RESUMEN

INTRODUCTION: Determination of improvement in orthodontic treatment may depend on the measurement method used and the purpose. METHODS: Improvement after orthodontic treatment (from T1 to T2 [beginning to end of treatment]) was assessed 3 ways from a set of 98 patient records: (1) calculated by subtracting judges' assessments at T2 from T1 for records presented in random order, (2) judged as a holistic impression viewing T1 and T2 records side by side, and (3) determined from proxies (American Board of Orthodontics Discrepancy Index, the American Board of Orthodontics Objective Grading System, and the Peer Assessment Rating index). RESULTS: High levels of intramethod consistency were observed, with intraclass correlation coefficient clustering around an intraclass correlation coefficient of 0.900, and distributions were normal. Calculated and judged improvements correlated at r = 0.606. Calculated or judged improvements were correlated at a lower level with proxies. Calculated improvement was significantly associated with "challenge" (T1) scores and judged improvement associated with "results" (T2) scores. Common method bias was observed, with higher correlations among similar indexes than among indexes at the same time that used various methods. Relative to differences in Peer Assessment Rating scores, calculated improvement overestimated low scores and underestimated high ones. The same effect, but statistically greater, was observed using direct judgment of improvement. CONCLUSIONS: These findings are consistent with decision science and measurement theory. In some circumstances, such as third-party reimbursement and research, operationally defined measures of occlusion are appropriate. In practice, the determination of occlusion and improvement are best performed by judgment that naturally corrects for biases in proxies and incorporates background information.

RESUMEN

BACKGROUND: The aim of this study was to determine the retention practices following orthodontic treatment in a tertiary health institution in Nigeria. METHODS: A retrospective study conducted in the Orthodontic Clinic of the Lagos University Teaching Hospital over a 3-year-period. Data on the type of retainers used and the retention practices in the upper and lower arches were obtained from case files of patients who had completed orthodontic treatment in the institution. Statistical analysis was performed using IBM SPSS software version 23. RESULTS: The demographic variables comprised of 136 subjects; 93 females (68.4%) and 43 males (31.6%). Their ages ranged from 9-44 years with a mean age of 18.96 ± 6.75. Class I malocclusion was the most common malocclusion pattern (84.6%), followed by Class II (10.3%) and Class III (5.1%). Removable retainers were more commonly used and accounted for retention carried out in 85.3% of the study population. There was a preference for the use of removable retainers in the upper arch; the Hawley retainer being the most used (79.4%). In the lower arch however, no form of retention was carried out for majority of the patients after orthodontic treatment (86.8%). However, when done, the fixed lingual retainer was the most frequently used (13.2%). CONCLUSION: The Hawley retainer was the predominant retainer in this study. The fixed lingual retainer was the most frequently used in the lower arch. Longitudinal studies are required to determine efficacy of different types of retention following orthodontic treatment.

RESUMEN

Introduction: patients´ satisfaction with their dental appearance and tooth colour is often influenced by certain factors which need to be addressed periodically among different populations. Methods: a self-administered questionnaire consisting of sociodemographic data, questions on patients´ satisfaction with tooth colour, perceived malalignment of teeth, non-aesthetic anterior tooth-coloured restoration and presence of tooth fracture were distributed. Data collected was analysed using Statistical Package for Social Sciences (IBM, SPSS version 20). Chi square was used to test the statistical differences at a significance of p> 0.05. Results: a total of 410 patients (M=147, F=263) participated in the study. About 73% had tertiary education while 36.3% were within the modified ISCO-08 Group 2. The respondents that were satisfied with the general dental appearance and tooth shade were 66.3% and 63.5% respectively. More males (65.1%) than females (62.7%) were satisfied with tooth colour while more females (69.1%) were satisfied with dental appearance. The older age group were more satisfied with dental appearance and tooth colour. Awareness of tooth whitening (Over 80%) and the desire to undergo tooth whitening was more among the post-secondary individuals. More of dental patients (73.1%) than medical (59.2%) were satisfied with teeth appearance (p=0.003). Conclusion: patients are increasingly aware of their dental appearance/tooth colour and the need to improve it with tooth bleaching and/or orthodontic treatment. Female were more dissatisfied with their tooth colour but more satisfied with their dental appearance than the male. Older people were more satisfied with their dental appearance and tooth colour compared to younger age group.

