Oral cancer on the gingiva in patients with proliferative leukoplakia: A study of 30 cases.

Background: Proliferative verrucous leukoplakia, recently coined as proliferative leukoplakia (PL), is associated with a strong tendency to recur after treatment and an elevated rate of malignant transformation. We compared the clinical characteristics of patients with gingival PL with and without progression to oral squamous cell carcinoma.

Methods: The patients were divided into two groups: group 1 included 33 patients with gingival PL that did not progress to cancer, and group 2 included 30 patients with PL who developed malignant transformation during follow-up.

Comparative split-mouth study of the anesthetic efficacy of 4% articaine versus 0.5% bupivacaine in impacted mandibular third molar extraction.

Objective: The purpose of this study was to compare the clinical efficacy of articaine at 4% (epinephrine 1:100,000) with bupivacaine at 0.5% (epinephrine 1:200,000) for surgical extraction of impacted mandibular third molars.

Study Design: This was a randomized, double blind, split-mouth, clinical trial.

Alcohol sclerotherapy to treat vascular malformations in the oral cavity.

Objective: To present our experience in treating vascular malformations in the oral cavity solely by injecting ethanol into the lesions.

Material And Methods: We treated 26 patients (12 men and 14 women) with oral malformations. The diagnosis was based on clinical findings (n=26), magnetic resonance imaging studies (n=19), angiography findings (n=5), and direct puncture venography (n=2).

Malignant transformation of proliferative verrucous leukoplakia to oral squamous cell carcinoma: a series of 55 cases.

In this study, we compared clinical differences between patients with proliferative verrucous leukoplakia (PVL) who did and did not develop oral cancer. This was a retrospective study of 55 PVL cases. All patients were followed for at least 1year, with a mean follow-up of 7.

Foreign body granulomatous reactions to cosmetic fillers: a clinical study of 15 cases.

Introduction: Subcutaneous or submucosal infiltration of cosmetic materials is a very common practice, because of the ease with which such materials can be deposited, and their presumed innocuousness. However, in recent years there have been reports of foreign body granulomatous reactions occurring many years after infiltration.

Method: Data were collected on the clinical manifestations, histopathological findings, treatment, and course of the lesions of 15 patients.
