Research summary
Orthodontics and quality of life
In recent years, outcomes of health care are increasingly seen in the medical literature. Orthodontics is a branch of dentistry concerned primarily with the correction of dental crowding or tooth malalignment. Orthodontic treatment is undertaken on the basis of improving oral health related quality of life. Studies have demonstrated that there are not only aesthetic but psychosocial benefits of orthodontic treatment (Cunningham and Hunt, 2001).
Evaluating Orthodontic Treatment – occlusal indices
In orthodontics, achieving optimum alignment and occlusion is paramount. The improvement in occlusal characteristics can be objectively assessed by using an occlusal index that compares the occlusion before and after treatment to determine whether a worthwhile improvement has been achieved following treatment. Various indices have been developed to determine severity and complexity of malocclusion, treatment need, or improvement change during treatment to be defined for an individual or population.
Peer Assessment Rating Index
One of the most commonly used occlusal indices is the Peer Assessment Rating (PAR), which was introduced by Richmond and colleagues (Richmond et al., 1992). It has been shown to be a valid and reproducible index (Richmond et al., 1992; DeGuzman et al., 1995; Firestone et al., 2002). PAR uses study casts to score maxillary and mandibular anterior alignment, buccal segment occlusion, overjet, overbite, and centreline discrepancies. When pre- and post-treatment models are evaluated, the improvement achieved during treatment can be expressed as a percentage of change (Richmond et al., 1992). PAR is also a key performance indicator for orthodontic treatment outcomes in NHS primary and secondary care however it does not take into consideration patient reported outcomes measures particularly patient satisfaction.
We propose to investigate if there are associations between orthodontic occlusal outcomes using the peer assessment rating and patient satisfaction.
