Adhesion Flashcards
Occlusion
Any contact between the incising or masticating surfaces of the upper and lower teeth.
Static occlusion
It is defined as contact of teeth when jaws are closed.
Dynamic occlusion
It is defined as tooth contact during mandibular movements.
Malocclusion
Any deviation from a physiologically acceptable contact of opposing dentition is called ?malocclusion?.
Occlusal contact
Any contacting or touching of tooth surfaces is called occlusal contact.
Centric relation
“This is maxilla to mandible relationship in which the condyles are in most retruded position in the glenoid fossa, regardless of any tooth-to-tooth relationship. Here the condyles are in the most superior position they can attain in the glenoid fossa. If a healthy joint is correctly positioned and aligned in centric relation, it can resist maximum loading in function with no sign of tension or tenderness.”
Class I: Neutrocclusion
“Here, the mesiobuccal cusp of maxillary first molar should align with the buccal groove of the mandibular first molar. “
Class II: Distocclusion
“In this, the mesiobuccal cusp of maxillary first molar is located in facial embrasure between the first mandibular molars and second premolars. “
Class III: Mesiocclusion
“In this case, mesiobuccal cusp of maxillary first molar lies in distofacial grooves mandibular first molar.”
Surface Contact/Incisor Relationship
Variations in incisor relationships can be open bite, deep bite or cross-bite
EFFECT OF TOOTH PREPARATION ON DENTAL PULP
Pressure, Heat Production, Vibrations Vibrations are an indication, Speed of Rotation, Nature of Cutting Instrument, Use of Coolants
Materials used for Pulp Capping
- Calcium hydroxide
- Mineral trioxide aggregate (MTA)
- Biodentine
- BioAggregate
Remaining dentin thickness (RDT)
is the dentin present between floor of the tooth preparation and pulp chamber. is the best insulator and protector to pulp. <br></br>Should be at least 2mm thick</br>
