Parafunction
Abnormal function, as in bruxism or clenching, disordered or perverted function.

Paracrine
Transfer of chemical compounds such as hormones and growth factors from cell to cell. The hormone secreted by one cell is transmitted a very short distance to the cell it affects. Usually these cells are adjacent to each other. Messenger or hormone from other than an endocrine gland; in paracrine communication, products of cells diffuse…

Paracrestal incision
A crestal incision made away from the middle of the crest of an edentulous ridge, either buccally or lingually.
-
Paracervical saucerization
Progressive bone resorption occurring around the cervical portion of implants. Plausible etiologic factors can include surgical trauma, periimplantitis, occlusal overload, microgap, implant crest module, and compromise of the biologic width. Also, the excavation of tissue to form a shallow shelving depression, usually to facilitate drainage from infected areas of bone. Called also craterization.

Papule
A small, superficial, circumscribed, hard elevation of the skin that does not contain pus. A small, solid, usually inflammatory elevation of the skin that does not contain pus. Red, raised area of the skin, generally small and solid. A circular area on the skin that is reddened and elevated. A small coloured spot raised above…

Papillon–Lefevre syndrome
Palmarplantar hyperorthokeratosis with precocious periodontal destruction in the primary and permanent dentition. Thought to be the result of homozygosity of autosomal recessive genes. Papillon–Lefevre syndrome is an uncommon genetic condition that impacts the skin and gums. It leads to regions of dense, fissured skin. Furthermore, from an early age, the gums become susceptible to infections.…

Papilloma
A benign epithelial, exophytic, pedunculated, cauliflower‐like neoplasm. Viral etiology may be the causative agent. A benign epithelial tumour growing outwardly like in finger-like fronds. Wart or polyp; a benign growth in the epithelium. Any wart-like growth of the skin or mucous membrane. A benign tumour on the skin or mucous membrane. Benign growth on the…

Papillectomy
Surgical removal of a gingival papilla.
-
Papilla‐sparing incision
Incision that does not include the papilla and thus avoids the elevation of these tissues.
-
Papilla regeneration
Creating a papilla between an implant and an adjacent tooth or between adjacent implants. This may involve surgical procedures using small rotational pedicle flaps, use of connective tissue grafts, and/or prosthetic techniques to condition periimplant soft tissues. The term is a misnomer, since the papillae flatten in the edentulous space following tooth extraction once the…
