Perceived Orthodontic Needs and Attitudes towards Early Evaluation and Interventions: A Survey-Based Study among Parents of Italian School-Aged Children.

(1) Background: Parents' awareness of malocclusion and their attitude towards early evaluation and interventions influence children's orthodontic management. This cross-sectional study investigates factors that affect the perceived orthodontic needs and the attitude towards interceptive orthodontics among a sample of one-thousand eight-hundred and six (1806) parents of children aged between 6 and 11 years. (2) Methods: The investigation was carried out thought a 18-items online questionnaire divided as follows: characteristics of respondents; perceived child's orthodontic needs; attitude toward early orthodontic evaluation and interventions. The associations between responses were assessed with a Chi-square test. (3) Results: Two-thirds of the respondents referred to having consulted an orthodontist for their child, and more than half of them initiated the required orthodontic treatment. In 44% of cases, the orthodontic consultation occurred after the age of 7 years. Parents' higher education and history of orthodontic treatment were associated with a greater awareness of orthodontic needs. Parents' perception of the impact of teeth on their child's personality was significantly associated with the decision to start the orthodontic treatment (p < 0.001). (4) Conclusions: Although the parents' level of awareness of their child's orthodontic needs was generally satisfactory, the results of the present study pointed out the need for a better education regarding the importance of an early orthodontic assessment.

An epidemiological study on early orthodontic treatment need among eastern Saudi Arabian children in the mixed dentition stage.

Estimation of early orthodontic treatment need among children is essential for planning orthodontic interventions in the mixed dentition stages thereby reducing the burden in a publicly funded healthcare system. The present study aimed to assess the early orthodontic treatment need among children with mixed dentition in the Eastern Saudi Arabia. A descriptive cross-sectional study was conducted among Saudi children visiting the outpatient clinics in a University dental setting, and data were collected based on Index for preventive and interceptive orthodontic need (IPION). Descriptive statistics, chi-square test and Fisher's exact test were used for data analysis with statistical significance set at p < 0.05. The category of 'no treatment need' accounted for 11.3% while 'moderate treatment need' and 'definite treatment need' categories accounted for 29.3% and 59.4% respectively. There was no statistical difference between males and females in the distribution of the three categories of treatment need (p = 0.513). This study demonstrated a very high need for early orthodontic treatment among Saudi children in the mixed dentition stage. Emphasis should be placed on increased awareness and benefits of seeking early orthodontic treatment involving preventive and interceptive procedures in the mixed dentition.

The effect of micro-osteoperforations on the rate of maxillary incisors' retraction in orthodontic space closure: a randomized controlled clinical trial

BackgroundThis single-centered randomized controlled clinical trial aimed to evaluate the effectiveness of micro-osteoperforations (MOPs) in accelerating the orthodontic retraction of maxillary incisors.MethodsForty-two patients aged 16–40 were recruited and randomly assigned into two groups, one which underwent MOPs (MOPG) in the buccal and palatal region of all maxillary incisors immediately before the start of retraction and one which did not (CG). Eligibility criteria included the orthodontic need for maxillary first premolars extraction and space closure in two phases. The primary outcome of the study consisted of measuring the rate of space closure and, consequently, the rate of incisors’ retraction using digital model superimposition 14 days later and monthly thereafter for the next 4 months. The secondary outcomes included measuring anchorage loss, central incisors’ inclination, and root length shortening, analyzed using cone beam computed tomography scans acquired before retraction and 4 months after retraction. Randomization was performed using QuickCalcs software. While clinical blinding was not possible, the image’s examinator was blinded.ResultsTwenty-one patients were randomly assigned to each group. However, due to various reasons, a total of 37 patients (17 male and 20 female) were analyzed (mean age: 24.3 ± 8.1 years in the MOPG; 22.2 ± 4.2 years in the CG) during the trial. No statistically significant difference was found between the MOPG and the CG regarding the incisors’ retraction measured at different time points at the incisal border (14 days, 0.4 mm vs. 0.5 mm; 1 month, 0.79 mm vs. 0.77 mm; 2 months, 1.47 mm vs. 1.41 mm; 3 months, 2.09 mm vs. 1.88 mm; 4 months, 2.62 mm vs. 2.29 mm) and at the cervical level (14 days, 0.28 mm vs. 0.30 mm; 1 month, 0.41 mm vs. 0.32 mm; 2 months, 0.89 mm vs. 0.61 mm; 3 months, 1.36 mm vs. 1.10 mm; 4 months, 1.73 mm vs. 1.39 mm). Similarly, no statistically significant differences were detected in the space closure, anchorage loss, central incisors’ inclination, and radicular length between groups. No adverse effect was observed during the trial.ConclusionsMOPs did not accelerate the retraction of the maxillary incisors, nor were they associated with greater incisor inclination or root resorption.Trial registration ClinicalTrials.gov NCT03089996.

