    Change in Periapical Lesion and Adjacent Mucosal Thickening Dimensions One Year after Endodontic Treatment: Volumetric Cone-beam Computed Tomography Assessment
    (2017) Kamburoglu, Kivanc; Yilmaz, Funda; Gulsahi, Kamran; Gulen, Orhan; Gulsahi, Ayse; https://orcid.org/0000-0003-3510-7265; 28132708; AAX-5565-2021
    Introduction: Changes in periapical lesion dimensions along with mucosal thickening after endodontic treatment have not been studied yet. Therefo1e, the objectives of this study were (1) to obtain linear and volumetric measurements of lesion dimensions in maxillary first molars with periapical pathology and (2) to measure maxillary sinus mucosal thickening in the vicinity of periapical lesions before and 1 year after endodontic treatment by using cone-beam computed tomography (CBCT). Methods: Twenty-one maxillary first molar teeth of 21 patients (14 female and 7 male) with periapical lesion that had local mucosal thickening in the vicinity of the periapical lesion were endodontically treated. A total of 21 maxillary first molar roots (8 mesiobuccal roots, 6 distobuccal roots, and 7 palatal roots), each one from different patients, was included. Pretreatment and 1-year post-treatment CBCT images of each tooth were obtained by using Kodak CS 9300 3D CBCT unit. Width, height, surface area, and volume measurements of periapical lesions and mucosal thickening of the maxillary sinus mucosa in the vicinity of the periapical lesion were measured before and 1 year after endodontic treatment. General linear model (analysis of variance) was used for the comparisons between measurements, and significance was set at P <.05. Regression analysis was also used to test the correlation between different measurements. Results: We found statistically significant differences between mean pretreatment and mean post-treatment measurements conducted by using CBCT images (width, P =.002; height, P <.001; maximum mucosal thickening, P <.001; medium mucosal thickening, P <.001; minimum mucosal thickening, P <.001; surface area, P =.032; and volume, P =.034). Considering gender, age, and root type variables, no significant differences were found for all the measurements conducted (P >.05). There were 36%, 41%, 53%, 54%, 53%, 73%, and 75% mean reductions in lesion width, lesion height, maximum sinus mucosal thickness, medium sinus mucosal thickness, minimum sinus mucosal thickness, lesion surface area, and lesion volume, respectively, before and 1 year after endodontic treatment. Regression analysis of pretreatment lesion volume versus percentage of post-treatment lesion volume change revealed a low regression coefficient (R2 = 16.7%, P >.05), showing a weak linear relationship. Conclusions: CBCT assessment of changes in periapical lesion and mucosal thickening dimensions may reveal useful information regarding endodontic treatment success.

    Versatility of high resolution ultrasonography in the assessment of granulomas and radicular cysts: a comparative in vivo study
    (2019) Sonmez, Gul; Kamburoglu, Kivanc; Yilmaz, Funda; Koc, Cemre; Baris, Emre; Tuzuner, Aysegul; 31188679
    Objectives: To evaluate and compare the diagnostic potential of high resolution ultrasound with periapical radiographs (PR) and CBCT in assessing granulomas and radicular cysts. Methods: This study included a total of 33 teeth from 33 patients with periapical lesions. Subjects were distributed among three groups. A consisted of teeth that were extracted. B consisted of teeth treated with root-canal treatment followed by apical surgery. C consisted of teeth treated with root-canal treatment only. Pre-treatment PR, ultrasound and CBCT images were obtained for Groups A, B and C and 6 month post-treatment PR and ultrasound images were obtained for Groups B and C. In addition, histopathological analysis was performed on lesions in Groups A and B. Lesions were classified as either cystic lesions or granulomas. Width, height, depth, surface area and volume of lesions were measured using the built-in softwares of the appropriate imaging modalities. Measurements were compared by Wilcoxon and paired sample t tests. Ultrasound and histopathological findings were compared with lc and Mc Nemar. Statistical significance was set at p < 0.05. Results: kappa coefficient (0.667; p = 0.002) suggested good agreement between ultrasound and histopathology. No statistically significant differences were found among periapical radiography, CBCT and ultrasound in the pre-treatment measurements of lesion width ( p = 0.308) or between CBCT and periapical radiography in the pre-treatment measurements of lesion height ( p = 0.863). In all cases, mean measurement values for all variables were lower for ultrasound than for CBCT. Conclusion: Ultrasound provided useful information for the diagnosis and assessment of granulomas and radicular cysts.

    Comparison of periapical radiography, panoramic, and cone-beam CT in the detection of dental caries in dog teeth
    (2019) Orhan, Kaan; Ozemre, Mehmet Ozgur; Secgin, Cansu Koseoglu; Vural, Sevil Atalay; Gur, Gurkan; Kamburoglu, Kivanc
    The aim of this study was to compare the effectiveness of panoramic, periapical and two different Cone Beam Computed Tomography (CBCT) devices in the detection of dental caries of dog teeth ex vivo. A total of 880 teeth were investigated, 33 of which were with caries, whereas; 33 healthy teeth were the controls. Periapical, panoramic and CBCT scans were made for the assessment of the teeth. All images were evaluated separately by two observers experienced in image interpretation. The presence or absence of occlusal caries was scored using a 5-point scale. Kappa values were calculated to assess intra and interobserver agreement. Receiver Operating Characteristic (ROC) analysis was performed to compare the effectiveness of different imaging methods in the detection of dental caries. For both observers, the order of success of the image sets in the estimation of the caries tooth was CBCT Morita, CBCT Iluma, periapical and panoramic radiograph (Area Under Curve (AUC): 0.929, 0.882, 0.861, and 0.704 for observer 1, AUC: 0.927, 0.896, 0.875, and 0.693 for observer 2, respectively). CBCT was found to be the best imaging method for the ex vivo detection of caries in dog teeth. In addition, panoramic images performed worse than all other modalities.
