RESUMEN

This dataset features 200 sagittal projection images derived from Cone Beam Computed Tomography (CBCT) scans, corrected according to the Natural Head Position (NHP) guidelines proposed by Fredrik Lundström and Anders Lundström. The images originate from orthodontic patients in Cali, Valle del Cauca, Colombia, encompassing both initial phases and ongoing treatments. The dataset is divided into two groups: 100 images from female subjects (CoF) and 100 from male subjects (CoM), facilitating gender-specific studies. The dataset is accompanied by an Excel file ``Data info.xlsx'' that details the rotation angles in the axial (Yaw), coronal (Roll), and sagittal (Pitch) planes, along with the pixel size and image dimensions. This detailed documentation supports the replication of studies and aids in the interpretation of cephalometric analyses. Corrections made to align the images with NHP standards involve adjustments in the three main anatomical planes using points from the frontozygomatic suture (Fz) in the axial and coronal planes, and sella (S) and nasion (N) for the sagittal plane.

RESUMEN

OBJECTIVE: To evaluate a protocol for bonding metallic brackets after bleaching with hydrogen peroxide (HP). METHODS: 60 extracted maxillary premolar were randomly divided into an unbleached control group and two groups bleached with a solution of 35% hydrogen peroxide prior to bonding. The teeth in one of the treated groups were bonded immediately after bleaching; while the other group was treated with 10% sodium ascorbate immediately after bleaching and before bonding. The teeth in all groups were stored in an artificial saliva solution for 7 days after bonding. The shear bond strength data was measured in megapascals (MPa) and the fail attempts were verified. The significance level was established at p< 0.05. RESULTS: The unbleached group, in which brackets were bonded to untreated enamel, had the highest bond strength values (11.0 ± 5.7MPa) in comparison to the bleached group (7.14 ± 40MPa), in which brackets were bonded to recently bleached enamel. Slightly improved bond strength was observed in the antioxidant group (8.13 ± 5.4MPa), in which the teeth were bleached and then the antioxidant was applied to the teeth before bonding. Unbleached and bleached groups showed statistically significant difference for shear bond strength (p=0.03) and load strength (p=0.03); no significant differences were noted between unbleached and antioxidant groups (p=0.52). CONCLUSION: The antioxidant treatment applied immediately after bleaching was effective in reversing the reduction in shear bond strength of brackets after tooth bleaching.

RESUMEN

AIM: We aimed to evaluate the correlation between the polymorphism of the interleukin 1-Beta (IL1-ß, +3954 C>T) and tooth movement, in a group of Colombian patients undergoing surgically accelerated orthodontic tooth movement. METHODS: The study was nested to a controlled clinical trial. Blood samples were taken from 11 women and 29 healthy Colombian male volunteers between 18 and 40 years old, after 1 year of starting orthodontic treatment. The patients presented malocclusion class I, with grade II or III. To detect the genetic polymorphism of the nucleotide +3954 C to T in the IL-1ß gene, we used a real-time PCR assay. RESULTS: Eleven individuals presented the allele 2 (T) heterozygous with the allele 1 (T/C) and 19 individuals were homozygous for the allele 1 (C/C). When analyzing the presence of the SNP, no significant differences were found in any of the variables. The best treatment was reflected in Group 3 (selective upper and lower alveolar decortication and 3D collagen matrix) and Group 4 (only selective alveolar decortication in the upper arch, with 3D collagen matrix), with 27% and 35% more speed respectively than in the control group. CONCLUSIONS: Our analyses indicated that a reduction in the total treatment time can be mostly potentiated by using decortication and collagen matrices and not for the presence of the allele 2 in the IL-1ß. Nevertheless, it is important that further studies investigate if the polymorphism could be associated with the speed of tooth movement and analyze the baseline protein levels.

