Objetivo: identificar las manifestaciones clínicas bucales de la enfermedad de Crohn y colitis ulcerosa en pacientes adultos mayores. Métodos: se efectuó un estudio descriptivo transversal con un universo de 50 adultos mayores, previamente diagnosticados por los especialistas gastroenterólogos, y prescritos con enfermedad de Crohn y colitis ulcerosa. Estos, confirmados por los hallazgos clínicos, histopatológicos y endoscópicos, remitidos a consulta estomatológica del Policlínico de Especialidades del Hospital Clinicoquirúrgico Universitario "Saturnino Lora Torres" de Santiago de Cuba, entre marzo de 2019 y marzo de 2020, practicándose el examen intrabucal, descripción de las lesiones bucales y su diagnóstico clínico. Para la recolección del dato primario se confeccionó un modelo con las variables: edad, sexo, enfermedad inflamatoria intestinal, localización anatómica, signos y síntomas clínicos orales en ambas patologías. Se creó una base de datos en SPSS versión 22.0 en Windows para el procesamiento y análisis de la información, usándose la técnica estadística descriptiva y agrupándose los datos en frecuencias absolutas y relativas. Resultados: en la serie resaltaron las personas de sexo femenino y el grupo de edades de 60 a 74 años, la pioestomatitis vegetante fue el signo bucal específico más común y la úlcera aftosa recurrente la lesión inespecífica de mayor predominio en ambas patologías. El dolor, el síntoma clínico de mayor afectación y el dorso de lengua el sitio de mayor predilección para su instalación. Conclusiones: las expresiones clínicas bucales más relevantes en pacientes adultos mayores con enfermedad de Crohn y colitis ulcerosa fueron la pioestomatitis vegetante y la úlcera aftosa recurrente.

Objective: Identify the oral clinical manifestations of Crohn´s disease and ulcerative colitis in elderly adults' patients. Methods: a cross-sectional descriptive study was carried out with a universe of 50 older adults previously diagnosed by gastroenterologist specialists, prescribing the presence of Crohn's disease and ulcerative colitis, confirmed by clinical, histopathologica and endoscopic findings, referred to the stomatological consultation of the Specialities Policlinic of the "Saturnino Lora Torres" University Clinical Surgical Hospital of Santiago de Cuba, from March 2019 to the same month of 2020, performing intraoral examination, description of oral lesions and their clinical diagnosis. For the collection of the primary data, a model was made with the variables: age, sex, inflammatory bowel disease, anatomical location, oral clinical signs and symptoms in both pathologies. A database was created in SPSS version 22.0 in Windows for the processing and analysis of the information, using the descriptive statistical technique and grouping the data in absolute and relative frequencies. Results: in the casuistry, females and the age group of 60 to 74 years prevailed, vegetative pyostomatitis was the most common specific oral sign and recurrent aphthous ulcer was the most prevalent non-specific lesion in both pathologies, pain being the most affecting clinical symptom and the back of the tongue is the most preferred site for its installation. Conclusions: the most relevant oral clinical expressions in elderly patients adults with Crohn´s disease and ulcerative colitis were pyostomatitis vegetative and recurrent aphthous ulcer.

Diagnosis and treatment strategies for patients with refractory recurrent aphthous ulcer and systemic diseases / 口腔疾病防治

@#Recurrent aphthous ulcer (RAU) is one of the most common diseases of the oral mucosa. At present, no effective method is available for RAU treatment, especially for refractory RAU, which significantly affects patients’ oral health and quality of life. Research shows that combination with systemic diseases greatly increases the difficulty of curing refractory RAU, making conventional oral ulcer treatment harder to perform effectively. This is probably because dentists commonly only focus on handling oral ulcers but neglect to think about the etiology of oral ulcers from a holistic perspective. Thus, we summarized some conditions of refractory RAU accompanied by systemic diseases, including inflammatory bowel disease, iron deficiency anemia, diabetes mellitus, Behçet’s disease, Reiter’s syndrome, sprue syndrome, Sutton syndrome, and acquired immunodeficiency syndrome. We also outlined the treatment principles of these patients. To be specific, on the one hand, dentists should cooperate with the relevant specialists to treat the systemic diseases, while on the other hand they should take measures including topical/general use of medicine, local physical therapy, Traditional Chinese medicine treatment, and psychotherapy for RAU management. This paper aims to provide clinicians with a more comprehensive understanding of the diagnosis and treatment of refractory RAU, in order to make personalized treatment plans for patients and improve the clinical efficacy of refractory RAU.

