|Periodontitis||Device: Zirconia crown Device: Porcelain metal crown||Not Applicable|
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.

Experimental: Z Crown
A Zirconia crown will be provided to patients.
Device: Zirconia crown
patients will receive a Zirconia crown, the Zirconia crown will cover the natural crown.
Active Comparator: PFM Crown
A Porcelain metal crown will provided to patients.
Device: Porcelain metal crown
patients will receive a porcelain fused to metal crown, the Porcelain metal crown will cover the natural crown.
- 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.
- PIaque index [ Time Frame: 4 months ]The clinical examination will include measurement of PIaque index( soft tissue deposite around teeth)
- GIingival index [ Time Frame: 4 months ]The clinical examination will include measurement of the GIingival index (gingival inflamation around teeth)
- Pocket depth [ Time Frame: 4 months ]The clinical examination will include measurement of Pocket depth around teeth
- Clinical attachment level [ Time Frame: 4 months ]The clinical examination will include measurement of the Clinical attachment level around teeth
- bone level [ Time Frame: 4 months ]Periapical radiography will be obtain using customized film holding with Vinylpolysiloxan bite registration. Measurements of alveolar bone level will be performed on the digital images by a single examiner, using custom-made software.
