ABSTRACT
Dental wear arises from mechanical (attrition or abrasion) and chemical (erosion) factors. Despite its prevalence and clinical significance, accurately measuring and understanding its causes remain challenging in everyday practice. This one-year study with 39 participants involved comprehensive examinations and full-arch intraoral scans at the start and after 12 months. Volume loss exceeding 100 µ on each tooth's surfaces (buccal, lingual/palatine and incisal/occlusal) was measured by comparing three-dimensional scans from both time points. This study also assessed factors such as abrasion and erosion through clinical exams and questionnaires. There were no significant differences in dental wear in participants with sleep bruxism. However, noticeable wear occurred in the front teeth of those with waking bruxism and joint-related symptoms. Increased wear was associated with frequent consumption of acidic drinks, regular swimming, dry mouth, nocturnal drooling and heartburn, while no significant wear was found in patients with reflux. The used methodology proved effective in accurately assessing the progression of dental wear, which is important as many patients may initially be asymptomatic. The variability observed in dental wear patterns underscores the need to develop specific software applications that allow immediate and efficient comparison of wear areas based on extensive analysis of patient databases.
ABSTRACT
El propósito de este trabajo es aplicar la tecnología actual usando los escáneres intraorales para posibilitar un diagnóstico más objetivo del desgaste dental. Se realizó un estudio de evaluación de desgaste sobre 53 alumnos de Odontología, utilizando como medio de registro de ambas arcadas el escáner intraoral True Definition 3M® (ESPE, Seefeld, Germany). Para evaluar el desgaste se utilizó el índice Smith & Knignt aplicándolo a las superficies vestibular, palatina/lingual y oclusal/incisal desde el primer incisivo incisivo a primer molar en ambas arcadas. Los resultados mostraron una mayor superficie de desgaste en el grupo ántero-incisal (superior) por palatino, caninos por incisal, primeros premolares superiores e inferiores por oclusal. Las localizaciones de las superficies de desgaste encontradas en este estudio concuerdan con los datos hallados en la literatura científica. El escáner intraoral se muestra, en las condiciones de este estudio, como una herramienta eficaz en la detección del desgaste dental (AU)
The purpose of this paper is to apply current technology using intraoral scanners to enable a more objective diagnosis of dental wear. An evaluation study on 53 Denstritry students using as a recording medium of both arches intraoral scanner True Definition 3M was performed. To assess the Smith & Knignt wear index was used by applying to, palatal / lingual and occlusal / incisal from the incisor to first molar buccal surfaces. The results showed increased wear surface in the anteriorincisal group (superior) palatal, incisal canines, occlusal upper first premolars and first molars occlusal. The locations of the wear surfaces found in this study are consistent with data found in the scientific literature. The intraoral scanner is shown under the conditions of this study, as an effective tool in the detection of dental wear (AU)

La limpieza del sistema de conductos es una parte clave en el tratamiento endodóntico de tal modo que forma parte de los tres pilares de la endodoncia (junto con la instrumentación y la obturación). El estado actual de la ciencia muestra que la irrigación activa, junto con el uso de productos como los quelantes del calcio, pueden arrojar resultados más predecibles en cuanto a limpieza de los conductos. En este estudio se comparan diferentes formas de irrigación activa confrontando el resultado con la irrigación pasiva, utilizando diferentes patrones de irrigación in Vitroa distintas concentraciones (AU)
