Öğe Accuracy and reliability of enamel and dentin thickness measurements on micro-computed tomography and digital periapical radiographs(Elsevier, 2019) Belgin, Ceren Aktuna; Serindere, Gozde; Orhan, KaanIn the application of scientific human skeletal variation in medico-legal matters, virtual anthropology is the current technique performed to examine skeleton and its body parts. Digital imaging techniques are used in many areas of dentistry and forensic dentistry. Among all digital imaging modalities, digital periapical radiography (PR) are the most widely used, however, new contemporary imaging techniques micro-computed tomography (Micro-CT) can be also used. The aim of this study was to assess the accuracy and reliability of enamel and dentin thickness measurement through intra and inter-observer error analysis, and comparison was made between periapical radiographs and Micro-CT methods. In this study 15 maxillary first premolar were used which extracted for various reasons. Enamel and dentin thicknesses and maximum cervical crown widths (MCCW) of 15 premolar teeth were examined in both Micro-CT and periapical radiographs. The results obtained with the exact maximum cervical crown widths were compared Image J software version. A digital caliper was used to measure the actual MCCW of the teeth. Results exhibited no significant differences in the measurements by the intra or inter-observer error analyses. The intraclass correlation coefficients (ICC) were more than 0.95 by both intra and inter-observer error analyses. There was significant differences in the measurements by PR and Micro-CT methods. By parameters, Micro-CT showed the highest R value (0.962) with the least error in different methods and observers. In conclusion, dentin and enamel measurements by Micro-CT was highly accurate and reliable as in the conventional method (PR). Micro-CT evaluations should be recommended for implementation in the future anthropological studies especially in countries with limited source of dental data.Öğe THE ANATOMICAL AND MEASUREMENT STUDY OF ROSENMULLER FOSSA AND OROPHARYNGEAL STRUCTURES USING CONE BEAM COMPUTED TOMOGRAPHY(Sestre Milosrdnice Univ Hospital, 2022) Serindere, Gozde; Gunduz, Kaan; Avsever, Hakan; Orhan, KaanThe objective of this study was to assess Rosenmuller fossa (RF) anatomy and neighboring structures using cone beam computed tomography (CBCT). A total of 1000 patients were analyzed using CBCT. The reference points were based on the spina nasalis posterior (Snp) and basion. The length between RF and neighboring structures were measured.The mean distance from Snp to the posterior pharyngeal wall was 17.7 mm. The mean distance from right to left torus levatorius was 25.69 mm. The mean depth of right RF was 5.54 mm while the mean depth of left RF was 5.26 mm. RF, also described as the lateral pharyngeal recess, is a source location of nasopharyngeal carcinoma development. Its location is on the lateral pharyngeal wall posterior to the cartilaginous part of the eustachian tube, the torus tubarius. The knowledge of RF is important to diagnose and perform treatment planning of nasopharyngeal carcinoma.Öğe CBCT Visualization of Furcation Perforation Repair Materials Using Different Voxel Sizes(Marmara Univ, Inst Health Sciences, 2021) Orhan, Ayse Isil; Tufenkci, Pelin; Oncu, Aysenur; Sevgi, Sevinc; Celikten, Berkan; Orhan, KaanObjective: Three-dimensional cone-beam computed tomography is gaining popularity as an imaging modality aiding the performance of difficult endodontic treatment procedures. For this reason, we assessed the visualization of bioactive furcal perforation repair materials in an ex vivo study using CBCT with different voxel sizes and determined which voxel size yielding the best images with least artefacts. Visualization of endodontic restorative material is affected by the appearance of various artifacts. This study was conducted to evaluate the CBCT visualization of three perforation repair materials using five different voxel sizes. Methods: This study was performed with 84 mandibular molars that had been extracted for various reasons. All samples were measured with a digital caliper (Digimess, Sao Paulo, Brazil), marked at 3 mm above the cementoenamel junction, and decoronized at this line. The root segments were amputated at 3 mm below the furcation site using diamond discs under water cooling. The openings of the pulp chamber created, following the furcation defects formed. Biodentine, MTA, and EndoSequence were mixed following the manufacturers' instructions and applied to the perforation sites. Five image sets were obtained: 75 micron, 100 micron, 150 micron, 200 micron, and 400 micron. 