American Board of Orthodontics: Progress of the scenario-based clinical examination.

Am J Orthod Dentofacial Orthop 2020 Jul;158(1):14-15

American Board of Orthodontics, St Louis, Mo.

In 2017, the directors of the American Board of Orthodontics (ABO) decided to move forward with a new clinical examination format-a scenario-based examination. The first examination of this type was administered in February 2019, and 2 more exams have been given since then. Each examination consisted of at least 6 scenarios with 4-7 questions for each scenario. Read More

Correction of bilateral heavily impacted second molar with improved super-elastic nickel-titanium alloy wires.

Am J Orthod Dentofacial Orthop 2020 Jul;158(1):114-125

Department of Orthodontic Sciences, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan.

Impaction and an abnormal eruption of a second molar occur because of a lack of retromolar space, premature eruption of the mandibular third molar, and ankyloses. The prognosis must be carefully considered when extracting a damaged permanent tooth. In addition to extraction for orthodontics, this enables the establishment of an effective force system to align the impacted tooth. Read More

Evaluation of titanium dioxide coating on surface roughness of nickel-titanium archwires and its influence on Streptococcus mutans adhesion and enamel mineralization: A prospective clinical study.

Am J Orthod Dentofacial Orthop 2020 Jun 20. Epub 2020 Jun 20.

Department of Orthodontics and Dentofacial Orthopedics, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India.

Introduction: This research aimed to evaluate the effect of titanium dioxide (TiO) coating on surface roughness (R) of nickel-titanium (NiTi) archwires and its influence on Streptococcus mutans (S mutans) adhesion and enamel mineralization at the end of 1 month in orthodontic patients and to evaluate the integrity of the TiO coating.

Methods: Twelve patients undergoing orthodontic treatment with preadjusted edgewise appliance formed the sample for this prospective clinical study. Uncoated NiTi archwires and TiO nanoparticle coated NiTi archwires in as-received condition and after 1 month of intraoral use were subjected to R analysis using surface profilometry, and surface topography using scanning electron microscopy.

Maxillary molar intrusion and transverse decompensation to enable mandibular single-jaw surgery with rotational setback and transverse shift for a patient with mandibular prognathism and asymmetry.

Am J Orthod Dentofacial Orthop 2020 Jun;157(6):818-831

Postgraduate Orthodontic Program, Arizona School of Dentistry & Oral Health, A.T. Still University, Mesa, Ariz; Graduate School of Dentistry, Kyung Hee University, Seoul and Seoul, Korea.

When performing single-jaw surgery for mandibular setback, the distal segment of the mandible is brought distally along the occlusal plane, leaving the relationship of the B-point and pogonion unchanged. Double-jaw surgery for rotation of the maxillomandibular complex can be considered for solving this problem. However, maxillary surgery for rotational setback of the mandible can be replaced with orthodontic intrusion of the maxillary molars. Read More

A cone-beam computed tomographic assessment of the proximity of the maxillary canine and posterior teeth to the maxillary sinus floor: Lessons from 4778 roots.

Am J Orthod Dentofacial Orthop 2020 Jun;157(6):792-802

Department of Orthodontic Science, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan.

Do malocclusion and orthodontic treatment impact oral health? A systematic review and meta-analysis.

Am J Orthod Dentofacial Orthop 2020 Jun;157(6):738-744.e10

Faculty of Dentistry, Department of Preventive and Public Dentistry, Rio de Janeiro State University, Rio de Janeiro, Brazil.

Introduction: Currently, there is limited evidence on the effects of malocclusion on oral health and whether the correction of malocclusion results in an improvement in oral health. In this review, we examined the evidence from randomized controlled trials and prospective cohort studies to provide information on any association between malocclusion and oral health and the effects of orthodontic treatment.

Methods: We conducted this review in 2 parts: (1) we looked at the impact of malocclusion on oral health, and (2) we reviewed the evidence on the effect of orthodontic treatment on oral health. Read More

The public perception of the differences between specialist orthodontists and general dentists: A comparison between Australia and Sweden.

Am J Orthod Dentofacial Orthop 2020 Jul 27;158(1):68-74. Epub 2020 May 27.

Faculty of Medicine and Health, Department of Orthodontics, Discipline of Orthodontics and Paediatric Dentistry, School of Dentistry, University of Sydney, Sydney Dental Hospital, Sydney Local Health District, Sydney, New South Wales, Australia.

Introduction: In Australia and Sweden, orthodontic treatments may be performed by either a general dental practitioner (GDP) or a specialist orthodontist. Evidence suggests that the public may easily confuse a GDP who provides orthodontic treatment with a specialist orthodontist. We conducted a survey of people in Australia and Sweden to assess their understanding of the differences between a specialist orthodontist and a GDP who provides orthodontic treatments. Read More

Incidental findings of posterior arch defects of the atlas in orthodontic patients: A case series.

Am J Orthod Dentofacial Orthop 2020 Jul 21;158(1):35-39. Epub 2020 May 21.

Division of Oral and Maxillofacial Radiology, University of Florida College of Dentistry, Gainesville, Fla.

Introduction: Congenital defects of the posterior arch of atlas are uncommon anomalies that may go unnoticed. Radiographs and cone-beam computed tomography scans made for orthodontic purposes often show the atlas; therefore, these rare defects might first be noted as incidental findings on orthodontic records.

Methods: A series of 7 cases of posterior arch defects of atlas (C1) that were detected during routine radiographic examination are presented here. Read More

Introduction: The purpose of this study was to evaluate the ability of a publicly available facial recognition application program interface to calculate similarity scores for presurgical and postsurgical photographs of patients who underwent orthognathic surgeries. Our primary objective was to identify which surgical procedure(s) had the greatest effect(s) on the similarity score.

Methods: Existing photographs for 25 orthodontic-orthognathic patients were analyzed using the application program interface to calculate similarity scores between the presurgical and postsurgical photographs. Read More

Caries lesions can result in long-term esthetic disturbance, costly interventions, and even interrupted treatment. Therefore, it is crucial to assess accurately both a patient's caries risk before treatment and their suitability for orthodontic treatment. Read More
