Introduction to Operative Dentistry Flashcards
What is operative dentistry?
The art and science of diagnosis, treatment/restoration, and prognosis of defects of the teeth.
What is the aim of operative dentistry?
To restore proper tooth form, function, and aesthetics. This is for both the teeth and their supporting structures to enhance the gneeral health and welfare of the patient.
What considerations must be taken before operative treatment is undertaken?
Patient’s Medical history
Patient’s Dental history
Infection control
Thorough examination of the entire oral cavity
Diagnosis of the disease or the presenting complaint.
Development of a treatment plan for management of entire case.
Knowledge of restorative materials to be used.
Knowledge of the oral environment
Biological knowledge
Knowledge of both dental anatomy and periodontal tissues
Effect on other dental treatments-coordination.
What are the indications for carrying out operative dentistry?
Plaque control
Pain management/pulp protection
Other management (carious, fractured, malformed and/or discoloured teeth)
Replacement or repair of a previously placed restoration
Why is it important for cavities to be classified?
A knowledge of the terminology of tooth surfaces and anatomy is essential in understanding cavity classifications.
Using correct terminology enables efficient communication within the profession.
What are the methods of classification?
Black’s Classification (Class 1 - 7)
Using the name of the tooth surfaces involved (OCC, MO, DO, MOD, B, L, OL, OB, (LAB))
ADA item number
What is a class 1 cavity?
All pit and fissure cavities
Occlusal surfaces of molars and premolars
Occlusal 2/3rds of facial and lingual surfaces of molars and premolars
Lingual surfaces of incisors
What is a class 2 cavity?
Cavities on the proximal surfaces of premolars and molars (most common form of cavity today, involves mesial and/or distal surfaces, usually caries begin just beneath the contact area where plaque stagnates)
What is a class 3 cavity?
Cavities on the proximal surfaces of anterior teeth not involving the incisal edge.
Usually begins just gingivally to the contact point (like class 2s)
What is a class 4 cavity?
Cavities on proximal surfaces of anterior teeth which involve the incisal edge. (result of trauma usually)
What is a class 5 cavity?
Cavities on the gingival 1/3rd of the facial or lingual surfaces of all teeth
May involve cementum, enamel or dentinal surfaces
Usually occur as a result of poor oral hygiene, dry mouth, or high sugar diet.
What are class 6 cavities?
Cavities on the occlusal cusp tips of posterior teeth or on the incisal edges of anterior teeth.
Occurs as a result of wear or dry mouth. Can be characteristic of a high caries rate.
