Efetividade do uso tópico de fluoreto e da escovação no controle de cáries produzidas "in vivo"

The objective of this clinical study was to evaluate the effectiveness of the toothbrushing with and without fluoride and the daily fluoride rinse (NaF 0.05%) on produced white spot, in vivo. This was a clinical study, controlled, randomized and triple blind. Thirty patients were selected for orthodontics reasons from Orthodontics Specialization Course at the Brazilian Dental Association - Section of Rio Grande do Norte. In this study it was used 4 bicuspid upper and lower. They had orthodontic reason for extractions, in 35 days, at least. The sample had one hundred and twenty teeth that received orthodontic bands. The bands were fixed with polycarboxylate cement, and there was a space standardized between bands and one surface of teeth. The four bicuspid of each patients were randomized and nominated as A, B, C and D. These nominations determinated the sequence of the extractions and what was done in each tooth. All the patients had been submitted to the toothbrushing with or without fluoride for 35 days. After this period, the A tooth of each patient was extracted to serve as control. The others teeth (B, C and D) were extracted one by each week. The entire sample was analyzed through the clinical examination and by laser fluorescence (DIAGNOdent®) in three different times: before orthodontic bands, 28 days after fixed and then removed the bands and, the last one, 07 days after one of the three treatments (toothbrushing with or without fluoride, tooth paste with fluoride and mouth rinse with fluoride). At the beginning all groups (A, B, C and D) had the same conditions, no significant difference was found. The same situation was found in a clinical examination. The results of the DIAGNOdent® for the groups that used tooth paste without fluoride, with fluoride and mouth rinse with fluoride, after 28 days, there was no significant difference. Clinically, the white spot was formed in all teeth after 28 days. When it was compared the three treated groups, the group without fluoride in tooth paste had worst result than the others groups. But there was no significant association between the number of active and inactive white spots and the type of treatment that the teeth had received. The demineralization of the enamel surface, under the orthodontic bands, it happened in a few weeks. The exposition of the white spots in oral environmental resulted in an improvement, but it was not enough to return to the values from the base line, either for the toothbrushing and/or the use of fluorite mouth rinse. Mouth rinse and toothpaste with fluoride have showed to reduce the incidence of demineralization in the enamel, but none seems to be superior to another one in an in vivo study

Avaliação de lesões brancas de cáries: um estudo de prognóstico

Objective: The aim of the present study is to assess the current situation of white enamel lesions on vestibular surfaces of permanent upper incisors, diagnosed 6 years ago, without clinical intervention. Methods: A prospective study reassessed 53 students of both sexes, aged between 13 and 18 years old, all attending the public school system in Natal, Brazil. Data collection was performed by duly calibrated examiners, and a clinical chart consisting of demographic data on dental caries, oral hygiene, and gingival condition was prepared. A tactile-visual examination was conducted using a clinical mirror and periodontal probe. Data compilation and analysis were carried out using a SPSS software. In this analysis the chi-squared test was used for qualitative independent variables. To identify the net effect of treatment, multiple logistic analysis with forward stepwise model selection was performed. Results: The final sample was composed of 106 lesions in the 53 individuals, with mean age of 15.02 years, visible plaque index (VPI) of 23.34%, and gingival blood indices (GBI) of 25.92%. A statistically significant relationship (p = 0.003) was found between initial DMFS and prognosis of white enamel lesion. Conclusions: We observed that past caries experience and dental plaque were the main predictive factors for negative lesion outcomes, demonstrating the need for oral hygiene control through continuing preventive measures

Break: o grito corporal da periferia

In order to question a sociology as it considers appropriate the body dimensions, which contributes in a mean singular in relation to body, not only as a matter, but mainly as a producer of knowledge, our research shows a reflection on corporality as the production of knowledge and to understand different perspectives and social logic here in contemporaneity, whose rationality seems to be placed in question through a performance expressed, a lot of 'breaks', including the space, which the dancer break appropriates of a reversed form and not more than linear. Our problem is the possibility of a greater understanding of this young body with dance the break, is not only 'breaking' his body, but fluent in their own body fragments, producing probably a break in relation to a dominant power established, by creating a kind of 'social resistance' to provide another sense for his life, out of the senses by the dominant of a social field. This is the area of production of knowledge, of the 'body' that cries keep our eyes, the challenge of dive in the depth of gestures, beyond the physical structure, restoring in a strong political constitution and cultural in so far as this body faces. The body as spectacular becomes 'cause and effect' of communication, this body is not only individual, it is not expression only for itself; when the young dance outside their walls individuals, makes it relational, turning to relate with the other, with the space, time and the world. The methodological point of view, to study this corporality in element break, the body as language of senses, we considered withdrawals in the field, observations of movements of the universe of break creative dance, performance and analysis of "attitudes" (expression peculiar world hip hop ), as well as my experience with dancing in the street interventions through 'urban' and our own attitudes to the object of research which challenges us academically and, it all, existentially

