Objectives: The aim of this study was to compare leukocyte and platelet-rich fibrin (L-PRF) and photobiomodulation (PBM) applications, which have been repeatedly reported to be superior to control groups, in terms of pain, soft tissue and bone healing in tooth extraction sockets.
Materials And Methods: This double-blind, randomized clinical study was completed with 34 patients, who had an indication for extraction of their bilaterally impacted teeth. The right and left teeth of the patients were randomly divided into L-PRF and PBM groups.
Objective: The aim of this study is to determine the age-based prevalence of dens invaginatus cases and to learn the radiologic findings. In addition, fractal analysis of the periapical regions of unilateral dens invaginatus cases and contralateral teeth was performed to determine the effect of possible microleakage on fractal dimension.
Methods: A total of 136 patients (170 teeth) identified in panoramic radiographs taken for diagnostic purposes between January 2018 and December 2023 at our Department of Oral and Maxillofacial Radiology were included in the study.
Temporary anchorage devices (TADs) are frequently applied to different anatomic areas with different protocols to increase skeletal effects and anchorage in orthodontic treatment planning. It has been reported in many literatures that primary stability for orthodontic TADs is significant for long-term survival rate. For this reason, different areas of the palatal region, which has many indications, have been widely used in the studies.

Methods: This is an institutional and retrospective cohort study of patients who presented for evaluation of cone beam computed tomography (CBCT) between 2019 and 2020.
Objectives: This study aimed to analyze the association between the use of proton pump inhibitors (PPIs) and radiomorphometric parameters of trabecular and cortical bone of the mandible.
Methods: A total of 64 patients (37 females and 27 males) using PPIs (PPI group) and 64 age- and gender-matched healthy individuals (control group) were included in this study. The analyzed radiomorphometric parameters were fractal dimension (FD), mandibular cortical width (MCW), and mandibular cortical index (MCI).
Objectives: This study aimed to estimate the dental age (DA) using the London Atlas, Willems, and Nolla methods and to compare their accuracies.
Methods: The DA was estimated using the aforementioned methods on panoramic radiograms of a total of 919 Eastern Turkish patients aged 6-14 years, of whom 459 were female and 460 were male. The overestimation and underestimation values were determined in relation to the chronological age (CA) values.
Purpose: The aim of this study was to determine the prevalence of canine transmigration in the maxilla and mandible and to perform a 3-dimensional examination of impacted canines (ICs) on cone-beam computed tomography (CBCT) images.
Materials And Methods: CBCT images of 35 transmigrated and 35 nontransmigrated canines (control group) were analyzed. Associations between gender, jaw, dental anomalies associated with ICs, adjacent lateral status, the status of deciduous canine, contact of the apical region with the cortex, contact of the crown with the cortex, canine location, resorption of adjacent teeth and severity, periodontal contour of adjacent teeth, odontoma, root status of the canine, cyst formation, and age groups of patients with transmigration were evaluated.
Objectives: The purpose of this study was to evaluate the effect of section thickness on volume estimations of bone defects scanned using cone beam computed tomography (CBCT).
Methods: 25 bone defects were prepared on sheep mandibles and scanned using a KaVo 3D eXam (KaVo Dental, Biberach, Germany) CBCT device. Section thickness of images were reconstructed at 0.
Purpose: The study examined the association between mastoid pneumatization (MP) volume and the existence of foramen Huschke (FH).
Methods: Cone beam computed tomography (CBCT) images of 1117 patients (2234 mastoid regions) were analyzed. The prevalence of FH was calculated.
Purpose: Impacted third molars (M3s) may lead to external root resorption (ERR) and dental caries (DC) in the adjacent second molars (M2s). The aim of this study was to identify the risk factors for ERR and DC in M2s associated with impacted M3s.
Materials And Methods: We implemented a cross-sectional study and enrolled a sample composed of patients with M3s and M2s present and cone-beam computed tomography (CBCT) scans available for review.
Purpose: The purpose of this study was to compare the accuracy of the planimetric methods on volume estimations by using cone beam computed tomography (CBCT).
Materials And Methods: Thirty-one prepared intraosseous bone defects from thirteen bovine femur condyles were scanned with CBCT. The defect volumes were estimated by point counting (PC), manual segmentation (MS) and semiautomatic segmentation (SAS) methods at 0.
Objectives: Our study aimed to determine the prevalence and volumetric estimates of Stafne bone cavities (SBC) on cone beam computed tomography (CBCT) images.
Methods: This retrospective study, which involved the CBCT images of 1141 men and 1260 women with an age range of 10-90 years, aimed to determine the prevalence of SBCs and to calculate their volumes using the semi-automatic segmentation method.
Results: A total of 15 SBCs were diagnosed in 14 patients.
