Psychological impact of orthodontic treatment on quality of life - A longitudinal study

Enhancing Orthodontic Renewal and Retention Techniques: A Systematic Review

Orthodontists have a variety of options available for retainers. Research in Orthodontics focuses on assessing outcomes important to clinicians; however, there is inconsistency in how these outcomes are selected and evaluated. This review sought to assess the effects of different orthodontic retainers on patients' quality of life (QoL). Various approaches were employed in this systematic review, and a thorough search was conducted across six databases. The review involved a comprehensive evaluation of six included studies, highlighting changes in dental structure post-treatment, emphasizing the role of extraction procedures and the quality of debonding in improving retention. The study identified key outcomes for orthodontic clinical trials, highlighting orthodontists' preferences for specific retainer types. Moreover, it discussed the impact of sociocultural influences on retention care. Involving patients actively in discussions about whether to end or extend the retention phase was deemed essential. Noteworthy improvements in occlusal outcomes were linked to extraction treatments. Gender and malocclusion severity influenced QoL before and after orthodontic treatment. The degree of improvement observed in the Class III malocclusion group was comparatively lower than that in the Class I and Class II groups. Orthodontic treatment was found to yield favorable psychological outcomes, as evidenced by notable enhancements in self-esteem and social engagement among individuals. Fixed appliances were shown to negatively affect oral health-related quality of life (OHRQoL), particularly for those with aesthetic and functional concerns. A consensus has been reached on the essential themes and outcomes that should be incorporated in clinical trials related to orthodontic retention for non-cleft and non-surgical cases.

Profile of Orthodontic Use across Demographics

OBJECTIVES

Population-based studies have focused on patients' rendering of orthodontic treatment due to their malocclusion and medical needs. However, there is a scarcity of data from national sources on the prevalence of orthodontic visits and associated patient characteristics, as well as their effect on dental health. This study evaluated the demographic differences of orthodontic patients and examined the association between orthodontics use and risk of periodontal disease and oral surgical intervention.

METHODS

This study used data collected from the 2019 Medical Expenditure Panel Survey. Descriptive statistics were used to evaluate socio-demographics and covariates by the use of orthodontics. Chi-square tests were used to assess demographic differences among respondents who stated whether or not they used orthodontics. Logistic regression models were then used to examine the association of orthodontics and oral health outcomes.

RESULTS

The sample size was 12,422, of which 491 respondents indicated a usage of orthodontics. There were significant differences among demographic variables (p < 0.05) that included 61.1% females, 60.8% Whites, 67.6% participants under the age of 18 years old, and a family total income of $100,000 or more (52.7%). After controlling for socio-demographics and covariates, individuals who used orthodontics were less likely to have periodontal disease (AOR = 0.623, 95% CI = 0.610 to 0.637) and tooth extractions (AOR = 0.071, 95% CI = 0.070 to 0.073) than those who did not.

CONCLUSIONS

Our findings indicate orthodontics usage was higher in females, younger patients, and Whites, highlighting the possible demographic disparities in orthodontics use. Additionally, those who used orthodontics were less likely to have oral health issues.

Knowledge, attitudes, and interest in orthodontic treatment: a cross-sectional study in adults with stage III-IV periodontitis and secondary malocclusions

BACKGROUND

An increasing number of patients with advanced stages of periodontitis are seeking for treatment options. The study aimed to determine interest in orthodontic treatment (OT) and its association with oral health status and knowledge about the disease in adult subjects with stage III-IV periodontitis.

METHODS

96 subjects ≥ 30 years, with stage III-IV periodontitis agreed to fill in a questionnaire and undergo a comprehensive periodontal-orthodontic examination. The questionnaire included 44 questions: demographic, dental, health related habits, self-perceived overall and oral health, knowledge of periodontitis, and attitude toward OT. The statistical analysis was performed using a paired-sample T-test, Receiver Operating Characteristic (ROC) and binary logistic regression analysis (LRA).

RESULTS

Stage IV periodontitis was observed in 32.3% of subjects and Class II malocclusion was most prevalent (53.1%). More than half of subjects were interested in OT. Oral health, knowledge about periodontitis and age were significant predictors for interest in OT.

CONCLUSIONS

Knowledge spread about OT possibilities in advanced stages of periodontitis is very important both for the dental community and older subjects to save natural dentition.

