The impact of oral erythritol on subsequent energy intake is unknown. The aim was to assess the effect of oral erythritol compared to sucrose, sucralose, or tap water on energy intake during a subsequent ad libitum test meal and to examine the release of cholecystokinin (CCK) in response to these substances. In this randomized, crossover trial, 20 healthy volunteers received 50 g erythritol, 33.5 g sucrose, or 0.0558 g sucralose dissolved in tap water, or tap water as an oral preload in four different sessions. Fifteen minutes later, a test meal was served and energy intake was assessed. At set time points, blood samples were collected to quantify CCK concentrations. The energy intake (ad libitum test meal) was significantly lower after erythritol compared to sucrose, sucralose, or tap water (p < 0.05). Before the start of the ad libitum test meal, erythritol led to a significant increase in CCK compared to sucrose, sucralose, or tap water (p < 0.001). Oral erythritol given alone induced the release of CCK before the start of the ad libitum test meal and reduced subsequent energy intake compared to sucrose, sucralose, or tap water. These properties make erythritol a useful sugar alternative.

Zinc (Zn) plays an important role in metabolic homeostasis and may modulate neurological impairment related to obesity. The present study aimed to evaluate the effect of Zn supplementation on the intestinal microbiota, fatty acid profile, and neurofunctional parameters in obese male Wistar rats. Rats were fed a cafeteria diet (CAF), composed of ultra-processed and highly caloric and palatable foods, for 20 weeks to induce obesity. From week 16, Zn supplementation was started (10 mg/kg/day). At the end of the experiment, we evaluated the colon morphology, composition of gut microbiota, intestinal fatty acids, integrity of the intestinal barrier and blood–brain barrier (BBB), and neuroplasticity markers in the cerebral cortex and hippocampus. Obese rats showed dysbiosis, morphological changes, short-chain fatty acid (SCFA) reduction, and increased saturated fatty acids in the colon. BBB may also be compromised in CAF-fed animals, as claudin-5 expression is reduced in the cerebral cortex. In addition, synaptophysin was decreased in the hippocampus, which may affect synaptic function. Our findings showed that Zn could not protect obese animals from intestinal dysbiosis. However, an increase in acetate levels was observed, which suggests a partial beneficial effect of Zn. Thus, Zn supplementation may not be sufficient to protect from obesity-related dysfunctions.

Published: September 2022

Background: Vitamin D is considered to modulate T-cell function, which has been implicated in the treatment of inflammatory conditions. However, there is limited knowledge on the effects of vitamin D and its influences on circulating T-cell profiles in humans, particularly in overweight Black individuals who are more likely to be vitamin D insufficient (serum 25(OH)D concentrations of ≤20 ng/mL). Thus, this study tested the hypothesis that vitamin D supplementation modulates T-cell composition, which is in a dose-dependent manner. Methods: A 16-week randomized, double-blinded, placebo-controlled trial of vitamin D3 supplementation was undertaken in 70 overweight/obese Black people (mean age = 26 years, 82% female) with 25 hydroxyvitamin D ≤ 20 ng/mL at baseline. Subjects were randomly assigned a supervised monthly oral vitamin D3 equivalent to approximately 600 IU/day (n = 17), 2000 IU/day (n = 18), 4000 IU/day (n = 18), or a placebo (n = 17). Fresh peripheral whole blood was collected and CD3+, CD4+ and CD8+ cell counts and percentages were determined by flow cytometry at baseline and at 16 weeks, among 56 subjects who were included in the analyses. Results: A statistically significant increase in CD3+% in the 2000 IU/day vitamin D3 supplementation group, and increases in CD4+% in the 2000 IU/day and 4000 IU/day vitamin D3 supplementation groups were observed (p-values < 0.05) from the changes in baseline to 16 weeks. Further adjustments for age, sex and BMI showed that 2000 IU/day vitamin D3 supplementation increased in CD3+ count, CD3%, CD4 count, and CD4%, as compared to the placebo group (p-values < 0.05). Moreover, the highest serum 25(OH)D quantile group had the highest CD3% and CD4%. Conclusions: Sixteen-week vitamin D3 supplementation increases peripheral blood T-cell numbers and percentages in overweight/obese Black patients with vitamin D insufficiency. This resulting shift in circulating T-cell composition, particularly the increase in T helper cells (CD4+ cells), suggests that vitamin D supplementation may improve immune function in Black individuals.
Nanoparticle-Based Drug Delivery Systems Targeting Tumor Microenvironment for Cancer Immunotherapy Resistance: Current Advances and Applications

