Dental (silver) amalgam is a widely used restorative material containing 50% elemental mercury that emits small amounts of vapor. No randomized clinical trials have determined whether there are significant health risks associated with this low-level exposure.To assess the safety dental restorations in children.A trial which children requiring treatment were to either for posterior or resin composite instead amalgam. Enrollment commenced February 1997, annual follow-up 7 years concluding July...

ABSTRACT Of the 176 randomly selected, commensal, gram-negative bacteria isolated from healthy children with low exposure to antibiotics, 138 (78%) carried one or more of seven macrolide resistance genes tested in this study. These isolates included 79 (91%) oral cavity and 59 (66%) urine samples. The mef (A) gene, coding for an efflux protein, was found 73 (41%) most frequently gene. gene could be transferred donors into a gram-positive E. faecalis recipient Escherichia coli recipient. erm...

BackgroundUrinary mercury concentrations are widely used as a measure of exposure from dental amalgam fillings. No studies have evaluated the relationship these measures in longitudinal context children.ObjectiveWe urinary children 8–18 years age relation to number surfaces and time since placement over 7-year course treatment.MethodsFive hundred seven children, 8–10 at baseline, participated clinical trial evaluate neurobehavioral effects children. Subjects were randomized either or resin...

Neurological examination of children includes the screening for soft neurological signs (NSS). There is little knowledge about their evolution during adolescence, except that lasting presence has been associated with developmental, psychological, and cognitive disorders. We report results a NSS exam (assessing gross fine motor function hyperactivity impersistence) over 5-year period, among group healthy who were followed annually as part dental study. Their ages ranged from 11 to 15 years at...

A voluntary sample 879 teenagers completed it, mean aged 14.9 (±1.83) years, Romania (n = 455), Portugal 200), 224) as part EuHyDens project. survey took...

This study aimed to assess adolescents' Mental Health Literacy (MHL) level, Positive (PMH) the association between sociodemographic variables and MHL PMH levels, relationship adolescent's levels. A quantitative, cross-sectional, correlational was conducted with a convenience sample of 260 adolescents studying in 5th 12th years school. The Knowledge Questionnaire, Health-Promoting Knowledge, Questionnaire were used for data collection. Most female (55.8%) mean age 14.07 years. participants...

Abstract Cold atmospheric plasma (CAP), as a noninvasive technology, has shown promise in dentistry it might successfully treat various oral conditions. The antimicrobial capacity of CAP been proven and is effective reducing the main microorganisms responsible for infections. Furthermore, also explored field tissue regeneration with great response from both soft hard tissue. surface modification ability another area interest, revealing potential improvement osseointegration dental implants....

Abstract Purpose This prospective clinical study evaluated the success rate of indirect composite resin cuspal coverage on endodontically treated molars and premolars survival restored teeth. Materials Methods One hundred fifty teeth were with total randomly selected for study. Patients recalled after 2 to 5 years evaluation. Data subjected standard tests statistical correlations using Spearman test. Results Out 150 teeth, 84 66 premolars. Of these 58.7% had mesio‐occlusal‐distal (MOD)...

Saliva research has gained interest due to its potential as a source of biomarkers. One the factors inducing changes in saliva, short term, is food intake, and evidence exist about salivary proteome induced by some components. Since this topic early stages, it was hypothesized that saliva protein composition could be associated with different levels adherence dietary patterns contain higher amounts plant products. The aim present study test hypothesis, adults, comparing electrophoretic...

ABSTRACT We screened 615 gram-positive isolates from 150 healthy children for the presence of erm (A), (B), (C), (F), and mef (A) genes. The genes were found in 20 (9%) macrolide-resistant isolates, including Enterococcus spp., Staphylococcus Streptococcus spp. Sixteen 19 tested carried other seven open reading frames (ORFs) described Tn 1207.1 , a genetic element carrying recently pneumoniae . three did not carry orf1 to orf3 A gram-negative Acinetobacter junii isolate also ORFs 1207.1....

The staphylococcal msr(A) gene, coding for a macrolide efflux protein, was identified in three new gram-positive genera and one gram-negative genus. These genes shared 99 to 100% identity with each other the gene. This study demonstrates that gene has wider host range than previously reported.

Background: Oral food perception plays a major role in acceptance, although the way it relates with preferences and final choices adults is still debatable. The objective of present study was to assess relationship between gustatory function, dietary habits fruit vegetable preferences. Methods: Recognition thresholds, suprathreshold hedonics were accessed for sweet, bitter, sour, salty astringency 291 adult participants. A Food Frequency Questionnaire (FFQ) questionnaire assessment...

Abstract Background/aims: Only limited information exists about the prevalence in children of pathogens associated with periodontitis. The aim present study was to determine by culture whether 8–11‐year‐old carry Porphyromonas gingivalis , Prevotella intermedia and/or P. nigrescens samples from gingiva buccal mucosa taken before, and after caries treatment oral hygiene instruction. A second assess proportion subjects who had gram‐negative anaerobes carrying tet (Q) erm (F) genes, suggesting...

To evaluate the respective part of HIV-1, HIV-2 and human T lymphotropic virus (HTLV) infection in Fortaleza, principal city Ceara state (Northeast Brazil), a cross-sectional seroepidemiological survey was conducted from July 1993 to February 1994 6 selected groups: pregnant women, tuberculosis (Tb) patients, sexually transmitted disease (STD) female male commercial sex workers (CSWs) prisoners. Sera were screened by Mixt HIV-1/HIV-2 enzyme immunoassay ELISA HTLV I/II. Each serum found...

Neurological subtle signs (NSS) are often observed during the neurological examination of children and tend to disappear with age. Their persistence into late adolescence or young adulthood has been related psychiatric neurocognitive disorders. To provide a better understanding their functional basis, longitudinal correlational study measurements was performed.We conducted multiple regression correlation analyses NSS demographic cognitive measures on subset 341 healthy (56% males), taking...
