RELAÇÃO ENTRE LIMITAÇÃO DE ABERTURA BUCAL, ALTERAÇÕES SALIVARES E ACÚMULO DE BIOFILME DENTAL EM PACIENTES COM CÂNCER DE CABEÇA E PESCOÇO SUBMETIDOS À RADIOTERAPIA E QUIMIOTERAPIA

Os principais tratamentos para as neoplasias de cabeça e pescoço incluem quimioterapia, radioterapia, cirurgia ou uma combinação destes (LIN et al., 2021). Porém, qualquer que seja o método escolhido, pode haver sequelas ou efeitos adversos ao sistema estomatognático do paciente, como limitações para abertura bucal (trismo) e alterações do fluxo salivar, que podem influenciar no acúmulo de biofilme dental

Relação entre fluxo saliva e acúmulo de biofilme dental em pacientes submetidos à radioterapia na região de cabeça e pescoço

A radioterapia é o tratamento mais utilizado no câncer de cabeça e pescoço, e consiste em radiações ionizantes, que atuam sobre o DNA das células malignas, levando à morte celular ou à perda de sua capacidade reprodutiva, alcançando um índice terapêutico favorável. Porém, altas doses de radiação em extensos campos levam a reações adversas ao organismo, principalmente na mucosa oral (CIUPA, 2014)

USO DA ARGININA NO TRATAMENTO DA HIPERSENSIBILIDADE DENTINÁRIA: UMA REVISÃO INTEGRATIVA.

Objetivo: revisar a literatura acerca da eficácia das intervenções baseadasno uso de arginina no tratamento da hipersensibilidade dentinária eidentificar a terapêutica mais apropriada para aplicação no âmbito daprática clínica odontológica. Materiais e Métodos: apoiando-se nametodologia PRISMA (Preferred Reporting Items for Systematic reviewsand Meta-Analyses), a pesquisa bibliográfica se deu a partir dosdescritores: Arginina, Hipersensibilidade Dentinária, Tratamento e seuscorrespondentes na língua inglesa Arginine, Dentinal Hypersensitivity,Treatment, nas bases de dados eletrônicas LILACS e PubMed/Medline eem artigos publicados entre 2012 e 2021. Resultados: a amostra foiconstituída de onze publicações e após a análise, observou-se que quatrométodos de uso da arginina para tratamento da hipersensibilidadedentinária foram preconizados, demonstrando diferentes índices deeficácia. Considerações finais: o uso de dentifrícios contendo carbonatode cálcio e arginina 8% revelou ser uma forma de intervenção eficaz, debaixo custo, de fácil uso e aplicação caseira, embora se verifique nosestudos analisados a escassez de estratégias capazes de mensurar oalívio da dor de forma menos subjetiva e mais precisa. Purpose: to review the literature on the efficacy of arginine-basedinterventions in the treatment of dentin hypersensitivity and to identify themost appropriate therapy for application in clinical dental practice. Materialsand methods: built on the PRISMA (Preferred Reporting Items forSystematic reviews and Meta-Analyses) metodology, the literature searchwas based on the descriptors: Arginine, Dentinal Hypersensitivity,Treatment in the electronic databases LILACS and PubMed/Medline, inarticles published between 2012 and 2021. Results: the sample consistedof eleven publications and after analysis, it was observed that four methodsof arginine use for dentinal hypersensitivity treatment were advocated,demonstrating different efficacy rates. Final considerations: the use oftoothpastes containing calcium carbonate and arginine 8% proved to be aneffective form of intervention of low cost, easy to use and home application,although it is verified in the analyzed studies the lack of strategies capableof measuring pain relief in a less subjective and more accurate wa

Waiting Time for Coronal Preparation and the Influence of Different Cements on Tensile Strength of Metal Posts

This study aimed to assess the effect of post-cementation waiting time for core preparation of cemented cast posts and cores had on retention in the root canal, using two different luting materials. Sixty extracted human canines were sectioned 16 mm from the root apex. After cast nickel-chromium metal posts and cores were fabricated and luted with zinc phosphate (ZP) cement or resin cement (RC), the specimens were divided into 3 groups (n = 10) according to the waiting time for core preparation: no preparation (control), 15 minutes, or 1 week after the core cementation. At the appropriate time, the specimens were subjected to a tensile load test (0.5 mm/min) until failure. Two-way ANOVA (time versus cement) and the Tukey tests (P < 0.05) showed significantly higher (P < 0.05) tensile strength values for the ZP cement groups than for the RC groups. Core preparation and post-cementation waiting time for core recontouring did not influence the retention strength. ZP was the best material for intraradicular metal post cementation

Development and Validation of an Educational Comic Book for Guidance on the Safe Use of Fluoride Toothpaste by Children

Objective: To describe the elaboration and content validation of a comic book for guidance on the safe use of fluoride toothpaste by children. Material and Methods: Study on the development of educational technology carried out in four phases: 1 – literature review and script; 2 – elaboration of the material (illustrations, layout and design), 3 – validation (Content Validity Index = CVI and Flesch Readability Index = FI), 4 – pilot test to legitimize the material with the target population. Thirty-one individuals participated in the validation, being 07 expert judges and 24 representatives of the lay population, responsible for the daily care of preschool and school-age children. Results: In the validation, CVI= 0.97 (97%), indicating high agreement of the judges\u27 answers; and FI = 92%, which corresponds to “very easy to understand” reading. In the pilot test carried out with the lay population, the 3 assessment blocks had CVI=1.0 (100%). Conclusion: The comic book proved to be valid regarding appearance and content and can be used for health education activities for adults on the use of fluoride toothpaste for oral hygiene in children

Salivary cortisol in top-level professional soccer players

We have tested the hypothesis that salivary cortisol increases after a competitive training match in top-level male professional soccer players divided in team A (n = 11) versus team B (n = 11). Saliva samples collected before and after the match were analyzed. Salivary cortisol concentrations were measured by enzyme-linked immunosorbent assay. The results from a two-way ANOVA with repeated measures showed no significant changes in salivary cortisol between either teams or time points (P > 0.05). Further investigation regarding competitive matches in a competition environment is warranted. In summary, the influence of intensive competitive training match alone appears to be minimal on salivary cortisol changes in top-level soccer adapted to this type of stress. From a practical application, the variability of the responses among the players leads us to suggest that there is a need to individually analyse the results with team sports

Monitoring stress tolerance and occurrences of upper respiratory illness in basketball players by means of psychometric tools and salivary biomarkers

The aim of the study was to evaluate the possible relationships between stress tolerance, training load, banal infections and salivary parameters during 4 weeks of regular training in fifteen basketball players. The Daily Analysis of Life Demands for Athletes` questionnaire (sources and symptoms of stress) and the Wisconsin Upper Respiratory Symptom Survey were used on a weekly basis. Salivary cortisol and salivary immunoglobulin A (SIgA) were collected at the beginning (before) and after the study, and measured by enzyme-linked immunosorbent assay (ELISA). Ratings of perceived exertion (training load) were also obtained. The results from ANOVA with repeated measures showed greater training loads, number of upper respiratory tract infection episodes and negative sensation to both symptoms and sources of stress, at week 2 (p < 0.05). Significant increases in cortisol levels and decreases in SIgA secretion rate were noted (before to after). Negative sensations to symptoms of stress at week 4 were inversely and significantly correlated with SIgA secretion rate. A positive and significant relationship between sources and symptoms of stress at week 4 and cortisol levels were verified. In summary, an approach incorporating in conjunction psychometric tools and salivary biomarkers could be an efficient means of monitoring reaction to stress in sport.
