Children with mentally ill parents are at risk of developing mental health problems themselves. To enhance early support for these children may prevent mental health problems from being transmitted from one generation to the next. The sample (N = 219) included health professionals in a large university hospital, who responded to a web-based survey on the routines of the mental health services, attitudes within the workforce capacity, worker’s knowledge on the impact of parental mental illness on children, knowledge on legislation concerning children of patients, experience, expectations for possible outcomes of change in current clinical practice and demographic variables. A total of 56 % reported that they did not identify whether or not patients had children. There were no significant differences between the groups (identifiers and non-identifiers) except for the two scales measuring aspects of knowledge, i.e., Knowledge Children and Knowledge Legislation where workers who identified children had higher scores. The results also showed that younger workers with a medium level of education scored higher on Positive Attitudes. Furthermore, workers who reported to have more knowledge about children and the impact of mental illness on the parenting role were less concerned about a child-focussed approach interfering with the patient-therapist relation.

<![CDATA[Copper Ion as a New Leakage Tracer]]>

Statement of Problem: Most failures of root canal treatments are caused by bacteria. Studies showed that the most common cause of endodontic failures were the incomplete obturation of the root canal and the lack of adequate apical seal. Some in-vitro methods are used to estimate sealing quality, generally by measuring microleakage that allows the tracer agent to penetrate the filled canal.

Purpose: Conventional methods of evaluating the seal of endodontically treated teeth are complicated and have some drawbacks. We used copper ion diffusion method to assess the leakage and the results were compared to dye penetration method.

Materials and Method: The crowns of 21 extracted teeth were cut off at the CEJ level. After preparing the canals, the teeth were placed in tubes containing saline. They were divided randomly into 15 experimental cases; 3 positive and 3 negative controls. Positive controls were filled by single cone without sealer while the experimental and the negative control groups were filled by lateral technique. The coronal portion of gutta was removed and 9mm was left. The external surface of each tooth was coated with nail polish. Two millimeters of apical portion was immersed into 9ml of distilled water and 0.3ml of CuSO4 solution was injected into the coronal portion. After 2 days, copper sulfate was measured by an atomic absorption spectrophotometer. The teeth were then immersed in 2% methylene blue for 24 hours, sectioned and the extent of dye penetration was measured by a stereomicroscope.

Results: The maximum and minimum recorded copper ion concentrations for the experimental group were 18.37 and 2.87ppm respectively. The maximum and minimum recorded dye penetrations for the experimental group were 8.5 and 3.5mm respectively. The statistical analysis, adopting paired samples test, showed poor correlation between average recorded results of two methods.

Conclusion: Based on our results, there was no significant correlation between the dye penetration and the copper ion diffusion methods.
