3.Generalized Pulp Stones of Primary Dentition in a Patient with Molar-Incisor Malformation : A Case Report
Journal of Korean Academy of Pediatric Dentistry 2020;47(3):337-343
Molar-incisor malformation (MIM) is a new type of root anomaly reported recently. The characteristics of MIM are dysplastic root formations, constriction of pulp chambers and presence of calcified matrices at the level of cementoenamel junction in permanent first molars and primary second molars. In some cases, permanent maxillary incisors are also affected. The permanent first molars of the patient in this case report were affected with MIM. Generalized pulp stones were observed in overall primary dentition. Micro-computed tomography (micro-CT) imaging and scanning electron microscope-energy dispersive X-ray spectrometer analysis were performed on the extracted mandibular first molar and maxillary primary second molar of the patient. Micro-CT images revealed the discontinuity of enamel directly connected to an accessory canal of the root.

The aim of the study is to compare the fluoride release and recharge properties of glass ionomer cements and ‘alkasite’.
Specimens of two glass ionomer cements (Fuji Ⅸ GP and Riva Self Cure), ‘alkasite’ restorative material (Cention N) and composite resin (FiltekTM Z350XT) were prepared. The fluoride release of each specimen was measured for 28 days. Thereafter, 1.23% acidulated phosphate fluoride (APF) gel was applied to experimental groups. No treatment was performed on control groups. The fluoride release was measured for additional 7 days to evaluate the fluoride recharge properties of each materials.
The fluoride release was highest in Riva Self Cure, followed by Fuji Ⅸ GP, Cention N (p < 0.05). Fluoride release of Cention N was measured to be approximately 49% of Fuji Ⅸ GP’s. After the application of 1.23% APF gel, increases in fluoride release were observed in Riva Self Cure, Fuji Ⅸ GP and Cention N (p < 0.05). Fluoride recharge was observed in Cention N as well as in glass ionomer cements. Further studies are required to evaluate the anti-cariogenic properties of Cention N at clinical conditions.

OBJECTIVES: Shift work is a stressful situation. It is important to know the factors associated with the ability to adapt to a shift work schedule. The aim of the present study was to investigate the association between sleep, as well as personality variables, and the resilience of shift work nurses. METHOD: Self-report questionnaires were administered to 95 nurses who worked in one national university hospital. Connor-Davidson resilience scale, hospital anxiety and depression scale, morningness-eveningness scale, Pittsburgh sleep quality index, other sleep-related questionnaires, and Korean defense style questionnaires were used. RESULTS: Age, shift work duration, off-day oversleep, depression, anxiety, adaptive defense style, and self-suppressive defense style were significantly associated with resilience (p < 0.05). Multiple regression analysis showed that age (beta = 0.34, p < 0.05), depression (beta = -0.25, p < 0.05), adaptive defense style (beta = 0.45, p < 0.001), and self-suppressive defense style (beta = -0.19, p < 0.05) significantly predicted the resilience of shift work nurses. Concerning individual defense mechanisms, resignation (beta = -0.20, p < 0.05), sublimation (beta = 0.19, p < 0.05), omnipotence (beta = 0.19, p < 0.05), and humor (beta = 0.20, p < 0.05) significantly predicted the resiliency. CONCLUSION: The findings indicate that a specific defense style and other mechanisms were associated with the resilience of shift work nurses. A future prospective study with more participants could further clarify the relationship between sleep-related variables, as well as personality factors, and resilience of shift work nurses.

The purpose of this study was to evaluate the mediating effect of depressive symptoms on the relationship between adverse childhood experiences (ACEs) and problematic internet use. The study participants were 180 students between the ages of 9 and 18 years. Path analysis was performed to measure the relationships among ACEs, depressive symptoms and problematic internet use. ACEs significantly affected depressive symptoms (standardized regression weight, 0.36; P < 0.01), and depressive symptoms also affected problematic internet use (standardized regression weight, 0.40; P < 0.01). We found that depressive symptoms had a significant mediating effect on the relationship between problematic internet use and ACEs. The management of depressive symptoms would be important to prevent problematic internet use in children and adolescents with ACEs.
7.Sleep and Resilience.

Good sleepers tend to more resilient than poor sleepers. As sleep and resilience may have a bidirectional relationship, it is important to explore the relationship between healthy sleep and resilience. Objectively and subjectively measured sleep quality showed positive association with resiliency. In one study, more resilient adolescents had higher sleep efficiency, less light sleep, more slow-wave sleep, and a smaller number of awakenings after sleep onset. Circadian typology, jetlag and circadian misalignment may be associated with the capacity to deal with adversity. Eveningness, exposure to chronic jetlag and circadian misalignment might be risk factors for development of psychological problems and mental disorders. Additional studies are needed to evaluate whether promoting healthy sleep behaviors results in increased resilience.

Objective:
This study investigated the types of daily life stressors associated with social media use in adolescents with problematic Internet/smartphone use in a city in Korea.
Methods:
Data from 2,997 Internet and smartphone users who participated in a survey about the actual use of smart digital media in Korea were included. The measurement tools included questionnaires on Internet and smartphone usage patterns and types of daily life stressors as well as the Internet Gaming Use-Elicited Symptom Screen and a smartphone addiction scale. The subjects were divided into a problematic Internet/smartphone use group and a control group. We compared the types of daily life stressors associated with social media use for each group.
Results:
All types of daily life stressors were more prevalent in the problematic Internet use group than in the control group. In the problematic Internet/smartphone use group, the types of daily life stressors that were positively associated with social media use were sibling rivalry and physical health. In the control group, social media use was negatively associated with daily life stressors related to appearance and heterosexual relationships.
Conclusion
There is a need to provide personalized stress management related to social media use for adolescents with problematic Internet/smartphone use.

Methods:
Using a common data model of electronic medical records at a university medical center in South Korea, the study populations were extracted if the depressive patients were treated either with antidepressants only or along with antipsychotics. The suicidal risks were compared with the Kaplan-Meier plot and log-rank test, and the risk factors were accessed using the Cox proportional hazard model.
Results:
All demographic characteristics were similar in the monotherapy group taking only antidepressants and the combination therapy group taking antipsychotics with antidepressants, except for the smoking characteristic (p=0.023). The combination therapy group showed a lower suicidal risk [hazard ratio=0.58, 95% confidence interval (CI)=0.282–1.190] compared to the monotherapy group, which was not significant (p=0.138).
Conclusion
The combination therapy had no beneficial effects on reducing the suicidal risk in patients with depressive symptoms. This study is meaningful in that it is the first attempt to explore a psychiatric behavior/symptom using real-world data based on a common data model of general electronic medical records as well as narrative textual data.
