Have orthodontists changed their retention and follow-up protocols due to contemporary orthodontics? An online survey.

Background: With advancements in orthodontic technology, treatment durations have shortened, often concluding at earlier ages. This shift prompts scrutiny of contemporary retention and post-treatment protocols. The study aimed to assess current professional preferences, compare them against patient age and treatment duration, and investigate the potential impacts of reduced treatment times on professional protocols, particularly when treatment concludes before pubertal growth.

Does the composite attachment of clear aligners compromise the effectiveness of dental bleaching? An in vitro study.

Effectiveness and predictability of treatment with clear orthodontic aligners: A scoping review.

Introduction: In an ideal clinical setting, orthodontic therapy with clear aligners (CA) should improve the patients' initial malocclusion and must guarantee equivalence between the results predicted and those obtained clinically to be considered an effective treatment. Therefore, this scoping review aimed to identify the orthodontic literature concerning the effectiveness and predictability of CA treatments.

Methods: A systematic computerized search was performed in 3 databases: PubMed, Scopus, and Embase.