O SABOR DO SANGUE: uma análise sociocultural do chouriço sertanejo

Cette étude propose de réaliser une lecture du chouriço, une confiture faite avec du sang, fabriquée et consommée dans tout le Seridó potiguar. Grace à l observation ethnographique réalisée entre 2003 et 2007, nous découvrons une économie domestique, une organisation sociale, des formes de sociabilité et de solidarité contruites autour de l élevage des porcs et des pratiques culinaires. Cette observation a aussi révélé un style alimentaire, des discours, des perceptions, des goûts et des comportements relatifs à la consommation de la confiture qui résultent, em grande partie, de la relation dynamique entre une norme idéalisée et des pratiques observées qui ont montré des tensions et des contradictions entre ce qui est dit et ce qui est fait. Avec l étude du chouriço, nous reálisons une lecture de la culture alimentaire; notre intention a été de problématiser l applicabilité des normes sociales et leur inscription dans la réalité. Ainsi, em faisant une analyse simbolique du chouriço, nous considérons ensemble les aspects sociaux et symboliques et nous décrivons comment les habitants du Seridó pensent leur alimentation en corrélation avec les pratiques alimentaires et les formes de sociabilité. L étude a révélé que les príncipes de confiance et d interconnaissance, fondés sur les liens sociaux, structurent les relations constituées autour de l élevage des porcs et de la production, de la distribution et de la consommation du chouriço. D un point de vue symbolique, le sang est central dans le style alimentaire: il apparaît comme une anti-nourriture et révèle des prohibitions et des transgressions. La contrastivité entre les pratiques et les discours est en relation directe avec la nature du chouriço, fait avec le sang du porc et considéré comme un dessert

Programa de odontologia para bebês: uma avaliação quantitativa e qualitativa

The objective of this study was to evaluate a baby dentistry program which has been in the city of Natal for five years. The research was based on two analysis: a quantitative one, which tried to check caries prevalence in 52 children supported by the program and a qualitative one, which, through interviews carried out with the mothers, using the focus group technique, tried to realize the effect of the program their attitudes related to the care of their children´s oral health. For the quantitative analyses of caries prevalence there was the use of def-s and knutson rates and the values obtained were shown in a descritive and analytical way.The results showed that 4.2% of babies ranging 24 to 36 months old presented carie disease. Children from 36 to 48 months old and above 48 months old presented 18.2% and 16.7% carie prevalence respectively.The def-s averages found in ages 24 to 36, 36 to 48 and 48 to 60 months old were 0.08; 0.40 and 1.16 respectively, considered as being equally low, going along with Knutson rates. The qualitative analyses showed a high level of the mothers` satisfaction, considering the access,practitioner-patient relationship and opportunity to keep the oral health. Children supported by the program showed a low carie prevalence and the program turned out to be effective under the mothers` point of view

Eficácia do cimento de ionômero de vidro como selante oclusal sobre a paralisação de lesões cariosas em dentina

Dental caries consists in a multifactorial and dynamic process. The knowledge of the ionic interactions among dental tissues and dental biofilm make possible its understanding as a process that can be stopped. Recently, the use of sealants have lost its function as preventive agent and passed to be argued as a possible therapeutical agent. This happens by hindering the substratum flow to the lesion inner and, therefore, controls the advance of the process. This study aimed to evaluate glass ionomer cement as a not invasive technique of treatment in occlusal caries without clinical cavitation, but with dentinal involvement. The research was accomplished using a controlled clinical trial with two groups (experimental and control) in 38 subjects (8-18 years) with 51 molars. The teeth of the experimental group were sealed with glass ionomer cement (Vidrion-R, S.S.White, Juiz de Fora, Brazil) and the molars control did not suffer intervention. The experimental group was followed by a year and the control by 8 months due the progression of the carious injury. Both groups were reevaluated to each 4 months with the use of clinical, radiographic and laser fluorescence (DIAGNOdent®) examination. The analysis of the clinical evaluation did not observe a significant difference between experimental and control groups. However, analysis with radiographic and laser fluorescence (DIAGNOdent®) examination observed a significant difference (p> 0,05) between groups, demonstrating a wors condition to the group without intervention. The results suggest that glass ionomer cement as sealant can be efficient to paralyze dentinal caries without clinical cavitation

