Gingival grafting
Depending on the shape of the gum recession and the levels of bone around the teeth, areas of gum recession can be regenerated with new gum tissue using a variety of gum grafting "periodontal plastic surgery" procedures performed by a specialist in periodontics (a periodontist). These procedures are typically completed under local anesthesia with or without conscious sedation, as the patient prefers. This may involve repositioning of adjacent gum tissue to cover the recession (called a pedicle graft) or use of a free graft of gingival or connective tissue from the roof of the mouth (called a free gingival graft or a subepithelial connective tissue graft). Alternatively, a material called acellular dermal matrix (processed donated human skin allograft) may be used instead of tissue from the patients own palate. Growth-factor techniques
Recent advances have seen the introduction of platelet-derived growth factor (PDGF) infused bone graft material. This material is usually combined with the cellular matrix to form a soft bone paste that is then covered by the allograft. The development of this type of bone and tissue cellular matrix (also known as ortho filler) results in greater osseointegration with the patients healthy bone and soft tissue. Healing from such procedures requires 2–4 weeks. After a few months the results can be evaluated and in some cases the new tissue needs to be reshaped in a very minor procedure to get an optimal result. In cases where recession is not accompanied by periodontal bone loss, complete or near complete coverage of the recession area is achievable.
Hutchinsons triad is named after Sir Jonathan Hutchinson (1828–1913). It is a common pattern of presentation for congenital syphilis, and consists of three phenomena:  interstitial keratitis, malformed teeth (Hutchinson incisors and mulberry molars), and eighth nerve deafness. There may also be a deformity on the nose known as saddle nose deformity. == References ==
