The institution of the modern state, based on the liberal doctrine of social contract, has been questioned in the age of globalization by the formation of paradigmatic transformations of political thought from different think tanks. This kind of criticism of liberal discourse encompasses a range of critical thinkers such as Michel Foucault, Jacques Derrida Giorgo Agamben, Jacques Rancière and others. But the critique of the state by contemporary thinkers is not confined to this category of thinkers, but communitarianism, with its thinkers such as Al-Sadir McIntyre, can be regarded as one of these critical schools of thought in the paradigm of contemporary political philosophy with a critical look at the most important liberal propositions of modern times such as individualism, state neutrality, universality of this kind of thinking and an emphasis on concepts such as communitarianism, virtue, state moral interventionism, and contextualization. The focus of this article will be to examine McIntyre's critical attitude towards the issue of "state neutrality." The question is, "What is Al-Sadir McIntyre's view of the institution of government? And what is his position on the neutrality of the state in liberal thought? "It is assumed that “First of all, McIntyre has no endorsing view of modern government and its grand narrative, and is in favor of communism. It also denies the impartiality of the state in liberal thought and advocates the rule-based interventionism of the state to moralize citizens ". Macintyre is a new Aristotelian thinker who emphasizes the restoration of virtue and prosperity in the modern age as it was in the classical Greek era.

In Islamic perspective, the citizenship model has many differences with the pattern of citizenship common in the Western world, despite similarities, and these kinds of differences go back to their different worldviews. In fact, citizenship patterns in Western societies cannot be reconciled with divine teachings; because identity issues in each of the citizenship patterns are different from each other. Accordingly, the study of the characteristics of each of the citizenship patterns is necessary and by examining identity and norms in each pattern, it is clear that normative and intellectual structures are as important as material structures. In addition, the present study, by patterning from “the Citizenship and Politic of New virtue”, divides citizenship patterns into three categories of inclusive political, cultural, and multicultural coherence. Indeed, this article is an attempt to study and study their possibility and their refusal based on the pattern of citizenship of the Qur'an and the expression of Similarities and differences between them and the authors intend to present the Quran's citizenship model as a whole.

Abstract Objective This cross-sectional study aims to investigate the effect of the cause of missing teeth on the survival and subjective success of dental implant treatment (DIT) in young patients with missing teeth due to non-congenital causes (tooth loss) in comparison to patients with missing teeth because of congenital causes (hypodontia and oligodontia). Material and methods All patients were asked 7 questions to extract information about the survival and subjective success of DIT. Implant survival function was designed using the Kaplan-Meier analysis. Differences in implant success outcomes were studied using binary logistic regression analysis. Results One hundred ten patients aged 18 to 40 years old were included, whereof 32 patients with tooth loss, 25 patients with hypodontia and 53 patients with oligodontia. In the tooth loss group, implant survival reached 96.9%; in the hypodontia group 96.0%; and in the oligodontia group 88.7%. Regarding subjective implant success, patient satisfaction was significantly higher (p < 0.040) among patients with congenital missing teeth in comparison to patients with tooth loss. Other implant success components showed no statistically significant difference (p > 0.050) between the groups. Conclusion The cause of missing teeth does not influence implant survival. However, the cause of missing teeth does have a significant impact on patient satisfaction (implant success), ascertaining young patients with congenital missing teeth as more satisfied of DIT than young patients with tooth loss. Clinical relevance Young patients with tooth agenesis and with an increased number of missing teeth are more content about the treatment with dental implants than patients with tooth loss. Furthermore, a consensus regarding the assessment of implant success is an essential concern for clarification.

Implanted medical devices are widely used across various medical specialties for numerous applications, ranging from cardiovascular supports to orthopedic prostheses and cosmetic enhancements. However, recent observations have raised concerns about the potential of these implants to induce malignancies in the tissues surrounding them. There have been several case reports documenting the occurrence of cancers adjacent to these devices, prompting a closer examination of their safety. This review delves into the epidemiology, clinical presentations, pathological findings, and hypothesized mechanisms of carcinogenesis related to implanted devices. It also explores how the surgical domain and the intrinsic properties and biocompatibility of the implants might influence the development of these rare but serious malignancies. Understanding these associations is crucial for assessing the risks associated with the use of medical implants, and for developing strategies to mitigate potential adverse outcomes.

