Psychometric Properties of the Portuguese Version of the Quality of Life in Autism Questionnaire (QoLA).

The aim of this study was to cross-culturally adapt and validate of the Brazilian Portuguese version of the Quality of Life in Autism Questionnaire (QoLA) among parents of children ASD. The translated version was administered to 91 parents (Male: 4, Female: 85, other: 2) of individuals diagnosed with ASD. Among these, 22 completed the questionnaire twice, providing data for the assessment of test-retest reliability (ICC). The B-QoLA score ranged from 41 to 122, with a mean (SD) of 74.3 ± 18.5 in Part A and ranged from 22 to 94, with a mean (SD) of 61.6 ± 16.4, in Part B. Cronbach's alpha coefficient was 0.94 for Part A, 0.92 for Part B and 0.94 for total B-QoLA, indicating excellent internal consistency. Test-retest reliability was assessed using the intraclass correlation coefficient, which was 0.96 for the total scale, 0.94 for Part A, and 0.95 for Part B. Part A-X2 (df) = 297, (167), X2/2 = 1.7, CFI = 0.85, TLI = 0.84, GFI = 0.78, AGFI = 0.75, and RMSEA (95%CI) = 0.09 (0.07-0.11); Part B-X2 (df) = 297, (167), X2/2 = 1.7, CFI = 0.85, TLI = 0.84, GFI = 0.78, AGFI = 0.75, and RMSEA (95%CI) = 0.09 (0.07-0.11), thus indicating moderate fit of the model. The Brazilian version of the QoLA shows encouraging psychometric properties on each of the two subscales, showing strong internal consistency and good construct validity.

Relationship among thermal environment, stage of lactation, body characteristics, yield and milk constituents of dairy Gyr cows managed on pasture.

Our aims were to evaluate changes in body characteristics, milk yield and milk constituents as well as to determine the relationship between the thermal environment and production characteristics during the first lactation of dairy Gyr cows managed on pasture. Between 2013 and 2015, forty-five primiparous dairy Gyr cows were evaluated from prepartum to 10 months of lactation in Southeast of Brazil. Body weight, body condition score (BCS), subcutaneous fat thickness (SFT), milk yield (305 d), and milk constituents were collected monthly and progesterone was collected weekly. Additionally, we determined the temperature humidity index (THI) based on microclimate data. Overall, the cows lost body weight until six months of lactation and there was a progressive decrease in BCS, SFT, milk yield and milk lactose as the months in lactation progressed. In contrast, there was an increase in milk fat, milk protein and milk solids. The thermal environment did not pose a consistent heat challenge, nevertheless, we found a positive correlation between the average THI two days before milk collection with milk yield, fat and lactose contents, but in contrast a negative correlation was found with total solids and protein. In conclusion, the THI and months of lactation affected the yield and constituents of milk. However, more studies are necessary to understand the impacts of body characteristics and thermal environment on yield and milk constituents throughout the productive life of Gyr dairy cows.

Resistance to natural tick infestation varies with age and coat and hair traits in a tropically adapted beef cattle breed.

Rhipicephalus (Boophilus) microplus causes considerable livestock production losses. Knowledge of the traits that influence tick resistance contributes to the development of breeding strategies designed to improve herd productivity. Within this context, this study evaluated the resistance of Caracu, a tropically adapted cattle breed, to R. microplus. Tick count, hair length, coat thickness, and coat color were evaluated in 202 naturally tick-infested females (cows and heifers) over a period of 18 months. Blood samples were collected from all animals during the winter season for hematological analysis. Data were analyzed using Pearson correlations, generalized linear models, and principal component analysis. Correlation coefficients of tick count with coat color, coat thickness, and hair length were estimated within each season. Hematological parameters were only included in the winter season analysis and were analyzed by the restricted maximum likelihood method using log-transformed data. No differences in blood parameters were observed between animals with and without ticks. However, tick count was negatively correlated with erythrocytes (-0.29) and hematocrit (-0.24) and positively correlated with mean corpuscular hemoglobin (0.21) and mean corpuscular hemoglobin concentration (0.25). These findings suggest that higher tick counts lead to a decrease in erythrocytes but also to an increase in the amount of hemoglobin per erythrocyte, which could reduce the damage caused by low erythrocyte levels due to tick hematophagy, delaying or preventing anemia. Although tick infestation on pasture was demonstrated by the infestation of all staff members during herd management, none of the animals exhibited high tick counts, providing evidence of resistance of Caracu animals to R. microplus. Tick infestation was influenced by age class (cows > heifers), season (spring and summer > fall and winter), coat thickness (>1.5 mm > <1.5 mm), and hair length (>6 mm > <6 mm). Three components were extracted by principal component analysis, which accounted for 69.46% of data variance. The findings of this study will contribute to the development of efficient strategies aimed at reducing economic losses due to tick infestation and could be applied in animal breeding to select for tick resistance traits, reducing chemical control strategies and consequently improving sustainable livestock production.

