RESUMO

SUMMARY: Orthodontically induced inflammatory root resorption (OIIRR) is a complication of dental treatment which consists of the degradation of local tissue due to an inflammatory reaction provoked by inappropriate orthodontic stimulus. The aim of the present systematic review was to assess the effectiveness of low-level laser therapy (LLLT) in reducing orthodontically induced inflammatory root resorption (OIIRR) in animal models. A systematic review was carried out in the MEDLINE, EMBASE and LILACS databases. Studies of interventions in animals were selected which analysed the effect of LLLT on OIIRR repair. The risk of bias was analysed through the 10 domains of the SYRCLE RoB tool for animal studies. Seventy-one studies were found; 27 were eliminated as duplicates and 44 titles/abstracts were analysed. Of these, 38 were excluded, and five studies were included for qualitative analysis. In 66.6 % of the studies included, the authors state that LLLT was effective in the inhibition/repair of OIIRR. In histological analysis it was observed that root resorption was significantly less in animals treated with laser as compared to the control. Furthermore, LLLT accelerated cicatrization after OIIRR. Laser proved effective in reducing root resorption lacunae and shortening the inflammatory process induced by the application of orthodontic force.


RESUMEN: La resorción radicular inflamatoria inducida por tratamiento ortodontico (RRIITO) es una complicación del tratamiento odontológico que consiste en la degradación del tejido local debido a una reacción inflamación provocada por un estímulo ortodóntico inadecuado. El objetivo fue analizar la efectividad de la terapia láser de baja intensidad (LBI) en la disminución de RRIITO en ratas. Se realizó una revisión sistemática en las bases MEDLINE, EMBASE y LILACS. Fueron utilizados los términos 'resorción radicular', 'láser de baja intensidad', 'fototerapia', 'tratamiento ortodóntico', 'movimiento dental'. Fueron seleccionados estudios de intervención en animales, que analizaron el efecto del LBI en la reparación de la RRIITO. Los riesgos de sesgos fueron analizados mediante los 10 domínios de la herramienta SYRCLE RoB para estudios en animales. 71 estudios fueron encontrados, siendo eliminados 27 duplicados, y analizados 44 títulos/abstracts; de estos, fueron incluídos 5 estudios para análisis cualitativa. El 66,6 % de los estudios incluidos afirman que el LBI fue efectivo em reparar la RRIITO. En el análisis histológico se observó que la RRIITO fue significativamente menor en animales tratados con láser en comparación con el control. Además de eso, el LBI aceleró el proceso de cicatrización de la RRIITO. El láser se mostró efectivo en reducir las lagunas de resorción radicular y acortar el proceso inflamatorio inducido por la aplicación de fuerzas ortodonticas.

RESUMO

RESUMEN: La determinación de la discrepancia de la longitud del arco y del tamaño del diente en la dentición mixta, requiere una predicción precisa del ancho mesiodistal de los dientes permanentes no erupcionados, para prevenir futuras maloclusiones. Objetivo: fue generar una nueva ecuación regresiva para predecir el diámetro mesiodistal de premolares y caninos, usando como predictor incisivos inferiores y molares superiores. Material y método: El estudio se realizó en el Centro Clínico de la Araucanía. La muestra está compuesta por modelos dentales históricos de 200 escolares (93 niños y 107 niñas) de toda la IX región, Chile. Edad de 13-16 años. Las mediciones del ancho mesiodistal de incisivos mandibulares, caninos y premolares maxilares y mandibulares, se realizaron con la ayuda del calibrador Vernier calibrado a 0,01 de un milímetro. Resultados: Estos muestran que hay una correlación moderada entre el molar superior y premolares superiores e inferiores. Además, los incisivos inferiores se correlacionan en mayor medida con los caninos superiores e inferiores. No hay diferencias significativas entre hombres y mujeres. Conclusión: Se desarrolló una nueva fórmula con un 75% de precisión para predecir el ancho de dientes caninos y premolares en dentición mixta en la población chilena de la región de la Araucanía, siendo mejor que la actual fórmula de Tanaka.


