Aim: The aim of this study was to measure the knowledge levels and attitudes of medical students in Kahramanmaraş city on traumatic dental injuries, particularly dental avulsion. Methodology: A total of 224 students studying at the medical school in Kahramanmaraş province were included in this research. The students filled out two-part questionnaire forms containing 17 items in total. We used descriptive frequency analysis, crosstabs, and the chi-square test. Results: Only 7.6% of the students had received relevant training on dental injuries; however, 70.6% did not find the training sufficient. In the case report on replanting a primary tooth, 70.1% of the participants agreed that the primary tooth should not be replanted. In the case report on replanting a permanent tooth, 70.5% of them stated that, although they knew the fallen tooth to be a permanent tooth, they would refer the patient to a dentist immediately because they did not have relevant knowledge for the case. Additionally, 7.6% of the participants stated that if a permanent tooth was avulsed, they would keep the tooth in milk. Conclusion: We concluded that students majoring in medicine had insufficient knowledge levels and attitudes regarding dental injuries leading to avulsion, and we believe this subject needs to be covered by the relevant curriculum.   How to cite this article: İpek S, Soğukpınar Önsüren A.

Objective This study aimed to assess the role of thiol/disulfide homeostasis and oxidative stress in the saliva of children with severe early childhood caries (S-ECC). Methods Eighty children aged 3 to 6 years were involved in this case-control study. The study consisted of two groups: the study group (S-ECC) and the control group with no caries. Thiol/disulfide homeostasis and antioxidant levels were calculated after obtaining unstimulated saliva samples from all participating children. Results The native/total thiol and total oxidant status (TOS) levels of the study group were higher than those of the control group, though not statistically significant (p > 0.05). The oxidative stress index (OSI) value was significantly higher in the study group compared to the control group (p = 0.024). Conclusion Our results confirmed that the thiol/disulfide homeostasis was reduced, and disulfide formation, which is rereducible to thiol, was insufficient in children with S-ECC to compensate oxidative stress compared with the control group. Also, thiol levels were inadequate to compensate for oxidative stress, and thiol/disulfide homeostasis was not an independent parameter for S-ECC. Besides, the increases in the TOS level and OSI value show that oxidative stress had significant effects on S-ECC's etiopathogenesis.

Objective: In the literature, it is still unclear whether the trabecular structure of the jaw in subjects with hypodontia is different from those without hypodontia. Hence, the aim was to determine whether the mandibular trabecular bone structure of children and adolescents with hypodontia differs from the control group by using the fractal analysis method in this study.Materials and Methods: A total of 138 radiographs of 69 cases and 69 control subjects (mean age 13.2±10.1) were evaluated. The age and gender of subjects in the case and control groups were matched. Three regions of interest (ROI) were selected from the panoramic radiographs. Mann-Whitney U and Wilcoxon tests were used. p<0.05 was accepted for the significance value.Results: The mean fractal dimension (FD) values of ROI1, ROI2, and ROI3 were 1,25, 1,20, and 1,13, respectively. The means FD values obtained from the ramus region were higher than the other regions (p<0.05). The FD values did not differ significantly according to gender and age (p>0.05). The FD values of the case group were lower than the control group for ROI3 (p<0.05).Conclusions: The results of this study showed that the mandibular trabecular bone quality of pediatric patients with one missing tooth was different from the healthy group. The difference in the mean FD values from the ROIs indicates that the ramus has a denser structure than the mandibular corpus. Therefore, it shows that individuals with hypodontia may need additional procedures in cases that require orthodontic and implant treatment.Clinical Relevance: Clinicians should consider that individuals with hypodontia may need additional procedures in cases requiring orthodontic and implant treatment.
