About this study

The aim of the study will be achieved through the following primary and secondary objectives. The primary objective is to evaluate the regenerative potential of Straumann Emdogain by comparing the change in clinical attachment level from baseline to 12 months between the test and control arms. The regenerative potential of Straumann Emdogain will also be assessed by comparing the changes in gingival margins, changes in average probing pocket depth, changes in full mouth plaque score, changes in bleeding on probing, and changes in root dentin hypersensitivity from baseline to 12 months between the test and control arms.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subjects must have voluntarily signed the informed consent form before any study related procedures
  • Subjects must be males or females who are 18-85 years of age
  • Subjects must have moderate to severe chronic, generalized periodontitis with pockets of 5 mm - 8mm probing depth in at least 2 pockets per contralateral quadrants in one arch (study teeth)
  • Subjects must be committed to the study and the required follow-up visits
  • Subjects must be in good general health as assessed by the Investigator

Exclusion criteria

  • Subjects taking or intending to take any medications during the duration of the study that will potentially affect healing and inflammation
  • Subjects who are currently heavy smokers (defined >10 cigarettes per day or >1 cigar per day) or who use chewing tobacco
  • Subjects being treated with systemic antibiotics or subjects that were treated with systemic antibiotics within 3 months prior to treatment in this study
  • Subjects with uncontrolled diabetes
  • Subjects that are immunocompromised or immunosuppressed
  • Subjects that cannot provide informed consent
  • Subjects with drug or alcohol abuse
  • Subjects that have undergone periodontal root planing or periodontal surgery in the last 6 months
  • Subjects that are pregnant
  • Subjects with necrotizing periodontitis or periodontitis related to systemic disease
  • Teeth with pockets with probing depth ≥ 9 mm will not classify as study teeth
  • Teeth with pockets or defects with furcation involvement will not classify as study teeth
  • Teeth with mobility degree > 1 without splint will not classify as study teeth
  • Subjects with test and control sites in the two quadrants on adjacent teeth
  • Patients with compromised health conditions such as diabetes, systemic diseases, high dose steroid therapy, bone metabolic diseases, radiation or immune-oppressive therapy, and infections or vascular impairment at the surgical site
  • Subjects with conditions or circumstances, in the opinion of the Investigator , which would prevent completion of study participation or interfere with analysis of study results

Treatment and study plan

Scaling and Root Planing

Procedure

Using minimally invasive surgical procedure (scaling and root planing) with Emdogain application to treat one contra-lateral quadrant in subject's jaw.

Scaling and root planing without Emdogain

Procedure

Using minimally invasive surgical procedure (scaling and root planing) without Emdogain application to treat one contra-lateral quadrant in subject's jaw.

Emdogain application

Device

Using minimally invasive surgical procedure (scaling and root planing) with Emdogain application to treat one contra-lateral quadrant in subject's jaw

Primary outcomes

  1. Change in Clinical Attachment Levels (CAL)

    Time frame: Baseline and 12 Month Follow-Up Visit

    CAL will be measured in millimeters on the study teeth at 6 locations. Outcome is mean change of CAL from baseline measurements at surgery to 12-months post-surgery, taken from the deepest pocket of a patient's test and control teeth measured at baseline. Analysis will compare the mean change of CAL for test and control treatment arms.

Secondary outcomes

  1. Change in Gingival Margin (GM)

    Time frame: Baseline and 12 Month Follow-Up Visit

    GM will be measured in millimeters on the study teeth at 6 locations. Outcome is mean change of GM from baseline at surgery to 12-months-post surgery, taken from the deepest pocket of a patient's test and control teeth measured at baseline. Analysis will compare the mean change of GM for test and control treatment arms.

  2. Change in Pocket Probing Depth (PPD)

    Time frame: Baseline and 12 Month Follow-Up Visit

    PPD will be measured in millimeters on the study teeth in 6 locations. Outcome is mean change of PPD from baseline at surgery to 12-months post-surgery, taken from the deepest pocket of a patient's test and control teeth at baseline. Analysis will compare the mean change of PPD for test and control treatment arms.

  3. Change in Full Mouth Plaque Score (FMPS)

    Time frame: Baseline and 12 Month Follow-Up Visit

    FMPS will be calculated based on the number of tooth surfaces with plaque over the total number of tooth surfaces x 100. The value is presented as a percent. The difference in FMPS between 12 months and baseline will be determined.

  4. Change in Bleeding on Probing (BoP)

    Time frame: Baseline and 12 Month Follow-Up Visit

    For the categorical variable BoP, the frequency of bleeding (present or absent) will be counted (absolute and in percent) over all measured sites around the identified study teeth for each treatment group. The results will be compared between the 12-month follow-up and baseline.

  5. Change in Root Dentin Hypersensitivity

    Time frame: Baseline and 12 Month Follow-Up Visit

    Presence of root dentin hypersensitivity will be recorded as "none" (no reaction from the subject), "mild" (sensible with no pain), "moderate" (sensible with slight pain), or "severe" (sensible with pain that persists for a while) after a conventional air blast is applied to the study tooth. Changes in the frequency of categories will be determined and compared between the two treatment arms. An improvement is defined as a decreased reaction (for example, severe to mild), a deterioration is defined as increased reaction (for example, none to moderate), and unchanged is no change to reaction (for example, mild to mild).

  6. Change in Post-surgical Pain

    Time frame: 1-2 days post surgery, 1 week post surgery, and 2 weeks post surgery

    Post-surgical pain will be measured on a 100 millimeter visual analog scale. The range is 0 (no pain) to 99 (nearly maximum pain). The lower the value, the better the outcome. The subjects will be instructed to mark their level of pain on a line for both the test quadrant and the control quadrant. The average change in pain level will be determined and compared between the two arms.
