Evaluation effects of povidone iodine on some mechanical properties of soft liner materials
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 10
Abstract
*Statement of problem:-soft denture lining materials has a key role in modern prosthodontics because of their capability of restoring health of inflamed and distorted mucosa, and the patients suffer from the injury , fungal or bacterial after maxillo facial surgery also the patient needed obturator prosthesis after postsurgery in the mouth . *Purpose of this study :- Evaluate the effect of incorporated povidone iodine in different volum into acrylic soft denture liner and to assessment the effect of this addition on some mechanical and physical properties . *Materials and methods:-Atotal of 200 specimens were prepared from acrylic soft liner material incorporated into three volum (0.05ml,0.1ml and 0.2ml),and divided into five groups according to each conducting test(tensile strength,hardness,compressive strength ,absorption and solubility and color change) with 40 specimens for each test,then each group subdivided into :- * Control group consist 10 specimens for each test without any additions. *Experimental groups :contain thirty specimens after incorporated with povidone iodine (0.05ml,0.1ml and 0.2ml) 10 specimens for each volum. *Results :-The results of this study showed that the highly significant decrease in the tensile strength and hardness for all volum,and highly significant increase the compressive strength and color change for all volum,also significant increase by 0.05ml and 0.1ml water sorption and 0.2ml water solubility after incorporated soft liner material with povidone iodine . *Conclusions: - The incorporation of the povidone iodine effects on some properties of the soft lining material (tensile strength ,hardness,compressivestrength, water sorption and solubility and color change).
