SamEng:  This report concerns long-term (4 to 5 years) clinical evaluation of
         22 resolved (complete bone closure) mandibular Class 2 furcation defe
         cts follo coronally advanced flap procedures and citric acid root tre
         atment with or without adjunctive implantation of freeze-dried, demin
         eralized allogeneic bone. Sixteen buccal furcation sites in 12 patien
         ts were available for the follow-up evaluation. The furcation involve
         ment was independently evaluated by a panel for three furcation index
          systems. Oral hygiene standards, gingival health, probing depth, cli
         nical attachment level, gingival recession, tooth vitality, and detec
         table caries or root resorption were also recorded. Mean attachment l
         evel at the furcation sites was 5.8 ± 2.9 mm, compared to 4.5 ± 2.2 m
         m and 3.5 ± 1.3 mm over the prominence of the mesial and distal roots
         , respectively. The clinical examination further revealed that 12 out
          of 16 sites exhibited recurrent Class 2 furcation involvement. Of th
         e 16 teeth examined, one had received endodontic treatment, while the
          remaining 15 respondied within the normal range to pulp testing. One
          tooth had developed caries in the furcation region. No teeth demonst
         rated periradicular pathology. The results of this study question the
          long-term stability of furcation bone regeneration following coronal
         ly advanced flap procedures.

SamEng:  This study evaluated site-by-site the relations between subgingival m
         icrobial colonization and gingival tissue reactions. Experimental, de
         ep periodontal defects were established at buccal surfaces of mandibu
         lar and maxillary canine teeth in 5 beagle dogs. The root surfaces we
         re instrumented by a flame-shaped, fine-grained, rotating diamond poi
         nt, or by a sharp curet. Following a 10-day postsurgical healing peri
         od, the dogs were fed a plaque-inducing diet for 70 days. The animals
          were then sacrificed an tissue blocks of the experimental sites incl
         uding teeth and periodontal tissues were secured. The buccal gingiva
         was removed and processed for histomorphometric analysis while the te
         eth were prepared for scanning microscopic avaluation of the extent o
         f subgingival microbial colonization. The results revealed that infla
         mmatory cell density in the junctional epithelum and in the connectiv
         e tissue were positively correlated to subgingival microbial coloniza
         tion (P < 0.01). Furthermore, the degree of significance decreased wi
         th increasing distance from the plaque. The present study demonstrate
         s that a close relation may exist between the extent of subgingival m
         icrobial colonization and inflammatory gingival tissue reactions.

SamEng:  Periodontitis is a multifactorial infectious disease affecting primar
         ily a subset of subjects and a subset of sites. Recent microbiologica
         l data ha acknowledged that before desease progression can occur, a s
         usceptible host and site are required, in addition to the presence of
          pathogenic bacteria. This review discusses factors affecting periodo
         ntal disease progression and focuses in particular on the influence o
         f anatomic and iatrogenic root surface characteristics. Retrospective
          studies clearly suggest a strong association between anatomic aberra
         tions and periodontal attachment loss. Cemental tear seems to have th
         e potential to initiate an aseptic, rapid, site-specific periodontal
         breakdown in a non-infected environment, illustrating the complexity
         of the attachment loss process. Recent experimental findings, further
         more, demonstrate a significant influence of root surface instrumenta
         tion roughness upon subgingival plaque formation and gingival tissue
         reactions, as well as a significant and positive relationship between
          subgingival plaque accumulation and inflammatory cell mobilization.
         These results indicate that subgingivally located irregularities may
         form stagnant sites or ecological niches which favor both retention a
         nd growth of organisms. Such events in addition to the progressive in
         flammatory changes may critically influence the subgingival environme
         nt by turning a stable site into an unstable or active periodontitis
         site. Thus, local anatomic and iatrogenic root surface characteristic
         s may have a more profound effect on gingival health than previously
         assumed, particularly on a site level.

Tittel:  A pilot study comparing ketoprofen and acetaminophen with hydrocodone

SamEng:  The aim of this study was to compare ketoprofen to acetaminophen with
          hydrocodone (A/H) in a postoperative perioodntal pain model. A doubl
         e-blind protocol was used. Thirty minutes prior to each procedure, su
         bjects were given orally either 100 mg ketoprofen or a placebo tablet
         . Four hours later, the subjects too either 50 mg ketoprofen (ketopro
         fen group) or 1000 mg acetaminophen with 10 mg hydrocodone (placebo g
         roup). Subjects reported levels of overall discomfort and pain using
         visual analog scales at eight hourly intervals following the first do
         se of ketoprofen or placebo. Information about adverse side effects w
         as requested from the patients in the form of a checklist. The resuls
         ts revealed only small differences between the two drug regimens with
          respect to levels of pain or overall discomfort. A/H provided signif
         icantly better pain relief at Hours 5 and 6, while overall discomfort
          levels were significantly higher with ketoprofen than placebo at Hou
         rs 3 and 4. Pain levels were low for both groups. It is recommended t
         hat additional analgesics for mild to moderate pain should be tested.