The Prevalence of Malocclusion among Sixand Nine-year-old School-going Children of Visakhapatnam: A Cross-sectional Study

Introduction: Malocclusion profoundly impacts a child’s emotional well-being and affects an individual’s quality of life. Early identification improves the chances of organising preventive and interceptive treatment to limit the intensity of developmental aberrations. The data for malocclusion among children of Visakhapatnam is lacking. Aim: To study and evaluate the prevalence of malocclusion and ascertain gender dimorphism among six- and nine-year-old school-going children of Visakhapatnam. Materials and Methodols: A cross-sectional, double-stage sample study was conducted among 616 school-going children of Visakhapatnam, Andhra Pradesh, India, by a single calibrated examiner using a modified Index for Preventive and Interceptive Orthodontic Needs (IPION). IBM Statistical Package for the Social Sciences (SPSS), version 25.0, was used to analyse data and Pearson’s chi-square test to elicit gender differences in the prevalence of malocclusion traits. Results: Prevalence among six-year-old children: interproximal caries-38.4%, premature tooth loss-10.1%, supernumerary teeth-0.3%, upper molar rotation-0.3%, lower molar tipping-2%, anterior crossbite-2.7%, posterior crossbite-0.7%, overjet more than 3 mm-5.1%, overbite more than 2/3rd-8.4%, open bite-2%, incompetent lips-13.8%. Prevalence among nine-year-old children: interproximal caries-49.5%, premature tooth loss-8.8%, active frenum-2.8%, supernumerary teeth-0.6%, diastema-3.4%, upper molar rotation-2.2%, lower molar tipping-5%, impended eruption of first permanent molar-1.3%, overjet more than 3 mm11%, overbite more than 2/3rd-12.5%, open bite-2.2%, anterior crossbite-8.2%, posterior crossbite tendency-3.1%, Class I-75.6%, Class II-18.8%, Class III (functional shift)-0.6%, Class III (no functional shift)-3.76%, incompetent lips-16.3%. Conclusion: Children from both cohorts demonstrated malocclusion traits. The nine-year-old group had greater prevalence for all components examined except premature tooth loss. No statistically significant gender dimorphism was found in both cohorts.

NHS orthodontic services in Wales: orthodontic workforce distribution and primary care commissioned activity in 2021.

Objectives 1) To ascertain the volume of primary care orthodontic activity commissioned within Wales and compare this to the 12-year-old population; and 2) To ascertain the orthodontic workforce undertaking NHS orthodontic provision within Wales and their distribution.Methods Information was gathered between September and November 2021 from multiple sources within Wales, including: Freedom of Information requests; Welsh Government statistics; orthodontic professional networks; orthodontic provider websites; health boards (HBs); and directors of primary care/contracting/commissioning.Results The HBs had varying levels of orthodontic need and commissioned activity with a significant amount of cross border activity in South Wales. Overall, it indicated that Wales was only commissioning orthodontic activity to meet 76% of the annual orthodontic need. Overall, 97.9% of commissioned primary care orthodontic activity was being used to provide treatment for 9,500 patients per year. Furthermore, 112 GDC-registered clinicians provide NHS orthodontic care within Wales - 52 orthodontic specialists; 32 orthodontic therapists; 24 DwSIs; and 4 orthodontic trainees (StR 1-3). NHS orthodontic care is provided at 47 sites within Wales - 32 sites in the GDS/Specialist Practice, 6 sites within the CDS and 9 secondary care settings.Conclusions NHS commissioned primary care orthodontic activity within Wales is 76% of the potential orthodontic annual need. Primary care orthodontic services are efficient with 97.9% of commissioned activity being used to provide treatment. In total, 112 GDC-registered clinicians provide NHS orthodontic care across 47 sites within Wales, with 29.5% of clinicians working at multiple sites. The distribution of the orthodontic providers is predominately in areas of high population density, resulting in some rural communities being a significant distance from any orthodontic provider.