OBJETIVO: Evaluar la correlación entre el polimorfismo de la interleucina 1-Beta (IL1-ß, +3954 C> T) y el movimiento de los dientes, en un grupo de pacientes colombianos sometidos a un movimiento dental ortodóncico acelerado quirúrgicamente. MÉTODOS: Este fue un estudio secundario derivado de un ensayo clínico aleatorio controlado. Se tomaron muestras de sangre de 11 mujeres y 29 voluntarios varones colombianos sanos entre 18 y 40 años, después de 1 año de comenzar el tratamiento de ortodoncia. Los pacientes presentaron maloclusión clase I, con grado II o III. Para detectar el polimorfismo genético del nucleótido +3954 C a T en el gen IL-1ß, se usó un ensayo de PCR en tiempo real. RESULTADOS: 11 individuos presentaron el alelo 2 (T) heterocigoto con el alelo 1 (T / C) y 19 individuos fueron homocigotos para el alelo 1 (C / C). Al analizar la presencia del SNP, no se encontraron diferencias significativas en ninguna de las variables. El mejor tratamiento se reflejó en el Grupo 3 (decorticación alveolar superior e inferior selectiva y matriz de colágeno 3D) y el Grupo 4 (solo decorticación alveolar selectiva en el arco superior, con matriz de colágeno 3D), con un 27% y un 35% más de velocidad, respectivamente, que en el grupo de control. CONCLUSIONES: Los análisis indicaron que una reducción en el tiempo total de tratamiento puede potenciarse principalmente mediante el uso de decorticación y matrices de colágeno y no por la presencia del alelo 2 en la IL-1ß. Sin embargo, es importante que otros estudios investiguen si el polimorfismo podría estar asociado con la velocidad del movimiento de los dientes y analizar los niveles de proteína de referencia.

RESUMO Objetivo: Avaliar um protocolo para colagem de braquetes metálicos após clareamento com peróxido de hidrogênio (PH). Método: Sessenta pré-molares superiores extraídos foram aleatoriamente divididos em um Grupo Controle (sem clareamento) e dois grupos que receberam clareamento, antes da colagem, com solução de peróxido de hidrogênio a 35%. Em um dos grupos tratados (Grupo Clareamento), os braquetes foram colados imediatamente após o clareamento, enquanto o outro (Grupo Antioxidante) foi tratado com ascorbato de sódio a 10%, imediatamente após o clareamento e antes da colagem. Os dentes, em todos os grupos, foram armazenados em saliva artificial por 7 dias após a colagem. As informações relativas à resistência da colagem foram registradas em megapascals (MPa) e as tentativas fracassadas foram verificadas. O nível de significância foi estabelecido em p < 0,05. Resultados: O Grupo Controle, no qual os braquetes foram colados ao esmalte não clareado, apresentou os valores mais altos de força de adesão (11,0 ± 5,7 MPa), em comparação ao Grupo Clareamento (7,14 ± 40 MPa), no qual os braquetes foram colados ao esmalte recém-clareado. Uma suave melhora na força de adesão foi observada no Grupo Antioxidante (8,13 ± 5,4 MPa), no qual, após os dentes serem clareados, foi aplicado antioxidante aos dentes, antes da colagem. Os Grupos Controle e Clareamento apresentaram uma diferença estatisticamente significativa para a resistência da colagem (p =0,03) e a resistência à carga (p= 0,03); porém, nenhuma diferença significativa foi notada entre os Grupos Controle e Antioxidante (p =0,52). Conclusão: O tratamento antioxidante aplicado imediatamente após o clareamento foi efetivo em reverter a diminuição da resistência da colagem dos braquetes após o clareamento dentário.

