Çocukların doğru ve yeterli beslenebilmeleri ile büyümegelişimlerinin devamı için, sağlıklı bir ağız yapısına sahip olmaları gerekmektedir. Bunun için de diş çürükleri ve diş kayıplarının en aza indirilmesine ihtiyaç vardır. Büyüme ve gelişim dönemindeki çocuklarda, daimi dişlenmeye geçiş sürecinde en fazla etkilenen dişler daimi birinci büyük azı dişleridir. Ebeveynlerin büyük bir kısmı, bu dişlerin daimi diş olduğunun farkında değildirler. Ancak, koruyucu ve tedavi edici yöntemlerin uygulanabilmesi için düzenli diş hekimi kontrolü, oral sağlık idamesi ve farkındalık çok önemlidir. Bu makalede daimi birinci büyük azı dişlerinin önemi vurgulanmaktır. Başlık (İngilizce): IMPORTANCE AND EVALUATION OF PERMANENT FIRST MOLAR TEETH FOR CHILDREN IN 6-12 AGE GROUP-REWİEV Öz (İngilizce): In addition to therapeutic applications, one of the primary objectives of Pediatric Dentistry is to ensure the establishment and the implementation of preventive dentistry. For proper and adequate nutrition and continuing growth & development of children, it is necessary to have a healthy mouth structure. So, dental caries and tooth loss should be minimized. The most affected-teeth are permanent first molars throughout the transition to the permanent dentition during children?s growth and development phase. A large number of parents are not aware that these are permanent teeth. However, regular dental visits and maintaining oral health and oral awareness are very important for the implementation of preventive and curative methods. The importance of permanent first molars is highlighted in this article.Öğe Accuracy of age estimation with Demirjian and Nolla methods in Eastern Turkish children aged 3-17 years old(Istanbul Univ Press, Istanbul Univ Rectorate, 2022) Duruk, Gulsum; Ozdal, Tamara Pelin Gundogdu; Duman, SacidePurpose Dental age assessment is one of the most reliable methods of chronological age estimation used for criminal, forensic and anthropologic purposes. This study aimed to determine how accurate it was to estimate the chronological age by looking at the dental age measured with the Nolla and Demirjian methods in a Turkish sample, based on the variables of gender and age-group. Materials and Methods A retrospective study was performed on panoramic radiographs of 1587 subjects (774 females and 813 males), aged 3-17 years. The mean dental age according to the Demirjian and Nolla methods were compared to the mean chronological age (CA). Also, the percentage value of prediction of CA was determined by using the both methods. Results An under-estimation of the chronological age was observed by using Nolla's method (males-0.003, females-0.32, both-0.16) and an over-estimation of the dental age was observed by using Demirjian's method (males 0.61, females 0.75, both 0.68). Conclusion Nolla's method was more accurate in the CA estimation than Demirjian's method in Eastern Turkish population.Öğe Automated Mesiodens Detection with Deep-Learning-Based System Using Cone-Beam Computed Tomography Images(Wiley-Hindawi, 2023) Syed, Ali Zakir; Ozen, Duygu Celik; Abdelkarim, Ahmed Z.; Duman, Suayip Burak; Bayrakdar, Ibrahim Sevki; Duman, Sacide; Celik, OzerThe detection of mesiodens supernumerary teeth is crucial for appropriate diagnosis and treatment. The study aimed to develop a convolutional neural network (CNN)-based model to automatically detect mesiodens in cone-beam computed tomography images. A datatest of anonymized 851 axial slices of 106 patients' cone-beam images was used to process the artificial intelligence system for the detection and segmentation of mesiodens. The CNN model achieved high performance in mesiodens segmentation with sensitivity, precision, and F1 scores of 1, 0.9072, and 0.9513, respectively. The area under the curve (AUC) was 0.9147, indicating the model's robustness. The proposed model showed promising potential for the automated detection of mesiodens, providing valuable assistance to dentists in accurate diagnosis.