Gene therapy is a field of Biomedicine. With the advent of gene therapy in dentistry, significant progress has been made in the control of periodontal diseases and reconstruction of dento-alveolar apparatus.Implementation in periodontics include:-As a mode of tissue engineering with three approaches: cell, protein-based and gene delivery approach.-Genetic approach to Biofilm Antibiotic Resistance.Future strategies of gene therapy in preventing periodontal diseases:-Enhances host defense mechanism against infection by transfecting host cells with an antimicrobial peptide protein-encoding gene.-Periodontal vaccination.Gene therapy is one of the recent entrants and its applications in the field of periodontics are reviewed in general here.
Periodontal dressing is a surgical dressing used post operatively to cover and protect the surface of surgical wound created by periodontal therapy.The sequelae of periodontal surgery are commonly pain, swelling, inflammation and bleeding and thus, many periodontists advocate that some form of protection should be applied over the injurious tissue so that the affected area is shielded from further insult 1. Prior to introduction of the first periodontal pack by Dr. AW Ward in 1923 3 , surgical eradication of periodontal disease was accompanied by the undesirable sequelae like pain, hemorrhage, unsatisfactory control of granulation tissue and sloughing. fig 1 Thus, s it can be concluded that wound protection, patient's comfort and some degree of hemostasis and tissue stasis are considered to be desirable effects in dressings. Zinc oxide Eugenol Dressing (Hard pack) Non-Eugenol Dressing (Soft pack) Other types are as follows; Collagen materials. Methacrylate gels. Light cure dressing. Cyanoacrylate. Oral adhesive bandage Wax pack.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