Influência do pré-aquecimento na adaptação marginal de dois materiais seladores de fóssulas e fissuras, analisada através de tomografia de coerência ótica

Among the non-invasive techniques employed in the prevention of caries highlights the sealing pits and fissures which is a conservative maneuver, in order to obliterate them to protect them from attack acid bacteria. Influenced by the studies of pre-heating composite resin, which has experienced great improvement in some of their physical properties, this study aimed to evaluate in vitro the superficial and internal marginal adaptation of different materials and sealants in pre-heating or not. A total of 40 extracted human third molars (n=10) that had their occlusal surfaces prepared to receive sealant. We tested two types of sealing materials: resin sealant (Fluoroshield) and low-viscosity resin (Permaflo), where 50% of previously received heated material and the other half received sealant material at room temperature. All samples were subjected to thermal cycling and pH, simulating a cariogenic oral environment, and later were analyzed appliance OCT (optical coherence tomography). The images obtained alterations were recorded and analyzed statistically. Change was considered as the emergence of bubbles, gaps and cracks in the sealant. Comparisons of the same material, assessing the fact that it is not sealed or preheated material, as well as comparisons between different materials subjected to the same temperature were carried out. The nonparametric Tukey test was used (p < 0,05). The results showed that there was statistically significant difference between both the materials analyzed, as between the situations in which the sealant material was submitted (preheated or not). On the issue of marginal adaptation and internal surface, seen through Optical coherence tomography, may suggest that there is a difference between the use of one type or another of the sealing material analyzed, with superiority attributed to resin Permaflo compared to sealant Fluroshield, telling is the same for the different techniques used

Análises clínicas, radiográfica e microscópica de molares permanentes sem ou com lesão de cárie na superfície oclusal

O presente trabalho, objetivou avaliar comparativamente o diagnóstico clínico, radiógráfico e histológico de molares permanentes humanos sem ou com lesão de cárie na superfície oclusa!. Vinte e quatro dentes que estavam armazenados em formalina a 10% foram selecionados e em seguida submetidos a um exame clínico, através da inspeção visual, onde foram separados em 3 grupos: grupo 1 (G1), formado por dentes hígidos; grupo 2(G2), por dentes com pigmento na superfície oclusal e grupo 3(G3), aqueles com lesão de cárie na oclusal. Este exame foi realizado com auxílio de luz artificial proveniente de um refletor odontológico, sem qualquer manipulação da superfície. Para cada dente foram realizados duas tomadas radiográficas com e sem tela milimetrada, no sentido vestibulo lingual por um dos avaliadores, simulando uma radiografia interproximal, onde o feixe incidiu perpendicular ao longo eixo do dente. Em seguida os dentes foram preparados histomorfologicamente para coloração com hematoxilina e eosina e análise microscópica. Pela avaliação dos resultados a partir da amostra de 100%, foi possível concluir: 1) Os dentes clinicamente considerados hígidos (G1) apresentaram radiograficamente 74,99% de ausência de imagem radiolúcida e em 25% presença desta imagem na Junção Amelo¬dentinária e microscopicamente ausência de cárie em 100%; 2) os dentes que clinicamente apresentaram fissura pigmentada' (G2) notou-se em 33,33%, ausência da imagem radiolúcida e em 66,66% presente esta imagem na junção amelodentinária, 100% de ausência de cárie através da análise microscópica; 3) clinicamente, os dentes que apresentaram lesão de cárie (G3), radiograficamente foram comprovados 100% de imagem radiolúcida sugestiva de cárie e microscopicamente dos 100% destas, foram considerados cáries rasa (16,66%), média (61,10%) e profunda (22,22%) respectivamente
