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 Bibliometric Analysis of 50 Most Cited Articles on Odontomas(Assoc Apoio Pesquisa & Saude Bucal-Apesb, 2020) Serindere, Gozde; Serindere, MehmetObjective: To identify the citation features and review articles on odontomas using bibliometric analysis. Material and Methods: A list of studies about odontoma was obtained by searching using the Scopus database. Abstracts or full texts were read and evaluated. After then, 50 most cited articles were achieved. Studies were categorized as citation numbers, citation density, journal name, article type, the affiliation of the first author and publication year. Descriptive statistics were used to analyze the results. Results: The most frequently cited article received 358 citations, while the least frequently cited article received 42 with a mean of 94.3 citations per article. The mean citation density was 5.13. The study with the highest citation density (12.31) was published in 2006. The highest citation number was found in the 2000s following the 1990s. The 50 most cited articles were published from 1971 to 2011, with 84% (4.2 of 50) published after 1990. USA (n = 9) and Brazil (n = 6) were the two most contributing countries. According to article type, there were eight (16%) review articles. Conclusion: The USA found to have a strong influence on research about odontoma, followed by Brazil. All researches were reported in English, and most of them were published in good quality journals.Öğe Comparison of Head and Neck Cancer Distribution in Turkish and Syrian Populations(Iranian Scientific Society Medical Entomology, 2019) Serindere, Gozde; Bolgul, Behiye; Gursoy, Didar; Hakverdi, Sibel; Savas, NazanBackground: Although oral health improves in several countries, global problems are still present. Predictably, the disadvantaged and poor population groups in both developing and developed countries have high rate of malign disease. The aim of this study was to evaluate the prevalence of head and neck cancers (HNCs) and to compare them between Syrian and Turkish population. Methods: A total of 4570 patients confirmed to have HNC histopathologically from Hatay Mustafa Kemal University Hospital Pathology report archive were retrospectively evaluated. Among them, 452 were Syrian patients while 4118 were Turkish patients. Data were collected from 2010 to 2017. Gender and age information were taken from medical records. According to the pathological results, HNCs were classified. Results: In 474 patients, HNCs were inscriprived, of which 317 were in males and 157 in females aged 23-80 years with histologically approved cancer of head and neck area. Overall, 100 were Syrian patients while 374 were Turkish patients. In both Syrian and Turkish patients, the most observed HNC was squamous cell carcinoma (SCC). Conclusion: Nowadays, the prevalence of cancer is higher because of the excessive consumption of alcohol, tobacco, chewing, and smoking. For the higher cancer incidence in Syrian refugees, we thought that the impact of war such as stress may have been effective as well as the known several etiologic factors of cancer. For the increased risk of cancer, the early diagnosis of this become more important.Öğe A comparison of the accuracy of Willems' and Cameriere's methods based on panoramic radiography(Elsevier Ireland Ltd, 2019) Ozveren, Neslihan; Serindere, Gozde; Meric, Pamir; Cameriere, RobertoTooth development evaluation is majorly the current approach to identify age and maturity. Dental age (DA) is therefore considerably emphasized in forensic and pediatric dentistry. The aim of this study was to assess the applicability of Willems and Cameriere methods for Turkish children. Panoramic images of 636 Turkish healthy children (319 male; 317 female) aged between 6 and 15 years were assessed. DA of the subjects was determined by using Willems and Cameriere methods. The seven right and left permanent lower teeth were valued using these two methods. The mean chronological age (CA) of the subjects was 11.53 +/- 2.25 (min:6, max:14.99) years (boys: 11.29 +/- 2.34 years, girls: 11.77 +/- 2.15 years). Willems method overestimated the CA (p <= 0.001), in contrast, Cameriere method underestimated the CA (p <= 0.001) for both sexes. In different age groups the mean difference between the CA and DA calculated by Cameriere method (CA-DA) ranged from 0.86 to -0.41 years for boys and from 1.00 to -0.21 years for girls, while the mean difference between the CA and DA calculated by Willems method ranged from -0.26 to -0.71 years for boys and from 0.19 to -0.76 years for girls. Cameriere method provided a better percentage of accuracy (84.6% and 77.3% for males and females, respectively) in the absolute difference values within 1 year compared to Willems method. Cameriere method performed slightly better but, both methods may be used for DA estimation in the Turkish population. (C) 2019 Elsevier B.V.

