NCT05374993

Brief Summary

This single-arm prospective study will enroll a minimum of 7 and a maximum 10 subjects between the ages of 7 and 13 years of age with radiographic evidence of mandibular 3rd molar tooth bud development without enamel formation. Each subject will undergo a 3TBA procedure for each qualifying mandibular 3rd molar tooth buds. Each subject will receive treatment for qualifying mandibular tooth buds during the same session. Subjects will be followed for a minimum of 12 weeks post treatment.

Outcome Measures

Primary Outcomes (2)

  • Tooth Structure Development Assessment

    Efficacy assessment will be performed based on periapical X-rays from Follow-up Visit 3 (12-week post treatment). Effectiveness Assessment will consist of evaluation of Tooth Structure Development and Bony Crypt In Growth using the following scale. Tooth Structure Development Assessment Scale for 3rd Molar: "0" = No radiographic evidence. "1" = Minimal or trace level of detectable radiographic evidence. "2" = Moderate or intermediate level of detectable radiographic evidence of mineralized tooth structure formation with crown formation to be less than 50% complete. "3" = Advanced level of detectable radiographic evidence of mineralized tooth structure formation with enamel formation estimated to be 50% or more complete. Success is defined as a score of "0" or "1" on Tooth Structure Development scale at Follow-up Visit 3 (12-week post treatment). Each treated tooth bud is evaluated individually.

  • Bony Crypt Growth Assessment

    Efficacy assessment will be performed based on periapical X-rays from Follow-up Visit 3 (12-week post treatment). Effectiveness Assessment will consist of evaluation of Bony Crypt In Growth using the following scales. Tooth Structure Development Assessment Scale for 3rd Molar: "0" = No radiographic evidence. "1" = Minimal or trace level of detectable radiographic evidence of mineralized tooth structure formation. "2" = Moderate or intermediate level of detectable radiographic evidence of mineralized tooth structure formation with crown formation to be less than 50% complete. "3" = Advanced level of detectable radiographic evidence of mineralized tooth structure formation with enamel formation estimated to be 50% or more complete. N/I = Not Interpretable. N/A = Not Applicable. Success is defined as a score of "0" or "1" on Bony Crypt Growth Assessment scales at Follow-up Visit 3 (12-week post treatment). Each treated tooth bud is evaluated individually.

Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Subject is between 7 and 13 years of age
  • Subject has radiographic evidence of at least one mandibular 3rd molar tooth bud

You may not qualify if:

  • Subject use of articaine is contraindicated (known hypersensitive to products containing sulfites).
  • Subject has any condition which, in the opinion of the Investigator, would prevent adequate performance of the procedure or affect the health and/or safety of the subject.-
