Tooth color is one of the characteristics that define a smile as attractive, and Dentistry offers tooth whitening as an option for achieving this purpose. However, this therapy is almost always accompanied by an inconvenience: dentin sensitivity. The objective of this study was to analyze two 35% hydrogen peroxide-based materials, used in different clinical time intervals to evaluate not only the efficacy of color change, but also how long dentin sensitivity lasts, and at what times is it most exacerbated. A total of 24 volunteers were selected. The maxillary arch was divided at the midline, forming the Right Group (RG) composed of the right maxillary hemi-arch (tooth 11-15) and Left Group (LG) composed of the left maxillary hemi-arch (tooth 21-25). The mandibular arch formed the control group CG. The RG received 35% hydrogen peroxide-Whiteness HP®-FGM Produtos Odontológicos, Joinville, SC, Brazil in three sessions of 45 minutes each (Material 1) and LG received 35% hydrogen peroxide-Pola Office®-SDI Limited, Bayswater, VIC, Australia in three sessions of 24 minutes each (Material 2) with an interval of one week between sessions. Color was evaluated visually by means of the Vitapan Classical Scale (Vita Zahnfabrick, Bad Säckingen, BW, Germany) at the beginning and end of each session, and 12 days after the last session. There was no statistically significant difference (p<0.05) in relation to bleaching potential, and intensity of sensitivity when the two materials used were compared, except in the second (T=0h) (P=0.047) and third sessions (T=12h) (P=0.033) in which Material 2 demonstrated a lower level of sensitivity compared with that of Material 1. Relative to the duration of sensitivity, this gradually diminished over the course of time, not exceeding 48 hours (P=1.000). There was no difference between the products with respect to bleaching power, and hydrogen peroxide used for a shorter time generated less tooth sensitivity.
Objective: To determine the profile of children from 6 to 12 years of age, in relation to anxiety towards dental treatment and evaluate the main factors that trigger anxiety in this population. Methods: The sample was composed of 200 children with an average age of 8.5 years who attended the Clinic of the School of Dentistry of the Federal University of Campina Grande and the Basic Healthcare Units of the municipality of Patos, Paraíba, Brazil between June 2015 and May 2016. Anxiety was assessed using the Dental Anxiety Scale and the Venham Picture Test. The Chi-Square test and Fisher’s exact test were used to explore the level of significance of the associations between the variables Results: Anxiety was observed in the majority of children (Dental Anxiety Scale - 89% and Venham Picture Test - 70.5%) and the predominant levels were low to moderate. The child´s age group was significantly associated with anxiety (p=0.014) by the Venham Picture Test, while gender did not present this correlation. Anxiety was influenced by all the factors studied: making the appointment, waiting room, rotary instrument and periodontal scaling. Conclusion: The majority of children presented anxiety and the trigger factors: making the appointment, waiting room, rotary instrument and periodontal scaling contributed considerably to its development.
Objetivo: avaliar o padrão de utilização dos serviços de saúde segundo determinantes sociais e qualidade de vida de diabéticos tipo 2, assistidos pela Estratégia Saúde da Família de um município Paraibano durante a pandemia da COVID-19. Método: estudo transversal de base populacional e abordagem quantitativa, com utilização de estatísticas descritivas, bivariadas e multivariada através da modelagem de Árvore de Decisão usando o algoritmo Chi‑squared Automatic Interaction Detector e Análise de Cluster. Resultados: Em sua maioria, os participantes utilizaram o serviço público de saúde sem regularidade (51,9%), apresentaram baixo impacto da doença na qualidade de vida (63,4%). As variáveis: renda mensal familiar, situação empregatícia, e quantidade de complicações sistêmicas, demonstraram desempenhar papel relevante na compreensão da utilização do serviço de saúde entre os portadores de DM. Conclusão: a disparidades relacionadas aos determinantes sociais, comportamentos em saúde e ao impacto do diabetes na qualidade de vida, podem explicar o padrão de utilização do serviço de saúde por esses usuários, além de situações excepcionais, como o advento da pandemia por COVID-19 que impôs rotinas excepcionais aos serviços de saúde, além das restrições sociais.
