Comparison of Short-Term Restorative Effects and Periodontal Health Status of Restorations Made of Different Materials in Full-Crown Restoration of Mandibular Premolar Tooth Defects.

Purpose To compare the short-term restorative effect and periodontal health status of restorations with different materials in full-crown restoration of mandibular premolar tooth defects. Methods A total of 105 cases (123 affected teeth) of mandibular premolar tooth defects who visited the Department of Stomatology between January 2019 and January 2020 were selected, of which 58 cases (68 affected teeth) restored with cobalt-chromium alloy porcelain crowns were included in the metal-ceramic crown (MCC) group and 47 cases (55 affected teeth) repaired by zirconium dioxide all-ceramic crowns were assigned to the zirconia crown (ZC) group. The restorative effect, inflammatory factors (high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α)) and periodontal health indicators (human cartilage glycoprotein-39 (YKL-40), resistin, aspartate aminotransferase (AST), and alkaline phosphatase (ALP)) after treatment, and the occurrence of adverse reactions were compared between the two groups. Results The ZC group outperformed the MCC group in terms of margin fitness, restoration fracture, gingival condition, and color matching. After restoration, hs-CRP and TNF-α were statistically decreased in both groups, while YKL-40, resistin, AST, and ALP were significantly increased; and compared with the MCC group, hs-CRP, TNF-α, YKL-40, resistin, AST, and ALP were lower in the ZC group. The ZC group also scored statistically higher in retention effect, aesthetic effect, masticatory function, voice function, and comfort. Moreover, the ZC group had a higher total effective rate and a lower incidence of adverse reactions than the MCC group, with statistical significance. Conclusions Zirconia dioxide all-ceramic crowns contribute to a better short-term restorative effect in the full-crown restoration of mandibular premolar tooth defects, with little impact on periodontal health and high patient satisfaction, which deserves popularization and application.

ESTHETIC MANAGEMENT OF DEVELOPMENTAL ENAMEL DEFECT WITH RESIN INFILTRATION TECHNIQUE

Developmental defects cause color changes in enamel, compromising the esthetic appearance of the tooth and therefore affecting the child's quality of life. The resin inltration technique has shown a positive esthetic effect in the treatment of developmental enamel defects with different etiologies and is regarded as micro invasive procedure since only a small amount of enamel is removed in this procedure. The present paper reports the effectiveness of the resin inltration technique (Icon, DMG) in the management of localised enamel hypomineralisation of permanent teeth after trauma to the primary predecessor.

The Evanescence of Lyric: A Review of John Wilkinson’s Lyric in Its Times: Temporalities in Verse, Breath, and Stone

In Lyric in Its Times (2019), John Wilkinson reads lyric poetry for its “repeatable evanescence,” which Wilkinson characterizes as lyric poetry’s ability to initiate disruptive aesthetic events for its readers across historical moments. In order to suggest the dynamic lives that poems lead as aesthetic object-events, each chapter of Lyric in Its Times offers close readings that combine the analysis of poetic rhythm with attention to poems’ material rhetoric of stone, rock, and glass. Readings center on poets of the New York School and St. Ives, Cornwall but reach back to the Renaissance and often discuss poetry alongside visual art. Wilkinson sketches lyric poetry’s aesthetic forcefulness across time and elucidates how objects like stone contribute to aesthetic effects.

베트남 흐몽(Hmong) 복식 트리밍의 미적 효과에 관한 연구

The Vietnamese Hmong have developed their own clothing culture, and their creativity is well expressed, especially in terms of decoration. Despite the unique decorative characteristics of Vietnamese Hmong clothing, research on it is insufficient, so there is a need for specific research on the decorative aspects expressed in Vietnamese Hmong costumes. This study aims to provide essential information on ethnic costumes by focusing on the decorative trimming of Vietnamese Hmong costumes, examining the expression types and characteristics, and understanding the aesthetic effects.