RESUMEN

ABSTRACT: This retrospective study aimed to explore the effect of orthodontic treatment (ODT) on anterior tooth displacement (ATD) caused by periodontal disease (PD).A total of 72 patients were selected and were divided into a control group (n = 36) and an experimental group (n = 36). Patients in both groups received conventional periodontal treatment. In addition, patients in the experimental group also received ODT. Outcomes include probing depth, percentage of bleeding sites, clinical attachment loss, clinical crown length, tooth root length, and periodontal tissue of the affected tooth (alveolar bone height, periodontal pocket depth, bleeding index).After treatment, the patients in the experimental group achieved more improvements in probing depth (P < .01), percentage of bleeding sites (P < .01), clinical attachment loss (P < .01), clinical crown length (P = .04), and periodontal tissue of the affected tooth (periodontal pocket depth (P < .01), and bleeding index (P < .01)), than those of patients in the control group.This study suggests that ODT is beneficial for ATD caused by PD. Future studies are still needed to verify the findings of this study.

RESUMEN

Digital technologies are gradually integrating our orthodontic practices and retainers, often less considered compared to active devices, are also benefiting. The author will give in this article a brief presentation of the various current possibilities offered by the use of digital tools for carrying out and monitoring fixed or removable retention methods. The digital workflow is perfectly suited to the production of modern and durable retainers, whether for fixed or removable devices, as well as their long-term monitoring. The objective is not to decide on the superiority of one system over another, but to expose all the possibilities for adapting the digital tool to the orthodontist's method of retention. The benefit of using digital technology is saving time and improving performance, minimizing unnecessary manipulation and improving device precision. Digital technology provides all the elements necessary to achieve new generation retainers both more simply, and for them to be more precise and more durable. These technologies are in constant progress and we can still consider improvements in the near future as software and hardware developments progress.

RESUMEN

We designed this study to determine the efficiency and stability of anterior segmental osteotomies (ASO) without orthodontics for various dentofacial deformities. Records of patients treated with maxillary or mandibular ASO, or both, without orthodontics in the past 15 years were analysed. The assessment included postoperative analysis of patients' aesthetics and functional satisfaction using a questionnaire and grading (score 0 - 4) system, and the amount of relapse calculated from 12-month postoperative cephalograms. A total of 26 ASO subjects (age range 13- 31 years) were studied (14 maxillary, two mandibular, and 10 bimaxillary). Long-term stability was acceptable in all cases with no significant relapse (p>0.05). No major complications were encountered. All patients reported good to excellent (score=3 to 4) satisfaction following surgery. Using meticulous planning and a careful surgical technique, ASO without orthodontics is a simple, quick, safe, and stable option for the correction of dentofacial deformities.

RESUMEN

Background: To correlate the need for orthodontic treatment between the self-perception of Chilean adolescents from 14 to 18 years old with the observation of a dentist using the same assessment scale, as well as to determine if covariates such as gender, age and type of school influence the self-perception of the adolescent and the examiner. Material and Methods: Cross-sectional descriptive study of adolescents aged 14 to 18 years from public, subsidized and private schools in Temuco, Chile. The probability sample is stratified by course, from first to fourth year, a total of 414 students participated, according to the eligibility criteria. The photographic score of the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used. The statistical analysis of the data was performed with the SPSS Statistics program v.23. Results: 94.9% of the adolescents perceived themselves as having good aesthetics. The examiner considered that 77% presented this condition, p<0.00. Males perceived themselves better than females. At age 15, 1.7% of students considered themselves to have poor aesthetics, p<0.01. From the examiner's perspective, aesthetics are related to type of school, p<0.00. Conclusion: Adolescents perceive themselves better aesthetically than do the evaluators. The school type factor, according to the IOTN-AC examiner, shows a higher proportion of students with no need for orthodontic treatment in private schools, and a threshold need in municipal and subsidized institutions.


