Erosive potential of soy-based beverages on dental enamel.

BACKGROUND: This study aimed to investigate the erosive potential of soy-based beverages in comparison to fruit juices of the same flavor. METHODS: Human enamel blocks were randomly divided into 9 groups (n = 8), according to the beverage category (soy or non-soy juices). The initial pH, TA and ß at the original pH value were measured in triplicate. The composition of calcium, phosphate and total protein was analyzed using the specific colorimetric method. The fluoride analysis was performed using a selective electrode. The degree of saturation (DS) and the critical pH (CpH) of each beverage with respect to hydroxyapatite (HAp) and fluorapatite (FAp) were calculated using the computational software. Enamel samples were immersed into 67.5 mL of each drink for 120 minutes. Enamel surface loss (ESL) and differences in surface roughness (ΔRaE-S) were analyzed by a 3D non-contact profilometer. RESULTS: Non-soy beverages exhibited the lowest pH values (2.93 to 3.40). The highest values of calcium concentration were founded in soy-based formulations. Juices with soy in their composition tend to have high DS when compared with non-soy based beverages (p = .0571). Soy beverages produced less ESL than non-soy beverages (p < .05). ΔRaE-S was not significantly different between the categories. The ESL and ΔRaE-S were positively correlated with initial pH and buffering capacity in soy-based beverages. On the other hand, in non-soy beverages, the ESL was negatively correlated with the TA to 7.0 and the fluoride composition whereas the ΔRaE-S was negatively correlated with the TA to 5.5. CONCLUSIONS: The erosive potential of soy beverages was lower than non-soy based beverages.

Influence of Fluoridated Groundwater and 1,100 Ppm Fluoride Dentifrice on Biomarkers of Exposure to Fluoride.

This research aimed to determine the influence of fluoridated groundwater and 1,100 ppm fluoride dentifrice on biomarkers of exposure to fluoride in preschoolers. A cross-sectional study was performed on thirty preschoolers recruited from naturally fluoridated and non-fluoridated areas (n=15). Total Daily Fluoride Intake (TDFI) from diet and dentifrice, and Daily Urinary Fluoride Excretion (DUFE) was measured over 24 h. Nails samples were collected twice during 30 days. Fluoride analyses were performed using a fluoride-ion-specific electrode. Data were evaluated using the Student and paired t-test, Pearson correlation analysis, multiple linear regression analysis (α≤0.05). Fluoridated groundwater and dentifrice were the dominant sources (r2 > 0.83) of TDFI in children from a naturally fluoridated and a non-fluoridated area, respectively. A positive correlation between TDFI and DUFE (r=0.50), and between [F] in fingernails and toenails (r=0.60) were found in children from a naturally fluoridated area. The [F] in nails of finger and toe were not correlated to TDFI. The consumption of fluoridated groundwater influenced the fluoride concentration in urine. In addition, the use of 1,100 ppm fluoride dentifrice did not influence the fluoride concentration in urine and fingernails.

Integração ensino serviço: percepção de agentes comunitários de saúde sobre capacitação / The integration of teaching service: community health agents perception of training

O objetivo deste estudo foi conhecer a percepção dos Agentes Comunitários de Saúde sobre capacitações desenvolvidas por estudantes e professores de um curso de odontologia do nordeste do Brasil. É um estudo com abordagem qualitativa em que se utilizou a técnica do grupo focal e para interpretação dos dados, a análise de conteúdo. Nas capacitações, foi possível identificar a existência prévia do entendimento sobre a saúde bucal, evidenciando necessidade de ações no sentido de ampliar e ressignificar olhares. A visão de atenção integral, não meramente clínica, foi um ponto marcante, demonstrado em falas, que retratam a importância dos equipamentos sociais existentes e da execução de atividades. Os agentes comunitários de saúde relataram que as ações em parceria com a universidade são importantes para a ampliação das atividades desenvolvidas. Percebe-se que as capacitações foram espaço de diálogo, que geram reflexos no processo de trabalho dos agentes, apontando caminhos possíveis para serem trilhados.

The study intended to learn about the perception of Community Health Agents regarding skills developed through educational activity by students and teachers of a course in dentistry in northeastern Brazil. This is a qualitative study that used the focus group technique and content analysis for interpretation of the data. In the training sessions, the existence of a prior understanding of oral health could be seen, highlighting the need for actions to broaden and reframe perspectives. The vision of integral, not merely clinical, attention was a notable point, demonstrated in the discourse that portrayed the importance of existing social equipment and of carrying out activities. The community health agents reported that the actions in partnership with the university are important for expansion of the activities developed. We can see that the training sessions were a space for dialogue that generates reflections on the work process of the agents, pointing out possible paths to be followed, based on the empowerment of individuals.

Tooth loss in middle-aged adults with diabetes and hypertension: Social determinants, health perceptions, oral impact on daily performance (OIDP) and treatment need

Background: This study aimed to explore the association between tooth loss and social determinants, health selfperceptions, OIDP and self-concept of dental treatment need in middle-aged adults with diabetes and hypertension. Material and Methods: A cross-sectional study was developed with 212 hypertensive and diabetic middle-aged adults (50-65 years). Data were collected from clinical examinations (DMFT) and a questionnaire regarding socioeconomic status, dental health assistance, self-perceptions of oral and general health, OIDP, and the self-concept of dental treatment need. Tooth loss was dichotomized considering the cutoff point of 12 (Model I) or 24 missing teeth (Model II). Data were analyzed using Chi-square, Fisher's exact test and logistic regression (p≤0.05). Results: Tooth loss was significantly associated with variables such as last dental visit, reason for dental visit, OIDP, perception of dental treatment need, and general self-perception (Model I). Schooling, last dental visit, oral health self-perception and perception of dental treatment need were significantly associated with tooth loss in the Model II. When Model 1 and 2 were adjusted, they demonstrated that last dental visit and perception of dental treatment need were predictor variables. Conclusions: The annual dental visit and the self-concept of dental treatment need were associated with tooth loss, demonstrating that these variables reduce the tooth loss prevalence (AU)

Low-level laser therapy and anesthetic infiltration for orofacial pain in patients with fibromyalgia: a randomized clinical trial

Background: To compare the analgesic effect of anesthetic infiltration of lidocaine 2% and low-level laser therapy (LLLT) by GaAlAs into tender points of patients with orofacial pain and fibromyalgia (FM). Material and Methods: A randomized clinical trial was performed with adults (N=66) that were allocated into two groups (1:1): Group A received LLLT irradiation by Diode Laser GaAlAs (780nm) with expositions twice a week during six weeks and Group B was treated with anesthetic infiltration of lidocaine 2% without vasoconstrictor once a week for four weeks. The pain assessment included the Visual Analogic Scale (VAS) and tenderness to palpation. Results: No dropout and adverse effect was observed during the study. The pain decreased significantly in each group after the treatment (p=0.0001, β=1.0), even though no statistical difference was found between both treatments (p=0.46, β= 0.82). The presence of tender points decreased after both treatments, with responsively in some types of masticatory muscles (p<0.05) except posterior temporalis muscle. The patients' perception showed that both treatments were effective and a few patients reported that the treatment did not improve welfare. Conclusions: The LLLT by GaAlAs and anesthetic infiltration of lidocaine 2% were equally effective to control orofacial pain in FM individuals (AU)
