1. Oral manifestations of leukemia as part of early diagnosis
ABSTRACT Introduction: The oral cavity can present the first clinical manifestations of leukemia, therefore; it is important to recognize their principal characteristics. Objective: To identify oral manifestations as the first clinical signs of leukemia. Methods: This is an integrative review, that gathered data from articles with oral manifestations of l

2. Treatment of peri-implant soft tissue defects: a narrative review
Abstract Soft tissue defects around dental implants, such as papilla or volume loss, peri-implant recession and alterations of the ridge color and/or texture, lead to esthetic and functional complaints. Treatments of these defects in implants are more demanding than in teeth because peri-implant tissue exhibits different anatomical and histological character

3. Use of dentifrices to prevent erosive tooth wear: harmful or helpful?
Dental erosion is the loss of dental hard tissues caused by non-bacterial acids. Due to acid contact, the tooth surface becomes softened and more prone to abrasion from toothbrushing. Dentifrices containing different active agents may be helpful in allowing rehardening or in increasing surface resistance to further acidic or mechanical impacts. However, dent

4. Immunohistochemical expression of biglycan and decorin in the pulp tissue of human primary teeth during resorption
Primary teeth are interesting models that can be used to study physiological and pathological processes involving cells and extracellular matrices in hard and soft tissues. This study investigated the expression and distribution of biglycan and decorin-the non-collagenous components of the extracellular matrix-in primary teeth tissue, during physiological ro

5. Simultaneous incorporation of magnesium and carbonate in apatite: effect on physico-chemical properties
Synthetic apatites are widely used both in the dental and the orthopaedic fields due to their similarity in composition with the inorganic phase of hard tissues. Biologic apatites are not pure hydroxyapatite (HA), but are calcium-deficient apatites with magnesium and carbonate as minor but important substituents. The aim of the present study was to produce a

6. Análise morfológica e da resistência adesiva dos tecidos dentais duros irradiados com lasers de pulsos ultracurtos / Evaluation of dental hard tissues irradiated with ultra-short pulsed lasers. Influence on surface morphology and microtensile bond strength
The development of restorative dentistry has reached the era of esthetic adhesive restorations and minimally invasive approach, for which innovative techniques and advanced materials are constantly introduced. Conservative techniques aim not only to remove carious dental substrate, but also to prepare cavity surfaces for adhesive restoration. The main object

7. pH-cycling models for in vitro evaluation of the efficacy of fluoridated dentifrices for caries control: strengths and limitations
Despite a plethora of in situ studies and clinical trials evaluating the efficacy of fluoridated dentifrices on caries control, in vitro pH cycling models are still broadly used because they mimic the dynamics of mineral loss and gain involved in caries formation. This paper critically reviews the current literature on existing pH-cycling models for the in v

8. Evidências preliminares da eficácia de um enxaguante bucal contendo 5% de própolis para o controle de placa e gengivite
Mouthwash based on medicinal plants and propolis can be easily found in the Brazilian market even if it has not been tested in reliable clinical trials on its efficacy or possible unpleasant side effects like the ones which alter the hard and soft oral tissues. The aim of this study was to obtain preliminary evidence of efficacy of an alcohol-free mouthwash

9. Assessment of proximal caries lesions through microtomography, cone beam CT and digital radiographs / Avaliação de cáries proximais por meio da microtomografia, tomografia Cone Beam e radiografias digitais
Dental caries is still a great challenge to dentists, manly in proximal surfaces due to its difficult diagnosis. Many types of equipment have been designed to minimize this problem, specially aiming early caries detection. Among all, one of the most used by clinicians is the interproximal radiograph. The International Caries Assessment System (ICDAS) is a cl

10. Avaliação da regeneração ossea em defeitos peri-implantares de deiscencia tratados com uma abordagem combinada associando celulas derivadas da medula ossea e regeneração ossea guiada : estudo histomorfometrico em cães / Evaluation of bone regeneration in dehiscence type peri-implant defects treated with a combined approach using bone marrow-derived cells and guided bone regeneration : a histomorphometrical study in dogs
The purpose of this investigation was to histometrically evaluate the bone healing in surgically created dehiscence-type defects around titanium implants treated with an association of bone marrow-derived cells (BMCs) and guided bone regeneration (GBR). Bone marrow cells were harvested from eight male adult beagle dogs, cultured in vitro and phenotypically c

11. Propriedades mecanicas e radiodensidade de esmalte, de dentina e de diferentes materiais odontologicos / Mechanical properties and radiodensity of enamel and dentin, and different dental materials
Dental materials development has stimulated the study of their physical and mechanical properties and the substitution of human teeth in dental researches makes necessary the analysis of physical, microstructural and mechanical properties of bovine teeth, varying the age of animals and comparing the results with those from human teeth. In order to fulfill al

12. Influência da irradiação com laser de Er, Cr:YSGG na resistência de união de sistemas adesivos em esmalte e dentina / Er,Cr:YSGG laser irradiation influence on enamel and dentin bond strength of adhesive systems
Este trabalho teve o objetivo de avaliar a resistência adesiva de sistemas adesivos baseados no condicionamento prévio com ácido fosfórico (etch-and-rinse) e auto-condicionantes (de um e dois passos) ao substrato dental, submetido a diferentes condições de irradiação com laser de Er,Cr:YSGG. Amostras de esmalte e dentina foram obtidas do terço médi
