Objective This study evaluated the influence of over‐the‐counter agents on the maintenance of color and microhardness of the enamel after home bleaching protocol. Materials and methods Specimens of bovine teeth (6 × 6 × 2 mm) were prepared, and color (Easyshade, VITA) and microhardness (HMV‐2, Shimadzu) readings were performed. All the specimens were bleached using 22% carbamide peroxide (22%CP), except for the control group, and then separated into seven groups (n = 10) according to the interaction of toothpaste (whitening, conventional, and whitening with peroxide) and mouth rinse (whitening and conventional). The study simulated 1 year of toothbrushing (Pepsodent, MAVTEC) and mouth rinse by immersion. After that, final color and microhardness measurements were performed. Data were analyzed by one‐way ANOVA, Tukey's test (P < .05). Results The group submitted to 22%CP + whitening toothpaste + whitening mouth rinse showed higher color maintenance (P < .05) than the control group. The perception of whitening of teeth (ΔWID) was higher than the color change (ΔE00). There was a decrease in microhardness after treatment with 22%CP + conventional toothpaste + whitening mouth rinse. Conclusions Over‐the‐counter products can help with the maintenance of tooth whitening after bleaching with carbamide peroxide; however, special attention should be given since the association of products can also reduce the microhardness of the dental enamel. Clinical significance The association between whitening toothpastes and mouth rinses might be beneficial for maintaining color during 1 year after bleaching treatment.

BACKGROUND Misleading online content continually propagates possible adverse effects of fluoridated oral care products and water, although their essential role in preventing and controlling dental caries. OBJECTIVE This study aims to evaluate the patterns of psychophysiological reactions of adults after the consumption of online fluoride-related information and disinformation. METHODS A two-armed, single-blinded, parallel, and randomized controlled trial will be conducted with 58 parents or caregivers of children who attend the Clinics of Pediatric Dentistry of the Bauru School of Dentistry, considering an attrition of 10% and a significance level of 5%. The participants will be blocked randomized with randomly selected block sizes to test and intervention groups, being respectively exposed to fluoride-related information or disinformation presented on a computer, with simultaneous monitoring of their psychophysiological reactions, composed by the analysis of heart rate and 7 facial features (mouth outer, mouth corner, eye area, eyebrow activity, face area, face motion, and facial center of mass). Following, participants will respond to questions about the utility and truthfulness of content, their emotional state after the experiment, eHealth Literacy, oral health knowledge, and socioeconomic characteristics. The Shapiro-Wilk and Levene tests will be used to determine the normality and homogeneity of data, which will indicate further statistical analyses for elucidating significant differences between groups, using parametric (Student t-test) or nonparametric (Mann-Whitney U test) analyses. Also, multiple logistic regression models will be developed to evaluate the influence of distinct variables on the psychophysiological aspects. Only factors with significant Wald statistics in the univariate analysis will be included in the multiple models (P<.20). Furthermore, the ROC curve analysis will be performed to determine the accuracy of remote heart rate concerning measured heart rate. For all analyses, P values <.05 will be considered significant. RESULTS At this moment, no volunteer was recruited. From June 2022, parents and caregivers who frequent Clinics of Pediatric Dentistry at the Bauru School of Dentistry will be invited to participate in the study. CONCLUSIONS This randomized controlled trial aims to elucidate differences between psychophysiological patterns of adults exposed to true or false oral health information. This evidence may support the development of further studies and digital strategies, such as neural network models to automatically detect misinformation available on the Internet. CLINICALTRIAL This study was reviewed and approved by the Council on Ethics in Human Research from the Bauru School of Dentistry (CAAE: 53483821.0.0000.5417), registered in the Brazilian Clinical Trials Registry (RBR-7q4ymr2), and assigned with the universal trial number U1111-1263-8227.

