Comparative Study Of Retention Of Palate-Less Versus Complete Palatal Coverage Dentures Fitted With Zirconia Mucosal Inserts, Fardos N. Rizk
Comparative Study Of Retention Of Palate-Less Versus Complete Palatal Coverage Dentures Fitted With Zirconia Mucosal Inserts, Fardos N. Rizk
Dentistry
Objective: The purpose of this study is to compare the retention of palate-less versus complete palatal coverage dentures fitted with zirconia mucosal inserts. Materials and Methods: Fourteen male patients received upper complete dentures fitted with zirconia mucosal inserts. Half of the dentures were fabricated with complete palatal coverage (Group I) and the other half was palate-less (Group II).Retention was measured for all patients using force measurement gauge through six months follow-up period. Results: Both groups showed increase in denture retention through the follow-up period however, dentures with complete palatal coverage (Group 1) showed higher mean values of retention compared to …
Comparative Study Of Implant Stability And Bone Height Changes Among Different Implant Designs Retaining Partial Overdenture, Fardos N. Rizk
Comparative Study Of Implant Stability And Bone Height Changes Among Different Implant Designs Retaining Partial Overdenture, Fardos N. Rizk
Dentistry
Objective: This study was conducted to assess the primary stability of Trabecular Metal Dental Implant and Tapered Screw Vent Implant to determine the appropriate time for their loading by lower partial overdenture and to follow up for one year the changes in implant stability and crestal bone height surrounding the implant after loading it. Materials and Methods: The study was performed on ten lower Kennedy class I partially edentulous male patients. Each patient received one implant at the second molar area in each side of the ridge, where Trabecular Metal Dental Implant was inserted in the left side of the …

Immunohistochemical Assessment Of Cytokeratin 17 And Epcam Expression In Different Grades Of Oral Squamous Cell Carcinoma, Safaa El-Baz, Iman Helmy, Mohamed Hosam El Mallahy

Oral squamous cell carcinoma (OSCC), one of the most common malignancies in the head and neck region, is graded based on Broder’s classification into well-differentiated, moderately, and poorly differentiated. Cytokeratin 17 (K17, CK17) is an acid-type I cytokeratin with a low-molecular weight of 48.1 kDa. Epithelial cell adhesion molecule (EpCAM) is a hemophilic Ca2+ independent adhesion molecule. This study used an immunohistochemical technique (IHC) to examine the expression of CK17 and EpCAM in thirty-two specimens of OSCC (comprising 13 well-, 9 moderately, and 10 poorly differentiated cases), and 2 specimens of normal oral mucosa, used as control. It was found …
