Effects of Unilateral Extraction Treatment on Arch Symmetry and Occlusion
… are common in orthodontic patients. A treatment option for correcting moderate asymmetries is asymmetric extractions. This study evaluated post-treatment dental arch symmetry in patients treated with unilateral premolar extractions. Post-treatment casts of 60 patients were divided into …

Factors Associated with Orthodontically Induced Apical Root Resorption of Maxillary Incisors
… apices is a ubiquitous occurrence in orthodontic treatment. Although most occurrence of resorption during orthodontic treatment is clinically inconsequential, a small percentage of patients have a severe amount of root structure that is lost. There are factors that are widely accepted as …

Environmental site characterization via artificial neural network approach
… levels are decreasing due to the use of the Extraction, Treatment, and Recharge (ETR) systems. This research demonstrates the advantages of ANN site characterization modeling in contrast with traditional modeling schemes. Accordingly, characterization task-related uncertainties of site …

Oropharyngeal Airway Volume Following Orthodontic Treatment: Premolar Extraction Versus Non-Extraction
… can be achieved with two distinct methods of treatment. The first involves the extraction of teeth to gain the space needed for tooth alignment. The second relies on arch expansion to gain the space needed for correction. In recent decades, arguments for and against the extraction of teeth for …

A Survey of Treatment Characteristics in a University-based Graduate Orthodontic Program
… actual orthodontic patients and their treatments. The purpose of this study was to describe the patients and their treatment at a university based orthodontic department, namely the University of Tennessee Health Science Center, Memphis. The goals of this study are: (1) to research …

First Premolar Extraction Decisions and Effects
… (TSALD) is to treat patients with the extraction of premolars. Not all of the extraction space, however, is needed to eliminate the patient's TSALD. Also, it is typical that some of the extraction space will be lost because the molars are used as anchorage units to retract the anterior …

THREE-DIMENSIONAL ASSESSMENT OF THE EFFECTS OF EXTRACTION ON THE SMILE IN CLASS II HIGH AND LOW MANDIBULAR PLANE ANGLE PATIENTS
… are filled with studies aimed to understand how extraction orthodontic treatment might change the face. Although many studies have addressed profile changes due to extraction treatment, fewer studies have focused on how extractions change a patients smile. With the advent of surface imaging …

Characterization of blackcurrant berries (Ribes nigrum) and the evaluation of their bioactive compounds after ultrasound-assisted water extractions, enzymatic treatments, and fermentation
… (DPPH·), after water-based ultrasound assisted extraction, treatment with pectinase and fermentation. BC varieties (Titania, D16-6-54, Consort, and D16-8-14) were dissected into parts (juice, seeds, skins) freeze dried, ground and kept at -20 ºC. Parts and whole berries were evaluated to …

Quantitative Analysis of First- versus Second-Premolar Extraction Effects in Orthodontic Treatment
… that have to be resolved by premolar extractions. Treatment planning in such cases usually involves removing first (P1) or second premolars (P2). Choosing an extraction pattern is a learned skill that incorporates many diagnostic factors. This study compared the amounts of in-treatment …
