Chitosan for the treatment of inflammationof the oral mucosa: A systematic review / Chitosán para el tratamiento de la inflamación de la mucosa oral: una revisión sistemática

Background: Chitosan is a cheap, accessible, nontoxic, biocompatible, and biodegradable compound. Also, thispolysaccharide possesses antibacterial and anti-inflammatory properties. Consequently, a wide range of chitosanapplications in the dentistry field has been explored. This work aimed to conduct a systematic review to addressthe clinical efficacy of chitosan for the treatment of oral mucositis.Material and Methods: The design of the included studies were observational studies, randomized clinical trials(RCT), and non-randomized clinical trials (non-RCT), whereas, a series of cases, in vivo, and in vitro studies wereexcluded. The search was performed in PubMed, Web of Science, Scopus, Dentistry and Oral Sciences Source,and ClinicalTrials. Gray literature was searched at Google Scholar. Relevant data from all included studies wererecorded. The risk of bias (using RoB 2) and the quality (using Grading of Recommendations Assessment, Devel-opment, and Evaluation, GRADE) assessments were carried out.Results: From the 8413 records screened, 5 clinical trials fully met the eligibility criteria, which comprised a totalof 192 participants suffering oral lesions and pain related to oral mucositis. 100% of the included studies exhibiteda high risk of bias. The quality of the studies was between low and very low.Conclusions: The results of the included studies suggest that chitosan can diminish pain and improve the healingof ulcers in oral mucositis. However, there is no conclusive evidence of chitosan as a superior treatment for oralmucositis compared with other current therapies.(AU)

The use of E-cigarettes as a risk factor for oral potentially malignant disorders and oral cancer: a rapid review of clinical evidence / El uso de cigarrillos electrónicos como factor de riesgo de trastornos orales potencialmente malignos y cáncer oral: una revisión rápida de la evidencia clínica

Background: The popularity of e-cigarettes has increased rapidly in the last decade, particularly among teens andyoung adults, being advertised as a less harmful alternative to conventional tobacco products. However, in vitroand in vivo studies have evidenced a variable quantity of potentially harmful components and some recognizedcarcinogens which may cause DNA damage in oral cells. Additionally, evidence suggests that e-cigarettes mayplay active roles in the pathogenesis of other malignancies, such as lung and bladder cancers. Therefore, this rapidreview aimed to assess the available clinical evidence about using e-cigarettes as a risk factor for oral potentiallymalignant disorders (OPMD) and oral cancer.Material and Methods: A systematic search for English language articles published was performed in PubMed(MEDLINE), Embase, Scopus, and Web of Science. After the study selection process, the authors included twelveclinical studies about OPMD and oral cancer risk in e-cigarette users.Results: The main findings showed the presence of carcinogenic compounds in saliva and morphologic changes,DNA damage, and molecular pathways related to carcinogenesis in the oral cells of e-cigarette users. However,results were inconsistent compared to tobacco smokers and control groups.Conclusions: the current clinical evidence on this topic is limited and insufficient to support using e-cigarettes asa risk factor for OPMD and oral cancer. Nevertheless, dental care professionals should advise patients responsiblyabout the potentially harmful effects of e-cigarettes on the oral mucosa cells. Future long-term and well-designedclinical studies are needed.(AU)

Medication impact on oral health in schizophrenia / Impacto de los medicamentos en la salud bucal en la esquizofrenia

Background: Patients with schizophrenia constitute a particularly vulnerable group for oral diseases. Among thedifferent factors involved, we aimed to examine the evidence of how drugs could contribute to the poorer oralhealth of this population.Material and Methods: An overview of the potential impact of medication on dental/oral health among people withschizophrenia was proposed focusing on selected literature.Results: Studies show a higher dental caries and degree of periodontal diseases in this population and point todrug-induced xerostomia as an important risk factor for oral health deterioration. The risk of dry mouth dependson not only antipsychotics, but also drugs with anticholinergic activity. We hypothesize that antipsychotic inducedglycaemic alterations might contribute to reduced oral health, and that the antimicrobial activity of certain an-tipsychotics could have an impact on oral microbiota affecting oral condition. Pharmacovigilance data show thatinvoluntary movements are caused by typical and some atypical antipsychotics. Dry mouth is most frequentlyreported for quetiapine and olanzapine, while clozapine is more frequently associated with sialorrhea.Conclusions: Literature clearly shows higher caries and periodontal disease in schizophrenic patients. However,overall, there is scarce literature about the potential influence of drugs in these disorders. Health professionalsshould be aware of this issue in order to implement adequate preventive measures in this vulnerable population.(AU)

