Avaliação de protocolos de clareamento dentário modificados por fontes luminosas / Evaluation of dental bleaching protocols modified by light sources / Evaluación de protocolos de blanqueamiento dental modificados por fuentes de luz

Introdução:Oclareamento dental é o procedimento estético mais realizado nos consultórios odontológicos. O uso de fontes luminosas tem sido recomendado para acelerar a ação do gel clareador, entretanto evidências científicas são controversas no que se diz respeito a essas fontes.Objetivo:Avaliar protocolos de clareamento dentário modificados por fontes luminosas, objetivando verificar, qual a influência dessas fontes no procedimento de clareamento dentário.Metodologia:Sendo essa, uma pesquisa que utilizou material biológico, a mesma foi submetida e aprovada pelo Comitê de Ética em Pesquisa da UEPB. Realizou-se a obtenção de dentes(n = 20)por meio de parceria com o Banco de Dentes Humanos do curso de Odontologia da UEPB Campus VIII. Posteriormente realizou-se identificação dos dentes, em seguida registro inicial da cor do dente(escala VITA), o preparo dos blocos dentários e seleção dos grupos. Os dentes foram submetidos a dois protocolos de clareamentos distintos, com luz halógena e com LED, com ou sem troca do gel. Por fim, realizada a análise estatística. Resultados:A modificação do protocolo, seja quanto o tempo de aplicação do agente clareador, seja quanto à fonte de luz utilizada, alcança resultados satisfatórios. Houve diferença estatisticamente significativa entre os gruposda luz halógena (p = 0.041)Conclusões:Tendo em vista os resultados e a discussão encontrados na pesquisa, podemos verificar que as evidências científicas nos levam a observar que não há bases suficientes que comprovem a eficácia e benefícios a curto prazo da modificação dos protocolos de clareamento dental pelas fontes luminosas (AU).

Introduction:Tooth whitening is the most common cosmetic procedure performed in dental offices. The use of light sources has been recommended to accelerate the action of the whitening gel;however scientific evidence is controversial regardingthese sources.Objective:Evaluate tooth whitening protocols modified by light sources, aiming to verify, what is the influence of these sources in the tooth whitening procedure. Methodology:This being a research that used biological material, it was submitted and approved by theResearch Ethics Committee of UEPB. Teeth (n = 20) were obtained through a partnership with the Human Teeth Bank of the Dentistry course at UEPB Campus VIII. Subsequently, teeth identification was performed, followed by initial registration of tooth color(VITA scale), preparation of dental blocks and selection of groups. The teeth were submitted to two different whitening protocols, with halogen light and with LED, with or without changing the gel. Finally, statistical analysis was performed. Results:Themodification of the protocol, both in terms of the application time of the bleaching agent and in terms of the light source used, achieves satisfactory results. There was statistically significant difference between groupswith halogen light (p = 0.041). Conclusions:In view of the results and the discussion found in the research, we can see that the scientific evidence leads us to observe that there are not enough bases to prove the effectiveness and short-term benefits of modifying the teeth whitening protocols by light sources (AU).

Views of patients and general dental practitioners on the organizational aspects of a general dental practice.

OBJECTIVE: To examine the views of patients and general dental practitioners (GDPs) on the organizational aspects of a general dental practice and to see whether their views differ. BACKGROUND: Health care has increasingly centred on the patient over the last two decades, and the patients' opinions have been taken more seriously. Although in other health-care sectors research on organizational aspects has been performed, research in dental care is lacking on this subject. DESIGN: We developed two questionnaires covering 41 organizational aspects of a general dental practice: one for GDPs and one for dental patients. The questionnaires were handed out in dental practices to 5000 patients and sent to 500 GDPs. RESULTS: We describe the results of the organizational aspects mentioned most by 25% of the dental patients. For most aspects, the views of the patients and GDPs differed significantly. However, both respondent groups mentioned the same category the most. CONCLUSIONS: The results of this study could be used on a policy level for the development of guidelines and on a practice level for individual GDPs to adjust practice management to the preferences of patients.

Salivary characteristics and dental caries: evidence from general dental practices.

