Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Prevalence of lectures about dental esthetics and female speakers in three Brazilian conferences

Abstract This study analyzed the prevalence of lectures involving esthetics in the scientific program of Brazilian dental conferences and the gender distribution of speakers. All lectures presented in three dental conferences (Bahia, São Paulo, and Goiás states) held from 2016 to 2020 were evaluated. Three investigators individually divided the lectures according to the specialties recognized by the Brazilian Federal Council of Dentistry (FCD) based on their titles. The lectures were also classified as involving or not esthetics, and the speaker`s gender was recorded. Descriptive statistical analyses were performed, and Chi-square tests assessed possible associations between factors. The words most cited in the titles of the lectures were "esthetic" (13.6%), "dentistry" (9.9%), and "treatment" (8.1%). Oral diseases were barely mentioned in the titles (up to 1.3%). The highest number of lectures was observed for the specialty of Restorative Dentistry (22.3%), followed by Prosthodontics (18.5%). Approximately one-third of lectures involved some aesthetic aspect, but this percentage ranged from 71.9 to 78.6% for the two specialties with more lectures. Regarding the speaker`s gender, the inequity was higher for lectures involving esthetics (81.6% of males) than for topics unrelated to esthetics (66.7%). More male speakers than females were observed for all specialties. The highest gender gap was observed for Pediatric Dentistry with 62.4% male speakers, although only 10.6% of FCD registered specialists were men. In conclusion, the Brazilian dental conferences analyzed seemed to favor offering lectures dealing with esthetic topics and male speakers.

Resumo Este estudo analisou a prevalência de palestras envolvendo estética na programação científica de congressos de Odontologia brasileiros, e a distribuição do gênero dos palestrantes. Todas as palestras apresentadas em três congressos de Odontologia (CIOBA, CIOGO, and CIOSP) entre 2016 e 2020 foram avaliadas. Três avaliadores utilizaram os títulos das palestras para dividi-las entre as especialidades reconhecidas pelo Conselho Federal de Odontologia (CFO) do Brasil. As palestras foram também classificadas como envolvendo ou não estética, e o gênero do palestrante foi registrado. Análises estatísticas descritivas foram realizadas, e testes de Qui-quadrado avaliaram possíveis interações entre fatores. A palavra mais citada nos títulos das palestras foi "estética" (13,6%), seguido por "odontologia" (9,9%) e "tratamento" (8,1%). Doenças orais foram raramente mencionadas nos títulos (até 1,3%). O maior número de palestras foi observado para a especialidade de Dentística (22,3%), seguido por Prótese Dental (18,3%). Aproximadamente um terço das palestras envolviam algum aspecto estético, com porcentagens entre 71,9 a 78,6% para as duas especialidades com mais palestras. Em relação ao gênero do palestrante, a inequidade foi maior para palestras envolvendo estética (81,6% de homens) que para tópicos não relacionadas à estética (66,7%). Mais palestrantes do sexo masculino que feminino foram observados para todas as especialidades. A maior discrepância entre os gêneros foi observada para Odontopediatria, uma especialidade com 62,4% dos palestrantes do sexo masculino, embora apenas 10,6% dos especialistas registrados no CFO eram homens. Como conclusão, os congressos de Odontologia Brasileiros parecem preferir palestras abordando tópicos de estética e palestrantes do sexo masculino.

Autofagia en el Contexto del Sistema Estomatognático en Enfermedades No Neoplásicas. Revisión Sistemática Exploratoria

La autofagia es un proceso de degradación lisosomal y protección celular, que está destinado a eliminar los orgánulos dañados, las proteínas mal plegadas y los patógenos intracelulares, por lo cual es un importante proceso para la salud en los humanos. La autofagia actúa como modulador de la patogénesis y es un objetivo terapéutico potencial en diversas enfermedades, como el cáncer, la diabetes o el Parkinson. En relación al sistema estomatognático, la autofagia actúa agravando o protegiendo las enfermedades orales cuando se encuentra aumentada, activada o alterada. La desregulación de los mecanismos de la autofagia repercute en el desarrollo de la autoinmunidad a través de la supervivencia de linfocitos T, participa en la disminución y degeneración de células glandulares y queratinocitos basales en patologías como el síndrome de Sjögren o el liquen plano oral; participa modulando la inflamación, pero también defendiendo a la cavidad oral del ataque de patógenos externos que pueden causar, por ejemplo, la enfermedad periodontal. Esta revisión sistemática exploratoria, describe los mecanismos generales involucrados de la autofagia en diferentes patologías no neoplásicas que afectan al sistema estomatognático.

