AIM OF THE STUDY:The present research attempts to assess the occurred linear changes of additional silicone impressions after utilizing different disinfection materials. MATERIALS AND METHODS:In the present study, a set of twenty-four impressions of a standard reference model were made using Polyvinyl siloxane impression material. The samples were split to form three groups (𝑤𝑤ℎ𝑒𝑒𝑒𝑒𝑒𝑒 𝑛𝑛 = 8) according to disinfection material used; sodium hypochlorite (SH), ozonated water (OW), and a control group (C). Group SH and Group OW were immersed at room temperature for up to 10 minutes. The prepared impressions were investigated before and after the disinfection procedure utilizing Dental Cone beam Computed Tomography (CBCT). Linear measurements were accurately determined between four reference points through the scanned digital models. After disinfection, the dimensional changes were calculated, and statistical analysis was conducted where the p-value was set as 𝑝𝑝 < 0.05. RESULTS: Each linear measurement for the three groups was analyzed using paired measurements before and after the disinfection process. The computed values prior to and following disinfection showed a significant difference when comparing the study groups as (𝑝𝑝 < 0.05). Moreover, the observed significant differences among the study groups were confirmed by applying one-way ANOVA analysis to assess the variance for each measurement. CONCLUSIONS: The dimensional accuracy of polyvinyl siloxane impression material performed well after using different disinfectant. Impressions were totally immersed in ozonated water showed better stability than impressions were totally immersed in NaOCl.

“…Aparte en la desinfección química se pude utilizar el método de aspersión o el de inmersión para desinfectar una impresión (22-2-3). Otros métodos utilizados son la radiación ultravioleta, microondas (15)(16)(17)(18)(19)(20)(21)(22)(23), desinfección activada por sonicador que es un homogeneizador ultrasónico para activar la solución desinfectante a 20 kHz (24).…”

“…Entre los materiales de impresión utilizados en odontología tenemos a los hidrocoloides reversibles e irreversibles y los elastómeros como las siliconas o los poliésteres (3-16-23) , algunas siliconas presentan propiedades hidrofílicas por lo que son susceptible a cambios dimensionales al ser sumergidos en soluciones (16)(17)(18)(19)(20)(21)(22)(23).…”

“…Los elastómeros son muy utilizados por la capacidad de reproducir detalles finos a un nivel de 20 un o menos (23), entre las más utilizadas tenemos a la silicona de adición o vinilo polisiloxano y las siliconas de poliéter de vinilo (16). Las siliconas de adicción ofrecen mayor precisión de impresión por sus propiedades hidrofobicas, con una buena resistencia al desgarro y mayor estabilidad (23-7-8-24) .…”

En la Clínica odontológica el uso de impresiones dentales es un procedimiento común utilizado en las diferentes especialidades con el objetivo de tener un diagnóstico preciso del paciente en las diferentes áreas, así como la elaboración de elementos protésicos. Por lo cual una impresión para ser llevada al laboratorio o vaciada en yeso sigue un protocolo de desinfección el cual consiste en la aplicación de soluciones desinfectantes con el fin de reducir los microorganismos que quedan en la impresión por el contacto con la saliva o sangre, de esta forma se reduce la infección cruzada que usualmente es entre el odontólogo y el laboratorio o personal encargado del manejo de impresiones, este proceso retoma su importancia al enfrentarnos a la pandemia del COVID-19 , con esta revisión de literatura se busca conocer los métodos y los agentes de desinfección utilizados en odontología previo a la pandemia del COVID -19 y en el trascurso de esta .La OMS recomienda el uso del hipoclorito de sodio al 5% .

Objective:The risk of gallstones is increased in fatty liver, overweight, and metabolic syndrome. The hyperinsulinemiceuglycemic clamp method is considered the best method for insulin resistance (IR); but it is a time consuming and expensive procedure. As an alternative strategy, in this study, we would like to demonstrate the triglyceride-glucose (TyG) index as the predictor of the development of gallstone disease associated with metabolic disorders. Methods:The TyG was investigated in our study with 1484 patients between the ages of 18-75 who underwent follow-up and/ or cholecystectomy due to gallstones. The serum fasting blood glucose and triglyceride levels of the patients were measured in the biochemistry laboratory of our hospital. The bile ducts and gallstones of all patients were evaluated with the Philips Affiniti 50 (The Philips Affiniti 50 Ultrasound; Philips North America Corporation 3000 Minuteman Road M/S 109 Andover, MA 01810, USA) ultrasonography device used by radiologists in the radiology clinic of our hospital. The data obtained were evaluated in SPSS, and p<0.05 was considered significant.Results: Our study includes 1484 (980 female, 504 male) patients. The plasma glucose (124.6±24.5 mg/dL), triglyceride (198.3±36.8 mg/dL), insulin (16.5±5.6 uIU/mL), and Homeostasis Model Assessment of IR 4 level (8±1.2), were at statistically and significantly higher levels in the patients than in the control group (p=0.001). It was found that the basal TyG was associated with the primary endpoint incidence of gallstones at significant levels. The ÖZ Amaç: Yağlı karaciğer, obezite ve metabolik hastalıklarda safra kesesi taşı görülme riski artmıştır. Hiperinsülinemik-glisemik klemp yöntemi insülin direnci (IR) için "altın standart" bir yöntem olarak kabul edilmektedir, ancak zor ve maliyetlidir. Alternatif bir yöntem olarak daha hızlı ve daha düşük maliyetli biyokimyasal ölçüm olan trigliseride-glukoz (TyG) indeksi, metabolik bozukluklarla ilişkili olan safra kesesi taşı hastalığı tanısında yararlı olabilir. Bu çalışmanın amacı safra kesesi taşı tanısında TyG indeksinin etkinliğini değerlendirmektir.Yöntemler: Çalışmada, safra kesesi taşı ile takip ve/veya kolesistektomi yapılan 18-75 yaş aralığında olan 1484 olgularda TyG indeksi araştırıldı. Hastaların serum açlık kan glukoz ve trigliserid düzeyleri hastanemiz biyokimya laboratuvarında ölçüldü. Tüm hastaların safra yolları ve safra taşları hastanemiz radyoloji kliniğinde radyologlar tarafından kullanılan Philips Affiniti 50 (The Philips Affiniti 50 Ultrasound; Philips North America Corporation 3000 Minuteman Road M/S 109 Andover, MA 01810, USA) ultrasonografi cihazı ile değerlendirildi. Elde dilen veriler SPSS'de değerlendirildi, p<0,05 anlamlı kabul edildi.Bulgular: Araştırmaya toplam 1484 (980 kadın ve 504 erkek) hasta alındı. Çalışmamızdaki biyokimyasal parametrelerden açlık safra kesinde taş saptanan olgularda plazma glukoz 124,6±24,5 mg/dL, trigliserid 198,3±36,8 mg/dL, insülin 16,5±5,6 uIU/mL, IR'nin Homeostatik Modeli Değerlendirmesi 4,8±1,2 seviyesi ...
