| guided tissue regeneration | The repopulating of the periodontium, after treatment for periodontal disease. Repopulation is achieved by guiding the periodontal ligament progenitor cells to reproduce in the desired location by blocking contact of epithelial and gingival connective tissues with the root during healing. This blocking is accomplished by using synthetic membranes or collagen membranes. (12 Dec 1998) |

| ultrasound guided biopsy | <procedure> The use of ultrasound to guide a biopsy needle to obtain a sample of tissue for analysis by a pathologist. (09 Oct 1997) |
| aberrant regeneration | Misdirected regrowth of nerve fibres seen for example, after oculomotor nerve injury. Synonym: misdirection phenomenon. (05 Mar 2000) |
| bone regeneration | Renewal or repair of lost bone tissue. It excludes callus formed after bone fracture but not yet replaced by hard bone. (12 Dec 1998) |

| regeneration harvest | A timber harvest method that removes selected trees in the existing stand to a density that allows for the establishment of a new even-aged stand below. (05 Dec 1998) |
| regeneration with reserves | Similar to a regeneration harvest, except that a number of green trees are left standing to meet other resource needs such as wildlife habitat. The number of trees left is usually specified as a certain number of trees per acre. (05 Dec 1998) |
| coppice regeneration | The ability of certain hardwood species to regenerate by producing multiple new shoots from a stump left after harvest. (05 Dec 1998) |

| periodontal | <dentistry> Pertaining to your gums. For example periodontal disease is gum disease. (08 Jan 1998) |
| periodontal abscess | Localised circumscribed purulent area of inflammation in the periodontal tissue. It is a derivative of marginal periodontitis and commonly associated with suprabony and infrabony pockets and interradicular involvements, in contrast to periapical abscess which is attributable to pulp necrosis. (12 Dec 1998) |
| periodontal anaesthesia | Anaesthesia of the periodontal ligament, produced by injection of a local anaesthetic drug. (05 Mar 2000) |
