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.

Self-perception and self-recognition of facial profiles in adolescents referred to orthodontic treatment

OBJECTIVES

To investigate self-recognition and self-perception among participants with straight, convex, and concave profiles.

MATERIALS AND METHODS

This cross-sectional study was conducted using a questionnaire with questions about demographic information, self-perception of the facial profile, satisfaction with profile esthetics, expectations about profile changes after completing orthodontic treatment, motivational factors, and self-recognition. For the self-recognition question, profiles of the respondents were blackened and inserted into the questionnaire. Participants were categorized into three groups: those exhibiting a convex, straight, and concave profile.

RESULTS

There was no statistically significant difference between the straight, concave, and convex profile groups regarding self-recognition and self-perception. Participants showed greater ability in self-recognition than self-perception of their soft-tissue profile (P = .001). Females showed higher capability in self-perception than males (P = .001).

CONCLUSIONS

Self-recognition and self-perception of the soft-tissue profile are not influenced by facial convexity.

Assessment of psychosocial parameters in adolescents seeking orthodontic treatment

AIM

The aim of this study was to investigate the psychosocial impact of malocclusion and the motivation for seeking orthodontic treatment among adolescents.

METHODS

A cross-sectional study included 102 adolescents (ages 11-18) whose malocclusion was rated using 3 occlusal indices: IOTN, DAI, and PAR. The participants answered three structured questionnaires selected to measure Oral Health Related Quality of Life (OHRQoL) through the short form of the Child Oral Health Impact Profile (COHIP), the patient's perceived impact related to orthodontics through the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), and self-esteem through the Rosenberg Self-Esteem Scale (RSES). Independent two-tailed t-tests, one-way mixed analysis of variance (ANOVA), and Spearman's correlations were used to test various associations.

RESULTS

Patients with higher malocclusion scores displayed increased psychosocial impact with weak to moderate correlations (0.2 < r < 0.3; p < 0.05), but 98% wished their teeth looked better, and 70% were unhappy about their smile esthetics. The IOTN esthetic component AC was better associated with psychosocial implications of malocclusion (p < 0.01). Self-motivated patients (over 80%) had higher impactful psychosocial scores than patients whose parents were motivated for treatment. Sex did not influence the findings. Older adolescents and bullied individuals were more affected by the psychological burden of malocclusion.

CONCLUSION

The results indicate the prevalence of psychosocial and esthetic impacts of malocclusion over oral and functional problems. PIDAQ discriminated better than COHIP between varying degrees of dental aesthetics. The results suggest that the orthodontist should explore patients' expectations of treatment outcomes, not only the chief complaint.

Correlations among satisfaction parameters after orthodontic treatment

OBJECTIVE

This study assessed patient's satisfaction after orthodontic treatment in the postgraduate orthodontic clinic of the Dental School at the University of Athens (Athens, Greece), and investigated possible correlations between satisfaction after orthodontic treatment and life satisfaction, alongside the influence of age, gender, severity of initial orthodontic malocclusion and duration of retention period.

MATERIAL AND METHODS

Patients aged 12 years and above, who had recently completed comprehensive orthodontic treatment, participated completing two questionnaires: a 37-item questionnaire, validated for assessing orthodontic treatment satisfaction; and the 5-item Satisfaction with Life Scale, a valid and reliable measure of life satisfaction. Scores from each questionnaire were summed for each patient. Demographic details, Index of Orthodontic Treatment Need (IOTN) and the duration of the retention period up to questionnaire completion were collected. Multiple regression analysis assessed the relationship between the questionnaires and the evaluated variables.

RESULTS

A total of 150 patients answered the questionnaires, being 82 women (55%) and 68 men (45%). The mean age of patients was 18.87 ± 5.97 years (range: 12-47). Most patients expressed satisfaction with treatment outcomes (grades 5 and 6). Satisfaction with orthodontic treatment showed a significant correlation with life satisfaction (p=0.002), but not with gender, age, dental/esthetic components of IOTN, or the duration of the retention period.