Muscle mass evaluation in hospitalized patients: Comparison between doubly indirect methods.

BACKGROUND: Loss of muscle mass (MM) in hospitalized patients has been associated with negative outcomes, thus, evaluating this biomarker is important to stratify risk. Although studies have been showing that calf circumference (CC) and bioelectrical impedance analysis (BIA) are valid for estimating MM in hospitalized patients, we do not know if they are associated. The aim of this study was to evaluate the associations between CC and BIA in hospitalized patients. METHODS: A cross-sectional study, in hospitalized patients' post-acute cardiac event. We collected sociodemographic, clinical, and anthropometric data. CC measurement was adjusted according to the BMI. Spearman's correlations and associations between the methods were performed for the total sample, according to sex and stage of life (older adults or not). RESULTS: We included 177 patients, mean age of 60.5 ± 12.4 years old, the majority males (75 %). Median BMI was 26.2 kg/m2 (23.8-29.2 kg/m2), most of them overweight (41.8 %). The median of CC was lower in females and older adults, and majority of the patients had low CC (87.6 %). Higher values of fat-free mass (FFM) by BIA were observed in males and younger adults, and 5.6 % presented low FFMI. We found a positive and moderate correlation between fat-free mass index (FFMI) and CC (rho = 0.532). Males had higher correlations (rho = 0.481). An increase of 1 kg in the FFM represented an increase of 1.16 cm (crude analysis) to 1.59 cm (adjusted analysis) in CC (p < 0.001). FFM explained 37 % in the variability of CC, and together with BMI, sex and age, explained 60 % in the variability. CONCLUSIONS: Raw values of FFM obtained by BIA and CC presented a weak to moderate correlation in cardiac patients. Changes in one measure impact on the other one.

Relationship between age, scrotal circumference, postweaning weight and semen quality in Nellore and Caracu bulls: a cross sectional study.

The aim of this study was to investigate the relationship between age, scrotal circumference, postweaning weight and semen quality in Nellore and Caracu bulls selected for postweaning weight. Data from the andrological evaluation of 836 bulls born between 2000 and 2019, including 583 Nellore animals (Bos indicus) and 253 Caracu animals (Bos taurus), were used. The bulls were divided into categories of age at the time of assessment: category 1 consisted of animals aged 20 to 23 months (22 ± 0.76 months, 518 ± 94.17 kg), category 2 consisted of animals aged 24 to 35 months (30 ± 4.42 months, 679 ± 137.19 kg), and category 3 consisted of animals ≥ 36 months (60 ± 14.12 months, 907 ± 161.73 kg). The statistical model included the effects of breed, age category, date of semen collection, and breed x age category interaction. Heritability estimates for scrotal circumference at 13 months of age (SC1year) and semen quality traits were obtained for the sample of Nellore animals. Most semen quality traits improved with increasing age in both Nellore and Caracu animals. High heritability was observed for SC1year (0.45), while sperm motility, vigor, turbulence, and major, minor and total sperm defects exhibited low heritability (0.11, 0.019, 0.047, 0.017, 0.017 and 0.019, respectively). Spearman correlations of breeding values for postweaning weight (W378) and SC1year with the semen quality traits were low. Nellore and Caracu bulls have similar semen quality that improves with increasing age. In the Nellore breed, the heritability of SC is high, while semen quality traits exhibit low heritability. Selection for higher postweaning weight does not phenotypically affect the semen quality of bulls at breeding age.

Responsiveness of the B-ECOHIS to detect changes in OHRQoL following dental treatment of children with autism spectrum disorder.

