RESUMO
Introducción: Diversos estudios evidencian que las desarmonías del esqueleto provocan disfunciones temporomandibulares, pues la oclusión dentaria condiciona la posición de los cóndilos en la cavidad glenoidea. Los requisitos del tratamiento ortodóncico incluyen lograr una oclusión estable y equilibrada, una estética facial óptima y el funcionamiento saludable de la articulación temporomandibular. Objetivo: Describir los resultados obtenidos con los bloques gemelos en pacientes con síndrome de clase II, división 1, con trastornos temporomandibulares. Métodos: Se realizó un estudio descriptivo en los pacientes que ingresaron a la consulta de ortodoncia del policlínico "Juan Manuel Páez Inshausty", con edades entre 11 y 14 años, con síndrome de clase ΙΙ, división 1 y trastornos temporomandibulares, en el período comprendido entre febrero 2017 y enero 2018. Se describen 8 pacientes, con el análisis del índice de Helkimo al inicio y a los seis meses de instalados los bloques gemelos básicos. Resultados: Predominaron los pacientes leves con un 62,5 por ciento y el 87,5 por ciento presentó alteración en el funcionamiento de la articulación temporomandibular. A los 6 meses de tratamiento, se encontró que 7 estaban asintomáticos y solo un paciente persistía con alteraciones de la función de la articulación temporomandibular. Conclusiones: La mayoría de los pacientes pasaron a estar asintomáticos a los seis meses del tratamiento con los bloques gemelos(AU)
Introduction: Several studies show that disharmonies of the skeleton cause temporomandibular dysfunctions, since the dental occlusion determines the position of the condyles in the glenoid cavity. The requirements of orthodontic treatment includes achieving stable and balanced occlusion, optimal facial aesthetics and healthy functioning of the temporomandibular joint. Objective: To describe the results obtained with the twin blocks in patients with class II syndrome, division 1, with temporomandibular disorders. Methods: A descriptive study was carried out in the patients who entered the orthodontic clinic of the "Juan Manuel Páez Inshausty" polyclinic, aged between 11 and 14 year old, with class II syndrome, division 1 and temporomandibular disorders, in the period included between February 2017 and January 2018. 8 patients are described, with the analysis of the Helkimo index at the beginning and six months after the basic twin blocks were installed. Results: Mild patients predominated with 62.5 percent and 87.5 percent presented alteration in the temporomandibular joint function. After 6 months of treatment, 7 were found to be asymptomatic and only one patient persisted with alterations in temporomandibular joint function. Conclusions: Most patients became asymptomatic six months after treatment with the twin blocks

La investigación trauma dental. Relación con hábitos bucales deletéreos en la Isla de la Juventud. Se realizó para determinar la relación de los traumatismos dentarios con los hábitos bucales deletéreos en niños de 3 a 14 años. El estudio fue observacional descriptivo prospectivo transversal, el universo fue de 1630 niños, y una muestra de 520 pacientes. Para determinar la frecuencia de los traumatismos dentarios según la edad y caracterizar a los pacientes afectados por traumatismos dentarios en cuanto a la presencia de hábitos deletéreos. Se aplicó la prueba de Chi cuadrado (X2) y odds ratio, para determinar el nivel de asociación. El grupo etario de 6 a 11 años fue el más afectado por traumas con 14.2 por ciento. El hábito deformante que tuvo mayor grado de asociación con el trauma dental fue la succión digital, seguido del tete y posteriormente la respiración bucal(AU).
The research Dental trauma. Relation to bad oral habits in Isle of Youth was carried out to determine the relation between dental traumas and bad oral habits in children in the 3 to 14 age group. The study was carried out with observation, descriptive and transverse techniques. The statistics was made up of 1630 children and a sample of 520 patients. It was carried out to determine the frequency of dental trauma according to age and to characterize patients who suffer from dental traumas due to bad oral habits CHI (X2) and odds ratio tests were run to determine the level of association. Patients in the 6 to 11 age group were the most affected by traumas with the 14.2 percent. The most frequent bad oral habit associated with dental trauma was digital sucking, fallowed by bottle feeding and oral respiration.

In endotoxic shock, variations are known to occur in different biochemical parameters of oxidative stress. Ozone oxidative preconditioning (OOP) is a good candidate to restore the redox balance on different tissue. This investigation examined the effect of OOP on different biomarkers of oxidative stress in hepatic tissue of mice treated with lipopolysaccharide (LPS). LPS doses of 30 mg/kg were administered intraperitoneally (i.p.) and pretreatment with ozone/oxygen mixture (OOM) was applied i.p. at 0.2, 0.4, and 1.2 mg/kg once daily during 5 days before LPS injection. The mice were euthanized under ether atmosphere at different times, 1 and 24 h after LPS injection. Hepatic tissue from all animals was taken for biochemical determinations of oxidative stress parameters such as thiobarbituric acid reactive substances (TBARS) content and activity of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione S-transferase (GST). The results demonstrated that OOP reduces levels of TBARS content and increases the activity of GPx in hepatic tissue. In conclusion, OOP was able to recover the redox balance and in this way to protect the animals against the oxidative damage induced by endotoxemia.