2 examiners were evaluated the images independently. Results: The best image quality for all repair materials obtained in 100 micron. Image clarity of repair materials showed no significant difference among voxel sizes of 75 and 150 micron. Image quality was significantly reduced at 200 and 400 micron voxel sizes, and the worst quality was obtained at 400 micron voxels in all groups. Conclusions: CBCT imaging can be used to examine endodontic repair materials with adjustment of the effective radiation dose rate and selection of the appropriate voxel size.Öğe A DETAILED CBCT STUDY OF 'CORONOID FORAMINA' AND ACCESSORY FORAMINA OF THE MANDIBLE: A UNIQUE ANATOMIC VARIATION(Sestre Milosrdnice Univ Hospital, 2019) Gunduz, Kaan; Serindere, Gozde; Avsever, Hakan; Orhan, KaanThe aim of the study was to evaluate accessory foramina (AF) located on the medial aspect and to present a unique finding of `coronoid foramina' (CF) along with AF on the mandible. The cone beam computed tomography images of the mandible in 979 patients were retrospectively evaluated for the presence of CF and AF. AF was found in 39 (3.98%) patients. AF located on the medial surface below and above mandibular foramen was found in 15.38% and 84.62% of patients, respectively. CF was confirmed in 20 (2.04%) patients. Mandibular AF is important for surgical procedures in the posterior region of the mandible and for mandibular nerve anesthesia. This study including CF will be useful for further studies due to the lack of literature on the issue.Öğe Determining the reliability of diagnosis and treatment using artificial intelligence software with panoramic radiographs(Korean Acad Oral & Maxillofacial Radiology, 2023) Orhan, Kaan; Belgin, Ceren Aktuna; Manulis, David; Golitsyna, Maria; Bayrak, Seval; Aksoy, Secil; Sanders, AlexPurpose: The objective of this study was to evaluate the accuracy and effectiveness of an artificial intelligence (AI) program in identifying dental conditions using panoramic radiographs (PRs), as well as to assess the appropriateness of its treatment recommendations. Materials and Methods: PRs from 100 patients (representing 4497 teeth) with known clinical examination findings were randomly selected from a university database. Three dentomaxillofacial radiologists and the Diagnocat AI software evaluated these PRs. The evaluations were focused on various dental conditions and treatments, including canal filling, caries, cast post and core, dental calculus, fillings, furcation lesions, implants, lack of interproximal tooth contact, open margins, overhangs, periapical lesions, periodontal bone loss, short fillings, voids in root fillings, overfillings, pontics, root fragments, impacted teeth, artificial crowns, missing teeth, and healthy teeth. Results: The AI demonstrated almost perfect agreement (exceeding 0.81) in most of the assessments when compared to the ground truth. The sensitivity was very high (above 0.8) for the evaluation of healthy teeth, artificial crowns, dental calculus, missing teeth, fillings, lack of interproximal contact, periodontal bone loss, and implants. However, the sensitivity was low for the assessment of caries, periapical lesions, pontic voids in the root canal, and overhangs. Conclusion: Despite the limitations of this study, the synthesized data suggest that AI-based decision support systems can serve as a valuable tool in detecting dental conditions, when used with PR for clinical dental applications.Öğe Efficacy of low dose and ultra-low dose on the visibility of peri-implant fenestration and dehiscences: a computed tomography study(Int Scientific Information Inc, 2022) Aktuna-Belgin, Ceren; Serindere, Gozde; Belgin, Huseyin Berkay; Serindere, Mehmet; Orhan, KaanPurpose: This study aimed to evaluate the visibility of peri-implant fenestration and dehiscences on computed tomography (CT) images taken with 2 different doses. Material and methods: The defects were created on the apical of 6 implants randomly selected from 20 titanium implants placed in the ribs, and dehiscences were created on the cervical of 8 implants. No defects were created around 6 implants. Macroscopic analysis of the implanted ribs was accepted as the gold standard. From the samples, images were taken by using both ultra-low dose (80 kVp, 50 mA, 1.25 mm slice thickness) and low dose (100 kVp, 50 mA, 1.25 mm slice thickness) protocols in CT. The images obtained were evaluated using a 5-point scale. Results: No significant difference was found between the area under the receiver operating characteristic of ultra-low dose protocol and low dose protocol in both defects based on the Wilcoxon test (p > 0.05). Conclusions: The ultra-low dose protocol could be applied by adhering to the as low as reasonably achievable principle in the diagnosis of peri-implant defects.