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.

Influence of the dental prosthetic status on self-perceptions of health and treatment needs: A cross-sectional study of middle-aged adults with chronic disease.

BACKGROUND: Subjective aspects of dental prosthesis need in middle-aged adults are poorly explored, especially when the population presents chronic diseases. Objectives: To investigate if the use and necessity of dental prosthesis influence the self-perceptions of health and dental treatment need in middle-aged adults with chronic diseases. MATERIAL AND METHODS: A cross-sectional study was performed in 210 middle-aged adults. Socio-demographic aspects, dental services use, oral and general perceptions of health, dental treatment need and OIDP were assessed using a standardized questionnaire. One trained dentist evaluated the use and necessity of dental prosthesis. Data were analyzed using Chi-square and multivariate logistic regression (p<0.05). RESULTS: The use of dental prosthesis showed a proportion of 2.2:1 for upper to lower arch. Dental prosthesis need was largely prevalent (90 and 95% in upper and lower arch, respectively). The self-perceptions of dental treatment need and oral health were associated with the use and necessity of dental prosthesis (p<0.05), which could not be observed in relation to the general self-perception. The adjusted model demonstrated that the subjective necessity of dental treatment was 16.04 (1.92-133.7) fold higher in individuals with necessity of rehabilitation in the lower arch. Besides, a positive self-perception of oral health (satisfied) was 2.59 (1.38-4.85) more expressive in individuals that used a dental prosthesis in upper arch. CONCLUSIONS: The self-perception of oral health was influenced by the use of maxillary dental prosthesis in individuals with chronic disease. Moreover, individuals were more likely able to perceive treatment need when the lower jaw was affected by tooth loss. Key words:Tooth loss, epidemiology, personal satisfaction, aged, chronic disease.

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)

Perception of children and mothers regarding dental aesthetics and orthodontic treatment need: a cross-sectional study.

BACKGROUND: The normative orthodontic treatment need, established by dental professionals during the dental appointment, becomes ineffective when it does not evaluate all the factors that influence the decision-making process, including individuals' perception and satisfaction with their dental appearance. Therefore, the purpose of this study was to investigate the perception of children and their mothers as regards orthodontic treatment need and satisfaction with dental aesthetics and test if these variables are associated with the objective orthodontic treatment needs, assessed by the Dental Aesthetic Index (DAI). METHODS: A cross-sectional study was conducted on 308 children aged 12 years, and their mothers were randomly selected by cluster sampling (primary schools). The variables "orthodontic treatment need," "satisfaction with chewing," and "dental appearance" were assessed by means of a questionnaire. The questions were answered individually at school or home, in cases of children or mothers, respectively. DAI was assessed to make an objective clinical assessment. The variables were dichotomized and statistically analyzed by the chi-square and Fisher's exact tests, contingency coefficient C, and logistic regression. RESULTS: The results of the clinical evaluation (DAI) were statistically associated with the perception of orthodontic treatment need and satisfaction with dental appearance in children (p ≤ 0.01). However, no association was observed with regard to satisfaction with chewing and DAI (p = 0.10). The children's perception of orthodontic treatment need and satisfaction with the appearance of their teeth was statistically associated (p ≤ 0.01) with their mothers' perception. Maxillary overjet, maxillary and mandibular misalignment, and dental crowding were associated with the orthodontic treatment need by children and their mothers, with p value -0.05 and 5 % level of significance. Maxillary overjet was a significant predictor for the perception of orthodontic treatment need in children (OR 1.86, 95 % CI 0.98-3.55) and mothers (OR 3.02, 95 % CI 1.54-5.92). CONCLUSIONS: Children and parents realize the need for orthodontic treatment according to the different types of malocclusion, as noted in the association between orthodontic treatment need and dental appearance perceived by children and their mothers, which was also observed-with low correlation-with regard to DAI.

Enxerto Òsseo Homógeno para Reconstrução de Maxila Atrófica / Allogenic bone grafts for reconstruction of Atrophic Maxilla

Com o advento da implantodontia moderna, tem sido cada vez maior a utilização de enxertos em bloco para reconstrução de estruturas ósseas perdidas. O objetivo deste artigo é discutir através de um caso clínico a reconstrução óssea de rebordo alveolar, utilizando osso homógeno, proveniente de um banco de ossos, na reconstrução de uma maxila comprometida, por meio do aumento da espessura do rebordo alveolar, possibilitando, dessa forma, a instalação de implantes osseointegráveis e suas respectivas próteses. Esse tipo de enxerto ósseo oferece como principais vantagens a eliminação da abordagem de um segundo sítio cirúrgico e quantidade suficiente de osso, o que reduz o tempo e a morbi¬dade. Portanto, o enxerto homógeno fresco congelado é uma alternativa para as reconstruções dos rebordos atróficos devido a sua capacidade de remodelação, incorporação e qualidade que permitem resistir às cargas funcionais quando da instalação de implantes osseointegráveis Foi concluído que esse enxerto é uma alternativa viável, segura e pouco traumática para o aumento ósseo com finalidade reabilitadora, embora haja a necessidade de mais pesquisas em longo prazo.

With the advent of modern implantology has been increasing the use of block grafts for reconstruction of lost bone structures. The aim of this paper is to discuss through a case study of the alveolar ridge bone reconstruction using fresh frozen allogenic bone, from a bone bank in the reconstruction of a jaw compromised by increasing the thickness of the alveolar ridge, allowing, thus, the installation of dental implants and their prosthetic limbs. This type of bone graft offers major advantages such as elimination of the approach of a second surgical site and sufficient quantity of bone, which reduces the time and morbid ¬ ity. Therefore, the fresh-frozen allogenic graft is an alternative for the reconstruction of atrophic ridges due to its ability to remodel, incorporation and quality that allow withstand functional loads when the installation of dental implants was concluded that graft is a viable, safe and less traumatic to the bone augmentation with rehabilitative purpose, although there is a need for more research on long term.