ABSTRACT: Precautionary measures are necessary to prevent a potential irregularity from progressing into a more severe malocclusion. The determination of the tooth size-arch length discrepancy in mixed dentition requires an accurate prediction of the mesiodistal widths of the unerupted permanent teeth to prevent future malocclusions. Objective: The purpose of this study is to generate a new regressive equation to predict the diameter of the cuspid and bicuspid by measuring the wide of lower incisor and upper molar teeth in a Chilean population sample. Matherials and methods: the study was conducted in the Araucanía Clinical Center in Temuco city and the sample was composed of historical dental cast from 200 school children (93 boys and 107 girls), of IX region, Chile. Age group of 13-16 years old. Measurements of the mesiodistal widths of mandibular incisors, maxillary and mandibular canines and premolars were made with the help of Vernier gauge calipers calibrated to 0.01 of 1 millimeter. Results: The results show that there is a moderate correlation between the upper molar and upper and lower premolars. In addition, the lower incisors are correlated to a greater extent with the upper and lower canines. There are no significant differences between men and women. Conclusion: A new formula with 75% accuracy was developed to predict the width of canine teeth and premolars in mixed dentition in the Chilean population of the Araucanía region. This formula is better than the current Tanaka method.

RESUMO

Abstract Introduction: Long-term home oxygen therapy (LTOT) can be successfully used in the treatment and prevention of chronic lung diseases, as it improves quality of life, increases survival, and reduces the lenght of hospital stays. However, to the authors' knowledge there are no descriptive studies with details of the clinical and social profile of patients using LTOT in the state of Paraná. Objective: To analyze the profile of LTOT users in the state of Paraná. Method: All patients registered in the LTOT program of the Curitiba Municipal Department of Health were recruited to the study. Participants answered a questionnaire with questions about their education level, family income, main diagnosis, comorbidities, hours/day of O2 use, and hospitalizations in the previous year. Results: 386 patients (67 ± 20.4 years; 66% females) were interviewed. Chronic obstructive pulmonary disease (COPD) was the most common disease (58.5%); 60.6% were former smokers and 84.5% did not practice any kind of physical activity; dyspnea was the most common symptom (81.3%) and immobility was the most commonly reported inconvenience (33%); 55.7% used O2 24 hours a day; 53.6% had been hospitalized in the previous year; 33.9% had not completed primary school; 31.4% had an income of one minimum monthly wage or less. Conclusion: LTOT users in Curitiba are primarily elderly women with COPD, with low family income and limited schooling. It is extremely important that health professionals provide educational and preventive measures for this population, to minimize the impact of COPD in the community.

RESUMO

SUMMARY: The principal orthodontic problems observed in the mixed dentition phase are related to arch length and tooth size discrepancy. In order to identify such space discrepancies different methods of mixed dentition space analyses have been introduced. For this reason the purpose of this study is to generate a new regressive equation to predict the diameter of cuspid and bicuspid teeth through mesiodistal widths of lower incisors in a Chilean population sample between native and non-native population. The study was conducted at the Araucania Dental Clinic in Temuco, and the sample comprised of historical dental casts from 200 school children (93 boys and 107 girls) from Temuco, Chile, between 13-16 years of age. The native Mapuche population consisted of 107 students and the non-native of 93 students. Measurements of the mesiodistal widths of mandibular incisors, maxillary and mandibular canines and premolars were carried out with the help of Vernier gauge calipers calibrated to 0.01 of a millimeter. The results show that there are differences in the mesiodistal diameter size of incisors, and canines and premolars in the two studied groups. There is a low correlation of the variables studied. In conclusion, significant sexual dimorphism in tooth sizes exists in the native sample, and there is no difference in non-native population. It is necessary to develop a predictive formula that is greater than 70 % of accuracy for clinical application. Resonance imaging (MRI).


RESUMEN: El principal problema ortodóncico observado en la etapa de dentición mixta está relacionado con la longitud del arco y la discrepancia del tamaño de los dientes. En orden a identificar tal discrepancia de espacio, diferentes métodos de análisis de espacio en dentición mixta han sido introducidos. Por esta razón el objetivo de este estudio fue generar una nueva ecuación regresiva para predecir el diámetro mesiodistal de caninos y premolares a partir del ancho de los incisivos centrales inferiores en una muestra de población chilena nativa y no nativa. El estudio fue realizado en la Clínica de Ortodoncia Araucanía en Temuco. La muestra fue seleccionada de una colección histórica de modelos dentales, 200 escolares (93 niños y 107 niñas) de la ciudad de Temuco, Chile con edades entre 13 y16 años. La población nativa fueron 107 estudiantes Mapuches y los no nativos fueron 93 estudiantes. Las mediciones del ancho mesiodistal de los incisivos mandibulares, caninos maxilares and mandibulares y premolares fueron realizadas con la ayuda de un medidor Vernier calibrado a 0.01 de milímetro. Los resultados muestran que hay diferencias en el diámetro mesiodistal de incisivos, y caninos y premolares en los grupos estudiados. Hay una baja correlación de las variables estudiadas. En conclusión, hay diferencias significativas en el tamaño de dientes entre hombres y mujeres en la muestra de nativos, y no hay diferencias en la población no nativa. Es necesario desarrollar una fórmula predictiva que sea mayor a 70 % de seguridad para aplicaciones clínicas.

