| Abstract | ||
| Denture stomatitis is a disease associated with colonization of Candida albicans on a denture surface. In a review of literature, a variety of topics used for the management of this case. And this especially include: systemic drug, treatment with chemical disinfectant or irradiation of denture with plasma. With the introduction of laser and its several applications in medicine and dentistry .the present study used Nd: YAG laser for this purpose. The present study evaluates the effect of diode pumped Nd: YAG laser (second Harmonic generation) on adherent Candida albicans on the surface specimen and other properties of heat cure acrylic including (Transvers strength, Impact strength, surface roughness surface hardness and FTIR test). Diode pumped Nd:YAG laser type second harmonic generation have wave length532nm&power 1watt were used.Specimens were made from heat cure denture base material .Evaluation the properties of this material has been done before and after laser irradiation of the specimens for 5&10 min. The distance between the source of laser and specimens was 100cm .All data analyzed with the use of statistical test (X ≤0.05). Results ofirradiation of heat cure specimens with Nd:YAG laser revealed a lower mean values (M=66.1,SD=11.779,M=0.753,SD=0.415)for transvers strength &surface roughness respectively at 10min.At the same time, the results appeared the highest mean values(M-80.20,SD=11.3,M=6.21,SD=1.324)for indentation hardness and impact strength respectively.Nd:YAG laser irradiation to heat cure specimens showed a decrease in the mean value of Candida albicans adherence test for two time:10&5min with statistically no significant difference at a level of (p≤0.05). According to the results of the present study it can be concluded that Nd: YAG laser can be used for the reduction of Candida albicans adherence to heat cure with minimal adverse effect on someother properties of material tested. | ||