Methods: 20 patients with periapical lesion in the jaw, were included in the study. The presence of expansion or perforation and dimensions of the lesion were performed with CBCT. In the examination of the lesion with USG, shape, echogenicity, vascularization of the lesion and the presence of buccal expansion and perforation, were determined. Subsequently, a biopsy was taken from the lesion for histopathological examination and the final result was compared with the accuracy of the preliminary diagnoses. Results: Kolmogorov-Smirnov test, Wilcoxon test (w) and Cohen's kappa coefficient (kappa) was used to analyze the data. Three of the 4 lesions diagnosed as periapical granuloma as a preliminary diagnosis were confirmed as periapical granuloma in histopathological examination. Periapical cyst was confirmed in histopathological examination of 14 of 16 lesions diagnosed as periapical cyst as a preliminary diagnosis. Mesiodistal (MD) measurements in CBCT measurements were significantly higher than the USG group (p <0.05). There was 100% agreement (p = 0.000) between the evaluation of buccal expansion, buccal perforation, and palatal-lingual perforation between CBCT and USG. Conclusion: It was concluded that the combined use of USG and CBCT can provide the clinician with important information in the diagnosis of periapical lesion.Öğe Cone beam computed tomographic evaluation of infraorbital canal protrusion into the maxillary sinus and its importance for endoscopic surgery(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2022) Serindere, Gozde; Serindere, MehmetObjective: The aim of this retrospective study is to investigate the prevalence of Infraorbital Canal Protrusion (ICP) degree into the maxillary sinus and its relationship with variations in adjacent structures on Cone Beam Computed Tomography (CBCT) images. Methods: 350 CBCT images (700 Infraorbital Canal [IC]) were evaluated retrospectively. ICP was divided into 3 subtypes according to the protrusion degree. The correlation between IC types and variations in adjacent anatomical structures (Haller cell, middle nasal concha pneumatization, maxillary sinus mucosal thickening and septa) was evaluated. The distance between Infraorbital Canal and Cnine Root (IC-CR) was also measured. For type 3, measurements were performed on IC as the length of the bony septum from the IC to the Mxillary Sinus Wall (IC-MSW), the distance from the inferior orbital rim, where the IC begins to protrude into the maxillary sinus (IOR-ICP), the vertical distance from the IC to the Maxillary Sinus Roof (IC-MSR) and Floor (IC-MSF). Results: The prevalence of type 1, 2 and 3 was 62.9%, 29.1%, and 8% respectively. IC-CR was 10.2, 10.7 and 11.4 mm in type 1, 2 and 3, respectively. IC-MSW, IOR-ICP, IC-MSR and floor IC-MSF was 3.8, 10.9, 7.4 and 27.7 mm, respectively. On the right and left side, statistically significant correlation was found between IC types and the presence of the Haller cell and sinus septa. But there was no significant correlation between IC types and middle concha pneumatization. Conclusion: Accurate diagnosis of ICP is very important in preventing infraorbital nerve damage in surgical procedures to be performed in the maxillary region. The results of this study could be a guide for surgical planning in this region. (c) 2022 Associacao Brasileira de Otorrinolaringologia e Cirurgia Cervico-Facial. Published by Elsevier Editora Ltda.