Öğe The caries impacts and experiences questionnaire for Turkish children by age groups'(Bmc, 2023) Duman, Sacide; Inceoglu, FeyzaBackground The Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) assess children's effects of dental caries on their quality of life. This study aimed to determine the scale's Turkish version (CARIES-QC/T) validity and reliability according to age groups and to create the scale that is specific to selected age groups.Methods Children were divided up into 3 age groups (5-7, 8-10 and 11-14 ages). Explanatory factor analysis (EFA) was used in the concept validation process. Confirmatory factor analysis (CFA) was used for cross-cultural validity. For each group, test-retest analyses were performed on 20 children. Inter-question correlation and Cronbach's alpha were used to examine internal consistency.Results A total of 360 children (mean age; 9.04, 56.1% girls,) 120 children in each group, participated in the study. Questions 7 and 12 for the 5-7 age group, Questions 4 and 7 for the 8-10 and 11-14 age groups were excluded from the analysis (according to EFA results; factor loads < 0.30). Three modified CARIES-QC/T scales structures with a total of 10 questions were developed for the age groups of 5-7, 8-10, and 11-14.Conclusions Some questions on the Caries-QC/T scale should be eliminated, it was found when it was evaluated for age specificity. Although the results of the Caries-QC scale studies to be carried out in different societies and age groups vary, the high sample size in this study and the statistically strong results showed that the Caries-QC/T scale forms that we adapted could be used by the specified age groups.Öğe Çocuklarda Yeşil Çay Kullanımının Dental ve Periodontal Sağlığa Etkileri(2022) Vural, Handan; Duman, SacideDiş çürüğü ve periodontal hastalıkların önlenmesinde öncelikle iyi oral hijyen gereklidir.

Materials and methods: CBCT images of 53CL/P patients (28 males and 25 females) and a control group of 76 patients (42 males and 34 females) were evaluated. Retrospectively, 258 temporal bone images from 129 patients were evaluated in terms of SSCC morphology and divided into a normal pattern (0.6-1.7mm in thickness), a papyraceous pattern (<0.5mm), a thick pattern (>1.8mm), a pneumatized pattern and dehiscent. The chi-squared test was used to compare differences among semicircular canal dehiscence (SSCD) patterns in the CL/P and control groups; p <.05 was taken to reflect statistical significance. Results: The characteristics of the SSCC were evaluated on CBCT images in patients with CL/P and controls. In total, 158 (61%) cases were normal (0.6-1.7mm in thickness), 31 (12%) papyraceous (<0.5 mm), 8 (3%) thick, and 34 (13%) pneumatized. SSCD was observed in 27 (11%) cases. Statistically significant differences between the CL/P and control groups were evident in terms of SSCC morphology (p<.001). Conclusions: SSCD should be considered if a CL/P patient exhibits a vestibular system deficiency. Oral and maxillofacial radiologists should pay attention to SSCD when interpreting CBCT images. Future studies should use high-level spatial resolution CBCT to focus on cleft site and SSCC morphology in larger patient populations.Öğe Cone-beam computed tomography evaluation of C-shape canals and longitudinal grooves of mandibular first and second molar teeth(2019) Duman, Şuayip B.; Duman, Sacide; Bayrakdar, İbrahim S.; Yasa, Yasin; Gumussoy, IsmailAbstract: Aim: This study aims to evaluate the anatomical features and prevalence of C-shaped roots and longitudinal grooves in mandibularfirst and second permanent teeth using cone-beam computed tomography (CBCT).Material and Methods: CBCT records of first and second mandibular teeth from 839 patients who applied to the Department of Oraland Maxillofacial Radiology between 2011 and 2018 were used.