Systemic immune inflammation index in patients with recurrent aphthous stomatitis / Índice de inflamação imune sistêmica em pacientes com estomatite aftosa recorrente

Abstract Objectives: Recurrent Aphthous Stomatitis (RAS) a chronic idiopathic oral mucosal disease. But yet the etiology and pathogenesis of RAS are not exactly known, it is thought that inflammation play an important role in the pathogenesis. The aim of this study is to demonstrate the role of systemic inflammation among the possible etiological factors of RAS and to find the possible diagnostic correlation between Systemic Immune Inflammation Index (SII). Methods: Patients who were consulted the otolaryngology outpatient clinic and diagnosed with RAS between 2019-2021 were retrospectively analyzed. Neutrophil/Lymphocyte Ratio (NLR), Platelet/Lymphocyte Ratio (PLR) and SII values were calculated based on the results of complete blood count. Demographic and hematological parameters between control and RAS groups were compared. The statistical significance level was considered as <0.05. Results: There was no statistically significant difference between the control and RAS groups in terms of sex and age distributions (p = 0.566 and p = 0.173, respectively). SII, NLR and PLR values were significantly higher in the RAS group compared to the controls (p < 0.001, p < 0.001 and p = 0.001, respectively). A very strong correlation between SII and NLR, moderately strong correlation between SII and PLR and moderate correlation between NLR and PLR values were detected (respectively ρ: 0.813, 0.719, 0.532; p-values <0.001). Conclusion: SII, NLR and PLR has significantly higher levels in the RAS group compared to the control group, that it supports the role of systemic inflammation in the etiopathogenesis of RAS. In addition, the results show that SII is a valuable marker for inflammation. Level of evidence: 4. HIGHLIGHTS RAS is a chronic, idiopathic, ulcerative oral mucosal disease. SII is a new and inexpensive biomarker that can easily be calculated using the platelet, neutrophil, and lymphocyte count. SII may be a valuable marker to demonstrate the role of systemic inflammation in RAS etiopathogenesis. Vascular, thrombotic, and inflammatory processes are thought to have a role in RAS activation.

Resumo Objetivo: A estomatite aftosa recorrente (EAR) é uma doença crônica idiopática da mucosa oral. Embora sua etiologia e patogênese não sejam totalmente conhecidas, acredita-se que a inflamação possa desempenhar um papel importante. O objetivo deste estudo é demonstrar o papel da inflamação sistêmica entre os possíveis fatores etiológicos da estomatite aftosa recorrente e encontrar uma possível correlação diagnóstica com o índice de inflamação imunológica sistêmica, SII. Método: Foram analisados retrospectivamente pacientes avaliados no ambulatório de otorrinolaringologia e diagnosticados com estomatite aftosa recorrente entre 2019-2021. A relação neutrófilos/linfócitos, a relação plaquetas/linfócitos e os valores de SII foram calculados com base nos resultados do hemograma completo. Parâmetros demográficos e hematológicos dos grupos controle e de pacientes foram comparados. O nível de significância estatística foi considerado como <0,05. Resultados: Não houve diferença estatisticamente significante entre os grupos controle e com estomatite aftosa recorrente quanto à distribuição por sexo e idade (p = 0,566 e p = 0,173, respectivamente). Os valores de SII, a relação neutrófilos/linfócitos e a relação plaquetas/linfócitos foram significantemente maiores no grupo de pacientes em relação aos controles (p <0,001, p <0,001 e p = 0,001, respectivamente). Foi detectada uma correlação muito forte entre SII e relação neutrófilos/linfócitos, uma correlação moderadamente forte entre SII e relação plaquetas/linfócitos e uma correlação moderada entre valores da relação neutrófilos/linfócitos e relação plaquetas /linfócitos (ρ: 0,813, 0,719, 0,532 respectivamente; p-valores <0,001). Conclusão: SII, relação neutrófilos/linfócitos e relação plaquetas/linfócitos apresentam níveis significantemente maiores no grupo com estomatite aftosa recorrente quando comparados ao grupo controle, o que corrobora o papel da inflamação sistêmica na sua etiopatogênese. Além disso, os resultados mostram que o SII é um marcador inflamatório valioso. Nível de evidência: 4. HIGHLIGHTS A estomatite aftosa recorrente é uma doença ulcerativa crônica idiopática da mucosa oral. O SII (do inglês Systemic Immune Inflammation Index) é um biomarcador novo e de baixo custo que pode ser facilmente calculado que usa a contagem de plaquetas, neutrófilos e linfócitos. O SII pode ser um marcador valioso para demonstrar o papel da inflamação sistêmica na etiopatogênese da estomatite aftosa recorrente. Acredita-se que processos vasculares, trombóticos e inflamatórios tenham um papel na ativação da estomatite aftosa recorrente.