CONCLUSION

Satisfaction after orthodontic treatment exhibited a significant correlation with life satisfaction, but it was not affected by gender, age, dental/esthetic components of IOTN, or the duration of the retention period.

Patients' perceptions matter: Risk communication and psychosocial factors in orthodontics

INTRODUCTION

Effective risk communication is essential for achieving patient-centered oral health care, but the limited understanding of patients' subjective perceptions of orthodontic-related risks hinders this process. This study aimed to investigate adults' awareness, concerns, and risk-avoidance behaviors about long-term orthodontic risks, exploring their relationship with psychosocial factors.

METHODS

We included 498 adult patients (mean age, 27.3 ± 6.8 years; women, 75.5%) during their initial visits to the orthodontic department at a hospital in Chengdu, China. Participants' understanding of orthodontic risks was gauged before and after exposure to the Oral Health Education Comics (OHEC), a specifically designed digital tool. Concurrently, we used logistic regression models to investigate the associations between patients' depression, anxiety, self-esteem, perfectionism, and dentofacial esthetics with risk perceptions.

RESULTS

Approximately 79.5% of participants initially reported low awareness of orthodontic risks, with most knowledge from online sources. Notably, the percentage of participants with high awareness increased to 64.8% after OHEC. The negative facial soft-tissue change was most concerning for participants: 53.4% showed high concerns, and 28.1% showed high avoidance. Furthermore, linear regression indicated positive associations between depression (β = 0.42 [95% confidence interval {CI}, 0.07-0.77]) and anxiety (β = 0.76 [95% CI, 0.35-1.18]) with orthodontic risk concerns, whereas risk avoidance was positively associated with depression (β = 0.62 [95% CI, 0.27-0.97]), anxiety (β = 1.09 [95% CI, 0.68-1.50]), and perfectionism (β = 0.24 [95% CI, 0.02-0.46]).

CONCLUSIONS

Findings emphasize the imperative of streamlined risk communication in orthodontics. By incorporating comprehensible tools such as OHEC and integrating psychosocial evaluations, more refined patient-practitioner communication and psychosomatic-based dental care can be achieved.

Comparison of the Opinions of Adolescents With Different Orthodontic Treatment Needs

BACKGROUND

The aim of this study was to compare oral health-related quality of life (OHRQoL) among adolescents granted (G) versus not granted (NG) publicly funded orthodontic treatment.

MATERIALS AND METHODS

Adolescents aged 15-20 years who were granted versus not granted publicly funded orthodontic treatment responded to a web-based survey, assessing OHRQoL in relation to functional impact, psychological impact, and motivators for orthodontic treatment. Before the survey, pretesting of the questionnaire was conducted to ensure its reliability. Differences between the groups were tested using the chi-squared and Mann-Whitney U-tests. Reliability was assessed using Cohen's κ and Pearson's correlation coefficient during the pretest phase.

RESULTS

One hundred and forty patients, equally distributed between a G and an NG group, responded to the survey. Gender, age, and demographic distribution were comparable in both groups. All respondents expressed a high subjective treatment need and similar answers regarding functional aspects. Orthodontic treatment motivators (G: 86.2% and NG: 94.7%, p = 0.443) were primarily related to improved self-esteem, overall well-being, facial appearance, and being able to laugh without embarrassment. The NG group expressed a more negative OHRQoL impact due to the appearance of their teeth compared with the G group (p < 0.001) and a negative impact caused by the position of their teeth (p < 0.001).

CONCLUSIONS

Orthodontic treatment need indices should aim to reinforce subjective measures as adolescents express similar motivators for orthodontic treatment, regardless of the clinician's objectively based decision about treatment need.

