BACKGROUND Studies have shown conflicting results on the association between nickel exposure from orthodontic appliances and nickel sensitization. OBJECTIVES & METHOD: In a cross-sectional study, we investigated the association between nickel sensitization and exposure to orthodontic appliances and piercings. 4376 adolescents were patch tested following a questionnaire asking for earlier pierci...

The aim of the study was to investigate the periodontal and microbiological status of patient undergoing fixed orthodontic treatment. Methods: In this study, plaque samples were collected from 12 patients at baseline, four monthly visits during orthodontic treatment and at 30 days after removal of the appliance. A benzoyl-DL-arginine-naphthylamide (BANA) test was performed to identify the perio...

Purpose. As documented in the literature, bony defects can be managed by an orthodontic approach. Methods. This case report describes the treatment of a bony defect caused by orthodontic malposition through phase I periodontal therapy and a simple removable orthodontic appliance used for the first time in a 20-year-old girl. Results. The periodontal pocket was reduced from 8 mm to 3 mm shortly ...

Background and Aim: The aim of the present study was to evaluate the cephalometric changes in Class II division 1 mandibular deficient patients treated with Farmand functional appliance.  Methods and Materials: Twenty-seven subjects (17 girls and 10 boys) with the mean age of 11.1±1.4 years were involved in the present study. All the subjects were treated with Farmand functional ...

Objectives: The aim of this study was to investigate the effect of orthodontic loading on the expression of interleukin-1 (IL-1) and tumor necrosis factor- (TNF-) in compressed gingiva. Materials and Methods: Twenty-four male Wistar rats were used with four rats as controls at day 0. In ten rats, corticotomy was performed on either left or right side and the remaining side was served as con...

OBJECTIVES The aim of this study was to determine the occlusal bite force (OBF) changes, at the incisal and molar regions, after orthodontic treatment with functional appliance therapy in preadolescent subjects. MATERIALS AND METHODS OBF was measured for patients (17 females and 16 males) before and after the treatment with Andresen functional appliance for an average period of 9 months (mean...

Objectives: To assess and compare the change in pharyngeal airway dimensions hyoid bone position also to evaluate skeletal dental effects of Forsus Powerscope appliance Class II malocclusion patients with obstructive sleep apnea subjected 6 months fixed functional therapy. Methods: 30 class having day-time somnolence associated snoring requiring orthodontic treatment were selected randomly divi...

External apical root resorption is an iatrogenic consequence of orthodontic treatment, although it may also occur in the absence of orthodontic treatment. Root resorption causes root shortening and breaks the integrity of teeth arch and this is very important for successful orthodontic treatment. Orthodontics is probably the only dental specialty that actually uses the inflammatory process as a...

Aesthetic improvement is highly valued by patients seeking orthodontic treatment ( Dann et al. , 1995 ). Subjects with a Class II malocclusion are a good example of patients who are referred to orthodontists primarily for aesthetic improvement ( Dann et al. , 1995 ). In growing patients, two-phase treatment of Class II skeletal malocclusions, which includes growth modifi cation with functional ...

Global increase in patients seeking orthodontic treatment creates a demand for the use of acrylic resins in removable appliances and retainers. Orthodontic removable appliance wearers have a higher risk of oral infections that are caused by the formation of bacterial and fungal biofilms on the appliance surface. Here, we present the synthetic route for an antibacterial and antifungal organicall...
