1. Diversity of clinical, radiographic and genealogical findings in 41 families with amelogenesis imperfecta
Abstract Amelogenesis imperfecta (AI) is a group of enamel development disorders that alter the structure and chemical composition of the tissue. There is great variability in the clinical presentation; according to Witkop, AI can be categorized into 14 subtypes, which makes its diagnosis extremely complex. Objective: This study aimed to describe and determ

2. The anti-caries activity and toxicity of an experimental propolis-containing varnish
Abstract We investigated the anti-caries effects of an experimental propolis varnish in vivo, and further tested its toxicity against fibroblasts. Fifty-six SPF female Wistar rats were infected with Streptococcus mutans UA159 (SM) and allocated into four groups (n = 14/group): G1, propolis varnish (15%/PV); G2, chitosan varnish (CV/vehicle); G3, gold standar

3. Influence of Different Dentin Substrate (Caries-Affected, Caries-Infected, Sound) on Long-Term μTBS
Resumo O objetivo neste estudo foi avaliar a resistência de união à microtração (RUµT) de um sistema adesivo convencional (Adper Single Bond 2 - SB) em diferentes substratos dentinários e períodos de armazenagem. Vinte e quatro blocos de dentina foram obtidos de terceiros molares hígidos e separados aleatoriamente em 3 grupos (n=8): dentina sadia (D

4. Effect of green tea extract on bonding durability of an etch-and-rinse adhesive system to caries-affected dentin
ABSTRACT Objective Green tea extract has been advocated as a matrix metalloproteinase (MMP) inhibitor; however, its effect on bond durability to caries-affected dentin has never been reported. Thus, the aim of this in vitro study was to evaluate the effect of two MMP inhibitors (2% chlorhexidine and 2% green tea extract), applied after acid etching, on bon

5. Proposta de padronização de método laboratorial para obtenção de dentina afetada por cárie / Laboratorial method proposal to obtain caries-affected dentin
Este estudo se propôs a validar um protocolo para obtenção de dentina afetada por cárie, através do processo in vitro de desmineralização de dentina humana induzida por biofilme de Streptoccocus mutans (método microbiológico). A validação do protocolo foi realizada através de diferentes métodos diagnósticos: inspeção visual, radiografia digit

6. Chlorhexidine does not increase immediate bond strength of etch-and-rinse adhesive to caries-affected dentin of primary and permanent teeth
O objetivo deste estudo foi avaliar o efeito do digluconato de clorexidina (CHX) a 2% na resistência de união imediata de adesivo convencional à dentina decídua hígida (H) e afetada pela lesão de cárie (CA) comparada à dentina permanente. Superfícies dentinárias planas de 20 molares decíduos (Dec) e 20 molares permanentes (Perm) foram divididas em

7. Avaliação por microtração da resistência de sistemas adesivos na dentina sadia e afetada por cárie em dentes humanos / Evaluation of microtensile bond strength of adhesive systems in dentin affected by caries and healthy human teeth
O objetivo deste estudo experimental foi avaliar por microtração a resistência de dois sistemas adesivos em dentina sadia e dentina afetada por cárie em dentes humanos. Para o estudo foram utilizados vinte dentes humanos, sendo dez dentes com a dentina sadia e dez dentes com dentina afetada por cárie. Aleatoriamente, esses dentes foram divididos em quat

8. Evaluation of caries-affected dentin with optical coherence tomography
The purpose of this study was to evaluate the degree of demineralization of artificially induced caries-affected human dentin by an in vitro microbiological method. The occlusal surfaces of 6 human molar teeth were abraded until a flat surface was obtained, and the enamel was removed to expose the occlusal dentin surface. These teeth were sectioned in 12 hal

9. Influência da dentina sadia e afetada por cárie na resistência de união de sistemas adesivos e cimentos de ionômero de vidro em dentes decíduos - estudo in vitro / Influence of sound or caries-affected dentin on the bond strength of adhesive systems and glass ionomer cements in primary teeth an in vitro study
The aim of this study was to evaluate the influence of sound and caries-affected dentin of primary teeth restored with different materials, regarding bond strength and nanoleakage. Seventy two primary second molars received standardized occlusal preparations were randomly assigned in two groups. One group was nominated as sound dentin [SD] (n=36), and the ot

10. CORRELAÇÃO ENTRE GRAU DE CONVERSÃO E RESISTÊNCIA DE UNIÃO DE SISTEMAS ADESIVOS AUTOCONDICIONANTES / CORRELATION BETWEEN DEGREE OF CONVERSION AND BOND STRENGTH OF THE SELF-ETCHING ADHESIVE SYSTEM
Objective: The aim of this study was to analyses the relationship between the degree of conversion of double bonds of self-etching adhesives and microshear bond strength on dentin. Materials and methods: For microshear testing twenty third molar caries free were selected. They had their crowns sectioned longitudinally so as to obtain slices that were randoml

11. Influence of sterilization method on the bond strength of caries-affected dentin
This study evaluated the effect of sterilization method on the bond strength of caries-affected dentin before artificial caries development and after restoration. Twelve bovine incisors were sectioned perpendicularly to their long axes at 7 mm from the amelodentinal junction. They were painted with acid-resistant nail varnish, except on an exposed coronal de

12. Indirect pulp treatment in a permanent molar: case reort of 4-year follow-up
This case report describes the Indirect Pulp Treatment (IPT) of deep caries lesion in a permanent molar. A 16-year-old male patient reported discomfort associated with thermal stimulation on the permanent mandibular left first molar. The radiographs revealed a deep distal caries lesion, very close to the pulp, absence of radiolucencies in the periapical regi