Autogenous particulate bone grafts are being utilized in oral implantology for minor grafting procedures. This study aimed to investigate the influence of the bone-harvesting technique, donor age, and donor site on proliferation and differentiation of human primary osteoblastlike cells in the cell culture. Autogenous bone particles (20 samples) were harvested from the maxilla and mandible during surgery using two different protocols, and two types of particulate bone grafts were collected: bone chips and bone sludge. Bone samples were cultured in growth medium and, after 2 to 3 weeks, the cells that grew from bone grafts were cultured in the normal and osteogenic medium for 0, 4, 7, and 20 days. DNA, alkaline-phosphatase (ALP), calcium-content measurements, and Alizarin red/toluidine blue staining were performed. Data were analyzed by repeated-measures analysis of variance with Bonferroni test. The level of statistical significance was set at 5% (P < .05). Total DNA, ALP, and calcium content were significantly higher for the bone chip samples compared to the bone sludge samples. Total DNA and ALP content were significantly higher for the patients in age group 1 (= 60 years) compared to age group 2 (> 60 years) and was significantly higher for mandibular samples than maxillary samples on day 20. However, the calcium measurement showed no significant difference concerning donor age and donor site. Data analysis revealed that harvesting technique (bone chips vs bone sludge), donor age (= 60 years vs > 60 years), and donor site (maxilla vs mandible) influenced the osteogenic potential of the collected particulate bone graft. The bone chips were superior in terms of osteogenic efficacy and should be considered a suitable option for particulate bone graft collection. [ABSTRACT FROM AUTHOR]

The present study deals with the analysis of modern medicine and its evolutionary aspects in Iran, Qajar Era with emphasis on pictorial manuscripts. Since health and treatment in Qajar Era was completely unorganized and unstable, introduction of modern medicine can be considered as a new chapter in the medicine history of Iran in the Era of Qajar. The data of this study were collected from among first- hand library sources. This research aims to answer this question: what was the position of modern medicine among the politicians and different spheres of society and what are the factors affecting this evolution. In order to answer the said question, it was supposed that a set of factors involved in the evolution and expansion of modern medicine including the influence of the thought of superiority of modern medicine, the superiority of new education in Dar Ul-Funun, the interest of Qajar kings in using foreign physicians, advantages and positive results of services of modern medicine to society such as hospitals, inoculation, quarantine and individual and public health. Alongside these factors, passage of time, demand and interest of Qajar society which composed of different spheres and pictorial medical manuscripts of Qajar era that contained artistic and aesthetic descriptions as well as anatomical and medical descriptions resulted in prosperity and expansion of modern medicine. The finding of the study, while approving the hypothesis, indicated that all of these factors helped replace traditional medicine with modern medicine during modernity in that era. However, traditional medicine continued its life alongside modern medicine. Therefore, through a descriptive analytical method, the researcher endeavored to answer the question: what were the factors affecting modern medicine by expressing the pictorial aspects and relationship between medical sciences and graphics in Qajar Era? And what were the factors affecting the evolution of modern medicine in Qajar society? Did factors such as hospitals, modern clinics, healthcare preservation centers, quarantine, publications and financial power play a role in the process? Hence, the main goal of this study is to evaluate evolutionary aspects of modern medicine in Iran, Qajar era with emphasis on pictorial manuscripts as well as the changes in people’s outlook on preparation of infrastructures and acculturation to accept and develop the factors of this medicine