The Brazilian Early Childhood Oral Health Impact Scale (B-ECOHIS) is an oral health-related quality of life (OHRQoL) questionnaire. This paper aims to investigate the responsiveness of the B-ECOHIS to dental treatment in individuals diagnosed with autism spectrum disorder (ASD) and determine if dental treatment has an impact on OHRQoL. The survey targeted 27 ASD individuals aged 4 to 14 years attending the Acolher Project of the University Federal Fluminense. This project provides children and adolescents with disabilities with oral health services. A group of randomly selected caregivers self-completed the B-ECOHIS before and 14 days after their children's dental treatment. The dental treatment included meticulous screening, preventive treatment, and restorative treatment. Responsiveness was assessed by investigating the effect size (ES) and standardized response mean (SRM). Wilcoxon test was used to evaluate internal responsiveness (distribution-based approach). The B-ECOHIS showed significant changes in the total score (p<0.001) and in all domains. The ES of the total B-ECOHIS after treatment was 1.28 and ranged between 0.70 and 1.14 for the domains. The SRM for each of the domains was large, except for the symptom domain. The B-ECOHIS is sensitive and responsive to ASD individuals undergoing dental treatment. Individuals with ASD showed improvement in their OHRQoL score after dental treatment.

Incorporation of a polymerization catalyst for improved mechanical behavior and physicochemical characteristics of a light-cured pulp capping material / Incorporação de um catalisador de polimerização para aprimorar propriedades mecânicas e fisíco-químicas de um protetor pulpar fotoativável

Objective: To evaluate the influence of the incorporation of a polymerization catalyst to a light-cured pulp capping material on mechanical behavior and physicochemical characteristics. Material and Methods: Different percentages (2 wt%, and 4 wt%) of diphenyliodonium hexafluorophosphate (DPI) were incorporated into the Ultra-Blend Plus, a resin-modified calcium-based cement. The material without incorporation of DPI (0 wt%) served as control. Degree of Conversion (DC), Flexural Strength (FS), Elastic Modulus (EM), Water Sorption (WSp), Solubility (Sl), and pH of eluate at 24-h, 72-h, and 7-day storage times were measured. One-way ANOVA/Tukey posthoc tests were used to analyze the data (p <0.05). Results: For DC, FS, and EM, materials with different % of DPI showed statistically significant differences, so that 0% provided the lowest values and 2% the highest values. Materials with 0% and 2% of DPI provided statistically the lowest WSp, whilst material with 0% of DPI showed statistically the highest Sl. Conclusion: All materials provided statistically similar pH to eluates regardless of storage time, although only materials with DPI at 2% and 4% maintained pH of eluates statistically similar from 72 h to 7 days storage times.(AU)

SARS-CoV-2 DNA Vaccine INO-4800 Induces Durable Immune Responses Capable of Being Boosted in a Phase 1 Open-Label Trial

BackgroundAdditional SARS-CoV-2 vaccines that are safe and effective as primary vaccines and boosters remain urgently needed to combat the COVID-19 pandemic. We describe the safety and durability of the immune responses following two primary doses and a homologous booster dose of an investigational DNA vaccine (INO-4800) targeting the full-length spike antigen. MethodsThree dosage strengths of INO-4800 (0.5 mg, 1.0 mg, and 2.0 mg) were evaluated in 120 age-stratified healthy adults. Intradermal injection of INO-4800 followed by electroporation at 0 and 4 weeks preceded an optional booster 6-10.5 months after the second dose. ResultsINO-4800 appeared well tolerated, with no treatment-related serious adverse events. Most adverse events were mild and did not increase in frequency with age and subsequent dosing. A durable antibody response was observed 6 months following the second dose; a homologous booster dose significantly increased immune responses. Cytokine producing T cells and activated CD8+ T cells with lytic potential were significantly increased in the 2.0 mg dose group. ConclusionINO-4800 was well tolerated in a 2-dose primary series and as a homologous booster in all adults, including the elderly. These results support further development of INO-4800 for use as a primary vaccine and as a booster. Trial Registration: ClinicalTrials.gov NCT04336410 SummaryTwo-milligram dose of INO-4800, a DNA-based vaccine encoding the SARS-CoV-2 spike protein, appears safe and well-tolerated and elicits humoral and cell-mediated immunity persisting to 6 months after a second dose. A third dose 6-10.5 months later significantly boosts immune responses.

