The purpose of this study was to investigate the effect of orthodontic treatment on oral health-related quality of life (OHRQoL) in groups of standard patients with severe malocclusions; cleft lip, cleft palate, or cleft lip and palate patients; and orthognathic surgery patients.
The study sample consisted of 83 consecutive patients undergoing treatment at the orthodontic unit of Christchurch Hospital, Christchurch, New Zealand, divided into 3 groups: 30 adolescents with severe malocclusions; 24 adolescents with cleft lip, cleft palate, or cleft lip and palate; and 29 adults with severe skeletal discrepancies requiring both orthognathic surgery and orthodontic treatment. Each patient completed the Short Form of the Oral Health Impact Profile (OHIP-14) questionnaire before and after orthodontic treatment.
The baseline OHIP-14 subscale scores among the 3 study groups were significantly different, with the surgery patients having nearly twice the OHIP-14 scores of the other 2 groups for nearly half of the items (P <0.05). The surgery patients experienced the greatest reduction in OHIP-14 scores (ie, improvement in OHRQoL), with the largest effect sizes reported for the psychological discomfort (+2.73) and disability (+2.65) domains. The group with clefts experienced the smallest changes in OHIP-14 scores across all 7 domains (-0.03 to +0.63). After adjusting for age and sex, the surgical patients had a significantly greater reduction in pretreatment OHIP-14 scores than did the standard and the cleft patients (P <0.01).
The effect of orthodontic treatment on OHRQoL varies for different patient groups even after adjusting for age and sex. The greatest improvement in OHRQoL occurred in adults with a need for orthognathic surgery, whereas the least improvement seemed to occur in adolescents with cleft lip, cleft palate, or cleft lip and palate.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 July 2017.
All research outputs
#12,358,651
of 34,410,315 outputs
Outputs from American Journal of Orthodontics & Dentofacial Orthopedics
#608
of 2,195 outputs
Outputs of similar age
#117,068
of 311,962 outputs
Outputs of similar age from American Journal of Orthodontics & Dentofacial Orthopedics
#4
of 45 outputs
Altmetric has tracked 34,410,315 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,195 research outputs from this source. They receive a mean Attention Score of 4.4. This one is in the 38th percentile – i.e., 38% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 311,962 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 45 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 86% of its contemporaries.