Purpose: To compare the fit and clinical performance of screw-retained monolithic zirconia implant fixed dental prostheses (FDPs) fabricated based on either intraoral optical scanning (IOS) or conventional impressions. Materials and Methods: Patients with two posterior tissue-level implants (Regular Neck, Straumann) replacing two or three adjacent teeth were recruited. Impressions were taken with both IOS (True Definition Scanner, 3M Espe) and a conventional (polyether) pick-up impression. Double-blind randomization was performed after impression-taking, and patients were to receive an FDP based on either the digital or the conventional impression. The fit was evaluated, and the time required for adjustments was recorded. Additionally, survival and technical complication rates with a follow-up of 1 year were documented. Results: A total of 38 patients requiring 45 FDPs were included: 24 FDPs in the test (IOS) and 21 in the control (conventional) group. The average adjustment time was 6.92 minutes (SD: ± 10.84; range: 0 to 49) for digital vs 12.38 minutes (SD: ± 14.52, range: 0 to 54) for conventional impressions (P = .090). A proper fit (no adjustments) was achieved in 33.3% of the digital and 28.6% of the conventional group. Forty-two FDPs could be placed within the two planned appointments, and 3 FDPs exhibited an unacceptable fit and required an extra appointment. Eight technical complications occurred during the first year of function. The overall restoration survival rate was 100%. Conclusion: The clinical fit of CAD/CAM FDPs based on digital impressions is comparable to conventional impressions. Screw-retained monolithic zirconia FDPs on Ti-base abutments show low major complication and 100% survival rates in the short term. [ABSTRACT FROM AUTHOR]

Purpose: There is a substantial need to perform studies to evaluate crestal bone loss (CBL) and implant success when using a newly introduced low-speed drilling protocol. Therefore, this study aimed to evaluate the mean CBL and implant success rate by placing implants utilizing two drilling protocols, ie, standard and low-speed drilling protocols. Materials and Methods: A randomized controlled clinical trial was carried out in patients who required dental implants to restore their esthetics and function. The patients were recruited from a university hospital (Academic Centre for Dentistry Amsterdam [ACTA], the Netherlands). Based on the inclusion criteria, patients were randomized to two study groups: (1) control group, standard drilling protocol; and (2) test group, low-speed drilling protocol without saline irrigation. The mean CBL and the implant success rate were evaluated after 12 months of implant placement. Results: Twenty-three patients (15 men and 8 women with a mean age of 57.5 ± 10.7 years) contributed to the study. Forty Camlog screw-line implants were placed (20 implants per study group). After 12 months of implant placement, the mean CBL of implants placed with the standard protocol and the low-speed protocol was 0.206 ± 0.251 mm and 0.196 ± 0.178 mm, respectively. No statistically significant difference could be recorded among both groups (P = .885). Concerning implants placed in the maxilla, the standard drilling group and low-speed drilling group showed a mean CBL of 0.252 ± 0.175 mm and 0.251 ± 0.175 mm, respectively, compared with 0.173 ± 0.210 mm and 0.141 ± 0.172 mm in the mandible, with no significant difference. The success rate of dental implants at 12 months was 95% in the control group and 90% in the test group. Conclusion: Within the limitations of this study, it can be concluded that implants placed with the low-speed drilling protocol without saline irrigation exhibited a similar CBL compared with implants placed with the standard drilling protocol. However, a higher success rate was recorded especially in type 1–quality bone for the control group compared with the test group. Further randomized clinical trials with greater sample sizes and extended follow-up times should be performed to obtain stronger evidence and a better understanding of the influence of drilling speed on mean CBL and long-term implant success.

Background: Cancer patients may face challenges in their regular treatments and their quality of life (QoL) due to the coronavirus disease 2019 (COVID-19) outbreak. Objectives: The purpose of this study was to assess the QoL of cancer patients in Iran during the COVID-19 crisis. Methods: We applied the EORTC (European Organisation for Research and Treatment of Cancer) Core Quality of Life (QLQ-C30) questionnaire to measure the QoL of cancer patients in Rasoul Akram Hospital in 2021 in Tehran. Based on the inclusion criteria (a cancer diagnosis, being 18 years of age or older, and the ability to understand (but not necessarily read) the Persian language), 87 cancer patients were found to be eligible. Of these, 85 completed the questionnaire. We used SPSS to analyze the data with an independent t test and analysis of variance (ANOVA). Results: According to the result of the analysis, the global health status (main Qol score) was 55.49 ± 21.27. We found no significant difference in the global health status scores based on any demographic variables. Regarding functional scales, the type of insurance had a significant effect on the average cognitive functioning score (P-value = 0.043), with the highest score (79.37 ± 21.02) for patients with Medical Service Insurance and the lowest score (54.76 ± 29.99) for patients without insurance. We also found that in symptom scales, age (P-value < 0.001) and the type of cancer (P-value < 0.001) had a significant impact on the average appetite loss score. Conclusions: The QoL of cancer patients has deteriorated during the coronavirus outbreak in terms of general health status, functional scales, and symptom scales. Cancer patients need to be supported by decision-makers and hospital managers, especially in epidemics, to cope with psychological issues related to epidemics, such as fear, anxiety, and worry, and to ensure that they receive adequate services.