Mirror image: an unusual case of prolonged tooth retention in twins

Introduction: Studies of twins are important because environmental and genetic factors seem to be related to the phenotypic alterations. Objective: This paper presents a unique case of monozygotic twins with mirror image of a retained primary central incisor. Case report: Twin male brothers, 9-years-old, presented prolonged retention of the primary central upper incisor. The over-retained teeth in one twin were a mirror image of those in the other twin. The first twin presented a prolonged retention of the tooth 51 whereas the other twin presented a prolonged retention of tooth 61. After radiographic exams the over-retained teeth were extracted. Conclusion: Twins may show similarity in pattern of dental anomalies supporting the influence of genetic factors. In identical twins the location of diagnosed anomalies can be mirror imaged. This fact should lead the professional to examine the pair of twins in order to diagnose any dental anomaly that may be present.

Introdução: Estudos feitos em gêmeos são importantes porque fatores ambientais e genéticos parecem estar relacionados às alterações fenotípicas. Objetivo: Este artigo apresenta um caso raro de gêmeos monozigóticos apresentando imagem em espelho de retenção prolongada de incisivos centrais decíduos superiores homólogos. Relato do caso: Os irmãos gêmeos, com 9 anos de idade, não apresentavam história de trauma orofacial ou doença comum da infância. Após exames clínicos e radiográficos foram identificados a retenção do dente 51 no gêmeo 1 e do dente 61 no gêmeo 2. Em ambos os pacientes, os dentes 11 e o 21 estavam em erupção. O tratamento proposto foi a exodontia dos dentes decíduos com anestesia local e acompanhamento. Conclusão: Gêmeos podem apresentar semelhança no padrão de anomalias dentárias devido à influência de fatores genéticos. Adicionalmente, em gêmeos monozigóticos, a localização das anomalias diagnosticadas pode se apresentar invertidas ou imagem em espelho. Esse fato deve estimular o profissional a examinar o par de gêmeos para diagnosticar qualquer anomalia dentária que possa estar presente. O diagnóstico precoce e tratamento adequados devem ser realizados para evitar danos funcionais e estéticos em pacientes com retenções dentárias.

Impact of untreated dental caries on oral health-related quality of life of children with special health care needs.

The oral health status of children with special health care needs (SHCN) can affect their quality of life wich domains of the Brazilian version of the Early Childohood Oral Health Impact Scale (B-ECOHIS). A cross-sectional study was conducted in children with SHCN (aged 1 to 9 years), who underwent an oral examination for the assessment of dental caries severity. Parents/caregivers answered two questionnaires, one on oral health-related quality of life (OHRQoL) - B-ECOHIS, and one on socioeconomic characteristics. Statistical analyses were performed using the Kolmogorov-Smirnov test, Mann-Whitney U-test, Poisson regression, Point-biserial correlation coefficient, and Cronbach's alpha. A total of 128 children participated in the study and OHRQoL was affected in 68.75% of them. The function domain in the Child Impact Section (CIS) had a higher mean value. Caries severity was associated with worse quality of life (p=0.001). Severe dental caries was associated with a negative impact on the OHRQoL of disabled children and of their families. The impact of untreated dental caries and severity of dental caries was associated with the CIS domains (except for the self-image/social interaction domain).

Oral conditions of pediatric patients with Williams-Beuren syndrome: two case reports / Condição Oral de paciente infantil com Síndrome de Williams-Beuren: dois casos clínicos

Objective: The objective of this paper was to describe the oral conditions of two children accompanied by their mothers who reported to the Department of Pediatric Dentistry of Fluminense Federal University with Williams-Beuren syndrome (WBS). Case report: The 9-year-old female patient had a family and medical history significant for placental abruption, caesarean section, delayed psychomotor development, learning disabilities, tendency to selfdistract and congenital heart disease. In contrast, the 7-year-old male patient had a normal birth and no gestational intercurrences. Discussion: Clinically, the female presented with mixed dentition, crowding in the maxillary and mandibular arches, prolonged retention of deciduous teeth, anterior and posterior cross-bite and Angle Class I malocclusion, while the male had mixed dentition and retarded psychomotor development. Due to the patients having congenital heart disease, a prophylactic antibiotic regimen was prescribed prior to the dental procedures in both of them. Conclusion: These patients had been followed up for 2 years and this case report underscores the importance of early dental evaluation and counselling for parents of WBS patients (AU)

Influence of Two Types of Connections in Driver-Retention Screw Assembly.