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 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 bone change in smokers and ex-smokers using fractal analysis and lacunarity analysis(Elsevier Science Inc, 2024) Belgin, Ceren Aktuna; Serindere, Gozde; Hammudioglu, Zarif EceObjective: It is known that smoking causes many diseases such as oral and nasopharyngeal cancers, cardiovascular diseases and osteoporosis. With fractal analysis (FA), changes in trabecular bone can be detected. The cavities in the bone can also be evaluated with the lacunarity analysis (LA). In the light of this information, the aim of this study is to investigate how the duration of smoking and the duration of smoking cessation affect bone change in the mandible using FA and LA. Methods: Panoramic radiographs (PR) of 140 patients were grouped according to the duration of smoking and the duration of smoking cessation. The changes in the mandibular bone were evaluated with both FA and LA, and the results were compared with the control group who never smoked. Kolmogorov-Smirnov test, Mann -Whitney U test and Spearman correlation analysis was used in the analysis. Results: The smokers ' FA value was significantly lower than the control group and the ex -smokers group. The smokers ' LA value was significantly higher than the control and ex -smokers ' group. The ex -smokers ' FA value was significantly lower than the control group. Both FA and LA values did not differ significantly between the genders. No significant correlation was observed between both FA and LA values and age. Conclusions: FA values were lower and LA values were higher in smokers. It is thought that in smokers, the trabeculation in the bone decreases and accordingly the intraosseous spaces increase, and the duration of smoking and quitting also affects the internal structure of the bone. PR can be used to evaluate bone structure with FA and LA analysis.Öğe Evaluation of canalis sinuosus and accessory canal morphology by cone-beam computed tomography(Springer, 2024) Belgin, Ceren Aktuna; Serindere, Gozde; Hammudioglu, Zarif Ece; Kucuk, MerveObjectiveTo evaluate canalis sinuosus (CS) and accessory canalis sinuosus (AC) morphology and their relationship with the impacted canine on cone-beam computed tomography (CBCT) images.MethodsThe diameter and location of the CS, its distance from the nasal cavity (NC-CS), its distance from the buccal cortical plate (BC-CS), and its distance from the alveolar ridge crest (AR-CS) were evaluated on 1000 CBCT scans. The prevalence and termination of AC and the presence of impacted canines were also evaluated.ResultsCS was detected in 89 (8.9%) of 1000 CBCTs. The mean CS diameter was found as 1.34 +/- 0.53 mm. No statistically significant difference was found between gender, age, direction, and CS presence and diameter. CS was most frequently seen in regions 11 (23.6%) and 13 (23.6%). The average NC-CS, BC-CS, and AR-CS length was 6.14, 6.06 and 4.35 mm, respectively. AC was detected in 22 patients (24.71%). There was no statistically significant difference between the presence of AC and gender, age, CS diameter, NC-CS, BC-CS, and AR-CS distance. BC-CS length and AR-CS length were statistically significantly higher in patients with impacted canines.ConclusionsIt should be kept in mind that the CS diameter, NC-CS, BC-CS, and AR-CS distance may increase in the presence of an impacted canine and the integrity of the neurovascular structure should be preserved. The fact that the CS is often localized in the palatial region requires a detailed evaluation of the anterior maxillary region with three-dimensional imaging methods.Öğe Evaluation of maxillary palatal process pneumatization by cone-beam computed tomography(Elsevier, 2023) Serindere, Gozde; Serindere, Mehmet; Gunduz, KaanPurpose: The aim of this study is to investigate the pneumatization type of the palatal process (PTP) and angular and distance measurements of neighbouring structures on cone beam computed tomography (CBCT) images. Materials and Methods: 400 maxillary sinuses (MS) of 200 patients (96 female; 104 male; mean age: 43.2) were retrospectively evaluated. PTP was divided into three as types 1,2 and 3 and evaluated at distances 4, 8, 16, and 24 mm posterior to incisive foramen. The sinus and alveolar ridge height, palatonasal recess angle (PRA) and palatal junction angle (PJA) were also measured and recorded. Results: PTP I (101, 25.3%) was the most frequent type, followed by PTP II (95, 23.8%), and the least was PTP III (4, 1%). In patients with PTP I, the alveolar ridge height in the 4 mm and 8 mm group was significantly higher than in the patients with PTP II and III (p<0.05). In patients with PTP I, PRA in the 4 mm and 16 mm groups was significantly higher than in patients with PTP II and III (p<0.05). Sinus and alveolar ridge height, PRA and PJA did not differ significantly between the right and left sides in the 4 mm, 8 mm, 16 mm, and 24 mm groups (p>0.05). Conclusion: Knowing the anatomy of the MS is very important fora successful surgical procedure in this area. Anatomy and pathology of the MS can be understood more clearly in CBCT.

