Direct Restoration of Endodontically Treated Teeth Flashcards
Name 7 steps of the pre-operative assessment
- Endodontic status
- Anatomical factors
- Tooth position in the mouth
- Periodontal status
- Restorability of the tooth
- Occlusal factors
- Aesthetic concerns
Describe the endodontic status during a pre-operative assessment
- Any previous root filling / quality?
- Presence of pathology?
Describe the anatomical factor during a pre-operative assessment
- Number, shape and position of roots
- Number of canals
- Curvature
- Patency
Describe the tooth position in the mouth during a pre-operative assessment
- Anterior or posterior
- Angulation
- Over eruption
Describe the periodontal status during a pre-operative assessment
- Pocketing
- Localised deep narrow pocketing consider root fracture
- Mobility
- Perio-endo lesions
Describe the restorability of the teeth during a pre-operative assessment
- Amount of the remaining tooth structure
- Condition of the existing restoration
Describe the occlusal factors during a pre-operative assessment
- Occlusal contacts in ICP, RCP and lateral excursions
- Vulnerable cusps
Describe the aesthetic concerns during a pre-operative assessment
- Involved in the aesthetic zone
- Discolouration
Name 3 effects of endodontic treatment on the integrity of the tooth
- Weakening of tooth structure
- Changes to structure and property of dentine
- Changes to mechanoreception of PDL
Name 4 ways the tooth is weakened by endodontic treatment
- Carious lesion
- Access cavity
- Changes to properties of dentine
- Force of cold lateral condensation
Name 4 ways structure and property of dentine is changed by endodontic treatment
- Collagen depletion
- Sodium hypochlorite / EDTA
- Medicaments
- Possible heat generated
Name 3 ways structure and property of mechanoreceptors of PDL is changed by endodontic treatment
- Loss of neurosensory feedback with biting forces
- Higher pain threshold in non-vital teeth
- Increased loading of non-vital teeth
Describe the 5 essential components of a restoration following endodontically treated teeth
- Coronal seal
- Restore function
- Improve the aesthetics
- Maintain gingival health
- Cuspal coverage
Describe the essential component of a restoration following endodontically treated teeth - “Coronal Seal”
- Critical to prevent reinfection
- Should be carried out as soon as possible
- Applied either directly or indirectly
- Isolation achieved by rubber dam, cotton wool and well-adapted matrix
Describe the essential component of a restoration following endodontically treated teeth - “Restore Function”
- Restore tooth back into articulation
- Provide occlusal centric stops
- Approximal contact points
- Prevents tilting and over eruption