Rehabilitation with implant-supported prostheses has reached high success rates. However, mechanical failures are still reported, mainly in retention screws of abutments in single implant-supported crowns; which is designed to be the weakest structure and the first component to fail under overloading. In this sense, the aim of this in vitro study was to evaluate the influence of different joint designs (square or hexagonal) on resistance to deformation of driver-retention screw assembly of 3 commercial brands (Neodent, Singular, and Sin). A total of 42 retention screws from 3 commercial brands were used. The samples were divided into 2 joint groups, square (SQU) and hexagonal (HEX), and separated by commercial brands. Several components (implants and abutments) with standard platform (4.1 mm in diameter) were used. The resistance to deformation of the driver-retention screw assembly was measured using an accurate digital torque wrench for all commercial brands (Neodent [NEO], Singular [SGL], and Sin [SIN]) and joint designs (square or hexagonal). It was found no statistically significant difference (P <0.05) among the brands evaluated. On the other hand, square screws showed higher resistance to torsion than hexagonal screws; regardless the commercial brand.

Influência do tipo de conexão (quadrado ou hexagonal) na resistência a deformação do conjunto chave-parafuso de retenção de prótese sobre o implante / Influence of joint design (square or hexagonal) on resistance to deformation of driver-screw retention assembly on implant-supported prosthesis

O tratamento reabilitador com próteses implantossuportadas tem alcançado elevados índices de sucesso. No entanto, falhas mecânicas ainda podem ocorrer, especialmente, nos parafusos de retenção dos pilares protéticos de restaurações unitárias sobre implante, sendo esses desenhados para ser o elo mais fraco na estrutura e ser o primeiro elemento a falhar em situações de sobrecarga. Nesse contexto, o objetivo deste trabalho foi avaliar in vitro a influência de diferentes tipos de conexões (quadrado ou hexagonal) na resistência à deformação do conjunto chave-parafuso de retenção de três diferentes marcas comercias (Neodent, Singular e Sin). Foram utilizados quarenta e dois (42) parafusos de retenção, de três (3) diferentes marcas comerciais. Esses foram divididos em dois grandes grupos de conexão, quadrada (QUA) e hexagonal (HEX) e separados por marcas comerciais. Foram utilizados vários componentes (implantes e pilares protéticos) que apresentavam plataforma regular padrão (4.1 mm de diâmetro). Para medir a força da resistência à deformação do conjunto chave- -parafuso de retenção, utilizou-se um torquímetro digital de alta precisão, para cada uma das três (3) diferentes marcas comerciais - Neodent (NEO), Singular (SGL) e Sin (SIN) - variando a geometria do sistema de conexão (quadrado ou hexagonal). Observou-se ausência de diferença estatisticamente significante (p<0,05) entre as três marcas comerciais analisadas. Por outro lado, independente da marca comercial, dentre os parafusos examinados, os parafusos quadrados apresentaram maior resistência à torção do que os parafusos hexagonais (AU).

Metal free: avaliação do tipo de material restaurador e forma de comunicação dentista-laboratório em reabilitações estéticas com prótese fixa em Natal/RN / Metal free: evaluation of restorativematerials and dentist-laboratory communication in aesthetic rehabilitation using fixed prosthesis in Natal/RN (Brazil)

Atualmente, a busca pela estética perfeita está diretamente aliada à qualidade de vida das pessoas. Por conta do grande avanço de estudos das propriedades dos materiais odontológicos, as restaurações de cerâmica pura estão sendo cada vez mais procuradas por proporcionarem estética e longevidade. Levando em consideração o conhecimento das etapas clínicas e do material utilizado por parte do cirurgião-dentista e sua relação com o protético, que tem uma direta ligação com o sucesso dos trabalhos reabilitadores em prótese fixa, o objetivo desse estudo é avaliar o tipo de material restaurador e forma de comunicação dentista-laboratório em reabilitações estéticas com prótese fixa em Natal/RN. Foram entrevistados 12 laboratórios devidamente registrados no CRO-RN, onde apenas 30% trabalham com cerâmica pura, 86% utilizam E-max na região anterior, e na região posterior 100% utilizam E-max, Noretack e Inceram. Com relação à comunicação com os laboratórios, 75% dos dentistas especificam o tipo de material cerâmico a ser utilizado na confecção da restauração, principalmente através da escrita. 58,3% dos dentistas selecionam o tipo de material, onde 51,42% selecionam a cor através da escrita. Apenas 41,67% dos dentistas informam a cor do substrato e desses 50% o fazem através de fotografia. Em relação ao envio, 75% dos dentistas encaminham o trabalho ainda em molde, onde 37% utilizam silicona de adição como material de moldagem. Concluiu-se que os sistemas cerâmicos em Natal-RN ainda são pouco utilizados e a comunicação dentista-laboratório deve melhorar para que o sucesso desse tipo de reabilitação seja obtido e cada vez mais difundido entre os profissionais.