Correlacionar la necesidad de tratamiento ortodóncico, entre la autopercepción de adolescentes con el diagnóstico de un evaluador odontólogo, utilizando la misma escala de valoración, así también determinar si las variables como el género, la edad y la dependencia educacional influyen en la autopercepción del adolescente y la observación del examinador. Material y Métodos: Estudio descriptivo de corte transversal, en adolescentes de 14 a 18 años de escuelas públicas, subvencionadas y privadas de Temuco-Chile. Muestreo probabilístico estratificado por cursos, de primero a cuarto medio con una muestra de 414 estudiantes, según los criterios de elegibilidad. Se utilizó el score fotográfico del componente estético (AC) del Índice de Necesidad de Tratamiento de Ortodoncia (INTO). El análisis estadístico de los datos fue realizado con el programa SPSS Statistics v.23. Resultados: El 94,9% de los adolescentes se autoperciben con una buena estética, el examinador considera que un 77% presenta esta condición, p<0,00. Los varones se perciben mejor que las damas. Los adolescentes de 15 años un 1,7% considera tener mala estética, p<0,01. Desde la perspectiva del examinador la estética se relaciona con la dependencia educacional, <0,01. Conclusión: Los adolescentes se autoperciben mejor estéticamente que lo diagnosticado por evaluadores odontólogos. El factor dependencia educacional según INTO-AC examinador, muestra mayor proporción de estudiantes sin necesidad de tratamiento ortodóncico en los establecimientos privados, y necesidad límite en los públicos y subvencionados.

RESUMEN

INTRODUCTION: The primary aim was to compare patients' and parents' orthodontic treatment expectations at the Eastman Institute for Oral Health, University of Rochester, Rochester, NY (UR) in the United States. Secondary aims were to assess the association between sociodemographic factors and UR participants' expectations; and compare participants' expectations between UR, Academic Centre for Dentistry Amsterdam (ACTA) and King's College Dental Hospital, London, United Kingdom (KC) (previously published data). METHODS: One hundred and forty participants [70 patients and one of their parents (n = 70)] completed a validated questionnaire (10 questions) to measure orthodontic treatment expectations before screening at the Orthodontic Department at UR. Various sociodemographic factors were assessed. The paired t test (for continuous responses) and the Fisher exact test (for categorical responses) were used to compare UR patients' and parents' responses. Two-sample t test and the Fisher exact test were used to compare participants' responses among sociodemographic groups. One-way analysis of variance followed by the Tukey test, and the Fisher exact test were used to compare participants' responses between UR, and ACTA and KC (data collected from previous publications). A multiplicity correction was performed to control the false discovery rate. RESULTS: Patients at UR expected less check-up and diagnosis, and less discussion about treatment at the initial visit, more dietary restrictions, and less improvement in smile esthetics and social confidence with orthodontic treatment than parents. Participants' responses differed by sociodemographic factors at UR and between UR, ACTA, and KC. CONCLUSIONS: Expectations of orthodontic treatment differ between patients and their parents, are associated with sociodemographic factors, and vary among United States and European University centers.

RESUMEN

Aims: This study aimed to assess parents' awareness and attitude regarding their children's malocclusion compared with professional assessments and to measure the prevalence of malocclusion among children in Dammam, Saudi Arabia. Methods: The study population consisted of 377 randomly selected children (aged 8-12 years) from five schools in Dammam, Saudi Arabia. A questionnaire was used to assess parents' awareness using the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) and knowledge about preventive orthodontics. A clinical examination was performed by two calibrated examiners to measure the prevalence of malocclusion using both the AC and dental health component (DHC) of IOTN. Results: The most common Angle's molar relationship was Class I (78.2%), followed by Class II (17.5%) and Class III (4.2%). The DHC (score 3-5), which indicated the need for orthodontic treatment, was 55.4%. There was a significant difference (P < 0.05) between AC from examiners and parents, whereby the parents tended to underestimate their children's malocclusion by a factor of 1.45. Surprisingly, many parents (67.4%) lacked knowledge about preventive orthodontics. Conclusions: Class I malocclusion was most prevalent among children in the area of Dammam. A moderate percentage (55.4%) of the study subjects required treatment based on the DHC. Based on the lack of knowledge about preventive orthodontics in the majority of parents in our study, it is recommended that oral health-promoting programs be implemented to improve the awareness of malocclusion in the region.