Digital Sensory Marketing Factors Affecting Customers’ Intentions to Continue Organic Online Purchases during COVID in India

Myriad studies have examined the effect of web aesthetics on consumer purchases. However, customers’ intention to continue organic beauty products online purchases during COVID in the Indian context has received little attention. The purchase of beauty products has been perceived as a non-essential product category during COVID times, especially in developing markets like India. The goal of this research is to present an integrated theoretical framework, extending the stimulus-organism-response (SOR) theory to determine the factors that influence the intention to continue organic beauty purchases during COVID times. Specifically, the role of artificial intelligence/virtual reality (AI/VR) based sensory-enabling technologies (SET) web aesthetics. We performed in-depth semi-structured interviews of 136 customers of 7 organic beauty brands in India. The results based on thematic analysis (using NVIVO) and MCA analysis indicates that telepresence, audiovisual (AV) congruency, dynamism, local robotics and ethnic chatbots are associated with SET-based web aesthetics. On the other hand, the country of origin, source, ingredient, nature, control, sense of belonging and dominance are associated with traditional web aesthetics. Based on the extended SOR research model, a future research agenda comprising four propositions has been drawn.

IMMEDIATE RESULT OF ICON INFILTRATION IN WHITE SPOT LESIONS CAUSED BY FLUOROSIS: A CASE REPORT

The Icon technique is designed to effectively restore non-cavitary lesions (porosity in deor hypomineralized enamel). Infiltration of the composite resin increases the strength of demineralized enamel. The results of clinical application indicate the effectiveness of the Icon infiltration method in combination with microabrasion and professional whitening, as well as an excellent aesthetic effect for 2 years after treatment.
 The Icon method may be a minimally invasive alternative to various methods of remineralization, especially in pediatric practice. Certain limitations in the application of the Icon method include its relatively high cost.
 This publication presents favorable treatment outcomes, obtained within a short time, in the therapy of fluorosis of permanent incisors in a 7-year-old girl after the application of the Icon infiltration method. This clinical case may be of practical interest to dentists in the wider use of this technique in pediatric dentistry, especially in the regions of endemic fluorosis. Before disseminating the results of the treatment, we obtained written informed consent from the patient's mother.
 We used the Icon infiltration method and obtained fast and reliable results, which was a key aspect to choose the treatment approaches in this clinical case.
 There were no restrictions as to the application of this approach in this clinical case. In the scientific literature, there is an unconfirmed theory that the prevalence of fluorosis and its severity increases over time after tooth eruption. However, recent studies have shown that very mild and moderate fluorosis tends to decrease in severity in adolescence. This trend continues into young adulthood and then slows down at the age of twenty. Given this information, the clinical effect reported by the manufacturers after treatment with Icon might be even longer than the declared period of 2 years after treatment for fluorosis.

Surgical Correction of Ectropion: Comparison Between Full Thickness Skin Grafts and Local Flaps

Objective: To compare the effectiveness of two reconstruction techniques, i.e., full-thickness skin graft and local flap, for patients undergoing reconstructive surgery for ectropion repair.
 Study Design: Prospective comparative study.
 Place and Duration of Study: Department of Plastic & Reconstructive Surgery, Dr Ruth K.M. Pfau Civil Hospital Karachi, from Feb to Aug 2020.
 Methodology: The study was conducted after acquiring approval from the Institutional Review Board of Dow University of Health Sciences. Patients advised repairing ectropion were admitted to the ward prior to a day or night of the procedure. The consultant surgeon decided on the operative management, either using a full-thickness skin graft or a local flap, depending on the type of ectropion.
 Results: 60 patients were recruited for the study, with 30 patients in each group. At follow-up of two weeks, one month, and three months’ skin colour match and pliability were significantly better in patients who received local flap than those treated with a full-thickness skin graft. Out of 30, 2 (6.7%) patients developed ectropion recurrence when they received full-thickness skin graft coverage, whereas ectropion recurrence was not observed in patients managed with local flap.
 Conclusion: Local flap appears to be more effective than full-thickness skin graft in achieving excellent aesthetic effects in patients who underwent correction of ectropion.

