1. Skin color affect the replacement of amalgam for composite in posterior restorations: a birth-cohort study
Abstract The aim of present study was to estimate the occurrence and associated factors for replacement of amalgam posterior restorations. A representative sample of all 5,914 births from the 1982 in Pelotas birth cohort study was prospectively investigated, and the posterior restorations were assessed at 24 (n = 720) and 31 years of age (n = 539). Individua

2. Human exposure to mercury and its hematological effects: a systematic review
O mercúrio é um metal que pode ser encontrado naturalmente no meio ambiente e através de fontes antropogênicas. É altamente tóxico para ecossistemas e seres vivos. A maior parte da exposição humana provém da ingestão de pescados contaminados, da liberação de gases da amálgama dentária ou da exposição ocupacional (p.ex.: extração de ouro). V

3. Time expended on managing molar incisor hypomineralization in a pediatric dental clinic in Nigeria
Abstract This study assessed the difference in the number of visits made to a dental care clinic and the time spent providing specific dental treatment for children with and without molar incisor hypomineralization (MIH). Children aged 8 to 16 years who presented at the Pediatric Dental Unit of the Obafemi Awolowo University Teaching Hospital Complex, in Ile

4. Streptococcus mutans adhesion and releasing of metallic ions in dental alloys
AIM: To evaluate the adherence of Streptococcus mutans to the surface of the amalgam and copper/aluminum alloy samples and also evaluate the release of metallic ions. METHODS: The prepared medium was changed every 72 h and analyzed by atomic absorption spectrophotometer. Samples were removed from the prepared medium at 15, 30, 48 and 60 days. RESULTS: The r

5. Recovering Streptococcus mutans over restorations by the tray technique: a randomized clinical study
AIM: To correlate the tray technique for isolation and counting of Streptococcus mutans over dental restoration with the toothpick technique. METHODS: Forty 18-50-year-old patients of both genders with high cariogenic risk were selected. Inclusion criteria were: occlusal restoration evaluated as alpha, according to the Ryge's criteria (examiner' Cohen-Kappa

6. Microleakage in combined amalgam/composite resin restorations in MOD cavities
AIM: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. METHODS: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of

7. Caracterização clínica-histológica e estudo de polimorfismos das respostas T-Helper-1 e 2 (Th1/2) nas doenças imunologicamente mediadas com manifestações bucais : líquen plano oral e reação liquenóide oral por amálgama dental / Clinical-histological characterization and study of polymorphisms of T-Helper-1 and 2 (Th1 / 2) responses in immune-mediated diseases with oral manifestations : oral lichen planus and amalgam-associate oral lichenoid reaction
As lesões liquenóides orais (LLO), como líquen plano oral (LPO) e reação liquenóide oral por amálgama dental (RLO-AD), são doenças imunologicamente mediadas (DIM) com características histopatológicas semelhantes, porém com prognósticos distintos. As suas etiopatogenias têm sido relacionadas a polimorfismos gênicos e secreção citocinas de inf

8. Impact of the implantation of a new curriculum in the process of learning in a Faculty of Dentistry in Brazil
The aim of the present study was to evaluate two dental curricula at a school of dentistry in southern Brazil. The study population included dentists trained in the last two classes of the institution's old curriculum (n = 98) and graduates of the first two classes of the new curriculum (n = 56). A questionnaire with open and closed questions was used for an

9. Tratamento de lesões profundas de cárie : um ensaio clínico randomizado comparando tratamento expectante com remoção parcial da dentina
This randomized multicenter clinical trial evaluated the effectiveness of an alternative treatment on deep caries lesion¿s compared to stepwise excavation (SW) after three years follow up. Treatment consisted on partial caries removal (PDR) followed by tooth¿s restoration in one session. Methods: Inclusion criteria were: patients with permanent molars pres

10. Recovery of silver residues from dental amalgam
Dental amalgam residues are probably the most important chemical residues generated from clinical dental practice because of the presence of heavy metals among its constituents, mainly mercury and silver. OBJECTIVE: The purpose of this study was to develop an alternative method for the recovery of silver residues from dental amalgam. MATERIAL AND METHODS: Th

11. Validação de metodologia analítica para determinação de mercúrio total em amostras de urina por espectrometria de absorção atômica com geração de vapor frio (CV-AAS): estudo de caso
Mercury is a toxic metal used in a variety of substances over the course history. One of its more dubious uses is in dental amalgam restorations. It is possible to measure very small concentrations of this metal in the urine of exposed subjects by the cold vapor atomic absorption technique. The present work features the validation as an essential tool to con

12. Remoção parcial de tecido cariado em lesões de cárie profundas de dentes permanentes = Partial removal of carious dentine in deep caries lesion in the permanent dentition / Partial removal of carious dentine in deep caries lesion in the permanent dentition
The partial removal of carious dentine was studied by means of a literature review and a multicenter randomized controlled clinical trial. The clinical trial compared the effectiveness of an alternative treatment for deep caries lesions and the stepwise excavation in Public Health Services in Brazil. The treatment consists of partial removal of carious denti