Published: September 2022

Cancer immunotherapy has shown impressive anti-tumor activity in patients with advanced and early-stage malignant tumors, thus improving long-term survival. However, current cancer immunotherapy is limited by barriers such as low tumor specificity, poor response rate, and systemic toxicities, which result in the development of primary, adaptive, or acquired resistance. Immunotherapy resistance has complex mechanisms that depend on the interaction between tumor cells and the tumor microenvironment (TME). Therefore, targeting TME has recently received attention as a feasibility strategy for re-sensitizing resistant neoplastic niches to existing cancer immunotherapy. With the development of nanotechnology, nanoplatforms possess outstanding features, including high loading capacity, tunable porosity, and specific targeting to the desired locus. Therefore, nanoplatforms can significantly improve the effectiveness of immunotherapy while reducing its toxic and side effects on non-target cells that receive intense attention in cancer immunotherapy. This review explores the mechanisms of tumor microenvironment reprogramming in immunotherapy resistance, including TAMs, CAFs, vasculature, and hypoxia. We also examined whether the application of nano-drugs combined with current regimens is improving immunotherapy clinical outcomes in solid tumors.

The process of wound healing is a tightly controlled cascade of events, where severe skin wounds are resolved via scar tissue. This fibrotic response may be diminished by applying anti-fibrotic factors to the wound, thereby stimulating regeneration over scarring. The development of tunable biomaterials that enable spatiotemporal control over the release of anti-fibrotics would greatly benefit wound healing. Herein, harnessing the power of click-to-release chemistry for regenerative medicine, we demonstrate the feasibility of such an approach. For this purpose, one side of a bis-N-hydroxysuccinimide-trans-cyclooctene (TCO) linker was functionalized with human epidermal growth factor (hEGF), an important regulator during wound healing, whereas on the other side a carrier protein was conjugated—either type I collagen scaffolds or bovine serum albumin (BSA). Mass spectrometry demonstrated the coupling of hEGF–TCO and indicated a release following exposure to dimethyl-tetrazine. Type I collagen scaffolds could be functionalized with the hEGF–TCO complex as demonstrated by immunofluorescence staining and Western blotting. The hEGF–TCO complex was also successfully ligated to BSA and the partial release of hEGF upon dimethyl-tetrazine exposure was observed through Western blotting. This work establishes the potential of click-to-release chemistry for the development of pro-regenerative biomaterials.

Published: September 2022

Wood–plastic composite (WPC) is a kind of composite material that is made of plastic and wood fiber or wood powder. Because it is mothproof, is resistant to corrosion, and has plasticity, among other advantages, it has been researched and used increasingly in building materials. The flexural property of WPC is an important subject in evaluating its mechanical properties. In this paper, wood–plastic raw materials and processing technology are introduced; the internal and external factors of WPC which affect the flexural properties are analyzed; the different ways of enhancing the bending capacity, including the surface pretreatment, addition of different modifiers (compatibility agent and coupling agent) etc. are summarized; and the methods of operation and strengthening effect are analyzed. This work provides a reference for further research in related fields.

