Clinical Trial 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

Type	Measure	Description	Time frame	Safety issue
Primary	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.	12 weeks
Primary	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.	12 weeks
Secondary	Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]	Proximal second molars continue to erupt normally; Proximal second molars have no radiographic evidence of crown alteration; Surgical site is completely healed over on visual exam; Radiographic assessment of the surgical site is WNL expected or post op healing; No adverse events related to the 3TBA procedure; No reported neurological changes to tongue or lip	12 weeks
