RESUMO

OBJECTIVES: To identify and qualify the evidence of published studies evaluating whether rapid maxillary expansion (RME) treatment modifies the head and cervical posture in growing patients. MATERIALS AND METHODS: Electronic database searches were conducted until January 2021 using PubMed/MEDLINE, Embase, Web of Science, Cochrane Library, and LILACS. Grey literature was explored using ClinicalTrials, OpenGrey and Google Scholar. Trials involving participants who underwent RME were included. Risk of Bias (RoB) assessment was conducted using the Cochrane tool for randomized trials and the Methodological Index for Non-randomized Studies (MINORS) for non-randomized trials. The certainty level of evidence was evaluated through the Grading of Recommendations, Assessment, Development and Evaluation tool (GRADE). RESULTS: Six clinical trials were included. The RoB scores had unclear and high risks of bias. Low certainty of evidence suggested that the effects following RME include a decrease in craniocervical angulation, as well as a very low certainty of evidence for a decrease in head elevation, an increase in cervical lordosis, and an increase in the inclination of the cervical spine. CONCLUSIONS: There is low and very low evidence that RME alters the head and cervical posture in growing patients. Further investigation regarding long-term effects, possible changes due to somatic growth, and clinical relevance is needed.

RESUMO

INTRODUCTION: Identifying the stage of midpalatal suture (MPS) fusion is essential for rapid maxillary expansion (RME). The objective of this study was to evaluate the relationship between MPS density ratio and the skeletal response after RME using cone-beam computed tomography (CBCT). METHODS: CBCT scans of 64 patients (age, 13.81 ± 1.68 years; 42 females and 22 males) who underwent RME as part of comprehensive orthodontic treatment were used for this study. Two CBCT records were made at T1 (pre-RME) and T2 (post-RME). MPS density was assessed by gray scale and the skeletal effects through linear measurements: greater palatine foramina, the width of the nasal cavity (NW), infraorbital foramina. The data were collected at 4 different times: baseline, 24 hours, 48 hours, and 4 weeks. RESULTS: There was no statistically significant correlation between MPS density ratio and greater palatine foramina or infraorbital foramina. Negative correlations with MPS density ratio are presented with the difference of age post-RME and pre-RME (r = -0.46, P = 0.033) in males, and NW (r = -0.41, P = 0.007) in females. A significant association between gender and the MPS density ratio was found (P = 0.015) in females. CONCLUSIONS: There is a weak negative correlation between the MPS density ratio and the difference of age post-RME and pre-RME in males and the NW in females. Females presented greater density ratios than males. MPS density ratio through CBCT does not appear to be an adequate parameter to predict the skeletal effect in adolescent patients and young adults.

RESUMO

OBJECTIVES: Describe and compare harmful periodontal effects as a consequence of maxillary expansion in adult patients with different types of anchorage devices in non-surgical expanders with skeletal anchorage and surgically assisted maxillary expansion. MATERIALS AND METHODS: An exhaustive search was carried out on the electronic databases PubMed (MEDLINE), Embase, Cochrane and LILACS. Additionally, journal references and grey literature were searched without any restrictions. After the selection and extraction process; risk of bias was assessed by the ROB-1 Cochrane tool and Newcastle-Ottawa Scale (NOS) for randomized trials and cohort studies, respectively. RESULTS: Of 621 studies retrieved from the searches, six were finally included in this review. One of them presented a low risk bias, while five were excellent respective to selection, comparability and outcomes. Results showed that maxillary expansion in adults using non-surgical expanders (bone-borne or tooth-bone-borne with bicortical skeletal anchorage) produce less harmful periodontal effects, such as: alveolar bending with an average range from 0.92° to 2.32°, compared to surgically assisted maxillary expansion (tooth-borne) of 6.4°; dental inclination with an average range from 0.07° to 2.4°, compared to surgically assisted maxillary expansion (tooth-borne) with a range from 2.01° to 5.56°. CONCLUSIONS: Although limited, the current evidence seems to show that the bone-borne or tooth-bone-borne with bicortical skeletal anchorage produces fewer undesirable periodontal effects.