Published: September 2022

The aim of this study is to compare the adhesive interface formed in dentin, using self-adhesive composites applied with different bonding strategies, by testing the microtensile bond strength (μTBS) and ultramorphology through the use of light microscopy. Permanent, sound human molars were randomly allocated to six experimental groups. The groups included a negative control group, where only etching was performed via EtchOnly; a positive control group where an adhesive was applied, OptiBondFL (OBFL); and an experimental group where a primer was applied using a co-curing strategy together with a composite (Primer_CoCuring). The samples were sectioned into microspecimens for μTBS (n = 8) and into 1-mm thick slabs for light microscopy using Masson’s trichrome staining protocol (n = 3). The statistical analysis included a two-way ANOVA for μTBS data and Tukey’s HSD was used as a post-hoc test (significance level of 5%; SPSS v. 26.0). The results of the μTBS revealed that the self-adhesive composite (F = 6.0, p < 0.018) and the bonding strategy (F = 444.1, p < 0.001) significantly affected the bond strength to dentin. However, their interactions were not significant (F = 1.2, p = 0.29). Etching dentin with no additional treatment revealed the lowest μTBS (VF_EtchOnly = 2.4 ± 0.8 MPa; CC_EtchOnly = 2.0 ± 0.4 MPa), which was significantly different from using a primer (VF_CoCu = 8.8 ± 0.8 MPa; CC_CoCu = 6.3 ± 1.0 MPa) or using the full adhesive (VF_OptiBondFL = 22.4 ± 0.3 MPa; CC_OptibondFL = 21.2 ± 0.4 MPa). Microscopy images revealed that the experimental Primer_CoCuring was the only group with no collagen fibers exposed to the dentin–composite interface. Overall, the use of a primer, within the limitations of this study, increased the bonding of the self-adhesive composite and provided sufficient infiltration of the collagen based on light-microscopic imaging.

Published: September 2022

The quantitative relationship between the fraction of UV exposure energy and the retention fraction of tensile strength was investigated on the m-Aramid/p-Aramid blend ratio of spun yarn. An exponential equation to calculate tensile strength from an arbitrary UV exposure energy is evaluated for yarns and fabrics. The spun yarns were exposed to UV light using a xenon-arc weathering meter. The retention fraction of tensile strength decreased exponentially with increasing the fraction of UV exposure energy. Curve fitting of the retention fraction of tensile strength to the fraction of UV exposure energy revealed two groups of degradation coefficients based on the blending ratio of m-Aramid/p-Aramid. The correlation between the degradation coefficients (αy and αf) of spun yarn and fabrics can be linearly regressed. The constant of proportionality in linear regression is considered to be the gap between the structure and the breaking mechanism of the fabric relative to yarn breakage. Based on the correlation between the degradation coefficients of spun yarn and fabrics and a mathematical model of the tensile strength of the spun yarn, the tensile strength of fabrics at a given UV exposure energy can be estimated from the tensile strength of the yarn.
Utilization of Polymeric Materials toward Sustainable Biodiesel Industry: A Recent Review

Published: September 2022

The biodiesel industry is expanding rapidly in accordance with the high energy demand and environmental deterioration related to the combustion of fossil fuel. However, poor physicochemical properties and the malperformance of biodiesel fuel still concern the researchers. In this flow, polymers were introduced in biodiesel industry to overcome such drawbacks. This paper reviewed the current utilizations of polymers in biodiesel industry. Hence, four utilizing approaches were discussed, namely polymeric biodiesel, polymeric catalysts, cold-flow improvers (CFIs), and stabilized exposure materials. Hydroxyalkanoates methyl ester (HAME) and hydroxybutyrate methyl ester (HBME) are known as polymeric biodiesel sourced from carbon-enriched polymers with the help of microbial activity. Based on the literature, the highest HBME yield was 70.7% obtained at 10% H2SO4 ratio in methanol, 67 °C, and 50 h. With increasing time to 60 h, HAME highest yield was reported as 68%. In addition, polymers offer wide range of esterification/transesterification catalysts. Based on the source, this review classified polymeric catalysts as chemically, naturally, and waste derived polymeric catalysts. Those catalysts proved efficiency, non-toxicity, economic feasibility, and reusability till the 10th cycle for some polymeric composites. Besides catalysis, polymers proved efficiency to enhance the biodiesel flow-properties. The best effect reported in this review was an 11 °C reduction for the pour point (PP) of canola biodiesel at 1 wt% of ethylene/vinyl acetate copolymers and cold filter plugging point (CFPP) of B20 waste oil biodiesel at 0.08 wt% of EVA copolymer. Polymeric CFIs have the capability to modify biodiesel agglomeration and facilitate flowing. Lastly, polymers are utilized for storage tanks and auto parts products in direct contact with biodiesel. This approach is completely exclusive for polymers that showed stability toward biodiesel exposure, such as polyoxymethylene (POM) that showed insignificant change during static immersion test for 98 days at 55 °C. Indeed, the introduction of polymers has expanded in the biodiesel industry to promote green chemistry.