Adult orthodontics, motivations for treatment, choice, and impact of appliances: A qualitative study

INTRODUCTION

Understanding the rationale for adult patients undertaking orthodontic treatment and the impact of appliances on their quality of life has become increasingly important to research efforts and clinical care. This study aimed to understand why adult patients undergo orthodontic treatment and their overall experience with the choice of appliance.

METHODS

A cross-sectional qualitative study using semistructured interviews with adult patients from 4 private specialist orthodontic practices in the London region involving a purposive homogeneous sampling technique to obtain variation regarding gender, treatment modalities (fixed ceramic [FC], removable aligner [RA], and fixed lingual [FL] appliances), and stages of treatment (early, late, and posttreatment stage) was undertaken. A piloted topic guide was used to standardize data collection. Interviews were audio recorded, and field notes were taken. Data were transcribed verbatim and analyzed using framework methodology until data saturation was reached.

RESULTS

A total of 22 participants (FC, 8; RA, 8; and FL, 6), with a mean age of 38.9 ± 11.7 years, with the majority being female (n = 13; 59.1%), were interviewed. Psychosocial and dental health-related factors were reported as the main reasons to seek orthodontic treatment. Social factors and appliance features influence an adult's decision-making in selecting a specific orthodontic appliance. Wearing FC, RA, and FL was seen to have both positive and negative impacts on an adult's quality of life. Functional and psychological factors were the strong influencers on patients' treatment experience.

CONCLUSIONS

The study highlighted the influence of psychosocial factors and dental health concerns in the decision-making processes of adults seeking orthodontic treatment. FC, RA, and FL appear to affect an adult's quality of life, with functional and psychosocial factors being commonly reported.

Smile attractiveness in patients treated with or without 4 premolar extractions: A 36-year follow-up

INTRODUCTION

This study aimed to assess the smile attractiveness in patients treated with or without 4 premolar extractions at a 36-year follow-up.

METHODS

The sample comprised 52 patients with Class I and II malocclusion divided into 2 groups. Group 1 consisted of 15 patients treated without extractions (10 females and 5 males), with a mean pretreatment, posttreatment, and long-term posttreatment (T3) age of 13.2, 15.1, and 49.8 years, respectively. The mean treatment time was 1.9 years, and the mean long-term follow-up period was 34.7 years. Group 2 consisted of 37 patients (25 females and 12 males) treated with 4 premolar extractions, with a mean pretreatment, posttreatment, and long-term posttreatment age of 13.3, 15.7, and 53.6 years, respectively. The mean treatment time was 2.3 years, and the mean long-term follow-up period was 37.9 years. The mean retention time was 2 years for both groups. Frontal smiling photographs were obtained at long-term follow-up. Smile attractiveness was evaluated in an online questionnaire in which the evaluator could rate the smiling photographs with a 10-point scale. The randomly selected evaluator sample consisted of 62 laypeople, 33 dentists, and 89 orthodontists. Independent t tests, 1-way analysis of variance, and Tukey tests were used for intergroup comparisons at P <0.05.

RESULTS

The smile attractiveness on the long term was similar in the groups treated with 4 premolar extractions (4.70 ± 1.35) or without extractions (4.51 ± 1.46). Women and orthodontists were more critical in assessing smile attractiveness than men, dentists, and laypeople.

CONCLUSIONS

After long-term posttreatment, the smile attractiveness was similar in patients treated with 4 premolar extractions or without extractions.

Long-term profile attractiveness of patients with Class I and II malocclusion treated with and without extractions: A 35-year follow-up

INTRODUCTION

The objective of this study was to compare the profile attractiveness in subjects treated with and without extractions after the long-term 35-year follow-up, according to laypeople, dentists, and orthodontists.