The purpose of the study is to develop and evaluate the function of CNN-based AI model to diagnose teeth with taurodontism in panoramic radiography. Methods 434 anonymized, mixed-sized panoramic radiography images over the age of 13 years were used to develop automatic taurodont tooth segmentation models using a Pytorch implemented U-Net model. Datasets were split into train, validation, and test groups of both normal and masked images. The data augmentation method was applied to images of trainings and validation groups with vertical flip images, horizontal flip images, and both flip images. The Confusion Matrix was used to determine the model performance. Results Among the 43 test group images with 126 labels, there were 109 true positives, 29 false positives, and 17 false negatives. The sensitivity, precision, and F1-score values of taurodont tooth segmentation were 0.8650, 0.7898, and 0.8257, respectively. Conclusions CNN's ability to identify taurodontism produced almost identical results to the labeled training data, and the CNN system achieved close to the expert level results in its ability to detect the taurodontism of teeth.Öğe Detecting white spot lesions on post-orthodontic oral photographs using deep learning based on the YOLOv5x algorithm: a pilot study(Bmc, 2024) Ozsunkar, Pelin Senem; Ozen, Duygu CelIk; Abdelkarim, Ahmed Z.; Duman, Sacide; Ugurlu, Mehmet; Demir, Mehmet Ridvan; Kuleli, BatuhanBackground Deep learning model trained on a large image dataset, can be used to detect and discriminate targets with similar but not identical appearances. The aim of this study is to evaluate the post-training performance of the CNN-based YOLOv5x algorithm in the detection of white spot lesions in post-orthodontic oral photographs using the limited data available and to make a preliminary study for fully automated models that can be clinically integrated in the future.Methods A total of 435 images in JPG format were uploaded into the CranioCatch labeling software and labeled white spot lesions. The labeled images were resized to 640 x 320 while maintaining their aspect ratio before model training. The labeled images were randomly divided into three groups (Training:349 images (1589 labels), Validation:43 images (181 labels), Test:43 images (215 labels)). YOLOv5x algorithm was used to perform deep learning. The segmentation performance of the tested model was visualized and analyzed using ROC analysis and a confusion matrix. True Positive (TP), False Positive (FP), and False Negative (FN) values were determined.Results Among the test group images, there were 133 TPs, 36 FPs, and 82 FNs. The model's performance metrics include precision, recall, and F1 score values of detecting white spot lesions were 0.786, 0.618, and 0.692. The AUC value obtained from the ROC analysis was 0.712. The mAP value obtained from the Precision-Recall curve graph was 0.425.Conclusions The model's accuracy and sensitivity in detecting white spot lesions remained lower than expected for practical application, but is a promising and acceptable detection rate compared to previous study. The current study provides a preliminary insight to further improved by increasing the dataset for training, and applying modifications to the deep learning algorithm.Clinical revelance Deep learning systems can help clinicians to distinguish white spot lesions that may be missed during visual inspection.Öğe Determining the Knowledge Level of Parents about Their Children’s Rational Drug Use(2021) Duman, SacideThe main responsibility for the rational use of drugs (RUD) in children belongs to the parents. The aim of this study was to determine the knowledge and awareness level of parents about RUD in children. The study included literate volunteer parents with no learning disability. The rational drug use scale (RDUS), developed by Demirtas, was modified to assess parents' knowledge about RUD in children (higher score indicates higher knowledge level). Questionnaires for which all questions were not answered were excluded from the study. Two-group differences (gender, employment status, health insurance) were compared using the Mann-Whitney U test. Kruskal Wallis test was used to compare the differences among three or more groups (age: ?30, 30-40 and >40 years; education level: elementary, high school, associate degree and bachelor degree or higher; income: <2000 TL, 2000-5000TL and >5000 TL; number of children: 1, 2, 3 and ?4). The study included 410 participants (mean age: 35±8.2; female: 58.3%). The mean scores obtained from the scale was 21.31 ± 4.1. Among females, the knowledge of RUD varied across education level (X2=32.333, p<0.001), income class (X2=16.096, p<0.001) and the number of children (X2=7.868, p=0.049). RDUS score was higher in employed females compared to non-employed females (U=2337.5, p<0.001). In male participants, the knowledge of RUD varied across education level (X2=32.130, p<0.001), income class (X2=16.893, p<0.001) and the number of children (X2=8.307, p=0.040). It was concluded that parents displayed incorrect attitudes and behavours regarding the use of drugs for in children.