In today's time, the key to achieve the successful restoration is the selection of the proper dental cement. The proper selection of the dental cement ultimately increases the survival rate of the prosthesis or the restoration. From the past few years many new dental cements recently developed and claims better properties as compared to the traditional cements.

Platelet rich fibrin is a part of platelet concentrate, that is derived from human blood and made through the process of centrifugation. It is an autogeneous bio material, which basically constitutes various growth factors, and cytokines that are entrapped in its matrix of fibrin. Platelet rich fibrin provides ideal environment for healing of the wound and the regeneration of the tissue. Platelet rich fibrin helps in regulating the inflammation process and increases the healing process.

Temporomandibular disorders usually represented as a group of painful as well as altered conditions involving the muscles of mastication and the muscles around the temporomandibular joint. Usually the patient are un aware of the condition. Temporomandibular joint disorders affects twenty five percent of the population. Temporomandibular disorders represent with musculoskeletal degenerative conditions of the joint which results in functional as well as morphological deformities of the temporomandibular joint. As temporomandibular disorders cases are complex with unique nature with respect to each case, so the diagnosis and treatment modality is quite different for each type of case.

For the better out come of the fixed dental prosthesis in terms of periodontal health, in terms of aesthetics and longevity of the prosthesis, a good and proper retraction of the gingival tissue is very much required. For the proper placement of the fixed dental prosthesis over the prepared tooth requires close contact with the adjacent tissue i.e. gingiva, so for the proper and placement of the prosthesis in the close proximity requires adequate isolation and retraction of the soft tissue around the prepared tooth. For the procedure of gingival retraction various methods and different materials are available.
