Active clinical trials for "Oral Manifestations"

The oral cavity is particularly susceptible to viral infection with several viruses such as herpes simplex virus, cytomegalovirus and Zika virus because of its structures, especially salivary glands and soft tissues Moreover, oral mucosa can be affected by secondary pathological process of a bacterial or fungal nature due to viral immunosuppression. The oral cavity could be considered a "biological barometer" of both viral infection and viral immunosuppression advancement .

The SARS-Cov2 virus was identified in china at the end of 2019 and spread worldwide causing a global pandemic. Current research showed that SARS-Cov2 virus invades human cells via the receptor angiotensin-converting enzyme 2 (ACE2) through scRNA-seq data analyses. The study identified the organs that are at risk and are vulnerable to SARS-CoV-2 infection. Therefore, cells with ACE2 receptor distribution may become host cells for the virus and cause inflammatory response in related organs and tissues, such as the tongue mucosa and salivary glands. These results suggest that oral mucosa could be a target of SARS-CoV-2 infection

According to WHO Reportin 2002, iron deficiency anemia was considered to be the most important contributing factor to the global burden of anemia. Children and women in reproductive ages are more at risk factor for developing iron deficiency anemia.No previous study has been held to assess prevalence of oral manifestations of iron deficiency anemia as a hospital-based cross-sectional study on a sample of Egyptian patients in hematology department (no previous data recorded).

Hepatitis C virus (HCV) is the major cause of chronic liver disease and has a long-term resultant complications4 and it considered as a major endemic medical health problem in Egypt. It affects multiple organs and reflect various manifestations on oral cavity.The purpose of this study is to assess the prevalence of oral mucosa conditions, type of oral manifestation and gingival lesions in patients with hepatitis C

The purposes of this study are threefold: 1) to evaluate the prevalence and risks of oral complications in patients with aplastic anemia; 2) to evaluate if oral problems in these patients can predict their response to treatment; and 3) to review complications of dental treatment in these patients in order to establish treatment guidelines. This study will be performed through a review of medical charts of 79 patients with aplastic anemia and 67 patients with schizophrenia who were treated at the National Institutes of Health Dental Clinic between 1993 and 1999. The schizophrenia patients will serve as a control population. Demographic, clinical and radiographic information will be collected for all patients. Additional data collected only for aplastic anemia patients will include medical therapy, disease duration, blood cell counts, oral problems that developed during treatment and treatment response.

Attention-deficit/hyperactivity disorder is the most common childhood neuro-developmental disorder that is characterized by inattention, hyperactivity, and impulsivity. These symptoms last till adulthood in 65% of cases. ADHD has been reported to have a worldwide prevalence of 5.3% and it is more common in boys than in girls (Ghanizadeh 2008; Serra-Negra et al. 2012 and Shooshtari et al. 2013) The symptoms of ADHD are generally treated through behavioral therapy, with or without pharmacological intervention. Medications prescribed are commonly divided into stimulant or non-stimulant drugs. The stimulant medications (such as methylphenidate and amphetamines) have been implicated in adverse oral effects, such as xerostomia and gingival enlargement. The current evidence is controversial regarding the severity and prevalence of dental caries, dental trauma, periodontal diseases, oral habits and tooth wear among patients with ADHD (Chau et al. 2017). In the Arab world, few studies have been published on ADHD. Accordingly, in the Arab society and Egypt there are limited data regarding the oral findings of children with ADHD. Owing to the sparsity of these data, this study will be conducted to evaluate different oral characteristics of Egyptian children with ADHD.

This study is a multicenter cross-sectional survey-based study conducted in four European countries (Czech Republic, Germany, Slovak Republic, and Turkey). An online questionnaire will be utilized to collect data from volunteer subjects following the STROBE reporting guidelines of cross-sectional studies.

online questionnaire will be distributed in different country to detect the oral change in patient diagnosed with COVID-19

The oral manifestation of COVID 19 that could help in the diagnosis of patient