Öğe Evaluation of impacted canines' localization and adjacent lateral incisors' root resorption with orthopantomography and cone-beam computed tomography(Springer, 2021) Akkuc, Sibel; Duruk, Gulsum; Duman, SacideObjectives In this retrospective study, the frequency and severity of ectopic eruption in the children's permanent canines, changes between the impacted canine parameters on orthopantomography (OPG) taken for routine follow-up were demonstrated. Also, it was aimed to reveal the differences between OPG and cone beam computed tomography (CBCT). Methods Ten thousand (5020 girls, 4980 boys) pediatric patient, were retrospectively investigated for the presence of impacted canine radiographically. OPG and CBCT images of 343 pediatric patients (207 girls, 136 boys) detected impacted canines (n = 432) were evaluated in four steps that the angular and linear measurement, position and status relationships with adjacent anatomical structures were investigated. Results The incidence of impacted canine in children was 3.43% (4.02% girls, 2.73% boys). The percentage of adjacent lateral incisor' resorption was 33%. Although the presence of resorption in lateral incisors in contact with a canine was found to be statistically significant (p = 0.02), there was no statistically significant relationship the follicle size and localization of canine in the transverse plane. When images were compared, it was found that there was a statistically significant difference between CBCT and OPG about the parameter of canine angulation to the midline and parameter of canine angulation to the lateral incisor. Conclusions Pediatric dentists should prefer OPG as the first choice for radiographic imaging for the diagnosis of impacted canine at an early age. Follow-up OPGs should be carefully studied with advancing age. The CBCT should be preferred to prevent complications, to view its relationship with adjacent anatomical structures and canine localization in detail.Öğe Evaluation of radix entomolaris in mandibular first and second molars using cone-beam computed tomography and review of the literature(Springer, 2020) Duman, Suayip Burak; Duman, Sacide; Bayrakdar, Ibrahim Sevki; Yasa, Yasin; Gumussoy, IsmailObjectives The aim of the present study is to identify the prevalence of radix entomolaris in mandibular first and second molars and to determine morphological classifications and associations with other root and canals. Methods Mandibular first and second molar teeth of 850 Turkish patients were evaluated using cone-beam computed tomography. A total of 2800 mandibular first molars and second molars were screened. The CBCT examination was performed at five different axial levels. The prevalence of total radix entomolaris, unilateral-bilateral, right-left side and gender distributions, and the classification of radix entomolaris's canal configurations were measured. Results Radix entomolaris was found in 2.9% (n = 25) of the patients and 1.2% (n = 34) of the teeth. The prevalence of radix entomolaris in mandibular first molars was higher than in mandibular second molars (p < 0.01), in males than in females (p < 0.05) and in right side than left side. An additional tubercle was found in 23% of the teeth with radix entomolaris. For buccolingual orientation, Type A canal variation was the highest and Type C canal variation was the lowest. Regarding locations of cervical parts, Type III canal variation was the highest while Type I canal variation was the lowest. Conclusions The prevalence of radix entomolaris was lower in the Turkish population than in other Asian populations but, in multiethnic societies, it needs attention. Before starting endodontic treatment, the clinician should examine the radiography thoroughly and apply advanced radiography methods when necessary. Cone-beam computed tomography is a valuable advanced radiography method for assessing such anatomical variations in vivo.Öğe Evaluation of radix entomolaris in mandibular first and second molars using cone-beam computed tomography and review of the literature (vol 36, pg 320, 2020)(Springer, 2022) Duman, Suayip Burak; Duman, Sacide; Bayrakdar, Ibrahim Sevki; Yasa, Yasin; Gumussoy, Ismail[Abstract Not Available]Öğe The evaluation of the clinical and radiographic records of the first molar teeth in pediatric patients(2019) Duman, Sacide; Duruk, GulsumAim: This study aimed to determine the status, the need for treatment, and the performed treatments in the first permanent molars, together with the general health status, in pediatric patients. Material and Methods: A total of 5996 teeth from 1499 children were included in the study. The first permanent molars were evaluated by panoramic radiography and patient recording system. The teeth were classified according to the following data: age, gender, jaw, side, teeth requiring therapy, preventive and interventional implementations.Results: It was determined that 45.7% of the first permanent molars were healthy and 54.3% were necessitating treatment. The rate of the healthy teeth was determined to decrease with increasing age (p0.001). The rate of healthy teeth in boys was higher than girls and the healthy teeth in maxilla were higher than mandible (p0.001). Applications for preventive treatment were most frequently performed between group 1 (p0.001). Preventive treatments were performed higher in boys than girls (p0.001). Mean age of first restorative treatment, endodontic treatment and extraction on first permanent molars were 10 years 7 months 18 days, 11 years 1 month 8 days and 11 years 5 months 13 days, respectively.Conclusion: Since the awareness of the families on the first permanent molars, which are among the first erupted permanent teeth, is low, and the oral hygiene of children is inadequate, caries and tooth loss are encountered very frequently in these teeth. In spite of developing dentistry technologies and ease of access, dental health is very dramatic in developing countries.Öğe The evaluation of the clinical and radiographic records of the first molar teeth in pediatric patients(2019) Duman, Sacide; Duruk, GülsümAbstract: Aim: This study aimed to determine the status, the need for treatment, and the performed treatments in the first permanent molars, together with the general health status, in pediatric patients.

