Abstract Objective: To compare the periodontal status of adults treated with fixed buccal orthodontic appliances vs removable orthodontic aligners over 1 year of active therapy. Materials and Methods: The study population consisted of 42 subjects; 22 treated with fixed buccal orthodontic appliances and 20 treated with removable aligners. Clinical indices recorded included: plaque index (PI), gingival index (GI), bleeding on probing (BOP), and probing pocket depth (PPD). Plaque samples were assessed for hydrolysis of N-benzoyl-DL-arginine-naphthylamide (BANA test). Indices and BANA scores were recorded before treatment and at 6 weeks, 6 months, and 12 months after initiation of orthodontic therapy. Results: After 6 weeks, only mean PPD was greater in the fixed buccal orthodontic appliance group. However, after 6 months, the fixed buccal orthodontic appliance group had significantly greater mean PI, PPD, and GI scores and was 5.739 times more likely to have a higher BANA score. After 12 months, the fixed buccal orthodontic appliance group continued to have greater mean PI, GI, and PPD, while a trend was noted for higher BANA scores and BOP. Conclusions: These results suggest treatment with fixed buccal orthodontic appliances is associated with decreased periodontal status and increased levels of periodontopathic bacteria when compared to treatment with removable aligners over the 12-month study duration.

Abstract Objective: To evaluate the effectiveness of interventions on accelerating orthodontic tooth movement. Materials and Methods: We searched the databases of PubMed, Embase, Science Citation Index, CENTRAL, and SIGLE from January 1990 to August 2011 for randomized or quasi-randomized controlled trials that assessed the effectiveness of interventions on accelerating orthodontic tooth movement. The processes of study search, selection, and quality assessment were conducted independently in ... [Abstract] [Full-text]

Abstract Objective: To evaluate the expression of an activator of nuclear factor-kappa (RANK), osteoprotegerin (OPG), osteopontin (OPN), and transforming growth factor ß1 (TGF-ß1) in gingival crevicular fluid (GCF) of teeth subjected to orthodontic forces. Materials and Methods: A randomized, pilot clinical trial including 10 healthy volunteers was conducted using a split-mouth design. Orthodontic elastic separators were placed between the second premolar and first molar, with the ... [Abstract] [Full-text]

Implant site development by orthodontic forced eruption of nontreatable teeth: a case report. Open Dent J, 6: 99-104.
This study aimed to evaluate the in vivo remineralization of acid-etched enamel in non-brushing areas as influenced by fluoridated orthodontic adhesive and toothpaste. One hundred and twenty teeth from 30 volunteers were selected. The teeth were assigned to four treatments: no treatment (negative control); 37% phosphoric acid-etching (PAE) (positive control); PAE + resin-modified glass ionomer cement (RMGIC); and, PAE + composite resin. Patients brushed teeth with fluoridated (n = 15) or ... [Abstract] [Full-text]

Bone anchor systems for orthodontic application: a systematic review. Int J Oral Maxillofac Surg.
This systematic review was performed to investigate the usefulness and clinical effectiveness of skeletal anchorage devices to determine the most effective bone anchor system for orthodontic tooth movement. Literature on bone anchorage devices was selected from PubMed and the Cochrane Library from January 1966 to June 2010. 55 publications regarding miniplates, miniscrews, palatal implants and dental implants as orthodontic anchorage were identified for further analysis. All bone anchorage ... [Abstract] [Full-text]
Satisfaction with orthodontic treatment. Angle Orthod.
Abstract Objectives: To examine the satisfaction of patients with their orthodontic treatment at the Department of Orthodontics at the Academic Centre for Dentistry Amsterdam (ACTA) in the Netherlands. Materials and Methods: To analyze differences in satisfaction through time, the results of patients treated at ACTA in 2008 and 2009 were compared with the results of patients treated at ACTA in 2000. A validated questionnaire about patient satisfaction was used. The total scale was divided into ... [Abstract] [Full-text]

Prevention and management of accidental foreign body ingestion and aspiration in orthodontic practice. Ther Clin Risk Manag, 8: 245-52.
Among the myriad emergencies that could arise in the dental clinical setting there are a few that occur occasionally despite being entirely preventable. Ingestion or aspiration of dental materials, appliances, or instruments comprises this category. Regardless of incidence, foreign body ingestion or aspiration episodes are recognized as potential complications in the specialty of orthodontics. Despite their infrequent occurrence, the morbidity from a single incident and the amount of specialty ... [Abstract] [Full-text]
