1. Production and characterization of colored feldspathic enamel for dental application

In this work we synthesized pigments capable of developing dental shades when mixed with dental porcelain and fired at appropriate temperatures. TiO2-xCeO2 pigments (x = 2, 6, 10, 13 and 18 mol%) were synthesized by the Pechini method. Characterization by thermal analysis revealed the stability of the material at temperatures up to 1200 ºC. X-ray diffractio

2. The combined use of Er,Cr:YSGG laser and fluoride to prevent root dentin demineralization

The use of erbium lasers to prevent caries in enamel has shown positive results. However, it is not known if Er,Cr:YSGG laser can also be used to increase acid resistance of root dentine, which is another dental tissue susceptible to the action of cariogenic bacteria. Objective: To analyze the effects of the Er,Cr:YSGG laser (λ=2.78 μm, 20 Hz) irradiation

3. Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups

Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface. Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections. This

4. Prediction factors for failure to seek treatment following traumatic dental injuries to primary teeth

The objective of this study was to evaluate prediction factors for failure to seek treatment following a traumatic dental injury (TDI) to primary teeth among preschool children in the city of Campina Grande, Brazil. A cross-sectional study was carried out involving 277 children 3 to 5 years of age, with TDI, enrolled in public and private preschools. Parents

5. Enamel crystals of mice susceptible or resistant to dental fluorosis: an AFM study

Objective: This study aimed to assess the overall apatite crystals profile in the enamel matrix of mice susceptible (A/J strain) or resistant (129P3/J strain) to dental fluorosis through analyses by atomic force microscopy (AFM). Material and Methods: Samples from the enamel matrix in the early stages of secretion and maturation were obtained from the inc

6. Dental anomalies in children submitted to antineoplastic therapy

Cancer is the third most frequent cause of death in children in Brazil. Early diagnosis and medical advances have significantly improved treatment outcomes, which has resulted in higher survival rates and the management of late side effects has become increasingly important in caring for these patients. Dental abnormalities are commonly observed as late effe

7. Evaluation of shear bond strength of orthodontic brackets bonded on the tooth surface after internal bleaching

Introdução : O apelo estético de pacientes que possuem dentes escurecidos é grande, pois atualmente os padrões estéticos se tornaram rigorosos e muitos pacientes antes ou durante o tratamento ortodôntico, realizam o procedimento de clareamento dental. Objetivo: Avaliar a adesão de braquetes ortodônticos em molares humanos que receberam claream

8. Avaliação comparativa da ultraestrutura e propriedades físicas do esmalte bovino, bubalino e humano

Este estudo teve como finalidade comparar a morfologia e propriedades físicas da estrutura do esmalte dos dentes bovinos, bubalinos e humanos. A análise deste tecido foi realizada por meio de microscopia eletrônica de varredura, composição mineral, microdureza e rugosidade superficial do esmalte em 41 incisivos bubalinos (Bos taurus indicus), 41 incisiv

9. Dental manifestations of patient with Vitamin D-resistant rickets

Patients with Vitamin D-resistant rickets have abnormal tooth morphology such as thin globular dentin and enlarged pulp horns that extend into the dentino-enamel junction. Invasion of the pulp by microorganisms and toxins is inevitable. The increased fibrotic content of the pulp, together with a reduced number of odontoblasts, decreases the response to pulp