Computational Analysis Problem of Aesthetic Content in Fine-Art Paintings

The article discusses the possibilities of the formal analysis of the fine-art painting composition on the basis of the classical definitions of beauty and computational aesthetics’ approaches of the second half of the 20th century he authors define the problem and consider solutions for the formalization of aesthetic perception in the context of aesthetic text, i.e., as part of the fine arts composition – a formal sequence of signs simply ordered in accordance with the syntactic rules’ system. The methodology of the research is defined by the general semiotics, distinguishing semantics, syntax, and pragmatics of a sign, by the aesthetic analysis’ methods, ranging according to the author’s message aesthetics, receptive aesthetics, and text aesthetics, as well as by the computational analysis methods connected with neural network means of defining the images’ symmetry. The article reveals preconditions for the emergence and also the current state of computational aesthetics as an interdisciplinary branch of knowledge. Analyzing the problem from the perspective of philosophy, aesthetics, semiotics, and technology, the authors draw attention to the need to improve the computational aesthetics methods. Firstly, the existing methods do not always enable to describe the fine-art object adequately. Secondly, there exists the so-called reduction of aesthetic assertion transforming it into the assertion concerning the object’s external characteristics. As a result, the authors assume that the increasing complexity of the current mathematical models and the experts’ subjective assessment support will allow to reach a compromise solution that enables the development of computational aesthetics as a branch of knowledge. Enhancement and development of the mathematical models, taking into account the rules of semiotics and subjectivism of the human perception, is the relevant objective of computational analysis of the aesthetic fine-arts text. The results of the present research supports the classic statement regarding the underivability of semantic and pragmatic propositions from syntax. The research concludes that relevant objectives are to find a correlation between, one the one hand, the axes and points of symmetry, deriving from the neural simulation, and, on the other hand, aesthetic effect, emerging from the perception of fine-art paintings.

In Vivo Evaluation of the Effects of Sintering Temperature on the Optical Properties of Dental Glass-Ceramics.

In prosthodontics, the ability of glass-ceramics to express the optical properties of natural teeth is an important goal of esthetic restorations. Dental restorations do not merely need to be similar in color to natural teeth; proper optical properties, such as opalescence, transparency, etc., must be combined in order to achieve excellent esthetic effects. The optical properties of ceramic materials are mainly distinguished by different hues (e.g., A, B, C, and D) combined with translucency (e.g., high translucency (HT), medium translucency (MT), low translucency (LT), and medium opacity (MO)). However, there are many varieties of tooth color. Therefore, it is expected that glass-ceramics can change their nanocrystal size and porosity through different heat-treatment temperatures and times and, thereby, present different transparency effects. This study mainly analyzed the influence of changes in sintering temperature on the optical properties of glass-ceramics. The optical properties of glass-ceramics in the oral cavity were evaluated with human trials. We hypothesized that (1) the transparency of glass-ceramics can be changed by controlling the sintering temperature and (2) glass-ceramics modified by the sintering temperature can be suitable for clinical applications. Results showed that the transparency decreased, the nanoparticle size increased, the crystallinity increased, and the surface hardness decreased as the sintering temperature increased. High-brightness glass-ceramics have more-sensitive optical properties. Results of clinical trials showed that glass-ceramics whose transparency was changed by controlling the sintering temperature can be candidates for clinical applications. Based on the above results, the hypotheses of this study were supported. In the future, we will continue to explore the esthetic field of dental restorations.

The Technical Semantic Structure of the Will of al-Alama al-Hilly to his son Fakhrul Muhaqiqin Stylistic Study

The will generally takes the direction of guidance and instruction, and is based on life experiences in which the author concludes his judgments on life matters. However, though the will of the al-Alama al-Hilly to his son Fakhrul Muhaqiqin is full of preaching and evidence and is rich in the methods of argument and persuasion, but we try to study it stylistically. The will has different stylistic traits on which the author (devisor) relies in order to influence the devisee. In this sense, we monitor the stylistic features of the text through the phonetic, semantic and syntactic levels and joining all that to the intellectual innovation of the al-Alama al-Hilly. The study deals with the morphological forms and their semantic effect, the phonetic rhythm in the text, the structure and its semantic effect (deletion, objection, contradiction...) to conclude that in addition to the religious and moral ideas in the text of the will. It carries the stylistic features that enrich its rhetoric status and affect the recipient due to its aesthetic effect that establishes its guiding and instructional content.

Immediate versus Delayed Implantation for Single-Tooth Restoration of Maxillary Anterior Teeth: A Comparative Analysis on Efficacy.