Effect of Dentoxol® in the treatment of recurrent mild aphthous ulcers. A prospective observational pilot study

ABSTRACT: Background: Recurrent aphthous stomatitis (RAS) is the most common oral ulceration. Its prevalence in the general population varies between 5% and 60%, and during the acute period, it causes pain and interferes with basic activities, such as eating, swallowing and talking. Dentoxol® is a medical mouthrinse that cleans, moisturizes and lubricates the mouth, mechanically stimulating local epithelial regeneration. The aim of this study was to evaluate the efficacy of Dentoxol® in improving the general state of patient with minor RAS using two different treatment schemes. Material and methods: Thirty-nine patients with RAS were recruited in a prospective observational pilot study. Two dosing regimens, 5 ml of Dentoxol® twice daily and 5 ml of Dentoxol® three times daily were evaluated. Results: Efficacy to improve the general state was significant superior in "Three time daily" group compared with "twice daily" at 72 h (66% vs 33% respectively). No pain was reported in approximately 90% of cases at 96 h of use in both group without significant differences between the groups in any evaluation time-point. Conclusion: Despite the limitations of these preliminary data, Dentoxol® shows promising beneficial properties for the management of minor RAS.

The Clinical Efficacy of Minocycline Mouth Rinse on Recurrent Aphthous Stomatitis—A Randomized Controlled Trial

Introduction: Recurrent aphthous stomatitis (RAS) is one of the most common ulcerative diseases affecting the general population. The present study aimed to evaluate the clinical efficiency of 0.5% minocycline mouth rinse prescribed along with the topical anesthetic gel and vitamin supplement over the topical anesthetic gel and vitamin supplement prescribed alone for treating RAS. Materials and Methods: A total of 60 participants were randomly divided into two groups—experimental group: 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel; and control group: vitamin supplement and topical anesthetic gel alone. The pain symptoms were evaluated using the VAS scores at baseline and first follow?up visits. The data were analyzed using Student’s t test. Results: A significant reduction in the pain scores was observed in participants using the 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel on the first follow?up visit (P = < 0.001). Conclusion: The 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel had shown more reduction in the pain symptoms when compared to topical anesthetic gel and vitamin supplement prescribed alone for the treatment of RAS.

Neural network analysis of the correlation between malnutrition-induced stomatitis and vitamin B12 and folic acid / 口腔疾病防治

Objective@# A model was built by neural network analysis to study the relationship between different degrees of vitamin B12 and folic acid deficiency and malnutrition-induced stomatitis.@*Methods@# Data from 30 healthy volunteers and 30 patients with malnutrition-induced stomatitis were collected. The distribution of lesions, the number of affected sites and clinical manifestations were recorded, and the severity was scored. The levels of vitamin B12 and folic acid in the peripheral blood of the two groups were simultaneously measured. The SPSS software was used to analyze the correlation between vitamin B12 and folic acid levels in the peripheral blood of patients with malnutrition-induced stomatitis and healthy volunteers, and the MATLAB software package was used to analyze the data via a neural network.@*Results@#The levels of vitamin B12 and folic acid significantly correlated with the grade of malnutrition-induced stomatitis. Simultaneous B12 and folic acid deficiency linearly correlated with the occurrence and severity of malnutrition-induced stomatitis. Based on this correlation, a thermogram model of malnutrition-induced stomatitis was constructed.@*Conclusion@# Malnutrition-induced stomatitis is closely related to vitamin B12 and folic acid deficiency. Their synergistic effect may promote the occurrence and development of malnutrition-induced stomatitis. The construction of the malnutrition-induced stomatitis model aids the targeted etiological treatment of patients with moderate and severe deficiency to prevent malnutrition-induced stomatitis.

