Orthodontic management of uneven gingival margins in patients with healthy or reduced periodontium to improve smile aesthetics

Periodontology 2000, EarlyView.
Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'

Periodontal and orthodontic management of impacted canines

Periodontology 2000, EarlyView.
Abstract The maxillary and mandibular canines are described by many clinicians as the “cornerstone” of the arch. When in their optimal position, they play a critical role in providing a well‐balanced occlusal scheme that contributes toward functional as well as neuromuscular stability, harmony, esthetics, and dentofacial balance.

Tissue reaction to orthodontic adhesives

American Journal of Orthodontics, 1982
The widespread introduction of materials for direct bonding into practices and the numerous reports of a variety of toxic reactions to similar materials prompted a study of the toxicity of six adhesives in an animal model. Thirty-nine hamsters were employed to evaluate responses of skin, oral mucosa, and gingiva, sites of possible contamination by ...

A review of orthodontic cements and adhesives

American Journal of Orthodontics and Dentofacial Orthopedics, 2001
Dental cements and resins are used intraorally to secure fixed orthodontic devices. Although cements are still used, the popularity of resin and resin-cement hybrid materials is increasing because of their improved physical properties and low solubility in oral fluids.

Orthodontic adhesives and bond strengthtesting

Seminars in Orthodontics, 1997
A bracket bond failure is a frustrating occurrence in orthodontic practice. Because the location of the bond failure may indicate the probable cause, it is important to understand the significance of "bond strength" in a clinical application. Bonding in orthodontics can be studied using controlled clinical models or in vitro using simulated clinical ...

Microbial attack of orthodontic adhesives

American Journal of Orthodontics and Dentofacial Orthopedics, 1995
Composites used as orthodontic direct bonding adhesives have a polymeric matrix that can host and nurture a variety of aerobic and anaerobic microorganisms acting alone or in combination (consortia). Their accumulation can lead to the weakening of the bond and possibly the attacking of the tooth.

Antibacterial and Remineralizing Fillers in Experimental Orthodontic Adhesives [PDF]

Materials, 2019
Orthodontic adhesives with antimicrobial and remineralizing properties may be an alternative to control white spot lesions around brackets. The aim of this study is to develop an experimental orthodontic adhesive containing boron nitride nanotubes (BNNT) and alkyl trimethyl ammonium bromide (ATAB). Methacrylate (BisGMA and TEGDMA) monomers were used to
