(Korean Acad Oral & Maxillofacial Radiology, 2022) Kaya, Emine; Gunec, Huseyin Gurkan; Aydin, Kader Cesur; Urkmez, Elif Seyda; Duranay, Recep; Ates, Hasan Fehmi
Purpose: The aim of this study was to assess the performance of a deep learning system for permanent tooth germ detection on pediatric panoramic radiographs.Materials and Methods: In total, 4518 anonymized panoramic radiographs of children between 5 and 13 years of age were collected. YOLOv4, a convolutional neural network (CNN)-based object detection model, was used to automatically detect permanent tooth germs. Panoramic images of children processed in LabelImg were trained and tested in the YOLOv4 algorithm. True-positive, false-positive, and false-negative rates were calculated. A confusion matrix was used to evaluate the performance of the model.Results: The YOLOv4 model, which detected permanent tooth germs on pediatric panoramic radiographs, provided an average precision value of 94.16% and an F1 value of 0.90, indicating a high level of significance. The average YOLOv4 inference time was 90 ms. Conclusion: The detection of permanent tooth germs on pediatric panoramic X-rays using a deep learning-based approach may facilitate the early diagnosis of tooth deficiency or supernumerary teeth and help dental practitioners find more accurate treatment options while saving time and effort.

Drug Delivery (Nano)Platforms for Oral and Dental Applications: Tissue Regeneration, Infection Control, and Cancer Management
(Wiley, 2021) Makvandi, Pooyan; Josic, Uros; Delfi, Masoud; Pinelli, Filippo; Jahed, Vahid; Kaya, Emine; Tay, Franklin R.
The oral cavity and oropharynx are complex environments that are susceptible to physical, chemical, and microbiological insults. They are also common sites for pathological and cancerous changes. The effectiveness of conventional locally-administered medications against diseases affecting these oral milieus may be compromised by constant salivary flow. For systemically-administered medications, drug resistance and adverse side-effects are issues that need to be resolved. New strategies for drug delivery have been investigated over the last decade to overcome these obstacles. Synthesis of nanoparticle-containing agents that promote healing represents a quantum leap in ensuring safe, efficient drug delivery to the affected tissues. Micro/nanoencapsulants with unique structures and properties function as more favorable drug-release platforms than conventional treatment approaches. The present review provides an overview of newly-developed nanocarriers and discusses their potential applications and limitations in various fields of dentistry and oral medicine.

Effect of a needle-free system versus traditional anesthesia on pain perception during palatal injections in children
(Wiley, 2023) Kaya, Emine; Yildirim, Sinem
Background Needle-free injection systems can contribute to the prevention of needle-related pain during palatal infiltration anesthesia (PIA) in children. Research on this topic in children is required. Aim The purpose of this clinical study was to evaluate the effectiveness and patient preference of a needle-free system versus traditional anesthesia (TA) on pain perception during PIA in children. Design The study was designed as a randomized, controlled crossover clinical study with 48 children aged 6-12 years requiring dental treatment with PIA in bilateral maxillary primary molars. TA was applied on one side and the Comfort-in (TM) injection system (CIS) on the other side in two separate sessions. Then, patient preference was recorded. The pain perception during PIA was evaluated using the Wong-Baker FACES Pain Rating Scale (PRS) and the Face, Legs, Activity, Cry, Consolability (FLACC) Scale. The data were analyzed for statistical significance (p < .05). Results There were statistically significant differences between the TA and the CIS according to the PRS and FLACC Scale scores. On both scales, significantly higher pain ratings were observed in the TA group during PIA (p < .001). There was a statistically significant difference in terms of patient preference (p < .001). Although 77.1% (n = 37) of the children preferred the CIS, 22.9% (n = 11) preferred the TA. Moreover, patient preference for the CIS was significantly higher in older children (p < .01). Conclusions The application of a needle-free system during PIA ensured a decrease in pain perception in children.

