The goal of periodontal therapy remains to provide a dentition that functions in health and comfort for the life of the patient. Studies determining long-term tooth loss in periodontally treated patients demonstrate that, for the majority of periodontal patients, this goal is a reality.
Periodontal therapy involves two primary components. First elimination of the periodontal infection, by eliminating the pathogenic periodontal microflora, which induces substantial favorable clinical changes in the periodontium. However, the anatomic defect resulting from active periodontitis still persists and is represented clinically by loss of clinical attachment, increased probing depths, and radiographic bone loss. The substantial efforts made to alter this defect represent the second component of periodontal therapy.
Regenerative treatment has as its goal elimination of periodontal defects by regenerating the lost periodontium including bone, cementum, and periodontal ligament. A number of therapies such as implantation of autografts, allografts and alloplastic materials, chemical root conditioning, growth factors, guided tissue regeneration, platelet rich plasma and combination of these have been used in clinical practice to reconstruct the periodontal tissues. Also, traditional herbal products like those derived from plants have been used and evaluated for being used in modern medicine.8
Medicinal plant is any plant which in one or more of its organ contains substance that can be used for therapeutic purpose or which is a precursor for synthesis of useful drugs (According to WHO). Medicines are prepared from variety of plant materials like leaves, stems, root, barks and so on. They mainly contain biologically active ingredients and are used primarily for treating mild or chronic ailments.
Herbs can be prepared at homes in many ways using either fresh or dried ingredient example : roots, bark or other plant parts can be boiled into strong solutions called “Decoctions” then honey and sugar can be added to infusions and decoctions to make syrups. Now herbal medicines can also prepared in the form of pills, capsules or powders or in more concentrated liquid form called extracts and tinctures, they can also be applied topically in creams or ointments or applied directly to the skin as poultices.8
Cissus quadrangularis, a perennial climber widely used in traditional medicinal systems of India has been reported to possess bone fracture healing, antibacterial, antifungal, antioxidant, anthelmintic, antihemorrhoidal and analgesic activities.