Öğe Evaluation of The Ethmoid Bone Using by Cone Beam Computed Tomography In Turkish Subpopulation(Marmara Univ, Inst Health Sciences, 2021) Belgin, Ceren Aktuna; Bayrak, Seval; Orhan, KaanObjective: The objective of this retrospective study was to evaluated anatomical structures of ethmoid bone on cone beam computed tomography (CBCT) images in a Turkish subpopulation. Methods: The CBCT images of 200 patients (116 female and 84 male), between the age of 18 and 50 years, who met the study criteria were selected randomly. The medial ethmoid roof height (MERH), cribriform plate height (CP), the height of the lateral lamella of the cribriform plate (LLCP) were measured. All the data were grouped by age, side, and gender. Results: For MERH; the mean heights for the left and the right side were 25.55 +/- 3.00 mm and 25.24 +/- 3.01 mm, respectively. There was no significant difference between right MERH and genders (p>0.05). The mean LLCP heights on the right and left sides were 4.98 +/- 2.12 mm and 4.49 +/- 1.64 mm, respectively. It was found that LLCP height did not have a statistically significant correlation with gender (p>0.05). The average of right and left CPH were calculated 20.55 +/- 2.61 mm and 20.82 +/- 2.75 mm, respectively. Both the right and left CPH were significantly higher in males (p<0.05). Also, there was no correlation between the height of the anatomical structures of the evaluated ethmoid bone and the increase or decrease in age (p>0.05). Conclusion: Morphological differences in the anatomy of ethmoid bone were shown in this study. The anatomical structures showing changes due to factors such as side, age, gender, and race should be examined in three dimensions before the operation.Öğe Evaluation of the Relationship Between Olfactory Fossa Measurements and Nasal Septum Deviation for Endoscopic Sinus Surgery(Lippincott Williams & Wilkins, 2020) Bayrak, Seval; Belgin, Ceren Aktuna; Orhan, KaanIntroduction: Endoscopic sinus surgeries (ESS) are frequently used in the treatment of optic nerve decompression, other intracranial lesions and sinonasal pathologies. The olfactory fossa can be localized on different levels in relation to the anterior cranial fossa. The aim of the present study was to evaluate the depth and width of the olfactory fossa (OF) in relation to nasal septum deviation (NSD). Methods: A total of 225 patient (141 female and 84 male, age range between 15 to 56 years) of cone beam computed tomography (CBCT) data was used in this study. NSD, OF width, OF depth were measured. OF depth which was grouped according to the Keros classification as Type I, II, and III was calculated. All measurements were performed bilaterally except for NSD. Results: In the right and left OF depth were found Keros Type I 32 (14.2%) and 30 (13.3%), Keros Type II 171 (76%) and 167 (74.2%), and Keros Type III 22 (9.8%) and 28 (12.4%) respectively. There was no statistically significant found between OF depth and NSD (P > 0.05). The mean angle of the NSD in men and women were 4.36 +/- 4.69(o)in women 4.11 +/- 4.36(o), respectively. The mean width of the right OF was 2.50 +/- 0.64 mm and 2.58 +/- 0.72 mm for the left side and there was no statistically significant association between OF width - NSD and OF width - OF depth (P > 0.05). Conclusion: The anatomy of the OF should be well established before surgical intervention increase of the length of the lateral lamella is also increases the risk of developing complications such as cerebral damage, hemorrhage, and cerebrospinal fluid fistula during endoscopic sinus surgery. Although there is no significant difference between OF measurement and NSD, with three-dimensional imaging detailed research is required before endoscopic sinus surgical operations.