Objective The present research is aimed at determining the efficacy of immediate implantation (II) and delayed implantation (DI) for single-tooth restoration of maxillary anterior teeth. Methods From February 2019 to June 2020, 80 patients who received single-tooth restoration of maxillary anterior teeth in Suzhou Kowloon Hospital, Shanghai Jiaotong University School of Medicine, were included, among which 38 cases with DI restoration were used as the control group (CG), and the remaining 42 cases with II were used as the research group (RG). The complications that occurred were recorded. Besides, subjective satisfaction (Visual Analogue Scale (VAS)), aesthetic effect after anterior teeth trauma restoration (Pink Esthetic Score (PES)), aesthetics of dental hard tissue (White Esthetic Score (WES)), pocket depth assessed by pure titanium periodontal probe, implant stability (Implant Stability Quotient (ISQ)), and oral health-related quality of life (Oral Health Impact Profile- (OHIP-) 14) were evaluated. Attachment height, general look, color, and chewing function were all much higher in RG than in CG, according to the evaluation results. Furthermore, at 3 months, 6 months, and 12 months after surgery, RG had greater PES, WES, ISQ, and OHIP-14 scores, while the periodontal depth was decreased. In both groups of patients, the incidence of complications was similar, with no discernible differences.

A present from the forest: Focus group interviews on cancer survivors’ forest experiences

ObjectiveTo explore cancer survivors' forest experiences and to understand the relevance of these experiences from their perspectives in the context of the growing interest in nature's impact on health and quality of life. MethodsFrom July 29 to August 12, 2021, four focus group interviews were conducted with cancer survivors who visited forests in South Korea. The data were analyzed using qualitative content and thematic analysis. ResultsThe participants were 21 female cancer survivors with a mean age of 58.4 (age range 44–69) years. The focus group interviews revealed three themes and 10 sub-themes regarding subjective perceptions and experiences related to forests. The overarching themes were as follows: (1) awakened bodily senses and fascination with the forest; (2) remedial effect; and (3) a source of inspiration. These three themes capture the impact of forest experiences on participants’ lives and the value they derived from these experiences. The participants considered these experiences a gift from forests. In particular, they experienced aesthetic enrichment and restorative effects such as boosted energy levels, reduced fatigue, and a buffer against mood swings. Finally, forests were a source of inspiration that led the participants toward personal growth. ConclusionsBy gaining a better understanding of survivors' forest experiences, we identified that forest-based interventions for supportive cancer care can align with patients’ values and preferences and serve as a secure space where they can feel cared for. This study can contribute to the development of forest-based interventions for cancer survivorship care.

Managing early childhood caries with silver diamine fluoride in the COVID-19 context: case report

COVID-19 is challenging modern dentistry, obliging all professionals to look for treatment strategies that are in accordance with health and ethical standards, so as to avoid virus transmission in the dental office. In recent years, paediatric dentistry has benefited from minimally invasive techniques to prevent and treat early childhood caries. Silver diamine fluoride (SDF) is a material that follows this philosophy because it provides professionals preventive and arresting actions for carious lesions in a practical and effective way. The present case details the management of a preschool-age patient who attended the dental office due to an emergency during the pandemic. The patient's emergency was resolved, but due to the diagnosis of severe early childhood caries, other mild and moderate carious, lesions were managed with SDF with the objective of avoiding future pulpal lesion development. The aim of this case is to raise awareness among dentists who treat children to consider the biological benefits of SDF in situations, such as the current contingency, as well as the benefits of mitigating the aesthetic effects thanks to the use of potassium iodide. CPD/Clinical Relevance: The use of silver diamine fluoride in a paediatric patient with early childhood caries is highlighted.