RESUMEN

INTRODUCTION: The study investigated which patient and orthodontic treatment factors act as predictors for the conclusion of the ongoing treatment in a dental clinic of a specialization program in Orthodontics. METHODS: Data were collected from the records of patients treated from 1997 to 2015. Potential predictors for treatment conclusion were investigated: patient-related factors (PRFs) and treatment-related factors (TRFs). PRFs were sex, age, face balance, Angle malocclusion classification, open bite, denture, facial pattern, facial profile, buccal corridor, crossbite, maxillary deficiency, and sagittal mandibular behavior; and TRFs were therapeutic approaches, treatment modality, extractions, and Bolton discrepancy. The initial and final treatment dates were collected. Descriptive data analysis, univariate, and multivariate logistic regression were performed (5% significance). RESULTS: Of the 903 records, 561 patients were included in the study. It was demonstrated that starting the treatment at a young age (PRF) and the presence of crossbite (TRF) are predictive factors for the treatment conclusion. A vertical facial pattern (dolichofacial or brachyfacial) and a greater number of extractions for orthodontic reasons may contribute positively to the conclusion of the treatment. The frequency of treatment inconclusion was higher during the first 2 years of treatment (more than 50% of the patients that initiated the treatment). CONCLUSIONS: Young age at the beginning of treatment and the presence of crossbite malocclusion can increase the chance of treatment conclusion.

RESUMEN

BACKGROUND: Retention of the maxillary anterior teeth is commonly recommended to maintain the teeth in their corrected positions. Both fixed and removable retention methods are used, but the certainty of evidence is low. OBJECTIVE: To evaluate post-treatment changes in irregularity of the maxillary six anterior teeth and single tooth contact point discrepancy (CPD) of three different retention methods. TRIAL DESIGN: Three-arm parallel group single-centre randomized controlled trial. MATERIALS AND METHODS: Ninety patients, 54 girls and 36 boys, were recruited to the study. The inclusion criteria were adolescent patients treated with fixed appliances at least in the maxilla. After gaining informed consent from the patient and their custodians, the patients were randomized to one of three groups: bonded retainer 13-23, bonded retainer 12-22, and removable vacuum-formed retainer (VFR) covering the maxillary teeth including the second molars. The randomization, prepared by an independent person, used blocks of 30. The primary outcomes were changes in single CPD and Little's irregularity index (LII) measured on digitalized three-dimensional study casts before and after 2-year retention. The study casts were anonymized before assessment and the changes were blinded for the assessor. Data were evaluated on an intention-to-treat basis. Thus, all randomized patients were incorporated into the final analysis. RESULTS: The LII and CPDs increased slightly in all three groups without any statistically significant differences between the groups. The VFR group showed a small intercanine width increase and some more changes of canine rotations than in the other groups. HARMS: No harm was observed in any subjects and none of the patients needed retreatment. LIMITATIONS: The trial was a single-centre study and short-term changes were evaluated. CONCLUSIONS: All three retention methods showed equally effective retention capacity and all the changes found in the three groups were small and considered clinically insignificant. Thus, the null hypothesis was confirmed. All three methods can be recommended. TRIAL REGISTRATION: NCT04616755.

RESUMEN

OBJECTIVES: To compare the effects of Forsus appliances with and without temporary anchorage devices (TADs) for patients with skeletal Class II malocclusion. MATERIALS AND METHODS: Through a predefined search strategy, electronic searching was conducted in PubMed, Embase, Web of Science, CENTRAL, ProQuest Dissertations & Theses, and SIGLE with no language restrictions. Eligible study selection, data extraction, and evaluation of risk of bias (Cochrane Collaboration tool) were conducted by two authors independently and in duplicate. Any disagreement was solved by discussion or judged by a third reviewer. Statistical pooling, sensitivity analysis, subgroup analysis, and assessment of small-study effects were conducted by using Comprehensive Meta-Analysis and Stata 12.0. Heterogeneity was analyzed for different types of study designs, TADs, and radiographic examinations. RESULTS: Electronic search yielded a total of 256 studies after removing duplicates. Among them, six studies were finally included. All articles were of high quality. The pooled mean differences were -0.27 (95% confidence interval [CI]: -0.59, 0.05) for SNA, 0.58 (95% CI: -0.07, 1.23) for SNB, -0.86 (95% CI: -1.74, -0.03) for ANB, 1.63 (95% CI: 0.46, 2.80) for Co-Po, 0.75 (95% CI: 0.28, 1.23) for SN-MP, -7.56 (95% CI: -11.37, -3.76) for L1-MP, 0.47 (95% CI: -0.98, 1.91) for overjet, 0.39 (95% CI: -0.57, 1.35) for overbite, -1.84 (95% CI: -5.15, 1.47) for SN-OP, and 4.97 (95% CI: -1.22, 11.17) for nasolabial angle. CONCLUSIONS: TADs (especially miniplates) were able to eliminate dental adverse effects of Forsus appliances for correction of skeletal Class II malocclusion.

