Potential Impact of Long COVID-19 on Orthodontic Treatment.

Pooled estimates indicate about 226 million individuals are currently experiencing or have experienced persistent symptoms from COVID-19. Long COVID-19 (LC) has been associated with a prolonged inflammatory and stress responses in affected individuals. Due to common pathways, LC could impact the biological mechanisms of orthodontic tooth movement, orthodontically-induced inflammatory root resorption and periodontal tissue response of patients undergoing orthodontic treatment.

Learning Games: A New Tool for Orthodontic Education.

Learning games that are based on current scientific concepts are underutilized in dental education. This paper explores the relevant science of learning and discusses several principles that are conducive to learning and teaching in an educational setting, namely retrieval practice, feedback, motivation, and engagement. A discussion of learning games in health professional education ensues, followed by a description of relevant best practices in game design for learning.

Associations between Oral Health and Cannabis Use among Adolescents and Young Adults: Implications for Orthodontists.

Cannabis use is prevalent among adolescents and young adults in the US. Virtually all modes of cannabis consumption involve the oral cavity, and previous studies have linked cannabis use with poorer oral health. We sought to identify associations between cannabis use and various oral health outcomes and behaviors among individuals 12-25 years of age, and to discuss implications for orthodontists who largely interact with this age group over an extended period of treatment time.

Stress and anxiety in orthodontic residents during the coronavirus disease 2019 pandemic.

Introduction: The coronavirus disease 2019 pandemic has had far-reaching effects on health care providers and health professional students; however, little is known about the factors related to stress and anxiety levels, specifically among orthodontic residents during this time.

Methods: A 2-part questionnaire, which included modified stress and anxiety inventories, was disseminated electronically to U.S.

Should attendance for preclinical simulation and clinical education be mandatory?

Mandatory attendance, particularly in didactic settings, is a highly debated topic in higher education, including dental education. Within dental education, a large portion of education occurs in preclinical laboratories and clinical environments. There is little to no research on attendance in these settings in dental schools.

Non-thermal plasma treatment to enhance the adhesion between enamel surface and orthodontic bracket.

Background: Adhesion strength of orthodontic attachments to enamel should be within optimal range to resist occlusal forces and to allow debonding without enamel damage.

Objective: The present study compared the effect of non-thermal plasma (NTP) and conventional surface treatment on the adhesion strength of orthodontic bracket to enamel.

Methods: A total of 100 premolar teeth were allocated into 5 groups according to the bonding procedure followed: Group 1 (Etch, prime and composite adhesive); Group 2 (Prime and composite adhesive); Group 3 (Glass ionomer cement); Group 4 (NTP, prime and composite adhesive) and Group 5 (NTP and glass ionomer cement).

Therapeutic effect of localized vibration on alveolar bone of osteoporotic rats.

Objectives: Vibration, in the form of high frequency acceleration (HFA), stimulates alveolar bone formation under physiologic conditions and during healing after dental extractions. It is not known if HFA has an anabolic effect on osteoporotic alveolar bone. Our objective is to determine if HFA has a regenerative effect on osteoporotic alveolar bone.

Age-dependent biologic response to orthodontic forces.

Introduction: Orthodontic tooth movement results from increased inflammation and osteoclast activation. Since patients of all ages now routinely seek orthodontics treatment, we investigated whether age-dependent biologic responses to orthodontic force correlate with the rate of tooth movement.

Methods: We studied 18 healthy subjects, adolescents (11-14 years) and adults (21-45 years), with Class II Division 1 malocclusion requiring 4 first premolar extractions.

Effect of micro-osteoperforations on the rate of tooth movement.

Introduction: Our objectives were to study the effect of micro-osteoperforations on the rate of tooth movement and the expression of inflammatory markers.

Methods: Twenty adults with Class II Division 1 malocclusion were divided into control and experimental groups. The control group did not receive micro-osteoperforations, and the experimental group received micro-osteoperforations on 1 side of the maxilla.
