Conditions

Cleft Lip and Palate

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.

Interventions

Deciduous dental pulp mesenchymal stem cells associated with hydroxyapatita/collagen.

COMBINATION_PRODUCTIliac crest autogenous bone graft

Autogenous bone will be obtained from iliac crest.

Design outcomes

Primary

MeasureTime frameDescription
Alveolar bone filling rate12 monthsAlveolar bone filling rate defined by the filling of at least 70% of the alveolar cleft area.
Serious adverse events12 monthsSerious 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

MeasureTime frameDescription
Position of the canine tooth and formation of dental root12 monthsPosition of the canine tooth and formation of dental root assessed by CT scan
Alveolar bone filling rate6 monthsAlveolar bone filling rate defined by the filling of at least 70% of the alveolar cleft area.
Non serious adverse events15 days; 3, 6 and 12 monthsFrequency of participants experiencing at least one non serious adverse event
Patient-reported outcome (PRO, including appearance, fuction and quality of life)pre surgery and 12 monthsAssessed 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)
Serious adverse events15 days; 3 and 6 monthsSerious 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.
