CLINICAL AND RADIOGRAPHICAL EVALUATION OF CALCIUM SULFATE HEMIHYDRATE AS A BONE SUBSTITUTE AROUND IMMEDIATE IMPLANT

Master Abstract

This study was carried out to evaluate single tooth replacement with dental implants inserted in to fresh extracted socket in single rooted mandibular teeth. Ten cases were participated in this study and was divided into two groups; group in which immediate implantation was done covered by MGCSH and the other without MGCSH. The surgical steps was based on careful and gentle handling of the tissue with minimal tissue damage in a clean and aseptic operating environment and a traumatic technique. Clinical evaluation was performed at 1,3 month after loading using the following clinical parameters : presence of pain, tenderness, infection, swelling, gingival index, probing pocket depth and mobility of implant. All patients recovered well after surgery, they showed no complications throughout the evaluation period. None of the cases showed any signs of pain, tenderness, infection or mobility throughout the study period. Differences in mean probing depth as well as in mean gingival index were statistically insignificant in all stages of follow up period neither within the same group nor between both groups. Radiographic evaluation was performed using standardized periapical radiographs to evaluate the surrounding bone at intervals 1,2,3,4,6 month after implant placement. Radiographic evaluation revealed no peri-implant radiolucency around all implants, and the marginal bone loss around the implant was minimal. The marginal bone height for both groups had increased significantly. Differences in the marginal bone height were insignificant as comparing the two groups. Furthermore, the peri-implant bone density for both groups showed a significant increase. Nevertheless, no significant difference was observed between the two studied groups.

ASSESSMENT OF PAROTID GLAND DUCTAL SYSTEM CHANGES IN DIABETIC PATIENTS USING DIAGNOSTIC SIALENDOSCOPY

PHD Abstract

Assessment of Parotid Gland Ductal System Changes in Diabetic Patients Using Diagnostic Sialendoscopy Xerostomia is a widely spread complaint in about 82.5% of uncontrolled type 2 diabetics. Although studies revealed parotid gland basement membrane abnormalities in diabetics, ductal system changes have not been described before. Hence, we present the first study to assess ductal changes in diabetics using sialendoscopy. Forty parotid glands in twenty patients ranging from 35 to 50 years were explored using diagnostic sialendoscopy. Patients were equally divided into: group I: uncontrolled diabetics and group II: healthy volunteers. Ductal changes were recorded in 3 distinct working zones and classified as: anatomic variations, inflammation, mucus plugs. Chi square test was used to compare groups whereas; Cochran's Q test was used to compare zones. Ductal abnormalities were significantly higher in diabetics when compared to healthy volunteers in nearly all 3 ductal zones. In diabetics, stenosis percentage was (55, 90, 100%) in zones 1, 2, 3 respectively. Conversely, it was (15, 20, 20%) in volunteers (P<0.01). Hyperemic changes in diabetics were (90, 90, 40%) compared to (10, 0, 0%) in volunteers (P<0.01). When comparing zones in diabetics it was found that stenosis increased significantly towards proximal end. Whereas, hyperemia prevailed towards distal end.
