Introdouction: According to the importance of enamel discoloration and controversy regarding the effect of different orthodontic bonding materials on tooth discoloration, the aim of this study was to determine enamel discoloration following orthodontic brackets using different bonding materials. Materials and methods: This in-vitro study, 30 recently extracted human premolars with inta...

Aim: Orthodontic brackets during their wear cause demineralization of enamel, which is the initial step in caries development. The prevention such spots crucial to ensure healthy teeth, but patients’ compliance not most optimal way. aim this study was compare antimicrobial properties fluoride-containing orthodontic materials without additional fluoride. Materials and Methods: Antibacterial effe...

This in vitro study was undertaken to evaluate the caries-preventive effect of three orthodontic band cements (a dual-curing resinmodified glass ionomer cement [RMGIC] and two light-curing polyacid-modified composite resin [compomer] cements) in terms of fluoride release, retentiveness, and microleakage after thermocycling. The RMGIC (Ortholy Band Paste [GC Ortholy, Inc., Tokyo, Japan]) showed ...

OBJECTIVE This in vitro study aimed to compare the microleakage of orthodontic brackets between enamel-adhesive and adhesive-bracket interfaces at the occlusal and gingival margins bonded with different adhesive systems. MATERIALS AND METHODS A total of 144 human maxillary premolar teeth extracted for orthodontic reasons was randomly divided into four groups. Each group was then further divid...

Background: This was aimed to investigate the effect of surface treatment with different primers on shear bond strength (SBS) between metallic brackets and monolithic zirconia crowns.Methods: Sixty-five molar crowns were fabricated CAD-CAM technology. All underwent thermal cycling. After aging, randomly divided into five groups (n = 13) according cementation procedures: orthodontic bonding syst...

Objectives: The objectives of the study were to assess white spot lesions around orthodontic bracket macroscopically using two different bonding agents – one with amorphous calcium phosphate (ACP) (Aegis Ortho) and without ACP (Transbond XT). Materials Methods: comprises 10 patients from 14 23 years age. Patients divided into control groups. Forty premolar teeth then observed (20 in each group)...

abstract statement of problem: the viscosity of orthodontics adhesive primers is crucial for stability and correct brackets ‘position during bond up. an excessive adhesive flow during brackets seating could change the brackets’ position. objectives: the main purpose of this study was to investigate the viscosity of four orthodontic adhesive primers in two different temperatures. materials and m...

The aims of this study were to evaluate the shear bond strength (SBS), fracture mode, and wire pull out (WPO) resistance between resin-modified glass ionomer cement (RMGIC) and conventional orthodontic composite used as a lingual retainer adhesive. Forty lower human incisors were randomly divided into two equal groups. To determine the SBS, either Transbond-LR or Fuji Ortho-LC was applied to th...