The effects of pediatric dentifrices with different types of fluoride on the color change of restorative materials
(Istanbul Univ Press, Istanbul Univ Rectorate, 2022) Kaya, Emine; Yildirim, Sinem
Purpose This study aimed to evaluate the effects of dentifrices with different fluoride content on color change of restorative materials commonly used in pediatric dentistry. Materials and Methods Three restorative materials (glass hybrid [Equia Forte (EF)], glass carbomer [GCP Glass Fill (GCP)] and compomer [Dyract XP (DXP)]) were used to prepare 120 disc shaped specimens by using a Teflon ring. Four dentifrice groups were created as Sodium Fluoride (NaF), Amine Fluoride (AmF), Stannous Fluoride (SnF2) and no-fluoride (n=40). Simulated tooth brushing was performed for each specimen by applying 6720 strokes for 6 months. Color changes [CIEDE2000 (Delta E00)] were calculated by using generalized linear model procedure and the data were subjected to two-way analysis of variance. Results The highest color changes for NaF and AmF dentifrice groups were observed in the GCP restorative material (p<0.05). The color changes of restorative materials tested with SnF2 dentifrice group were statistically different (p<0.05) in each restorative material and Delta E-00 values were observed as GCP> EF>DXP. SnF2 dentifrice provided better color stability for all restorative materials when compared to NaF and AmF dentifrices; although, this was not statistically significant. GCP underwent significant discoloration values when brushed with all types of dentifrices. Conclusion Although the glass carbomers caused significant color change, the compomers seem to be more resistant to the color change when brushed with all types of dentifrices. The fluoride content of dentifrices is crucial for the color change of restorative materials.

Effects of photobiomodulation with different application parameters on injection pain in children: a randomized clinical trial
(Mre Press, 2023) Elbay, Mesut; Elbay, Ulku Sermet; Kaya, Emine; Kalkan, Ozlem Peyman
Photobiomodulation (PBM) has gained increasing interest due to its effectiveness in pain reduction in various fields of dentistry. However, the number of studies evaluating the effect of PBM on injection pain in children is very limited. The aim of the study was to evaluate the efficacy of PBM with three different application parameters (doses) + topical anesthesia on reducing injection pain and to compare these results with the placebo PBM + topical anesthesia in children during supraperiosteal anesthesia administration. 160 children were randomly divided into 4 groups, 3 experimental and 1 control, with 40 subjects in each. In the experimental groups, before the anesthesia administration, PBM with a power of 0.3 W was applied for 20, 30 and 40 s in groups 1, 2 and 3, respectively. In group 4, a placebo application of laser was performed. The pain felt during the injection was assessed using the Wong-Baker Faces Pain Rating Scale (PRS), and also the Face, Legs, Activity, Cry, Consolability (FLACC) Scale. Statistical analyses were performed to evaluate the data (p < 0.05). The mean FLACC Scale pain scores were 3.02 & PLUSMN; 2.93, 2.92 & PLUSMN; 2.54, 2.12 & PLUSMN; 1.89 and 1.77 & PLUSMN; 1.90 for the placebo group, and Groups 1, 2, and 3, respectively. Furthermore, the mean PRS scores were 1 & PLUSMN; 1.03, 0.95 & PLUSMN; 0.98, 0.80 & PLUSMN; 0.822 and 0.65 & PLUSMN; 0.921 for the placebo group, and Groups 1, 2 and 3, respectively. The "no pain response" rate was higher in Group 3 as compared to Groups 1, 2, and placebo according to the FLACC Scale and PRS; however, no difference was found between the groups (p = 0.109, p = 0.317). Injection pain in children did not differ with placebo and PBM applied with a power of 0.3 W for 20, 30 and 40 s.

MINDFULNESS, PERCEIVED STRESS AND COPING STRATEGIES DURING COVID-19 PANDEMIC IN TURKISH DENTISTRY STUDENTS
(Dokuz Eylul Univ inst Health Sciences, 2022) Yildirim, Sinem; Kaya, Emine
Purpose: The aim of the present study was to evaluate the association between perceived stress, mindfulness and coping strategies of undergraduate dental students during the COVID-19. Material and Methods: A cross-sectional study was conducted among 128 undergraduate dental students in 3rd, 4th and 5th grade. Students completed surveys including the Perceived Stress Scale (PSS), the Mindful Attention and Awareness Scale (MAAS) and the Coping Orientation to Problems Experienced inventory (COPE). Data were analyzed using the Mann-Whitney U-test, Analysis of Variance, Student's t-test, Kruskal Wallis test and Spearman correlation. Results: A negative association was found between the MAAS and PSS according to the Spearman's correlation coefficient (rs =-0.823, p<0.001). There were positive relationships between MAAS and COPE inventory subscales of positive reinterpretation and growth (rs = 0.385, p < 0.001); use of instrumental social support (rs = 0.233, p = 0.008); active coping (rs = 0.384, p < 0.001); use of emotional social support (rs = 0.208, p = 0.018); planning (rs = 0.244, p = 0.005). There were negative relationships between MAAS and COPE inventory subscales of behavioral disengagement (rs =-0.245, p = 0.005); alcohol-drug use (rs =-0.233, p = 0.008). Conclusion: Dental students with a high level of mindfulness had a low level of perceived stress. The findings may guide the mindfulness-based stress reduction programs or stress awareness lectures development and implementation within the academic curriculum.