Effect of Plant-Based Mouthwash (Morinda citrifolia and Ocimum sanctum) on TNF-α, IL-α, IL-β, IL-2, and IL-6 in Gingival Crevicular Fluid and Plaque Scores of Patients Undergoing Fixed Orthodontic Treatment

Background and Objectives: To investigate the antiplaque properties of two plant-based mouthwashes, Morinda citrifolia (MC) and Ocimum sanctum (OS), and their effect on TNF-α, IL-α, IL-β, IL-2, and IL-6 in gingival crevicular fluid (GCF) of patients undergoing fixed orthodontic treatment. Materials and Methods: Seventy-five individuals were recruited according to defined inclusion and exclusion criteria. This study was structured into two distinct phases. Phase I was a combination of toothbrushing using toothpaste containing fluoride (Protocol A), while Phase II toothbrushing included fluoride toothpaste and use of a mouthwash (Protocol B). For Phase II, individuals participating in this study were allocated into different groups through a randomization process: Group 1-0.12% CHX, Group 2-5% MC, and Group 3-4% OS. Each individual's Phase I and Phase II scores were assessed. GCF was measured in three phases to determine the level of inflammatory biomarkers. The paired t-test evaluated the disparities between the pre- and post-plaque index. Categorical data were subjected to crosstab analysis to assess qualitative variables. The mean values of cytokine levels were presented. An unpaired t-test was employed to assess the levels of cytokines between individuals in Phase I and Phase II. Results: Toothbrushing, fluoride toothpaste, and the supplementary use of mouthwash (Phase II) resulted in mean plaque scores significantly lower than group A (p < 0.001). Cytokines TNF-α, IL-α, and IL-β demonstrated a significant downward trend in herbal mouthwash users. Conclusions: In conjunction with fluoridated toothpaste and brushing, OS and MC can serve as a viable alternative to conventional synthetic mouthwash CHX. This combination demonstrates reducing mean plaque scores and diminishing the levels of cytokines TNF-α, IL-α, and IL-β.

Body Image and Psychological Impact of Dental Appearance in Adolescents with Malocclusion: A Preliminary Exploratory Study

BACKGROUND

Body image and psychosocial functioning represent central challenges during adolescence and early adulthood. Malocclusion, defined as an irregularity in the alignment of the teeth, is known to negatively influence psychological outcomes. The current study aimed to elucidate the role of malocclusion, together with age, gender, and dental class, in body image and psychological functioning.

METHODS

A total of 126 participants aged from 12 to 19 years old (mean: 15.87, SD: 2.35, female participants: 52.4%, male participants: 47.6%) were recruited. Participants were visited at the University Hospital of Messina, Italy, and completed a sociodemographic questionnaire, the Body Image Concern Inventory (I-BICI), and the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ).

RESULTS

Significant correlations were found between age, dental class, the BICI, and the PIDAQ. In particular, age showed a positive and significant correlation with PIDAQ-total score. The correlations between occlusal status and the BICI variables were all significant and positive. All correlations between occlusal status and the PIDAQ variables were all significant and positive, except for dental self-confidence. The correlations between the variables of the PIDAQ and BICI instruments were all significant and positive, except for dental self-confidence, where the directions were significant and negative. Moreover, age, gender, and occlusal status predicted BICI and PIDAQ scores. Age was a positive predictor for PIDAQ self-confidence, gender for BICI and PIDAQ total scores, along with dysmorphic symptoms, social impact, psychological impact, and aesthetic concerns. Several significant gender differences were highlighted by the analyses, with higher scores in the female group on all the BICI variables, except symptom interference, and all the PIDAQ variables, except dental self-confidence.

CONCLUSIONS

Malocclusion appeared to play a central role in the psychological, representational, and psychosocial life of the participants. This research suggests that malocclusion and dental issues influence the psychological, representational, and psychosocial life of adolescents. Further research is required to examine the psychological impact of dental problems.

Relationship between aesthetic concern and self-esteem in adolescents with severe malocclusion

OBJECTIVE

This study aimed to evaluate the relationship between aesthetic concern and self-esteem in adolescents with severe malocclusion.

METHODS

A cross-sectional study developed with 543 adolescents from 11 to 13 years of age and severe malocclusion was selected. Dental aesthetic index (DAI) diagnosed the malocclusion and selected the groups with greater severity (DAI 3 and 4). Aesthetic concern was assessed using the oral aesthetic subjective impact scale (OASIS) and considered an outcome variable. The global negative self-evaluation (GSE) evaluated self-esteem. The variables were analysed using Poisson multiple regression and the model adjustment determined by the Akaike information criterion (AICC). The effect of each variable on OASIS was expressed as a prevalence ratio (PR) with 95% confidence intervals. The analyses were performed using the R program with a significance level of 5%.

RESULTS

A significant association was observed between aesthetic concern scores and self-esteem (p<.05). Individuals with low self-esteem had OASIS scores 14% higher (PR: 1.14; 95% CI: 1.08-1.21). There was no significant association between OASIS and gender and age (p>.05).

CONCLUSIONS

Self-esteem modulates how the individual perceives malocclusion. Adolescents with severe and very malocclusion and low self-esteem have greater aesthetic concerns.

Is the adolescent's esthetic concern associated with anterior occlusal conditions or the malocclusion severity level?