Purpose: When encountering a buccal bone defect during implant placement, guided bone regeneration (GBR) is a well-accepted method for bone reconstruction. However, it is still unclear if the esthetic and patient-reported outcomes are comparable to implants placed in native bone. The purpose of this prospective trial was to compare implants placed with a GBR procedure for a small (= 4 mm) buccal defect with implants placed completely in native bone (control). Materials and Methods: Patients were allocated to the GBR group or control group during implant placement in the esthetic zone. Implants were placed after at least 12 weeks of healing of the extraction sockets. A buccal bone defect of = 4 mm resulted in allocation to the GBR group. Follow-up was performed until 12 months after loading. Outcome measurements were as follows: esthetic scores, patient-reported outcome measurements, implant survival and complications, clinical indices, and radiographic measurements. Results: In total, 45 patients were included, of which 23 underwent a GBR procedure after implant placement, and in 22 patients no GBR was necessary. No significant differences in esthetic outcomes were seen between the two groups. At the final follow-up, a mean pink esthetic score (PES) of 7.8 (SD: 1.5) was seen for the GBR group and 8.4 (SD: 1.4) for the control group. Regarding the white esthetic score (WES), a mean of 9.1 (SD: 1.0) was found for both groups. Patients of both groups were equally satisfied with their mucosa and crown. A mean visual analog score (VAS) for the soft tissues of 8.6 (SD: 1.0) in the GBR group and 8.8 (SD: 0.9) for the control group was noted. A mean VAS of 9.2 (SD: 0.8) was noted for the crown in the GBR group and 8.6 (SD: 2.0) in the control group. Implant survival was 100%, and there were no significant differences in complications, plaque/bleeding/gingiva indices, width of attached mucosa, and marginal bone loss. Conclusion: Implants placed in the esthetic zone with GBR or complete native bone coverage showed successful esthetic outcomes and satisfied patients with predictable clinical and radiographic parameters after more than 1 year of loading. Within the limits of this study, GBR for a small buccal bone defect seems to be a reliable technique with good esthetics and patientreported outcomes. [ABSTRACT FROM AUTHOR]

Purpose: Autogenous bone grafts are considered a "gold standard." The success of autografts mainly depends on their ability to promote an osteogenic response. The aim of this study was to collect autogenous bone during implant osteotomy preparation using two different drilling protocols and to evaluate and compare the proliferation and differentiation ability of the collected bone particles. Materials and Methods: Autogenous bone particles were harvested from 20 patients during implant osteotomy preparation using two different drilling protocols: (1) standard drilling protocol with saline irrigation (according to the manufacturer's recommendation) and (2) low-speed drilling protocol without saline irrigation (speed < 200 rpm). Collected bone samples were cultured in growth medium, and after 2 to 3 weeks, cells that grew out from bone grafts were cultured in the normal medium as well as in osteogenic medium for days 0, 4, 7, and 20. Scanning electron microscopy, alizarin red/toluidine blue staining, DNA, ALP, and calcium content measurements were performed. Repeated measures analysis of variance (ANOVA) with Bonferroni's test was employed to analyze the data of this study. Results: The total DNA content was significantly higher for the low-speed drilling samples compared with the standard drilling on day 4 (P < .05), day 7 (P < .01), and day 20 (P < .001) in the normal medium and on day 7 (P < .01) and day 20 (P < .01) in the osteogenic medium. Besides, calcium measurements and mineralized matrix formation observed with alizarin red/toluidine blue staining were significantly higher for the low-speed drilling group compared with the standard drilling group. Conclusion: Osteogenic efficacy (differentiation and proliferation) of autogenous bone particles collected using low-speed drilling was superior compared with standard drilling samples.
