Maintenance of sterility in SMS packaging in dental environments: concern with biosafety

Healthcare services must be guided by biosafety practices and microbial control. This control is highly influenced by humidity, which directly impacts the maintenance of sterility of the materials used in the appointments. High concentration of moisture, in the form of aerosol, splashes and spills, is caused during dental care. During the COVID-19 times the contamination by aerosol and droplets worries greatly. Considering that it could cause harm to the sterility of an autoclaved material, especially in dental environments, the objective was to evaluate the behavior of SMS sterilization packages (Spunbonded / Meltblown / Spunbonded) against microbial penetration in an aqueous vehicle. SMS of three brands were challenged, equally divided into two groups: virgin and processed (subjected to a single autoclaving cycle). Each specimen was aseptically deposited on Macconkey agar. Subsequently, 5 µL of Escherichia coliATCC 25922 saline solution [108CFU mL-1] was deposited in center of the SMS specimen and the dish incubated at36°C/ 48h. Reading was performed by the presence or absence of bacterial growth typical of the species under the SMS, observed on the back of Petri dish. The lowest penetration rate observed was 60% for one of the brands in the virgin condition, and 75% for two brands in the processed condition. Statistical analysis showed an association between bacterial penetration and the evaluated group, this association being valid only in the virgin condition. The different SMS behave similarly in terms of resistance to bacterial penetration after being processed. The data show that moisture can assist in bacterial transport through sterilized SMS. Therefore, SMS packages are not able to prevent bacterial penetration, and possibly other microorganisms, when in aqueous vehicles, offering a potential risk of breaking the aseptic chain. Thus, care must be taken in routines for handling and storage sterile packaging.

Tratamento da mordida aberta anterior: revisão de literatura / Treatment of previous open bite: literary review

Objetivo: realizar uma revisão de literatura sobre os tipos de tratamento empregados na correção da mordida aberta anterior. Materiais e métodos: foi realizada uma busca nas bases de dados PubMed, SciELO e Google Acadêmico. Os termos inseridos na pesquisa foram: Mordida Aberta; Ortodontia Corretiva; Ortodontia; Ortodontia Interceptora; Open Bite; Orthodontics, Corrective; Orthodontics; Orthodontics, Interceptive. Revisão da Literatura: a mordida aberta anterior (MAA) é uma má oclusão dentária que pode promover alteração do perfil e da fisionomia do indivíduo, dificultando também a apreensão e o corte dos alimentos. A MAA é uma das más oclusões de maior comprometimento estético-funcional, podendo ser dentária ou esquelética. A etiologia da mordida aberta anterior é multifatorial, sendo que as principais causas são hereditariedade e causas ambientais. Esses fatores interferem no crescimento e desenvolvimento normais das estruturas faciais, modificando não somente a morfologia, mas, também, a função do sistema estomatognático. Considerações finais: conclui-se que o diagnóstico precoce e a remoção do fator etiológico são fundamentais para a evolução adequada do tratamento ortodôntico.(AU)

Objective: to perform a literature review on the types of treatment used in anterior open bite correction. Materials and methods: a search was performed in the PubMed, SciELO, and Google Scholar databases. The terms entered in the search were Mordida Aberta; Ortodontia Corretiva; Ortodontia; Ortodontia Interceptora; Open Bite; Orthodontics, Corrective; Orthodontics; Orthodontics, Interceptive. Literature Review: anterior open bite (AOB) is a dental malocclusion that may change the profile and physiognomy of individuals, making it difficult to grasp and cut food. The AOB is one of the malocclusions with the most aesthetic and functional impairments, and it may be dental or skeletal. The etiology of anterior open bite is multifactorial and the main causes are heredity and environmental causes. These factors interfere with the normal growth and development of facial structures, modifying not only the morphology but also the function of the stomatognathic system. Final considerations: it is concluded that the early diagnosis and removal of the etiological factor are essential for the proper evolution of the orthodontic treatment.(AU)

Tratamiento de la hiperplasia gingival en una escuela odontológica de Brasil: conceptos generales, diagnóstico y tratamiento / Treatment of gingival hyperplasia in a dental school of Brazil: general concept, diagnosis and treatment

La hiperplasia gingival es una condición patológica benigna en la que aumenta de volumen de tejido gingival de forma lenta y gradual, causando importantes molestias estéticas y funcionales en los pacientes. Se clasifica como idiopática, inflamatoria, hereditaria y asociada a drogas, según su etiología, donde cada una tiene sus peculiaridades que deben ser bien comprendidas por el cirujano-dentista, a fin de lograr el tratamiento adecuado para cada caso. Este artículo revisa la literatura reciente sobre la hiperplasia gingival, abordando su etiología y tratamiento, presentando un caso clínico de fibromatosis gingival hereditaria y su tratamiento quirúrgico.

The gingival hyperplasia is a condition in which increase in volume in benign, slow and gradual development of the gingival tissue, causing significant discomfort and aesthetic function in patients. It is classified as idiopathic, inflammatory, and hereditary drug, according to its etiology, and that each variant has its peculiarities that must be well understood by the Clinical-Dentist, in order to achieve the appropriate treatment for each case. This paper reviews the recent literature on gingival hyperplasia, addressing its etiology and treatment given, and clinical case report of hereditary gingival fibromatosis in the surgical therapy was performed successfully.