Materials and Methods: A CNN model, which is an artificial intelligence method, was utilized. The model was trained and tested by applying 5-fold cross-validation to a dataset of 148 healthy and 148 inflamed sinus images. The CNN model was implemented using the PyTorch library of the Python programming language. A receiver operating characteristic curve was plotted, and the area under the curve, accuracy, sensitivity, specificity, positive predictive value, and negative predictive values for both imaging techniques were calculated to evaluate the model. Results: The average accuracy, sensitivity, and specificity of the model in diagnosing sinusitis from PRs were 75.7%, 75.7%, and 75.7%, respectively. The accuracy, sensitivity, and specificity of the deep-learning system in diagnosing sinusitis from CBCT images were 99.7%, 100%, and 99.3%, respectively. Conclusion: The diagnostic performance of the CNN for maxillary sinusitis from PRs was moderately high, whereas it was clearly higher with CBCT images. Three-dimensional images are accepted as the gold standard for diagnosis; therefore, this was not an unexpected result. Based on these results, deep-learning systems could be used as an effective guide in assisting with diagnoses, especially for less experienced practitioners.Öğe Evaluation of morphological variations of petrotympanic fissure using computed tomography imaging of the temporal bone(Elsevier, 2022) Serindere, Mehmet; Serindere, Gozde; Gunduz, Kaan; Kopuz, CemPurpose: Petrotympanic fissure (PF) is important for both dentists and otolaryngologists to know the tempo-ral anatomy well especially for pre-surgical radiological evaluations. Computed tomography (CT) is indis-pensable method for temporal bone imaging. The purpose of this study was to evaluate PF morphology and position using CT. Methods: CT scans of 300 patients (600 PFs) were retrospectively evaluated. PF types were recorded by divid-ing into 3 groups (Type 1,2 and 3). Length of the mandibular fossa (MF) and PF, vertical diameter (VD) of the PF at the MF level, midpoint and tympanic cavity (TC) level were measured. PF position types were subdi-vided as low, midline and high. Results: Type 1, 2 and 3 was found in 18.7%, 51.5% and 29.8% of the cases, respectively. The mean length of the MF and PF was 18.33 mm and 3.77 mm, respectively. The mean VD of the PF at the MF level, midpoint and TC level was 1.71, 0.98 and 0.97 mm, respectively. The low, midline and high position of PF was observed 14.5%, 54.3% and 31.2% of the cases, respectively. Conclusion: Length of the MF and PF in males was significantly higher than females. VD of the PF at the MF level in Type 1 and Type 3 was significantly higher than type 2. In type 1,VD of the PF at the midpoint was sig-nificantly higher than type 2 and type 3. VD of the PF at the TC level in Type 1 and Type 3 was significantly higher than type 2. (c) 2022 Elsevier Masson SAS.

Evaluating the age and main complaints of children is therefore important during their first dental visit (FDV). The purposes of this study were to determine the age, reason for the visit, behavioral response, and caries status at the FDV and to evaluate the factors affecting these parameters. Parents of 325 pediatric patients (159 males; 166 females; mean age 7.20 +/- 2.78 years) at their FDV were asked to fill out a questionnaire requesting sociodemographic information and their child's medical history, brushing habits, and reasons for attending dental consultation. The decayed-missing-filled-teeth ( dmft/DMFT) scores were also recorded. The child's behavioral responses during the FDV were evaluated according to Frankl's Behavior Rating Scale (FBRS). Higher maternal education level and dmft/DMFT score were associated with earlier FDV age. The most common reason for the FDV was dental caries in 33.5% of patients, followed by toothache (29.5%). Most of the children showed positive behavior (46.7%), with positive behavior affected by age and negative behavior affected by the dmft/DMFT score and distance from home. The mean dmft/DMFT score was 8.1 +/- 4.4 and was negatively affected by toothbrushing frequency and family income. These study results indicate that Turkish children living in Edirne present at a late age for the FDV. Raising awareness in terms of dental health care among parents is important to ensure that children attend their FDV at an early age.Öğe An evaluation of the relationship between maxillary sinus anterior wall depression and maxillary sinus opacity by computed tomography and panoramic radiography(Springer, 2020) Serindere, Gozde; Belgin, Ceren AktunaObjective Maxillary sinus anterior wall depression (AWD) has been associated with patterns such as the presence of panoramic innominate line and silent sinus syndrome. The aim of this study was to evaluate the relationship between AWD of maxillary sinus and both maxillary sinus opacity and the presence of innominate line using computed tomography (CT) and panoramic radiography (PR). Materials and methods 250 CT and PR images (122 female, 128male) which had been taken for various reasons were randomly selected from the radiology archive of the our department. Innominate line visibility in PR is divided into three as invisible, obscure and clear. On CT images, the distance between guide line and the deepest point