25. Busca de variações nos genes MSX-1 : relação com a hipodontia / Search of variations in genes MSX-1: relation with the hipodontia
CHAPER I: Through a review of the literature, this article discusses the genetic mechanisms that control tooth morphogenesis. Emphasis is placed upon the structure and function of some key molecules that participate in interactions between its epithelial-mesenchimal components. In this paper we will can understand the mechanisms that control tooth morphogene

26. Análise da associação dos polimorfismos IL1B (C+3954T) e IL1RN (intron 2) com a perda de implantes dentais osseointegráveis
Dental implants have become an important therapeutical modality for tooth replacement. Although the high success rate showed in longitudinal studies, failures occur, even in patients who present appropriate clinical conditions. Together with the clusterization phenomenon, which is the presence of multiple implant losses in the same group of individuals, this

27. "A influência do meio aquático nos processos de identificação humana : estudo epidemiológico e laboratorial (recuperação do DNA )" / The aquatic environment influence in the human identification process: epidemiologic and laboratory study (DNA) recuperation
Os recursos empregados para identificação humana variam desde antropologia física até o estudo dos ácidos nucléicos. Exemplos recentes como o Tsunami, na Tailândia e o Katrina, em Nova Orleans reforçam a necessidade de domínio de técnicas de extração do DNA no processo de identificação de corpos esqueletizados ou em estado de decomposição ava

28. Estudo longitudinal das vias potenciais de transmissão de Streptococcus mutans durante a colonização inicial de bebes de creches publicas da cidade de Piracicaba (São Paulo) / Longitudinal study of potential sources of transmission of Streptococcus mutans during the initial colonization of children from public nurseries in Piracicaba (São Paulo)
Children are more likely to acquire Streptococcus mutans in the oral cavity during the early years of their lives. The mothers are often the main source of S. mutans transmission. This study aimed to identify non-mother potential sources of S. mutans transmission in a population of nursery children during the period of initial colonization, using arbitrarily

29. Influence of sucrose on genotypic diversity of S. mutans in dental biofilm detected by AP-PCR, in situ and in vivo study / Influencia da sacarose na diversidade genotipica de S. mutans no biofilme dental detectados por AP-PCR : estudo "in situ" e "in vivo"
selecting acid-tolerant microorganisms. However, little is known about the influence of sucrose on genotypic diversity of Streptococcus mutans. The aim of this crossover study was to evaluate S. mutans genotypic diversity found in dental biofilm formed in vivo and in situ in the presence of sucrose and glucose+fructose. Seven days before the beginning of the

30. Comparação entre teste bana e checkerboard dna-dna hybridization no diagnóstico periodontal inicial e no monitoramento terapêutico
The aim of this study was tom compare the results of the BANA with the presence of the red complex microorganisms established by the Checkerboard DNA-DNA hybridization in the initial diagnosis and in the therapeutic maintenance of subjects with periodontitis. 54 subjects with chronic periodontitis with at least 15 teeth were selected. Subgingival plaque samp

31. Rastreamento de mutações nos genes PITX2, FOXC1 e GJA1 em pacientes com sindrome de Axenfeld-Rieger associada a glaucoma
Axenfeld-Rieger Syndrome (ARS) is arare disorder, usually transmitted in an autosomal dominant pattem characterized by anterior segment dysgenesis and often associated with developmental glaucoma. In addition to the ocular changes observed in ARS, syndromic features can also occur, such as facial bone defects, teeth anomalies and peri-umbilical skin involuti

32. DNA extraction of human teeth submitted to high temperatures: evaluation of three methods . / "Avaliação de três métodos de extração de DNA de dentes humanos submetidos ao calor"
Biological remains of carbonized human bodies are usually not possible to use in forensic analysis. In these cases, teeth are usually selected since enamel, dentin and cement provides protection to the genetic material. The present study evaluates DNA extracted using three methods (organic, isopropilic alcohol and silica) of teeth submitted to different temp

33. Evaluation of Genotoxic Potential of Formocresol, used compound in the Odontology Practice / Estimativa do potencial genotóxico do formocresol utilizado na prática odontológica
In odontology practice, many drugs used have different purposes, such as primary teeth pulp covers. The Formocresol is the medicine most used in pulpotomy of primary teeth in 1:5 dilution of Buckleys formulation. The clinical safety of Formocresol has been questioned since its formulation is composed by formaldehyde, which is known as a toxic and carcinogeni

34. Investigation of promoter region polymorphisms in the LEF 1 gene in individuals with hypodontia / Investigação de polimorfismos na região promotora do gene LEF 1 em individuos com agenesia dental
Numerous tenns have been used to describe congenital missing teeth. Hypodontia denotes congenital absence of one or a few teeth in the primary and/or permanent dentition. Agenesis of numerous teeth, commonly associated with specific syndromes and/or severe systemic abnornalities is classified as oligodontia. Anodontia, an extreme expression of oligodontia in

35. Influencia de polimorfismos em genes de citocinas na morbidade da doença periodontal inflamatoria cronica
Chronic Periodontal Disease (CPD) is characterized by an inflammation in the supporting tissues of the teeth. It is primarily caused by bacteria present on tooth surfaces (biofilm), which adjacent to the gingiva, stimulate host cells to produce immunoinflammatory response. Cytokines represent important pathological mediators, which influence the onset and pr

36. Detection of 400-year-old Yersinia pestis DNA in human dental pulp: An approach to the diagnosis of ancient septicemia
Ancient septicemic plague epidemics were reported to have killed millions of people for 2 millenniums. However, confident diagnosis of ancient septicemia solely on the basis of historical clinical observations is not possible. The lack of suitable infected material has prevented direct demonstration of ancient septicemia; thus, the history of most infections