BACKGROUND: Saliva is one of the intraoral host factors that influence caries development. The authors conducted a study to investigate whether salivary characteristics are associated with recent dental caries experience. METHODS: Dentist-investigators and dental staff members collected data pertaining to a two-year cumulative incidence of dental caries (previous 24 months) and salivary characteristics during baseline assessment in an ongoing longitudinal study. The systematic random sample consisted of patients (n = 1,763) visiting general dental practices (n = 63) within the Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry (PRECEDENT). The authors estimated adjusted rate ratios (RRs) by using generalized estimating equations log-linear regression to relate salivary characteristics to coronal carious lesions into dentin. RESULTS: Low resting pH (≤ 6.0) in the overall sample and low stimulated salivary flow rate (≤ 0.6 milliliter/minute) in older adults (≥ 65 years old) were associated with increased dental caries (RR, 1.6; 95 percent confidence interval [CI], 1.1-2.2; RR, 2.4; 95 percent CI, 1.5-3.8, respectively). Low buffering capacity was associated with decreased dental caries in children and adolescents (RR, 0.3; 95 percent CI, 0.1-1.0; RR, 0.2; 95 percent CI, 0.1-0.7, respectively). A thick, sticky or frothy salivary consistency also was associated with decreased dental caries in adults (RR, 0.6; 95 percent CI, 0.4-1.0). Associations between other salivary characteristics and dental caries for the overall sample and within each age group were not statistically significant. CONCLUSIONS: Salivary characteristics were associated weakly with previous dental caries experience, but the authors did not find consistent trends among the three age groups. Different salivary characteristics were associated with an increased caries experience in older adults and a lowered caries experience in children and adolescents and adults. Practical Implications. Further investigations are needed in this population setting to understand the study's conflicting results. The study findings cannot support the use of salivary tests to determine caries risk in actual clinical settings.

Avaliação dos conhecimentos de ergonomia em acadêmicos do ciclo profissional em uma Faculdade de Odontologia do sistema público de educação superior em Pernambuco¹ / Evaluation of the ergonomics knowledge in undergraduate of the professional course in a Dentistry's Faculty of the higher education public system in Pernambuco

Objetivo: avaliar o nível de conhecimento, de aplicação e de cobrança da Ergonomia na prática clínica. Material e Métodos: estudo descritivo, observacional de corte transversal realizado com 174 alunos, de ambos os gêneros, regularmente matriculados entre o 4º e o 9º período do currículo antigo de uma Faculdade de Odontologia do sistema público de educação superior em Pernambuco, por meio de um questionário contendo 16 conhecimentos básicos de Ergonomia e 10 situações ergonômicas a serem exigidas pelas disciplinas clínicas. Resultados: a amostra foi predominantemente feminina (67,2%). Como o conceito mais apreendido pelos estudantes, tem-se: No conceito de ergonomia não podem faltar às palavras conforto, segurança e eficiência (92,0%), e o menos apreendido foi o seguinte: A maioria dos equipos da faculdade é conceito ISO/FDI 3/ (13,2%). Apenas um conhecimento se associou ao gênero, dois, à idade, e treze, ao período cursado. A melhor taxa de acertos foi do 9º período, e a pior, a do 7º. A situação ergonômica mais exigida pelas disciplinas se relacionou ao uso correto do EPI (50,7%), e a menos exigida, à ginástica laboral (2,7%). A disciplina com maior média de exigência dos conhecimentos de Ergonomia e de sua aplicação foi a Clínica Integrada II (2,40), e a de menor média, a Prótese Fixa II (1,55). Todas as situações ergonômicas se associaram ao período cursado. Conclusões: os conhecimentos de Ergonomia perdem-se ao longo do tempo, e essa perda se deve, em parte, à falta de exigência das disciplinas. A disciplina de Clínica Integrada II é quem mais exige esses conhecimentos e sua aplicação.

Objective: To investigate the level of ergonomics' knowledge and its application in clinical practice. Material and Methods: descriptive and observational study of a sectional cross realized with 174 students, of both genders enrolled between 4th and 9th semesters of the old curriculum of the Dentistry's Faculty of the higher education public system in Pernambuco by applying a survey containing 16 regards basic knowledge of Ergonomics and 10 ergonomic situations to be required by the clinical disciplines. Results: The sample was predominantly female (67.2%). The concept was perceived by the most in the Concept of ergonomics can not miss words to comfort, safety and efficiency (92.0%) and was apprehended less Most equipos of faculty concept is ISO / FDI 3 / (13.2%). Only a knowledge is linked to gender, to age two, and thirteen of the period attended. The best accuracy rate was the 9th time and the worst of the 7. The most ergonomic situation was related disciplines required by the correct use of PPE (50.7%) and less required was related to gymnastics (2.7%). The discipline with the highest average requirement of ergonomics' knowledge and its application was the Integrated Clinic II (2.40) and lowest average was the Fixed Prosthodontics II (1.55). All cases were associated with ergonomic period attended. Conclusions: The knowledge of ergonomics are lost over time and this loss is partly due to lack of demand disciplines. Discipline of Integrated Clinic II is looking more demands that knowledge and its application.
