Abstract Background: Public health problems associated with oral disease affect large numbers of people in countries around the world. Dental caries continues to be the main cause of premature tooth loss in patients and can negatively affect the Quality of life (QoL) related to oral health for both the individual and their family. Depending on their stage of advancement of caries, a restorative procedure is required, since caries injuries generally involve changing the shape, function or esthetics, restoring is intended to extend the life of the teeth, The purpose of this study was evaluated direct restorations on posterior teeth with conventional and bulk-fill composite resins performed by public health professionals and their effect on Quality of life. Methods: The sample consisted of 100 teeth in 50 patients. The teeth selected for the restorative procedure were randomized in the two study groups according to restorative material. Group 1 - Bulk fill composite resin, or Group 2 - Conventional composite resin. At the end of 12 and 24 months, the restorations were evaluated according to USPHS criteria, by two evaluators. To evaluate the Quality of Life related to oral health, Oral Health Impact Profile – 14 (OHIP-14) was used before and after restorative treatment (12 months). Results: After 12 months, 90 restorations were evaluated that showed no statistical difference (p> 0.05), after 24 months, 80 restorations evaluated and also showed similar clinical performance and no statistical difference (p> 0.05). The analysis of quality of life detected a statistical difference only in the psychological discomfort domain (p = 0.024), improving their values at the end of the treatment. There are no differences between the clinical performance with conventional resins or bulk-fill system. Restorative treatment improved the perception of concern and stress suffered by patients by dental problems. Clinical Trial Registry: RBR-7hbmjp

"Introducción: Durante la realización de prótesis fijas, el paciente puede presentar sensibilidad posoperatoria. Se ha descrito en la literatura diferentes prevalencias de esta sensibilidad, las cuales varían ampliamente, entre 3 % y 34 %. Objetivo: Determinar la prevalencia e intensidad de sensibilidad posoperatoria en el tratamiento de prótesis fija sobre diente vital. Métodos: se realizó un estudio clínico piloto descriptivo. La muestra fue de 35 dientes tratados de 20 pacientes. Esta fue conformada por pacientes atendidos por alumnos del Centro Odontológico de la Universidad de Los Andes, a los cuales se les realizó un tratamiento en base a prótesis fija sobre diente vital, desde el mes de abril hasta octubre del año 2015. Se registró la sensibilidad durante el tratamiento por medio la escala visual análoga a través de un diario completado por el paciente y por la escala verbal numérica aplicada por el investigador en distintas etapas clínicas. Resultados: Se observó una prevalencia del 31,4 % con una intensidad de 0,62 ± 0,49 según la escala visual análoga y de 0 según la escala verbal numérica. Conclusiones: la prevalencia de la sensibilidad posoperatoria se aproximó al rango más alto descrito en la literatura. La intensidad de la sensibilidad observada fue leve a imperceptible clínicamente."
The change of teeth color, whiteness variations and its psychosocial and self-perception effects when using low vs. high concentration bleaching gels: a one-year follow-up.

<title>Abstract</title> Background: Dental bleaching in traditional concentrations generates greater sensitivity. In this respect, new systems of lower concentration of hydrogen peroxide for tooth bleaching appeared, with color stability unknown over time. The aim of this study was to compare the change and stability of color with low-concentration (6%) hydrogen peroxide gel in an in-office bleaching setting relative to conventional 37.5% gel, including their effects on psychosocial and esthetic self-perception, after one year. Methods: Patients (n=25) were assessed at 12 months post bleaching treatment (whitening with 6% chemo-activated alkaline formula gel versus 37.5% traditional concentration gel). Color changes were measured objectively using total variation in color (ΔE), and subjectively using Vita Classical and Vita Bleached scale (ΔSGU) by calibrated evaluators (Kappa=0.85). The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and Oral Health Impact Profile (OHIP-14) aesthetic questionnaires were used to measure the self-perception and the psychosocial impact of the bleaching protocols. Results: The effect (ΔE) of 37.5% HP (8.37 ± 2.73) was significantly better than that of 6% HP (5.27 ± 2.53) in terms of color rebound after one year of follow-up. There were significant differences in psychosocial impact and esthetic self-perception measurements prior to bleaching versus one-year post-whitening time points; positive effects were maintained. Conclusions: Low concentration (6%) achieved effective bleaching with good stability after one year, accompanied by a positive psychosocial impact and enhanced self-perception at follow-up. Trial registration: NCT03217994 (before enrollment of the first participant). Data register: July 14, 2017