RESUMEN

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.

RESUMEN

The first publication on the use of magnets in dentistry for stabilizing prosthetics on implants dates back to 1953. Clinical development in orthodontics, without having experienced a real boom, has increased over the past ten years, in parallel with the improvement of the device. The objective of this review of the literature is to synthesize clinical applications and reported iatrogenic effects. A systematic review of the international literature from the Pubmed and Cochrane databases from 1999 to July 2018 was conducted which resulted in 36 articles. The factors studied are the indications and contraindications, the means or procedure, as well as the iatrogenic effects. Original cases are presented. The correction of infraclusions is the main indication, followed by the correction of anteroposterior malocclusions and then the correction of over-erupted teeth. Traction of an impacted teeth and diastema closure have not been found in recent publications probably because of the low benefit-risk ratio. The future no longer seems to be buried magnets or left in the long term in the mouth considering there seems to be concerns in terms of toxicity (or even the risk in terms of vital prognosis). The magnets could offer interesting perspectives to manage the current limits of the aligners, the movements of anterior egression, rotation and previous torque being still problematic...

RESUMEN

BACKGROUND: Angle class II malocclusion is clinically complex and common malocclusion type, which affects beauty. Conventional treatment has the disadvantages of long course of treatment, high cost, easy recurrence and limited curative effect. Clinical practice shows that micro-implant anchorage has certain advantages in the treatment of Angle II malocclusion, but lacks the evidence of evidence-based medicine. This study systematically evaluates the efficacy and safety of micro-implant anchorage in the treatment of Angle class II malocclusion. METHODS: A systematic search was performed by retrieving on English databases (PubMed, Embase, Web of Science, and the Cochrane Library) and Chinese databases (CNKI, Wanfang, Weipu [VIP], CBM). Besides, manually search for Google and Baidu academic of micro-implant anchorage in the treatment of Angle class II malocclusion in randomized controlled clinical research. The retrieval time limit was from the establishment of the database to September 2020. Two researchers independently extracted and evaluated the quality of the data in the included study. A meta-analysis was performed using RevMan5.3 software. RESULTS: In this study, the efficacy and safety of micro-implant anchorage against Angle class II malocclusion were evaluated by SNA, BNA, ANB, NLA°, Adverse reaction. CONCLUSIONS: This study will provide reliable evidence-based evidence for the clinical application of micro-implant anchorage in the treatment of Angle class II malocclusion. ETHICS AND DISSEMINATION: Private information from individuals will not be published. This systematic review also does not involve endangering participant rights. Ethical approval was not required. The results may be published in a peer-reviewed journal or disseminated at relevant conferences.OSF Registration number: DOI 10.17605/OSF.IO/UPBR8.

RESUMEN

The objective of this comparative retrospective cohort performed on 202 patients was to evaluate the influence of instrumental extraction (forceps, suction cup, spatula) during delivery on the need for orthodontic treatment. Questionnaires on the type of delivery were distributed in three different structures. The need for treatment was assessed using the IOTN indicator (Index of Orthodontic Treatment Need). The groups were compared by statistical tests at the significance level of 5 %. 202 patients were included (51 in the group « instrumental delivery ¼, 151 in the control group). With an average IOTN of 3.3 in the « instrumental delivery ¼ group versus 2.5 in the « non-instrumental delivery ¼ group, the difference between the two groups is statistically significant (p = 0.00015). Since the need for orthodontic treatment is significantly higher in patients born by instrumental delivery compared to patients born without instrumental support, instrumental extraction is therefore a risk factor in orthodontics, diagnosis and orthodontic treatment may be indicated in these patients. In addition, provided that it is proven effective, early osteopathic management may be recommended.

