Introduction: Orthodontist must take precautionary measures to protect patients from cross-infection by contaminated materials received the manufacturers. To minimize incidence of prior bonding an invitro study was done assess antibacterial activity chlorhexidine, povidone iodine and glutaraldehyde. Aim: compare 2% 5% glutaraldehyde on orthodontic bonding. Materials methods: A total 36 samples ...

Nickel-titanium archwires in orthodontic wires have nickel ion releases. The use toothpaste and saliva immersion time may cause its This study aims to prove the difference interaction between variations towards amount of releases at nickel-titanium archwires. was an experimental research with a post-test only control group design. Twenty seven were divided into three groups, i.e., K group, whic...

Aim and objectives: To determine the impact on mechanical properties surface features of ceramic-coated nickel-titanium (CC-Ni-Ti) archwires when subjected to charcoal, probiotic, chlorhexidine mouthwashes in vitro conditions. Materials methods: Eighty samples 25 mm were cut from posterior end preformed maxillary 0.016’’ CC-Ni-Ti super elastic (Koden Company, USA) distributed into four equal gr...

BACKGROUND The purpose of this study was to assess the surface characterization and frictional resistance between stainless steel brackets and two types of orthodontic wires made of stainless steel and nickel-titanium alloys after immersion in a chlorhexidine-containing prophylactic agent. METHODS Stainless steel orthodontic brackets with either stainless steel (SS) or heat-activated nickel-t...

The eruption of the second molars may delay therapy and lengthen treatment time. To minimize excessive prolongation, principle resistance factor elimination was applied to unerupted lower molar through a surgical incision on occlusal gingival tissue. 3.7 successfully erupted easily bonded following month, allow archwires sequence.

Occlusal plane canting could be a challenge for orthodontists due to complexity of mechanics and uncertainity treatment. Earlier, before advent TADS in orthodontics, was treated by complex using elastics, asymmetric bends archwires, bite blocks, high pull headgears, orthognathic surgeries etc. With TADs, its become easier treat occlusal even some severe cases. The present case report illustrate...

Orthodontic mechanotherapy encompasses the use of several archwires during speci c stages of treatment. Metallic orthodontic appliances consist of bands, arch wires, ligature wires, hooks, tubes, brackets, and springs are daily used in orthodontic practices for the correction of malocclusions in patients ( Oh et al. , 2004 ; Verstrynge et al. , 2006 ; Sabane et al. , 2009 ). One of the most im...

BACKGROUND Technological advances in wire selection and bracket design have led to improved treatment efficiency and allowed longer time intervals between appliance adjustments. The wires remain in the mouth for a longer duration and are subjected to electrochemical reactions, mechanical forces of mastication and generalized wear. These cause different types of corrosion. This study was done to...
