Overview
Brief Summary
Investigate the influence of the crown tye Porcelain fused to metal or Zirconia on periodontal health.
Detailed Description
Porcelain fused to metal (PFM) has been used in dentistry for the last five decades. Zirconia (zirconium oxide, ZrO2) is the white crystalline powder oxide of the naturally occurring metal zirconium. Research of the medical utilization of zirconia dates back to the late 1960s. However, its utilization in dentistry did not start until the 1990s, when zirconia began to be used as a form of endodontic posts and implant abutments. The current literature contains studies that investigated the influence of zirconia implants and abutments on periodontal tissue, but to the investigators' knowledge, no work has been yet published which compares the influences of crown types on hard and soft tissues. This prospective study will be conducted in the Department of Periodontology and in the Department of Maxillofacial Rehabilitation at Rambam Health Care Campus.

Outcomes
Primary Outcomes
PgE2 ( Prostaglandin E2)
Time Frame: 4 months
Gingival cervicular fluid samples will be attempt be planning Periotrom paper in the mesial and distal aspect of the experimental teeth. This samples will be assayed for PgE2 ( Prostaglandin E2) using Elyza kit. The concentration of PGE2 in gingival crevicular fluid will be examined around each tooth receiving a crown.
Secondary Outcomes
- bone level(4 months)
- Clinical attachment level(4 months)
- Pocket depth(4 months)
- PIaque index(4 months)
- GIingival index(4 months)