RESUMO

Aim: To determine total fluoride (TF) concentration in Na2FPO3/Ca-based toothpastes, using fluoride ion selective electrode (F-ISE) by the direct technique, it is necessary to use acid (Ac+) to hydrolyze the FPO32- ion and to dissolve insoluble fluoride salts bound to the abrasive. For NaF/silica-based toothpastes, the use of acid is not necessary (Ac-) and a simplified protocol could be followed. Methods: Thus, we evaluated TF concentration in seven brands of NaF/silica-based toothpastes, following the validated conventional Cury's protocol (Ac+) or a simplification of this protocol (Ac-).Fluoride was analyzed with ISE calibrated with fluoride standard solutions prepared in the same conditions as the samples (Ac+ or Ac-). Results: The mean (±SD; n=21) of TF concentrations (µg F/g) found by Ac+ (971.3±191.2) and Ac- (982.4±201.3) protocols were not statistically different (t test, p=0.22). The TF concentrations found agree with those declared by the manufacturers, except for one toothpaste imported from China. Conclusion: The findings suggest that the determination of fluoride in NaF/silica-based toothpastes can be accurately made using a simplified protocol of analysis

RESUMO

Los caninos maxilares son unos de los dientes que se impactan con mayor frecuencia en el arco dentario después de los terceros molares. Las impactaciones palatinas son más prevalentes (85%) que las vestibulares (15%). A pesar de que la incidencia de impactación es de 1 en 100, este rango suele ser mayor en pacientes que buscan tratamientos ortodónticos alcanzando el 23,5%. Resulta sumamente importante definir sus características anatómicas, posición, angulación y relación con los dientes vecinos y estructuras adyacentes en la fase diagnóstica. Los primeros protocolos de evaluación fueron realizados utilizando imágenes bidimensionales, sin embargo, con el creciente desarrollo tecnológico, actualmente contamos con imágenes tridimensionales que según la literatura brindan ventajas sobre las imágenes tradicionales. Es así como ya se han desarrollado protocolos utilizando tomografías volumétricas.Desafortunadamente, todos los métodos disponibles en múltiples publicaciones se encuentran dispersos, por lo que propósito de esta revisión es recopilar evidencia científica relacionada con los métodos diagnósticos más utilizados en la evaluación de imágenes para optimizar el plan de tratamiento y pronóstico de caninos maxilares impactados.


Maxillary canines are one of the most frequently impacted teeth in the dental arch, second only to thrid molars. Palatine impactations are more prevalent (85%) than buccal (15%). Although the incidence of impactations is about 1 in 100 in the general population, the ratio tends to be much higher in the orthodontic practicereaching 23.5%. It is important to define the canine anatomic characteristics, position, angulation and relation with the adyacent teeth and structures in the diagnostic phase. The first evaluation protocols were performed using bidimensional images, nevertheless, with the recent technological development, today we can count with tridimensional images that according to literature present advantages over traditional images. That is why protocols in tridimensional images are being developed. Unfortunately, all the available methods in different publications are scattered,so the purpose of this review was to compile scientific evidence related to the most widely used diagnosis methods of imaging assessment to optimize the treatment plan and prognosis of maxillary canine impactations.

RESUMO

Determinar la correlación de la percepción estética de la sonrisa y la inclinación del incisivo central superior entre pacientes y estudiantes del último año de la Universidad San Martin de Porres (USMP). Material y métodos: Estudio descriptivo, observacional, transversal y prospectivo. La muestra estuvo constituida por 100 personas (50 estudiantes y 50 pacientes) que acudieron a la Clínica Especializada de Odontología de la USMP, entre los 18 y 35 años de edad. Se les mostró 3 fotografías de una mujer (22 años de edad) de perfil sonriendo, que fueron evaluadas por un juicio de expertos. Dichas fotografías, fueron manipuladas mediante el programa de software de edición de imágenes Adobe Photoshop (Adobe Photoshop CS6 Versión 13.0.1) para simular inclinaciones de +15º labial, 0º inicial (buena inclinación del incisivo superior según evaluación cefalométrica), -15º lingual. El valor de la percepción de las diferentes fotografías fue determinado mediante una escala visual análoga (EVA). Resultados: Se encontró que la inclinación inicial (0ºgrados) del incisivo central superior, en una vista de perfil, es percibida agradable para los pacientes y estudiantes consultados de la USMP (p< 0,05). No existió asociación estadísticamente significativa según el sexo del encuestado (p>0,05). Conclusiones: Existe una alta correlación entre la percepción estética de la sonrisa y la inclinación del incisivo central superior en pacientes y estudiantes del presente estudio.

RESUMO

El periodonto es la estructura a través de la cual el ortodoncista mueve los dientes, por lo tanto el éxito de un tratamiento ortodóncico depende en parte de la integridad de la salud de los tejidos periodontales. Como ciertos movimientos ortodóncicos pueden afectar el periodonto y los tejidos gingivales, es básica una valoración periodontal previa al tratamiento. Problemas periodontales no diagnosticados y/o no tratados a tiempo, como defectos mucogingivales y recesiones gingivales, pueden empeorar con la terapia ortodóncica. El presente caso describe a una paciente de sexo femenino de 13 años de edad con recesión gingival a nivel de piezas 31 y 41 y apiñamiento dentario. El tratamiento periodontal consistió en un injerto de encía libre para aumentar la encía queratinizada y aumento de fondo de surco vestibular antes de iniciar el tratamiento de ortodoncia. El objetivo de este reporte de caso es presentar el manejo adecuado en la prevención y control de las recesiones gingivales para asegurar un mejor pronóstico a través de un trabajo interdisciplinario entre periodoncia y ortodoncia.