Samples in the form of cylindrical plates, additively manufactured using the fused deposition modelling (or filament freeform fabrication, FDM/FFF) technology from polylactide (PLA), polyethylene terephthalate glycol (PETG) and polyetheretherketone (PEEK), were studied in series of in-vitro experiments on the adhesion of rat bone-marrow cells and rat peritoneal cells. Methods of estimation of the absolute number of cells and polymer samples’ mass change were used for the evaluation of cells adhesion, followed by the evaluation of cell-culture supernatants. The results of experiments for both types of cells demonstrated a statistically significant change in the absolute number of cells (variation from 44 to 119%) and the weight of the polymer samples (variation from 0.61 to 2.18%), depending on roughness of sample surface, controlled by a nozzle diameter of a 3D printer as well as printing layer height. It was found that more cells adhere to PLA samples with a larger nozzle diameter and layer height. For PETG samples, the results did not show a clear relationship between cell adhesion and printing parameters. For PEEK samples, on the contrary, adhesion to samples printed with a lower nozzle diameter (higher resolution) is better than to samples printed with a larger nozzle diameter (lower resolution). The difference in results for various polymers can be explained by their chemical structure.

Published: September 2022

This review analyzes the processes of phenotypic and morpho-biometric characterization of West African local chicken. Data were collected on a set of 44 articles, and other reference documents were used to analyze and discuss the data collected. Existing studies on the phenotypic and molecular characterization of local chicken populations in West Africa indicate the presence of a wide variety of plumage colors and conformations, and intra-population genetic diversity. However, none of these studies have been able to identify the existence of a differentiated subpopulation that can be assimilated into a distinct race. The conclusions of this studies are not sufficient to ensure the non-existence of “race” in West Africa because many of these studies focus only on the phenotypic aspect, while molecular characterization makes it possible to identify differentiated populations with certainty. Additionally, the populations studied are often small in size, though remaining within the FAO recommendation standards. The spatial distribution used to compare the subpopulations was based on agroecological zones with strong interconnections to and shared with West African human populations, to the detriment of socio-cultural realities. In order to be more effective and conclusive, characterization work could consider the spatial distance of subpopulations in a comparison and the levels of exchange between the human communities from which these chicken subpopulations originate.

The article presents the results of a hygienic study to assess the chemical contamination of soils in residential areas of Primorsky Krai based on the results of social and hygienic monitoring from 2018 to 2020. The analysis of the actual concentrations of heavy metals in the soil was carried out for 7 chemical elements: lead, zinc, copper, nickel, cadmium, manganese, mercury in 12 administrative territories of the region. Soil safety control points are certified using a system of geoinformation technologies. It has been established that a feature of the administrative territories of the northern part of the region is a sharp predominance of natural sources of chemical pollution over all others. Contamination with toxic elements of soils in the southern part of the region, especially in places of compact residence of the population, is of a pronounced technogenic character. The leading mechanism for the accumulation of microelements in the soils of the cities of Primorsky Krai is their intake from the atmospheric air, heavily polluted by man-made emissions, the leading sources of which are motor vehicles, railroad and sea transport.
Roman helmets with a browband shaped as a vertical fronton
Authors: NEGIN Andrei
Published: September 2022