RESUMOCom o objetivo de superar as formas de ensino tradicionalmente desenvolvidas para a formação dos alunos de graduação em técnicas cirúrgicas odontológicas, desenvolveu-se uma nova prática pedagógica para aprendizagem e prática avaliativa com a incorporação de estratégias do tipo Problem Based Learning -PBL e One-Minute Paper. Nesse processo, ampliamos a exposição do aluno às mais diferentes situações clínicas e estimulamos a interação entre os alunos de graduação e os de pós-graduação para trocarem experiências e discutirem a solução dos casos clínicos durante a última fase da disciplina no curso de graduação. Neste artigo, apresentamos a experiência com essas estratégias, enriquecida com relatos de alunos de graduação e de pós-graduação. Palavras-Chave:Avaliação da Aprendizagem; Ensino e Aprendizagem. ABSTRACTAiming to surpass the traditional methods of learning used to teach undergraduate students towards the surgical techniques in Dentistry, it was applied a new pedagogical strategy of learning and evaluation including the Problem Based Learning -PBL and One-Minute Paper concepts. In this task, we enhanced the experience of undergraduate students with different clinical cases and inspired more interactions between graduate and undergraduate students in order to generate a debate seeking the resolution of clinical cases during the last phase of the discipline in the undergraduate program. In this article we present our experience with this new strategy and real testimonials of undergraduate and graduate students. Keywords: Learning Evaluation; Teaching and Learning. IntroduçãoO planejamento de casos clínicos em Odontologia exige um conjunto de informações que podem ser agrupadas em: i) conhecimento de técnicas operatórias; ii) aplicação de materiais; iii) recursos diagnósticos; e iv) habilidades cognitivas. No entanto, a percepção de que cada caso clínico é um paciente diferente a ser examinado individualmente, no contexto da realidade de cada paciente, exige um amadurecimento do aluno que geralmente é longo e que normalmente acontece através da experiência e do contato direto com o problema nas atividades clínicas de rotina do curso de graduação. A limitação do aprendizado através de treinamento em contato direto com o problema é a difícil possibilidade de exposição aos diferentes cenários que aparecerão na vida profissional.Com o objetivo de aumentar a exposição do aluno às mais diversas situações clínicas e de estimular a interação entre os alunos de graduação e os de pós-graduação para trocarem experiências, a disciplina de Periodontia III, último estágio de formação da área, dentro da estrutura curricular do Curso de Graduação da Faculdade de Odontologia de Ribeirão Preto, implantou um modelo de aprendizagem interativa e avaliação baseado em provas diárias ao final de cada aula.

Objective: This study aimed to identify and characterize misleading online oral health information. Materials and Methods: 410 websites published in English were retrieved by Google Advanced Search and screened by 2 independent investigators, who compiled false messages through content analysis. Afterward, 318 content items were divided in consensus as G1 - informationally-oriented misinformation, G2 - misinformation with interests, G3 - misinformation with interests produced or propagated by dental professionals, and G4 – misinformation with political interests. Their presence on social media and fact-checking agencies was determined using CrowdTangle and Snopes. Data were evaluated by descriptive analysis and Cramer’s V test to compare distinct categories. Results: The main issues associated with misleading content items were gum diseases (12.0%), root canal treatment (11.6%), toothache (10.4%), fluoride (10.4%), and dental caries (9.8%), highlighting recommendations for natural products usage, toxicity concerns, and anti-fluoridation propaganda. Most misinformation (41.9%) was allocated in G3, which exhibited a statistically higher frequency of financial interests than other groups. Besides, falsehoods were considerably identified on Facebook (62.9%) and Instagram (49.4%), especially G3 and G4. Nevertheless, Snopes has already debunked only 5.9% of these content items.Conclusions: Misleading information was predominantly produced or propagated by dental professionals mainly motivated by financial interests and usually linked to alternative/natural treatments diffusion. Although these items were shared on social media, fact-checking agencies seemed to have insufficient knowledge about their dissemination.Clinical Relevance: Dental teams need to be conscious of false oral health content to improve the quality of their relationship with patients through adequate communication.
