Introduction: To assess the effects of structured telephone follow-up on patient’s home-exercise compliance after total knee arthroplasty (TKA). Methods: A total of 202 elderly patients who received a unilateral TKA were enrolled in this study. The participants were randomized into two groups: the intervention group that received structured telephone follow-up after discharge and the control group that received routine health care. Pain, functional ability, quality of life, and depression survey scores were measured before and after TKA. The intergroup and intragroup differences were analyzed during the 12 months following discharge. Results: There were no significant differences in the sociodemographic characteristics of both groups. The mean home-exercise time and total days in the intervention group were significantly higher than those in the control group. Variable scores differed significantly between groups. Pain, functional ability, quality of life, and depression improved significantly after TKA in both groups, and the intervention group had greater improvement in mental health and active range of motion. Conclusion: Undergoing a TKA can significantly reduce the patient’s pain from osteoarthritis while improving the overall physical function and quality of life. Furthermore, a structured telephone follow-up can improve patient adherence to home exercise after TKA.

Motivation of adult female patients seeking orthodontic treatment: an application of Q-methodology Xia Tang,1 Jiaxin Cai,1 Beibei Lin,1 Linjie Yao,2 Feiou Lin3 1School of Stomatology, 2Department of Pedodontics, 3Department of Orthodontics, School of Stomatology, Wenzhou Medical University, Lu Cheng District, People’s Republic of China Background: Motivation is the impetus for patients to seek orthodontic treatment, affecting adherence, treatment outcomes, and satisfaction. The aim of this study was to assess the motivation of adult female patients seeking orthodontic treatment, and classify the patients according to their motivations.Methods: This study used Q-methodology as the main tool. Q-samples were collected and categorized (35 items). Forty-two adult female patients were interviewed before treatment as the P-sample, and their responses were categorized into the Q-methodology grid. Participants were asked to rank-order a set of 35 statements (Q-sample) from “agree most” to “disagree most” (Q-sorting). The finished Q-grids were analyzed using PQ method 2.35.Results: Four main factors were identified based on how adult female patients ranked statements: factor 1, patients who focus on their self-perception of their appearance; factor 2, patients who are concerned about the esthetics and function of their teeth; factor 3, patients who are easily influenced by others; factor 4, patients who want to improve their confidence and avoid negative thoughts caused by their teeth. The remaining patients who had other views did not match any of the above four groups.Conclusion: The motivations of adult female patients seeking orthodontic treatment are complex. This study found that most adult female patients fell into one of four typical factor groups. Our findings may improve the adherence of adult female patients by developing a more ideal treatment program. Keywords: adult female patients, orthodontic treatment, Q-methodology

The aim of this study is to assess the agreement between orthodontist’s and Chinese young adult’s self-perceived aesthetics, the normative treatment need based on the Index of Orthodontic Treatment Need (IOTN), and the main factors affecting the self-perceived aesthetics. A random sample of 348 Chinese young adults (116 males and 232 females) aged 17–24 years were recruited in this study. Two orthodontists were involved in rating the cases. Orthodontic treatment need was assessed according to the Index of Orthodontic Treatment Need, including Aesthetic components and Dental Health Components (AC and DHC). Personality traits were assessed according to Eysenck Personality Questionnaire (EPQ). Cohen’s kappa test was used to assess the agreement, and spearman’s correlation coefficient was used to analyze the association among all variables. A statistically significant level of agreement was observed between young adult’s perception and orthodontist’s perception in IOTN (kappa = 0.14). A positive relationship (p < 0.001)existed between the young adult’s AC and the orthodontist’ s AC (r = 0.275), and between the young adult’ s AC and the normative need DHC (r = 0.195). The orthodontist’s AC was strongly related to the normative need (r = 0.743, p < 0.001). Association between the young adult’s AC and gender and EPQ-E were also observed. Young adults tend to be less critical in assessing orthodontic treatment needs than orthodontists. The orthodontist’s AC reflecting subjective treatment need is strongly connected to the normative need. The adult’s perception of aesthetic component is affected by factors such as gender and personality traits.

Background: Malocclusion has significant social, psychological and physical impacts on the quality of life. This study aimed to study psychosocial impact of dental aesthetics among students, and how it was modified by personality traits. Methods: Chinese version of Eysenck Personality Questionnaire Short Scale of (EPQ-RSC) and Chinese version of Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) were used to investigate 555 undergraduate students, aged 18 to 24 years. The participants and investigators self-rated their own dental aesthetics using the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). The malocclusion was assessed by two independent investigators using the Dental Health Component (DHC) of IOTN. Results: No statistically significant difference was found for gender (p = 0.829) nor for majors (p = 0.598) in the psychosocial impact of dental aesthetics. Total and subscale PIDAQ scores differed significantly among the 3 IOTN grades. PIDAQ scores strongly correlated with Eysenck personality. The dimensions of extraversion and neuroticism, and dental health component grades had significant impact on participants' psychosocial well-being of dental aesthetics. Conclusions: Neurotic people with high self-concerns perceived greater psychosocial impact. Outgoing people appear to be less affected psychosocially by dental aesthetics.

Background. The study investigates the existing correlation between self-perceived malocclusion, the psychosocial impact of dental esthetics, and whether this link involves personality traits. Methods. The 179 questionnaires from 615 undergraduates in Wenzhou were used for analysis after applying the exclusion criteria. The Psychosocial Impact of the Dental Aesthetics Questionnaire (PIDAQ) was administered to evaluate participants perceptions of the psychosocial impacts of malocclusion. The need for orthodontic treatment was assessed using the Index of Orthodontic Treatment Need (IOTN). The Chinese version of the Eysenck Personality Questionnaire-Short Scale (EPQ-RSC) evaluated participants personality characteristics. The Kruskal-Wallis test was used to assess differences between the IOTN-Dental Health Component (DHC) and expectations of orthodontic treatment. Linear regression was applied with PADAQ and its subscale scores against possible variables. Results. The total and subscale PIDAQ scores were positively correlated with neuroticism. Total PIDAQ scores, the DHC, and the Aesthetic Component (AC) were significantly positively correlated with the subjective AC. The DHC was significantly negatively correlated with extroversion. Conclusions. We confirmed a modest link between the need for orthodontic treatment and the psychosocial impact of dental esthetics.