RESUMEN

OBJECTIVE: The purpose of this study involves describing the facial morphology of a Colombian population with three-dimensional (3D) imaging, and comparing their facial morphology with the Caucasian to create a database for this ethnicity. MATERIALS AND METHODS: The study, which included 135 subjects selected from the Valle University in Cali, Colombia, and 535 Caucasian subjects selected from the FaceBase-Data (1U01DE024449-01), was funded by the National Institute of Dental and Craniofacial Research. All images were taken in the natural head position (NHP) and captured using a stereo-photogrammetric camera system (3dMDface) to obtain a 3D image of each patient. The subjects were between 19 to 31 years of age, with a normal body mass index (BMI), and no craniofacial deformities. All images were plotted and analyzed using the 3dMDVultus software to calculate linear and angular measurements. Standard deviation (SD) and means were calculated for each measurement and analyzed using t-test for different samples. RESULTS: The Hispanic population had wider eyes, more protruded upper and lower lips, wider face, and greater mandibular width. Caucasian females had a more acute full profile, larger middle third, and less protrusive lips. Understanding the facial morphology of different populations would help to establish a better diagnosis and treatment planning for each ethnicity. CONCLUSIONS: From this study, the following conclusions may be drawn:1. The mean values of Colombian males showed greater measurements than females in the majority of measurements.2. Caucasian females had a more acute full profile, larger middle and lower third, and less protrusive lips.3. This study showed significant ethnic differences in the linear and angular measurements, showing us the importance of considering these findings in the diagnosis and treatment planning when a Hispanic population is involved. Soft tissue values should reflect the norms according to each ethnic population in order to achieve treatment goals.

RESUMEN

RESUMEN Desde que se inició su reporte a nivel mundial en 1975 por la Organización Mundial de la Salud, la obesidad se ha comportado como una pandemia. Datos de 2016 muestran que un 13 % del total de la población mundial adulta es obesa. Esta pandemia tiene efectos a nivel sistémico muy conocidos, como hipertensión arterial, diabetes, accidentes cerebrovasculares, enfermedades digestivas, distintos tipos de cáncer, osteoporosis y osteoartritis. También tiene efectos menos investigados y poco conocidos, como el crecimiento de los maxilares, caries y enfermedades periodontales. Existen reportes de los efectos a nivel del tejido óseo que tiene la obesidad, tanto en la osteoblastogénesis como en la osteoclastogénesis; en donde los adipocitos generan alteraciones de los niveles de la hormona leptina, adiponectina y algunas citoquinas, teniendo como resultado la disminución de la masa ósea. Es por todo lo anterior que mediante una revisión bibliográfica en las bases de datos Embase, PubMed, ScienceDirect y SCIELO, utilizando los términos normalizados skull, bone, obesity, growth y las palabras clave en inglés obese, craniofacial, development, morphometry; se encontró que la literatura científica reporta diferentes estudios en personas obesas, en los que se ha demostrado que los individuos en etapa de adolescencia presentan cambios morfológicos específicos, como el aumento de la base anterior de cráneo, longitud de uno o ambos maxilares y aumento en la longitud del cuerpo mandibular.

ABSTRACT Obesity, since its worldwide report in 1975 by the World Health Organization; has behaved like a pandemic. Data from 2016 show that 13 % of the adult world population is obese. This pandemic has well-known systemic effects such as high blood pressure, diabetes, stroke, digestive diseases, various types of cancers, osteoporosis and osteoarthritis. It also has less investigated and little-known effects, such as maxillary growth, caries and periodontal diseases. There are reports of the effects on bone tissue of obesity, both in osteoblastogenesis and in osteoclastogenesis; in which the adipocytes generate alterations in the levels of the hormone leptin, adiponectin and some cytokines, resulting in a decrease in bone mass. It is for all of the above, that through a systematic review in the databases: Embase, PubMed, ScienceDirect and SCIELO; using the normalized terms: skull, bone, obesity, growth; and the key words in English: obese, craniofacial, development, morphometry. It was found that the scientific literature shelters different studies in obese individuals, where it has been shown that individuals in the adolescence stage present specific morphological changes such as increased anterior skull base, length of one or both maxillary and increase on the length of the mandibular body.