Autophagy is a process of lysosomal degradation and cell protection, which is intended to eliminate damaged organelles, misfolded proteins, and intracellular pathogens, making it an important process for human health. Autophagy acts as a modulator of pathogenesis and is a potential therapeutic target in various diseases, such as cancer, diabetes, or Parkinson's. In relation to the stomatognathic system, autophagy acts as aggravating or protecting oral diseases when it is increased, activated, or altered. The deregulation of autophagy mechanisms affects the development of autoimmunity through the survival of T lymphocytes and participates in the decrease and degeneration of glandular cells and basal keratinocytes in pathologies such as Sjögren's syndrome or oral lichen planus; It participates by modulating inflammation, but also by defending the oral cavity from the attack of external pathogens that can cause, for example, periodontal disease. This exploratory systematic review describes the general mechanisms involved in autophagy in different non-neoplastic pathologies that affect the stomatognathic system.

Research progress on oral characterization of Corona Virus Disease 2019 / 口腔疾病防治

@#Corona Virus Disease 2019 (Corona Virus Disease 2019,COVID-19) has become a public health emergency that has attracted global attention because of its large-scale outbreak resulting in numerous human infections and deaths. COVID-19 is a highly contagious respiratory disease caused by novel coronavirus 2019-nCoV. Due to a large number of infections and fast transmission speed, it's significant to diagnose the infected people quickly and detect the asymptomatic infected people as soon as possible. At present, the preliminary screening is judged by the clinical manifestations of the patients, mainly involving the respiratory system, but recent studies have found that the patients infected with COVID-19 have unique oral manifestations, such as taste disturbance, xerostomia, halitosis, inflammation of salivary glands, necrotizing periodontal disease and some of them are earlier than typical symptoms such as dry cough, fever, etc. Paying attention to the oral manifestations of patients can further improve the COVID-19 screening procedure. At present, symptomatic treatment is mainly used for these oral symptoms.

Clinical problems and outcome indicators in the expert consensus determined by the Delphi method of 5-aminolevulinic acid photodynamic therapy for the treatment of oral potential malignant diseases / 口腔疾病防治

Objective@#To determine the clinical problems and outcome indicators that need to be included in the expert consensus of 5-aminolevulinic acid (ALA) photodynamic therapy in the treatment of oral potential malignant diseases. @*Methods@# Based on the relevant literature, the clinical problems and outcome indicators were drafted during the meeting. The Delphi method was used for expert consultation and expert opinion collection. The average and standard deviation of the voting results were calculated to determine the importance of the indicators, and the positive coefficient, variation coefficient and coordination coefficient were calculated for quality control. @* Results@#In the first round of the Delphi method, 12 outcome indicators (the main reference elements include photon integral flux, power density, illumination time, and spot diameter were identified; the specific parameters are photon integral flux of 100 J/cm2 and power density of 100-600 mW/cm2. A diode laser of (630 ± 5) nm wavelength should be chosen. The analgesic regimen is local anesthesia supplemented by hypothermia and intermittent laser irradiation before treatment. Lesions with hyperkeratotic require pretreatment. The concentration of ALA administered was set at 20%. Eight clinical problems (main reference elements of photodynamic irradiation dose, specific parameters, choice of light source, evaluation criteria of efficacy, prevention of adverse effects, dosing concentration, whether oral potentially malignant diseases with hyperkeratosis should be pretreated, administration of photosensitizers) were included according to the literature and expert discussion. In the second round, 89 experts completed the questionnaire and gave very important evaluations of 9 outcome indicators (the main reference elements included photon integral flux, power density and illumination time; the specific parameters were a photon integral flux of 100 J/cm 2 and a power density of 100-600 mW/cm2). A diode laser of (630 ± 5)nm wavelength should be chosen. The concentration of ALA administered was set at 20%. Six clinical problems (main reference elements of photodynamic irradiation dose, specific parameters, choice of light source, evaluation criteria of efficacy, dosing concentration, administration of photosensitizers), and the remaining 3 were given important evaluations, with good consistency.@*Conclusion@# In this study, the irradiation dose, mode of administration and concentration, evaluation criteria of efficacy, prevention of adverse effects and pretreatment regimen of ALA photodynamic therapy for oral potentially malignant diseases determined by the Delphi method had good agreement among experts.

