We have previously demonstrated that a linalool‐rich essential oil from Croton cajucara Benth presents leishmanicidal activity. In the present study, we demonstrate this inhibits growth of reference samples Candida albicans , Lactobacillus casei, Staphylococcus aureus, Streptococcus sobrinus, Porphyromonas gingivalis and mutans cell suspensions all them associated with oral cavity disease. The purified linalool fraction was only inhibitory for C. . Microbes saliva specimens human individuals...

Abstract Objective: To verify whether bone mineral density (BMD) of cortical bone, trabecular and total influence the primary stability orthodontic miniscrews to there is a correlation between measurement BMD by cone-beam computed tomography (CBCT) central dual-energy x-ray absorptiometry (DEXA). Materials Methods: Twenty bovine sections were extracted from pubic iliac bones regions with thicknesses approximately 1 mm. The block was evaluated using two methods: CBCT DEXA. cortical,...

ABSTRACT Objective: To compare the primary stability of miniscrews inserted into bone blocks different mineral densities (BMDs) with and without cortical bone, investigate whether some trabecular properties could influence stability. Materials Methods: Fifty-two were extracted from fresh bovine pelvic bone. Four groups created based on type (iliac or pubic region) presence absence Specimens micro-computed tomography imaged to evaluate thickness, number, separation, volume density (BV/TV),...

This study was conducted to identify and characterize dental follicle stem cells (DFSCs) by analyzing expression of embryonic, mesenchymal neural surface markers. Design Dental (DFCs) were evaluated immunocytochemistry using embryonic markers (OCT4 SOX2), mesenchmal (MSCs) (Notch1, active Notch1, STRO, CD44, HLA-ABC, CD90), (Nestin β-III-tubulin), crest (NCSCs) (p75 HNK1) a glial marker (GFAP). RT-PCR performed the OCT4 NANOG in DFCs tissue.Immunocytochemistry analysis revealed that...

The aim of the study was to investigate routine, sleep history, and orofacial disorders associated with children aged 3-7 years nocturnal bruxism.Children (n = 66) were divided into groups parent reported bruxism 34) those without disorder 32). Data about child's routine during day, awakening, headache frequency, temporomandibular joint (TMJ), hearing impairments obtained through interviews parents/caregivers. Electromyography examination used assess activity facial muscles. Multiple...

Primary stability is absence of mobility in the bone bed after mini-implant placement and depends on quality among other factors. Bone a subjective term frequently considered as density. The aim this preliminary study was to evaluate density two bovine pelvic regions verify primary miniscrews inserted into them. Forty blocks were extracted from bones, 20 iliac pubic bone, all them containing cortical about 1 mm thick. Half sections each designated for histological evaluation (trabecular area...

To evaluate the reasons influencing preferences for a certain type of orthodontic appliance over another among prospective patients (PP) and orthodontists.A total 49 PP 51 orthodontists were asked about their following appliances: clear aligners (CA), lingual metallic brackets (LMB), polycrystalline monocrystalline ceramic brackets, buccal (BMB). The participants rated importance 17 potential that would explain choices. contributed most to these identified. Non-parametric tests (Fisher's...

The aim of this study was to assess by means cone-beam computed tomography (CBCT) scans the transverse effects on nasomaxillary complex in patients submitted rapid maxillary expansion (RME) using Haas expander comparison untreated individuals. This prospective controlled clinical assessed 30 subjects (18 boys and 12 girls) with mixed dentition during pubertal growth. treated group RME expander, retention for six months a six-month follow-up after removal. control matched terms age sex...

OBJETIVO: avaliar por meio de Tomografia Computadorizada Cone-Beam (TCCB) os efeitos transversais, imediatos e após o período contenção, da expansão rápida maxila (ERM) em pacientes com má oclusão Classe II. MÉTODOS: dezessete crianças (idade inicial média 10,36 anos) II deficiência transversal esquelética foram submetidas ao protocolo ERM aparelho expansor Haas. TCCBs realizadas antes dos procedimentos clínicos (T1), imediatamente a estabilização do parafuso (T2) completados 6 meses...

The aim of this study was to test the hypothesis that there is no difference in fluoride release behavior resin-reinforced glass ionomer cements before or after recharge. materials were divided into 5 groups: 2 used for attaching orthodontic bands, is, group FOB (Fuji Ortho Band) and MCB (Multi-Cure Glass Ionomer Orthodontic Band Cement); a composite bonding brackets, OGLC (Ortho LC), FOLC TXT (Transbond XT), respectively. Fluoride measured during 60-day period by using selective ion...

The hypothesis tested in this study was that intraoral exposure of elastomeric chains alters their tensile strength. For such purpose, it evaluated the situ behavior different stretched for 3 weeks. Three kinds chains, Plastic chain (PC), Memory (MC) and Super slick (SSC), were randomly placed quadrants 13 patient a fixed distance 16 mm mean initial force 180 g. Tensile testing performed an universal machine at intervals: initial, 1 h, 24 week, 2 weeks A two-way ANOVA test to identify...

The degradation of elastic ligatures in the oral environment results need periodic replacement to maintain optimal force during orthodontic treatment. purpose this study was perform a clinical prospective randomized elastomeric by scanning electron microscopy (SEM) and tensile strength test.Two hundred were randomly selected placed around brackets 5 volunteers removed groups 10, at different times (1, 2, 3, 4 weeks). control group performed another fifty which not submitted degradation....
