Perception of discomfort by patients undergoing orthodontic treatment

Interleukin 1 beta and prostaglandin E are involved in the response of periodontal cells to mechanical stress in vivo and in vitro

TL;DR: It is demonstrated that periodontal ligament cells respond to mechanical stress by increased production of PGE, and that IL-1 beta enhances this response.
Journal Article

Open bite: a review of etiology and management.

Treatment response and long-term dentofacial adaptations to maxillary expansion and protraction.

TL;DR: Treatment with the protraction facemask is most effective in Class III patients with a retrusive maxilla and a hypodivergent growth pattern, and one should anticipate individual variations in treatment response and subsequent growth changes.
Journal ArticleDOI

Soft tissue and dentoskeletal profile changes associated with maxillary expansion and protraction headgear treatment
