Comparación del ángulo de la guía condílea sagital obtenida del registro radiográfico y clínico en pacientes dentados / Comparison of sagittal condylar guidance obtained from radiographic and and clinical records in dentate patients

Objetivo: Comparar el ángulo de la guía condílea sagital obtenida del registro radiográfico y clínico en pacientes dentados. Materiales y métodos: La muestra estuvo conformada por un grupo único de estudio de 32 pacientes, en el que se evaluó la radiografía lateral estricta y los registros posicionales: en relación céntrica, registro protrusivo a 5 mm en lateralidad derecha y registro protrusivo a 5 mm en lateralidad izquierda. Con el registro posicional del arco facial se articuló el modelo superior, con el registro posicional en relación céntrica se articuló el modelo inferior, con los registros laterales protrusivos de los lados derecho e izquierdo se obtuvo la medida del ángulo de la guía condílea sagital para la programación del articulador semiajustable. El plan estadístico en la presente investigación utilizó el programa SPSS versión 24, la normalidad fue evaluada usando el test de Shapiro-Wilk, también se realizaron las pruebas de T de Student y correlación de Pearson. Resultados: Se determinó estadísticamente que el género y la edad influyen en la medida del ángulo de la guía condílea sagital. El método radiográfico presentó un ángulo de guía condílea de 35,69 ±5,18 y con el método clínico fue 35,69 ± 5,16 (p > 0,05). La prueba de correlación de Pearson sí mostró una correlación importante entre ambos métodos r = 0,948, p < 0,001. Conclusiones: Existe alta correlación en las medidas obtenidas del ángulo de la guía condílea sagital con los registros radiográficos y clínicos; esta concordancia permitiría reemplazar un método por el otro.

Objective: To compare the angle of the sagittal condylar guidance obtained from the radiographic and clinical records of dentate patients. Materials and Methods: The sample consisted of 32 patients in whom strict lateral radiography and positional records were performed: in centric relation, protrusive recording 5 mm in right laterality and protrusive recording 5 mm in left laterality. With the positional registration of the facebow, the upper model was articulated, while the lower model was articulated with the positional registration in centric relation, and with the protrusive lateral registrations on the right and left side the condylar guidance was obtained for programming the semi-adjustable articulator. Statistics were performed with the SPSS program version 24 in Spanish. Normality was evaluated using the Shapiro-Wilk test, for data with normal distribution, and the Student's T test and Pearson's correlation were performed in descriptive statistics. Results: The statistical analyses showed that gender and age influence the angle measurement of the sagittal condylar guide. The radiographic method presented a condylar guide angle of 35.69 ± 5.18, being 35.69 ± 5.16 with the clinical method (p> 0.05). Pearson's correlation test showed an important correlation between the two methods (r = 0.948, p <0.001). Conclusions: There is a high correlation in the measurements obtained from the angle of the sagittal condylar guide and the radiographic and clinical records, indicating that both methods are effective.

An updated review of idiopathic osteosclerosis of the jaws / Una revisión actualizada de la osteoesclerosis idiopática en los maxilares

Objective: The aim of this study was to update the concepts of the diagnosis of idiopathic osteosclerosis (IO) of the jaws by digital panoramic radiographs and cone beam tomography and describe the impact of this disease on oral and general health. Methods: A search of the main databases of dental medical research was carried out using the search terms "osteosclerosis, panoramic radiography, cone beam computed tomography, jaws". Articles without language restriction until September 30, 2020 were identified. The prevalence and clinical and radiographic characteristics of IO of the jaws were examined in 2D and 3D imaging studies, as well as the interaction during treatments in the various dental specialties. Results: We analyzed the current situation regarding the diagnosis of IO, with an update of the diagnostic criteria used to accurately identify IO in the latest generation imaging studies, as well determine its possible interactions in oral an general health. Conclusions: It is important to have a clear differential diagnosis of IO and be able to distinguish different radiopacities in the maxilla. Accurate reporting and monitoring of the morphometric characteristics are necessary taking into account the impact the presence of IO of the jaws has on future dental treatments. (AU)

Objetivo: El propósito de esta investigación fue actualizar las consideraciones para el diagnóstico de la osteoesclerosis idiopática en radiografías panorámicas digitales y tomografías de haz cónico, a fin de determinar sus implicancias en la salud oral y general. Métodos: Se realizó las pesquisas en las principales bases de datos de investigación médica estomatológica, utilizando las palabras "osteoesclerosis", "radiografía panorámica", "tomografía computarizada de haz cónico" y "mandíbula". Se identificaron artículos sin restricción de idioma, desde las primeras publicaciones hasta el 30 de septiembre del 2020. Se examinaron la prevalencia, las características clínicas y radiográficas en estudios imagenológicos de dos y tres dimensiones, así como su interacción durante los tratamientos realizados en las diversas especialidades estomatológicas. Resultados: La información obtenida nos permitió analizar la situación actual con respecto al diagnóstico de la OI y actualizar los criterios diagnósticos para una identificación certera de la OI en los estudios imagenológicos de última generación, así como sus posibles interacciones en la salud oral y general. Conclusiones: Es importante tener un criterio diagnóstico diferencial claro al distinguir las diferentes radiopacidades como la OI, que se pueden presentar en los maxilares, mediante un registro preciso de sus características morfométricas y seguimiento en el tiempo, teniendo en cuenta su existencia y sus implicancias en los tratamientos dentales a futuro.

[Prevalence of idiopathic osteosclerosis in patients cared for at a radiological center in Ayacucho from 2016-2018]. / Prevalencia de osteoesclerosis idiopática de pacientes atendidos en un centro radiológico de Ayacucho entre los años 2016 y 2018.

Objective: The objective of this study was to determine, describe and identify the prevalence of radiopaque images compatible with idiopathic osteosclerosis in digital panoramic radiographs taken in patients between the ages of 18 and 50. Materials and methods: The study design was descriptive, cross-sectional and retrospective. The sample consisted of 500 digital panoramic radiographs taken between January 1, 2016 and December 31, 2018, in the target population aged between 18 and 50 years from Ayacucho - Peru, attended at a private radiological center. The radiographs obtained were analyzed using the Romexis viewer version 5.3 program, and the results were recorded on a data collection sheet. The Chi-square test was used to establish associations among the variables evaluated. A P <0.05 was considered significant. Results: 500 digital panoramic radiographs were analyzed, showing a prevalence of idiopathic osteosclerosis of 17.4%, of which 12% were female and 5.4% male, and according to age, the presence of idiopathic osteosclerosis was more prevalent in the second decade of life. Conclusions: It is important to have a clear differential diagnostic criterion when distinguishing the different radiopacities such as idiopathic osteosclerosis, which can occur in the jaws, making a precise record of the morphometric characteristics and monitoring over time, taking into account their existence and implication in dental treatments.