Assessment of orthodontic borderline treatment need: A comparison of two aesthetic indices

ObjectiveTo compare a new “guide for borderline orthodontic need” (GBON) with the “aesthetic component” (AC) of the IOTN in assessing borderline cases (dental health component DHC 3), and to compare reliability and opinions of orthodontists on the use of each index.Materials and methodsCross-sectional population descriptive study. Ninety-four qualified orthodontists assessed 30 borderline malocclusions according to the GBON and AC indices and completed a questionnaire.ResultsKappa analysis showed GBON and AC to have similar intra-examiner reliability (K = 0.64 and 0.60 ,respectively). Cronbach’s alpha inter-examiner reliability analysis showed GBON and AC to have similar, acceptable reliability (α = 0.7 and 0.9 ,respectively). There was only fair agreement between GBON and AC in terms of the number of malocclusions deemed as needing treatment (AC threshold 6). Analysis of specific occlusal traits revealed that reverse overjets were deemed as needing treatment according to AC but not anterior open bites. Both traits were assessed as needing treatment according GBON. Despite a lack of familiarity with GBON, assessors found GBON easier to use and more appropriate in assessing borderline malocclusions.ConclusionsBoth GBON and AC had good and similar inter- and intra-examiner reliability. There was substantial agreement on treatment need between GBON and AC but only when the AC threshold is reduced to 4. GBON was more able to identify malocclusal traits in need of treatment than AC. GBON was found to be easier to use and considered more appropriate than AC in judging DHC 3 malocclusions.

The development of a guide to borderline orthodontic need

ObjectiveTo produce a guide for dentists and orthodontists to determine orthodontic treatment need in borderline cases (dental health component DHC 3) and to compare views of different panels of judges on treatment need.Materials and methodsProspective, observational study. Photographs of one hundred subjects displaying borderline occlusal traits (DHC3) were collected. Three panels of judges consisting of 25 orthodontists, 25 dentists and 25 lay persons assessed photographs based on orthodontic treatment need on aesthetic grounds.ResultsSpearman’s correlation coefficient showed no statistical difference between the panels of judges (p < 0.001). The judges identified a ‘high need’ for treatment on aesthetic grounds for those with anterior open bites and reverse overjets. Kappa analysis showed moderate intra-rater agreement for the orthodontic and dental panels of judges (k = 0.47 and 0.45, respectively) and fair agreement (k = 0.26) for the lay panel, highlighting the intrinsic difficulty of assessing borderline malocclusions.ConclusionThere was no statistical difference in the way the orthodontic, dental and lay panels of judges perceived treatment need for DHC 3 cases. Anterior open bites and reverse overjets were predominantly found to be in high need of treatment by all panels of judges. A ‘Guide to Borderline Orthodontic Need’ (GBON) is proposed consisting of 8 photographs of subjects with borderline occlusal traits (DHC3) determined unambiguously by lay, dental and orthodontic panels as either ‘needing’ or ‘not needing’ orthodontic treatment on aesthetic grounds. It is anticipated that this will assist users to make judgments on aesthetic grounds on the need for treatment in borderline cases.

The effects of corticotomy and piezocision in orthodontic canine retraction: a randomized controlled clinical trial

