1. Análise da atividade antimicrobiana de probióticos e sua adesividade a bráquetes ortodônticos: estudo in vitro
Resumo Introdução A presença de aparelho ortodôntico fixo dificulta a higienização e potencializa o acúmulo de biofilme bacteriano nas superfícies dentárias. O desenvolvimento de produtos que minimize isso é desejo de pesquisadores em todo o mundo. Objetivo Verificar a ação bacterapêutica de produtos lácteos contendo ou não probióticos sob

2. Antibacterial and Cytotoxic Potential of a Brazilian Red Propolis
Abstract Objective: To evaluate in vitro the effect of a red propolis ethanolic extract (RPE) in the prevention of growth of a cariogenic biofilm and its cytotoxic potential. Material and Methods: Minimum inhibitory and bactericidal concentrations (MIC and MBC) of RPE against Streptococcus mutans and Lactobacillus casei were determined. The cytotoxic poten

3. Effect of Bulgarian propolis on the oral microflora in adolescents with plaque-induced gingivitis
ABSTRACT We compared the effect of two therapeutic approaches (marketed toothpaste and addition of Bulgarian propolis extract to the toothpaste) on gingival inflammation, plaque formation and oral microbial flora on Bulgarian adolescents with moderate plaque-induced gingivitis. The participants were divided randomly into two groups of 35 students. The first

4. Antibiofilm Activity of an Experimental Ricinus Communis Dentifrice on Soft Denture Liners
Resumo A desvantagem dos materiais resilientes é a dificuldade de controle do biofilme. Este estudo comparou um dentífrico experimental contendo Ricinus communis, com dentifrícios comerciais quanto atividade contra biofilme formado em reembasador de próteses totais. Seiscentos espécimes foram distribuídos em 5 grupos (n=18/microrganismo): água; dentif

5. Evaluation of an antibacterial orthodontic adhesive incorporated with niobium-based bioglass: an in situ study
Abstract This in situ study aimed to evaluate the antibacterial and anti-demineralization effects of an experimental orthodontic adhesive containing triazine and niobium phosphate bioglass (TAT) around brackets bonded to enamel surfaces. Sixteen volunteers were selected to use intra-oral devices with six metallic brackets bonded to enamel blocks. The experim

6. Antibacterial, chemical and physical properties of sealants with polyhexamethylene guanidine hydrochloride
Abstract The aim of this study was to evaluate the influence of polyhexamethylene guanidine hydrochloride (PHMGH) in the physico-chemical properties and antibacterial activity of an experimental resin sealant. An experimental resin sealant was formulated with 60 wt.% of bisphenol A glycol dimethacrylate and 40 wt.% of triethylene glycol dimethacrylate with a

7. Inhibitory effect of reduced graphene oxide-silver nanocomposite on progression of artificial enamel caries
Abstract The use of antimicrobial agents is an efficient method to prevent dental caries. Also, nanometric antibacterial agents with wide antibacterial spectrum and strong antibacterial effects can be applied for prevention of dental caries. Objectives: The aim of this study was to evaluate the inhibitory effect of reduced graphene oxide-silver nanoparticle

8. Effects of a food enriched with probiotics on Streptococcus mutans and Lactobacillus spp. salivary counts in preschool children: a cluster randomized trial
Abstract Probiotics have provided benefits to general health, but they are still insufficient to dental health. Objective: This study aimed to evaluate milk supplemented with probiotic bacteria and standard milk, measured by levels of Streptococcus mutans (S. mutans) and Lactobacillus spp., in 3-4-year-old children after 9 months of intervention. Material

9. Influence of biofilm formation on the mechanical properties of enamel after treatment with CPP-ACP crème
Abstract: The study aimed to investigate the effects of bacterial biofilms on changes in the surface microhardness of enamel treated with casein phosphopeptide—amorphous calcium phosphate (CPP-ACP) with and without fluoride. Human enamel blocks with incipient caries-like lesions were divided into four groups of 13: G1: Saliva (Control); G2: fluoride dentif

10. In vitro and in vivo evaluations of glass-ionomer cement containing chlorhexidine for Atraumatic Restorative Treatment
Abstract Objectives: Addition of chlorhexidine has enhanced the antimicrobial effect of glass ionomer cement (GIC) indicated to Atraumatic Restorative Treatment (ART); however, the impact of this mixture on the properties of these materials and on the longevity of restorations must be investigated. The aim of this study was to evaluate the effects of incorp

11. 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

12. Salivary density of Streptococcus mutans and Streptococcus sobrinus and dental caries in children and adolescents with Down syndrome
Abstract Streptococcus mutans and Streptococcus sobrinus are strongly associated with dental caries. However, the relationship between oral streptococci and dental caries in children with Down syndrome is not well characterized. Objective To assess and compare dental caries experience and salivary S. mutans, S. sobrinus, and streptococci counts between gro