RESUMO

OBJECTIVES: To assess the effectiveness of low-level laser therapy (LLLT) in reducing orthodontic pain after the application of orthodontic force (OF). METHODS: A systematic search was conducted in the MEDLINE, EMBASE, Scopus, Cochrane Library, Web of Science, and EBSCOhost databases. The study included randomized clinical trials (RCT) which analysed the effectiveness of LLLT in reducing orthodontic pain assessed at 24 and 72 hrs after the application of OF. The risk of bias of the eligible trials was assessed using the Cochrane Collaboration's risk of bias tool. Standard mean difference was calculated and pooled by meta-analysis using random effect models. RESULTS: Of 467 identified articles, 20 RCT were finally included. In the risk of bias assessments, 13 studies presented a high risk, 5 an unclear risk, and 2 a low risk. The meta-analysis showed that in patients treated with laser versus placebo there was a difference in favour of LLLT in spontaneous pain 24 and 72 hrs after the installation of light archwires and spontaneous pain and chewing pain 24 and 72 hrs after the installation of elastomeric separators. CONCLUSIONS: LLLT proved to be effective in promoting a reduction in spontaneous and chewing pain after the application of OF; however, the poor quality of the evidence requires these results to be treated with caution.

RESUMO

ABSTRACT: Purpose: To provide an overview of different indications suitable for treatment with the technique of resin infiltration (Icon, DMG), such as white-spot lesions (WSL), enamel fluorosis, and molar-incisor hypomineralisation (MIH), and to propose a valid and strategy feasible in dental surgeries for screening of dental color improvement and -stability. Method: A non-systematic review of the literature was performed to characterise inhibition of lesion progression, and the esthetic effects induced by resin infiltration of decalcified enamel, enamel fluorosis, and molar-incisor hypomineralisation (MIH), using the online database Pubmed and a suitable search strategy. Database search was complemented by a hand-search of references of retrieved articles. Results: Of 34 retrieved articles, 29 were included in the review. Evidence of an assimilation of WSL color to surrounding enamel following infiltration is available on the level of RCTs, and the results were found to be stable in color with no significant changes over at least twelve months. Evidence of an esthetic improvement of fluorotic or MIH affected teeth is available on the level of case reports and case control studies. Conclusion: As a micro-invasive approach to infiltrate and seal different types of enamel lesions, with a subsequent improvement of the esthetic appearance, resin infiltration is considered to be a useful complementation of the dental therapeutic specter.

RESUMO

RESUMEN: La no erupción de segundos molares es relativamente baja, pero ha ido en aumento en los últimos años. Se relaciona con un tratamiento multidisciplinario largo, costoso y complejo, por lo cual es de suma importancia enfocarse en el diagnóstico precoz y tratamiento temprano. El objetivo de este estudio es poder hacer una comparación de medidas radiográficas entre un grupo de pacientes con segundo molar mandibular permanente no erupcionado o sin posibilidades de erupcionar y un grupo control. Método: Se realizó una revisión manual consecutiva de las 16.835 fichas sobre las cuales se aplicaron criterios de inclusión y exclusión. Los datos se obtuvieron de radiografías panorámicas de las cuales se obtuvieron medidas lineales y angulares que fueron comparados entre dos grupos de estudio. Se desarrolló un modelo predictivo mediante análisis discriminante. Resultados: El 1,5% de los pacientes tuvieron segundos molares no erupcionados. Los promedios de las variables relevantes fueron: Ángulo del segundo molar 33,7°; distancia desde distal del primer molar al borde anterior de la rama mandibular 15mm; invasión distal del primer molar por el segundo molar 2,1mm; inclinación mesial de segundo molar con respecto al plano oclusal 128° y al plano mandibular 63°. El puntaje crítico discriminante fue de 36,7. Conclusión: La presencia de segundos molares incluidos es baja. Se encontró diferencias estadísticamente significativas entre casos y controles en todas las variables. El modelo predictivo puede identificar molares sin probabilidad de erupción natural. Es necesario contar con nuevos estudios con muestras poblacionales para establecer cuáles serían los valores de normalidad para poder diagnosticar en forma precoz esta condición.