Methods Patients were evaluated by pedodontists to identify dental, skeletal, and functional malocclusion (n = 240; <15 years). In order to determine the sleep and daytime behavior of the patients, pediatric sleep questionnaires (PSQ) were applied. Per results of the PSQ, patients with a mean of >= 0.33 were defined as the high-risk group. Results A total of 25.8% children were in the high-risk group, with the most convex profile, high-angle growth direction, and mandibular retrognathy. The prevalence of habitual snoring, mouth breathing, and dry mouth was 48.4%, 64.5%, and 87.2% among all high-risk children, respectively. Conclusion Convex profile, high-angle growth direction, and retrognathic mandible were determined as risk factors for SDB. The prevalence of dry mouth, mouth breathing, and snoring was higher in the high-risk group.Öğe Evaluation of the relationship between severe early childhood caries and vitamin D(Elsevier, 2022) Duman, Sacide; Selen, Merve Bilmez; Demir, PinarObjective: To evaluate the relationship between the factors affecting the formation of severe early childhood caries (S-ECC) in preschool children, dental caries and serum 25-hydroxyvitamin D (25(OH)D) and to contribute to the literature on this subject. Methods: ASA I-II children aged <72 months and their volunteer parents who had no apparent learning disability were included in the study. 25(OH)D, calcium and albumin levels were measured from the serum samples taken from the children. Dft, dfs and plaque scores were calculated after the oral examination of the children. Parents were asked to fill out a questionnaire assessing the child's dietary habits and family demographics. Results: Total of 175 children (56% male) participating in the study (n = 98; ECC, n = 77; caries-free). S-ECC was present in 42.8% of children with adequate 25(OH)D levels and 63.4% of children with deficient or insufficient levels. Children with S-ECC had significantly lower mean 25(OH)D levels than those caries-free. A very weak negative correlation was detected between 25(OH)D level and dft score. Conclusions: It was difficult to confirm the relationship between 25(OH)D levels and S-ECC. Again, there was a weak correlation between the dft score and 25(OH)D levels.

Methods: One hundred fifty dental radiographs of children with and without ST at the ages of 6.0 to 14.9 years were included in this study. The children in both groups were age and sex-matched. The lower left-side 7 permanent teeth were evaluated according to the Demirjian method, DA was determined. The difference between chronological age (CA) and DA (CA-DA) for the children with and without ST and further based on the number and localization of ST were calculated. Results: For all groups, the mean DA values were higher than the mean CA values. The difference between the CA and DA values in the children with ST was higher than the difference in the children without ST. Supernumerary teeth in posterior localization, multiple ST and among boys were observed to increase the differences between the mean CA and DA values. The mean age difference between radiographies in the children with and without ST was similar. Conclusion: Panoramic radiography was found adequate in determination of dental development with the Demirjian method. Dental development was even more advanced in the children with ST in comparison to the control group. Clinicians should keep in mind that the dental developments of children with supernumerary teeth may be advanced.Öğe YOLO-V5 based deep learning approach for tooth detection and segmentation on pediatric panoramic radiographs in mixed dentition(Bmc, 2024) Beser, Busra; Reis, Tugba; Berber, Merve Nur; Topaloglu, Edanur; Gungor, Esra; Kilic, Munevver Coruh; Duman, SacideObjectivesIn the interpretation of panoramic radiographs (PRs), the identification and numbering of teeth is an important part of the correct diagnosis. This study evaluates the effectiveness of YOLO-v5 in the automatic detection, segmentation, and numbering of deciduous and permanent teeth in mixed dentition pediatric patients based on PRs.MethodsA total of 3854 mixed pediatric patients PRs were labelled for deciduous and permanent teeth using the CranioCatch labeling program. The dataset was divided into three subsets: training (n = 3093, 80% of the total), validation (n = 387, 10% of the total) and test (n = 385, 10% of the total).
