Hearing Function Moderates Age-Related Differences in Brain Morphometry in the HCP Aging Cohort.

There are well-established relationships between aging and neurodegenerative changes, and between aging and hearing loss. The goal of this study was to determine how structural brain aging is influenced by hearing loss. Human Connectome Project Aging data were analyzed, including T1-weighted Magnetic Resonance Imaging (MRI) and Words in noise (WIN) thresholds (n = 623).

Hearing function moderates age-related changes in brain morphometry in the HCP Aging cohort.

Introduction: There are well-established relationships between aging and neurodegenerative changes, and between aging and hearing loss. The goal of this study was to determine how structural brain aging is influenced by hearing loss.

Methods: Human Connectome Project Aging (HCP-A) data were analyzed, including T1-weighted MRI and Words in Noise (WIN) thresholds (n=623).

Assessment of orthodontic borderline treatment need: A comparison of two aesthetic indices.

Objective: To compare a new "guide for borderline orthodontic need" (GBON) with the "aesthetic component" (AC) of the IOTN in assessing borderline cases (dental health component DHC 3), and to compare reliability and opinions of orthodontists on the use of each index.

Materials And Methods: Cross-sectional population descriptive study. Ninety-four qualified orthodontists assessed 30 borderline malocclusions according to the GBON and AC indices and completed a questionnaire.

The development of a guide to borderline orthodontic need.

Objective: To produce a guide for dentists and orthodontists to determine orthodontic treatment need in borderline cases (dental health component DHC 3) and to compare views of different panels of judges on treatment need.

Materials And Methods: Prospective, observational study. Photographs of one hundred subjects displaying borderline occlusal traits (DHC3) were collected.

Bonded orthodontic retention: a practical guide.

Bonded retainers may play an important role in reducing unwanted tooth movements following orthodontic treatment, with an open-ended perspective on retention now established. The importance of planning for bonded retention is emphasised, with key principles in minimising failure rates as well as wire and adhesive options discussed. Approaches to preparation of the wire and the teeth, the bonding process, as well as variations in retainer design, and means of preventing problems and undertaking repairs in order to achieve predictable fixed retention in the long term are also outlined.

Orthodontic retention patterns in the United Kingdom.

Objective: To determine whether retention patterns in the UK are influenced by operator gender, age or sphere of practice.

Design: Postal self-completed questionnaire.

Settings: Private practice, NHS practice, hospital practice and community practice.