METHODS

A total of 40 patients with Class I and II malocclusion were divided into 2 groups, according to the treatment protocol: extraction (E) group, extractions of 4 premolars (n = 24), with mean pretreatment (T1), posttreatment (T2), and long-term posttreatment (T3) ages of 13.13, 15.50 and 49.56 years, respectively. The mean treatment time (T2 - T1) was 2.37 years, and the long-term follow-up (T3 - T2) was 34.19. Nonextraction (NE) group (n = 16), with mean ages at T1, T2, and T3 of 13.21, 15.07, and 50.32 years, respectively. The mean (T2 - T1) was 1.86 years, and the (T3 - T2) was 35.25 years. Lateral cephalograms were used to perform profile facial silhouettes, and an online evaluation was performed by 72 laypeople, 63 dentists, and 65 orthodontists, rating the attractiveness from 1 (least attractive) to 10 (most attractive). The intragroup comparison was performed with the repeated measures analysis of variance and Tukey tests. Intergroup comparison was performed with t tests, 1-way analysis of variance, and Tukey tests.

RESULTS

The E group had a longer treatment time than that of the NE group. In the pretreatment, posttreatment, and long-term posttreatment stages, the E and NE groups showed similar profile attractiveness. Laypersons and dentists were more critical than orthodontists.

CONCLUSIONS

At long-term posttreatment follow-up, profile attractiveness was similar in patients treated with and without extractions.

Oral Health-Related Quality of Life among Adolescents in the First 6 Months of Fixed Orthodontic Therapy

Clarification on disabilities that may arise during orthodontic treatment allows patients to have more realistic expectations. This prospective study assessed the impact of fixed orthodontic therapy on adolescents' quality of life over 6 months. A total of 78 adolescents aged 11-17 years were included. Quality of life was measured using the Child Perceptions Questionnaire (CPQ11-14, short form) at five moments: before treatment (T0), one week (T1), one month (T2), three months (T3), and six months (T4) after treatment initiation. Multiple and pairwise comparisons were conducted for CPQ11-14 scores (Friedman and Wilcoxon test; effect size). Changes in the quality of life were assessed as mean differences (T0-T1 and T0-T4) in total and domain scores (Kruskal-Wallis and Mann-Whitney test) (α = 5%). Significant differences were observed between T0 and T4 in the oral symptoms' domain (p < 0.001), and between T0 and T1, T2, T3, and T4 for emotional well-being (p < 0.001 for all). Significant differences in impact were also found between T0 and T2, T3, and T4 with regard to social well-being (p = 0.004, =0.049, and <0.001, respectively). Orthodontic therapy positively impacted the emotional and social aspects of adolescents' quality of life. Negative effects were primarily related to pain, mouth sores, and difficulty biting or chewing. Understanding the symptoms and feelings of orthodontic patients aids professionals in decision-making.

Impacts of using orthodontic appliances on the quality of life of children and adolescents: systematic review and meta-analysis

BACKGROUND

Although there are previous systematic reviews about the oral health-related quality of life (OHRQoL) impact among children and adolescents after orthodontics treatment, there is no definition for the magnitude of these impacts during the therapy.

OBJECTIVE

To systematically analyse the literature on changes in the quality of life of children and adolescents during orthodontic treatment.

LIMITATIONS

Almost all the studies included in this review are non-randomized clinical trials, which are susceptible to several biases that affect the certainty of evidence obtained, especially by confounding factors and the lack of a control group.

CONCLUSIONS AND IMPLICATIONS

Based on very low certainty of evidence, wearing appliances does not seem to have a significant negative impact during the first year of orthodontic treatment. However, the meta-analytic results suggest that functional limitations in the first 3 months of treatment can be slightly more critical for the impact on the oral health quality of life and consequent patient adherence to treatment.

FUNDING

This study was financed by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brazil (CAPES), Conselho Nacional de Desenvolvimento Científico e Tecnológico - Brazil (CNPq), and Fundação de Amparo à Pesquisa do Estado de Minas Gerais - Brazil (FAPEMIG).

