Resumo O tabagismo compromete a expectativa e a qualidade de vida das pessoas. O estudo avaliou se o habito de fumar influencia na prevalencia da doenca periodontal em idosos do municipio de Londrina – PR. A amostra de 504 idosos fisicamente independentes, cadastrados em Unidades Basicas de Saude; foi aleatorizada e estratificada por genero e faixa etaria. Na avaliacao clinica foram utilizados o Indice Periodontal Comunitario (CIP) e o Indice de Perda de Insercao Periodontal (PIP). O CIP avaliou a presenca ou nao de sangramento gengival, calculo e bolsa periodontal. A cavidade bucal foi dividida em sextantes onde se registrou a pior condicao dos dentes indice 16/17, 11, 26/27, 36/37, 31, 46/47. O PIP avaliou a insercao periodontal nos locais (0-0/3mm, 1-4/5mm; 2- 6/8mm; 3- 9/11mm, 4-12mm ou mais). Na ausencia dos dentes indice ou menos de 2 dentes, excluiu-se o sextante. O habito de fumar foi avaliado, categorizando as amostras em fumante, ex-fumante e nao fumante. A dependencia nicotinica foi avaliada pelo questionario de tolerância de Fagerstrom. Houve diferenca estatistica na prevalencia de sangramento (p=0,001) entre os generos masculino (54,8 %) e feminino (45,2 %). Houve relacao entre a presenca de sangramento e calculo (p=0,004) em 89% dos idosos. Houve diferenca da PIP entre os generos (p=0,000), com menos sextantes sadios no genero masculino (24,2%). Houve influencia do fumo nos sextantes sadios para PIP (p=0,006). Nao foram observadas diferencas para as demais associacoes. A doenca periodontal foi influenciada pelo genero e pelo habito de fumar.

The association between the genotypic diversity of Streptococcus mutans and risk factors for dental caries in children attending an educational program in the public sector was investigated. Twenty-one children (2-7 years old) who presented at least three risk factors were allocated into two groups: caries free (n = 12); with caries activity (n = 9). Initially, 210 isolates of S. Mutans were analyzed through AP-PCR and in the second intervention (after 12 months), new evaluation of risk factors and dmf-t index was carried out, followed by statistical analysis of the data (Simple Logistic Regression and Chi-square Test). There was an association between genotype diversity and caries (p = 0.05). It was found that 66,6% of the caries-free children had one genotype, while 77.7% in the group with caries had two or more genotypes. Having two or more genotypes increased by seven times the chance of injury. Genotypic diversity was associated with inadequate eating habits and oral hygiene pr...

The study of medicinal plants with antimicrobial action is a current issue, mainly due to the increase of bacterial resistance and the need for new antimicrobials with equal or greater efficacy, low cost and low side effects. The constant search for new products with bactericidal potential on oral microorganisms, mainly of natural origin, has grown considerably in recent years.The objective of this research was to evaluate the efficiency of concentrations of Barbatimão glycolic extract solution (Stryphnodendronadstringens) in inhibiting the bacteria growth associated with in vitro dental caries. Sixteen different concentrations of Barbatimão glycolic extract were prepared (0%, 1.56%, 3.12%, 4.68%, 6.25%, 7.81%, 9.37%, 10.93, 12, 5%, 25%, 37.5%, 50%, 62.5%, 75%, 87.5%, 100%) and the 2% chlorhexidine solution were used as the control group. The prepared solutions were tested on the bacterial strain of Streptococcus mutans. Bacterial growth was observed on plates containing BHI cult...

The objective of this study was to investigate the reproducibility of the International System for the Detection and Evaluation of Caries (ICDAS) for the diagnosis of caries by students of the Master's Degree in Dentistry (n = 25). The occlusal surfaces of human third molars (n = 14) were evaluated by twenty-five (n = 25) students using the ICDAS index and later a questionnaire was applied on demographic and professional context data. The dental crowns were sectioned in mesial to distal direction to obtain slices of 1mm in thickness which were observed in a stereomicroscope (40X) to identify the greatest extension of caries lesion. Data were analyzed by the Chi-Square, Fisher's Exact and Spearman's Correlation Coefficient at a significance level of 5%. There was an influence in the diagnosis of caries among students and teeth, where the majority of those who declared themselves to be safe missed the diagnosis. There was variability between the diagnosis and the proposed ...