RESUMEN

La evolución de la ortodoncia, desde sus inicios, ha demostrado hechos destacables como el surgimiento de la técnica de arco recto, el desarrollo de prescripciones variadas, el uso de ranuras con diferentes dimensiones, sistemas de anclaje esquelético, tomografía... A pesar de ello, los diseños y las características que presentaban los brackets eran siempre los mismos y limitados. La historia de las grandes ideas es vasta, pero debían estar unidas en una sola pieza. Esto es lo que hicieron los autores de este artículo, al desarrollar un nuevo diseño de bracket que cuenta con dos slots centrales y cada una con diferentes dimensiones, un slot tiene dimensiones de 0.018 "X 0.030" y el otro 0.022 "X 0.028", abriéndse una gama de posibilidades. A partir de ahora contamos con una herramienta de trabajo con varios recursos, que genera grandes beneficios para profesionales y pacientes, y que gana cada día más seguidores (AU)


The evolution of orthodontics, since its beginnings, has demonstrated remarkable events such as the appearance of the straight wire technique, the development of varied prescriptions, the use of slots with different dimensions, skeletal anchoring systems, tomography ... Despite this, the designs and the features that the brackets presented were always the same and limited. The history of great ideas is vast, but they needed to be united in one piece. This is what the authors of this article did, when developing a new bracket design that features two central slots and each with different dimensions, one slot has dimensions of 0.018 "X 0.030" and the other 0.022 "X 0.028" with a fan of possibilities is being opened. Now, a work tool with several resources, which generates great benefits for professionals and patients is gaining more followers every day (AU)

RESUMEN

BACKGROUND: Myofunctional condition of the temporomandibular joint (TMJ) in everyday orthodontic practice is an important diagnostic criterion for evaluating the quality of orthodontic treatment. Pre-orthodontic preparation is often a necessary stage of orthodontic treatment. OBJECTIVE: To evaluate and compare the adaptation of the masticatory muscles of patients during pre-orthodontic preparation based on interference electromyography of the masticatory and temporal muscles with the data of patients after orthodontic treatment without preparation and with the indicators in the control group. MATERIALS AND METHODS: Electromyography indicators of the masticatory and temporal muscles of 82 patients aged 18 to 35 were obtained. Patients were divided into 3groups: 1st - with signs of TMJ dysfunction at the stage of pre-orthodontic preparation and orthodontic treatment; 2nd - patients after orthodontic treatment, having dissatisfaction with the state of the dentition; 3rd - a control group was compared composed of patients without signs of myofunctional dysfunction. RESULTS: Patients who have complaints after orthodontic treatment have different electromyography of the masticatory and temporal muscles in comparison with the control group. In patients with signs of TMJ dysfunction at the stage of preorthodontic preparation, after using a device of their own design, the structures of the temporomandibular joint were adapted to a new functional position. CONCLUSION: After using the device of its own design, myofunctional adaptation to a new functional position was obtained, which is confirmed by electromyographic studies.

RESUMEN

INTRODUCTION: The purpose of this research was to evaluate the esthetic impact of orthodontic treatment need in adolescents. METHODS: This cross-sectional study was performed with 1172 adolescents aged 12 (n = 638) years and 15 (n = 534) years from Salvador, Bahia, Brazil. The esthetic impact was the following outcome variables: Aesthetic Component of the Index of Orthodontic Treatment Need and the Oral Aesthetic Subjective Impact Scale. The normative orthodontic treatment need was assessed by the Dental Health Component of the Index of Orthodontic Treatment Need (IOTN-DHC) and by the Dental Aesthetic Index (DAI). Logistic regression models were adjusted, estimating crude odds ratio with the respective 95% confidence intervals. The variables with P ≤0.20 in the individual analyses were tested in multiple logistic regression models, remaining the variables with P ≤0.05. RESULTS: The results showed a statistically significant association for the esthetic impact (Aesthetic Component of the Index of Orthodontic Treatment Need and the Oral Aesthetic Subjective Impact Scale) when assessing the normative orthodontic treatment need by the DAI (P <0.05). However, there was no significant association between subjective esthetic impact and normative needs when using the IOTN-DHC (P >0.05). CONCLUSIONS: DAI was more associated with the adolescents' esthetic concern than IOTN-DHC and should be the Index of Orthodontic Treatment Need to be selected to complement the patient's self-perception.