Eficacia clínica del extracto de Matico (Piper angustifolium) en la evolución de la cicatrización de heridas por estomatitis aftosa recidivante / Clinical efficacy of Matico extract (Piper angustifolium) in the evolution of wound healing due to recurrent aphthous stomatitis

La estomatitis aftosa recurrente (EAR) es un trastorno ulcerativo doloroso cíclico que comúnmente afecta la mucosa oral. Factores locales y sistémicos como trauma, sensibilidad alimentaria, deficiencias nutricionales, condiciones sistémicas y desórdenes inmunológicos están asociados con el desarrollo de la enfermedad. Debido a las similitudes en las características de las úlceras pépticas y las úlceras aftosas orales, parece razonable suponer que Helicobacter pylori podría desempeñar un papel en el desarrollo de la EAR. Las especies de Piper son plantas aromáticas que se utilizan como especias en la cocina, pero sus metabolitos secundarios también han mostrado efectos biológicos sobre la salud humana. El objetivo del presente estudio fue determinar la relación entre H. pylori y EAR y el efecto cicatrizante del extracto Matico sobre las ulceras bucales. Se reclutó a cuarenta sujetos con EAR. Los participantes fueron asignados al azar al grupo de prueba o al grupo de control. El tamaño y número de las úlceras se registraron el día 1 (valor inicial) y el día 30 (valor final). El tamaño de la ulceras, presencia de pseudomembranas y halos eritematosos fueron estadisticamente significativas en relación a la positividad de H. pylori (p <0,05). No hubo diferencias significativas entre la morfología, número y localización de las aftas (p> 0,05). El grupo que recibió el extracto tuvo un porcentaje de mejoría en la reducción del número de aftas del 65% el día final de evaluación en comparación de sólo un 25% del grupo que no recibió el extracto Matico(AU)

Recurrent aphthous stomatitis (RAS) is a cyclic painful ulcerative disorder that commonly affects the oral mucosa. Local and systemic factors such as trauma, food sensitivity, nutritional deficiencies, systemic conditions, immunological disorders and genetic polymorphisms are associated with the development of the disease. Because of similarities in the characteristics of peptic ulcers and oral aphthous ulcers, it seems reasonable to hypothesize that Helicobacter pylori could play a role in the development of RAS. Piper species are aromatic plants used as spices in the kitchen, but their secondary metabolites have also shown biological effects on human health. The aim of the present study was to determine the relationship between H. pylori and RAS and the healing effect of Matico extract on mouth ulcers. Fuorty subjects with RAS were recruited. The participants were randomly allocated to the test group or the control group. The size and number of ulcers were recorded on day 1 (initial value) and day 30 (final value). The size of the ulcers, the presence of pseudomembranes and erythematous halos were statistically significant in relation to the positivity of H. pylori (p <0.05). There were no significant differences between the morphology, number and location of the canker sores (p> 0.05). The group that received the extract had a percentage improvement in the reduction of the number of canker sores of 65% on the final day of evaluation compared to only 25% of the group that did not receive the Matico extract(AU)

Manifestaciones bucales de la enfermedad celíaca y alergia al trigo: Reporte de tres casos y revisión literatura / Oral Manifestations of Celiac Disease and Wheat Allergy: Report of Three Cases and Review of Literature

Resumen: La Enfermedad Celíaca (EC) es una enfermedad sistémica inmunomediada, provocada por el gluten y prolaminas relacionadas, en individuos genéticamente susceptibles. Se caracteriza por manifestaciones clínicas dependientes del gluten, anticuerpos específicos de EC, haplotipos HLA DQ2 o DQ8 y enteropatía. La mayoría de los pacientes son asintomáticos o con manifestaciones leves. Afecta principalmente el sistema gastrointestinal causando síntomas y signos como diarrea, dolor abdominal recurrente y distensión abdominal; además manifestaciones extradigestivas. Los pacientes con EC pueden tener manifestaciones bucales que incluyen estomatitis aftosa recurrente (EAR), hipoplasia del esmalte, glositis atrófica, entre otras. El diagnóstico de EC se basa en la historia clínica, serología, endoscopía e histología. Existen otras entidades que deben diferenciarse de la EC, como la sensibilidad al gluten no celíaca y la alergia al trigo. El objetivo de este trabajo es presentar tres pacientes con antecedentes de EAR y otras manifestaciones clínicas asociadas al diagnóstico precoz de EC y alergia alimentaria.

