| Abstract | ||
| Introduction: Soft lining material enhance the patient’s comfort, its rough surface affect oral health, the risk with soft reliners was difficult hygienic maintenance, sterilization by microwave method more favor compared with chemicals disinfections. Objective to study the effect of disinfection by microwave irradiation at different exposure time on surface roughness of long-term soft-liner material. Material and Methods: 45 Specimens of long-term soft liner were made in the form of square metal shaped pattern. The preparation of mould was done by conventional procedures according to manufacture instruction and divided into three groups: GroupA control (without disinfection), Group B daily disinfection by microwave for 5min at 650W and GroupC daily disinfection by microwave for15min at 650W. The specimens were irradiated daily for 15 days (both group B&C). Roughness measurement were made for three groups by profilometer device and analyzed by ANOVA ‘test. Result show that high mean value surface roughness of long term soft liner after expose to microwave disinfection for 15 min(Group C), and low mean value before expose to microwave disinfection(Group A), there were highly significant differences (P<0.01) among tested groups and there was no significance difference (p>0.05) between control Group with (Group B) 5 min disinfection, while the difference was significance (p<0.05) between (Group C )15 min disinfection with : (Group B) 5 min disinfection and with(Group A )control group. Conclusions: the roughness of longterm soft-liner material was not adversely affected by microwave disinfection at 5 min, there was no significant differences with control group while adversely affected by microwave disinfection at 15 min, there was significant differences with control group also with group 5 min disinfection. | ||
