The purpose of this study was to test the null hypothesis that re-expansion dried matrix and shrinkage moist, demineralized dentin is not influenced by polar solvents. Dentin disks were prepared from midcoronal extracted human third molars. After complete demineralization in 0.5M EDTA (pH 7), specimens placed well a device measures changes height real time. Dry, collapsed matrices created blowing dry N(2) on until they shrank stable plateau. Polar solvents [water, methanol, ethanol,...

Laminate veneers are a conservative treatment of unaesthetic anterior teeth. The continued development dental ceramics offers clinicians many options for creating highly aesthetic and functional porcelain veneers. This evolution materials, ceramics, adhesive systems permits improvement the smile self-esteem patient. Clinicians should understand latest ceramic materials in order to be able recommend them their applications techniques, ensure success clinical case. current literature was...

Abstract Purpose To assess in situ the enamel mineralization level and susceptibility to coffee staining after in‐office bleaching. Materials Methods Thirty‐six human dental fragments assembled into intraoral devices were bleached with 35% hydrogen peroxide treated as follows: (group 1) no contact coffee; 2) immersion a solution for 30 minutes daily 7 days, starting 1 week bleaching; 3) 14 immediately Enamel color assessed before bleaching ( T 1), 2), days 4). The CIE whiteness index W *)...

Objectives: This study evaluated the influence of different exposure times to saliva in situ comparison with an antioxidant treatment on composite resin bond strength human enamel restored after tooth bleaching. Material and Methods: Forty teeth specimens measuring 5x5 mm were prepared randomly allocated into 5 groups 8 each: Gct (control group, unbleached enamel); Gbl (restored immediately bleaching); Gsa (bleached, treated 10% sodium ascorbate gel for 60 min restored); G7d exposed 7 days...

Photodynamic therapy has been considered a potential antimicrobial modality against oral infections, including dental caries. A model to estimate the penetration of both photosensitizers and light through human dentin, factor interest in photodynamic therapy, is proposed. The photoacoustic spectroscopy technique was used evaluate vitro dentin permeability three different photosensitizers. Using optical absorption scattering coefficients, it possible propose semi-quantitative predicting...

Current Brazilian law regarding water fluoridation classification is dichotomous with respect to the risks of and benefits for oral diseases, fluoride (F) concentrations less than 0.6 or above 0.8 mg F/L are considered outside normal limits. Thus, does not consider that both caries fluorosis dependent on dosage duration exposure because they chronic diseases. Therefore, this study evaluated quality in Maringá, PR, Brazil, considering a new concentration F supply, based anticaries benefit...

This study evaluated the effect of antimicrobial photodynamic therapy (aPDT) on S. mutans using diacetylcurcumin (DAC) and verified DAC toxicity. In vitro, biofilms were exposed to curcumin (CUR) light-irradiated. Biofilms collected, plated incubated for colony counts. CUR toxicity assays conducted with Human Gingival Fibroblast cells (HGF). vivo, G. mellonella larvae injected treated DAC, aPDT. The hemolymph was Significant reductions observed when alone used aPDT applied. HGF demonstrated...

Composite resin is versatile material for performing several dental procedures in dentistry, and its use has already been consolidated this field. The clinical success of adhesive restorations directly related to the knowledge restorative properties light-curing unit factors, among others. aim study was assess about technical characteristics devices forms maintenance employed by undergraduate students. A total 230 students answered a questionnaire containing six questions on data, use,...

Prevention and health promotion are considered important strategies to control oral diseases. Dental caries is preventable disease remains the most common chronic that affects mainly low income children still main cause of tooth loss in adulthood Brazil.

O objetivo do estudo foi avaliar a aceitação da utilização de metodologias ativas ensino-aprendizagem nos estágios no SUS (Sistema Único Saúde) por discentes graduação e pós-graduação em Odontologia. Foi realizada uma pesquisa opinião, com análise dados forma quanti-qualitativa. Para tanto, 30 estudantes 10 responderam um questionário semiestruturado contendo perguntas relativas às suas experiências esta metodologia. Os revelaram que 67% dos 70% nunca haviam entrado contato...

A clínica ampliada (CA) representa uma estratégia da Política Nacional de Humanização (PNH) para reflexão sobre o cuidado com usuário do Sistema Único Saúde (SUS). Impulsionados pelo Programa Pró-Saúde e pela PNH, docentes curso Odontologia UEM promoveram reestruturação atendimento clínico ofertado, resultando na implantação CA. Este trabalho relata a experiência vivenciada dessa clínica, que visa promover interação vínculo aluno comunidade equipe multiprofissional saúde, modo obter integral...

Abstract Introduction Energy drinks (ED) possess low pH and citric acid in their composition, making them potentially erosive beverages that can contribute to the high dental erosion rates found currently general population also young people. Objective To evaluate mean titratable acidity of commercial ED influence a brand on superficial microhardness human enamel. Material method Ten were selected two lots each with without gas was obtained. Acid titration conducted addition NaOH aliquots...

The mandibular condylar surface is made up of four layers, i.e., an external layer composed dense connective tissue, followed by a undifferentiated cells, hyaline cartilage and bone. Few studies have demonstrated the behavior when mandible positioned posteriorly, as in treatments for correcting functional Class III malocclusion.The aim this study was to assess morphologic histological aspects rat condyles response posterior positioning mandible.Thirty five-week-old male Wistar rats were...

Most supernumerary teeth are impacted and asymptomatic. Objective. The aim of this paper is to describe two cases sequential development in the mandibular premolar region, identified during orthodontic treatment. Reports. first case describes radiographic follow-up a female patient that presented tooth at age 9 years 10 months right followed by further left region 11 3 months. In second case, male demonstrated 16 years. During orthognathic surgery planning 20 5 months, supplemental was found...

The aim of this study was to investigate the aesthetic results orthodontic treatment in Class II individuals. Seven Caucasian females were randomly selected, subjected corrective with extraction at least two pre-molars and initiation between 16 26 years age. All patients interviewed; their speeches recorded then transcribed analyzed. Plaster models, lateral radiographs photographs contained records consulted assess five quantitative parameters: facial contour, nasolabial angle, incisors...
