Photodiagnosis and Photodynamic Therapy, 2020
BACKGROUND Potential complications during fixed orthodontic procedures are white spot lesions (WSLs) and tooth decay. This study evaluated the anti-biofilm activity of an orthodontic adhesive (OA) incorporating curcumin (Cur) doped Poly lactic-co-glycolic

Numerical investigation of fixed orthodontic brackets
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2000This paper presents the results of investigations into the mechanical behaviour of fixed orthodontic brackets. Special attention has been paid to the detailed modelling of the interface between the bracket base and an adhesive by which attachment is made to the tooth surface.

Torsional creep of polycarbonate orthodontic brackets
Dental Materials, 1997Polycarbonate materials are known to exhibit creep. The purpose of this study was to investigate torsional creep of polycarbonate orthodontic brackets.Four polycarbonate, one metal, and one ceramic brackets were tested. An in vitro torque apparatus was constructed which applied 2000 g-mm of torque to the bracket slot via a cantilever beam perpendicular

Material testing of reconditioned orthodontic brackets
Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2012While all manufacturers of orthodontic brackets label these products for single use, there are commercial providers offering bracket reconditioning (or "recycling"). We conducted this study to investigate the effects of different recycling techniques on material-related parameters in orthodontic brackets, aiming to derive indications for clinical use ...

Adherence of Streptococcus mutans to orthodontic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1998The affinity of Streptococcus mutans to orthodontic brackets made from metal, plastic, and ceramic was tested. Twelve saliva-coated brackets and 12 noncoated brackets of each type were immersed in a S. mutans solution labeled with [3H] thymidine. Each sample was then immersed in distilled water at 20 degrees C for 24, 48, and 72 hours to measure the ...

Retention capacity of the bracket bases of new esthetic orthodontic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1995Tensile bond strength and bond failure locations were evaluated in vitro for three types of direct bonding cements (self-cured diacrylate, dual-cured diacrylate, and dual-cured glass ionomer) with four types of brackets (stainless steel, polycarbonate, ceramic, and ceramic-polycarbonate) by using a plastic cylinder as the substrate.

Corrosion of resin-bonded orthodontic brackets
American Journal of Orthodontics, 1982The objective was to identify the nature and origin of indelible black and green stains found in enamel after the removal of bonded orthodontic brackets. Several brackets were examined by scanning electron microscopy and energy-dispersive x-ray analysis. Irrespective of the type of bracket or resin, morphologic evidence of corrosion activity was found.

Orthodontic Treatment with Lingually Bonded Brackets
British Journal of Orthodontics, 1984The direct bonding of orthodontic brackets to enamel has greatly improved the aesthetics of fixed appliance orthodontics. A recent development has been the lingual placement of the attachments Which has resulted in none of the mechanics being visible on the anterior teeth.

Aesthetic orthodontic brackets.
Journal of orthodontics, 2005Due to an increasing demand for superior aesthetics during fixed appliance treatment, the use of aesthetic brackets has grown in popularity over recent years. Although often requested by patients, aesthetic brackets are not without their disadvantages.