In vitro evaluation of the effect of guaraná (GUAR) on cell surface hydrophobicity (CSH), on biofilm formation, and on adhesion of C. albicans to polystyrene, to composite resins, and to buccal epithelial cells (BEC). Lyophilised aqueous extract of GUAR was tested on C. albicans ATCC (90028). The effect of GUAR was evaluated by examining the CSH of C. albicans, as determined by microbial adhesion to hydrocarbons test, by assessing biofilm production and through adhesion assays (microplates of polystyrene, BEC and composites). One nanoparticle (Z350(®)) and two microhybrid (LLis(®), Opallis(®)) composites were tested. Scanning electron microscopy (SEM) was used to analyse adhesion of C. albicans composites. Assays were performed in triplicate and the results analysed by Chi-square test, Kruskal-Wallis test and Dunn&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Multiple Comparison post hoc test at 5% significance level. GUAR did not inhibit growth of C. albicans at any concentration, but it reduced adhesion to polystyrene surface (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). Exposure to GUAR did not change CSH and biofilm formation, but it increased adhesion of C. albicans to the nanoparticle composite (p = 0.042) and reduced its adhesion to BEC (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). SEM confirmed an aggregatory pattern of adhesion of C. albicans to composites. GUAR increased the adhesion of C. albicans to the surface of the nanoparticle composite. However, it reduced the adhesion of C. albicans to BEC and to polystyrene, which reveals its potential use in prevention of oral diseases.

Objective: We investigated the precision and accuracy of methods to detect caries lesions on the occlusal surface in vitro using ICDAS and radiological image. Methodology: Human third molars (n=14) were placed in an acrylic resin base and maintained wet during the study. The occlusal surfaces were visually inspected by three examiners using the International Caries Detection and Assessment System (ICDAS) method. The condition of each tooth was registered by images obtained with Digital Radiography (DR), Microcomputed Tomography (µ-CT) and Histologic Specimen (HS). For each tooth and method utilized in the study, an image was selected based on the largest extension of caries found, wherein the three examiners attributed a score to the lesion in accordance with the visual description of each method. The Kappa index, Fisher’s exact test and the Spearman´s correlation coefficient were used for evaluating reliability and accuracy, with a significance level of 5%. Results: Considerable in...

Background: The bariatric surgery may have negative repercussions on oral conditions. Aim: To evaluate the impact of oral health educational/preventive program developed with patients submitted to gastroplasties. Method: The sample consisted of 109 patients randomly allocated to two groups: intervention group (IG), where they participated in the oral health promotion program that include multiple educational-preventive approaches; control group (CG), where they received usual care from the bariatric clinic staff, without participation in the program. The oral conditions investigated in the pre-operative and postoperative periods of one month (1M) and six months (6M) were: dental caries, periodontal disease, tooth wear, dental plaque and salivary flow. Results: After bariatric surgery, patients in IG presented: fewer changes in enamel (6M: p=0.004), dentin (6M: p=0.005) and gingival bleeding (6M: p<0.0001), reduction in plaque index (1M, 6M: p<0.0001) and increased salivary flo...

