Age-Related Quality of Life and Psychosocial Impact of Chin Asymmetry in Adolescents and Young Adults Undergoing Orthodontic and Orthognathic Correction

Knowledge, attitude, and practice of adolescents and parents toward malocclusion and orthodontic treatment

Malocclusion is the misalignment of teeth and jaws, affecting oral health and appearance. This study aimed to examine the knowledge, attitude, and practice (KAP) of both adolescents and parents toward malocclusion. This web-based cross-sectional study was conducted at Tianjin between July 2019 and July 2022, enrolled adolescents and their parents. The structural equation model (SEM) was used to analyze the interactions between KAP. A total of 478 adolescents and 380 parents were included. For knowledge, the scores were 6.95 ± 2.69 for adolescents and 7.07 ± 2.90 for parents (possible range, 0-12). For attitude, the scores were 36.96 ± 7.86 for adolescents and 33.26 ± 9.20 for parents (possible range, 13-65). For practice, the scores were 39.88 ± 7.85 for adolescents and 25.75 ± 8.56 for parents (possible range, 11-55). In parents, knowledge, practice, being a service personnel and production personnel, and acquiring knowledge through the Internet were associated with receiving orthodontic treatment. The SEM showed that knowledge directly affected attitudes (β = 0.551, P < 0.001) and practices (β = 1.122, P < 0.001). But attitudes did not affect practices (β=-0.003, P = 0.923). Adolescents and parents demonstrate unsatisfactory levels of knowledge, attitudes, and practices toward malocclusion. Improvements can be made by focusing on enhancing knowledge and encouraging proactive practices.

The change of state-trait anxiety among patients undergoing orthognathic surgery: A longitudinal study

INTRODUCTION

This study aimed to assess state-trait anxiety level changes in Chinese patients with dentofacial discrepancies before and after orthognathic surgery and to explore the feasibility of developing a reference index for the preoperative screening of postoperative patients with high anxiety.

METHODS

A total of 96 Chinese patients with dentofacial discrepancies who underwent orthognathic surgery were included in this study. Data were collected before orthognathic surgery and at 2 weeks (T2), 3 months, and 6 months (T4) after surgery using the State-Trait Anxiety Inventory. Receiver operating characteristic and linear regression analyses were performed to screen for preoperative indicators of postoperative high-state anxiety.

RESULTS

State-trait anxiety levels in patients with dentofacial discrepancies decreased after surgery (F = 18.95, P <0.01; F = 6.90, P <0.01). Trait Anxiety Inventory can be used to screen patients with high-state anxiety from T2 to T4 (area under cover 95% confidence interval: T2, 0.74 [0.62-0.86]; 3 months, 0.79 [0.69-0.90]; T4, 0.77 [0.66-0.87], P <0.01), corresponding to cutoff values of 48.5, 46.5, and 45.5, respectively.

CONCLUSIONS

All participants' state-trait anxiety levels improved after surgery compared with their preoperative levels. Preoperative trait anxiety levels can be used as a reference indicator to screen patients who may have high-state anxiety levels after orthognathic surgery. The creation of a screening scale will assist health care professionals to more pertinently help patients with high anxiety.