BackgroundThe aims of this study were to evaluate the efficacy of alveolar corticotomy (AC) and piezocision (PZ) in accelerating maxillary canine retraction, and their effects on multiple bone remodeling expression in gingival crevicular fluid (GCF). A split-mouth, randomized controlled clinical trial was performed at the Department of Orthodontics of Pontifical Catholic University of Minas Gerais, Brazil. Eligibility criteria included orthodontic need for first maxillary premolars extractions, followed by canine retraction. Fifty-one adult patients were recruited and randomly assigned to 3 groups (allocation ratio 1:1:1). Random allocation of surgical or control interventions to each side of the maxillary arch was also conducted: G1 − AC × Control, G2 − PZ × Control, and G3 − AC × PZ. Both the definition of the group and the decision of the experimental or control sides were randomized by the software. Intraoral digital scans were performed before, 7 and 14 days after the beginning of canine retraction, and subsequently, at every 14 days until a maximum period of 6 months. GCF samples were collected before, and 1, 2, 4, 8, and 12 weeks. The primary outcome consisted in the cumulative distal movement of the canines and was measured by digital model superimposition. The secondary outcome consisted in GCF bone remodeling samples that were quantified in a multiplex immunoassay. The measurements examinator was properly blinded.ResultsForty-seven patients, 19 males and 28 females, were analyzed (mean age 20.72, SD = 6.66, range 15 to 38). Statistically significant differences in canine distal movement between AC and control in G1 were not observed (p > 0.05). In G2, PZ showed lower cumulative incisal and cervical measurements than control from the 2nd to the 24th week (p < 0.05). In G3, PZ showed a lower cumulative incisal and cervical measurements than AC from the16th to the 24th week (p < 0.05). In all groups, differences on biomarkers expression occurred at specific timepoints (p < 0.05), but a distinct pattern was not observed.ConclusionsAC and PZ were not effective to accelerate maxillary canine retraction and did not induce a distinct pattern of biomarker expression.Trial registrationNCT03089996.

Orthodontic Treatment Need at Nishter Institute of Dentistry

Background: The Index of Orthodontic Treatment Need (IOTN) is one of the important index to find out orthodontic need of patients. Aim: To find out the need of orthodontic treatment in patients visiting Nishter Institute of Dentistry, Multan (NID). Method: The index was applied using plaster models and intraoral examination. The measurements of various components of IOTN index was taken with the help of digital vernier calliper. Results: The results of various measurements of IOTN index was taken, recorded and analyzed statistically. Result of the present cross-sectional study showed that 65% patients were in grade 4 and 5 of IOTN. The analysis showed that 13% were in grade 4 of IOTN, 52% were in grade 5, 15% were in grade 3, 16% were in grade 2 and 4% patients was in grade 1 of IOTN index. Conclusion: No significant sex differences were shown for the need of orthodontic therapy in any category of IOTN. The need of orthodontic treatment is very high in patients of Southern Punjab, Pakistan. Keywords: Treatment Need; IOTN; Orthodontics.

What are the factors influencing the aesthetic requirement in the choice of orthodontic appliances in adults?

Although adult patients are said to be demanding in terms of discretion of the orthodontic appliance, the factors influencing the choice of the appliance are still poorly understood. The main objective of this study was to determine if there is a correlation, in adults, between the importance of the orthodontic treatment need and the aesthetic preference of the orthodontic appliance (metal braces, ceramic braces in buccal, lingual or aligner). The secondary objectives were to evaluate the impact of the patient's personal factors, his eventual orthodontic past and his perceived orthodontic need. Patients were interviewed by questionnaire before the first consultation. An index, depending of the discretion of the appliance, was used. The need for treatment was calculated via dental health component and aesthetic component of IOTN. Given the size of the sample, only trends can be emitted. The real need for treatment had no influence on the choice of the aesthetic appliance. The most demanding patients would be women, in their thirties, single, employed, executive or practicing a higher profession, with previous orthodontic treatment and having recently consulted an orthodontist, as an adult. These patients felt that their orthodontic treatment need was minimal or significant. Patients estimated the duration of treatment at 17 months. Lingual was considered the most aesthetic appliance far ahead of the aligners. A larger scale study is needed to determine the influence of each factor.

Can orthodontic need cause bullying?

ABSTRACT Objective: To determine the association between orthodontic treatment need and the self-reported bullying, and its impact on adolescents’ self-esteem. Methods: The sample consisted of 160 schoolchildren from 11 to 14 years of age, enrolled in public schools. The history of bullying was evaluated by means of the Crozier; Dimmock adapted Questionnaire (1999). Self-esteem was determined by means of the Global Negative Self-Evaluation Scale (GSE). The normative orthodontic treatment need was determined by the Dental Health Component (DHC) and perceived need, by Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Individual analyses were made of the associations with the history of bullying (outcome). Results: The variables that presented P ? 0.20 in the individual analyses were tested in a multiple logistic regression model, and variables with P ? 0.05 remained in the model. The odds ratios with the intervals of confidence were estimated. According to the results 72.5% of the schoolchildren reported a history of bullying. The schoolchildren who presented negative impact on the quality of life related to oral symptoms and negative self-esteem were observed to have 4.59 and 5.44 times more chance, respectively to report a history of bullying (P &lt; 0.05), which did not suffer the influence of normative and perceived orthodontic treatment need. Conclusion: The history of bullying was not influenced by orthodontic treatment need, but by the low self-esteem of adolescents.