of the maxillary sinus anterior wall was calculated as AWD. The presence of maxillary sinus opacity and maxillary sinus AWD were evaluated on CT images. Demographic information such as age, gender and localization of the findings were noted in all measurements. Results In 143 (57.2%) patients, the innominate line (clear and obscure patterns) was seen on the PR images. AWD was observed in 104 (41.6%) CT images. The presence of maxillary sinus opacity was observed in 117 (46.8%) images. The mean right anterior wall depth was 5.69 and 4.88 in males and females, respectively, while the mean left anterior wall depth was 5.64 and 4.94 in males and females, respectively. Right wall depth was significantly higher in males (p < 0.05).There was no statistically significant difference in left wall depth (p > 0.05). Conclusions Anterior wall depression was found to be associated with both maxillary sinus opacity and the visibility of the innominate line. Patients with AWD should be considered as susceptible to maxillary sinus diseases.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 trabecular bone changes in patients with periodontitis using fractal analysis: A periapical radiography study(Wiley, 2020) Belgin, Ceren Aktuna; Serindere, GozdeBackground The present study was aimed to evaluate the trabecular bone changes between healthy individuals and periodontitis patients with fractal dimension analysis on digital periapical radiographs. Methods Data from 35 healthy and 35 individuals with periodontitis were confirmed from the database of our faculty and included in the study. Two regions of interest (ROI) were selected belonging to mesial and distal region of mandibular first molar on periapical radiographs. The mean fractal dimension (FD) values of two regions were calculated with using box-counting method. Student t test was used for the comparison of the FDs. Results The mean FD of individuals with periodontitis was 0.97, whereas it was 1.04 for the healthy group. The mean FD values were significantly higher in the healthy group (P < 0.05). In the periodontitis group, as the FD of mesial interdental bone increased, the FD of distal interdental bone increased significantly (P < 0.05). Conclusion Because of FD numerically showing changes in bone trabeculation, changes in the alveolar bone can be detected quantitatively.Öğe Fractal and radiomorphometric analysis of mandibular bone changes in patients undergoing intravenous corticosteroid therapy(Elsevier Science Inc, 2020) Belgin, Ceren Aktuna; Serindere, GozdeObjective. To evaluate mandibular bone changes by comparing the fractal dimension (FD), mandibular cortical width (MCW), and panoramic mandibular index (PMI) on panoramic radiographs in patients using intravenous corticosteroids versus controls. Study Design. In total, 60 patients were divided into 2 groups: 30 patients receiving intravenous corticosteroid treatment and 30 age- and sex-matched healthy people as the control group. Panoramic radiographs of all patients were evaluated. FD was measured in 4 regions: the subcortical area in the condyle, the area superior to the angle of the mandible, the alveolar bone distal to the mandibular left second premolar root, and the alveolar bone mesial to the mental foramen. MCW and PMI were calculated to assess cortical thickness. Results. The FD values in the condyle, angle of the mandible, and mental foramen region were significantly lower in the corticosteroid group (P <= .011), but there was no significant difference in the second premolar area (P = .101). MCW values were significantly lower in the corticosteroid group (P < .001). There was no significant difference in PMI between the groups (P = .544). Conclusions. The FD and MCW values of the patients using corticosteroids can be helpful in quantitatively and objectively evaluating osseous changes in patients receiving intravenous corticosteroids.Öğe Gingival Enlargement in Patients who Have Undergone Renal Transplants: A Meta-Analysis(Univ Indonesia, Fac Dentistry, 2018) Serindere, Gozde; Ozveren, NeslihanSevere gingival enlargement (GE) is one of the most commonly observed adverse effects in patients who have undergone renal transplants due to the use of cyclosporine A. Objectives: We aimed to gain more insight into the prevalence of GE in patients with renal transplants. Methods: We searched the PubMed and Web of Science databases for relevant studies from January 1990 to January 2018. Using random effects models, we calculated summary incidence rates and 95% confidence intervals (CIs). Results: A total of 595 patients from 10 studies were included. Patients using cyclosporine A with or without any other drugs had a 62.6% (95% CI, 41.9%-79.5%) incidence of GE. Subgroup analysis according to diagnostic criteria showed that the incidence of GE was lower when using well-defined diagnostic criteria or scoring system. The incidence of GE was 88.2% (95% CI, 80.9%-93.0%) in patients using cyclosporine A with nifedipine. Cyclosporine A without nifedipine was associated with a significantly decreased risk of GE incidence when compared with the combination of cyclosporine A and nifedipine (odds ratio: 0.198; 95% CI, 0.083-0.473; P < 0.001). Conclusions: It is important for all clinicians to know the effects of the aforementioned drugs and the treatment options.