Preferência por estilos de filmes e suas diferenças nos cinco fatores de personalidade / Preference for movie styles and their differences in the five factors of personality / Preferencia por géneros cinematográficos y sus diferencias en los cinco factores de personalidad

Podemos conceber que a preferência por mídias está em consonância com nossos traços de personalidade, mas muitos estudos são necessários para se avançar nesta área. Objetivou-se verificar se existem diferenças nos cinco fatores de personalidade em grupos de preferência por filmes, bem como testar uma breve medida de personalidade. Foram realizados dois estudos com estudantes do ensino médio e universitário com o Inventário de Personalidade de Dez Itens (TIPI). Os resultados mostraram mais Agradabilidade nos estudantes que relataram preferência por filmes de terror em comparação àqueles que preferiram suspense. Os que preferiram filmes de suspense mostraram menor Conscienciosidade em comparação aos que preferiam terror, ação, romance e drama. Os que preferiram filme romântico, em comparação àqueles que preferiram comédia, apresentaram mais Conscienciosidade. Tais resultados se mantêm, controlando-se o sexo e a idade. Conclui-se que o TIPI é uma medida que pode ser usada em pesquisas para entender diferenças de grupos nos cinco fatores de personalidade.

Theoretically, our media preference is in line with our personality traits, but many studies are needed to advance in this area. The objective of this study was to determine whether there are differences in the five personality factors in groups with a movie preference as well as to test a brief personality inventory. Two studies were conducted with high school and university students, using the Ten-Item Personality Inventory (TIPI). The results showed more Agreeableness for those students who reported a preference for horror movies than for those who prefer suspense. Those who prefer suspense showed less Conscientiousness than those who prefer horror, action, romance and drama. Those who preferred romantic movies, when compared to those who prefer comedies, presented more Conscientiousness. These results are maintained by controlling the sex and the age. We conclude that the TIPI is a measure that can be used in research to understand group differences in the five personality factors.

Teoricamente, elegimos los medios de comunicación en línea con los rasgos de personalidad, pero estudios son necesarios para avanzar en este ámbito. El objetivo fue determinar sí existen diferencias en los cinco factores de personalidad en grupos de preferencia para las películas, com un breve test para medir la personalidad. Dos estudios se llevaron a cabo con estudiantes de secundaria y universitarios con el Inventario de Personalidad de Diez Ítems (TIPI). Los resultados mostraron que los con altos puntajes en Amabilidad informarón preferencia por las películas de terror en comparación a los estudiantes que prefieren el suspense. Los que prefieren suspense mostraron medias más altas en Responsabilidad en relación a los que prefieren horror, acción, romance y drama. Los que preferían película romántica, en comparación con aquellos que prefieren comedia, presentarón más Responsabilidad. Estos resultados se mantienen al controlar el sexo y la edad. Se concluye que el TIPI es una medida que puede ser utilizado en la investigación para entender las diferencias de grupo en los cinco factores de personalidad.

Clinical signs and bacterial communities of deciduous necrotic root canals detected by PCR-DGGE analysis: research association.

OBJECTIVE: This study sought to investigate the possible association between clinical and radiographic data of the patients with the bacterial community profiles involved in cases of necrosis in primary root canals. METHODS: Microbial community profiles for 25 samples from necrotic deciduous root canals were analyzed using the polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) fingerprinting approach. These results were related to the clinical and radiographic data of these patients. RESULTS: The analysis showed a large diversity of microbial communities in necrotic deciduous root canals. The statistical results pointed out that posterior and anterior teeth were associated with <20 bands and >20 bands in PCR-DGGE method, respectively. A relationship was verified between ages >4 years old and posterior teeth and, ages ≤4 years old and anterior teeth. CONCLUSIONS: The data showed a polymicrobial community and pointed out the association of age with necrosis in anterior and posterior teeth.
