1. Determination of Boron Isotope Ratios in Tooth Enamel by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) After Matrix Separation by Ion Exchange Chromatography
Boron isotopes in teeth has been a new proxy for dietary reconstructions and its resistance to diagenetic alteration. In this study a method using inductively coupled plasma source mass spectrometry (ICP-MS) for the measurement of boron isotope ratio in human dental enamel has been developed. Human dental enamel were digested with HNO3-H2O2 in a microwave sy

2. Estimativa da idade cronológica por meio de avaliação radiográfica da mineralização de terceiros molares e altura do ramo da mandíbula / Age determination by means of radiographic evaluation of third molar mineralization and height of the mandibular ramus
A estimativa da idade é um elemento importante na investigação antropológica, sendo uma das fontes preliminares dos dados para estabelecer a identidade de pessoas vivas ou restos mortais desconhecidos. Os métodos mais utilizados para este fim são os baseados no desenvolvimento ósseo e dentário dos indivíduos. Neste sentido, o presente trabalho apres

3. AnÃlise dos procedimentos de estimativa da idade cronolÃgica do indivÃduo pela avaliaÃÃo dentÃria no instituto mÃdico legal de Fortaleza / Analysis of procedures for estimation of chronological age by dental evaluation in the institute of legal medicine of Fortaleza - CearÃ.
The estimation of chronological age can be defined as the process that evaluates the stage of evolution or involution of a body. The age determination by a dental evaluation is a technical inspection that can be performed by a Surgeon-Dentist, in accordance with the law of dentistry practice. This examination is carried through in legal medicine institutes w

4. The use of infrared thermographic imaging for pulp vitality evaluation in vivo / Ensaio sobre o uso da termografia infravermelha na avaliação da vitalidade pulpar in vivo
Nowadays, it is known that the determination of the pulp vitality testing only its nerve sensorial response through thermal or electrical tests is discussable because those procedures are not sufficiently sensitive to determine the degree of pulp involvement. Besides the vitality of the pulp does not only depend on its nerve condition, but on its blood suppl

5. Conditions of mouth status and oral cancer in smokers / Condições orais e câncer de boca em fumantes
The aim of this study was to assess the hypothesis that conditions of mouth status (the use of dentures, recurrent sores by ill-fitting dentures or ill-positioned or broken teeth, frequent intake of hot beverages and irregular or infrequent tooth brushing) may interact with tobacco, alcohol, diet and socioeconomic status in the carcinogenesis of oral cancer.

6. Association among early childhood caries, microbiological composition of dental biofilm, diet, oral hygiene and socioeconomic factors in preschoolers aging 36 to 48 months / Associação entre carie precoce da infancia, composição microbiologica do filme dentario, dieta, higiene bucal e fatores socio-economicos em pre-escolares de 36 a 48 meses
The prevalence of early childhood caries (ECC) in Brazil is high and its severity increases with age. This way, sensitive methods for the early caries diagnosis and risk indicators identification are important for the disease control. This thesis, comprised by three manuscripts, aimed: (1) to undertake a systematic review of studies which have evidenced the

7. A CAMADA DE GORDURA DAS TONINHAS, PONTOPORIA BLAINVILLEI (MAMMALIA, CETACEA) NO LITORAL SUL DO RS: VARIAÇÃO NA ESPESSURA E NA COMPOSIÇÃO DE ÁCIDOS GRAXOS EM RESPOSTA A FATORES AMBIENTAIS E FISIOLÓGICOS.
In order to investigate the usefullness of blubber thickness to estimate the body fat condition in Pontoporia blainvillei, axillary girth measurements were taken from dorsal, ventral and lateral regions, between the pectoral flipper and the dorsal fin. Blubber measurements were obtained for 116 franciscana dolphins, accidentally caught by the coastal artisan

8. Maturação das vértebras cervicais e desenvolvimento dentário em indivíduos de oito a quinze anos de idade.
Este estudo se propôs a avaliar a correlação entre os estágios de maturação das vértebras cervicais (C2, C3 e C4), de acordo com o método proposto por Lamparski (1972), modificado por Hassel e Farman (1995), e os estágios de desenvolvimento das unidades dentárias 43 e 47, segundo a classificação de Nolla (1960), considerando sexo e idade cronoló

9. DNA sequences from multiple amplifications reveal artifacts induced by cytosine deamination in ancient DNA
We show that DNA molecules amplified by PCR from DNA extracted from animal bones and teeth that vary in age between 25 000 and over 50 000 years carry C→T and G→A substitutions. These substitutions can reach high proportions among the molecules amplified and are due to the occurrence of modified deoxycytidine residues in the template DNA. If the template