Хирургическое лечение Hallux extensus

Introduction This study is a comparative assessment of early and long-term results of two different methods of surgical treatment of hallux extensus. Materials and methods The results of surgical treatment of 22 patients with Hallux extensus at the orthopedic department of the Moscow Yudin City Hospital from 2017 to 2019 were studied. The patients were divided into 2 groups depending on the tactics of surgical treatment. The main goal of this study is a comparative assessment of the functional results of two surgical techniques. The first group of patients, which included 11 subjects, underwent needle percutaneous tenotomy of the extensor tendon of the big toe, the second group, which also consisted of 11 people, underwent tenodesis of the tendon-muscular part of the short flexor of the big toe according to the proposed by us technique. Results The study results are based on the assessment of subjective patient satisfaction and radiography images, as well as on the ACFAS score. In the group of patients who underwent percutaneous tenotomy of the extensor tendon of the big toe, there was a recurrence of deformity in 4 patients (36 %) and insufficient correction of the deformity in 2 patients (18 %). In the group of patients who underwent tenodesis of the tendon-muscle part of the short flexor of the big toe, 100 % showed good functional results, pain relief and esthetic effect. Good treatment results were observed in 73.3 % of the patients. Conclusions Analysis of the clinical results of surgical treatment showed a high efficacy of tenodesis of the tendon-muscle part of the short flexor of the big toe in comparison with percutaneous tenotomy of the extensor tendon of the big toe. Positive results were achieved in 100 % of cases. No recurrence of deformity was observed. The patients did not complain of pain, and there were no problems with footwear in the postoperative period.

Zastosowanie licówek o minimalnie inwazyjnej preparacji „no-prep” – praca poglądowa

Aesthetics is often the main reason for a patient to come to a dentist’s office. The desire to have a beautiful smile, with the awareness in society of the need to protect healthy tooth tissues, requires from the doctor to properly plan and carry out the treatment process. Modern dental prosthetics, should restore lost tissues, restore the function of the stomatognathic system and aesthetics, as well as follow the principles of minimal invasiveness of the procedures performed. The use of veneers in prosthetic rehabilitation allows an aesthetic reconstruction of lost, missing or discolored tooth tissues, reducing the risk of losing the tooth structure during preparation. Veneers with minimally invasive preparation i.e. no-prep are one of the possibilities of rehabilitation of patients, allowing for a satisfactory aesthetic effect with a slight reduction of tooth tissues. The use of these restorations is possible thanks to the progress made in the field of ceramics and the possibility of using thin veneers. Correct diagnostics, treatment planning, selection optimal material depending on clinical indications, precise laboratory and clinical stages of prosthetic restoration allow to achieve therapeutic success.

“Something Is Happening”: Medical Realism and the Problem of Acting in Harold Pinter’s A Kind of Alaska

Harold Pinter’s A Kind of Alaska outlines and responds to a critical dilemma in the relationship between modern drama and medical practice. Focusing on a clinical encounter between a doctor and a patient, Pinter’s play was inspired by a real-life medical case history taken from neurologist Oliver Sacks’s Awakenings. Its engagement with medical reality, however, is disturbed by the aesthetic effects of Pinteresque dramaturgy, which subtly undermine the play’s presentation of bioethical dilemmas that are determined by authoritative acts of diagnosis and the control of doctor-patient communication. Reviewing the history of medical vision alongside theatrical realism reveals a paradoxical emphasis on pedagogy and unlearning within both traditions, wherein naïve acts of empiricism and a dutiful adherence to material presence are meant only to reinforce prescribed conclusions and extant structures of knowledge. A Kind of Alaska responds to this paradox by eliciting mutually exclusive attitudes toward narrative and acting, juxtaposing realist effects with those borrowed from the Brechtian Lehrstücke. As a result, the play challenges the kinds of closure implicit in both clinical vision and history, prioritizing instead the dialectical indeterminacies necessary to both the learning and the practice of medicine.