Proliferative verrucous leukoplakia/multifocal leukoplakia in patients with and without oral submucous fibrosis / Leucoplasia verrugosa proliferativa/leucoplasia multifocalen pacientes con y sin fibrosis submucosa oral

Background: Oral submucous fibrosis (OSF) and proliferative verrucous leukoplakia (PVL) are established as oralpotentially malignant disorders. Dual pathology of the two conditions is not commonly encountered in clinicalpractice. This study aims to present a case series of multifocal leukoplakia in patients with and without OSF tooutline the clinical behavior and challenges in the management of this high-risk group in clinical practice.Material and Methods: We retrospectively analyzed cases of six Indian patients (four with OSF) managed over aperiod of 5.5 to 13 years at the Government Dental College, Nagpur. Patient data consisting of age, gender, med-ical history, habits, clinical findings, and biopsy reports were recorded at the initial visit. During follow-up visits,the clinicopathological data were reassessed. When surgical intervention failed to arrest the disease or whensurgery was contraindicated metronomic therapy with Folitrax 15 mg once a week and Celecoxib 100mg twicedaily was initiated.Results: All patients developed PVL after the initial pathology diagnosis of OSF or oral leukoplakia. Initial lesionswere either homogenous or non-homogenous leukoplakia. All patients developed multiple recurrences, regional orsystemic metastasis. Despite thorough interventions, the patients died of, or with the disease.Conclusions: The occurrence of two or more oral potentially malignant disorders poses challenges in patient man-agement and possibly presents a higher risk of malignant transformation. More clinical trials are necessary to as-sess the benefits of metronomic therapy for patients diagnosed with aggressive PVL concurrently found with OSF.(AU)

Comparison of the recurrence rate of different surgical techniques for oral mucocele: A systematic review and Meta-Analysis

Background: There are different surgical techniques to remove Oral mucoceles, including conventional surgery with scalpel, removal of the lesion with CO2 laser, and micro marsupialization. The present systematic review was conducted with the aim of comparing the recurrence rate of different surgical techniques for treatment of the oral mucoceles. Material and Methods: An electronic search for randomized controlled trials published in English until September 2022 related to different surgical methods for the treatment of oral mucocele was performed in Medline/PubMed, Web of Science, Scopus, Embase and Cochrane databases. A random-effects meta-analysis was conducted to compare the recurrence rate of different techniques. Results: Among 1204 papers initially identified, after the removal of duplicate articles and screening of the titles and abstracts, fourteen full-text articles were reviewed. Seven articles comparing the recurrence rate of oral mucocele in different surgical techniques were found. Seven studies were included in qualitative studies, and five articles were included in the meta-analysis. The risk of mucocele recurrence in the micro-marsupialization technique was 1.30 times that of the surgical excision with scalpel technique, which was not statistically significant. The risk of mucocele recurrence in the CO2 Laser Vaporization technique was 0.60 times that of the Surgical Excision with Scalpel technique, which was not statistically significant. Conclusions: The results of this systematic review showed that there is no significant difference between the recurrence rate of surgical excision, CO2 laser and marsupialization techniques for the treatment of oral mucoceles. Although more randomized clinical trials are needed for definitive results. (AU)

Oral amyloidosis: an update

Background: Amyloidosis is a disease characterized by the progressive deposition of abnormal proteins that can occur in any organ. In the oral cavity, the tongue is the most common affected site, usually causing macroglossia. Biopsy is essential for the diagnosis and the occurrence of its systemic form is mandatory to be investigated. This systematic review evaluated the existing information in the literature on Amyloidosis in the oral cavity to allow a more comprehensive and updated analysis of its clinicopathological characteristics, as well as to explore the main forms of treatment and prognostic factors. Material and methods: Electronic searches were undertaken in five databases supplemented by manual scrutiny. Results: A total of 111 studies were included with 158 individuals. Conclusions: The disease had a higher prevalence in women, the tongue was the most affected site, as well as the systemic form of the disease. The worst prognosis was for cases of systemic amyloidosis associated with multiple myeloma. (AU)

