Dynamics, Efficacies, and Adverse Effects of Maxillary Full-Arch Intrusion Using Temporary Anchorage Devices (Miniscrews): A Finite Element Analysis.

Introduction: Absolute anchorages obtained from temporary anchorage devices (TADs, miniscrews) considerably facilitate dental movements and make some very difficult movements such as full-arch intrusions possible. Despite the significance of assessing strategies to fully intrude the arch using mini-implants, there is no study in this regard except a few case reports. Therefore, we simulated/tested 4 scenarios.

Characteristics and Dynamics of Full Arch Distalization Using Transpalatal Arches with Midpalatal and Interradicular Miniscrews as Temporary Anchorage Devices: A Preliminary Finite Element Analysis.

Introduction: Miniscrews have proved quite effective in fixed orthodontic treatment. They can be placed in areas like palatal interradicular zones or midpalatal suture. Despite the value of these methods and their ever-increasing use, their characteristics are not assessed before when implanted in palatal interradicular areas or in the midpalatal suture.

Investigating The Antimicrobial Activity Of Different Root Canal Filling Pastes In Deciduous Teeth.

Background: The antiseptic property of root canal filling materials is very important for the removal of residual pathogens from root canals. The aim of the current study was to investigate the antimicrobial activity of mineral trioxide aggregate (MTA), calcium hydroxide (CH), Metapex, zinc oxide eugenol (ZOE), and CEM-cement.

Materials And Methods: Four standard bacterial strains including (ATCC 6538), (ATCC 29212), (ATCC 27853), and (ATCC 6633) and (ATCC 10231) were used.

The Effect of MIpaste Plus and Reminpro on Incipient Caries Using DIAGNOdent and SEM: An Invitro Study.

Background: The remineralization of early caries lesion has an effective role on decreasing caries. For initial remineralization of caries lesion, using Compounds of Casein phosphopeptides (CPP) in different studies has been proposed. REMINPRO including Fluoride, Xylitol and Calcium phosphate has just been offered in the market.

Comparative evaluation of shear bond strength of metallic brackets bonded with two different bonding agents under dry conditions and with saliva contamination.

Background: This study compared the shear bond strength of metallic brackets bonded with Single Bond and Assure bonding agents under dry and saliva-contamination conditions.

Methods: Sixty sound premolar teeth were selected, and stainless-steel brackets were bonded on enamel surfaces with Single Bond and Assure bonding agents under dry condition or with saliva contamination. Shear bond strength values of brackets were measured in a universal testing machine.

Evaluation of orthodontic treatment needs using the dental aesthetic index in Iranian students.

Background: In the contemporary orthodontics, the number of people who demand orthodontic treatment to improve their psychosocial issues related to facial esthetic is constantly increasing. Even in treatment plans, appearance and esthetic gain more attention.

Objectives: The purpose of this study was to determine the need for orthodontic treatment on the basis of the dental aesthetic index (DAI) in the Iranian students of Ahvaz city.

Survey on the Condition of First Permanent Molars in 15-year-old Students in Ahwaz, Iran in 2005.

Background And Aims: Many children still face active and uncontrolled dental caries and data is needed for evaluating the situation in many parts of the country. The aim of the present survey was to evaluate the oral health of the young population of Ahwaz, Iran in 2005.

Materials And Methods: In this descriptive cross-sectional study, 600 15-year-old students were se-lected randomly.