Roman propaganda monuments are known best of all and they are still often cited, especially in Hollywood blockbusters. Despite the many doubts expressed by modern researchers, they continue to be sources valuable in many aspects as those monuments, mostly located in the capital, show how military weapons were perceived by the inhabitants of the capital, including the sculptors who were working on these monuments. There are many images of so-called Attic helmets on Roman monuments dated back to the first two centuries AD. As a rule, all of them are richly decorated with embossed floral ornament, have a browband with volutes in the temporal region and equipped with longitudinal crests with gorgeous plumes. The question arises, what are the samples were depicted on the Roman reliefs? How accurately this specimen have been reproduced by artists and sculptors, or, perhaps, we see only a reflection of the Hellenistic artistic tradition? There are helmets with a browband shaped as a vertical fronton with volutes existed. Their later modification is presented by finds from Guisborough, Theilenhofen, Chalon-sur-Saône. The pieces of the Ist century AD – early IInd century AD are Weiler-type helmets with a decorated riveted browband. They are the helmets from Nijmegen, Brza Palanka and from other places. The pieces from Butzbach and Hallaton can be considered as a transitional design between early and later helmet modifications with a vertical fronton. Thus, all of the above finds suggest that Attic helmets with browbands, which are often depicted on Roman propaganda monuments, are not the sculptors’ invention, but helmets really common in the Roman imperial army, imitating the models of the earlier period.
Medieval Georgian Poliorcetica
Authors: TSURTSUMIA Mamuka
Published: September 2022

In the medieval art of war siege constituted one of the principal forms of fight. Several basic techniques were used in taking a stronghold, such as assaulting the walls of the fortress, breaching the wall, digging a subterranean tunnel under the wall and enfeeblement of the garrison by lengthy siege. Bearing in mind various data, in the Middle Ages Georgians used the following technical means to capture fortresses: assault ladders, battering rams and other engines for breaching walls, ballistas, stone throwing engines and subterranean tunnels. In the article light is shed on the siege capabilities of the Georgian army of the period. Extensively discussed are the Georgian army’s stone throwing artillery, various types of stone hurling engines and the time of their spread in Georgia. Various techniques of capturing fortresses, applied by the Georgians are described. These include mounting the walls with ladder or various improvised means. The hazardous technique of directly assaulting the fortress without preliminary preparation or bringing up heavy siege engines is shown. The capturing of fortresses by means of underground tunnels isdiscussed separately. By the available evidence it is not apparent that Georgians made use of all the siege techniques known in the medieval world; however, it can be said that they were familiar with and used successfully the basic methods of siege warfare.
México-Tenochtitlan: la ciudad que surgió del agua y tocó el Sol
Authors: Bravo-Almazán Verónica
Published: September 2022

La arquitectura es parte sustancial de toda sociedad; se logra a través de un proceso productivo que permite la gestación conceptual: proyectar, organizar y, finalmente, materializar, en nuestro caso, la ciudad de México-Tenochtitlan. De su seno ideológico surgió el fenómeno urbano-arquitectónico que tanto ha fascinado, no sólo por el breve periodo en que emergió —menos de doscientos años—, sino también por su trazo preciso, organización urbana e innegable majestuosidad.

 Pero no surgió de la nada, dada la carencia de espacio constructivo y materiales, los cuales debieron traerse de otros lugares. Fue un logro de ingeniería generar espacio urbano y productivo en un medio acuoso; guarda en sus restos valiosos secretos de audacias constructivas que aún están descubriéndose. El estudio de estos vestigios es parte fundamental del patrimonio cultural e histórico del país y expresión de la composición pluricultural de la Nación Mexicana.

El culto del Estado mexica y el paisaje ritual de la Cuenca: mito, naturaleza y sociedad
Authors: Broda Prucha Johanna
Published: September 2022

