Endodontic Treatment (Vital/ Non-Infected Teeth)
Dr. Soucie received his master’s thesis for his study of bacterial penetration of tooth structure. For vital (Alive/ intact pulp tissue) teeth a single-visit approach is warranted. In necrotic teeth, a single-visit approach only serves to entrap bacteria in the tooth, and therefore requires additional steps
Necrotic (Non-vital/ dead) teeth no longer possess viable pulp tissue and are infected. Bacteria has penetrated into the dentinal tubules. Interim medicament must be placed and left inside of the tooth for several weeks to eliminate bacteria from the dentin.
Left: Lateral, furcal and apical bone loss (11mm W x 13mm T x 8mm D) associated with bacterial infection and deemed non-restorable due to suspected fracture and poor periodontal prognosis
Right: Minimally invasive access to preserve tooth structure (Truss/ H-shaped access) with bone remineralization/ healing following microbiological protocol
Retreatment of failed root canals is do to residual bacteria, missed canals and incomplete removal of necrotic tissue in the tooth. Dr. Soucie will not complete treatment of tooth that is infected. Medicine is placed inside the tooth to eliminate the bacterial presence and allow bone healing prior to completion of the root canal.
Left: Missed canals retain resulted in periapical and lateral bone loss(18mm W x 22mm x 8mm D), spreading into the adjacent soft tissue
Right: Complete resolution of the lesion following microbiological protocol without need for apical surgery
CT scans reveal accurate bone loss, fracture and internal anatomy. Non-restorable teeth are surgically extracted, bone graft and membranes are placed to facilitate eventual implant placement when desired. A follow up CT is taken 4 months later to ensure proper healing for implant placement. CT scans are sent to the appropriate party for implant placement and restorative therapy.
Replacement of displaced and avulsed (Knocked out) teeth and splinting of loose teeth. Root canal therapy and any required adjunctive therapy, such as the placement of posts and cores are performed. Crowns, when indicated, are performed by you general dentist or prosthodontist.

Root resorption therapy is a viable treatment to eliminate the pathological process that results in the progressive loss of dentin and cementum by the action of osteoclasts. If left unnoticed or untreated, the resorptive lesion progresses and the affected teeth become non-salvagable and must be extracted