Knowledge of diagnosis and management of selected oral mucosal lesions among dentists in The Netherlands

Background: Knowledge of oral mucosal lesions (OMLs) among dentists is relevant in diagnosing potentially malignant diseases and oral cancer at an early stage. The aim of this survey was to explore dentists' knowledge about OMLs. Material and methods: Respondents to a web-based questionnaire, containing 11 clinical vignettes representing patients with various OMLs, provided a (differential) diagnosis and management for each. Information about demographics and clinical experience of the participants was acquired as well. Descriptive statistics were performed and T-tests were used to test for significant (p<0.05) differences in mean scores for correct diagnosis and management between subgroups based on demographic variables. Results: Forty-four of 500 invited dentists completed the questionnaire. For (potentially) malignant OMLs, the number of correct diagnoses ranged from 14 to 93%, whilst the number of correct management decisions ranged from 43 to 86%. For benign OMLs, the number of correct diagnoses and management decisions ranged from 32 to 100% and 9 to 48%, respectively. For 11 clinical vignettes, mean scores for correct diagnosis, correct management and correct diagnosis and management were respectively 7.2 (±1.8), 5.7 (±1.5), and 3.8 (±1.7). Conclusions: The results show that dentists in the Netherlands do not have sufficient knowledge to accurately diagnose some OMLs and to select a correct management. This may result in over-referral of benign OMLs and under-referral for (potentially) malignant OMLs. Clinical guidelines, that include standardized criteria for referral, and continuing education, may improve dentists' ability to correctly diagnose and accurately manage OMLs. (AU)

Clinical characteristics of oral chronic graft-versus-host disease according to the 2014 National Institutes of Health (USA) consensus criteria

Background: Chronic graft-versus-host disease (cGVHD) is a serious and common complication of allogeneic hematopoietic cell transplantation (alloHCT). The oral cavity is the second most common site affected by cGVHD. In 2014, the 2005 National Institutes of Health (NIH) consensus criteria were revised to address areas of controversy. The aim of this study was to evaluate the clinical characteristics of oral cGVHD using the 2014 NIH consensus criteria. Material and methods: The baseline data of oral manifestation of patients, who were diagnosed with oral cGVHD, in the first dental visit were analyzed (n=22). The oral mucosal disease was evaluated by NIH modified Oral Mucosa Rating Scale (OMRS) and Thongprasom sign score. The salivary gland disease and sclerotic disease were determined by the presence of signs and symptoms. The functional impact was assessed by the organ-specific severity score. Results: The median time from transplant to oral cGVHD diagnosis was 11.9 months. White striae with an erosive area was found in 72.7% of the patients. The mean ± SD of NIH modified OMRS was 6.1 ± 3.0. The most common and severely affected site of lichen planus-like features was buccal mucosa. Xerostomia, superficial mucocele and limited mouth opening were found in 18.2%, 9.1%, and 9.1%, respectively, of the patients. Almost all patients (90.9%) had partial limitation of oral intake. There were no significant differences in NIH modified OMRS or organ-specific severity score among the patient characteristic groups. Moreover, there was no association between the oral manifestations of cGVHD and the patient characteristics. Conclusions: The most common oral manifestation of cGVHD was white striae with an erosive area of oral mucosal disease, followed by xerostomia, superficial mucocele, and limited mouth opening. The 2014 NIH consensus criteria for diagnostic and severity assessment are informative and feasible in real-world practice. (AU)

Manifestaciones bucales en cuidados paliativos: importancia, estrategias terapéuticas y su eficacia / Oral manifestations in palliative care: importance, therapeutic strategies and their effectiveness