Difference and relation between adolescents' and their parents or caregivers' reported oral health-related quality of life related to orthodontic treatment: a prospective cohort study

BACKGROUND

Parents/caregivers play an important role in deciding whether their children will undergo orthodontic treatment or not. Their perceptions also have an influence on other choices involving orthodontic treatment. The purpose of this study was to investigate the difference and correlation between the ratings given by children and their parents or caregivers on their oral health-related quality of life (OHRQoL) before, during and after orthodontic treatment.

METHODS

In this ongoing observational prospective cohort study, 498 children aged 11 to 16 years-old and one of their parents/caregivers completed questionnaires before (T0), 1 year after start (T1) and 1 month after the end of orthodontic treatment (T2). OHRQoL was scored by using the Child Perception Questionnaire (CPQ11-14) and the Parental-Caregiver Perception questionnaire (P-CPQ). The self-perception of oral aesthetics was evaluated with the Oral Aesthetic Subjective Impact Scale (OASIS) in addition to the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN). Spearman correlations, Mann-Whitney U-tests and linear models were used to analyze the longitudinal data.

RESULTS

At T0, the ratings of parents/caregivers were significantly lower for the total CPQ as well as for the subdomains of oral symptoms, functional limitations and emotional well-being. Parents/caregivers also scored significantly lower at T2 for the total CPQ and the subdomain of oral symptoms. The relations between the scores of children and their parents/caregivers were significant at all three time points, as were the changes in scores, but all of them were at most moderate in size. Parents/caregivers scored significantly lower for OASIS than their children at all time points and only at baseline a significant, weak correlation was found.

CONCLUSION

The reports of parents/caregivers should be seen as important complementary information in OHRQoL research.

TRIAL REGISTRATION

A New Approach to Maxillary Protrusion with an Unstable Mandibular Position Accompanied with Unidentified Complaints: Case Report

This case report describes the importance of combining morphological and functional examination with psychological examination in the establishment ofstable mandibular position in the treatment of maxillary protrusion with unstable mandibular position accompanied by unidentified complaints, which ensures safe orthodontic treatment.

Assessment of the Attitude and Knowledge of the Principles and Practices of Orthodontic Treatment Among the Non-orthodontic Specialists and General Practitioner Dentists

Introduction

General practitioner dentists and non-orthodontic specialties ought to have the knowledge of the basic principles and practices of orthodontics in order to educate the patients, diagnose their problems correctly and for proper referral. The objective of the present study is to assess the attitude and knowledge of the general practitioner dentists and non-orthodontic specialists towards the basic principles and practices of orthodontics.

Methods

This study was performed by presenting a closed questionnaire to a total of 78 participants out of which 46 were general practitioners and 32 were non-orthodontic specialists. A questionnaire consisting of a total of 21 questions was distributed and each question was allocated 0.5 marks for correct response whereas no deduction for wrong answer.

Results

In this present study, the total mean score of the evaluation of the questionnaire came out for general practitioner dentist and the non-orthodontic dental specialists was 13.92 and 16.69 respectively. The present study showed a statistically highly significant knowledge and attitude difference between Group A and Group B ( P<0.001).

Conclusions

This study shows a need for a increased clinically oriented education in the undergraduate courses and a multi-disciplinary inter department seminar presentations and forums set up for the post graduation courses for them to understand the scope of each other's specialties.

Experiences Of Individuals Concerning Combined Orthodontic and Orthognathic Surgical Treatment: A Qualitative Twitter Analysis

OBJECTIVE

The aim of this qualitative study was to analyze the content of posts on Twitter in order to gain an in-depth understanding of patients' thoughts and experiences surrounding orthognathic surgical treatment.

MATERIALS AND METHODS

Using the Twitter search function, with the keywords "jaw surgery," the 1,000 most recent posts on Twitter with relevance to a combined orthodontic and orthognathic surgical treatment were extracted. After applying relevant inclusion and exclusion criteria, the selected posts were analyzed using thematic analysis by 2 independent investigators. Distinct themes and subthemes were developed.

