The Local Effect of Vitamin K2 on Bone Remodeling in Socket Preservation

This study is a randomized controlled trial comparing the effects of socket grafting with crushed vitamin K2 (menaquinone)capsules versus no grafting on bone density and socket dimensions following tooth extraction. Patients are randomly assigned to one of two groups:

Study Group (Group I): Patients receive socket grafting with crushed vitamin K2 (menaquinone) capsules. The socket is covered with an absorbent sponge, and non-resorbable sutures are placed to stabilize the graft material and achieve soft tissue stability.

Control Group (Group II): Patients undergo socket healing without grafting. The socket is covered with an absorbent sponge, and non-resorbable sutures are placed over it.

Outcome measures include bone socket dimensions evaluated immediately after extraction with graft material, as well as assessment after 4 months using cone beam computed tomography (CBCT) radiographs. Additionally, core biopsies are taken at the time of implant placement.

About this study

The study is designed as a randomized controlled trial to investigate the effects of socket grafting with crushed vitamin K2 (menaquinone) capsules compared to no grafting on bone density and socket dimensions following tooth extraction.

Participants: Patients scheduled for tooth extraction are enrolled in the study and randomized into two equal groups.

  • Interventions
  • Patients were randomly divided into two equal groups.

In both groups:

Tooth extraction will perform under local anesthesia All sockets were thoroughly curetted to remove granulation tissue, followed by irrigation and rinsing with sterile saline.

Bone density and socket dimensions will be evaluated immediately after extraction with graft material and after 4 months by using a cone beam computed tomography (CBCT) radiograph and at the time of implant placement core biopsy will be taken.

In group I (study): the socket will be filled with crushed capsule of vitamin k211. Interventions

In group I (study): the socket will be filled with crushed capsule of vitamin k2 and cover with an absorbent sponge a Figure of eight tension-free non-resorbable 3-0 sutures will be placed over the filled socket to stabilize the graft material in the socket and to achieve soft tissue stability.

in group II (control): the socket will be left to heal without grafting, and it will be covered with an absorbent sponge. A figure-of-eight tension-free non-resorbable 3-0 sutures will be placed over the socket.

the socket will be filled with crushed capsule of vitamin k2 menaquinone in study group

Other names: vitamin k2 (Menaquinone)

Primary outcomes

  1. Marginal bone loss

    Time frame: baseline and 4 month after extraction

    At the time of extraction, CBCT imaging will provide baseline data on the initial bone structure This baseline measurement serves as a reference point for evaluating any subsequent changes in bone density and morphology.

    After four months, another CBCT scan will be conducted to assess the amount of marginal bone loss that has occurred since the initial extraction. By comparing the post-extraction CBCT images with those taken after four months, researchers can quantify any changes in bone volume and identify any areas of concern related to bone resorption. The unit of measurement for the primary outcome, vertical bone change (socket height), is millimeters (mm).

Secondary outcomes

  1. Primary stability

    Time frame: at time of implant placment

    For the primary stability assessment, the Implant Stability Quotient (ISQ) will be utilized. ISQ is a non-invasive and widely used method for evaluating the initial stability of dental implants during placement. Unit of Measurement: Implant Stability Quotient (ISQ)

  2. amount of new bone formation

    Time frame: baseline and 4 month after extraction

    amount of new bone formation," histomorphometric analysis will be employed. This method involves the microscopic examination and quantification of bone tissue characteristics to assess the extent of bone formation.

    Histomorphometric analysis allows researchers to evaluate the quality and quantity of newly formed bone in the extraction site or implantation site. It involves taking tissue samples (biopsies) from the area of interest and then processing these samples for microscopic examination. Unit of Measurement: Bone area percentage (%)

Other outcomes

  1. Secondary stability

    Time frame: 4 month post-implant placement

    the Implant Stability Quotient (ISQ) will be utilized. ISQ is a non-invasive and widely used method for evaluating the stability. Unit of Measurement: Implant Stability Quotient (ISQ)
