Prevalencia de Anomalías Dentomaxilares y Necesidad de Tratamiento Ortodóncico en Escolares del Pueblo Originario Rapa Nui / Prevalence of Dentomaxillary Anomalies and Need for Orthodontic Treatment in School Children of the Rapa Nui Native People

El objetivo de este estudio fue determinar la prevalencia de anomalías dentomaxilares y la necesidad de tratamiento ortodóncico en escolares pertenecientes al pueblo originario de Rapa Nui. Se realizó un estudio descriptivo, observacional, transversal y no probabilístico. Se evaluaron 85 alumnos entre primero básico y primero medio, entre los 6 y 16 años de edad, de dos colegios de Rapa Nui. Se realizó un examen clínico estandarizado, realizado por dos investigadores previamente calibrados, donde se completó una ficha clínica diseñada para el estudio. Para el análisis de las anomalías dentomaxilares se realizó un escaneo digital de la cavidad oral completa para su posterior análisis. De 85 estudiantes evaluados, 75 (88,2 %) se encontraban afectados por algún tipo de anomalía dentomaxilar en el plano sagital, vertical y/o transversal, independiente de su gravedad. Un 87,1 % de los estudiantes necesitan tratamiento ortodóncico según el Índice de Necesidad de Tratamiento Ortodóncico, de los cuales un 57,7, % se clasificó dentro de los rangos de moderado, grave y muy grave. Existe una alta prevalencia de anomalías dentomaxilares en los escolares pertenecientes al pueblo originario Rapa Nui, encontrándose por sobre las cifras nacionales como internacionales, lo cual da como resultado que la mayoría de los alumnos evaluados necesiten de algún tipo tratamiento ortodóncico, ya sea preventivo, interceptivo y/o correctivo.

The aim of this study was to determine the prevalence of dentomaxillary anomalies and the need for orthodontic treatment in schoolchildren belonging to the Rapa Nui native people. A descriptive, observational, cross- sectional and non-probabilistic study was carried out. Eighty- five students between first grade and first middle school, between 6 and 16 years of age, from two schools of Rapa Nui were evaluated. A standardized clinical examination was performed by two previously calibrated investigators, where a clinical record designed for the study was completed. For the analysis of dentomaxillary anomalies, a digital scan of the full mouth was performed for subsequent analysis. Of 85 students evaluated, 75 (88.2 %) were affected by some type of dentomaxillary anomaly in the sagittal, vertical and/or transversal plane, regardless of its severity. Some 87.1 % of the students needed orthodontic treatment according to the Orthodontic Treatment Need Index, of which 57.7 % were classified within the moderate, severe and very severe ranges. There is a high prevalence of dentomaxillary anomalies in schoolchildren belonging to the Rapa Nui native people, which is above the national and international figures, resulting in the majority of the students evaluated needing some type of orthodontic treatment, whether preventive, interceptive and/or corrective.

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

Abstract 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.

Introduction: dental malocclusions are dentomaxilofacial anomalies which are found very frequently in the world population. There is registered information about the application of epidemiological indexes to identify the orthodontic treatment needs. Objective: to identify the scientific production where the indexes of orthodontic treatment needs are applied. Methods: a cross-sectional and descriptive study was carried out from January to December 2013. The required information was found in Medline, PubMed and Regional Scielo databases. The data were taken in the following periods: 1975-1993, 1994-2003 and 2004-2013. The universe of study consisted of 439 abstracts and/or articles from which 334 were selected for the sample after meeting the inclusion criteria. Results: in the 1975-1993 period, 24 articles (7.2 percent) were identified, 98 articles (29.3 percent) in the 1994-2003 period and 212 (63.5 percent) from 2004 to 2013. The papers comprising just one index amounted to 273 (81.73 percent), two indexes combined in 49 (14.7 percent) and 3 or more in 12 (3.6 percent). Conclusions: in the first analyzed period, the most used indexes were priority orthodontic treatment index; dental esthetic index, index of orthodontic treatment need. During the second and third periods, the index of orthodontic treatment need prevailed with increased individual application of its esthetic component and the dental clinical component too. In general, this index was the most used alone or in combination, followed by the dental esthetic index(AU)

Functional needs of subjects with dentofacial deformities: A study using the index of orthognathic functional treatment need (IOFTN).