Introducción y objetivo: En los cuidados paliativos, las afecciones de la boca son muy frecuentes e interfieren con la calidad de vida del paciente. La boca es un lugar que aún merece poca atención por parte de los profesionales de la salud. El objetivo del presente estudio es caracterizar los trastornos bucales en pacientes de cuidados paliativos, investigar estrategias farmacológicas y no farmacológicas y analizar su eficacia. Material y métodos: Estudio exploratorio, observacional y correlacional sobre trastornos bucales en pacientes hospitalizados en un servicio de cuidados paliativos en Portugal, entre el 6 de noviembre de 2019 y el 31 de julio de 2020. El instrumento de recolección de datos incluyó un cuestionario y consulta del expediente clínico de los enfermos. Resultados: En este estudio (n = 46), el grupo de edad más representativo fue el de 71-90 años (56,52 %). La mayoría presentaba enfermedad oncológica (84,78 %) y estaban polimedicados. De estos, el 95,65 % presentaba dentición incompleta, y el 41,30 % asumía que rara vez realizaba cuidados de higiene bucal. La xerostomía fue reportada por el 89,13 % de la muestra, se observó candidiasis bucal en el 76,09 %, lengua saburral en el 23,91 % y mucositis bucal en el 10,87 %. Los pacientes con patología oncológica están más predispuestos a las alteraciones bucales (p = 0,047) en comparación con los pacientes no oncológicos. Los pacientes con hábitos de higiene bucal frecuentes tienen menos trastornos bucales (rS = –0,54; p = 0,028). Hubo una mejora considerable en la lengua saburral con el aumento en la frecuencia del cuidado de la higiene bucal (p = 0,004). Conclusiones: La implementación de estrategias farmacológicas y no farmacológicas desempeña un papel central en el bienestar y calidad de vida de la persona. Es fundamental que los profesionales de la salud conozcan las afecciones bucales y sus síntomas, lo cual es fundamental para la promoción de su bienestar. (AU)

Introduction and objectives: In palliative care, there are many mouth disorders that arise, interfering with the patient’s quality of life. The mouth is a place that still deserves little attention by health professionals. The present study aimed to characterize mouth disorders in palliative care patients; to identify the etiology of mouth disorders; to investigate pharmacological and non-pharmacological strategies, and to analyse its efficacy. Materials and methods: an exploratory, observational and correlational study on the mouth disorders of patients hospitalized in a palliative care service in Portugal between November 6, 2019 and July 31, 2020. The data collection instrument included a questionnaire and the consultation of the patient’s clinical file. Results: In this study (n = 46), the most representative age group was from 71 to 90 years (56.52 %). Most of them had oncological disease (84.78 %) and were polymedicated. Of these, 95.65 % had incomplete dentition and 41.30 % rarely performed oral hygiene care. Xerostomia was reported by 89.13 % of the sample; oral candidiasis was found in 76.09 %; tongue coating in 23.91 %, and oral mucositis in 10.87 %. Patients with oncological pathology were more predisposed to mouth disorders (p = 0.047) when compared to non-cancer patients. Patients with frequent oral hygiene habits had fewer mouth disorders (rS = –0.54; p = 0.028). There was considerable improvement in tongue coating with increased frequency of oral hygiene care (p = 0.004). Conclusions: The implementation of pharmacological and non-pharmacological strategies plays a central role in patient comfort and quality of life. It is essential that health professionals are aware of mouth conditions and their symptoms, this being essential for the promotion of well-being. (AU)

Una aproximación al coste presupuestario de universalizar la salud bucodental en España / Approximation to the budgetary cost of universalizing oral health in Spain

Objetivo: Realizar una aproximación a una estimación de la repercusión que tendría sobre el gasto público sanitario una ampliación de la cartera de prestaciones en salud bucodental que cubriera la mayor parte de los tratamientos terapéuticos que sufragan actualmente las personas de forma privada. Método: La estimación parte del nivel de gasto en servicios odontológicos del Sistema de Cuentas de Salud del año 2020 y se asume el dato de incremento de la demanda ante la universalización de los servicios extraído de un estudio de RAND para realizar, seguidamente, diversas proyecciones lineales de incremento del gasto introduciendo varios supuestos de copagos lineales para explorar el impacto de distintos mecanismos mixtos de financiación. Resultados: El incremento de la demanda sería de un 47,54% con respecto al gasto actual, y bajo los supuestos de partida el incremento en el gasto público alcanzaría unos 5345 millones de euros. Los diversos escenarios de copago minoran su impacto presupuestario. Conclusiones: A pesar de la mejora de la salud bucodental de la población española, persisten problemas derivados de la existencia de un gradiente socioeconómico que concentra la presencia y la prevalencia de enfermedades en los niveles socioeconómicos más bajos. Ampliar los servicios de la cartera bucodental para cubrir las necesidades de toda la población elevaría el gasto sanitario público en 0,48 puntos sobre el producto interior bruto, y aun así el gasto sanitario público español seguiría por debajo de la media de la Unión Europea. (AU)

