Bacterial adhesion and microleakage of restorative materials for sealing accessory canals in implant prosthesis.

The level of bacterial adhesion and bacterial microleakage in four different materials utilised to seal the access passage of screw retained implant supported prosthesis (SRIP) is of interest to dentists. Four distinct categories were created from the samples on the basis of restorative materials used for sealing access passage in SRIP. Guttapercha and light cured acrylic resin were found to have comparatively low bacterial adhesion and bacterial microleakage in sealing accessory canals in screw retained implant supported prosthesis.

Analysis of salivary alpha-L-fucosidase and salic acid among oral sub-mucous fibrosis patients.

The salivary concentrations of alpha L fucosidase (AFU) and salic acid (SA) in oral submucous fibrosis patients and compare it with healthy controls is of interest to dentists. 40 patients of OSMF and 40 healthy controls were included. Estimation of AFU and SA in saliva and serum was carried out in every patient. The serum level of AFU was 37.4±26.8 in OSMF patients and saliva level of AFU was 35.4±14.5. The serum level of AFU was 19.2±4.3 in control group and saliva level of AFU was 35.4±14.5 in control group. The serum level of SA was 20.32±2.71 in OSMF patients and saliva level of SA was 18.21±2.40. The serum level of SA was 4.89 ±1.17 in control group and saliva level of SA was 3.13 ±1.04 in control group. Estimation of concentration of SA and AFU in saliva can be effective biomarker in diagnosis of OSMF.
