Effect of atorvastatin on wound healing in rats.

Skin-wound healing is a complex and dynamic biological process involving inflammation, proliferation, and remodeling. Recent studies have shown that statins are new therapeutical options because of their actions, such as anti-inflammatory and antioxidant activity, on vasodilation, endothelial dysfunction and neoangiogenesis, which are independent of their lipid-lowering action. Our aim was to investigate the effect of atorvastatin on tissue repair after acute injury in healthy animals.

Effects of laser irradiation (670-nm InGaP and 830-nm GaAlAs) on burn of second-degree in rats.

This study investigated the effects of 670-nm indium gallium phosphide (InGaP) and 830-nm gallium aluminum arsenide (GaAlAs) laser therapy on second-degree burns induced on the back of Wistar rats. Sixty-three male Wistar rats were anesthetized, and second-degree burns were made on their back. The animals were then divided randomly into three groups: control (C), animals treated with 670-nm InGaP laser (LIn), and animals treated with 830-nm GaAlAs laser (LGa).

Objectives: This study evaluated the wound healing activity of microcurrent application alone or in combination with topical Hypericum perforatum L. and Arnica montana L. on skin surgical incision surgically induced on the back of Wistar rats.

Application of Jatropha curcas L. seed oil (Euphorbiaceae) and microcurrent on the healing of experimental wounds in Wistar rats.

Purpose: To investigate the effects of Jatropha curcas L. seed oil and microcurrent stimulation on the healing of wounds experimentally induced in Wistar rats.

Methods: Forty-eight animals were divided into four groups: (A) control; (B) treated with microcurrent (10 µA/2 min); (C) treated with J.

Use of iontophoresis or phonophoresis for delivering onabotulinumtoxinA in the treatment of palmar hyperidrosis: a report on four cases.

Idiopathic palmar hyperhidrosis is a common disease that exerts a considerable effect on patients' quality of life. The definitive treatment of this condition (sympathectomy) is associated with some adverse effects and surgical risks. Drugs such as onabotulinumtoxinA can be percutaneously delivered by phonophoresis or by iontophoresis and may be useful in the treatment of hyperhidrosis.

Effect of Glycolic Extract of Dillenia indica L. Combined With Microcurrent Stimulation on Experimental Lesions in Wistar Rats.

Unlabelled: This study evaluated the wound healing activity of a glycolic extract of Dillenia indica (GED) prepared from the mature fruits of the plant applied alone or in combination with microcurrent stimulation to skin wounds surgically induced on the back of Wistar rats.

Methods: The animals were randomly divided into six groups: (A) negative control group; (B) group receiving microcurrent application (MC; [10 mA/2 mins]); (C) group treated with GED; (D) group treated with an emulsion containing GED; (E) group treated with GED and MC, and (F) group treated with the emulsion containing GED and MC. Tissue samples were obtained 2, 6, and 10 days after injury and underwent structural and morphometric analysis.

Cephalometric evaluation of surgical mandibular advancement.

The treatment of Class II adult individuals with mandibular deficiency has been the combination of orthodontic treatment and orthognathic surgery. Therefore, a study was conducted in which cephalometric analysis was used to evaluate the influence of dentoalveolar decompensation in Class II patients submitted to orthodontic and surgical treatment for mandibular advancement, by bilateral osteotomy of the mandibular ramus. A sample of 15 leukoderma adult female patients were selected and three cephalometric radiographs of each patient, taken before the orthodontic treatment, before surgery and after at least 6 months postoperatively, were analyzed in a total of 45 roentgenograms.

Effects of the application of Aloe vera (L.) and microcurrent on the healing of wounds surgically induced in Wistar rats.

Purpose: To investigate the effects of topical application of an Aloe vera gel combined or not with microcurrent application on the healing of skin wounds surgically induced in Wistar rats.

Methods: The animals were randomly divided into the following groups: control group, animals topically treated with Aloe vera, animals treated with a microcurrent, and animals receiving topical application of Aloe vera combined with microcurrent application.

Results: The results indicated differences in wound healing between the various treatments when compared to the control group.

Prevalence of malocclusions in a young Brazilian population.

Malocclusions are generally treated in adolescents and adults, but they are established at an early age. The purpose of this study was to determine the prevalence of malocclusions in a young Brazilian population. The sample included 926 children, 8 to 12 years old, attending 5 public schools in the state of Goias, Brazil The type of occlusion was visually determined during the oral exam and statistical analysis, Chi-square test, was performed to correlate the prevalence of malocclusion with gender and with age.

Effect of a papain-based gel for chemomechanical caries removal on dentin shear bond strength.

Purpose: The aim of this study was to assess the shear bond strength of an adhesive restorative system on sound and demineralized dentin after the use of a papain-based agent.

Methods: Forty human dentin slabs were randomly distributed into 4 groups: (1) sound dentin slabs that received an application of papain-based gel (N=10); (2) sound dentin slabs that did not receive a papain-based gel application (N=10); (3) demineralized slabs that received an application of the agent (N=10); and (4) demineralized slabs that did not receive an application of the agent (N=10). After manual excavation and use of the chemomechanical agent, the slabs were restored with a total etch adhesive system and microhybrid resin composite.