The periodontium is the structure through which the orthodontist moves your teeth, so the success of orthodontic treatment depends in part on the integrity of the health of periodontal tissues. Because some orthodontic tooth movement may affect the periodontal and gingival tissues, periodontal assessment is essential prior to orthodontic treatment. Undiagnosed periodontal problems and / or untreated in time, as Mucogingival defects and gingival recession may worsen with orthodontic treatment. This case describes a female patient 13 years of age with gingival recession at parts 31 and 41 and dental crowding. Periodontal treatment consisted of a free gingival graft to increase the gingiva and increased background surcus vestibular before starting orthodontic treatment. The aim of this case report is to present the best conduct to be taken in the prevention and control of gingival recessions to ensure a better outcome through a management interdisciplinary between periodontics and orthodontics.

RESUMO

El objetivo de este estudio fue comparar las características craneofaciales y dentarias de niños con maloclusión Clase II-1 nacidos de ancestros y residentes a distintas altitudes geográficas. Se analizaron los datos cefalométricos de 150 niños de 8 a 12 años de edad, 50 niños de cada unade las ciudades de Lima (150 msnm), Cusco (3,800 msnm), y Cerro de Pasco (4250 msnm) quienes se habían seleccionado verificando que tuvieran estado nutricional normal mediante el parámetro talla /edad. El Análisis de varianza (ANOVA) muestra una diferencia estadísticamente significativa para la AFAI, (p<0,05); y altamente significativa para las demás características cefalométricas (p<0,01) entre los distintos grupos analizados. En conclusión, la relación esquelética clase II se debe principalmente a una combinación de protrusión maxilar y retrusión mandibular en las tres ciudades. Sin embargo, en los niños de las ciudades de altura, hay una alta prevalencia de casos de protrusión ó retrusión pura, con retrusión y palatinización acentuada de los incisivos superiores en niños de las ciudades de altura.


The aim of this study was to compare the dental and craniofacial characteristics of children withClass II-1 malocclusion born of ancestors living at different altitudes and locations. Cephalometric data were analyzed from 150 children aged from 8 to 12 years old, 50 children from the cities of Lima (150 m), Cusco (3,800 m) and Cerro de Pasco (4250 m) who were selected by checkingwho had normal nutritional status with height / age parameter. Analysis of variance (ANOVA) showed a statistically significant difference for AFAI (p<0.05) and highly significant for the other cephalometric characteristics (p<0.01) between the diferentes groups analized. In conclusion, the skeletal Class II is mainly due to a combination of maxillary protrusion and mandibular retrusión in the three cities, with a high prevalence of cases with protrusion or pure retrusión with retrusión and palatal inclination of maxillary incisors in the cities of high altitude.

RESUMO

El propósito de este estudio, in vitro, fue evaluar el efecto erosivo de tres bebidas carbonatadas sobre la superficie del esmalte dental. Se utilizaron 60 especímenes divididos en cuatro grupos de los cuales tres fueron expuestos durante un minuto a la acción de las bebidas carbonatadas, seguido por tres minutos de inmersión en saliva artificial. Este ciclo se repitió durante 20minutos. El grupo control negativo fue inmerso en agua destilada. El efecto erosivo se evaluó mediante el método de dureza Vickers antes y después de ser sometidos a la acción de las bebidas.Al aplicar la prueba t de Student se encontró diferencia significativa (p<0,05) entre los valoresde microdureza inicial y final de los especimenes, siendo mayor el efecto erosivo de la bebida Kola Real®, similar a la Coca Cola®, mientras que la Inca Kola® presentó el menor efectoerosivo.


The aim of this in vitro study was to assess the effect of three erosive carbonated soft drinksover tooth enamel surface. Sixty enamel specimens were divided into four groups. Three groupswere exposed to carbonated soft drinks for one minute, followed by three minutes of artificialsaliva. This cycle was repeated every 20 minutes. The negative control group was immersed indistilled water. Vickers hardness method was used to determine the for erosive effect on specimensbefore and after they were exposed to soft drinks., A significant difference (Student t-testp<0.05) was found between initial and final microhardness values of the specimens exposed tocarbonated soft drinks. In conclusion, Kola Real® carbonated soft drink showed an erosiveeffect similar to Coca-Cola®, while Inca Kola® had the lowest erosive effect.