RESULTS

A total of 689 posts were analyzed; the 3 main themes identified in relation to orthognathic surgery were preoperative engagement, postoperative difficulties, and posttreatment satisfaction. Twelve subthemes were also identified, expressing issues such as anticipation or apprehension of the surgical procedure, postoperative pain and edema, dietary restrictions and weight loss, paresthesia, depression, and satisfaction with improvements in appearance and self-confidence. The 6 terms most frequently used in tweets were "recovery," "braces," "swollen," "eat," "liquid diet," and "pain."

CONCLUSIONS

The findings from the present study can increase the awareness of clinicians involved in the combined orthodontic and orthognathic surgical treatment of patients with dentofacial deformities, allowing them to better educate and counsel their patients throughout the entire treatment process.

Esthetic perception of changes in facial profile resulting from orthodontic treatment with extraction of premolars: A systematic review

BACKGROUND

The authors conducted a systematic review to assess changes in patients' facial profiles resulting from orthodontic treatment with and without extraction of 4 premolars and to identify cephalometric parameters that can assist decision making in borderline cases.

TYPES OF STUDIES REVIEWED

The authors conducted a systematic review of randomized clinical trials and observational studies comparing the 2 types of treatment (with and without premolar extraction) in terms of the changes in facial profile. The authors conducted an electronic search of the databases the Cochrane Library, PubMed MEDLINE, Embase, and Latin-American and Caribbean Health Sciences Literature.

RESULTS

The authors identified 1 clinical trial with 26 participants and 5 observational cohort studies, collectively involving 362 participants. The authors assessed cephalometric parameters and esthetic outcomes. Four studies used linear regression analysis to investigate esthetic interaction between treatment strategy and initial lower lip protrusion. The 4 studies determined that if the initial lip protrusion was beyond a determined point, esthetic preferences favored extraction, and if the initial lip protrusion was not to that point, esthetic preferences favored conservative treatment.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

The results of the authors' systematic review found no significant differences between the groups in terms of the esthetic outcomes. The cephalometric parameter of initial lip protrusion can help with decision making in borderline cases.

Dental aesthetics perception and eating behavior in adolescence

BACKGROUND

This correlational study explored the psychosocial aspects related to eating behavior in different age samples of adolescents in treatment from 0 to 60 months at the Clinic of Orthodontics and Dentistry of Messina, Messina, Italy. The aim of the study was to investigate the relationship between psychosocial impact, levels of self-esteem, and the possible connection with eating habits of adolescents under orthodontic treatment.

METHODS

Sixty-one adolescents, aged between 12 and 22 years (mean=15.6 ± 2.8) participated to the study. Each adolescents was interviewed with the Eating Attitudes Test, the Rosenberg Self Esteem Scale, and the Psychosocial Impact of Dental Aesthetics Questionnaire.

RESULTS

Data did not show a direct connection between eating disorder and dental aesthetics, nevertheless, adolescents under orthodontic treatment, especially in the earliest phase of wearing braces, showed peculiar eating habits and underwent a higher psychological impact of dental aesthetics. Eating behaviors are strictly linked to global self-esteem. The processing of the results was made through the Student's t-test and using Pearson's correlation analysis.

CONCLUSION

Increased knowledge of the psychological aspects involved in orthodontic treatment compliance may have positive effects in the relationship between adolescent patients and orthodontists. More attention should be paid to aspects that are often underestimated in clinical practice, thus, influencing the outcome of treatment and patient satisfaction, not only in terms of dental health, but also of mental health.

