ABSTRACT
: To evaluate the application of medical magnifying loupes in diagnosis of oral mucosal diseases. Twenty-four patients with plaque-type oral lichen planus or homogeneous oral leukoplakia were inspected by naked eyes or assistance with magnifying loupes. Histopathological results were used as the gold standard to evaluate the sensitivity, specificity and accuracy of the two methods in clinical diagnosis. Questionnaires were used to evaluate the subjective effect of magnifying loupes on the diagnosis efficiency of oral mucosal diseases and to explore the most suitable parameters for application. The sensitivity, specificity and accuracy of medical magnifying loupes for the identification of plaque-type oral lichen planus and homogeneous oral leukoplakia were 94.74%, 100.00% and 95.83%, respectively, which were significantly higher than those of naked eye inspection (89.47%, 80.00% and 87.50%). The effective rate of magnifying loupes assisted diagnosis was 91.76% according to physicians' subjective evaluation. The most suitable parameters were 3.5 times magnification and working distance. The medical magnifying loupes can effectively improve the efficiency of the inspection and diagnosis of oral mucosal diseases, and have the characteristics of convenience and real-time. The recommended clinical parameters are 3.5 times magnification and working distance.

Helicobacter pylori (Hp) is a Gram-negative bacterium selectively colonized in gastric mucosa, and is one of the main factors inducing chronic gastritis and even gastric cancer. Recent studies have shown that Hp infection induces various stress responses, including oxidative stress, nitrosative stress and endoplasmic reticulum stress. Hp can stimulate neutrophils, macrophages and gastric epithelial cells to express reactive oxygen species and reactive nitrogen species, resulting in excessive accumulation of reactive oxygen species and reactive nitrogen species, aggravating inflammation and damage to gastric mucosa. Such long-term inflammation and oxidative stress may increase the risk of cancer. In addition, Hp induced endoplasmic reticulum stress plays an important role in the early stages of precancerous lesion formation. This article reviewed the research progress of role of stress response induced by Hp infection in gastric mucosal diseases.
ABSTRACT
Corona Virus Disease 2019 (COVID-19) has broke out in 29 countries and regions in the world in a short period since December 2019. Various measures of prevention and control have been taken all over China. At present, the epidemic situation shows a positive trend, however, there are still a few new comfirmed cases in some area of China. So the job and thinking of epidemic prevention still cannot be relaxed. As an important specialty of stomatology, the risk of cross infection is high in oral medicine. Establishing an effective system of pre- inspection and triage and adopting strict measures of prevention and control are essential. According to the prevention and control situation of COVID- 19, the characteristics of hospital infection, pre examination, protective measures, the home management strategies of oral mucosal diseases during the epidemic period and the differential diagnosis between COVID-19 and common oral muco- sal diseases with fever were summarized and recommended in this paper.
ABSTRACT
Objective@#To investigate the prevalence of oral mucosal diseases (OMD) in patients with cerebrovascular disease.@*Methods@#A total of 182 patients with cerebrovascular disease and 166 controls were examined for OMD to compare the differences of prevalence rates.@*Results@#The prevalence of OMD in patients with cerebrovascular disease appeared higher than that in the control group. Oral candidiasis was most commonly seen (11.1%, 20/182), followed by fissured tongue (5.0%, 9/182), traumatic ulcer (2.8%, 5/182), herpes labialis (2.2%, 4/182), recurrent oral ulcer (1.6%, 3/182), chronic cheilitis (1.6%, 3/182) and oral leukokeratosis (1.6%, 3/182).@*Conclusion@#Patients with cerebrovascular diseases were susceptible to OMDs, especially to oral candidiasis that called for more attention.
ABSTRACT
El objetivo de esta comunicación es divulgar el uso de las placas de protectoras de mucosa (PPM) en el ámbito de la patología bucal, así como en la consulta odontológica diaria. Tomando como antecedente los primitivos protectores bucales diseñados para deportes de contacto, se desarrolló su uso en odontología con un diseño particular para el tratamiento de los desórdenes temporomandibulares. Describimos aquí la aplicación de las PPM en estomatología en el contexto de coadyuvancia terapéutica para diferentes entidades de muy frecuente consulta. Asimismo, se detallan la técnica de confección y las indicaciones de uso y cuidado para los pacientes (AU)
The aim of this report is to emphasize the usefulness of oral splints for mucosa protection in oral pathology as well as in every day dental practice. There is substantial evidence that mouthguards were first developed for use in boxing. The most common therapeutic use of occlusal splints in dentistry is the treatment of temporomandibular joint disorders. The present work describes the use of oral splints for mucosa protection in the context of adjuvant therapy as a protective device for many common disorders of the oral mucosa. At the same time it explains the fabrication technique and provides proper use and handling guidelines (AU)

Holistic integrative medicine (HIM), as one of the important ideas in the field of medicine, arouses great concern recently. HIM regards the human body as a whole, turns data and evidence in medical research back to facts, integrates technologies and experience developed in clinical research into medical skills. The repeated practices at the levels of fact, experience, and medical skills will generate true knowledge to solve the wide spread problems brought by linearized thinking and fragmented knowledge. With the development of highly divided medical disciplines, how to utilize and practice HIM has become a common concern of the medical community. Specialization of stomatology, which is a first level discipline like medicine, has also become a trend for years. However, holistic concept cannot be overlooked, especially in the development of oral medicine. This article aims at the communication and exchange of knowledge about HIM among dental professionals. In order to serve the patients better, the authors look forward to practicing the HIM concept in the field of oral medicine through the efforts of us all.
ABSTRACT
As a new technique, photedynamic therapy was introduced in the end of 1970s and has been put into clinical application from experimental tests in recent years. Its mechanisms was established on the basis that a series of special typed cells and tissues could selectively absorb photosensitive drugs and generate photore-sponsive effects by light irradiation of definite wavelengths. Currently, the photodynamic theraputics is applied mainly in non surgical treatment of tumor betided in body superfacial and hollow viscus. Its application area has been expanded unceasingly in modern clinic due to the discovery of the selective aggregation of photoresponsive drugs to many pathological tissues and pathogenic microorganisms other than tumors, and the development of new photoresensitizer. In this paper, review is given on the effect mechanisms, the light sources and photosensitizer, as well as the application of photodynamic treatment of tumors in head and neck and its treatments of mucosal dis-ease and oral pathogenic microorganism infected diseases.
