Controlled, prospective trial of psychosocial function before and after mandibular advancement splint therapy.

Introduction: The aim of the study was to investigate psychosocial function in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS), before and after mandibular advancement splint (MAS) therapy.

Methods: In a prospective, parallel-group study, changes in psychosocial scores were compared before and after MAS therapy for OSAHS. Patients from the top (MAS treated, n = 40) or bottom (conservatively treated n = 35) of a MAS waiting list rated quality of life (Short Form 36 [SF-36] Health Survey) and sleepiness (Epworth Sleepiness Scale [ESS]).

The use of videofluoroscopy in the assessment of the pharyngeal airway in obstructive sleep apnoea.

This prospective cohort study evaluated the use of videofluoroscopy in assessing changes in both antero-posterior (A-P) and transverse pharyngeal airway dimensions in patients with obstructive sleep apnoea (OSA). Forty patients [32 males and 8 females; mean age of 49.3 (SD = 10.

Influence of supplemental written information on adolescent anxiety, motivation and compliance in early orthodontic treatment.

Objectives: To test the null hypotheses that supplementation of verbal information with written information when obtaining consent to orthodontic treatment has no effect on (1) anxiety, motivation and apprehension related to treatment and (2) compliance in the early stages of fixed appliance therapy.

Materials And Methods: Seventy-six adolescents who were due to start fixed appliance therapy were randomly allocated to receive verbal information only or verbal and written information before orthodontic treatment. Participants' anxiety, motivation, and apprehension were assessed using a questionnaire that was completed prior to meeting the orthodontic clinician (T1), following consent to treatment (T2), and after 12 weeks of treatment (T3).

The relationship between craniofacial anatomy and obstructive sleep apnoea: a case-controlled study.

The aim of the study was to identify craniofacial and pharyngeal anatomical factors directly related to obstructive sleep apnoea (OSA). The design and setting was a hospital-based, case-controlled study. Ninety-nine subjects (78 males and 21 females) with a confirmed diagnosis of OSA, who were referred to the Dental Hospital for construction of a mandibular advancement splint were recruited.

Impact of sleep nasendoscopy on the outcome of mandibular advancement splint therapy in subjects with sleep-related breathing disorders.

Aim: To evaluate the impact of positive sleep nasendoscopy, with simultaneous mandibular advancement, on the outcome of mandibular advancement splint therapy in 120 subjects with sleep-related breathing disorders.

Methodology: Overnight polysomnography and sleep nasendoscopy were performed prior to splint therapy. Follow-up sleep studies, with the appliance in situ, were undertaken for those patients with obstructive sleep apnoea.
