Is focal melanotic lesion potentially malignant? A case report.

Malignant melanoma is a lesion of melanocytes that is commonly observed on cutaneous surfaces. In 35-50% of cases, it originates from a pigmented precursor. Although oral melanocytic pigmentation is very common, melanocytic malignancies such as melanoma, are rare.

A relationship between salivary flow rates and Candida counts in patients with xerostomia.

Context: Most of the adult population is colonized by Candida in their oral cavity. The process of colonization depends on several factors, including the interaction between Candida and salivary proteins. Therefore, salivary gland hypofunction may alter the oral microbiota and increase the risk for opportunistic infections, such as candidiasis.

Comparison of chemiluminescence and toluidine blue in the diagnosis of dysplasia in leukoplakia: a cross-sectional study.

Aims: The early diagnosis and treatment of oral cancer at a potentially-malignant stage would reduce morbidity and improve the survival rates and quality of life of patients. Leukoplakia is the most common potentially-malignant disorder. Clinical examination alone cannot differentiate between dysplastic and non-dysplastic leukoplakia.
