Living and Coping with Olfactory and Taste Disorders: A Qualitative Study of People with Long-COVID-19.

Taste and smell disorders are common symptoms of SARS-CoV-2 acute infection. In post-COVID-19 condition, symptoms can persist leading to disruption in patients' lives, to changes in their coping skills, and to the need to develop strategies for everyday life. This study aimed to describe the perspective of a group of patients with Long-COVID-19, a condition where loss of taste and/or smell was the most predominant symptom.

In-office dental bleaching in adolescents using 6% hydrogen peroxide with and without gingival barrier: a randomized double-blind clinical trial.

Background: At low concentrations used for in-office bleaching gels, such as 6% HP, gingival barrier continues to be performed. If we take into account that, in the at-home bleaching technique, no barrier is indicated, it seems that the use of a gingival barrier fails to make much sense when bleaching gel in low concentration is used for in-office bleaching.

Objective: This double-blind, split-mouth, randomized clinical trial evaluated the gingival irritation (GI) of in-office bleaching using 6% hydrogen peroxide (HP) with and without a gingival barrier in adolescents, as well as color change and the impact of oral condition on quality of life.

In-office dental bleaching in adolescents using 6% hydrogen peroxide with different application tips: randomized clinical trial.

Objective: Despite the availability of in-office bleaching gels with a 6% concentration of hydrogen peroxide (HP), these gels have not been evaluated in younger patients. They are commercially available with a tip, associated or not with a brush, where the tip with a brush spreads the gel over the entire surface to have a smaller thickness (thin layer) since the manufacturers indicate the application of a thin layer of gel. This randomized, split-mouth, double-blind clinical trial evaluated the efficacy of in-office bleaching with 6% HP in adolescents using different application tips, as well tooth sensitivity (TS) and aesthetic self-perception.

Influence of the bracket on bonding and physical behavior of orthodontic resin cements.

The aim of the study is to determine the influence of the type of bracket, on bond strength, microhardness and conversion degree (CD) of four resin orthodontic cements. Micro-tensile bond strength (µTBS) test between the bracket base and the cement was carried out on glass-hour-shaped specimens (n=20). Vickers Hardness Number (VHN) and micro-Raman spectra were recorded in situ under the bracket base.

Influence of cavity type and size of composite restorations on cuspal flexure.

Objectives: The present study examines the influence of cavity type, and size of composite restorations on cuspal flexure due to polymerization shrinkage.

Methods: Thirty healthy premolars were selected and divided into two experimental groups. Group 1: Mesial, mesio-distal, and MOD cavities were successively prepared in each tooth by means of the SONICSYS approx system (KaVo) using a n 2 (small) diamond tip.

The effect of antiretroviral therapy on the prevalence of HIV-associated oral candidiasis in a Spanish cohort.

Objective: To investigate the temporal changes in the prevalence of oral candidiasis in a cohort of Spanish human immunodeficiency virus (HIV)-infected individuals, before and after the introduction of highly active antiretroviral therapy (HAART).

Study Design: Retrospective analysis of a clinical database from "Carlos Haya" Hospital, Málaga, Spain, from 1995 to 2000. The prevalence of oral candidiasis was assessed in 807 HIV/AIDS patients and the temporal progression of its major variants evaluated using a linear regression model.
