Evaluation of two stereophotogrametry software for 3D reconstruction of virtual facial models.

Objective: The present study aimed to evaluate the accuracy of 3D facial soft tissue virtual models produced by two photogrammetry softwares (AgiSoft Photoscan and 3DF Zephyr Free), when compared to those created by cone beam computed tomography (CBCT).

Methods: Ten patients were submitted to two sequences of photographs performed with a DSLR camera (with and without the aid of a ring flash) and CBCT scans. Each photo series for each patient was processed with the softwares, and at the end, five models of each patient were generated: 1) CBCT, 2) AAL (Agisoft Ambient Light), 3) AFL (Agisoft Flash Light), 4) ZAL (Zephyr Ambient Light), and 5) ZFL (Zephyr Flash Light).

The Gingival Crevicular Fluid as a Source of Biomarkers to Enhance Efficiency of Orthodontic and Functional Treatment of Growing Patients.

Gingival crevicular fluid (GCF) is a biological exudate and quantification of its constituents is a current method to identify specific biomarkers with reasonable sensitivity for several biological events. Studies are being performed to evaluate whether the GCF biomarkers in growing subjects reflect both the stages of individual skeletal maturation and the local tissue remodeling triggered by orthodontic force. Present evidence is still little regarding whether and which GCF biomarkers are correlated with the growth phase (mainly pubertal growth spurt), while huge investigations have been reported on several GCF biomarkers (for inflammation, tissue damage, bone deposition and resorption, and other biological processes) in relation to the orthodontic tooth movement.

Effect of orthodontic force on expression levels of ten cytokines in gingival crevicular fluid.

Various types of inflammatory mediators are involved in the cascade of biological events behind tissue remodeling allowing orthodontic tooth movement. This split-mouth longitudinal study aimed to evaluate the gingival crevicular fluid (GCF) levels of ten cytokines, IL-6, IL-8, IL-10, IL-13, IL-17, IFN-γ, GM-CSF, MCP-1, MIP-1β and TNF-α, during initial orthodontic treatment. The sample comprised 15 healthy patients (9 males and 6 females, 13.

Health in Action Program, Brazil: a Program Impact Pathways (PIP) analysis.

Background: The Health in Action Program was established in Brazil in 2010 to address the critical issues of health and nutrition among vulnerable children in the northeast and southeast regions of the country. By offering school-based nutrition education and increased access to nutritious foods from school gardens, the program has benefited more than 200,000 children aged 6 through 14 years in 430 schools and an additional 670,000 family and community members. The program is now expanding to reach an additional 260,000 students in 570 schools.

Levels of gingival crevicular fluid matrix metalloproteinases in periodontally compromised teeth under orthodontic forces.

Objective: To examine levels of matrix metalloproteinases (MMPs)-1, -2, -3, -7, -8, -12, and -13 in the gingival crevicular fluid (GCF) of periodontally compromised teeth at different time points during orthodontic movement.

Materials And Methods: Ten controlled periodontitis subjects were submitted to orthodontic treatment. One dental arch was subjected to orthodontic movement, and teeth in the opposite arch were used as controls.

Orthodontic and surgical treatment of a patient with hemifacial microsomia.

This article describes the surgical and orthodontic treatment of a 12-year-old boy with a significant deformity and functional involvement caused by hemifacial microsomia.

Matrix metalloproteinases and chemokines in the gingival crevicular fluid during orthodontic tooth movement.

Matrix metalloproteinases (MMPs) and monocyte chemoattractants are key modulators of the biological mechanisms triggered in the periodontium by mechanical forces. The gingival crevicular fluid (GCF) provides a non-invasive method to assess longitudinally the release of inflammatory mediators during orthodontic tooth movement. The goal of this study was to examine the GCF levels of MMP-3, MMP-9, and MMP-13 and of the chemokines macrophage inflammatory protein (MIP)-1β, monocyte chemoattractant protein (MCP)-1, and regulated on activation normal T cells expressed and secreted (RANTES) at different time points during orthodontic tooth movement.

The monitoring of gingival crevicular fluid volume during orthodontic treatment: a longitudinal randomized split-mouth study.

Unlabelled: This randomized split-mouth study was aimed at evaluating whether an orthodontic appliance per se or orthodontic tooth movement can induce detectable changes in gingival crevicular fluid (GCF) volume, and thus whether GCF volume is a predictable biomarker for tissue remodelling incident to orthodontic tooth movement.

Materials And Methods: Sixteen healthy orthodontic patients (7 females and 9 males; mean age, 17.7 years; range, 13-27 years) with the need for extraction of the first upper premolars were enrolled.

Correlates affecting survival in chronic hemodialysis patients: the combined impact of albumin and high hemoglobin levels on improving outcomes, local and national results.

While national mortality rates for end-stage renal disease (ESRD) patients remain high, for the past 4 years, lower than expected local mortality rates have been consistently seen in our facilities. Because of these progressive improvements in mortality rates, a study of 687 hemodialysis patients over a 4-year period, 2003 through 2006, was undertaken to analyze which factors may be contributing to the enhanced survival rates. We also examined the partially overlapping United States Renal Data System clinical performance measures national data sets of hemodialysis patients for 2001 to 2004.

Ecology and management of rodents in no-till agriculture in Washington, USA.

No-till farming is an important approach to sustainable agriculture because it can conserve soil and water resources. Unfortunately, rodent populations can thrive under no-till conditions because burrow systems are not disrupted by annual plowing and plant residues build-up on the surface, providing cover and insulation. This can result in substantial crop damage.

Orthodontic and surgical treatment of a patient with an ankylosed temporomandibular joint.

This article describes the surgical and orthodontic treatment of a girl with facial deformities and functional involvement. The left temporomandibular joint was ankylosed, and the lower third of the face was markedly deficient, with mandibular retrusion and severe laterognathism to the left side. Mouth-opening was limited, and the patient had problems speaking and chewing.