Early orthodontic treatment need among 6-9-year-old children of West Bengal

Background: Early orthodontic treatments (EOTs), which basically include interceptive and preventive orthodontic procedures, are relatively simple and cost-effective treatment approaches that target developing malocclusions during the mixed dentition period. The present study is aimed to assess the need for EOT among 6–9-year-old children of West Bengal that would benefit from preventive and interceptive orthodontic treatment to prevent or reduce the number of late/corrective orthodontic treatments, which can be complex, lengthy, and costly. Materials and Methods: A total of 1129 children from different public and private primary schools of West Bengal were evaluated using index for preventive and interceptive orthodontic need (IPION). On the basis of IPION, the overall scores of children were distributed into three groups – no treatment need, moderate treatment need, and definite treatment need. According to dental development, children were divided into two groups – IPION-6 and IPION-9. Results: Among 1129 children examined, 554 children (49.1%) came under the category of no treatment need, 174 children (15.4%) presented with moderate treatment need, and 401 children (35.5%) showed definite treatment need. The IPION groups had a significant effect on treatment need distribution (6 vs. 9, P = 0.010)); the IPION-9 scores were significantly higher than the IPION-6 scores. Conclusion: The prevalence of preventive and interceptive orthodontic treatment need is unsatisfactorily high in children of West Bengal, which highlights the importance of including preventive and interceptive orthodontic treatment in local dental health-care programs.

СТРУКТУРА ЗУБОЧЕЛЮСТНЫХ АНОМАЛИЙ И НУЖДАЕМОСТЬ В ОРТОДОНТИЧЕСКОМ ЛЕЧЕНИИ ЛИЦ 20-23 ЛЕТ

The frequency of dentoalveolar anomalies and the need for orthodontic treatment were studied according to the IOTN index of 79 young people of both sexes aged 20—23 years. It was found that there is no statistically significant difference in the frequency of dentoalveolar anomalies among persons of both sexes. 95 % of the surveyed have any dentoalveolar anomalies: 51,9 % — malocclusion, 75,9 % — anomalies of the dentition, 84,8 % — anomalies of the teeth; high need for orthodontic treatment according to the dental component of the IOTN index was found in 6,3 % of the surveyed, the average degree — in 43,0 %, do not need orthodontic treatment 50,6 % of surveyed; according to the aesthetic component of the IOTN index do not need orthodontic treatment or need light intervention 100 % of the surveyed children.

SELF-PERCEIVED ORTHODONTIC NEED, INFORMATIONSEEKING BEHAVIOUR AND KNOWLEDGE ON ORTHODONTIC TREATMENT AMONG YOUNG MALAYSIAN ADULTS

Objective: This study aimed to assess self-perceived aesthetics and orthodontic need, information-seeking behaviours and knowledge on orthodontic treatment among young adults in Malaysia. Methods: A cross-sectional study was conducted among 933 polytechnic students in Malaysia using a selfadministered questionnaire. The Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used to assess self-perceived orthodontic need. Respondents were also asked about their intention to seek orthodontic treatment. Those showing intention were further asked about their reason(s) for seeking treatment, their information-seeking behaviours, and knowledge on orthodontic treatment. Data was analysed using SPSS. Results: The overall response rate was 93.2% with the mean age of 20.43 (SD±1.07). Although most of the respondents rated themselves under the no treatment need category of the AC-IOTN scale, 61.9% reported intention to seek orthodontic treatment. The main reason for seeking treatment was to improve dental function (45.3%) and aesthetics (40.1%). Most claimed to look for information prior to orthodontic treatment, either using online or offline platforms. Many relied on friends (83.3%) as a source of information and more than half used online sources including social media and websites. A minority demonstrated lack of knowledge in terms of appropriate places to receive treatment (2.2%) and qualification of orthodontic practitioners (37.7%). Conclusions: The majority of young Malaysian adults have high intention to seek orthodontic treatment regardless of their perceived need. A minority had lack of knowledge about qualified orthodontic providers and places to receive treatment. Majority reported positive attitudes towards information-seeking behaviour prior to seeking orthodontic treatment.