Öğe Evaluation of the sealing ability of different root canal sealers: a combined SEM and micro-CT study(Univ Sao Paulo Fac Odontologia Bauru, 2018) Huang, Yan; Orhan, Kaan; Celikten, Berkan; Orhan, Ayse Isil; Tufenkci, Pelin; Sevimay, SemraObjective: The purpose of this study was to analyze the ability of multiple compounds to seal the dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT). Material and Methods: Twenty-four single-root human mandibular premolars were selected and instrumented with nickel-titanium rotary file and the final file size was # 40/06. They were then randomly allocated into 2 groups, and all samples were filled with single cone gutta-percha (# 40/06) and one of the tested sealers (AH Plus and EndoSequence BC sealers). All specimens were scanned using micro-CT and then three from each group were randomly selected for SEM analysis. Results: According to SEM, both root canal sealers showed sufficient adaptation to dentin along the whole length of the root canal, though the coronal sections presented superior sealing than the apical sections. Micro porosity analyses revealed that the volume of closed pores and the surface of closed pores had the largest values in the coronal sections, followed by the middle and the apical sections for both sealants (p<0.05). However, no significant difference was observed for those two parameters between AH Plus and EndoSequence BC sealers in any of the three sections (p>0.05), whereas they were larger in the apical section when the AH Plus sealer was used. Conclusions: By using the single cone technique, neither EndoSequence or AH Plus pro-vides a porosity-free root canal filling. The EndoSequence BC sealer may have similar sealing abilities regarding the whole root canal as the AH Plus sealer. A better sealing effect could be obtained in the coronal and middle sections of a root canal than the apical part by using the tested sealers.Öğe Evaluation of the visibility of peri-implant bone defects using ultrasonography with two types of probes(Medical Communications, 2021) Orhan, Kaan; Serindere, Gozde; Belgin, Ceren Aktuna; Kurt, Mehmet HakanBackground: The aim of the present study was to evaluate the efficacy of intraoral and extraoral ultrasonography evaluations performed with two different types of probes (linear and hockey stick) for the visibility of peri-implant bone defects. Material and methods: Fourteen implants were inserted into sheep heads. Peri-implant bone defects were created without knowing the depth, which served as the gold standard for the defects. The defects were scanned with two different probe types (linear and hockey stick probes) extraorally and intraorally, using two different ultrasonography systems. For intra- and interobserver agreements for each probe types, Kappa coefficients were calculated. Results: The lowest ICC values were found in both intra- (ICC = 0.696) and interobserver reliability (ICC = 0.762) obtained with the extraorally used linear probe. There was a high agreement with the gold standard when using hockey sticky probes intraorally. For both linear probes, there were no significant differences in agreement among the two observers and the gold standard (p >0.05). Conclusions: High agreement was found when using high-frequency hockey stick probes intraorally, which means that they can be used with good effect for the evaluation of the visibility of peri-implant bone defects. To the best of our knowledge, this study is the first one on this subject. Thus, it can be stated that US can be an alternative method of examining defects. However, further studies are needed to evaluate the effectiveness of US in visualizing peri-implant bone defects.Öğe Evaluation of the visibility of the materials used in furcation perforation in imaging devices(Selçuk Üniversitesi, 2020) İçen, Murat; Orhan, Kaan; Tüfenkçi, PelinBackground: Variable radiographic techniques are used for postoperative evaluation of the materials used in furcation perforation. Since it is easily accessible clinically and the radiation dose which the patient is exposed to, is lower than the advanced imaging methods, intraoral imaging is applied. In cases that cannot be determined by 2D radiographs, cone beam computed tomography is more relevant because of the absence of superimpositions and allowing for multiplanar imaging. The aim of this study was to assess the diagnostic acceptability of the radiographic visibility of the materials used in furcation perforations and to find out which radiographic technique was efficient to view the materials.Methods: One hundred and twelve lower molar teeth were used according to the study criteria. Biodentin, BioAggregate, MTA and Endosequence were applied individually to the teeth, in order to repair the perforation zone. Periapical radiographs were obtained with Soredex Digora Optime with photostimulated phosphor plates. Other radiographic images were obtained using Planmeca Dixi 3 CCD, while CBCT images were obtained using Morita Veraviewepocs 3D R100. An endodontist and two dentomaxillofacial radiology specialists evaluated the images of CBCT and periapical radiographs. Teeth were evaluated randomly for the visibility of the repair materials in furcal perforations and scored.Results: MTA and Biodentine presented low image clarity while Bioaggregate and Endosequence had high image clarity. Morita Veraviewepocs 3D R100 depicted the highest sharpness, but no difference was observed between Soredex Digora Optime and Planmeca Dixi 3 devices.Conclusion: In the postoperative follow-up of the materials used in the treatment of furcation perforations, the usage of CBCT and the use of Bioagregate and Endosequence, which provide the best image clarity, has been suggested.