Introduction: Child abuse and neglect (CAN) are social and public health problems. Access to oral health care for abused and neglected children is a challenge. The aim of this study was to assess the attitudes and knowledge of dental students from Bosnia and Herzegovina towards CAN. Materials and Methods: A cross‐sectional survey was conducted among 263 dental students from two public universities in Bosnia and Herzegovina. The students answered 31 questions about the topic of CAN. The study population was categorised by year of study into six groups. Pearson's chi‐squared test was used to analyse differences among participants regarding the year of study. The level of significance was set at p < 0.05. Results: The results show that 10.26% of total participants had experienced some knowledge about the topic of CAN during their studies, 17.87% had read about it in professional dental literature and 8.74% had some form of education and training on the topic. Over 50% of participants answered all of the questions about social indicators of CAN correctly. The knowledge of the study participants was found to be deficient concerning some physical signs of CAN found in the orofacial region. For a significant number of questions 'I don't know' was a frequent answer. Conclusion: The level of knowledge of dental students from Bosnia and Herzegovina regarding the challenge of CAN is insufficient. An important strategy this to improve this is to increase the education and training of child abuse and neglect in dental curriculums. [ABSTRACT FROM AUTHOR]

Objective. The causes of internal posteruptive discoloration of teeth are bleeding, necroses, infections, and endodontic filling materials. The aim of this study was to establish the results of bleaching endodontically treated teeth using walking bleach, in-office, and combined techniques, using 30% carbamide peroxide and 35% hydrogen peroxide, as well as the effect of etiological factors, and the time elapsed after endodontic treatment on the success of bleaching. Materials and Methods. The research involved 30 endodontically treated teeth in healthy patients. Retroalveolar X-rays were taken to check the quality of root canal obturation. Endodontic treatment and obturation were carried out on the discolored non-vital teeth without any previous endodontic treatment. Before bleaching, two millimeters of the filling were removed from the root canal and the very entry into the canal was protected with glass ionomer cement. The teeth were divided into three groups, depending on the bleaching technique: walking bleach technique (10 patients), in-office technique (10 patients), and combined technique (10 patients). The teeth were bleached with 30% carbamide peroxide and 35% hydrogen peroxide. The bleaching procedure was repeated in all the patients three times. The color of all teeth was determined based on the Vita Classic guide before and after bleaching. The Χ2 square and Kruskal–Wallis tests were used to identify differences in teeth bleaching results. Results. A statistically significant difference (p < 0.05) was established between bleaching success and the time elapsed after endodontic treatment. There were no statistically significant differences observed between the bleaching success and etiological factors, bleaching techniques, or bleaching agents. Conclusions. The effectiveness of non-vital tooth bleaching is affected by the time elapsed after endodontic treatment. [ABSTRACT FROM AUTHOR]