Association of self-esteem with perceived orthodontic treatment need and oral health-related quality of life among 12-15 years schoolchildren - A cross-sectional study

Objectives: The objective of the study was to assess the association of self-esteem (SE) with perceived orthodontic treatment need and oral health-related quality of life (OHRQoL) among 12–15 years old schoolchildren in Bengaluru city, India. Materials and Methods: A cross-sectional study was conducted among 400 schoolchildren aged 12–15 years in Bengaluru city, India. The data were collected on a structured pro forma that included demographic profile, perceived orthodontic treatment need questionnaire, Child Oral Health Impact Profile (COHIP), and the modified version of the Harter’s self-perception profile rated by the children. ANOVA, Chi-square test, and multivariate linear analysis models were used. P &lt; 0.05 was considered as statistically significant. Results: The mean age of the study group was 13.21 ± 1.08 years. Most of the study participants were female (53%). Among the participants, 67% perceived orthodontic treatment need. Mean scores for COHIP and SE were 38.3 ± 10.7 and 91.5 ± 8.3, respectively. In multivariate linear regression analysis, SE was significantly associated with OHRQoL (0.161 [95% confidence interval CI 0.086–0.235)] and perceived orthodontic need [−0.701 (95% CI −1.252, −0.151)]. Conclusion: In this study, orthodontic treatment needs influenced SE and OHRQoL in the children. Hence, early diagnosis and prompt treatment can improve SE and OHRQoL.

Influence of social capital on self-perception related to orthodontic treatment need

Aim: To evaluate the influence of social capital on self-perception related to orthodontic treatment need. Methods: A cross-sectional study was conducted with a sample of 578 11-16 years-old adolescents from a city in southern Brazil. Social capital was evaluated using the Social Capital Questionnaire for Adolescent Students (SCQ-AS). Index of Orthodontic Treatment Need (IOTN) assessed malocclusion and self-perception related to orthodontic treatment need. Sociodemographic aspects of adolescents were also evaluated. Individual analyses were performed, relating the study variables to the outcome, estimating the odds ratio with the respective confidence intervals of 95%. The variables with p&lt;0.20 in the individual analyses were tested in the multiple logistic regression models, and those with p&lt;0.10 remained in the model. Results: Social capital did not influence the self-perception related to orthodontic treatment need. Adolescents with high orthodontic needs were 5.35 (CI 95%: 2.68 to 10.65) times more likely to perceived orthodontic treatment need (p &lt;0.05). Crowding and dental absence were associated with self-perception related to orthodontic treatment need (p &lt;0.05). Conclusions: Social capital did not influence the self-perception related to orthodontic treatment need.

Index of Orthodontic Treatment Need (IOTN) for Libyan Children in Benghazi: An ep- idemiological survey on school children in Benghazi city

Background: malocclusion is a common oral health problem that can affect the psychosocial well-being in thelong term. Many indices were developed to prioritize patients so that those who have the greatest need receivetreatment. Objectives: this study was aimed to assess the orthodontic treatment need of Libyan children using&#x0D; index of orthodontic treatment need (IOTN). Methods: Total of 511 students (260 females, 251 males) consti-tuted the sample, which was randomly selected from age group of 12-14 years in Benghazi public schools. The&#x0D; dental health component (DHC) of IOTN was applied to assess orthodontic need, whereas the aesthetic com-ponents (AC) of IOTN along with a questionnaire were used to evaluate participants’ perception towards their&#x0D; own orthodontic status. Results: the majority of participants (79. 5%) displayed smile satisfaction, with gen-der difference (p&lt;0. 05). Satisfaction with teeth appearance was showed by 39. 7% of the respondents while&#x0D; 60. 3% of the participants were dissatisfied, owing dissatisfaction to various reasons such as color of their teeth(9%) and teeth arrangement (34. 8%). More than half of respondents (55%) considered well arrangement ofteeth is crucial for overall facial appearance. According to ac there was a strong agreement between researcherand respondents in treatment need. The researcher found 10% were definitely needed treatment against 6. 2%found by self-perceived need; the researcher categorized 71.4% of the respondents as no treatment needagainst 71. 4% found by self-perceived need.Conclusions: most of the children in Benghazi`s public schools are satisfied with teeth appearance. Most of thepublic schools children in Benghazi need no/slight orthodontic treatment need. Age, gender and socioeconomicwere not influencing factors affecting orthodontic treatment need among Libyan children in Benghazi.