ABSTRACT: No eruption of seconds is relatively low, has been increasing in recent years. It relates to long, costly and complex multidisciplinary treatment, so it is important to focus on early diagnosis and early treatment. The aim of this study is to make a comparison of radiographic measurements among a group of patients with mandibular second permanent molar eruption and no possibility of a control group. Method: A consecutive manual review of 16,835 sheets on which inclusion and exclusion criteria were applied. The data were obtained from panoramic radiographs of which linear and angular measurements were compared between two study groups were obtained. A predictive model was developed using discriminant analysis. Results: 1.5% of patients had unerupted second molars. The averages of the relevant variables were: Angle of the second molar 33.7 °; distance from distal of the first molar to the anterior border of the ramus 15 mm; invasion distal of the first molar the second molar 2.1mm; second molar mesial inclination relative to the occlusal plane 128 ° and 63 ° mandibular plane. The critical discriminant score was 36.7. Conclusion: Statistically significant differences between cases and controls was found in all variables. The predictive model can identify likely molars with or without natural eruption. It is necessary to have further studies with population samples to establish what would be the normal values to diagnose this condition at an early stage.

RESUMO

To treat initial caries lesions using the technique of resin infiltration for a restoration of natural enamel appearance. Case report of a 19 year old female who presented with moderate post-orthodontic white-spot lesions (WSLs) at the upper central and lateral incisors following two years of active treatment with a fixed orthodontic appliance, and requested an aesthetic improvement of decalcified enamel surfaces. The technique of resin infiltration (Icon®, DMG, Hamburg, Germany) is presented as a means for not only inhibiting lesion progression, but also for an adequate rehabilitation of dentofacial esthetics. Practical tips and cues for clinical handling of the infiltration technique are provided. Resin infiltration augments the therapeutic spectrum for orthodontist as well as pediatric or general dentists in that enamel areas affected by post-orthodontic WSLs can be restored to their original appearance.


El objetivo fue mostrar el tratamiento de lesiones de caries iniciales usando la técnica de infiltración de resina para una restauración de la apariencia natural del esmalte. Reporte de caso de una joven de 19 años de edad, de sexo femenino que presentó lesiones moderadas de manchas blancas (WSLs) en los incisivos centrales y laterales superiores, luego del tratamiento de ortodoncia con aparatos fijos por dos años, y solicitó una mejoría estética de las superficies descalcificadas del esmalte. La técnica de infiltración de resina (Icon®, DMG, Hamburgo, Alemania) se presenta como un medio efectivo, no sólo para inhibir la progresión de la lesión, sino también para una rehabilitación adecuada de la estética dentofacial. Se proporcionan además consejos prácticos y claves para el manejo clínico de la técnica de infiltración. La infiltración de resina aumenta el espectro terapéutico del ortodoncista, así como de odontopediatras y odontólogos generales en las áreas del esmalte afectadas con WSLs post-ortodoncia y que pueden ser restauradas a su apariencia original.