[How to evaluate psychological risks: an ethics of aesthetic demand in orthodontics]

Evaluating risks is part of the day-to-day practice of all orthodontists. Most of the time we forget that healing a patient also requires an evaluation of what is called the psychological risk. Indeed, focusing on harmonisation matters, we tend to omit that patient's requests, especially aesthetic requests, may conceal psychological problems. Such a risk is even higher when it comes to orthodontic-surgical protocols, as the physical changes are more radical. We will discuss the specificities of aesthetical demand, its links with the social discourse and the way self-esteem and reflection in the mirror are closely intermingled. Should we forget to take into account the psychological dimension of any patient, this could be a breach of professional ethics. We will furthermore consider the means we have to recognize patients with a high psychological risk. It is not in our hands to help these patients psychologically. It is in the hands of a mental health specialist, whose adress and phone number we should know in order to refer our patients to him/her.

Evaluation of health related quality of life changes after initial orthodontic treatment

PURPOSE

To evaluate the changes of Oral Health Related Quality of Life (OHRQoL) in patients after the placement of a fixed orthodontic appliance.

MATERIALS AND METHODS

This prospective study consisted of 148 adolescents (97 girls and 51 boys) between the ages of 14 and 17 who were patients of an orthodontic clinic. OHRQoL was assessed by a modified questionnaire that evaluated four domains: oral symptoms, functional limitations as well as emotional and social well-being in three time frames: before bonding and banding (T(0)), two months after initiating orthodontic treatment (T(1)) and six months after initiating orthodontic treatment (T(2)). The repeated measures test was used to compare the relative changes of OHRQoL among the different time frames.

RESULTS

There were no significant differences between the levels of OHRQoL and its domains for boys or girls at any time point. The overall level of OHRQoL decreased significantly at T(1) relative to T(0); however, the emotional well-being domain improved at T(1) in comparison to T(0). At T(2), the OHRQoL level increased significantly relative to T(0) in all domains.

CONCLUSION

The patients' quality-of-life level decreased by initiating orthodontic treatment; however, during that period, emotional well-being increased. As orthodontic treatment progressed, the quality of life level increased.

Comparison of personality traits, attitude toward orthodontic treatment, and pain perception and experience before and after orthodontic treatment

OBJECTIVE

To compare personality traits, attitude toward orthodontic treatment, and pain perception and experience before and after orthodontic treatment.

MATERIALS AND METHODS

One hundred subjects (50 male and 50 female) were included in this study. The mean (SD) age was 17.5 (2.05) years at T1 and 19.15 (2.32) years at T2. The instruments for data collection were questionnaires that included assessment of patients' personality traits, attitudes toward orthodontic treatment, and pain perception/experience. Subjects completed the questionnaires at two different times: before orthodontic treatment (T1) and after fixed orthodontic treatment (T2). Subjects were treated by fixed orthodontic appliances for an average (SD) period of 18.64 (0.35) months. Paired sample t-test and chi-square test were used to detect any differences.

RESULTS

Significant changes in personality traits were detected after orthodontic treatment irrespective of gender. Neuroticism, openness, agreeableness, and conscientiousness scores were improved (P < .001). A positive attitude toward orthodontic treatment was reported at T1 (4.31 [±1.26]) and improved at T2 (3.98 [±1.16]) irrespective of gender (P < .05). The average (SD) expected pain score (T1) was 4.73 (1.88) and the average (SD) experienced pain score (T2) was 4.63 (1.58). Significant difference in the expected and experienced pain scores was not detected (P  =  .11).

CONCLUSIONS

Personality traits and attitude toward orthodontic treatment improved after orthodontic treatment. Reported actual pain experience during orthodontic treatment was similar to that expected before treatment.

Desire for orthodontic treatment and associated factors among adolescents in Southern Brazil

OBJECTIVE

To estimate the prevalence of the desire for orthodontic treatment and investigate associated factors among adolescents in southern Brazil.