Al estudio detallado del culto estatal mexica, basado en las descripciones de los cronistas españoles del siglo XVI, se aplica un enfoque interdisciplinario que combina la etnohistoria con la arqueología, la geografía y la arqueoastronomía. Hoy en día, aún subsisten vestigios arqueológicos en los cerros que rodean la Cuenca donde los sacerdotes del culto estatal mexica ejecutaban ritos y sacrificios en determinadas fechas de su calendario. La ubicación de estos lugares permite interpretar la visión simbólica del espacio y el diseño ritual que el Estado mexica imprimió a la geografía de la Cuenca. Esta visión reflejaba la complejidad del universo cultural mexica donde se combinaban sus observaciones acerca de la naturaleza, la geografía, la astronomía, el clima y los ciclos agrícolas en una cosmovisión multi-escalar basada en un íntimo conocimiento de la observación de los ciclos naturales. Además, se vislumbra en ella una conciencia histórica particular acerca del papel del Estado mexica. De esta manera, estos lugares de culto y su ubicación estratégica en el paisaje de la Cuenca expresaban también relaciones de dominio político porque al conquistar otras entidades políticas de la Cuenca, los mexicas se apropiaron de los santuarios de sus enemigos imprimiendo su propio sello a estos lugares sagrados. Así, el culto estatal mexica reflejaba relaciones de dominio plasmados a través de la expresión ritual en la misma geografía de la Cuenca, sus lagos y cerros ancestrales.

Introduction: Early in the pandemic, older people were identified as one of the most vulnerable population. More than 80% of deaths occur in adults over the age of 65. Several conditions have been clearly established to protect the elderly, such as banning visits to nursing homes. Therefore, it is important to fully understand how this pandemic has affected the elderly. This study covers the negative effects on the physical and mental health of the elderly during COVID-19 pandemic.
Methodology: A systematic review of the literature to identify COVID-19 papers with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) using PubMed, Google Scholar, Science Direct, BioMed Central (BMC) and Frontier in 2020 and 2021. Included studies are those that investigate the psychological and physical impact on elderly (>=60 years old) resulting from the impact of the COVID-19 pandemic. Unrelated, duplicated, unavailable full texts/abstract-only papers, and studies that analyzed mental and behavioral disorders due to the use of alcohol and other drugs are excluded.
Results: A total of 12 studies are included out of 352. Impact of COVID-19 on physical health to elderly were weight loss, lesser time of exercise, decreased social activities, increased respiratory and heart diseases, and increased mortality. On the other hand, identified impact on mental health were higher depression, anxiety, fear of acquiring COVID due to irresponsible younger generations, discrimination and isolation, increased levels of loneliness, and generalized anxiety.
Conclusion: The findings summarized in this review suggest that older adults experienced negative consequences for the ongoing pandemic, both physically and mentally. This information will be useful to responsible institutions when acting and making decisions for elderly regarding health care access and public health measures.

Objective: To establish normative values and a reference equation for the number of steps climbed during the six-minute step test (6MST) in healthy adults, and to assess the reliability of the test and of the equation. Methods: This was a multicenter cross-sectional study involving 468 healthy volunteers (age range: 18-79 years) recruited from the general community in six research laboratories across different regions of Brazil, which is a country with continental dimensions. The 6MST was performed twice (30-min interval), and clinical, demographic, and functional variables were evaluated. An independent sample of 24 volunteers was evaluated to test the reference equation a posteriori. Results: The number of steps had excellent test-retest reliability (intraclass correlation coefficient = 0.96 [95%CI: 0.95-0.97]), and the mean number of steps was 175 ± 45, the number being 14% greater in males than in females. The best performance on the test was correlated with age (r = -0.60), sex (r = 0.28), weight (r = 0.13), height (r = 0.41), BMI (r = -0.22), waist circumference (r = -0.22), thigh circumference (r = 0.15), FVC (r = 0.54), and physical activity level (r = 0.17; p < 0.05 for all). In the regression analysis, age, sex, height, and weight explained 42% of the variability of the 6MST. Normative values were established for the 6MST according to age and sex. There was no difference between the 6MST values from the independent sample and its predicted values (157 ± 29 steps vs. 161 ± 25 steps; p = 0.47; 97% of predicted values). Conclusions: The normative values and the reference equation for the 6MST in this study seem adequate to accurately predict the physical functional performance in adults in Brazil.