RESUMO

OBJECTIVE: To test the null hypothesis of no significant difference in terms of intraoral pressure curve characteristics assessed simultaneously at the subpalatal space (SPS) and the vestibular space (VS), during different oral postures, between four groups with either an Angle Class II/1 (II1), Angle Class II/2 (II2), anterior open bite (O) malocclusion, or a neutral occlusion control group (I). MATERIALS AND METHODS: Intraoral pressure recordings were performed simultaneously in the VS and SPS of 69 consecutive subjects (nII1  =  15; nII2  =  17; nO  =  17; nI  =  20; mean age/standard deviation 18.43/6.60 years). Assessments included defined sections of open mouth posture (OMP, 30 seconds), anteriorly closed mouth condition (60 seconds), dynamics by a tongue-repositioning maneuver (TRM, 60 seconds), swallowing, and positive pressure generation (PP, 10 seconds). Interactions of malocclusion, compartment location, and posture on pressure curve characteristics were analyzed by Kruskal-Wallis and Mann-Whitney U-tests, adopting an α level of 5%. RESULTS: Globally significant group differences were detected at the VS (plateau duration and median peak heights during TRM; area under pressure curve [AUC] during PP) and SPS (AUC during TRM and PP). Subjects with anteriorly nonopen dental configurations (groups I and II2) were able to keep negative pressure levels at the VS for longer time periods during TRM, compared to groups O and II1. CONCLUSIONS: The null hypothesis was rejected for mean VS plateau durations and peak heights and for SPS AUC. Negative pressures at the VS may stabilize outer soft tissues passively and may explain the dental arch form shaping effect by mimic muscles.

RESUMO

OBJECTIVE: To test the null hypothesis of no significant difference between intraoral pressure characteristics in infants with cleft lip and palate (CLP) with or without presurgical orthopedic (PSO) plates (groups CLP and CLP-PSO), compared with noncleft infants. MATERIALS AND METHODS: Intraoral atmospheric pressure assessments were performed on 17 subjects with preoperative CLP (m/f, 11/6; mean/SD, 4.76/0.92 months) and a matched control group (n = 24; m/f, 15/9; mean/SD, 4.88/0.9 months), for 200 seconds, simultaneously at the vestibulum (vestibular space [VS]) and at the palate (subpalatal space [SPS]), using a prepared pacifier connected to a digital manometer. Areas under the pressure curves (AUC), frequencies, durations, and magnitudes of swallowing peaks and pressure resting plateaus were compared between trial groups and locations (VS, SPS) using a two-factor analysis of variance for repeated measures, Kruskal-Wallis test, and Mann-Whitney U-test (α = .05). RESULTS: The null hypothesis was rejected: Globally, there were statistically significant differences in intraoral pressure characteristics between groups CLP, CLP-PSO, and control (all P < .01), with significantly higher negative pressures (AUC) in the control subjects compared with those of CLP or CLP-PSO. There were significant effects by the location of pressure recordings (VS, SPS) and their interaction with all treatment groups. Differences between noncleft and CLP subjects were more pronounced in the VS than in the SPS. There was no significant effect by PSO. CONCLUSION: PSO does not improve deviated swallowing characteristics during suction in CLP infants.

RESUMO

BACKGROUND: Sealant application during fixed appliances orthodontic treatment for enamel protection is common, however, reliable data on its durability in vivo are rare. OBJECTIVE: This study aims at assessing the durability of a sealant (OpalSeal, Ultradent) for protection against white-spot lesion formation in orthodontic patients over 26 weeks in vivo, taking into account the provision or absence of an adequate oral hygiene. We tested the null hypothesis of (1) no significant abatement of the sealant after 26 weeks in fixed orthodontic treatment compared to baseline, and (2) no significant influence of the factor of brushing and oral hygiene (as screened by approximal plaque index, API) on the abatement of the sealant. METHODS: Integrity and abatement of OpalSeal applicated directly following bracketing was assessed in thirty-six consecutive patients (n(teeth) = 796) undergoing orthodontic treatment with fixed appliances (male/female 12/24; mean age/SD 14.4/1.33 Y). Assessment of the fluorescing sealant preservation was by a black-light lamp, using a classification that was concepted in analogy to the ARI index: (3, sealant completely preserved; 2= > 50% preserved; 1 = <50%; 0 = no sealant observable) immediately following application (Baseline, T0), after 2 (T1), 8 (T2), 14 (T3), 20 (T4) and 26 weeks (T5). API was assessed at T0 and T1. Statistical analysis was by non-parametric repeated measures ANOVA (α = 5%, power >80%). RESULTS: At baseline, 43.4% of teeth had a positive API. Oral hygiene deteriorated after bracketing (T1, 53%) significantly. Null hypothesis (1) was rejected, while (2) was accepted: Mean values of both the well brushed and non-brushed anterior teeth undercut the score "1" at T3 (week 14). Despite a slightly better preservation of the sealer before and after T3 in not-sufficiently brushed (API-positive) teeth, this finding was statistically not significant. CONCLUSION: One single application of OpalSeal is unlikely to last throughout the entire fixed appliance treatment stage. On average, re-application of the sealant can be expected to be necessary after 3.5 months (week 14) in treatment.

