolar bone levels and extraction socket dimensions on dry skulls using different techniques. We aimed to investigate the accuracy of cone-beam computed tomography (CBCT), digital radiography, and digital photography. Methods Circumferential linear alveolar bone level measurements were performed at six sites on the examined teeth using gutta-percha points placed for reference at the cementoenamel junction and alveolar bone crest. Dimensions of the extraction socket were evaluated by linear measurements in the mesiodistal and buccolingual directions. Groups were formed according to the following imaging and estimation techniques: (1) direct measurement using digital calipers under loupe magnification (gold standard); (2) direct measurement using only digital calipers; (3) digital photographs/ImageJ (Photo/I); (4) digital paralleling long-cone periapical radiographs/ImageJ (Periapical/I); (5) digital panoramic radiographs/digital calipers; (6) digital panoramic radiographs/digital calipers and loupe magnification; (7) digital panoramic radiographs/ImageJ; and (8) CBCT/ImageJ (CBCT/I).Results Statistical analyses showed significant differences for all panoramic radiography subgroups in all examined regions compared with the gold standard (p \ 0.001). Results of the CBCT/I (r = 0.930, p \ 0.01), periapical/I (r = 0.939, p \ 0.01), and Photo/I (r = 0.978, p \ 0.01) techniques showed high correlation with the gold standard. Reliability of repeated measurements was higher with loupe magnification and the image-processing program.Conclusions Periapical/I and CBCT provide promising results in analyses of the dimensions and relations of periodontal tissues. Routine clinical digital photographs can be converted to scaled images and applied to treatment planning and preoperative-postoperative comparisons.

“…Several studies have analyzed CBCT applications in implantology [5, 6], oral surgery [6–8], endodontics [9] and orthodontics [10]. Studies conducted with database images [11], human cadavers [12–19], swine mandibles [12, 20, 21] and patients with chronic periodontitis [22–24] have analyzed CBCT performance in diagnosis and treatment planning in periodontics. These studies suggest that CBCT is more accurate than periapical radiographs in detecting bone craters, dehiscence, fenestration and furcation involvement.…”

“…These studies suggest that CBCT is more accurate than periapical radiographs in detecting bone craters, dehiscence, fenestration and furcation involvement. Nevertheless, as regards one- or two-wall infrabony defects and horizontal bone loss, CBCT superiority over periapical radiographs remains controversial [12–16, 19, 21, 23], because some studies did not compare CBCT performance to periapical radiographs [19, 23]. Even when considering the studies in which comparisons were made, there was no unanimity in favor to CBCT.…”

“…The majority of these studies were conducted with human mandibles [12–19] and most of them used round burrs to simulate periodontal bone defects. However, burrs produce well-defined lesions that do not correspond to the pattern observed clinically [20] and its artificial presentation increases the examiner’s ability to detect bone lesions with CBCT [25].…”

Performance of cone beam computed tomography and conventional intraoral radiographs in detecting interproximal alveolar bone lesions: a study in pig mandibles

BackgroundCone beam computed tomography (CBCT) has been largely used in dentistry. Nevertheless, there is lack of evidence regarding CBCT accuracy in the diagnosis of early periodontal lesions as well as the correlation between accuracy and lesion size. The aim of this study was to evaluate accuracy of CBCT and conventional intraoral radiographs in detecting different-sized interproximal bone lesions created in pig mandibles. The hypothesis was that CBCT accuracy would be superior to radiographs in detecting incipient bone lesions.MethodsTwenty swine dry mandibles were used, totalizing 80 experimental sites. Four groups were created according to exposure time to perchloric acid 70–72%: controls (no exposure), 2-hour exposure, 4-hour exposure, and 6-hour exposure. Standardized CBCT and conventional intraoral radiographs were taken and analyzed by two trained radiologists. The presence of lesions in the dry mandible was considered the gold standard. Sensitivity, specificity, and accuracy in detecting different-sized bone lesions were calculated for CBCT and intraoral radiographs.ResultsAccuracy of CBCT ranged from 0.762 to 0.825 and accuracy of periapical radiography ranged from 0.700 to 0.813, according to examiner and time of acid exposure. Inter-examiner agreement varied from slight to fair, whereas intra-examiner agreement varied from moderate to substantial.ConclusionsCBCT performance was not superior to that provided by conventional intraoral radiographs in the detection of interproximal bone loss.