OBJECTIVES: To assess the functional needs of orthognathic patients treated in Isfahan University of Medical Sciences affiliated hospitals using the index of orthognathic functional treatment need (IOFTN). MATERIALS AND METHODS: A retrospective study was conducted using 2011-2015 records of 103 patients [58 female, 45 males, 16-45 years, mean (SD) age = 23.47 (6.44) years] who had orthognathic surgery. Malocclusion type (incisor classification), sagittal skeletal pattern (ANB angle), IOFTN score, and Dental Health Component of the IOTN [IOTN (DHC)] were recorded. RESULT: Overall, 92.2% and 82.5% of subjects scored 4 or 5 for IOFTN and IOTN (DHC), respectively, and no gender differences detected for both indices (P > 0.05). Gender differences detected for malocclusions/skeletal patterns (P < 0.05). Class III malocclusions (45.6%) and Class II skeletal patterns (51.5%) were the most prevalent type. Subjects with Class I, Class II, and Class III sagittal skeletal bases formed 4.8%, 51.5%, and 43.7% of the sample, respectively. IOFTN score of 5.3 (reverse OJ ≥ 3 mm, 27.2%) was the most prevalent, followed by 4.2(19.4%), 4.3(13.6%), 4.10 (12.6%), and 5.2 (8.7%). Subjects with Class III sagittal skeletal patterns or malocclusions had higher percentages of grade 5 IOFTN scores (62.2% and 59.6%), compared to Class II sagittal skeletal patterns or malocclusions (18.9% and 21.2%) and the distribution of functional needs between malocclusions or sagittal skeletal patterns were different (p < 0.01). CONCLUSION: IOFTN identified 92.2% of orthognathic surgery patients as having great and very great functional needs and appeared to be reliable tool to identify patients in need of orthognathic surgery. Higher percentages of Class III subjects scored grade 5 of IOFTN, indicating higher functional need for orthognathic surgery in this group.

Self-perceived need for dental treatment and related factors. A cross-sectional population-based study

Abstract This study compared adolescents' self-perceived need for orthodontic treatment with the normative need for such treatment and investigated associations between socioeconomic and demographic variables and self-perceptions of dental malocclusion. This cross-sectional study involved 1015 schoolchildren aged 12-15 years in São Luís, Maranhão, Brazil. The following data were collected using a questionnaire and an orthodontic examination card: demographic and identifying data, socioeconomic data, educational levels of family, household income, economic classification criteria, and self-reported skin color behavioral data, and oral health data. Normative occlusal condition was examined using the Angle classification and Dental Aesthetic Index (DAI). Data were analyzed using the chi-squared test (to analyze differences in the frequency distribuition of qualitative variables) and Poisson regression (to stimate associations between the perceived need of orthodontic treatment and study covariates), with a 5% significance level. Schoolchildren's self-perceived need for orthodontic treatment was associated with sex (p = 0.022) and the normative need for treatment (p = 0.004). Among socioeconomic, demographic, and oral health variables, only sex [prevalence ratio (PR) = 1.15; 95% confidence interval (95%CI) = 1.04-1.28; p = 0.009] and the normative need for orthodontic treatment (PR = 1.19; 95%CI = 1.08-1.32; p < 0.001) were associated with the perception of malocclusion, with female adolescents reporting a greater need for orthodontic treatment. Female adolescents seems to be more sensitive to oral health problems. The results suggest that the DAI score might reflect a self-perceived need for orthodontic treatment and the Angle classification might overestimate the orthodontic treatment need.
