Perception of pain in Class II malocclusion children treated with cervical headgear: a randomized controlled trial.

Objectives: The aims of this study were: 1. to evaluate the experience of pain perceived by children during separator placement and headgear wear; 2. to find possible associations between the perceived intensity of pain and the levels of Substance P (SP) and interleukin-1 beta (IL-1β) in the gingival crevicular fluid (GCF) during these procedures; 3.

Headgear compliance as assessed by a temperature-sensitive recording device: a prospective clinical study.

Objective: To accurately describe compliance in headgear wearing time by using a temperature- and force-sensitive device over an 8 month period of use in a prospective clinical manner.

Materials And Methods: Twenty children with Class II malocclusion aged 8-12 years were randomly selected for treatment with cervical headgear. The headgears were equipped with an electronic module, which measured temperature and force, and patients were instructed to wear the headgear 12 hours daily.