Association Between Psychosocial Status and Orthodontic Treatment Needs in Indonesian High School Students

Objective: To determine whether psychosocial status is associated with orthodontic treatment needs in high school students using the Psychosocial Impact of the Dental Aesthetic Questionnaire (PIDAQ) and the Index of Orthodontic Need (IOTN). Material and Methods: This cross-sectional study comprised 95 adolescents, both genders, aged 15–17 years old. PIDAQ was used to assess psychosocial status. The IOTN Aesthetic Component (IOTN-AC) and the IOTN Dental Health Component (DHC) was used to assess treatment needs . Examination of the oral cavity was carried out with the help of the IOTN ruler by observing the MOCDO components: missing teeth, overjet, crossbite, displacement, and overbite. The Chi-square test was used to determine the association of psychosocial status and orthodontic treatment need. The reliability test was carried out by using Cronbach’s Alpha test (0.978). Results: There was an association between psychosocial status and orthodontic treatment need based on the IOTN-AC (p=0.001) and between psychosocial status and orthodontic treatment need based on the IOTN-DHC (p=0.140) . Conclusion: There is an association between psychosocial status based on the PIDAQ and subjective orthodontic treatment need based on the IOTN-AC, but there is no association between psychosocial status based on the PIDAQ and objective orthodontic treatment need based on the IOTN-DHC in students of SMAN 27 Jakarta.

Relationship between normative and self-perceived criteria for orthodontic treatment need and satisfaction with esthetics and mastication in adolescents

Orthodontic treatments are performed to improve esthetics and masticatory functions. In general, clinical criteria are used to recommend such treatments without considering the opinion of the patient. This study aimed to evaluate the relationship between technically defined orthodontic need (normative criteria) and the need for treatment perceived by adolescent patients. A total of 215 students aged between 15 and 19years were selected and asked to respond to a questionnaire concerning their perception of need for orthodontic treatment and their satisfaction with their own esthetics and mastication. One trained and calibrated examiner obtained normative data using the Dental Aesthetic Index (DAI) on the need for orthodontic treatment of these students. Associations were found between the DAI score and the patient's perception of need for orthodontic treatment (P<0.001), satisfaction with esthetics (P=0.003), and satisfaction with mastication (P=0.047). When occlusal characteristics were analyzed separately, associations between several normative and perceived needs, as well as for satisfaction with esthetics, were found. Satisfaction with mastication analysis was only found to be associated with open bite malocclusion (P=0.003). The DAI revealed a consistent opinion in adolescents to link their perceived malocclusion-related conditions to esthetics.

To accept, or not to accept? A service evaluation to appraise complexity assessment of orthodontic patients referred into a secondary care setting.

Introduction Commissioners in England use the Commissioning for Quality and Innovation (CQUIN) payments mechanism to encourage the best provision of orthodontic treatment. However, CQUIN only use the patient's orthodontic need as a measure of complexity, rather than the levels outlined in the orthodontic commissioning guide published by NHS England. A service evaluation was designed to ascertain a secondary care setting's compliance with the commissioning complexity levels, as a new comparator for CQUIN case-mix assessment.Materials and methods A prospective evaluation was conducted for all new patients referred to the Mid Yorkshire NHS Trust orthodontic department in a 12-month period, using the levels categorised by the commissioning guide. A standard was set to accept no fewer than 80% level 3b patients.Results Of patients accepted for orthodontic treatment, 89.9% were of the highest level 3b complexity. This was compared to only 69.8% of patients having an Index of Orthodontic Treatment Need, Dental Health Component, 5.Conclusion The findings support a recommendation that commissioners should consider complexity based on the commissioning guidance, rather than orthodontic need alone; it is important that the economic drivers of commissioning implementation fairly reflect the specialist work being carried out by the workforce.