Research progress on salivary exosomes and oral diseases / 口腔疾病防治

@#Salivary exosomes are extracellular vesicles with a diameter of 30-50 nm in saliva. With the development of technology in recent years, many studies have revealed that salivary exosomes play an important role in the occurrence and development of various oral diseases. For example, salivary exosomal CD9 and CD81 promote tumor cell metastasis by regulating the cell adhesion and movement, salivary exosomal miR-24-3p promotes the tumor cell proliferation by acting on PER1, and salivary exosomal programmed cell death-ligand 1 (PD-L1) mRNA inhibits the destruction of inflammatory tissue, which can be biomarkers for the diagnosis of oral cancer, periodontitis and other oral diseases. Therefore, salivary exosomes can be used as potential prognostic and diagnostic markers for oral diseases. In addition to oral diseases, such as oral cancer, periodontitis, oral lichen planus, Sjogren’s syndrome, etc., salivary exosomes are closely related to distant tumors, such as pancreatic cancer, lung cancer, and systemic diseases, such as Parkinson’s disease, inflammatory bowel disease, etc. It is of great significance to study the role of salivary exosomes in the diagnosis and treatment of oral and systemic diseases and to develop the potential of salivary exosomes as biomarkers for disease diagnosis.

Diagnostic strategies for oral manifestations of infectious diseases / 浙江大学学报·医学版

Infectious diseases are caused by infection of organism with pathogenic agents, which may lead to epidemics. Many infectious diseases such as syphilis, diphtheria, measles, and acquired immunodeficiency syndrome have specific and non-specific manifestations in the oral cavity. However, the same disease may have different oral manifestations in different patients clinically. We can apply the strategy of "three unusuals and one change" in clinical reasoning for diagnosis of infectious diseases with oral manifestations. The so-called "three unusuals" refer to unusual age, unusual location and unusual effect, and "one change" means the change from rare to common. In this article, we will give a comprehensive introduction about the oral manifestations of common communicable diseases and their diagnostic strategies.

Vitamin B12 deficiency masquerading Addison’s disease: a case report of an adolescent male

Intraoral pigmentations range from innocuous physiologic pigments to life-threatening malignant conditions. It is at the discretion of the observing clinician to identify the abnormal clinical manifestations and provide necessary intervention. There are controversies about delineating the definite etiology of the pigmentation such as race, exposure to ultra-violet radiation, drug-induced pigmentation post-inflammatory pigments of the oral cavity.

Programa de Promoción y Educación para la Salud Bucal, Destinado a Niños y Adolescentes Hospitalizados / Oral Health Education and Promotion Program for Hospitalized Children and Adolescents

La enfermedad sistémica es uno de los riesgos asociados al desarrollo de enfermedades bucales. Este programa fue orientado a promover la salud bucal de niños y adolescentes internados en la clínica de la cátedra de Pediatría del Hospital de Clínicas "José de San Martín". Se realizó un estudio descriptivo transversal sobre una muestra de 1140 individuos registrados entre los años 2008 y 2018. El objetivo fue analizar las variables que afectan su salud bucal. Para ello, cursantes de la Carrera de especialización en Odontopediatría de la UBA implementaron semanalmente un Programa de Promoción y Educación para la salud bucal, destinado a niños internados y sus acompañantes. Para el registro de caries se utilizó el Índice de Necesidad de Tratamiento comunitario (INTc), se analizó la dieta, el riesgo social y la presencia o no de cepillo dental. Se realizó prueba de Chi cuadrado para la comparación de las variables cualitativas, cálculo de medias, rangos, porcentajes y desvíos. Como resultado se observaron diferencias significativas del INTc en los pacientes con dieta cariogénica entre los distintos grupos de edad. El coeficiente asociado a la dieta es aproximadamente 5 veces mayor que el asociado al uso de cepillo. El INTc evidenció una media en preescolares de 2.45 con DS 2.47, en escolares de 4.59 con DS de 3.33 y en adolescentes fue de 4.02 con DS de 3.15. En conclusión, la salud bucal no está separada de la salud general, por lo que se destaca la necesidad de incorporar al odontólogo dentro del grupo interdisciplinario que atiende a niños hospitalizados. La dieta cariogénica fue la covariables con mayor efecto y luego el uso de cepillo dental (AU)

Aerosol transmission prevention of novel coronavirus in dental clinics / 上海交通大学学报（医学版）

Corona virus disease 2019 (COVID-19), which broke out in Wuhan, HuBei in December, 2019, spread around the country in a short term. Some infected patients suffered from severe acute respiratory syndrome. It has become a major public health event of international concern. COVID-19 patients are the main source of transmission and most people get infection easily, so the current main prevention method is interrupting the pathway of transmission. The dental treatments are very special because these operations produce substantial aerosols and lead a high risk of cross-infection, which brings challenge for epidemic prevention and control. In this paper, the characteristics of aerosols and prevention methods of aerosol transmission in dental clinics are mainly discussed.