The Relationship of Dental Anxiety, Behaviour, Temperament and Dental Caries in Children
(Penerbit Univ Sains Malaysia, 2021) Kaya, Emine; Yildirim, Sinem
The first dental examination is a major step that is affected by many factors and determines the dental treatment process. The main objective of this study was to evaluate the association of child temperament with child dental anxiety, parental dental anxiety, dental behaviour and dental caries. The study consisted of 100 children aged 3 to 6 who were attending their first dental examination and their accompanying parents. The Facial Image Scale (FIS), Frankl's Behaviour Scale (FBS), Corah's Dental Anxiety Scale (CDAS) and the Short Temperament Scale for Children (STSC) were used for assessment. The DMFT (decayed, missing and filled teeth) score of each child was recorded. Children who exhibited negative behaviour on the FBS had the highest rhythmicity scores (p = 0.008). The mean DMFT score of children in the rhythmicity temperamental dimension was relatively high (p = 0.008). The parents of children defined as negative on the FBS had high dental anxiety levels on CDAS (p < 0.001). Children whose parents had higher dental anxiety levels showed higher dental anxiety (p = 0.007). The success rate of dental treatment procedures may be increased by improving dentists' knowledge of dental anxiety related to the child's temperament and integrating parental support to reduce dental anxiety.

Süt dişlerinde demir ilacına bağlı renklenmeler üzerine yüzey örtücü kullanımının etkisi
(2021) Kaya, Emine
Amaç: Bu çalışmanın amacı, süt dişlerine uygulanan yüzey örtücü ajanların, çocuklarda kullanılan iki farklı formdaki demir şurubunun meydana getirdiği renklenme üzerindeki etkisinin incelenmesidir. Gereç ve Yöntem: Çalışmada toplam 66 adet çürüksüz süt dişi, her bir grupta 11 adet örnek bulunacak şekilde rastgele 6 gruba ayrıldı. Fe+2 (ferröz sülfat) içeren Ferrum Haussman (Vifor International Inc., İsviçre) ve Fe+3 (ferrik polimaltoz) içeren FerroSanol B (UCB Pharma GmbH, Almanya) demir şurubu kullanıldı. Kontrol grubu olarak distile su tercih edildi. Her bir şurup ve kontrol grubundaki örneklerin yarısına yüzey örtücü ajan olarak BisCover LV (Bisco Inc., Itasca, IL, ABD) uygulandı ve diğer yarısına herhangi bir işlem yapılmadı. Her bir diş örneği günde 3 kere 8 saat aralıklarla 2’şer dakika bulunduğu gruba göre demir şuruplarına veya distile suya batırıldı. Toplamda 252 daldırma döngüsü uygulandı. Renk değişimleri spektrofotometre (Vita EasyShade Advance 4.0, Ivoclar Vivadent, Liechtenstein) kullanılarak ölçüldü. İki yönlü varyans analizi, renk değişiminin değerlendirilesinde kullanıldı. Bulgular: Fe+2 içeren demir şurup grubundaki dişler Fe+3 içeren demir şurubu grubundaki dişlerden daha fazla renk değişimi gösterdi. (p<0,001) Tüm gruplarda yüzey örtücü uygulanan dişlerde uygulanmayan dişlere göre daha fazla renk değişimi görüldü. (p<0,001) Sonuçlar: Bu invitro çalışmada Fe+2 içeren demir şuruplarının Fe+3 içeren şuruplara göre daha fazla renklenmeye neden olduğu görüldü. Yüzey örtücü ajanlar süt dişlerinde demir ilacına bağlı oluşan renklenmeleri önlemekte etkili değildir.
