Psychological disorders and quality of life in oral lichen planus patients and a control group.

Objectives: Oral lichen planus (OLP) is a common disease whose aetiopathogenesis is linked to psychological disorders. This study aims to determine the influence of anxiety and depression in OLP patients, define the perception of quality of life in these patients and check for potential differences between atrophic/ ulcerative and reticular lesions.

Materials And Methods: A group of 48 OLP patients and a control group of 40 patients were selected.

Oral lichen planus and its relationship with systemic diseases. A review of evidence.

Background: Oral lichen planus (OLP) is one of the most common dermatological diseases which are present in the oral cavity. It is a chronic autoimmune, mucocutaneous disease that affects the oral mucosa as well as the skin, genital mucosa and other sites.

Objective: Review the relevant information to OLP and its relationship with systemic diseases.

Lichen planus and diabetes mellitus: Systematic review and meta-analysis.

Objective: The aim of this study was to perform a systematic review and meta-analysis answering the following questions: (a) "What is the prevalence and risk of oral lichen planus among patients with diabetes mellitus?" and (b) "What is the prevalence and risk of diabetes mellitus among patients with oral lichen planus?".

Material And Methods: A bibliographic search was conducted in PubMed/Medline and Scopus database from 1966 to March 2018, using the following terms: "Lichen planus" AND "Diabetes mellitus" AND "Prevalence" AND "Oral mucosal lesions".

Results: Twenty-two studies were included in this review.

Knowledge About the Relation Between Tobacco and Disease and the Attitude Toward Advising the Cessation of Its Consumption Among a Group of Spanish Dental Students.

Tobacco is one of the leading causes of preventable death in the developed world. Smoking is associated with a large number of oral pathologies, such as cancer and periodontitis. Dental professionals can play a key role in preventing these health problems.

Clinical value of diascopy and other non-invasive techniques on differential diagnosis algorithms of oral pigmentations: A systematic review.

Objectives: To determine the diagnostic value of diascopy and other non-invasive clinical aids on recent differential diagnosis algorithms of oral mucosal pigmentations affecting subjects of any age.

Material And Methods: Data Sources: this systematic review was conducted by searching PubMed, Scopus, Dentistry & Oral Sciences Source and the Cochrane Library (2000-2015); Study Selection: two reviewers independently selected all types of English articles describing differential diagnosis algorithms of oral pigmentations and checked the references of finally included papers; Data Extraction: one reviewer performed the data extraction and quality assessment based on previously defined fields while the other reviewer checked their validity.

Results: Data Synthesis: eight narrative reviews and one single case report met the inclusion criteria.

Malignant transformation of oral lichen planus by a chronic inflammatory process. Use of topical corticosteroids to prevent this progression?

Background: Oral lichen planus is a potentially malignant disorder with a capacity, although low, for malignant transformation. Of all the factors related to the process of malignant transformation, it is believed that the chronic inflammatory process plays a key role in the development of oral cancer. This inflammatory process is capable of providing a microenvironment based on different inflammatory cells and molecules that affect cellular growth, proliferation and differentiation.

Intracellular pH regulation in oral squamous cell carcinoma is mediated by increased V-ATPase activity via over-expression of the ATP6V1C1 gene.

Oral squamous cell carcinomas represent more than 90% of all head and neck cancers, and comprise about 4% of all malignancies in western countries. Tumor cell mobility related to increasing intracellular pH results in impaired proliferation and metastasis, suggesting an important role of pH regulation in solid cancer tumorigenesis. The mechanism of physiological pH regulation has been shown to be activated in several solid tumors through constitutive activation of the ATPase complex.
