    La edad del paciente ha sido considerada por la mayoría de autores un parámetro esencial en la elección entre expansión ortopédica y expansión rápida del paladar quirúrgicamente asistida (SARPE) para tratar las discrepancias transversales maxilomandibulares. La mayoría de los autores coinciden en que la edad límite para realizar disyunción ortopédica sin necesidad de intervención quirúrgica son los 15 años de edad. Por lo que la opción terapéutica de elección para la corrección de discrepancias transversales depende principalmente de la madurez esqueletal del paciente y de la magnitud de la discrepancia transversal. Según Silverstein et al. las discrepancias transversales maxilomandibulares menores de 5 mm requieren expansión ortodóncica u ortopédica para su correción, sin embargo discrepancias transversales mayores a 5 mm en pacientes con madurez esqueletal requieren de SARPE

    Purpose To evaluate the efectiveness of apexifcation versus revascularization in the treatment of necrotic immature teeth and determine which strategy afords the greatest radiological success rate. Methods An analysis was made of 18 teeth subjected to mineral trioxide aggregate (MTA) apical plugging and regenerative endodontic treatment, assessing healing of the apical lesions and the changes in root dimensions. Results Signifcantly greater root growth was observed with revascularization in terms of the percentage change in length (12.75% at 6 months) and dentin thickness (34.57% at 6 months) (p<0.05). There were no signifcant diferences between the two treatments in terms of the apical healing scores after 6 months of follow-up (p>0.05). Conclusion Apexifcation with an MTA apical plug and pulp regeneration are reliable treatments for non-vital immature teeth. The radiographic outcomes are comparable between the immature teeth subjected to MTA apexifcation versus those subjected to revascularization. The results of the present study indicate a greater increase in root length and width with regenerative endodontic treatment

    Dispositivo de avance máxilo-mandibular en base a anclaje óseo que consta de dos bielas (una por cada lado) ancladas directamente sobre dos miniplacas quirúrgicas (una en el maxilar superior y otra en el maxilar inferior). Este tipo de aparatología en base a un dispositivo intermaxilar fijada y no removible permite principalmente tres ventajas respecto a la ortopedia convencional y la actual en base a anclaje esquelético: 1) su acción directa sobre los huesos maxilares; 2) acción terapéutica durante 24 horas, para conseguir un máximo efecto ortopédico en el menor tiempo posible; 3) no dependencia de la colaboración del paciente (factor de fracaso de mayor frecuencia en la literatura).Españ

    AbstrAct Introduction: the aim is to describe the treatment of three immature permanent incisors associated to apical periodontitis, based on the placement of an apical mineral trioxide aggregate (MtA) plug for apexification. case series: Apexification was carried out by opening the pulp chamber, with debridement of the canal following anesthesia and isolation of the tooth. the canal was filled with pure calcium hydroxide in powder form, dissolved in saline solution for one week, and the aperture was sealed with IrM (Dentsply, Germany). One week later, the calcium hydroxide was removed and an MtA apical plug was positioned, sealing with a humid cotton pellet and IrM (Dentsply, Germany). After setting of the MtA, conventional endodontic treatment was carried out using gutta-percha, with definitive restoration of the tooth. conclusion: All three cases, treated with MtA showed complete apical repair with rounding of the apex at radiographi

    Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI &lt;18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For school&#x2;aged children and adolescents, we report thinness (BMI &lt;2 SD below the median of the WHO growth reference) and obesity (BMI &gt;2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit
