Assessing injuries in forensic medicine casework, examiners are often confronted with the question of self-infliction versus third parties' influence, respectively, deliberate self-harm versus maltreatment. We report the case of a 40-year-old male who presented with numerous partially healed thermal injuries of different age. These burns were shaped like capital letters and little circles, which were arranged in lines in a regular form. The lesions were found on the whole body with exclusion of face, genitals, hands and feet. Furthermore, four bitemarks at the right shoulder were noted. Investigations revealed that the man had been abused by his 25-year-old wife (presumably a borderline personality disorder patient) for at least 1 year. In addition to another series of abuses, the woman may have inflicted the shaped burns with a hot glue gun as punishment for breaking certain "rules" she had established. When assessing injuries of patients in forensic medicine, several considerations regarding etiology have to be taken into account. In principle, the victim's testimony, the anamnesis, the police investigation results and the findings from the forensic physical examination have to be balanced against each other. The injury pattern in the present case showed contradictory single characteristics both of deliberate self-harm and of maltreatment. After forensic analysis, it was assessed as injuries inflicted by an assistant with the patient's consent.
The study evaluated the influence of different luting materials on the microtensile bond strength of glass fiber posts to root canal dentin. Thirty extracted maxillary premolars were endodontically treated, and the roots were prepared for post cementation using the FRC Postec system (Vivadent). Two luting materials (Multilink, Vivadent and Clearfil Photo Core, Kuraray) were used in combination with three adhesive: Multilink Primer (Vivadent), Clearfil Photo Bond, and Clearfil New Bond (Kuraray). A composite build-up was performed around the root to provide adequate gripping during testing. Specimens were cut to obtain beams with the post in the center and with the radicular dentin overlaid by the composite build-up on each side. Microtensile testing was performed with a universal testing machine at a cross-head speed of 0.5 mm/min. The failure mode was classified under a stereomicroscope and four representative beams of each group were selected for SEM analysis. Bond strength data that were analyzed with two-way ANOVA and Student-Newman-Keuls multiple comparisons tests revealed that adhesive systems, luting materials, and the interaction between these two factors significantly influenced the bond strength results (p < 0.01). Multilink applied with its own adhesive system obtained the best results, while the lowest bond strength was achieved with clearfil photo core in combination with multilink primer.
