Dental management prior to radiation therapy in patients with head and neck cancer.

Introduction: Patients diagnosed with head and neck tumors, are treated by surgery, radiation therapy (RT), chemotherapy (CT) or a combination thereof. The goal is to describe the management protocol for patients subjected to radiation therapy (RT) and to study their long-term oral health status.

Materials And Methods: A retrospective study was performed in a sample of 50 patients.

p21{Waf1/CIP1} is a poor diagnostic and prognostic marker for OSCC although its expression increases in patients with N1 regional metastasis.

Objectives: Downregulation of p21{Waf1/CIP1} (a cyclin-dependent kinase inhibitor) has been reported for mouth cancer. The goal of this article is to quantitatively report expression of p21{Waf1/CIP1} and evaluate its relationship with the clinical and prognostic factors.

Materials And Methods: this is a retrospective study of 68 patients diagnosed with OSCC.

Diode laser (980 nm) as adjunct to scaling and root planing.

Objective: The aim of this study was to evaluate clinical efficacy of InGaAsP diode laser as adjunct to traditional scaling and root planing.

Background Data: The use of laser is one of the most recent methods in nonsurgical periodontal treatment. Efficacy and side effects of each type of laser treatment have yet to be determined.