OBJECTIVES

To assess the esthetic impact of anterior occlusal conditions and malocclusion severity levels.

MATERIALS AND METHODS

A population-based cross-sectional study of 700 adolescents aged 15 to 19 years was conducted. The Oral Aesthetic Subjective Impact Scale (OASIS) was used to evaluate the subjective esthetic impact of malocclusion. The Dental Aesthetic Index (DAI) criteria were used to diagnose the anterior occlusal characteristics in isolation and the severity levels of malocclusion. The variables with P < .20 in the individual analyses were tested in multiple logistic regression models, and those with P < .10 remained in the model. The adjusted odds ratio (OR) was estimated with a 95% confidence interval (CI).

RESULTS

Of the adolescents, 42% showed negative self-perception of malocclusion. In addition, 15.4% of adolescents had severe malocclusion (DAI 3) and 18.9% very severe malocclusion (DAI 4). Crowding and spacing were shown to be 2.90 (CI: 2.06-4.09) and 2.53 (CI: 1.65-3.86) times, respectively, more likely to cause a negative esthetic impact in adolescents (P < .05). In addition, adolescents with orthodontic treatment need (DAI 2, 3, and 4) were more likely to report a negative esthetic impact (P < .05).

CONCLUSIONS

Anterior crowding and spacing are the conditions that most influence the esthetic concern of adolescents. Adolescents with very severe malocclusion and higher orthodontic treatment need are more likely to report a negative esthetic impact.

Novel Orthodontic Cement Comprising Unique Imidazolium-Based Polymerizable Antibacterial Monomers

White spot lesions (WSLs) can develop quickly and compromise the successful outcome of the orthodontic treatment. Orthodontic bonding cement with the capability to prevent or mitigate WSLs could be beneficial, especially for patients with high risk of caries. This study explored novel mono- and di-imidazolium-based polymerizable antibacterial monomers and evaluated orthodontic cement compositions comprising such novel monomers. Their antibacterial potentials, mechanical properties, and shear bond strength (SBS) to bovine enamel were investigated. Statistical tests were applied to SBS and mechanical tests (one-way ANOVA and Tukey’s test). For antibacterial resins C (ABR-C) and E (ABR-E), their minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against cariogenic Streptococcus mutans bacterial strain UA159 were found to be 4 μg/mL and 8 μg /mL, respectively. The loss of dry mass from completely demineralized dentin beams in buffer solutions pre-dipped into ABR-C and ABR-E resins is much less than that in control buffer (artificial saliva) only. For unfilled resins comprising up to 12 wt % ABR-C, no significant decreases in flexural strength or modulus were observed. For experimental cements incorporating 1–4 wt % ABR-C, there was no drastic compromise to the SBS to enamel except for 3 wt % ABR-C. Furthermore, their SBS was all comparable to the commercially available orthodontic cements. The ISO-22196 antimicrobial test against S. aureus showed significant levels of antibacterial effects—up to over 5 logs of microorganism reduction exhibited by ABR-C-containing experimental cements. The imidazolium-based polymerizable monomers could be utilized to functionalize orthodontic bonding cement with steady antibacterial activity and develop a potential strategy to counteract WSLs.

Factors related to the psychological impact of malocclusion in adolescents

To study the association between orthodontic treatment need and the psychosocial impact of dental aesthetics in a sample of adolescents, as well as other associated factors. A transversal study was conducted on 1,158 adolescents (12–16 years old) examined at the schools selected for the 2018 epidemiological study on oral health in the Comunidad Valenciana (Spain). The need for orthodontic treatment was determined by DAI and IOTN. The psychosocial impact was established by the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Other variables considered were sex, social class, DMFT index and Body-Mass Index, and having previously worn or presently wearing an orthodontic device. A lineal regression statistical technique was applied to study the significant associations with the scoring obtained in PIDAQ. The PIDAQ scores revealed a significant and positive lineal relationship with regard to need for orthodontic treatment: DAI (ẞ = 0.20) and IOTN-DHC (ẞ = 4.87), in women (ẞ = 2.66) and a negative one for having previously worn an orthodontic device (ẞ = − 5.74). The rest of the variables had no statistical significance (p > 0.05). The psychosocial impact of dental aesthetics in adolescents is associated with the presence of malocclusion and the female sex, while the condition of having previously worn an orthodontic device reduces the psychosocial impact.

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

OBJECTIVE

To evaluate the effects of nonextraction and all first premolar extraction modalities of orthodontic treatment on oral health-related quality of life (OHRQoL) among adolescents.

MATERIALS AND METHODS

Sixty-eight adolescents of aged 12-18 years were chosen. Subjects who required nonextraction orthodontic treatment were included in group I, and those who required all first premolar extractions for orthodontic treatment were included in group II. Baseline OHRQoL data (T0) were recorded before the start of treatment. To evaluate the impact of orthodontic treatment on OHRQoL, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was presented to all subjects for retrospective evaluation at 1 month (T1), 3 months (T2), 6 months (T3) and 1 year (T4) after the start of orthodontic treatment and 1 week after completion of orthodontic treatment (T5).

