Tooth discoloration might constitute a major problem for patients undergoing endodontic procedures, including obturation. Iatrogenic teeth discoloration might be a burden because it is time-consuming and hard to blench even if it were effective in removing the tooth stains in compared with traumatic tooth discoloration which is easy to deal with. Accordingly, clinicians must have a comprehensive understanding of the potential discoloration effects of the current sealers that are indicated for administration in many of the obturation procedures to enhance the prognosis and the relevant outcomes. In the present study, the aim to conduct a literature review about the potential iatrogenic discoloration effects of some endodontic sealers when conducting obturation procedures, based on the current evidence from the relevant studies. Among the reported agents to induce discoloration, calcium hydroxide, zinc oxide eugenol (ZOE), resin, glass ionomer, and silicon-based sealers have been reported to cause significant degrees of discoloration. Moreover, among the included studies AH-26 seems to be the least significant modality to include discoloration;however, discoloration could still be detected. With the recent technological advances, bioceramic sealers should be able to overcome this problem, especially for areas with the highest esthetic concerns. Accordingly, further investigations might be needed to enhance the quality of the current modalities and to obtain better outcomes.

The accuracy of the intraoral digital impression systems has been previously reported to refer to the quality of the obtained data from the related scanning procedures, irrespective of the quality of the clinical outcomes and the estimated costs. Trueness and precision have been frequently found among studies in the literature as two terms describing the accuracy of the intraoral digital impression systems. Various digital impression modalities have been proposed among studies in the literature and were investigated for estimation of their accuracy. The paper aims to review and discuss the most common literature regarding the current common systems and their accuracy among the different studies in the literature. According to the results, Chairside Economical Restoration of Esthetic Ceramic (CEREC) systems appear to have the highest estimated rates of trueness and precision as compared to the other modalities while the iTero system appears to have the lowest estimated rates. However, some studies have reported contradicting results and the current evidence is mainly based on findings from in vitro investigations. Accordingly, further studies might be needed for further validation of the current evidence and strengthening the quality of the future potential implications for clinicians.

Aim. To evaluate the antibacterial activity of four endodontic sealers on Enterococcus faecalis by a direct contact test. Material and Methods. Enterococcus faecalis was used as a test organism. Direct contact test which is based on measuring the effect of close contact between test bacteria and tested material on the kinetics of bacterial growth was performed to overcome the disadvantages of agar diffusion test. The sealers tested were zinc oxide eugenol-based sealer, glass-ionomer-based sealer, polydimethyl-siloxane-based sealer, and urethane dimethacrylate resin-based sealer. Data was collected by recording the optical density with the help of a spectrophotometer. Results. The sealers exhibited different inhibitory effects. The results obtained were subjected to statistical analysis by Kruskal Wallis analysis of variance and Dunn's multiple comparison test. Group comparison showed very highly significant difference between the groups. Conclusion. Zinc oxide eugenol-based sealer was the most effective and urethane dimethacrylate resin-based sealer was the least effective against Enterococcus faecalis, whereas glass-ionomer-based and polydimethyl-siloxane-based sealers were effective only for a short period. Inhibition of the bacterial growth is related to the direct contact of the microorganism with the sealer.

Background: Bipolar affective disorder (BPAD) is one of the most common severe mental illnesses that cause morbidity. Stigma can negatively influence the disease experience in patients with BPAD. Significant differences are observed in the attributes of stigma across the various sociocultural milieus. The current review was thus conducted to compile the evidence regarding the burden and correlates of various forms of stigma in BPAD in India. Methods: An exhaustive literature review was conducted in PubMed, MedIND, and Google Scholar to identify Indian studies conducted on stigma in BPAD. The broad themes in various forms of stigma were identified (qualitative analysis). Quantitative analysis of measures of stigma was done, calculating the effect size in BPAD and comparator groups (schizophrenia and anxiety disorders) using standardized mean difference. Results: Overall, 12 studies could be identified for qualitative analysis, and 5 were used for quantitative analysis. Overall, the current evidence points out that the stigma in BPAD is less than that in schizophrenia but more than that in anxiety disorders. Internalized stigma in BPAD is correlated with poor self-esteem, reduced community participation, and low quality of life. Caregivers of patients with BPAD also experience significant stigma. Conclusions: The review shows that stigma in BPAD is substantial. It also draws attention to the fact that the research regarding stigma in BPAD is lagging behind. This review also provides a platform to develop an intervention in the Indian scenario, where further research should be carried out.

Computerized auditory training (CAT) is a convenient, low-cost approach to improving communication of individuals with hearing loss or other communicative disorders. A number of CAT programs are being marketed to patients and audiologists. The present literature review is an examination of evidence for the effectiveness of CAT in improving speech perception in adults with hearing impairments. Six current CAT programs, used in 9 published studies, were reviewed. In all 9 studies, some benefit of CAT for speech perception was demonstrated. Although these results are encouraging, the overall quality of available evidence remains low, and many programs currently on the market have not yet been evaluated. Thus, caution is needed when selecting CAT programs for specific patients. It is hoped that future researchers will (a) examine a greater number of CAT programs using more rigorous experimental designs, (b) determine which program features and training regimens are most effective, and (c) indicate which patients may benefit from CAT the most.

Although North Korea is one of the most closed countries in the world, it has long been pursuing international cooperation with other countries in order to upgrade the quality of its film industry to international standards. Preceding studies on this topic have mainly focused on the political influences behind filmmaking in general and very few studies have exclusively dealt with North Korea’s international co-productions. In this respect, in order to develop a comprehensive understanding of the internalization strategy of North Korea’s film productions, this paper uses the global value chain as a framework for analysis. This approach helps understand the internationalization pattern of each value chain activity of film co-productions in terms of the film location and the methods for collaborating with foreign partners. By dividing the evolution of North Korea’s international co-productions into three periods since the 1980s, this paper finds that although North Korea has shown mixed results with different aspects of the film value chain, it has generally improved its internationalization over the three periods. This paper further provides strategic directions for North Korea by learning some of the successful Chinese experiences in the film sector regarding collaboration with foreign partners—to foster a win-win situation for all involved parties.
