Protokoli u klasifikaciji krezubosti

This paper shall discuss the importance of protocol application in modern dentistry. Literature data that include recommendations and consensuses in dental practice point out to their presence in available literature, printed papers, reviewed journals and supplements in the form of expert group conclusions. It should be noted that the protocols most commonly rely on valid postulates of different branches of medicine, supported by specific conditions of the environment in which they are implemented. Additionally, in our settings, applicable dentistry protocols are the result of requirements that institutions and practices should fulfill according to renewable accreditation, as well as following recommendations given in the good clinical practice guidelines with different binding obligations levels. Certain protocols offer therapeutic modalities categorized into classes intended to help users to select appropriate treatments. The second part of this paper shall address one such protocol which classifies partially edentulous patients. The emphasis is on the partial edentulism classification recommended by The American College of Prosthodontists (ACP), which relies on four diagnostic criteria essential for therapeutic decision. Edentulous areas location and extent, abutment teeth health, occlusion model, and residual ridge characteristics represent the parameters which have defined the four classes of partial edentulism of different complexity. In this way, comprehensive approach to the clinical status of the patients has, for the first time been offered to the dental practitioners assuring, among others, higher uniformity of professional attitudes in selection of therapeutic modalities.U radu se diskutuje o značaju primene protokola u savremenoj stomatologiji. Literaturni podaci koji obuhvataju preporuke i konsenzuse u stomatološkoj praksi govore o njihovoj prisutnosti u dostupnim knjigama, štampanim radovima u recenziranim časopisima, i dodacima časopisa kao zaključci ekspertskih grupa. Treba primetiti da su protokoli najčešće oslonjeni na validne postulate različitih medicinskih grana, pomognuti specifičnim uslovima sredine u koju se implementiraju. Dodatno, u našim uslovima, protokoli u stomatologiji su rezultat zahteva koje institucije i prakse moraju da ispunjavaju shodno obnovljivoj akreditaciji, kao i poštovanja preporuka koje su date u vodičima dobre kliničke prakse različitog nivoa obaveznosti. Pojedini protokoli nude terapijske modalitete koji se kategorizuju u klase, pomažući korisnicima u izboru pravog tretmana. O jednom od takvih protokola koji klasifikuje krezube pacijente govori drugi deo rada. Akcenat je na primeni klasifikacije krezubosti koju je preporučio Američki koledž protetičara, a koja se oslanja na četiri dijagnostička kriterijuma, bitna za terapijsku odluku. Lokalizacija i veličina bezubih polja, stanje zdravlja zuba nosača, model okluzije i karakteristike rezidualnog grebena su parametri koji su definisali četiri klase krezubosti različite složenosti. Tako je, prvi put, stomatološkoj praksi ponuđen ozbiljan, sveobuhvatni pristup kliničkom statusu bolesnika, koji obezbeđuje, između ostalog, i uniformnije stručne stavove u izboru terapijskih modaliteta

Etika i marketing u estetskoj stomatologiji

Contemporary dentistry is, first of all, characterized by diverse accelerated development, owing to improvements of information and other technologies, as well as the development of dental materials (shape-memory biomaterials, nanomaterials, biomaterials for application in tissue engineering, etc.). Expert doctrinaire attitudes move from the direction of operative interventions, whereby disease and acute symptoms are primarily treated, towards the strengthening of oral health by minimally invasive procedures. A particular place in patients’ total rehabilitation belongs to numerous esthetic procedures which, to a large extent, make up a wants-based service, led by the patients’ needs and affinities. This paper deals with differences between cosmetic and esthetic dentistry. The complexity of esthetic dentistry, which favors therapy with the change of function parameters in care for the patient, is emphasized. On the other hand, more attention is paid to the need to know and respect ethical and marketing principles that follow any activity of dentists, starting from the first contact with the patient, the selection of certified materials, to the implementation of the appropriate treatment plan. Well-directed communication and comprehensive awareness of the patient, the use of the visual analog scale, consideration of realistic resources in therapy, and the acceptance of de Bono model of adopted parallel thinking are determinants which help dentists define a problem adequately, find quality solutions, open alternative solutions, and reduce the potential risks in patients’ therapy.Današnju stomatologiju karakteriše ubrzani razvoj zahvaljujući unapređenju informacionih i drugih tehnologija, kao i razvoju dentalnih materijala (biomaterijali sa memorisanim oblikom, nanomaterijali, biomaterijali za primenu u tkivnom inženjeringu i dr.). Stručni doktrinarni stavovi kreću se iz pravca operativnih intervencija, kojima se primarno saniraju bolest i akutni simptomi, ka jačanju oralnog zdravlja malo invazivnim postupcima. Posebno mesto u sveukupnoj rehabilitaciji bolesnika pripada brojnim estetskim procedurama, koje u velikoj meri čine praksu vođenu potrebama i afi- nitetima bolesnika. U radu se diskutuje o razlikama u poimanju kozmetske i estetske stomatologije. Naglašena je složenost estetske stomatologije, koja daje prednost terapiji sa promenom funkcijskih parametara u zbrinjavanju bolesnika. S druge strane, akcenat se stavlja na potrebu poznavanja i poštovanja etičkih i marketinških načela koja prate svaku aktivnost lekara, počev od prvog kontakta sa bolesnikom, odabira sertifikovanog materijala do realizacije odgovarajućeg terapijskog plana. Dobro usmerena komunikacija i sveobuhvatna informisanost bolesnika, upotreba VAS skale, kao i sagledavanje realnih resursa u terapiji odrednice su koje pomažu stomatologu da definiše problem na pravi način, iznađe kvalitetna rešenja, otvori alternativne solucije i smanji moguće rizike u terapiji bolesnika