Objective: To make an approximation to an estimate of the impact that an increase in the portfolio of oral health benefits would have on public health spending, which would at least cover most of the therapeutic treatments that households currently pay for privately. Method: This estimate is based on the level of expenditure on dental services of the Health Accounts System for the year 2020. The data of increased demand is extracted from a RAND's study on universalization of services. Then we carry out various linear projections of increased spending by introducing several linear co-payment assumptions to explore the impact of different mixed financing mechanisms. Results: The increase in the demand for treatment would be 47.54% with respect to the current level of spending and that, under the starting assumptions, the increase in public spending would reach some 5345 million euros. Various co-pay scenarios could reduce budget impact. Conclusions: Despite the improvement in the oral health of the Spanish population, there are still problems derived from the existence of a socioeconomic gradient that promotes the concentration of the presence and prevalence of diseases in the lowest socioeconomic levels. Extending the services of the oral-dental portfolio to attend to the entire population would increase public health spending by 0.48 points over GDP and, even so, Spanish public health spending would continue to be below the EU-27 average.

Manifestaciones orales en pacientes con psoriasis. Prevalencia y asociación con sus características clínicas y epidemiológicas / Oral Lesions in Patients With Psoriasis: Prevalence and Association With Its Clinical and Epidemiological Characteristics

Antecedentes y objetivo: La psoriasis es una enfermedad con una gran implicación sistémica en la que se ha descrito una mayor prevalencia de alteraciones de la mucosa oral. El objetivo del estudio fue determinar la prevalencia de alteraciones orales en pacientes con psoriasis y su asociación con las características clínicas y epidemiológicas de la enfermedad. Material y métodos: Se realizó un estudio transversal, incluyendo pacientes con psoriasis y voluntarios sanos entre diciembre de 2019 y febrero de 2020. Se recogieron datos biométricos, comorbilidades asociadas y alteraciones orales detectadas en la exploración física. Además, en los pacientes con psoriasis se registraron las características clínicas de la enfermedad. Resultados: Se incluyeron 100 pacientes con psoriasis y 100 controles. Los pacientes con psoriasis presentaron una mayor prevalencia de alteraciones de la mucosa oral respecto al grupo control (74% frente a 46%, p<0,001), destacando una mayor prevalencia de lengua fisurada (LF) (39% frente a 16%, p<0,001) y periodontitis (28% frente a 16%, p=0,04). La lengua geográfica resultó poco frecuente en ambos grupos (4% frente a 2%, p=0,68). Dentro del grupo con psoriasis, los pacientes con LF presentaron mayor prevalencia de enfermedad cardiovascular (23,1% frente a 4,9%), diabetes mellitus (28,2% frente a 8,2%) y artritis psoriásica (15,4% frente a 1,6%) que aquellos sin LF. Los pacientes con periodontitis presentaron también mayor frecuencia de enfermedad cardiovascular (28,6% frente a 5,6%). La forma, la localización y el tiempo de evolución de la psoriasis no se relacionaron con más alteraciones orales. Sin embargo, los pacientes con alteraciones orales presentaron valores medios de la escala PASI (índice de severidad del área de psoriasis) más elevados (3,9 frente a 2,4, p=0,05). Los pacientes con LF presentaron un PASI más elevado que aquellos sin LF (4,7 frente a 2,7, p=0,03) (AU)

