Introduction Phytotherapy is the study of herbal medicines and their applicability to cure diseases in general, being a therapeutic method which can be used for the prevention and treatment of mouth diseases. Among the herbal studied, the Libidibia ferrea, known as jucá or ironwood, is widely used in folk medicine by presenting anti-inflammatory, analgesic, antimicrobial and antipyretic therapeutic properties. Objective To evaluate in vitro pharmacological stability of the Libidibia ferrea extract’s mouthwash (INPA - 228 022). Material and method It was held the mouthwash microbiological control by determining the total number of microorganisms and Salmonella sp, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus; stability characteristics (color, odor, brightness and consistency), sedimentation test (centrifuge), the pH measurement (pH meter) and density evaluation (pycnometer) were analyzed. Result The mouthwash showed to be absent from microorganisms and no changes were observed in the organoleptics and sedimentation characteristics. The average pH values were 6.21, 6.15 and 5.85 at 0, 30 and 60 days, respectively, and 1.029, 1.033 and 1.035 g/ mL density values, respectively, without interfering with the final characteristic of the formulation. Conclusion The mouthwash presented pharmacological stability and quality conditions.
Amazonian biodiversity products that have been used for years in folk medicine, have emerged as feasible and promising alternatives for the inhibition of microorganisms in dental biofilm. Copaiba oil, a phytotherapic agent widely used by the Amazonian populations, is known for its antibacterial, anti-inflammatory, anesthetic, healing and antitumor medicinal properties.Objective:The aim of this study was to evaluate the in vitro antibacterial activity of copaiba oil (Copaifera multijuga) gel against strains of Streptococcus sp present in dental biofilm.Materials and Methods:The copaiba oil was obtained and the chemical components were identified. The oil emulsions were formulated and used with the Brain Heart Infusion agar diffusion method with strains of Streptococcus mitis, Streptococcus constellatus and Streptococcus salivarius isolated from patients as well as standard strains of S. mitis (ATCC903), S. mutans (ATCC10449), S. sanguinis (ATCC15300) and S. oralis (ATCC10557). The study groups were as follows: experimental copaiba oil gel, 1% chlorhexidine gel (positive control) and base gel (negative control). The seeded plates were incubated at 37ºC for 12, 24 and 48 hours, respectively. The results obtained were analyzed by Shapiro-Wilk and Friedman Tests (p<0.05) for non parametric data and the Tukey test was used for pH values with 5% level of significance. Results:The experimental copaiba oil gel and 1% chlorhexidine gel showed antibacterial activity against the tested microorganisms.Conclusion: The copaiba oil gel demonstrated antibacterial activity against all the strains of Streptococcus sp tested, suggesting that it can be used for dental biofilm control.
Introdução: Os diastemas são espaços interdentais que ocorrem nos arcos superior e inferior, tanto em dentes anteriores como em dentes posteriores, sendo mais frequentes em dentes anterossuperiores. Sua etiologia é multifatorial e deve ser avaliada com cautela para que o tratamento correto seja realizado e concluído com sucesso. Objetivo: Dessa maneira, o presente artigo possui como objetivo relatar um caso clínico em que se optou pela confecção de facetas em resina composta direta para o fechamento dos diastemas. Caso clínico: Paciente de 21 anos, procurou atendimento no curso de graduação em Odontologia da Universidade Nilton Lins queixando-se do espaço que havia entre seus incisivos superiores. Após exame clínico foi sugerida a confecção de facetas em resina composta pela técnica direta. Conclusão: Por meio deste caso clínico conclui-se que a realização de facetas utilizando materiais adesivos se destaca por reduzido tempo de trabalho e baixo custo. Mostrando ser uma técnica eficaz no restabelecimento dos aspectos funcionais e estéticos do sorriso.
The role of dentin cleaning is to remove debris that may impair adaptation and marginal sealing, quantitatively reducing microorganisms. The aim of this study was to investigate through scanning electron microscopy (SEM) the morphology of the dentin surface, cut and treated with copaiba oil emulsions (CO) and suspension of ethanol extract of propolis (EP). Twenty four upper pre-molars teeth, divided into eight groups (n=3), were used: G1: no cleaning, G2: air/water spray, G3: 10% CO, G4: 10% CO + A, G5: 30% CO, G6: 30% CO + A, G7: 1% EP, G8: 2% Chlorhexidine. The specimens were dentin discs (1 mm Ø). The SEM photomicrographs were classified and the results were: G1 - Debris dentin on the entire image / countless microorganisms, G2 and G7 - 50-100 debris / countless microorganisms and G3, G4, G5, G6 and G8 - 0-50 debris / countable microorganisms (50-100 colonies).Conclusion:The present results suggest that copaiba oil emulsions (CO) and suspension of ethanol extract of propolis (EP) have feasibility to be used as bioactive dental cleaning agents.