Abastract: Celiac Disease (CD) is an immune-mediated systemic disease, caused by gluten and related prolamins, in genetically susceptible individuals. It is characterized by gluten-dependent clinical manifestations, CD-specific antibodies, HLA DQ2 or DQ8 haplotypes, and enteropathy. Most patients are asymptomatic or with mild manifestations. It mainly affects the gastrointestinal system causing symptoms and signs such as diarrhea, recurrent abdominal pain and abdominal distension; also extradigestive manifestations. Patients with CD may have oral manifestations that include recurrent aphthous stomatitis (RAS), enamel hypoplasia, atrophic glossitis, among others. The diagnosis of CD is based on clinical history, serology, endoscopy and histology. There are other entities that should be differentiated from CD, such as non-celiac gluten sensitivity and wheat allergy. The aim of this study is to present three patients with a history of RAS and other clinical manifestations associated with the early diagnosis of CD and food allergy.

Detection and significance of immune function in oral mucosa-associated diseases / 口腔疾病防治

@#The evaluation of immune function plays an important role in the diagnosis, treatment and prognosis of many diseases. To date, immune function detection includes cellular immunity, humoral immunity, and inflammatory markers. In this paper, the application of immune function detection in the diagnosis, differential diagnosis and treatment monitoring of various diseases was discussed; then, the application value of immune function detection in the diagnosis and treatment of three common oral mucosa-related diseases, including recurrent aphthous ulcer (RAU), oral lichen planus (OLP), and oral squamous cell carcinoma (OSCC), were reviewed combined with the literature and our research. Our research found that RAU patients present abnormal humoral immune function and obvious inflammatory reactions, whereas OLP and OSCC patients present mild inflammatory reactions and more serious abnormal cellular and humoral immune function, so the combined detection of immune function has a certain guiding value for the diagnosis and treatment of these diseases. Moreover, in the future, it is necessary to carry out a study on large sample, multicenter and multiindex joint detection to better clarify the role of immune dysfunction in the pathogenesis of various diseases and its mechanism, to establish the corresponding diagnostic model and prognostic prediction model, to find more effective treatment methods.

Research progress on the role of T helper cells 17 and interleukin 17 in oral mucosal diseases / 口腔疾病防治

@#T helper 17 (Th17) cells are a new type of CD4+ T helper cell. They participate in the immune and inflammatory response by secreting specific interleukin-17 (IL-17). In oral mucosal diseases, oral lichen planus (OLP), recurrent aphthous ulcer (RAU) and Behcet′s disease (BD) are associated with Th17 cells and IL-17. There were 17 kinds of proteins in the saliva of patients with OLP that could upregulate the expression of Th17 cells and induce the secretion of IL-17. IL-17 can stimulate epithelial cells, endothelial cells and fibroblasts to produce a variety of cytokines, such as IL-6, IL-8, granulocyte macrophage colony-stimulating factor and cell adhesion molecule-1, leading to the production and aggravation of inflammation. Th17/Tc17 cell-targeted therapy can significantly improve the clinical symptoms of OLP patients′ mucosa and skin. IL-17 can stimulate oral keratinocytes through the IL-17RA or IL-17RE receptor and produce proinflammatory effects in RAU. Th17 cells in the peripheral blood of BD patients are significantly increased, while Treg cells are significantly decreased.