MATERIALS AND METHODS

A cross-sectional study was carried out with 704 adolescents aged 12 and 13 years at municipal public schools in the city of Balneário Camboriú (southern Brazil). The adolescents answered a previously tested questionnaire addressing satisfaction with their dental appearance, speech function, chewing function, and the desire for orthodontic treatment. The parents/guardians answered a questionnaire addressing satisfaction with their child's dental appearance and socioeconomic variables. A trained and calibrated orthodontist collected clinical data on malocclusion using the Dental Aesthetic Index (DAI). Statistical analysis was performed using multivariate Poisson regression with robust variance.

RESULTS

The prevalence of the desire for orthodontic treatment was 69.6% (490/704). In the adjusted analysis, the outcome was significantly more prevalent among girls (P < .001), those with difficulty chewing (P  =  .026), those dissatisfied with their dental appearance (P < .001), and those with greater malocclusion severity (P < .001). The following orthodontic characteristics were associated with the desire for orthodontic treatment in the multivariate model: diastema in anterior segment (P < .001), anterior maxillary irregularity (P < .001), maxillary overjet ≥6 mm (P < .001), and mandibular overjet (P  =  .047).

CONCLUSIONS

The desire for orthodontic treatment among 12- and 13-year-old adolescents is influenced by gender, dissatisfaction with one's dental appearance, difficulty chewing, malocclusion severity, and orthodontic characteristics. These findings should be considered together with normative indications regarding the need for orthodontic treatment in adolescents.

How patient and carer expectations of orthodontic treatment vary with ethnicity

OBJECTIVE

To investigate if the orthodontic treatment expectations of Black British children and their primary carers vary compared with White British children and their primary carers.

SETTING

A hospital orthodontic department (Queen Mary's Hospital, Sidcup, London, UK).

PARTICIPANTS

Patients and their accompanying primary carers who had not received fixed orthodontic appliance treatment and were aged between 12 and 14 years old.

METHOD

Informed consent was obtained from 100 patients and their primary carers, who completed a psychometrically validated questionnaire, to measure their expectations before a new patient orthodontic consultation. This cohort consisted of 50 Black British patients and their primary carers and 50 White British patients and their primary carers.

RESULTS

Mean responses from patients and their primary carers for each ethnic group were compared using the independent groups t-test. Significant statistical differences were found between the two ethnic groups. The greatest statistical differences occurred between Black British patients and their primary carer and Black British primary carers and White British primary carers. Patients tended to have similar orthodontic expectations. There were no statistical significant differences in expectations between White British children and their primary carers.

CONCLUSION

Differences in expectations of orthodontic treatment were more common between Black British and White British primary carers, than their children. White British primary carers had higher expectations at their child's initial appointment and expected dental extractions to be part of the orthodontic treatment plan. These differences have some implications for the provision of orthodontic care. A clinicians understanding of patients and their primary carer's expectations at the start of treatment can help in the quality and delivery of orthodontic care provided.

Perception of the relationship between TMD and orthodontic treatment among orthodontists

INTRODUCTION

The consensus about the relationship between TMD and orthodontic treatment has gone from a cause and effect association between TMD and orthodontic treatment to the idea that there is no reliable evidence supporting this statement.

OBJECTIVE

To assess the beliefs, despite scientific evidence, of Brazilian orthodontists about the relationship between TMD and orthodontic treatment with regards to treatment, prevention and etiology of TMD.

METHODS

A survey about the relationship between TMD and orthodontic treatment was prepared and sent to Brazilian orthodontists by e-mail and social networks. Answers were treated by means of descriptive statistics and strong associations between variables were assessed by qui-square test.

RESULTS

The majority of orthodontists believe that orthodontic treatment not only is not the best treatment option for TMD, but also is not able to prevent TMD. Nevertheless, the majority of orthodontists believe that orthodontic treatment can cause TMD symptoms.

CONCLUSION

This study suggests that orthodontists' beliefs about the relationship between orthodontic treatment and TMD are in accordance with scientific evidence only when referring to treatment and prevention of TMD. The majority of orthodontists believe that, despite scientific evidence, orthodontic treatment can cause TMD.
