1. Enamel and dentine demineralization by a combination of starch and sucrose in a biofilm – caries model
Abstract Sucrose is the most cariogenic dietary carbohydrate and starch is considered non-cariogenic for enamel and moderately cariogenic for dentine. However, the cariogenicity of the combination of starch and sucrose remains unclear. The aim of this study was to evaluate the effect of this combination on Streptococcus mutans biofilm composition and enamel

2. In vivo model for microbial invasion of tooth root dentinal tubules
ABSTRACT Objective Bacterial penetration of dentinal tubules via exposed dentine can lead to root caries and promote infections of the pulp and root canal system. The aim of this work was to develop a new experimental model for studying bacterial invasion of dentinal tubules within the human oral cavity. Material and Methods Sections of human root dentin

3. Fluoride rinse effect on retention of CaF2 formed on enamel/dentine by fluoride application
Abstract Calcium fluoride-like materials (“CaF2”) formed on dental surfaces after professional fluoride application are unstable in the oral environment but can be retained longer with a daily NaF mouthrinse. We tested the effect of twice daily 0.05% NaF rinses on the retention of “CaF2” formed on enamel and dentine after applying acidulated phosphat

4. Effect of high energy X-ray irradiation on the nano-mechanical properties of human enamel and dentine
Abstract Radiotherapy for malignancies in the head and neck can cause common complications that can result in tooth damage that are also known as radiation caries. The aim of this study was to examine damage to the surface topography and calculate changes in friction behavior and the nano-mechanical properties (elastic modulus, nanohardness and friction coef

5. Anti-dentine Salivary SIgA in young adults with a history of dental trauma in deciduous teeth
Anti-dentin autoantibodies are associated with inflammatory root resorption in permanent teeth and are modulated by dental trauma and orthodontic force. However, it is not known whether deciduous tooth trauma can stimulate the development of a humoral immune response against dentin. The aim of this study was to evaluate the levels of salivary SIgA reactiv

6. Caries risk assessment in schoolchildren - a form based on Cariogram® software
Identifying caries risk factors is an important measure which contributes to best understanding of the cariogenic profile of the patient. The Cariogram® software provides this analysis, and protocols simplifying the method were suggested. Objectives: The aim of this study was to determine whether a newly developed Caries Risk Assessment (CRA) form based on

7. 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

8. Efficacy of chemomechanical caries removal in reducing cariogenic microbiota: a randomized clinical trial
The aim of this study was to compare the efficacy of chemochemical methods (Carisolv™ and Papacárie®) versus the manual method (excavators) in reducing the cariogenic microbiota in dentine caries of primary teeth. Forty-six healthy children (5 to 9 years old) having at least one primary tooth with a cavitated dentine carious lesion were included in the s

9. The effect of fluoride toothpaste on root dentine demineralization progression: a pilot study
The anticaries effect of fluoride (F) toothpaste containing 1100 µg F/g in reducing enamel demineralization is well established, but its effect on dentine has not been extensively studied. Furthermore, it has been shown that toothpaste containing a high F concentration is necessary to remineralize root dentine lesions, suggesting that a 1100 µg F/g concent

10. Dentine microhardness after different methods for detection and removal of carious dentine tissue
There are several methods for identifying carious dentinal tissue aiming to avoid removal of healthy dentinal tissue. OBJECTIVES: The purpose of this study was to test different methods for the detection of carious dentinal tissue regarding the amount of carious tissue removed and the remaining dentin microhardness after caries removal. MATERIAL AND METHODS:

11. In situ anticariogenic effect of conventional glass ionomer cement by dentrifice dependence / Efeito anticariogênico de cimento de ionômero de vidro convencional pela dependência de dentrifício: estudo "in situ"
The aim of this study was to assess in situ anticaries potential of conventional glass ionomer cement (GIC) to prevent enamel and dentine demineralization either alone or in combination with a fluoride (F) regimen. A randomized, blind, crossover design for caries induction was carried out in 2 phases of 14 days each. This study was a 2 x 2 cross-over factori

12. 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