ABSTRACT Introduction.-To evaluate the association of the ACE I/D polymorphism with exercise capacity and history of hypertension in physically independent elderly. Summary of facts and results.-The study sample consisted of 57 health elderly and 57 hypertensive elderly. Genotyping for ACE I/D was performed by polymerase chain reaction. The 6-Minute Walk Test evaluates the subject&#39;s functional exercise capacity and was per formed in accordance with the guidelines of the American Thoracic Society. The influence of parameters on the risk of hypertension was assessed by analysis of logistic regression. The significance level for all analyses was P &lt;= 0.05. The elderly with the ACE DD genotype were 1.37 (95%Cl: 1.09-1.71) more likely to be hypertensive than carriers of the allele I (P=0.006). The hypertensive group exhibited a significantly higher BMI than the normotensive group (OR=1.16; 95%Cl: 1.02-1.33), as well as, elderly with impaired exercise capacity were 1.24 more likely to be hypertensive than those with more preserved exercise capacity (95%Cl: 1.09-1.41). Conclusion. The physically independent elderly carriers of the DD genotype showed an impaired exercise capacity and consequently an increased risk of hypertension.

Purpose: The objective of the present study was to evaluate whether sensitivity to bitter taste and perception of sweet taste have an influence on dental caries in urban and rural areas. Materials and methods: The caries experience in 181 children, aged 12 years, from rural and urban areas of southern Brazil, was assessed according to World Health Organization guidelines. Sensitivity to the bitterness of phenylthiocarbamide was determined using the Harris–Kalmus procedure, and the sweet taste thresholds of sucrose were measured by Nilsson and Holm's method. Results: The caries index (DMFT > 0) was 3.73 (SD = 2.26) in the rural area and 3.51 (SD = 2.14) in the urban area. The sensitivity to bitter taste and sweet taste perception showed significant association with the gender of schoolchildren (P = 0.04). Girls were predominant in the high sweet perception taster group (62.3%) and the bitter taster group (59.4%). No significant difference in sweet perception status could be observed between the groups of low and high caries severity. The genetic ability to taste bitterness significantly influenced the levels of caries only in children from the urban area (P = 0.005). Bitter non-tasters presented higher severity of caries. A positive correlation was observed between sensitivity to bitter taste and sweet taste perception among children in the rural (r = 0.42, P = 0.002) and urban areas (r = 0.36, P = 0.001). Conclusions: These findings suggest that the bitter non-tasters are more susceptible to dental caries than the tasters in the urban area.

To analyse the relationship between preference for sweetness, levels of salivary mutans streptococci and levels of caries in low socio-economic 4-5-year-old Brazilian children. A cross-sectional survey. 298 children of both sexes, who, in 1998, were regularly attending public nurseries were randomly selected. Caries experience was assessed according to WHO guidelines. Saliva samples were analysed for mutans streptococci using the spatula method. Children's preference for sugar was measured using the 'Sweet Preference Inventory'. Personal interviews with the mothers were conducted. 255 children completed all aspects of the research, a response rate of 85.6%. 34.9% of them were caries-free. The mean dmf-s was 4.25 (SD 6.16), the decayed component being 3.56 (SD 5.82) and the filled surfaces, 0.69 (SD 1.85). For these pre-school children; male sex (P < 0.01), single parent (P < 0.01), habit of eating or drinking items that contained non-milk extrinsic sugar between me...

Children&#39;s patterns of sugar consumption and dental health status have been associated to their mothers&#39; patterns. As a liking for sweetness has been related to caries levels, this study was carried out to analyse the relationship between sweetness preference and caries experience in mother/child pairs. A cross-sectional survey was conducted on a sample of low socio-economic mothers and their 4-5-year-olds from Maringá-Pr, Brazil. Mothers&#39; and children&#39;s preference for sugar was measured using the Sweet Preference Inventory. Their caries experience was assessed according to World Health Organization (WHO) guidelines. High levels of sweetness preference and caries experience were found in the sample studied. Although not strong, a significant correlation in patterns of sweetness preference (r=0.12, P&lt;0.05) and caries experience (r=0.14, P&lt;0.05) between mother/child pairs was identified. Among the social-demographic variables, only family income was statistically associated with the children&#39;s preference for sweetness (P&lt;0.05). No significant association between sweetness preference and caries experience could be established. The findings of this study suggest that mothers may play an important role on the establishment of their children dietary preferences and patterns of dental health. Also, that the socio-economic status may influence children&#39;s preference for sugar.