Halitosis en otorrinolaringología: una revisión de la literatura / Halitosis in otolaryngology: a review of the literature

RESUMEN La halitosis es un motivo de consulta frecuente y que puede repercutir de gran manera en la calidad de vida de quien la presenta. Puede dividirse en halitosis genuina, pseudohalitosis y halitofobia. De las halitosis genuinas, cerca del 90% son secundarias a patología de la cavidad oral. En otorrinolaringología, las principales causas responden a tonsilolitiasis, patología rinosinusal y cuerpos extraños nasales. Existen distintos métodos diagnósticos que permiten medir e identificar la halitosis, con sus beneficios y desventajas. Las medidas generales de higiene oral, así como intervenciones específicas deben estar basadas en la evidencia a cargo de un equipo multidisciplinario que permita garantizar mejores resultados.

ABSTRACT Halitosis is a frequent health problem, that can have a huge impact in the quality of life of those affected. It can be classified as genuine halitosis, pseudohalitosis and halitophobia. Of genuine halitosis, approximately 90% is originated from the oral cavity. In otorhinolaryngology, most frequent causes are tonsiloliths, rhinosinusitis and nasal foreign bodies. There are different diagnostic methods, each one with its benefits and disadvantages. General measures of oral hygiene, as specific interventions must be evidence-based in charge of a multidisciplinary team that guarantees better results.

Material e Métodos: estudo transversal e retrospectivo em que prontuários de 2078 pacientes foram avaliados e dados referentes às doenças, idade, gênero, cor da pele e localização anatômica das lesões foram coletados e analisados de forma descritiva. Resultados: 69% dos pacientes (1441 casos) obtiveram o diagnóstico conclusivo através de exame histopatológico, ao passo que 31% (637 casos) obtiveram um laudo histopatológico descritivo. Dos casos com diagnóstico histopatológico conclusivo, 58% eram mulheres, 31% homens e em 11% o sexo não foi informado. A média de idade da população estudada foi de 50,63 anos e em 58% dos casos os pacientes eram leucodermas. O maior número de lesões foram as do grupo dos processos proliferativos não-neoplásicos, sendo a hiperplasia fibrosa inflamatória (30,1%) a mais prevalente. Conclusão: o perfil epidemiológico do paciente atendido no período estudado foi composto predominantemente por mulheres com mais de 50 anos de idade e a lesão oral mais prevalente foi a hiperplasia fibrosa inflamatória. Este estudo reforça a importância do papel da análise histopatológica como método auxiliar de diagnóstico e que possibilita a elaboração de estratégias específicas para prevenção e detecção precoce das doenças orais mais frequentes na população

Objective: to evaluate the prevalence of the main types of lesions submitted to biopsy and to identify the profile of patients attended at the Stomatology Clinics of the Piquet Carneiro Polyclinics (PPC/UERJ, Rio de Janeiro) between 2000 and 2012. Material and methods: this is a cross-sectional and retrospective study in which medical records of 2,078 patients were evaluated and data referring to diseases, age, sex, skin color and anatomical location of the lesions were collected and analyzed descriptively. Results: A total of 69% of patients (1,441 cases) obtained the conclusive diagnosis by histopathological examination, whereas 31% (637 cases) obtained a descriptive histopathologic report. Of the cases with conclusive histopathological diagnosis, 58% were women, 31% were men and 11% did not inform their sex. The mean age of the studied population was 50.63 years and in 58% of the cases the patients had light skin. The largest number of lesions were from non-neoplastic proliferative processes, and the inflammatory fibrous hyperplasia (30.1%) was the most prevalent. Conclusion: the epidemiologic profile of patients attended during the study period consisted predominantly of women over 50 years of age and the most prevalent oral injury was inflammatory fibrous hyperplasia. This study reinforces the importance of the histopathological analysis as a diagnostic auxiliary method that enables the elaboration of specific strategies for prevention and early detection of the most frequent oral diseases in the population
