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).
Objectives: To analyze histologic findings of bone remodeling at the time of surgery and 90 days later at corticotomized and noncorticotomized sites.
Materials And Methods: Eight adult patients with bilaterally inclined mandibular molars were included in this split-mouth study. Corticotomy was performed on the test side, and bone was harvested on both mandibular hemi-arches.

Objective: to describe the measurement process of the body mass in children under seven years old, assisted by community health agents in primary health care units of the Family Health Strategy, in Macaé-RJ, Brazil.
Methods: a descriptive study with community health agents who measured the body mass of children, from August 2010 to August 2011.
Results: ¾ (n=65) of the community health agents from Macaé Primary Health Care were observed in 196 measurements; in 66.
Introduction:: Digital dental models provide a more accurate and comprehensive assessment of orthodontic cases. Although this technique is quite promising, there are few three-dimensional measurements methods described in the literature.
Objective:: The aim of this study was to propose a method for assessing the degree of mandibular anterior dental crowding in the three planes of space, using digital dental models.
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.