Nusproizvodi agro-industrije kao izvor održivih sastojaka za proizvodnju funkcionalne hrane i nutraceutika

The disposal of waste generated in the agri-food industry is one of the greatest challenges in achieving sustainable development. Although agri-food residues are a potential source of bioactive compounds with proven health benefits, they are largely unused and disposed of as organic waste. The recovery of bioactive compounds from agri-food waste to obtain products with high biological value, such as functional foods and nutraceuticals, is an idea that stems from the concept of bioeconomy and combines environmental issues with economically viable production. Some of the main agri-food wastes in Serbia that have the potential to be recycled into value-added products are apple, plum, grape, tomato, and beet pomace, and oilseed cakes. Bioactive compounds isolated from these wastes include polyphenols, fibers, essential fatty acids, minerals, various volatiles and pigments. This article focuses on the most common food wastes and the potential reuse of these undervalued material to produce value-added products such as functional foods, nutraceuticals or food additives.Odlaganje otpada koji nastaje u prehrambenoj industriji jedan je od najvećih izazova u postizanju održivog razvoja. Iako su nusproizvodi koji nastaju u prehrambenoj industriji potencijalni izvor bioaktivnih jedinjenja sa dokazanim pozitivnim zdravstvenim efektima, oni se uglavnom odlažu kao organski otpad. Iskorišćenje bioaktivnih jedinjenja iz ovih nusproizvoda u cilju dobijanja proizvoda sa dodatom nutritivnom i biološkom vrednošću, kao što su funkcionalna hrana i nutraceutici, ideja je koja proizilazi iz koncepta bioekonomije i kombinuje ekološki aspekt sa ekonomski održivom proizvodnjom. Neki od glavnih nusproizvoda koji se generišu u Srbiji sa potencijalom da se iskoriste u proizvodnji proizvoda sa dodatom vrednošću su trop jabuke, trop šljive, komina grožđa, trop paradajza, uljane pogače i dr. Bioaktivna jedinjenja izolovana iz ovih otpada uključuju polifenole, peptide, vlakna, esencijalne masne kiseline, minerale, različite isparljive materije i pigmente. Ovaj članak se fokusira na najčešće otpade prehrambene industrije i potencijalnu ponovnu upotrebu ovog još uvek neiskorišćenog otpadnog materijala za proizvodnju proizvoda sa dodatom vrednošću kao što su funkcionalna hrana, nutraceutici ili aditivi

Corrosion coupon testing of commercial inhibitor in simulated cooling water

In maintaining cooling systems, one of the biggest challenges is to control the corrosion process. Various corrosion inhibitors are often used for this purpose. Which type of corrosion inhibitor will be chosen depends on the material from which the plant has made. The main causes of corrosion in these systems are: pH, dissolved gas, ammonia, temperature and microbiology. In this paper it was studied the efficiency of two multicomponent commercial corrosion inhibitors based on phosphates and one of which containing zinc chloride. For the purposes of research, the pilot plant of open recirculation cooling system is constructed and made of stainless steel (EN 1.4301) and copper (EN 13601). Experiments were performed in a simulated cooling water witch recirculated for 3.5h. For the purpose of accelerating corrosion processes, it was added a corrosion activator (5% NaCl). It was monitored the corrosion rate of the mentioned materials in the cooling water with the corrosion activator, with and without inhibitor. Corrosion rate is determined by using corrosion coupons according standard ASTM D2688 and by analyzing physical-chemical parameters of cooling water. The results showed it was achieved higher protection efficiency for copper and stainless steel by using an inhibitor containing zinc chloride in addition to phosphate

Electrooxidation of polar benzotriazole - The impact of supporting electrolyte

Polar benzotriazoles are heterocyclic compounds widely used in industry, and as such are easily released into the environment. These compounds show harmful and toxic effects on plants and some aquatic organisms, biodegrade quite slowly, and some, depending on the structure, have the ability to bioaccumulate. They can only be partially removed by conventional wastewater treatment, and are therefore found in a variety of waters, as well as solid waste. In this paper, synthetic wastewater containing polar benzotriazole was treated by an electrooxidation process. The efficiency of the treatment was tested depending on various parameters, such as: anode material (mixed metal oxide - MMO and boron-doped diamond - BDD), applied current density (10 and 20 mA/cm2), type of supporting electrolyte (NaCl, Na2CO3, Na2SO4, H2SO4) and treatment time (0.5 - 2.5 h). Obtained results showed the treatment was more effective at higher current density and by using BDD anode. Also, the efficiency of the treatment increases with the prolongation of the electrolysis time. After 2.5 h of treatment, 97.9% of benzotriazole was removed, in the presence of sulfuric acid as supporting electrolyte