RESULTS

At T1 and T2, the physical pain and physical disability domains of OHIP-14 were impacted significantly by comprehensive orthodontic treatment in both groups (P < .001). The negative impact of orthodontic treatment on OHRQoL was maximum at T1 and then slowly recovered to the pretreatment level at T3 in both groups. Recovery of OHIP-14 scores was relatively faster in group I subjects compared to group II subjects. At T1 and T2, social disability and handicap domains were deteriorated significantly in group II subjects compared to group I subjects (P < .01).

CONCLUSIONS

The severity of OHRQoL deterioration was similar in both modalities of orthodontic treatment, but recovery from negative impacts was relatively slower in the first premolar extraction subjects.

A biopsychosocial-cultural model for understanding oral-health-related quality of life among adolescent orthodontic patients

Background

Based on previous theoretical oral-health-related quality of life (OHRQoL) models and most recently framework, as well as sociocultural model of body image dissatisfaction, the current study aimed to investigate the effect of individual (dental aesthetics and dental appearance social comparison) and sociocultural factors (social reinforcement from parents, peers and mass media on dental aesthetics) as well as their interaction on psychosocial dimension of OHRQoL among adolescent orthodontic patients.

Methods

In this cross-sectional study comprising 427 adolescent orthodontic patients (151 boys and 276 girls) aged between 11 and 16 years old, the psychosocial dimension of OHRQoL was measured by Psychosocial Impact of Dental Aesthetics Questionnaire. Individual predictor of dental aesthetics was defined by the Aesthetic Component of the Index of Orthodontic Treatment Need, and dental appearance social comparison was assessed by four items adapted from Physical Appearance Comparison Scale. Sociocultural predictor of social reinforcement was measured by six items adapted from Perceived Sociocultural Pressure Scale. Spearman correlations, path analyses, and structural equation modeling were used to build up several predictive models.

Results

As hypothesized, two direct pathways were observed that patients’ dental aesthetics and all three sources of social reinforcement directly predicted the psychosocial dimension of OHRQoL. Meanwhile, we observed one indirect pathway, that three sources of social reinforcement predicted the psychosocial dimension of OHRQoL, in part, through dental appearance social comparison.

Conclusions

This study provides preliminary evidence indicating that dental aesthetics, social reinforcement and dental appearance comparison are reliable predictors of psychosocial dimension of OHRQoL among adolescent orthodontic patients.

Adherence to Dietary Advice and Oral Hygiene Practices Among Orthodontic Patients

INTRODUCTION

Adherence to dietary advice and proper oral hygiene practices during orthodontic treatment are critical to maintaining good oral health and achieving successful treatment results. Thus, understanding patients' habits and practices before, during, and after orthodontic treatment is needed to ensure better oral health-related behavior among these patients.

PURPOSE

To investigate sugar-related dietary habits, visits to dental hygienists and dentists, and oral hygiene practices among patients during orthodontic treatment and after treatment compared to patients before treatment.

METHODS

A cross-sectional self-administered survey collected data from 375 patients (aged 10 years and older) from the Orthodontic Department at King Abdulaziz University Dental Hospital, Jeddah, Saudi Arabia. Patients were grouped according to their history of receiving orthodontic treatment into: patients before orthodontic treatment, patients during treatment, and patients after treatment. The survey assessed sugar-related dietary habits, frequency of visits to hygienists and dentists, and oral hygiene practices.

RESULTS

Patients during orthodontic treatment and those after treatment were less likely to eat sticky food compared to patients before treatment (OR=0.4, 95% CI=0.2-0.9 and OR=0.5, 95% CI=0.3-0.9, respectively). No significant differences were found in the odds of dental visits among the groups. Compared to patients before orthodontic treatment, patients during treatment and patients after treatment had higher odds of tooth brushing twice or more per day (OR=4.8, 95% CI=1.7-14.3, and OR=4.0, 95% CI=1.2-13.6, respectively) and were more likely to brush for an adequate time (OR=2.6, 95% CI=1.6-4.4 and OR=1.9, 95% CI=1.0-3.5, respectively). Moreover, the likelihood of flossing once daily was higher in patients during treatment and in patients after treatment relative to those before treatment. However, only patients during orthodontic treatment used interdental brushes more than patients before treatment.

CONCLUSION

Patients' oral health-related behavior seems to improve during and after orthodontic treatment. The findings of this study suggest that orthodontists can play a role in improving oral hygiene practices among their patients. More reinforcement of dietary instructions and periodic dental and hygiene visits is needed during orthodontic follow-up appointments.