RESUMEN

ABSTRACT Introduction: the aim of this systematic review is to explore the published literature to analyze the relationship between polymorphism of interleukin 1-beta (IL-1β) and orthodontics. Methods: the search strategy developed for Medline, Scopus and Embase was used, verifying search records and selecting articles according to the guidelines set forth by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two researchers evaluated studies in humans undergoing orthodontic treatment that evaluate IL-1β polymorphism, movement speed and/or root resorption, including clinical trials, case-control studies, cross-sectional studies, and cohort studies, published up to April 2017. Results: of the 123 relevant articles identified, 9 studies published between 2001 and 2016 were included in the detailed analysis. Studies on tooth movement generally agree that there is an increase in IL-1β levels in the first hours after starting the orthodontic treatment. Conclusion: an association of IL-1β polymorphism with external root resorption and tooth movement speed was found.

RESUMEN Introducción: el objetivo de esta revisión sistemática es analizar, a través de la literatura publicada, la relación entre el polimorfismo de la interleuquina 1 beta (IL-1β) y la ortodoncia. Métodos: se aplicó la estrategia de búsqueda desarrollada para Medline, Scopus y Embase y se verificaron los registros de la búsqueda y los artículos seleccionados de acuerdo a los lineamientos de la declaración para Revisiones Sistemáticas y Metaanálisis (PRISMA). Dos investigadores evaluaron los estudios en humanos sometidos a tratamiento de ortodoncia, donde se evalúan el polimorfismo de la IL-1β y la velocidad de movimiento y/o resorción radicular, como ensayos clínicos, estudios de casos y controles, estudios transversales o estudios de cohortes, publicados hasta abril de 2017. Resultados: de los 123 estudios relevantes identificados, 9 de ellos, publicados entre 2001 y 2016, fueron incluidos en el análisis detallado. Los estudios de movimiento dental concuerdan en el aumento de los niveles de IL-1β en las primeras horas de inicio del tratamiento ortodóncico. Conclusión: se encontró asociación del polimorfismo de la IL-1β con la resorción radicular externa y la velocidad de movimiento dental.

RESUMEN

In this report, we describe the successful use of alternate rapid maxillary expansions and constrictions with a hybrid hyrax-mandibular miniplate combination and simultaneous orthodontic treatment for the management of severe Class III malocclusion due to maxillary hypoplasia in an 11-year-old girl. The devices were removed after 20 months of treatment, and the family was instructed about a careful control and retention program that should be followed in accordance with the patient's growth. The final result included the correction of Class III malocclusion with adequate function and excellent facial esthetics, which restored the patient's self-esteem and provided personal motivation. The outcomes showed good stability after 24 months of retention. The decrease in the duration of active treatment is the most important finding from the present case. Considering that facial esthetics in adolescence is a determining factor for the development of a personality and interpersonal relationships, we recommend the use of this protocol for growing patients, who will exhibit not only an improved physical appearance but also a better quality of life.

RESUMEN

The aim of this study was to assess whether the application of low-level laser therapy (LLLT) during the first stage of orthodontic treatment has an effect on local bone resorption and is detectable at the systemic level by measuring deoxypyridinoline levels (Pyrilinks) in urine. This was a randomized (1:1), double-blind, active-controlled, parallel-group trial. 28 adult patients who were going to start orthodontic treatment were randomly divided into the control group (n: 13) and the experimental group (n: 15), the latter of which received LLLT. All of the subjects underwent testing of urine samples: the first one on the day before the beginning of orthodontic treatment (T0), and the second one 5 days after bracket placement to measure Pyrilinks values (Dpd/Cr) in urine. Group differences were evaluated with Student's paired t-test. At the beginning of the study, the Pyrilinks were in the normal range for 53.57 % of the patients, and 46.43 % had elevated values according to the normal ranges. Only taking into account the normal values at (T0), the average Pyrilinks for control group (T0) were 5.75± 1.20 nM/mM, (T1): 6.02±3.00 nM/mM. For experimental group, (T0) was 5.71± 0.72, and it was 6.63± 0.73 in (T1).There were no significant differences in the Pyrilinks changes. (p= 0.75). In the experimental group levels raised statistically significant (p = 0.009). LLLT on patients starting orthodontic treatment with normal Pyrilinks levels have a statistically significant increment on their levels 5 days post irradiation.

