    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, Roberto
    Tooth 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. All rights reserved.

    Evaluation of maxillary sinusitis from panoramic radiographs and cone-beam computed tomographic images using a convolutional neural network
    (Korean Acad Oral & Maxillofacial Radiology, 2022) Serindere, Gozde; Bilgili, Ersen; Yesil, Cagri; Ozveren, Neslihan
    Purpose: This study developed a convolutional neural network (CNN) model to diagnose maxillary sinusitis on panoramic radiographs (PRs) and cone-beam computed tomographic (CBCT) images and evaluated its performance. 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.

    Evaluation of Pediatric Patient's Age, Behaviors, and Reasons for the First Dental Visit in Edirne, Turkey: a Cross-Sectional Study
    (Univ Costa Rica, Fac Odontologia, 2021) Ozveren, Neslihan; Serindere, Gozde; Baltaci, Ezgi
    Oral and dental health are vital parts of general baby health, and early dental visits provide significant prevention-focused intervention and parental counseling regarding oral health. 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.

    Evaluation of third molar agenesis associated with hypodontia and oligodontia in turkish pediatric patients
    (Istanbul Univ Press, Istanbul Univ Rectorate, 2020) Atay, Meltem Tekbas; Ozveren, Neslihan; Serindere, Gozde
    Purpose To evaluate the association between third molar (M3) agenesis and hypodontia and oligodontia in pediatric patients by using panoramic radiography. Materials and Methods Panoramic radiographs of 1,471 patients (899 females; 572 males) and 5,884 teeth were retrospectively evaluated. The age and gender of the patients were recorded. Patients ages 9-15 years old were included in the study. The mean age was 12.76. The agenesis of M3 teeth and the relationship between M3 agenesis and hypodontia and oligodontia were recorded according to findings from the upper and lower jaw, in both the right and left locations, along with the number of M3 with agenesis. Data were analyzed using chi-square and McNemar tests (p<0.05). Results A total of 1,319 (89.7%) patients had all M3 teeth present in the mouth, while the other 152 (10.3%) had congenital agenesis in one or more teeth. The number of teeth in which M3 agenesis was seen, in order of the number of missing M3 teeth, the percentages were 2.6% for one, 2.4% for two, 1.0% for three and 4.3% for four missing teeth.Hypodontia was detected in 37 patients and oligodontia was detected in 3 patients. Conclusion The prevalence of M3 agenesis varies from one population to another. Two of the dental anomalies associated with M3 agenesis are hypodontia and oligodontia. In this study, M3 agenesis varied in terms of region and gender; hypodontia was also significantly higher in patients with missing mandibular M3.

    Gingival Enlargement in Patients who Have Undergone Renal Transplants: A Meta-Analysis
    (Univ Indonesia, Fac Dentistry, 2018) Serindere, Gozde; Ozveren, Neslihan
    Severe 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.
