An In Vitro Evaluation Of Microleakage In Class V Preparations Restored With Hybrid Versus Silorane Composites., Fahad Umer, Farah Naz Farid, Farhan Raza Khan

Section of Dental-Oral Maxillofacial Surgery

Aim: To compare the difference in microleakage values using conventional and new low-shrink Silorane composites using the dye penetration method. Background: With improvement in adhesive technology, problems associated with composites have been largely overcome. However, microleakage due to polymerization shrinkage still remains a challenge. New Silorane-based composites are alleged to have less than 1% polymerization shrinkage, which would potentially decrease the microleakage, and hence, resolve this longstanding issue. Materials And Methods: The teeth were randomly divided into three groups (A,B, and C). Group A was restored with conventional composite (Valux() Plus), with a total-etch protocol, Group B was restored with …

Porcelain Fused To Metal (Pfm) Crowns And Caries In Adjacent Teeth, Durr-E-Sadaf, Zubair Ahmad

Section of Dental-Oral Maxillofacial Surgery

OBJECTIVE: To assess the discrepancies in marginal integrity and contact points of Porcelain Fused to Metal (PFM) crowns and its association with caries in adjacent teeth.

STUDY DESIGN: Cross-sectional study.

PLACE AND DURATION OF STUDY: Dental Section of the Aga Khan University Hospital, Karachi, from January to August 2009.

METHODOLOGY: Ninety six (96) patients with PFM crowns on maxillary and mandibular premolars and molars were included in this study. Single unit PFM crowns that were part of fixed bridge with at least one natural adjacent tooth were studied. PFM crown with no adjacent tooth or badly broken down teeth were …
