Introduction: Long-term clinical evaluation of dental implants and their surrounding structures is of utmost importance to acquire knowledge about reasons for implant success and failure.However, accurate and reproducible results are difficult to obtain. The aim of the present study was to examine bone height around endosseous implants on digital conventional radiographs (DCR) and direct digital subtraction images (DSI) prior to loading.Materials and methods: In this experimental study, bone height around 10 implants in 6 patients was assessed by 2 observers. Standardized digital radiographs were obtained just a week and 3 months postoperatively and subtracted by means of EMAGO software. Then the observers evaluated bone height on DCRs and DSIs. MINITAB software and paired t-test were used for statistical analysis (a=0.05).Results: Comparative evaluation of bone height indicated significantly higher values on DCR than on DSI (p value=0.002). The observers also had statistically significant variability in this assessment (p value=0.00003).Conclusion: DSI demonstrated lower values of linear measurement of bone height around endosseous implants compared with DCR. Interobserver variability should be considered when comparing values from follow-up studies.

The criterion for determining the sample size was also determined to reach the saturation volume. According to the number of specialists who were identified and the conditions expected by the researcher for the interview, with the number of 10 specialists familiar with personal branding (including specialists in the field of business management who have directly studied and implemented marketing and branding in their field and specialists in the field of information science and science who are familiar with scientific branding and visibility) and professors and experts familiar with education and industry were interviewed. The interview questions were designed to determine the framework of the learning package and based on the dimensions and components of the personal brand digital storytelling learning model for students. After the information reached the saturation volume, the obtained data were thematically analyzed, and with the help of the results of thematic analysis, firstly, the framework and then the learning package based on the personal brand digital storytelling learning model were designed for students.Phase 2: Content Validation Using CVR and CVIThe second phase aimed to validate the content validity of the developed learning package. Content Validity Ratio (CVR) and Content Validity Index (CVI) served as the primary tools for this assessment. A panel of 10 experts and professors purposefully selected for their expertise in branding and the education industry participated in the evaluation process. Their feedback on the learning package content played a crucial role in refining both the framework and the overall learning materials to ensure optimal alignment with learning objectives. Following these revisions, the package underwent a final evaluation by an additional 5 experts using CVR and CVI. By incorporating their insights and addressing any remaining issues, the researchers were able to finalize the learning package, guaranteeing its content validity and effectiveness for its target student audience.Discussion and conclusion :This study designed a digital storytelling learning package for students to build their personal brands. The program consists of a framework with four dimensions and 15 components delivered in eight sessions. Each session focuses on a specific aspect of personal branding and digital storytelling.The program was validated by experts to ensure it equips students with the necessary skills. The validation process involved measuring the content validity using CVR and CVI. The positive results confirmed the program's effectiveness in achieving its learning objectives.The study acknowledges limitations such as the lack of specific theoretical frameworks and the difficulty finding experts in all three relevant domains. To improve future research, the study suggests incorporating international experts and investigating the impact of personal branding on students' entrepreneurial inclinations. Additionally, implementing the program in classrooms can provide further validation of its real-world effectiveness.In conclusion, by addressing the limitations and pursuing the proposed future directions, researchers have the opportunity to significantly advance the field of digital storytelling for student personal branding. A robust theoretical foundation, international collaboration, a focus on entrepreneurial impact, and real-world classroom validation can pave the way for a more comprehensive and impactful learning experience. Ultimately, this will empower students to develop strong personal brands, allowing them to stand out in a competitive job market and navigate their professional journeys with confidence.

Introduction: From a long time ago, benefiting from technology has been an inevitable thing for human interests, which is born and based on science. It can be claimed that there is harmony between ethics, science and technology, which promote each other. In this article, the researcher discusses this harmony and compatibility. Material and Methods: The current review study was descriptive and using the study of sources and research keywords among the books and articles published in the databases of Thomson Information Institute, Science Direct and Pub Med. Conclusion: As science and technology continue to advance and become more integrated into our daily lives, ethical considerations become increasingly important. For example, the rise of artificial intelligence (AI) has raised questions about the potential implications of creating machines that can make autonomous decisions and take actions. If science and technology were considered as a tool, it should have been able to subjugate humans and influence all aspects of behavior and values. While it has become a problem that eventually becomes aligned with morality by applying reason, and people now seek help from it as a tool.

Due to high speed computer networks, the use of digitally formatted data has increased many folds. The digital data can be duplicated and edited with great ease which has led to a need for effective copyright protection tools. Digital Watermarking is a technology of embedding watermark with intellectual property rights into images, videos, audios and other multimedia data by a certain algorithm. Digital watermarking is a well-known technique used for copy rights protection of multimedia data. A number of watermarking techniques have been proposed in literature. Digital Watermarking is the process that embeds data called a watermark into a multimedia object such that watermark can be detected or extracted later to make an assertion about the object. A variety of techniques in different domains have been suggested by different authors to achieve above mentioned conflicting requirements. All the watermarking techniques are different from each other and are used for differing applications.

This comprehensive review study examines photogrammetry as a digital imaging technique in modern dentistry. Photogrammetry, using multiple images from various angles, can accurately determine the position of objects in space and create highly accurate three-dimensional models. This technique, initially developed for industrial and mapping applications, is now increasingly used in digital dentistry. This article reviews the photogrammetry method, the types of devices used (intraoral and extraoral), and its clinical applications in various dental fields, including implantology, orthodontics, and maxillofacial surgery. It also addresses the advantages and limitations of this technique, including accuracy, speed, cost, and ease of use. The results of this review show that photogrammetry, as an accurate and efficient imaging method, can help improve the quality of digital dental treatments. The high accuracy of photogrammetry enables precise recording of the position of implants, teeth, and facial structures and can contribute to the predictability and accuracy of treatments. The introduction of portable intraoral and extraoral photogrammetry devices has made access to this technology easier in dental offices and has made it possible to benefit from its advantages in everyday clinical conditions. Overall, photogrammetry is emerging as a powerful tool in digital dentistry and can help improve the accuracy, efficiency, and predictability of dental treatments. However, further research is needed to more accurately investigate the factors affecting the accuracy of photogrammetry and evaluate its clinical applications in real-world conditions.