Öğe Hatay ilinde oral premalign lezyonların prevalansı: retrospektif bir çalışma(2020) Serindere, Gözde; Aktuna Belgin, Ceren; Gürsoy, Didar; Orhan, KaanBu çalışmanın amacı, 2017 ve 2019 yılları arasında Patoloji Anabilim Dalı'na başvuran hastalarda oral premalign lezyonların(OPL) prevalansını değerlendirmektir.

En sık görülen premalign lezyon liken planus (% 50,6) olarakbulundu. Ağız boşluğunda malignite olasılığını ekarte etmek için biyopsi yapılmalıdır. OPL'lerin erken teşhisi tedavi için önemlidir.Öğe Micro-CT assessment of the sealing ability of three root canal filling techniques(Nihon Univ, School Dentistry, 2015) Celikten, Berkan; Uzuntas, Ceren F.; Orhan, Ayse I.; Tufenkci, Pelin; Misirli, Melis; Demiralp, Kemal O.; Orhan, KaanThis study used micro-CT to compare three obturation techniques with respect to void occurrence in canals filled with bioceramic sealer. Thirty extracted first mandibular premolars were prepared with a ProTaper Universal system and randomly allocated to three groups. Canals were obturated with gutta-percha and bioceramic root canal sealer, using either single-cone, lateral compaction, or Thermafil filling technique. Each tooth was then scanned with micro-CT. Voids in 2D cross-sectional images and void volumes in 3D images of all root thirds were assessed in relation to obturation technique. There was no significant difference between obturation techniques in the proportion of sections with voids (P > 0.05). However, the results of the obturation techniques significantly differed in relation to root region (P < 0.05). In conclusion, no root filling technique resulted in void-free specimens. Void volumes were highest for the single-cone technique and lowest for Thermafil, in all regions (P < 0.05).Öğe Multiple Regression Modeling for Age Estimation by Assessment and Comparison of Spheno-Occipital Synchondrosis Fusion and Cervical Vertebral Maturation Stages(Thieme Medical Publ Inc, 2022) Belgin, Ceren Aktuna; Bayrak, Seval; Orhan, Kaan; Ankarali, HandanObjectives The aim of this study was (1) to evaluate the relationship between spheno-occipital synchondrosis (SOS) fusion stages, cervical vertebral maturation (CVM) stages, and clivus sizes with chronological age on cone-beam computed tomography (CBCT) images, and (2) to compare these methods for accurate age estimation using regression analysis. Materials and Methods The CBCT images of 200 individuals (102 females and 98 males) were included in the study. The SOS fusion stages and CVM stages were evaluated. The width and length of the clivus were measured. The effects of SOS fusion stages, CVM stages, clivus width, and clivus length on age estimation were evaluated by univariate tests and the effects of coexistence with ANCOVA and regression model. Spearman rank correlation analysis was also used to investigate the relationship between the SOS fusion stage, CVM stage, clivus width, and clivus length. Results The SOS stages, CVM stages, and clivus width were not shown statistically significant differences between the sexes (p-values=0.205, 0.162, and 0.277, respectively), whereas clivus length was significantly longer in males (42.94.26mm) than in females (41.04 +/- 3.74mm). Multiple regression analysis showed 80% success when all parameters (SOS fusion stages, CVM stages, clivus width, and clivus length) were taken into consideration. Conclusion In conclusion, with the use of CVM stages and SOS fusion stages together, an accurate and reliable age estimation can be obtained in forensic medicine.