About this study
Official title: Evaluation of Injectable Beta- Tricalcium Phosphate as an Occlusive Barrier Membrane in Treatment of Grade ii Furcation Involvement (Clinical and Radiographic Study)
This study will be conducted to evaluate clinically and radiographically the use of PD VitalOs cement® bone graft in the treatment of class II furcation defects comparing with Hydroxyapatite bone graft and biodegradable collagen membrane in the treatment of class II furcation defects.

Group II (Control group): included seven Grade II furcation defects treated with granulated beta tricalcium phosphate bone graft covered by resorbable collagen membrane.

| Study group | Role | What they receive |
|---|---|---|
| PD VitalOs cement® alone | Experimental | class II furcation defects that will be treated with PD VitalOs cement® alone Receives: Other: PD VitalOs cement® |
| PD VitalOs cement® plus Bone graft and membrane | Experimental | PD VitalOs cement® and Hydroxyapatite bone graft and biodegradable collagen membrane in the treatment of class II furcation defects. Receives: Other: PD VitalOs cement®; Other: Hydroxyapatite bone graft; Other: biodegardable collagen membrane |
What is being measured
The primary outcome is the main question the study is designed to answer.
change in plaque index scores (PI) according to Silness and Löe.
Score 0 = no plaque in gingival area. Score 1= film of plaque adhering to the free gingival margin and the adjacent area of the tooth, plaque may only be recognized by running a probe across the tooth surface.
Score 2= moderate accumulation of soft deposits within the gingival pocket and on the gingival margin and/ or adjacent tooth surface which can be seen by the naked eye.
Score 3= abundant of soft matter within gingival pocket and/ or the gingival margin and adjacent tooth surface.
The scores from the four surfaces of the tooth were added and divided by (four) to give plaque index for each tooth; the plaque index score for an individual was obtained by adding the indices of the teeth and dividing by the number of the teeth examined.
Measured: at 3 weeks and 6 weeks
change in probing Pocket Depth(PPD)
The measurements were carried out to the defects selected using an 0.8 mm thick periodontal probe * with William's calibration, which was marked from (1-10) mm, pocket depth of (1 mm) or less was recorded as (1mm),measurements exceeding (1mm) but less than (2mm) were recorded as (2mm) so that the probing pocket depth was measured to the nearest mm.
Probing pocket depth refers to the distance from the gingival margin to the bottom of the pocket. Mesial and distal pockets were measured as well as the furcation from the buccal aspect as close as possible to the contact points, facial and lingual pockets were measured at midline of roots.
Efforts were made to insert the probe parallel to the long axis of the roots. Light force was used during the introduction of the probe to the bottom of the pocket, third molars and teeth with enamel projections were excluded. (7)
Measured: at 3 weeks and 6 weeks
change in clinical Attachment Level

Questions about this trial
What is this clinical trial studying?
A study testing PD VitalOs cement®, Hydroxyapatite bone graft and biodegardable collagen membrane in people with Furcation Defects, run by Hams Hamed Abdelrahman at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
change in plaque index scores (PI) according to Silness and Löe. (time frame: at 3 weeks and 6 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04443972, which also lists 28 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jun 2020; AzTrials last refreshed its copy on 7 Nov 2026.
