  • Congenital atresia of the submandibular gland duct: report of two clinical cases with spontaneous regression and literature review
    por Lara Oliveira Freitas el mayo 12, 2022 a las 5:00 am

    Background: Congenital atresia of the submandibular gland duct is a rare condition, originated during the embryogenic process, characterized by swelling in the region of the oral floor. A few cases of congenital atresia of the submandibular gland duct have appeared in the literature and only one reports no surgical intervention to date. Case series: In the present study reports two cases of babies with clinical findings demonstrating swelling well-defined in the region of the oral floor, slightly translucent bluish color, painless to palpation, without finding stones or salivary drainage and apparently with no perforation of the submandibular gland duct. Both patients were kept under observation, later presenting spontaneous regression. Conclusion: This study highlights the importance of conducting a thorough clinical examination in addition to showing that the use of complementary exams may not be essential.

  • Identification of candida in mouth cavity of patients with diabetes and hiv / aids
    por Helen Jose Mosquera Cardenas el marzo 11, 2022 a las 5:00 am

    Introduction: Candida is an invasive microorganism that becomes pathogenic when there is an alteration in the balance of the flora or in the weakening of the host. It can generate important infections in healthy and immunodeficient people. Objective: to characterize Candida in two different pathological conditions such as diabetes, acquired immunodeficiency virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS). Method: A systematic review was carried out according to the protocol based on the PRISMA declaration checklist using the following databases: Clinical Key®, Medline®, PubMed®, Scielo® and indexed journals. Results: The disease in the which was the highest prevalence of Candida infections was HIV / AIDS, the type of Candida that was found was C. albicans, the type of candidiasis that occurred most frequently in individuals with HIV / AIDS was Pseudomembranous and Erythematous. Diabetes mellitus type II was the most common type of diabetes, the most common type of Candida was C. albicans, C. glabrata, C. tropicalis and C. krusey, the type of candidiasis that prevailed was erythematous. Conclusion: We can conclude that C. albicans is most prevalent among oral diseases in immunocompromised patients and with HIV / AIDS, due to the susceptibility of the organism to certain infections.

  • Prevalência de infecções hospitalares e assistência odontológica: um estudo transversal.
    por Lara Maria Moreira de Faria el marzo 9, 2022 a las 5:00 am

    Aim: To make a comparison between the prevalence of hospital infections over a period of 13 months between two groups: patients hospitalized without dental care and with dental care. Methods: This was a descriptive cross-sectional study, through data regarding the rates of hospital infections obtained in two groups: with and without dental care, considering more specifically the sectors: Intensive care unit (ICU) and neruological clinic. Patients over 16 years-old, of both genders and who were diagnosed with hospital infection after 48 hours of hospitalization or 48 hours after discharge, were included in the sample. Results: Between March 2016 and March 2017, a prevalence of hospital infection was observed of 3. 14% in patients without dental care and from March 2017 to March 2018, the prevalence was 2. 85% in patients who had dental care. Conclusion: The ICU was the sector with the highest occurrence of infections. Dental care was not associated with the occurrence of infections.

  • Types of retention for implant-supported fixed prosthesis: a narrative literature review
    por Clara Almeida-Mares el marzo 5, 2022 a las 5:00 am

    Background: The development of implant dentistry, along with implant-supported prostheses, made it possible to carry out functional and aesthetic rehabilitation treatments for patients, promoting comfort and durability in the results. For the achievement of the rehabilitation treatment, the choice of the retentive system of the prosthesis that best suits the patient's expectations, together with their clinical and radiographic conditions is essential. Objective: Perform a literature review addressing the main retention systems for fixed prostheses on implants, especially screwed and cemented, contextualizing them with new materials, components and techniques, guiding the decision-making of dental surgeons for their clinical planning. Materials and methods: A bibliographic search was performed on MEDLINE, Embase, Cochrane Library and SciElo platforms, filtering articles in Portuguese or English, with no date restriction until June 2, 2021. Conclusion: The choice of the retention system to be used involves several factors. A gold standard retention technique has not yet been established, due to the advantages and disadvantages of each. The choice of retention method must be made in conjunction with the patient and more clinical studies with longer follow-up are necessary to obtain more information.

  • 3D Printing in Dental Science
    por Edison Andrés Cruz Olivo el marzo 3, 2022 a las 5:00 am

    3D printing is a technology that describes a manufacturing process previously planned and designed in a computer to create an object 1,2. This technology was introduced in dentistry by Chuck Hull since 1986 and allowed the automation and thus improved dental workflow 2. Technologies used in 3D printing involves: Stereolithography (SLA), bioprinting, fused deposition modeling (FDM), selective laser sintering (SLS), and PolyJet printing. We can choose one of them depending on the clinical use and material, need of accuracy among others.   To 3D printing you need to use a scanner with an integrated software in order to capture the 3D images of the object being scanned. Those 3D images are stored in Standard Tessellation Language (STL) file 3. But what “Tessellation” means? Tessellation is the covering process of a surface, using one or more geometric shapes, with no overlaps and no gaps. It means that the object scanned is copied in detail with high reliability and then can be printed.   Before printing, the software cuts the STL file into multiple horizontal layers and creates the G-code for the machine command for the printer. Thus, the resolution of the printer is determined by its layer thickness (z-axis) which represents the vertical accuracy of 3D printer 1. There are two approaches used to fabricate 3D objects: subtractive approach (milling); additive approach (layered manufacturing) 4 . The first, normally use a small model or block to machining it and is indicated to fabricate ceramic crowns in dentistry. The last, can produce complex structures and thus is suitable for reproduce the anatomy of different structures of oral cavity 4.
