Tooth discoloration is a common esthetic concern that may influence psychosocial development and peer interactions during childhood. This in vitro study aimed to compare the discoloration potential of fruit juices frequently consumed by children-black mulberry, organic pomegranate, and organic orange-and to evaluate whether brushing with fluoridated or non-fluoridated toothpastes reduces these changes in primary teeth. Eighty sound primary teeth extracted due to trauma, orthodontic indications, or natural exfoliation and free of caries, restorations, enamel defects, or pre-existing discoloration were included. Samples were divided into four immersion groups (n = 20): saline (control), black mulberry juice, organic pomegranate juice, and organic orange juice. Each group was further divided into brushed and unbrushed subgroups, with brushed specimens treated using either fluoridated or non-fluoridated toothpaste (n = 10). All teeth were immersed for 28 days, and color measurements were obtained at baseline, day 7, and day 28 using a dental spectrophotometer according to the CIELab system. All fruit juices produced clinically perceptible discoloration (ΔE > 3.3), and each juice caused higher staining than the saline control. Black mulberry and pomegranate produced the greatest total discoloration, while orange juice resulted in markedly lower ΔE values. Brushing consistently reduced discoloration across all groups; however, no significant difference was found between fluoridated and non-fluoridated toothpastes, indicating that the mechanical action of brushing-rather than fluoride content-was primarily responsible for stain reduction. These findings reinforce the susceptibility of primary enamel to pigment-rich beverages and highlight the importance of effective brushing habits in minimizing extrinsic discoloration in children. Clinically, these findings suggest that despite the high staining potential of these fruit juices, strict adherence to daily brushing routines can effectively mitigate esthetic degradation in primary teeth, regardless of the toothpaste's fluoride content.

Objectives: This study aimed to compare the content, educational quality, and dependability of videos on Instagram, TikTok, and YouTube about pulp therapy (PT) in pediatric dentistry and endodontics.Methods: Three popular video sites, Instagram (Meta Platforms, Inc.,), TikTok (ByteDance Ltd.), and YouTube (Google LLC), were searched for PT content to analyze for compliance with the American Association of Endodontists and American Academy of Pediatric Dentistry guidelines for clinical endodontists and pediatric dentists. The searched hashtags were #pulpaltherapy, #pulpaltreatment, #pulptherapy, and #pulptreatment. The classification of 158 English-language videos was based on several variables: communication quality, duration, likes and dislikes, views, source, treatment, and genre. The videos were evaluated using a usefulness score and the Global Quality Scale (GQS), Video Information and Quality Index (VIQI), Journal of the American Medical Association (JAMA) score, and modified DISCERN score to rate their quality and reliability. The majority of the videos were published by healthcare professionals, dental clinics, and universities.Results: Significant relationships existed between video length, source of upload, usefulness score, tooth type, pulp status, and VIQI, JAMA, GQS, and DISCERN scores for all three platforms (p<0 .05). A statistically significant relationship existed of YouTube, TikTok, and Instagram with the number of views, number of months since upload, view rates, comments and likes (p< 0.05).Conclusions: TikTok and Instagram reel videos provided high- to moderate-quality information about PT, especially in children, but YouTube may provide more reliable information than other social media tools.

The aim of this study was to evaluate the impact of various polishing methods on the color stability of compomer and composite resin restorations used in anterior restorations within pediatric dentistry. One hundred and twenty disc-shaped specimens (8 mm diameter x 4 mm thickness) were prepared from A2 shade compomer and nanohybrid composite resin to assess color stability in four different polishing systems. Sixty specimens from each material were randomly distributed into five groups (n = 12) according to the polishing method used. Group 1: four-step aluminum oxide discs, Group 2: aluminum oxide discs and rubber kit, Group 3: aluminum oxide discs and felt discs, Group 4: aluminum oxide discs and spiral wheels, and Group 5: no polishing. The specimens were immersed in cherry juice solution for 7 days. The color changes (ΔE) for all materials were assessed using a spectrophotometer at baseline and after 7 days of staining. The collected data were analyzed with the Shapiro-Wilk test, along with the Mann-Whitney U test for comparing two independent groups and the Kruskal-Wallis test for comparing three or more independent groups. Post hoc Bonferroni Corrections were applied to identify the groups causing the differences. As a result of the analyses, statistically significant differences were determined between the staining measurements of the compomer and composite materials across the groups (p < 0.05). The highest level of discoloration for the compomer was in the control group. In conclusion, the selected polishing method influences the degree of discoloration in the compomer groups. In the composite group, polishing methods showed variable effects. Differences were found between the compomer and composite groups. Understanding these effects is crucial for maintaining the esthetic longevity of restorations in young patients.

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™ 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.

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. 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). Conclusions: 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.