Background and objective: Psoriasis is a multisystem disease associated with an increased prevalence of oral lesions. The aim of this study was to determine the prevalence of oral lesions in patients with psoriasis and examine associations with clinical and patient characteristics. Material and methods: We conducted a cross-sectional study of patients with psoriasis and healthy controls seen between December 2019 and February 2020. We recorded biometric data, comorbidities associated with psoriasis, oral examination findings, and clinical characteristics of psoriasis. Results: We studied 100 patients with psoriasis and 100 controls. Oral lesions were more common in the psoriasis group (74% vs 46%, P<.001). The most common lesions were fissured tongue (39% vs 16%, P<.001) and periodontitis (28% vs 16%, P=.04). Geographic tongue was uncommon in both the study and the control group (4% vs 2%, P=.68). In the psoriasis group, patients with fissured tongue had a higher prevalence of cardiovascular disease (23.1% vs 4.9%), diabetes mellitus (28.2% vs 8.2%), and psoriatic arthritis (15.4% vs 1.6%) than those without this condition. Periodontitis was also associated with a higher prevalence of cardiovascular disease (28.6% vs 5.6%). Type of psoriasis, location, and time since onset were not significantly associated with oral lesions. Patients with oral lesions, however, had more severe disease (Psoriasis Area Severity Index [PASI], 3.9 vs 2.4; P=.05). Mean PASI was also higher in patients with fissured tongue (4.7 vs. 2.7, P=.03) and periodontitis (5.1 vs. 2.9, P=.04). (AU)

Angina bullosa haemorrhagica: A 14-year multi-institutional retrospective study from Brazil and literature review

Background: Angina bullosa haemorrhagica (ABH) is characterized by the recurrent appearance of blood blisters on the oral mucosa, mainly in adults' soft palate. In general, the blisters rupture spontaneously, lacking the necessity for biopsy. We report the clinical features of 23 ABH cases, emphasizing the clinical behavior and the management of these conditions. Material and Methods: A retrospective descriptive cross-sectional study was performed. A total of 12,727 clinical records of oral and maxillofacial lesions from four dental services in Brazil were analyzed. Clinical data were collected from the clinical records and evaluated. Results: The series comprised 12 males (52.2%) and 11 females (47.8%), with a mean age of 56.8 ± 14.6 years (ranging: 24-82 years) and a 1.1:1 male-to-female ratio. Most of the lesions affected the soft palate (n = 15, 65.2%). Clinically, the lesions presented mainly as an asymptomatic (n = 17, 73.9%) blood-filled blister that ruptured after a few minutes or hours, leaving an erosion. The masticatory trauma was the most frequent triggering event. No patient had coagulation disorders. A biopsy was performed in only four cases (17.4%). Treatment was symptomatic with a favorable outcome. Conclusions: ABH is still poorly documented in the literature, and its etiology remains uncertain. ABH mainly affects the soft palate of elderly adults and has a favorable evolution in a few days. The therapeutic approach is often focused only on the relief of symptoms. However, it can share some clinical features with more serious diseases. Therefore, clinicians must recognize these lesions to avoid misdiagnosis.(AU)

What is the frequency of floor of the mouth lesions? A descritive study of 4016 cases / ¿Cuál es la frecuencia de las lesiones del suelo de la boca? Un estudio descriptivo de 4016 casos

Background: The aim of this study was to investigate the frequency of oral lesions in the floor of the mouth fromrepresentative oral pathology centres in Latin America.Material and Methods: This study was conducted on biopsies obtained from January of 1978 to December of 2018at nine Latin America oral and maxillofacial pathology centres. Gender, age and histopathological diagnosis wereevaluated. Data were analysed using descriptive methods. Chi-square test was used for pairwise comparisons.Results: From 114,893 samples, 4,016 lesions (3.49%) occurred in the floor of the mouth. Brazil showed 3,777 cases(94%), Mexico 182 cases (4.5%) and Argentina 57 cases (1.4%). Benign lesions represented 65.1% (2,617 cases),followed by 34.9% (1,404 cases) of malignant disorders. Lesions of epithelial origin were more frequent (1,964) cases; 48.9%), followed by salivary glands (1,245 cases; 31%) and soft tissue lesions (475 cases; 11.7%). The mostcommon histological subtypes were oral squamous cell carcinoma (1,347 cases; 33.5%), ranula (724 cases; 18%), oralleukoplakia (476 cases; 11.8%) and inflammatory fibrous hyperplasia (239 cases; 5.9%). The lesion affected males in2,129 cases and females in 1,897 cases.Conclusions: In the current study, lesions in the floor of the mouth represented 3.49% of biopsies submitted to oralpathology services and oral squamous cell carcinoma, ranula and leukoplakia were the most common lesions.(AU)
