The Efficacy of Diagnostic Plaster Models in Orthodontic Diagnosis and Treatment Planning.

Background: The growing integration of digital technologies in orthodontics is shifting the orthodontic diagnosis and recordkeeping paradigm, replacing conventional plaster models with intraoral scanning and 3D photography. This study investigated the impact of orthodontic plaster models on orthodontic diagnosis and treatment planning decisions by orthodontists.

Methods: Thirty-three orthodontists assessed six patients' records with different malocclusion cases.

Comparison of Enamel Surface Integrity after De-Bracketing as Affected by Seven Different Orthodontic Residual Cement Removal Systems.

This study used seven different adhesive removal systems to evaluate and compare enamel surface integrity, heat generation, and time consumed during residual cement removal after de-bracketing. The sample size was 140 human premolars. Teeth were cleaned, mounted, and prepared for orthodontic bracket bonding.

Structural Conformation Comparison of Different Clear Aligner Systems: An In Vitro Study.

The aim of this study was to evaluate the structural conformations of three clear aligner systems, Eon, SureSmile, and Clarity, and compare them with the most commonly used system, Invisalign. Clear aligner samples from Invisalign, Eon, SureSmile, and Clarity were cut into 5 × 5 mm squares and exposed to artificial saliva for 2 weeks. The specimens were then subjected to a Vickers hardness test by applying three separate indentations with a 25 gf load for 15 s.

The effect of vitamin D deficiency on the RANKL/OPG ratio in rats.

The aim of this study was to determine the effect of vitamin D deficiency on the RANKL/OPG ((Receptor Activator of Nuclear Factor Kappa B Ligand/Osteoprotegerin) ratio in the serum blood levels. Sixteen Wistar rats were divided into 2 groups: a control group (C) and an experimental group (E). The group C comprised of rats with average vitamin D levels, while vitamin D deficiency was induced in those of group E.

Effects of vitamin D deficiency on the rate of orthodontic tooth movement: An animal study.

Unlabelled: Bone remodeling and orthodontic tooth movement (OTM) are controlled by certain essential molecules, one of which is vitamin D. Increased levels of vitamin D have been associated with increased rates of OTM. The purpose of this study was to determine the effect of vitamin D deficiency on the rate of OTM, and to determine their association after applying orthodontic forces.

Leaching of Different Clear Aligner Systems: An In Vitro Study.

The aim of this study was to investigate and compare the leaching of four different clear aligner systems (Invisalign, Eon, SureSmile, and Clarity). Three sets of aligners as obtained from the four manufacturers were cut and immersed in glass vials containing ethanol with different solutions. The first was 100% ethanol, the second was 75% ethanol to 25% water, the third was 50% ethanol to water, the fourth was 25% ethanol to 75% water, and the last was 100% water.

The effect of dietary pigmentation on the esthetic appearance of clear orthodontic elastomeric modules.

Objective: To compare the stain resistance of three types of clear elastomeric modules exposed to several common dietary substances through the assessment of the perception of a group of dentists to discoloration using visual analog scale (VAS).

Materials And Methods: Elastomeric modules from Unitek (AU), Ormco (OR), and dentaurum (DE) were immersed in the following food substances: Coffee, black tea, chocolate, energy drink, ketchup, and Coca-Cola for 72 h. VAS was used to reflect the module staining severity.