Impacto de enfermedades orales asociadas a estrés sobre la calidad de vida / Impact on Quality of Life of Oral Diseases Related to Stress

Resumen: Se ha sugerido que enfermedades de la mucosa oral asociadas a estrés impactan negativamente la calidad de vida. Sin embargo, la información no es concluyente. El objetivo fue comparar la calidad de vida asociada a salud bucal en dos grupos: Casos (21 pacientes de una clínica de enseñanza de medicina bucal con diagnóstico de liquen plano oral, estomatitis aftosa recurrente y síndrome de boca dolorosa; Control (42 sujetos sanos) pareados por edad y género. Se aplicó el cuestionario perfil de impacto de salud oral. Resultados: El análisis estadístico mostró que el grupo casos tiene peor calidad de vida (p 0.03) comparado con el de los controles, específicamente en las dimensiones incomodidad psicológica (p 0.027); inhabilidad física (p 0.004); e incapacidad (p 0.002; RM 5.63 IC 1.58-20.80). Se concluye que los sujetos que padecen enfermedades de la mucosa oral relacionada a estrés tienen mala calidad de vida.

Abstract: It has been suggested that oral mucosa diseases related to stress have a negative impact on the quality of life. However, the information regarding which aspects are the most affected is inconclusive. The objective was to compare the quality of life associated with oral health in two groups: Cases formed by 21 patients coming from a teaching clinic, suffering oral lichen planus, recurrent aphthous stomatitis, and burning mouth syndrome; Control formed by 42 healthy subjects matched for age and gender. Oral Health Impact Profile questionnaire was applied. Statistical analysis showed that group Cases has worse quality of life (p 0.03) than the one of controls, specifically on psychological discomfort (p 0.027), physical disability (p 0.004); and handicap dimensions (p 0.002; RM 5.63 IC1.58-20.80). It was concluded that patients suffering oral mucosa disease related to stress showed poor quality of life.

Estomatitis aftosa recurrente y deficiencias nutricionales: Reporte de tres casos y revisión de literatura / Recurrent Aphthous Stomatitis and Nutritional Deficiencies: Report of Three Cases with Literature Review

RESUMEN Introducción: La estomatitis aftosa recurrente (EAR) es la enfermedad ulcerativa más común que afecta la mucosa oral no queratinizada. La etiología aún se desconoce, pero se han propuesto varios factores locales y sistémicos como agentes causales. Descripción del caso: se informa tres pacientes con presencia de EAR asociada a deficiencias nutricionales, debidas a dietas de restricción alimentaria. El primer caso, una mujer de 19 años con deficiencia de hierro, refirió tomar té verde a diario y consumir poca cantidad de carbohidratos, grasas y carne. El segundo caso, un hombre de 32 años con deficiencia de hierro y vitamina B12 asociada a dieta tipo vegana, aunque a veces si consumía carne. El tercer caso, hombre de 50 años, vegano y exfumador desde hace un año, presentó deficiencia de hierro, vitamina B12 y ácido fólico. En los tres casos un detallado interrogatorio, examen clínico y análisis sanguíneo completo, permitió establecer un adecuado diagnóstico, manejo odontológico y derivación con un nutricionista, con el fin de tratar la patología de base y no sólo brindarles un tratamiento sintomático de las lesiones. Discusión: Ante un cuadro de EAR es recomendable realizar un análisis que incluya hemograma, ácido fólico, hierro y vitamina B12, para descartar posibles causas sistémicas y eventualmente tratarlas. El manejo clínico tiene como objetivo mejorar la función del paciente y la calidad de vida mediante terapias tópicas y sistémicas; sin embargo, es fundamental identificar y controlar los factores causales que contribuyen; así como, la exclusión o tratamiento de la enfermedad sistémica subyacente.

ABSTRACT Introduction: Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease that affects the non-keratinized oral mucosa. The etiology is still unknown, but several local and systemic factors have been proposed as causal agents. Case description: three patients are reported with RAS associated with nutritional deficiencies, due to dietary restriction diets. The first case, a 19-year- old woman with iron deficiency, reported taking green tea daily and consuming a small amount of carbohydrates, fats and meat. The second case, a 32-year-old man with iron deficiency and vitamin B12 associated with vegan diet, although sometimes if he consumed meat. The third case, man of 50 years, vegan and ex-smoker for a year, presented deficiency of iron, vitamin B12 and folic acid. In all three cases a detailed questioning, clinical examination and complete blood analysis allowed to establish an adequate diagnosis, dental management and referral with a nutritionist, in order to treat the underlying pathology and not only provide a symptomatic treatment of the injuries. Discussion: In the setting of RAS, it is advisable to perform an analysis that includes a blood count, folic acid, iron and vitamin B12, to rule out possible systemic causes and eventually treat them. Clinical management aims to improve patient function and quality of life through topical and systemic therapies; however, it is essential to identify and control the causal factors that contribute; as well as, the exclusion or treatment of the underlying systemic disease.