RESUMO

OBJECTIVE: To evaluate the validity and reliability of the T-Scan®III sensors system by measuring force and time in sensels. METHODS: In order to evaluate the validity, known forces were applied to 31 sensels selected at random of a T-Scan® III sensor. In order to evaluate the reliability, the existing agreement between two different sensors was measured. Both validity and reliability were assessed using Lin's concordance correlation coefficient (CCC). RESULTS: Using the McBride's scale, for the total group of sensels, by measuring force, a poor level of validity was obtained (Lin's CCC:0.698); when measuring time, an almost perfect agreement was obtained (Lin's CCC: 0.9995). In contrast, the reliability level was poor (Lin's CCC: 0.099). DISCUSSION: The T-Scan®III system neither shows an appropriate degree of validity when estimating absolute force, nor presents an adequate level of reliability when measuring relative force; however, it presents a high degree of validity when quantifying times.

RESUMO

La osteocondromatosis múltiple es una patología de baja prevalencia, caracterizada por la presencia de lesiones benignas formadas por cartílago hialino maduro ôosteocondromasõ, los que se desarrollan en la metáfisis de los huesos, próximos a las placas de crecimiento. Los problemas clínicos causados por los osteocondromas incluyen malformaciones esqueléticas, acortamiento asimétrico de las extremidades, y el riesgo potencial de transformación maligna a condrosarcoma. Reportamos el caso clínico de un paciente de 17 años de edad, diagnosticado con ésta patología a los 3,5 años de edad. Actualmente, con compromiso de la mayoría de sus articulaciones. El paciente fue derivado a la especialidad de ortodoncia para el manejo de su maloclusión dentaria. El tratamiento ideal por su maloclusion Clase III esqueletal, era ortodóncico-quirúrgico, el cual no se pudo hacer. Se realizó un tratamiento ortodóncico compensatorio que consistió en alinear los dientes realizando extracciones sin modificar sus maxilares, en espera de una cirugía ortognática al término del crecimiento...


Multiple osteochondromatosis is a disease of low prevalence, characterized by the presence of benign lesions consist mature hyaline cartilage ôOsteochondromas ô which develop in the metaphysis of bones near growth plates. Clinical problems caused by osteochondromas include skeletal malformations, asymmetric limb shortening, and the potential for malignant transformation to chondrosarcoma risk. We report a case of a patient of 17 years old, diagnosed with this disease at 3.5 years. Currently, with involvement of most of its joints. The patient was referred to the specialty of orthodontics for managing your dental malocclusion. The ideal treatment for its Class III jaw was orthodontic-surgical, which could not be done. Compensatory orthodontic treatment consisting performing teeth extractions align without changing their jaws awaiting orthognathic surgery at the end of growth was performed...

RESUMO

El objetivo fue determinar el beneficio de implementar acciones clínicas de ortodoncia interceptiva en paciente infantiles analizando la literatura reciente. Se realizó una revisión sistemática de la literatura mediante una búsqueda en Pubmed, SciELO y Cochrane Library de los últimos 10 años respondiendo a la pregunta: "¿En niños con maloclusiones dentoalveolares es beneficiosa la implementación de ortodoncia interceptiva o es mejor una terapia al término del crecimiento?". Las palabras de búsqueda fueron "orthodontic interceptive", "serial extraction" o sus traducciones en español. Se utilizaron criterios de inclusión y exclusión para obtener evidencia del más alto nivel. Se seleccionaron 17 artículos de los cuales, cinco fueron ensayos clínicos, seis de cohorte retrospectiva, cuatro revisiones sistemáticas y un caso clínico de larga data. La mayoría de los reportes utilizan los índices de maloclusión ICON y PAR para realizar las mediciones pre y post-tratamiento y evaluar efectividad del uso de la ortodoncia interceptiva. La extracción de caninos temporales por si sola no previene la impactación de caninos permanentes. La extracción seriada tuvo un tiempo de control sin aparatos más largo, pero menor periodo de tratamiento activo y se indica en pacientes con más de 6 mm de discrepancia negativa dentomaxilar. La mayoría de los estudios muestra un alto nivel de evidencia (53%), pero presentan diferencias en las variables estudiadas y en las modalidades de tratamientos que no los hacen comparables entre ellos. Hay evidencia de que la intervención temprana en niños con maloclusiones dentoalveolares es beneficiosa, mejoran resalte y la alineación anterior maxilar y mandibular. La discrepancia dentomaxilar severa es factible de tratar con extracción seriada. La evidencia es escasa para mordida abierta y malos hábitos. El tratamiento interceptivo requiere largo seguimiento y no elimina la necesidad de tratamiento correctivo. No existe evidencia de que la resolución interceptiva de la mordida cruzada sea positiva.


