Taste disorders in disease
2016
Among the different sensory systems, gustation is one of the most elaborate. In its sensory task, gustation is helped by interactions with other sensory systems (olfaction, vision, audition, and somatosensory, trigeminal and thermal sensations). It allows the detection and identification of soluble compounds which can be ingested or must be avoided. This function is fundamental to ingestive behavior (energy intake and selection of nutrients) in order to meet physiological needs. Taste is also fundamental to the genesis of hedonic sensations and, therefore, the desire to eat (appetite). The tasting step is also the first stage of the digestion, absorption, and storage of nutrients due to ant…
Oral manifestations in SARS-CoV-2 infection
2022
We aimed to evaluate the prevalence of predisposing factors and oral manifestations in SARS-CoV-2 infection. 204 SARS-CoV-2 positive patients were included in the study. Questions regarding the systemic, periodontal health, oral hygiene habits, common symptoms and, oral manifestations of COVID-19 such as oral lesions, and dry mouth were included in the survey. The Visual Analogue Scale (VAS) was used. 47.5% of individuals had various systemic diseases. Dry mouth (44.2%) and oral lesions (22.4%) were the most common oral manifestations in COVID-19 patients. Also, dry mouth had the highest VAS score. The most common oral lesion locations were buccal mucosa (15.2%) and tongue (10.8%). The majo…
Bilateral taste disorders in patients with Ramsay Hunt syndrome and Bell palsy
2018
OBJECTIVE Ramsay Hunt syndrome (RHS) and Bell palsy (BP) are typically known as facial nerve motor syndromes and are primarily unilateral. The aim of this study was to challenge this assertion, because both conditions are also known to be associated with viruses that typically affect several nerves. METHODS Ten participants with RHS, 12 with BP, all clinically unilateral, and 12 healthy controls were prospectively enrolled. Electrogustometric thresholds were measured bilaterally in the areas of the chorda tympani, the glossopharyngeal, and the major petrosal nerve. Also bilaterally, the taste function was tested using chemogustometry with different tastant concentrations. Again bilaterally,…
Sensibility and taste alterations after impacted lower third molar extractions. A prospective cohort study
2012
Objectives: To determine the incidence, severity and duration of lingual tactile and gustatory function impairments after lower third molar removal. Study Design: Prospective cohort study with intra-subject measures of 16 patients undergoing lower third molar extractions. Sensibility and gustatory functions were evaluated in each subject preoperatively, one week and one month after the extraction, using Semmes-Weinstein monofilaments and 5 different concentrations of NaCl, respectively. Additionally, all patients filled a questionnaire to assess subjective perceptions. Results: Although patients did not perceive any sensibility impairments, a statistically significant decrease was detected …

Differences in the Density of Fungiform Papillae and Composition of Saliva in Patients With Taste Disorders Compared to Healthy Controls
2017
International audience; This study investigated the relation of the fungiform taste papillae density and saliva composition with the taste perception of patients suffering from diagnosed taste disorders. For this purpose, 81 patients and 40 healthy subjects were included. Taste was measured by means of regional and whole mouth chemosensory tests, and electrogustometry. Olfaction was assessed using the Sniffin Sticks. Fungiform papillae were quantified using the "Denver Papillae Protocol for Objective Analysis of Fungiform Papillae". In addition, salivary parameters [flow rate, total proteins, catalase, total anti-oxidative capacity (TAC), carbonic anhydrase VI (caVI), and pH] were determine…
An Online Observational Study of Patients With Olfactory and Gustory Alterations Secondary to SARS-CoV-2 Infection
2020
Introduction: Since the beginning of the Covid-19 epidemic produced by SARS2-Cov virus, olfactory alterations have been observed at a greater frequency than in other coronavirus epidemics. While olfactory alterations may be observed in patients with rhinovirus, influenza virus, or parainfluenza virus infection, they are typically explained by nasal obstruction with mucus or direct epithelial damage; in the case of SARS-CoV-2, olfactory alterations may present without nasal congestion with mucus. We performed a study of patients presenting olfactory/gustatory alterations in the context of SARS-CoV-2 infection in order to contribute to the understanding of this phenomenon. Material and Method…
The Effects of an Essential Oil and an Amine Fluoride/Stannous Fluoride Mouthrinse on Supragingival Plaque Regrowth
2008
Background: The side effects of chlorhexidine (CHX) have stimulated the search for alternative antiplaque agents such as amine fluoride/stannous fluoride (ASF) and essential oils (EO). The aim of the study was to investigate the plaqueinhibiting effects of two commercially available mouthrinses containing ASF and EO, respectively. Methods: The study was an observer-masked, randomized, 5 · 5 Latin square cross-over design, balanced for carryover effects, involving 15 volunteers in a 4-day plaque regrowth model. A 0.12% CHX rinse and a saline solution served as positive and negative controls, respectively. On day 1, subjects received professional prophylaxis, suspended oral hygiene measures, …
Oral complaints in patients with acute myeloid leukemia treated with allogeneic hematopoietic stem cell transplantation
2021
Background Acute myeloid leukemia belongs to proliferative diseases of the hematopoietic system. It is currently the leading indication for allogeneic hematopoietic stem cell transplantation. This study was designed to determine the most common subjective oral mucosa complaints in patients with acute myeloid leukemia after allogeneic hematopoietic cell transplantation, in relation to the type of conditioning used. Material and Methods Eighty patients diagnosed with acute myeloid leukemia were assigned to two groups depending on the intensity of the conditioning regimen before transplantation: myeloablative and reduced-intensity chemotherapy. The oral symptoms were evaluated based on an auth…
Evaluation of the xerostomia, taste and smell impairments after Covid-19
2021
Background The purpose of this study was to explore the effects of coronavirus disease 19 (Covid-19) on the oral cavity by evaluating the oral findings in the patients who recovered after treatment. Material and Methods This study involved confirmed Covid-19 patients whose treatment completed at least two weeks ago. A questionnaire consist of eight parts was applied to explore the oral findings after Covid-19. Also stimulated salivary flow rate was evaluated with a salivary flow test. Results 177 patients reached and 107 of them participate in the study. Regarding gender significant differences were found in terms of the presence of taste impairment after treatment (p=0.007), the degree of …
