Randomized controlled clinical trial of oral health-related quality of life in patients wearing conventional and self-ligating brackets

Abstract

ObjectiveThe aim of this randomized controlled clinical trial was to compare oral health-related quality of life (OHRQoL) of patients treated with conventional, active self-ligating (ASL), and passive self-ligating (PSL) brackets in different therapeutic phases.MethodsSixty patients (mean age 18.3 years; 29 males and 31 females) requiring orthodontic treatment were randomly and equally assigned to receive conventional (Victory Series), ASL (In-Ovation R), or PSL (Damon 3MX) brackets. OHRQoL was measured with a self-administered modified 16-item Malaysian version of the Oral Health Impact Profile for immediate (soon after the visit) and late (just before the subsequent visit) assessments of the bonding and activation phases. Data were analyzed with the Kruskal-Wallis and chi-square tests.ResultsThe PSL and ASL groups showed more immediate and late impacts in the bonding phase, respectively; the conventional group was affected in both the assessments. The first activation phase had similar impacts in the groups. After the second activation, the conventional group showed more immediate impacts, whereas the PSL and ASL groups had more late impacts. The commonly affected domains were "physical disability," "functional limitation," "physical pain," and "psychological discomfort." No significant differences in the prevalence and severity of immediate and late impacts on OHRQoL of the patients were noted in any therapeutic phase.ConclusionsNo bracket system seems to ensure superior OHRQoL. This information could be useful for explaining the therapeutic phases, especially the initial one, and selecting the optimal bracket system based on the patient's preference.

Effects of self‐ligating brackets on oral hygiene and discomfort: a systematic review and meta‐analysis of randomized controlled clinical trials

“…Nine studies described the oral conditions of orthodontic patients treated with SLBs and CBs . Five of them reported plaque index scores and were included in meta‐analysis except one [11] from which data were unavailable.…”

“…However, they could not be synthesized in the meta‐analysis due to methodologic differences. One 3‐arm paralleled RCT comparing the oral health‐related quality of life in patients wearing ASLBs, PSLBs or CBs concludes that no bracket system seems to be superior . One study comparing microbiological parameters between PSLB and CB also concludes bracket design does not impact periodontal hygiene .…”

“…Additionally, only a few studies pay attention to the bacterial aggregation and oral hygiene of SLBs compared with CBs. Some researchers declare SLBs could reduce bacterial retention so as to improve oral hygiene, while others disagree . So far, there is no meta‐analysis trying to make a conclusion by reviewing these studies.…”

Temporary deterioration of oral health–related quality of life (OHRQoL) in nonextraction and extraction modalities of comprehensive orthodontic treatment in adolescents

“…Awareness of how facial appearance affects quality of life (QoL) has rapidly increased the demand for orthodontic treatment. 1 The motivating factors for undergoing orthodontic treatment are enhanced dental and facial esthetics and, consequently, minimized psychosocial problems, which contribute to QoL. 2,3 Many studies [4][5][6][7] have explored the physical, social, or psychological effects of orthodontic treatment and how discomfort and pain affect these aspects of QoL.…”

Impact of wearing fixed orthodontic appliances on quality of life among adolescents: Case-control study

“…3,4,[6][7][8] A number of studies have addressed experiences of discomfort and pain before and after the placement of orthodontic appliances, as well as in different phases of treatment. 4,[7][8][9] Other studies have assessed the dental and social impacts of wearing orthodontic appliances. 3,6 Changes in OHRQoL attributed to orthodontic treatment have been measured in longitudinal studies involving Chinese adolescents.…”