The aim was to determine the benefit of implementing interceptive orthodontic clinics in infant patient analyzing recent literature about it. We conducted a systematic review of the literature by searching PubMed, SciELO and Cochrane Library for the past 10 years in response to the question: "In children with dentoalveolar malocclusions is it beneficial to implement interceptive orthodontics or is it better to apply a therapy at the end of growth?" Searching words were "interceptive orthodontic", "serial extraction" or its translations in Spanish. We used inclusion and exclusion criteria to find the highest-level evidence. We selected 17 items of which five were clinical trials, six were retrospective cohort, and four were systematic reviews and one clinical case of long standing. Most reports use ICON and PAR index malocclusion for pre and post-treatment and to evaluate the effectiveness of using interceptive orthodontics. Cuspid extraction alone does not prevent permanent canine impaction. The control of serial extraction without braces was longer than with braces, but the active treatment period was shorter. This process is indicated in patients with more than 6 mm dentomaxilar negative discrepancy. Most studies show a high level of evidence (53%), but they differ in some variables and some treatments modalities, which do not make them comparable. There is evidence that early intervention in children with dentoalveolar malocclusions is beneficial, improving over-jet and alignment of anterior maxillary and mandibular. It is feasible to treat severe dentomaxilar discrepancy with serial extraction. The evidence is insufficient to open bite and bad habits. Interceptive treatment requires lengthy follow up and does not eliminate the need for corrective treatment. There is no evidence that the resolution interceptive crossbite is positive.

RESUMO

La falta de parámetros cefalométricos validados a la población infantil de nuestra región para conocer el desarrollo craneofacial, hacen necesario tener mediciones que se aproximen a los diferentes patrones que presenta esta población. Debido a esto, surge el presente estudio de corte transversal de mediciones cefalométricas de niños de 5 años de edad, el cual se realizó con una muestra no probabilística consecutiva, constituida por 30 niños y 30 niñas de escuelas municipales de la ciudad de Temuco en el año 2009 con dentición temporal completa, no mapuches, con simetría facial, líneas medias centradas, con escalón mesial o plano post lácteo recto, sin tratamiento ortodóntico previo y con consentimiento de los padres por escrito. Se midieron 12 parámetros descritos por diferentes autores. Resultaron ser significativos estadísticamente los valores de eje facial y de altura facial posterior según el género. Respecto a los valores de Wits, los resultados muestran que los valores de la mediana para el género masculino es de 1,0 mm mientras que para el género femenino corresponde a un 1,5mm. Al aplicar el coeficiente de correlación de Pearson, para las variables estudiadas se encontró una relación lineal directamente proporcional entre los ángulos SNA y SNB (0,75), SNA y BA-S-Na(0,5) y ángulo ANB y análisis de Wits (0,6); mientras que al relacionar las variables ángulo SNB con ángulo Ba-S-Na(-0,7) la relación lineal es inversamente proporcional. Se concluye que existen diferencias a la norma internacional y se destaca en que a esta edad, los niños chilenos presentan una mandíbula levemente más retroposicionada.


The lack of validated cephalometric parameters in the pediatric population of our region to learn craniofacial development, there is a need to know approximate measurements of different patterns that present in the child population. The present study of cross-sectional cephalometric measurements in five-year-old children, which was performed with a straight non-probability sample, consisting of 30 boys and 30 girls from municipal schools in Temuco in 2009 with full dentition, non-Mapuche with facial symmetry, centered midline, with tray or flat mesial post straight, without prior orthodontic treatment with parental consent in writing. 12 parameters were measured as described by different authors. According to the Student's t tests statistically significant facial axis values and posterior facial height were found according to sex. With respect to the values of Wits, the results show that the median values for male is 1.0 mm while for the female corresponds to 1.5 mm. By applying the Pearson correlation coefficient for the variables studied we found direct proportional linear relationship between SNA and SNB angles (0.75), SNA and BA-S-Na (0.5) and ANB angle and analysis Wits (0.6), while relating the angle variables SNB angle Ba-S-Na (-0.7) the linear relationship is inversely proportional. We conclude that there are differences to the international standard and noted that at this age Chilean children have a jaw slightly in retroposition.

