About this trial

This is an interventional treatment trial for Cleft Lip and Palate

Eligibility Criteria

7 Years - 12 Years (Child)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • non syndromic unilateral cleft lip and palate;
  • age between 7 and 12 years;
  • to have the jaw aligned and ready to receive the graft.

Exclusion Criteria:

  • previous surgery to correct the alveolar cleft;
  • have the canine erupted before grafting;
  • incomplete orthodontic treatment;
  • incomplete CT scan documentation.

  • Hospital Sírio-Libanes

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

Mesenchymal stem cells associated with biomaterials

Iliac crest autogenous bone graft

Arm Description

Mesenchymal stem cells obtained from autogenous deciduous dental pulp associated with biomaterials. The stem cells will be obtained by enzimatic digestion in GMP laboratory and will be seed into the biomaterial (hydroxyapatite/collagen).

Autogenous bone will be obtained from iliac crest. The prepare of the receptor area will be the same in both arms and will follow current recommendations.

Outcomes

Primary Outcome Measures

Alveolar bone filling rate
Alveolar bone filling rate defined by the filling of at least 70% of the alveolar cleft area.
Serious adverse events
Serious adverse events resulting in death, life-threatening event, hospitalization, prolongation of existing hospitalization (for > 24 hours), persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions. Important medical event that may not result in death, be life threatening, or require hospitalization may be considered a serious adverse drug experience when, based upon medical judgment, it may jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Frequency of participants experiencing at least one serious adverse event.

Secondary Outcome Measures

Non serious adverse events
Frequency of participants experiencing at least one non serious adverse event
Bone Tissue Engineering With Dental Pulp Stem Cells for Alveolar Cleft Repair
Position of the canine tooth and formation of dental root
Position of the canine tooth and formation of dental root assessed by CT scan
Alveolar bone filling rate
Alveolar bone filling rate defined by the filling of at least 70% of the alveolar cleft area.
Serious adverse events
Serious adverse events resulting in death, life-threatening event, hospitalization, prolongation of existing hospitalization (for > 24 hours), persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions. Important medical event that may not result in death, be life threatening, or require hospitalization may be considered a serious adverse drug experience when, based upon medical judgment, it may jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Frequency of participants experiencing at least one serious adverse event.
Patient-reported outcome (PRO, including appearance, fuction and quality of life)
Assessed by CLEFT-Q, a self-report PRO instrument, tool answered independently patients themselves, without interpretation by the parent(s) or healthcare provider. The CLEFT-Q consists of 13 independently functioning domains (171 items) measuring appearance, facial function and quality of life. Each domain is composed of a series of items that together evaluate a unidimensional construct. A higher score means a better result (continuous outcome, measured by: mean)

5. Study Description

Brief Summary
Iliac crest autogenous bone graft is accepted as the most effective method for secondary alveolar cleft repair. However this method is associated with complications. As an alternative, mesenchymal stem cells associated with biomaterials have been used for the rehabilitation of the alveolar bone cleft of patients with cleft lip and palate. This is a RCT comparing mesenchymal stem cells obtained from autogenous deciduous dental pulp associated with biomaterials versus iliac crest autogenous bone graft for secondary alveolar cleft repair.
