Women's oral health-related quality of life as a risk factor for TMD symptoms. A case-control study.

Objective: To investigate the association between temporomandibular disorder (TMD) symptoms and women's oral health-related quality of life (OHRQoL).: An observational case-control study was performed with 765 adult women aged 21.5 years on average.

How is orthodontic treatment need associated with perceived esthetic impact of malocclusion in adolescents?

Introduction: The purpose of this research was to evaluate the esthetic impact of orthodontic treatment need in adolescents.

Methods: This cross-sectional study was performed with 1172 adolescents aged 12 (n = 638) years and 15 (n = 534) years from Salvador, Bahia, Brazil. The esthetic impact was the following outcome variables: Aesthetic Component of the Index of Orthodontic Treatment Need and the Oral Aesthetic Subjective Impact Scale.

Argon Atmospheric Plasma Treatment Promotes Burn Healing by Stimulating Inflammation and Controlling the Redox State.

Burns are a public health problem, with second-degree burns as one of the most common types. Although intense inflammation worsens burn healing, effective therapies are scarce. Thus, infections and hypertrophic scars may occur, which compromise patient quality of life and may delay healing.

Evaluation of the Effectiveness of Crotoxin as an Antiseptic against spp. Biofilms.

The growing number of oral infections caused by the Candida species are becoming harder to treat as the commonly used antibiotics become less effective. This drawback has led to the search for alternative strategies of treatment, which include the use of antifungal molecules derived from natural products. Herein, crotoxin (CTX), the main toxin of venom, was challenged against (CBS94) and (CBS7987) strains by in vitro antimicrobial susceptibility tests.

Effects of Percutaneous Collagen Induction Therapy Associated with Hyaluronic Acid on Inflammatory Response, Oxidative Stress, and Collagen Production.

Percutaneous collagen induction (PCI) is an alternative treatment for skin dysfunctions, it aims to stimulate collagen production by encouraging normal wound healing that occurs after any trauma by inducing microlesions; also it may be potentiated with the association with drugs such as hyaluronic acid (HA). Our objective was to evaluate the effects of PCI associated with hyaluronic acid (0.9%) on inflammatory process, oxidative stress, and collagen production in rat epidermis.

Microcurrent and adipose-derived stem cells modulate genes expression involved in the structural recovery of transected tendon of rats.

Tendon injuries are common and have a high incidence of re-rupture that can cause loss of functionality. Therapies with adipose-derived stem cells (ASC) and the microcurrent (low-intensity electrical stimulation) application present promising effects on the tissue repair. We analyzed the expression of genes and the participation of some molecules potentially involved in the structural recovery of the Achilles tendon of rats, in response to the application of both therapies, isolated and combined.

Laser treatment of synovial inflammatory process in experimentally induced microcrystalline arthritis in Wistar rats.

The presence of intra-articular crystals is detected in different articular pathologies of acute or chronic nature. The aim of this work was to analyze the action of the indium gallium aluminum and phosphorus (InGaAlP) (λ = 670 nm) laser on the synovial membrane present in the knee joint in experimentally induced microcrystalline arthritis in male adult Wistar rats. The animals were divided into three experimental groups (n = 24): control (A), experimentally induced arthritis (B), experimentally induced arthritis+InGaAlP laser therapy (C).

Inhibitory effect of red LED irradiation on fibroblasts and co-culture of adipose-derived mesenchymal stem cells.

The objective of this study was to evaluate the effects of red Light Emiting Diode (red LED) irradiation on fibroblasts in adipose-derived mesenchymal stem cells (ASC) co-culture on the scratch assay. We hypothesized that red LED irradiation could stimulate paracrine secretion of ASC, contributing to the activation of genes and molecules involved in cell migration and tissue repair. ASC were co-cultured with NIH/3T3 fibroblasts through direct contact and subjected to red LED irradiation (1.

Experimental models and methods for cutaneous wound healing assessment.

Wound healing studies are intricate, mainly because of the multifaceted nature of the wound environment and the complexity of the healing process, which integrates a variety of cells and repair phases, including inflammation, proliferation, reepithelialization and remodelling. There are a variety of possible preclinical models, such as in mice, rabbits and pigs, which can be used to mimic acute or impaired for example, diabetic and nutrition-related wounds. These can be induced by many different techniques, with excision or incision being the most common.

Exploring the perception of orthodontic treatment need using the Dental Aesthetic Index and Index of Orthodontic Treatment Need.

Introduction: This study aimed to explore the perception of orthodontic treatment need by using the Dental Aesthetic Index (DAI) and the Index of Orthodontic Treatment Need (IOTN).

Methods: A cross-sectional study was conducted on a representative random sample (N = 248) of adolescents aged 12 years. The DAI and both components of IOTN were used to evaluate malocclusion.

Malocclusion, facial and psychological predictors of quality of life in adolescents.

Objective: To identify clinical and psychological predictors of OHRQoL.

Methods: Cross-sectional clinical and questionnaire study with 332 adolescents aged 11-14 years. The facial profile was classified through photographs and dental malocclusion was classified by the Dental Health Component of the Index of Orthodontic Treatment Need.

Anxiety and oral habits as factors associated with malocclusion.

: The aim of this study was to associate the presence of oral habits with anxiety and malocclusion.: Cross-sectional observational study with 199 schoolchildren 6-14 years old. Malocclusion was evaluated by using the Index of Orthodontic Treatment Need (IOTN).