RESUMO

Las alternativas de tratamiento de las maloclusiones de clase II esqueléticas y dentales incluyen las extracciones de dientes permanentes y la distalización de los molares maxilares con aparatos extraorales e intraorales. Estos últimos, no necesitan la cooperación del paciente, además, en ellos se han hecho variaciones importantes en su mecánica y diseño a lo largo de los años. Con el uso de los minitornillos se ha podido eliminar, en gran parte, los efectos de reacción como la vestibularización de los incisivos y la mesialización de los premolares. Este artículo sintetiza una revisión de la literatura de los últimos 20 años de los diferentes diseños y sistemas mecánicos que se han usado con éxito en la distalización de los molares maxilares.


The alternatives of treatment of class II skeletal and dental maloclussions included the extractions of permanent teeth and the maxillary molars distalization by extraoral devices and intraoral devices. The above mentioned, does not need cooperation of the patient. In addition, important variations have been mechanics and design throughout the years. With the miniscrews one could have eliminated, largely, the effects of reaction as the vestibularization of the incisor teeth and the mesialization of the bicuspid. This article is a synthesis of a review of the literature of last 20 years of the different designs and mechanical systems that have been used successfully in the distalization of the maxillary molars.

RESUMO

El cefalograma lateral es una radiografía que se usa rutinariamente en la ortodoncia. Este tipo de radiografía plana es la mejor opción para investigar las características morfométricas de la silla turca, determinando su tamaño y forma y sus eventuales variaciones. Taveras & Wood han descrito un método, para determinar el tamaño de la silla turca en radiografías. Midiendo el mayor diámetro anteroposterior de la silla turca y la profundidad de ella desde el punto más bajo a una línea que conecta la cima del dorso de la silla al tubérculo selar. Esto nos motivó llevar a cabo un estudio de estas características, para lo cual se registraron las correspondientes observaciones en 88 teleradiografias laterales, de las cuales correspondían a 44 individuos adultos jóvenes mapuches y 44 no mapuches, de ambos sexos, todos pertenecientes a la IX Región. El diámetro anteroposterior de la silla turca fue de 12,85 +/- 1,5 mm, con rangos entre 10,05 a 15,95 mm; la profundidad fue de 10,31 +/- 1,3 mm, con rangos de 7,20 a 13,36 mm; en individuos no mapuche el diámetro anteroposterior fue de 12,11 +/- 2,4 mm, con rangos entre 6,72 a 17,06 mm; la profundidad fue de 11,01 +/- 1,4 mm, con rangos de 7,92 a 13,67 mm. El área selar en mapuches fue de 132,4 mm²; y en no mapuches de 133,3 mm². La forma de la fosa fue circular en 36 casos, oval en 30 casos y plana en 22 casos.


The lateral cephalogram is an x-ray routinely used in orthodontics. This type of plane x-ray is the best choice to investigate the morphometric characteristics of the sella turcica, its size and shape, creating a variation. Taveras & Wood described a method to determine the size of the sella in radiography. Measuring the diameter of the anterior sella turcica and the depth of it from the lowest point to a line connecting the top of the back of the sella to the sellar tuber. This led to a study of the present characteristics , which reported observations in 88 lateral teleradiograph takes, of which 44 were young adult Mapuche individuals and 44 non Mapuche of both sexes, all native to the IX Region. The anteroposterior diameter of the sella turcica was 12.85 +/- 1.5mm, ranging from 10.05 to 15.95 mm, the depth was 10.31 +/- 1.3 mm, with ranges of 7.20 to 13.36 mm, in Mapuche individuals anteroposterior diameter was 12.11 +/- 2.4 mm, ranging from 6.72 to 17.06 mm, the depth was 11.01 +/- 1.4 mm, ranging from 7.92 to 13.67mm. Sellar area in Mapuches has been set at 132.4 mm² and non Mapuche of 133.3 mm². The shape of the fossa of the sella turcica was circular in 36 cases, oval in 30 cases and plane in 22 cases.