El objetivo de este trabajo fue evaluar si la aplicación de la terapia láser de bajo nivel (TLBN) durante la primera etapa del tratamiento ortodóncico tiene un efecto sobre la resorción ósea local y es detectable a nivel sistémico midiendo los niveles de desoxipiridinolina en la orina. Se trató de un ensayo aleatorizado (1:1), doble ciego, controlado de forma activa y paralelo. 28 pacientes adultos que iban a iniciar el tratamiento de ortodoncia se dividieron al azar en el grupo control (n: 13) y el grupo experimental (n: 15), el último de los cuales recibió TLBN. Todos los sujetos fueron sometidos a pruebas de muestras de orina: la primera en el día anterior al inicio del tratamiento ortodóncico (T0) y la segunda 5 días después de la colocación del bracket para medir los valores de Pyrilinks (Dpd / Cr) en la orina. Las diferencias grupales se evaluaron con la prueba t de Student pareada. Al inicio del estudio, los Pyrilinks estaban en el rango normal para 53,57 % de los pacientes, y 46,43 % tenían valores elevados según los rangos normales. Sólo teniendo en cuenta los valores normales en (T0), los Pyrilinks medios para el grupo de control (T0) fueron 5,75 ± 1,20 nM / mM, (T1): 6,02 ± 3,00 nM / mM. Para el grupo experimental, (T0) fue de 5,71 ± 0,72, y fue de 6,63 ± 0,73 en (T1). No hubo diferencias significativas en los cambios de Pyrilinks. (P = 0,75). En el grupo experimental los niveles aumentaron estadísticamente (p = 0,009). LLLT en los pacientes que comienzan el tratamiento ortodóncico con niveles normales de Pyrilinks tienen un incremento estadísticamente significativo en sus niveles 5 días después de la irradiación.

RESUMEN

The aim of this study was to describe periodontal effects and treatment time of Periodontally Accelerated Osteogenic Orthodontics (PAOO) and to determine if Deoxypyridinoline could be used as a biochemical marker of bone turnover in patients undergoing PAOO. We compared 5 patients undergoing PAOO (5 males, mean age: 29.6±9.8 years) with 5 control patients undergoing self-ligating orthodontics (5 males, mean age: 28.5±6.3 years). All patients were evaluated using panoramic and lateral x-rays and CBCT and randomly selected in experimental and control groups. Both groups underwent self-ligating orthodontics using Damon Q braces. Only the experimental group underwent PAOO. The patients were evaluated periodontally at T1 (before surgery and orthodontic movement) and T2 (after orthodontic treatment). The total treatment time for the experimental group was 8.2±3.3 months and for the control group was 13.4±7.3 months. There were no differences between T2-T1 periodontal variables in either of the groups. Gingival recession was 0.49±0.26 mm at T1 and 0.42±0.3 mm at T2 in the experimental group. Gingival recession was 0.55±0.31 mm at T1 and 1.19±0.24 mm at T2 in the control group. Deoxypyridinoline urine levels showed great variance between individuals and between groups. There is a reduction in treatment time for patients undergoing PAOO with DAMON Q braces. There is no difference in the periodontal condition between PAOO and conventional orthodontics.

