Orthodontic treatment need, the types of brackets and the oral health-related quality of life

Abstract

Background. Malocclusion can affect the oral health-related quality of life (OHRQoL). The influence of the orthodontic treatment need (OTN) and the type of brackets on OHRQOL is not clear. Objectives.The aim of the present study was to determine the relationships between OTN and the bracket type and OHRQoL during the first 6 months of orthodontic treatment (OT) in adult patients.Material and methods. This cohort study was conducted at the Department of Orthodontics of a private university. A total of 216 patients aged ≥18 years participated in the study (106 patients with conventional brackets and 110 with self-ligating brackets). The OHRQoL was evaluated using the 14-item Oral Health Impact Profile (OHIP-14) at 5 time points -before OT (T0), and at 24/48 h (T1), 1 month (T2), 3 months (T3), and 6 months (T4) after the installation of the orthodontic appliance. The OTN was evaluated with the dental aesthetic index (DAI) by 2 previously calibrated operators. For the statistical analysis, the χ 2 test and the Mann-Whitney U test were used. Additionally, Poisson regression models were performed.Results. The evidence of an association between OHRQoL and OTN was found only at T3 (p = 0.0095). No association was found between OHRQoL and the bracket type. However, in the regression models, OHRQoL was statistically significantly worse at T3 in the group with a greater OTN (IRR (incidence rate ratio) = 1.34; 95% CI (confidence interval): 1.21;1.48) and at T4 in the self-ligation group (IRR = 1.23; 95% CI: 1.12;1.36). Conclusions.The OHRQoL was affected in the same way at the beginning of OT, regardless of OTN and the bracket type used. However, a worse OHRQoL was observed at 3 months in subjects with greater OTN and at 6 months in patients with self-ligating brackets.

A longitudinal pilot study examining the influence of the orthodontic system chosen in adult patients (brackets versus aligners) on oral health-related quality of life and anxiety

“…Orthodontic treatment can significantly improve patients’ OHRQoL [ 19 , 23 , 24 , 29 ]. In this study, in the total sample, it was observed that at one month after starting treatment, the patients’ OHRQoL was worse than at the beginning.…”

Does hormone replacement therapy impact implant osseointegration in females- A systematic review and meta-analysis

“…Another crucial area affected by HRT is bone health ( Vermesan et al, 2015 , Henes and Hübner, 2020 ). Estrogen has been found to have a protective effect on blood vessels and can help maintain cardiovascular health in premenopausal women ( “The 2022 Hormone Therapy Position Statement of The North American Menopause Society”, 2022; Barrera-Chaparro et al, 2023 ). However, the impact of HRT on cardiovascular health is complex and may vary depending on factors such as the timing of therapy initiation and individual risk factors ( Amirkashani et al, 2022 ).…”

Three-Dimensional Printed Attachments: Analysis of Reproduction Accuracy Compared to Traditional Attachments

“…The influence of traditional orthodontic appliances, such as brackets, on patients' aesthetic perceptions and quality of life has been widely studied. For example, Barrera-Chaparro and colleagues examined the orthodontic treatment need, types of brackets, and oral health-related quality of life, highlighting the importance of considering these factors in treatment planning [1].…”