Öğe Observation of the Pulp Chamber of Maxillary First Premolars: A Micro-computed Tomographic Study(Bentham Science Publ Ltd, 2020) Serindere, Gozde; Belgin, Ceren Aktuna; Orhan, KaanBackground: There are a few studies about the evaluation of maxillary first premolars internal structure with micro-computed tomography (micro-CT). The aim of this study was to assess morphological features of the pulp chamber in maxillary first premolar teeth using micro-CT. Methods: Extracted 15 maxillary first premolar teeth were selected from the patients who were in different age groups. The distance between the pulp orifices, the diameter of the pulp and the width of the pulp chamber floor were measured on the micro-CT images with the slice thickness of 13.6 mu m. The number of root canal orifices and the presence of isthmus were evaluated. Results: The mean diameter of orifices was 0.73 mm on the buccal side while it was 0.61 mm on palatinal side. The mean distance between pulp orifices was 2.84 mm. The mean angle between pulp orifices was -21.53 degrees. The mean height of pulp orifices on the buccal side was 4.32 mm while the mean height of pulp orifices on the palatinal side was 3.56 mm. The most observed shape of root canal orifices was flattened ribbon. No isthmus was found in specimens. Conclusion: Minor anatomical structures can be evaluated in more detail with micro-CT. The observation of the pulp cavity was analyzed using micro-CT.Öğe Relationship of the Presence of Lingual Concavity and Mandibular Canal Location: A Retrospective Two-Center Study(2022) Topbas, Nazan Kocak; Özemre, Mehmet Özgür; Uzun, Canan; Gulsahi, Ayse; Orhan, Kaan; Stelt, Paul Van Der; Şeker, OyaAim: To evaluate the possible relationship between the position of the mandibular canal (MC) on digital panoramic images (PI) and the presence of a lingual concavity (LC) on Cone-Beam Computed Tomography (CBCT) scans in two different populations. Materials and methods: In this retrospective study, the digital archives of a private imaging center in Turkey and at The Academic Center for Dentistry Amsterdam (ACTA) in Netherlands patients who had both panoramic and CBCT images, taken between January 2016 and June 2016 due to various indications. A total of 248 patients were assessed. MC position was defined on digital panoramic radiographs; the presence of LC was assessed on CBCT images. In all statistical methods, p value <0.05 was considered statistically significant. The Mc Nemar test and the receiver operating characteristics (ROC) curve analysis (AZ), were performed for data analysis. Results: Considering all patients, the presence of LC was 28% and 31% for the left and right premolar regions and 75% and 77% for the left and right molar regions, respectively. There was no significant difference between right and left sides and between the Turkish and Dutch populations with respect to the presence of LC. Considering all patients, the presence of a LC was higher in the molar region than in the premolar region for both right and left sides with a statistical significance (p<0.001). Conclusions: The higher percentages of LC in the molar region in both populations suggests that a preoperative local CBCT assessment is justified specifically before implant placement in the mandibular molar region. The location of the MC on the PI was not a very strong indication of the presence of a LC.Öğe Three-dimensional evaluation of maxillary sinus volume in different age and sex groups using CBCT(Springer, 2019) Belgin, Ceren Aktuna; Colak, Mehmet; Adiguzel, Ozkan; Akkus, Zeki; Orhan, KaanAim Sinus maxillaris is an important anatomical formation in many branches of dentistry due to its proximity to the field of work. Various methods have been used in literature to measure the maxillary sinus volume (MSV) such as cadavers, stereology, two-dimensional conventional radiographs, computed tomography (CT), magnetic resonance imaging (MRI). The aim of this study is to evaluate the change of maxillary sinus volume according to age and gender with MIMICS 19.0 (Materialise HQ Technologielaan, Leuven, Belgium) which is one of three-dimensional modeling software. Materials and methods This study was performed in 200 patients selected by a retrospective review of the archives of the Dicle University, Faculty of Dentistry, Department of Oral and Maxillofacial Radiology. Patients were divided into five age groups (18-24 years, 25-34 years, 35-44 years, 45-54 years, and >= 55 years) and by sex. Cone-beam computed tomography (CBCT) images of the patients were transferred to the MIMICS software and the MSV was measured. All statistical analyses were performed using the SPSS (Statistical Package for Social Sciences, version 21) software. Results There was no statistically significant difference between the right and left maxillary sinus volume according to the findings obtained from our study, and maxillary sinus volume in males was found to be significantly higher than that of females. Another finding of our study is that the maxillary sinus volume decreases with age increase. Especially it was also found that the sinus volume in males in the 18-24 age group was statistically significantly higher than females. Conclusion Consequently, maxillary sinus volume measurements can be made on CT, CBCT, MRI scans using reconstruction software.