El objetivo de este estudio fue describir los efectos periodontales y el tiempo de tratamiento de ortodoncia osteogénica periodontalmente acelerada (OOPA) y para determinar si desoxipiridinolina podría ser utilizado como un marcador bioquímico de recambio óseo en pacientes sometidos a OOPA. Se estudiaron 5 pacientes sometidos a OOPA (hombres, edad media de 29,6±9,8 años) y 5 pacientes control sometidos a ortodoncia de autoligado (hombres, edad media de 28,5±6,3 años). Todos los pacientes fueron evaluados utilizando radiografías panorámicas y laterales, tomografía computadorizada de haz cónico, y luego distribuidos aleatoriamente en grupos experimentales y de control. Ambos grupos fueron sometidos a la ortodoncia de autoligado utilizando dispositivos ortodónticos Damon Q. Sólo el grupo experimental fue sometido a OOPA. Los pacientes fueron evaluados periodontalmente en T1 (antes de la cirugía y el movimiento de ortodoncia) y T2 (después de un tratamiento de ortodoncia). El tiempo total de tratamiento para el grupo experimental fue de 8,2±3,3 meses y para el grupo control 13,4±7,3 meses. No hubo diferencias entre las variables periodontales T2-T1 en cualquiera de los grupos. La recesión gingival en el grupo experimental fue de 0,49±0,26 mm en T1 y 0,42±0,3 mm en T2. En el grupo control, la recesión gingival fue 0,55±0,31 mm en T1 y 1,19±0,24 mm en T2. Los niveles de desoxipiridinolina en orina mostraron gran variación entre individuos y entre grupos. Hubo una reducción en el tiempo de tratamiento para los pacientes sometidos OOPA con dispositivos ortodónticos Damon Q. No hubo diferencia en la condición periodontal entre pacientes sometidos a OOPA y ortodoncia convencional.

RESUMEN

Para diagnosticar correctamente la periodontitis agresiva (PA) se debe tener en cuenta la información obtenida de la entrevista con el paciente, examen clínico periodontal, radiográfico y de laboratorio, según necesidad. El tratamiento de la PA va encaminado a la reducción o eliminación de los agentes causales, manejo de los factores de riesgo y la corrección de los efectos de la enfermedad sobre los tejidos periodontales. Cuando se pretende realizar un tratamiento de ortodoncia en un paciente con PA, se requiere una evaluación detallada por ambas especialidades. Este artículo describe la terapia periodontal y ortodóncica combinada en cuatro pacientes jóvenes con periodontitis agresiva localizada (PAL) y periodontitis agresiva generalizada (PAG). En primer lugar, se llevó a cabo un tratamiento periodontal completo. Una vez que se confirmó la ausencia de inflamación y la estabilidad del periodonto, se inició el tratamiento de ortodoncia utilizando fuerzas ligeras acompañadas de un monitoreo periodontal, alcanzando los objetivos estéticos y funcionales planteados al inicio del tratamiento.

Accurate diagnosis of aggressive periodontitis (AP) requires taking into account information obtained from the interview with the patient and from clinical periodontal examination, radiographic evaluation, and laboratory tests when needed. AP treatment is aimed at reducing or eliminating triggering agents, managing risk factors, and correcting effects on periodontal tissues. Before starting orthodontic treatment in an AP patient, it is necessary to perform a detailed evaluation by both specialties. This article describes a combined periodontal-orthodontic therapy in four young patients with localized aggressive periodontitis (LAP) and generalized aggressive periodontitis (GAP). A complete periodontal treatment was first conducted. After completely reducing inflammation and stabilizing the periodontium, the clinicians started the orthodontic treatment by using moderate forces along with periodontal monitoring, thus reaching the aesthetic and functional objectives set when treatment started.

RESUMEN

INTRODUCTION: Becker muscular dystrophy is an X-chromosomal linked anomaly characterized by progressive muscle wear and weakness. This case report shows the orthodontic treatment of a Becker muscular dystrophy patient with unilateral open bite. METHODS: To correct patient's malocclusion, general anesthesia and orthognathic surgery were not considered as an option. Conventional orthodontic treatment with intermaxillary elastics and muscular functional therapy were employed instead. RESULTS: After 36 months, open bite was corrected. The case remains stable after a 5-year post-treatment retention period. .

INTRODUÇÃO: a distrofia muscular de Becker é uma anomalia ligada ao cromossomo X, caracterizada por desgaste muscular progressivo e fraqueza.
