What are 4 postop complications of mandibular canine tooth extraction? JVD Fall 2013 | loss of function, loss of mandibular strength=fx risk, iatrogenic mandibular fx, tongue protrusion |
What tissue has been used to reconstruct the rostral aspect of a dog's muzzle after traumatic amputation? Vet Surg 2013 | mucoperiosteum of the hard palate |
What effect does extraction of multiple contiguous teeth have on the alveolar ridge compared to when a single tooth is extracted? Clin Implant Dent Relat Res 2011 Dec | causes significantly more alveolar ridge bone loss |
What is the goal of periodontal flap sx? JVD Spring 2012 | to obtain new attachment with regeneration of periodontal tissues |
What are potential complications of perio flap sx? JVD Spring 2012 | healing with long junctional epithelium despite bone regeneration, perio pocket formation or recurrence, ankylosis with rot resorption, recurrence of gingival recession/attachment loss |

Which type of bone graft has the highest antigenic capacity? JVD Fall 2012 | xenograft (transferred to individual of unrelated species) |
What type of collagen plays an important role in osteoblastic differentiation (and their proliferation and bone deposition) Am J Orthod Dentofacial Orthop 2010 | Type I collagen |
What are the 4 phases of wound healing? Am J Orthod Dentofacial Orthop 2010 | inflammation, proliferation, tissue formation with contraction, and tissue remodeling |
What is the main reason that maxillary growth and dentoalveolar development are impaired after surgical closure of the palate in immature animals? Am J Orthod Dentofacial Orthop 2010 | Iatrogenic tissue disturbance (esp. periosteum) causes wound contraction and scar tissue formation |

What benefit does using microbial fiber membrane-Flagyl (MF-FLA) impart when placed over alveolus after tooth extraction? J oral maxillofac surg 2010 | hemostasis, facilitates growth of fibroblasts and osteoblasts, inhibits inflammatory cells = superior degree and rate of healing (compared to extraction sites w/o MF-FLA) |

What are Halstad's principles? | basic principles for aseptic surgery |
List the first 4 Halstad's principles | (1) apply strict asepis during prep and sx, (2) good hemostasis improves conditions for the procedure, limits infection, (3) avoid the formation of dead space, (4) minimize tissue trauma through careful handling |
List the last 3 (of 7) Halstad's principles | (5) maintain blood supply, (6) avoid undue tension on tissues, (7) carefully adapt the corresponding tissue layers |
What are Halstad's 7 surgical principles? | strict asepsis, good hemostasis, avoid dead space, minimize tissue trauma, maintain blood supply, avoid tension, adapt corresponding tissue layers |