Study of Al–SiO2 Aesthetic Composite Coating on Orthodontic Metal Archwire

Nickel–titanium orthodontic wires (NTWs) play an essential role in orthodontic treatment. However, their corrosion and aesthetic properties limit their applications. To improve the aesthetic effects of nickel–titanium orthodontic archwires, we prepared aluminium–silicon dioxide (Al–SiO2) as a biocompatible layer coated onto the NTWs. The Al–SiO2 coating was first fabricated using physical vapor deposition magnetron sputtering, and its physicochemical and biocompatibility properties were investigated. Al–SiO2 layers were well coated on the NTWs. The corrosion currents in the nickel–titanium (NiTi) control, Al–SiO2-coated NiTi experimental, stainless steel (SS) control and Al–SiO2-coated SS experimental groups were 23.72 μA cm−2, 1.21 μA cm−2, 0.22 μA cm−2 and 0.06 μA cm−2, respectively. Al–SiO2-coated NTWs with reduced corrosion current density indicated that the preparation of Al–SiO2 coating on the surface of NiTi and SS could reduce the tendency of electrochemical corrosion. The friction coefficients of orthodontic wires in the NiTi control, NiTi experimental, SS control, and SS experimental groups were 0.68, 0.46, 0.58 and 0.45, respectively. A low friction coefficient was observed in the Al–SiO2-coated NTWs, and the reduced friction coefficient improved the efficiency of orthodontics. Furthermore, the excellent biocompatibility of the NTWs and SS coated with Al–SiO2 indicates that Al–SiO2 as a novel aesthetic layer could improve the physicochemical properties of NTW and SS without causing cytotoxicity, which has considerable potential for modification of NTW and SS surfaces.

Role of implant loading time in the prevention of marginal bone loss after implant-supported restorations: A targeted review.

The implant-supported restoration of missing teeth is a recognized method of treatment that ensures a functional, esthetic and durable effect, along with patient satisfaction. However, the preferable time of dental implant loading is under debate. Currently, 3 protocols are used: immediate loading; early loading; and conventional (late) loading. Immediate loading provides benefits such as short treatment time, the elimination of the second surgery required for later loading protocols, the protection of the gingival papilla, an immediate esthetic effect, and high patient satisfaction. This review aimed to summarize the evidence on the impact of loading time on marginal bone loss (MBL) around dental implants, which is considered a useful measure of implantological treatment effects. A literature search was conducted based on the PubMed/MEDLINE database. The search focused on studies providing the MBL values by protocol. Out of the 1,366 hits received in the initial search, 10 studies were included in the qualitative analysis. At 12 months, the MBL range was 0.17-1.86 mm in patients undergoing the immediate protocol, 0.14-1.22 mm in patients undergoing the early protocol, and 0.44-0.91 mm in patients undergoing the late protocol. The studies were heterogeneous, but no significant differences in the occurrence of MBL were reported between the immediately and early loaded implants as compared with the conventionally loaded ones. Further studies are needed to determine other factors that might be related to the type of protocol, important for optimal patient treatment.

Aesthetic multimodality of speech and gesture: Towards its functional framework

The study develops a functional multimodal approach to speech and gesture behavior to explore aestheticism in more and less staged discourse of cinema and interview. We hypothesize that cinema and interview employ the same communicative functions; however, these functions constitute different frameworks which contribute to the higher aesthetic potential of cinema. This approach allows to study the aesthetic via communicative functions frameworks in multimodal discourse. To establish the function frameworks in cinema and interview, we apply a contrastive functional analysis of speech and gesture in the highly ranked actors’ argumentative and descriptive monologues. With the help of variance and regression analysis, we explore the distribution of pragmatic and discourse-structuring functions (with sub-functions) in speech as contingent on pragmatic, deictic, representational and adaptive functions of gestures. The study confirms that cinematic discourse exploits fewer deictic, representational and adaptive gesture functions, whereas pragmatic gesture functions (especially emphatic ones) appear more frequently and are contingent on several pragmatic and discourse-structuring functions of argumentative and descriptive speech. Interview function frameworks display lower predictability, which shows higher spontaneity of gestures; however, there are specific gestures typical of interview (self-adaptors) which may serve as indicators of pragmatic functions of argumentation. The study also manifests individual variations within the function frameworks. Overall, cinema and interview display variance in replication and regularity of speech and gesture functions, which presumably helps create higher and lower aesthetic effects.

Counterfactual Reasoning in Art Criticism

Abstract When we evaluate artworks, we often point to what an artist could have done or what a work could have been in order to say something about the work as it actually is. Call this counterfactual reasoning in art criticism. On my account, counterfactual claims about artworks involve comparative aesthetic judgments between actual artworks and hypothetical variations of those works. The practice of imagining what an artwork could have been is critically useful because it can help us understand how artworks achieve specific aesthetic effects. I conclude by responding to an objection to my account on the basis that it violates the widely accepted acquaintance principle in aesthetics, on which aesthetic judgments must be based on firsthand perceptual encounters with their objects.