Clinical Characteristics of Patients with Recurrent Aphthous Stomatitis

Recent studies indicate that oral health of the human population, unfavorable trends persist. Despite several researches conducted both in Uzbekistan and abroad, the etiology and pathogenesis of recurrent aphthous stomatitis remains unexplained. The aim of the study is to assess the clinical status of patients with recurrent aphthous stomatitis and develop a method of treatment and prevention. Methods: 106 patients with recurrent aphthous stomatitis were diagnosed. The frequency of exacerbations of RAS ranged from 1 to 4 or more relapses per year, the duration of the disease was more than one year. Results: 72.2% of cases (44 people) were women aged 18-29 years, among men a greater number of complaints - 17 (27.8% cases). Disease duration of recurrent aphthous stomatitis in the patients participating in the study averaged 5.17±0.38 years. 41 people suffered from RAS 1 to 3 years. In 38 patients, the disease duration ranged from 3.1 to 5 years, in 12 people, RAS was observed from 5.1 to 7 years, 15 patients suffered from the pathology under study for more than 7 years. Conclusions: Timely early diagnosis of RAS is not only completely cure for patient, avoid complications, but also revise the low efficiency of traditional methods of the treatment.

Study on the correlation between common diseases of oral mucosa and psychological factors / 口腔疾病防治

Objective@#To explore the relationship between psychological factors and recurrent aphthous ulcer (RAU), oral lichen planus (OLP), and burning mouth syndrome (BMS) and to provide a reference for clinical diagnosis and treatment of the disease.@*Methods@#From July to October 2018, 50 patients with common RAU, refractory RAU, OLP and BMS were selected as the observation group, and 50 healthy participants without major systemic diseases and oral mucosal diseases matched for age and sex served as the control group. The psychological status of the subjects in each group was investigated by questionnaires, including the generalized anxiety disorder 7-item scale(GAD-7) and the patient health questionnaire-9 (PHQ-9).@*Results@#Compared with the control group, the PHQ-9 scores in the refractory RAU, common RAU, OLP and BMS groups were higher than those in the control group (P < 0.05), and the GAD-7 scores in the refractory RAU, OLP and BMS groups were higher than those in the control group (P < 0.05). In the RAU group, the GAD-7 score of intractable RAU was higher than that of common RAU (P < 0.05), and there was no significant difference in the PHQ-9 score (P > 0.05).@*Conclusion @#RAU, OLP and BMS are common psychosomatic diseases presented by patients in the Department of Oral Mucosal Diseases. Their occurrence and development are related to the psychological status of patients. A tendency toward anxiety is significantly more common among refractory RAU patients than common RAU patients.

Clinical analysis of vitamin B12 deficiency mainly manifested by recurrent aphthous ulcers / 口腔疾病防治

Objective@# To analyze the clinical characteristics and treatment experience of Vitamin B12 (VB12) deficient patients with recurrent aphthous ulcers (RAU) to improve the clinical efficacy. @*Methods@#A retrospective analysis was performed on 15 cases of recurrent oral ulcers from January 2016 to September 2018. The causes were analyzed according to the patients’ clinical characteristics. @*Results@# In total, 15 patients with RAU had no remission after routine immunotherapy. Further clinical examination suggested that vitamin B12 levels were reduced. The erythrocyte mean corpuscular volume (MCV) was significantly increased, and the average number of red blood cells (RBC) and hemoglobin (Hb) levels were decreased. RAU disappeared after vitamin B12 supplementation. Routine blood work showed that the MCV returned to the normal range, which was statistically significant compared with the pretreatment MCV (P < 0.001). Vitamin B12 serum levels were significantly higher (P < 0.001) than those before treatment.@*Conclusion @#When the main manifestation of vitamin B12 deficiency is recurrent oral ulcer symptoms, dentists should examine the lesions carefully, inquire about the medical history in detail, and perform further serological tests when necessary to avoid the overuse of immunosuppressive drugs for treatment.
