Polyvinyl chloride (cordo) facial and body prostheses.

Protective effect of vitamin E on sperm quality and in vitro fertilizing potential and testosterone concentration in polyvinyl chloride treated Male rats

Polyvinyl chloride (PVC) has toxic effects through the induction of oxidative stress in the body and testicles. Vitamin E (Vit E) is a dietary compound that functions as an antioxidant scavenging toxic free radicals. The present study aimed to probe the protective effect of Vit E against PVC-induced reprotoxicity in male rats. In this experimental study, 24 male rats were randomly divided into ...

Prevention of Cutaneous Tissue Contracture During Removal of Craniofacial Implant Superstructures for CT and MRI Studies

OBJECTIVES Head and neck cancer patients who have lost facial parts following surgical intervention frequently require craniofacial implant retained facial prostheses for restoration. Many craniofacial implant patients require computed tomography and magnetic resonance imaging scans as part of their long-term follow-up care. Consequently removal of implant superstructures and peri-abutment tiss...

Stabilizing Effect of Organic Stabilizer (EDTA, 1,2 Propane diol, Benzoic Acid and Phenol) on the Thermal Degradation of Polyvinyl Chloride (PVC)

Candida biofilm formation on voice prostheses.

Laryngopharyngeal malignancy is treated with radiotherapy and/or surgery. When total laryngectomy is required, major laryngeal functions (phonation, airway control, swallowing and coughing) are affected. The insertion of a silicone rubber voice prosthesis in a surgically created tracheoesophageal puncture is the most effective method for voice rehabilitation. Silicone, as is the case with other...

Electrochemical Properties and Antibacterial Activity of Polyvinyl Chloride Supported Silver Molybdate Ion-Exchange Composite Membrane

Polyvinyl chloride supported silver molybdate composite material is used to develop by solution casting method. This membrane was characterized by various instrumental techniques such as Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) analyses. These characterizations are used to understand the functional groups,thermal sta...
