Purpose: To determine whether the treatment of oral leukoplakia with potassium-titanyl-phosphate (KTP) lasers versus CO(2) lasers results in lower recurrence rates.
Materials And Methods: Retrospective data were collected from the records of 30 patients (mean age 75.6 years) with 35 primary oral leukoplakia who had their lesions ablated by KTP laser, and 45 patients (mean age 59.9 years) with 59 primary oral leukoplakia who had CO(2) laser treatment. The recurrence rates of lesions between these 2 groups was then compared.
Results: A statistically significant (P = .049) reduction in recurrence rates for those patients treated with KTP lasers versus CO(2) lasers was found.
Conclusion: The use of KTP lasers for the treatment of oral leukoplakia may result in lower recurrence rates than when using CO(2) lasers.

Statement Of The Problem: Oral squamous cell carcinoma (OSCC) is the most common type of oral cancer. During the invasion, tumour cells break through the basement membrane and penetrate the connective tissue to interact with the extracellular matrix. An attempt was made to evaluate the connective tissue changes in different grades of OSCCs, oral submucous fibrosis (OSMF) and Oral Epithelial Dysplasias.

The study aimed to investigate oral potentially malignant disorders (OPMDs) diagnosed in an Oral Pathology service in southern Brazil over a span of 56 years and to assess the factors influencing their severity and outcomes. A retrospective analysis of histopathological records from 1965 to 2021 was performed. Lesions diagnosed as leukoplakia, erythroplakia, leukoerythroplakia, or actinic cheilitis were included.

Oral potentially malignant disorders (OPMD) are a group of lesions carrying the risk of developing into cancer. The gold standard to predict which lesions are more likely to undergo malignant transformation is the presence of dysplasia histologically. However, not all dysplastic lesions progress, and non-dysplastic lesions may also undergo malignant transformation.
