NCT00757159

Brief Summary

The aim of this investigation is to determine whether a synthetic hydroxyapatite is as effective as an enamel matrix protein for periodontal regeneration in patients who have intra-bony periodontal defects.

Interventions

OstimDEVICE

Ostim® is synthetically manufactured and comprises nanocrystalline hydroxyapatite. The small particle size facilitates resorption. Ostim is an aqueous watery paste and can be used to fill bone defects or to build up bony structures in the region of the jaws. Ostim is osteoconductive, facilitating bone growth. It will act as a scaffolding for the new bone. Ostim is absorbed during the healing process, in the beginning it is osseously interweaved and finally replaced by natural bone.

Also known as: synthetic hydroxyapatite

EmdogainDEVICE

Emdogain® consists of sterile lyophilised Enamel Matrix Derivative with sterile aqueous solution of Propylene Glycol Alginate, 30 mg/ml.

Also known as: enamel matrix protein

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males and females aged between 18 and 70 years.
  • Presence of at least one 1- or 2-wall intrabony periodontal defect.
  • Defect width at least 2 mm.
  • Defect depth at least 4 mm.
  • Defect located at a single rooted tooth or at the approximal site of a multi-rooted tooth if the tooth is not affected by a furcation involvement.
  • Written informed consent.
  • Subject must be judged healthy by the investigator at the time of surgery.
  • Subjects must have had a plaque index \< 0.8 at the end of the initial periodontal therapy.

You may not qualify if:

  • Medical conditions required prolonged use of steroids.
  • Standard blood tests performed by the medical practitioner showing leukocyte dysfunction and deficiencies.
  • History of haemophilia, bleeding disorders, or cumarin therapy.
  • History of neoplastic disease requiring the use of chemotherapy.
  • History of radiation therapy of the head and neck.
  • History of renal failure or chronic renal diseases.
  • Chronic liver diseases.
  • Severe or uncontrolled metabolic bone disorders.
  • Uncontrolled endocrine disorders (including diabetes).
  • Current pregnancy at the time of recruitment.
  • Physical handicaps that would interfere with the ability to perform adequate oral hygiene.
  • Use of any investigational drug or device within the 90 day period prior to surgery on study day 0.
  • Alcoholism or chronical drug abuse.
  • Immuno-compromised patients (including HIV).
  • Smokers (occasional smoking is allowed).
  • +7 more criteria