Distracted users appear to have difficulties correctly distinguishing between legitimate and malicious emails or search engine results. Additionally, mobile phone users appear to have a more challenging time identifying malicious content due to the smaller screen size and the limited security features in mobile phone applications. Thus, the goal of this research study was to conduct a pilot test and validate a set of field experiments based on Subject Matter Experts (SMEs) feedback to assess users’ judgment when exposed to two types of simulated social engineering attacks: phishing and Potentially Malicious Search Engine Results (PMSER), based on the interaction of the environment (distracting vs. non-distracting) and type of device used (mobile vs. computer). This paper provides the results from the pilot test we conducted using recruited volunteers consisting of 10 participants out of 20 volunteers invited. Due to COVID-19 restrictions, all interactions in this pilot testing were conducted remotely. These restrictions somewhat limited our ability to control the testing environment to ensure a completely non-distractive environment during these parts of the study; however, a significant attempt was made to ensure such a non-distractive environment was genuinely adhered to during that part of the study. Our initial pilot testing results indicate that the findings were counterintuitive for the Phishing Intelligence Quotient (IQ) tests. In contrast, results of the PMSER were intuitive with improved detection on a computer compared to mobile. We conclude with a discussion on the study limitations and further research.
Immunologically Neutral Dental Implants Ceramic (Zirconia) Implants

Since their introduction in the 1960s, titanium implants have dominated the field of dental implants. As a result, titanium implant systems are largely the foundation for the goods and solutions, scientific and clinical research, as well as the development and effectiveness of this treatment.The subject of when and why to substitute titanium implants with ceramics is evident for practitioners thinking about adding ceramic implants to their portfolios. Of course, every situation and patient are different, but there are a few things to take into account if ceramic and Titanium implants are an option based on the signs.The patient's resistance to having metallic medical devices inside their body, which might manifest as mucosal recession and the visibility of gray Titanium is one of the problems with titanium implants. The emotional feel of a more 'natural' alternative may be of preference.From a clinical perspective, recent developments in zirconia solutions now mean that the restorative flexibility of a two-piece, cemented, and/or screw-retained options are available, along with proven osseointegration and soft tissue adhesion, [1] generally lower plaque accumulation, [2] and less bacterial adhesion than titanium implants [3]. Titanium implants are narrower at the implant-abutment transition; however, ceramic implants should be wider, and which is what SDS has done since the wide tulip stabilizes the gingiva allowing it to attach. To preserve soft tissue and pink esthetics, Ceramic implants should be placed tissue-level. This will also prevent the disturbance of the valuable bond between implant and the tissue.In various range of cases, Ceramic implants are used as the substitute of the titanium implants as they are given esthetic white appearance and are 100% metal-free.
Clinical Approach to Coronectomy in Horizontally Impacted Mandibular Wisdom Teeth
Authors: Wiedemann Thomas G
Published: September 2022

Objective: This study is focused on the identification of comprehensible radiographical and clinical features for the risk assessment of coronectomies in horizontally impacted mandibular third molars which require surgical treatment. A classification, based on a literature review and well-defined risk assessment algorithm, has been developed to streamline the decision-making process.

Methods: A PubMed, OVID Medline and Google Scholar search for articles related to keywords such as “Coronectomy, Horizontal Impacted Third Molar, Coronectomy vs Extraction” has been performed.

Results: Only horizontally impacted mandibular 3rd molars which required surgical intervention were included. The relationship of the apical portion of the roots with the IAN, evaluated on the CBCT, was used to classify the tooth as low, medium or high risk for extraction. If a tooth was classified as medium or high risk for total removal, it was further assessed and classified for coronectomy. According to a literature review and to our clinical judgement, 4 indicators can beidentified as relevant in the individual risk assessment related to coronectomy. Based on a cumulative point score, the indication for a coronectomy has been appraised as ‘low risk', ‘moderate risk' or 'high risk’.

Conclusion: Horizontal impactions of lower third molars are not necessarily to be considered a contraindication for coronectomy. Our classification offers a guideline in the decision-making process on whether a coronectomy represents a viable treatment option for mandibular horizontally impacted third molars.
