Cariology Flashcards
● Caries Classification D1
clinically detectable enamel lesion with intact surfaces
● Caries Classification D2
can be recognized as a cavity but can be remineralized
● Caries Classification D3
clinically detectable lesions in dentin
■ 50% can be non-cavitated, 50% cavitated
■ Might not have to restore
● Caries Classification D4
lesions into pulp
○ About___% of children get S. mutans from____
70
mom
○ Distribution of caries by surface
■ 55% occlusal
● Pit and fissure caries predominate
■ 34% buccal/ lingual
■ 11% smooth surface (interproximally)
○ Current fluoridation levels in water are
1ppm
Guiding Principles for Caries Management
● Five Guiding Principles
○ Assess caries risk status
○ Diagnose the disease early
○ Treat the disease by
■ Remineralizing tooth surface
■ Controlling the infection
○ Avoid or delay operative intervention
○ Restore “active” disease only○ Inadequate saliva flow
less that 0.5 mL/ min
● Normal Pulp
○ A clinical diagnostic category in which the pulp in symptom-free and normally responsive to pulp testing
● Reversible Pulpitis
○ A clinical diagnosis based upon subjective and objective findings indicating that the inflammation should resolve and the pulp return to normal
● Symptomatic Irreversible Pulpitis
○ A clinical diagnosis based on subjective and objective findings indicating that the vital inflamed pulp is incapable of healing
○ Lingering thermal pain, spontaneous pain, referred pain
● Asymptomatic Irreversible Pulpitis
○ A clinical diagnosis based on the subjective and objective findings indicating that vital inflamed pulp is incapable of healing
○ No clinical symptoms but inflammation produced by caries, caries excavation, trauma, etc.
● Pulp Necrosis
○ A clinical diagnostic category indicating death of the dental pulp
○ Pulp is nonresponsive to pulp testing
● Previously Treated
○ Clinical diagnostic category indicating that the tooth has been endodontically treated and the canals are obturated with various filling materials other than intracanal medicaments
● Previously Initiated Therapy
○ Clinical diagnostic category indicating that the tooth has been previously treated by partial endodontic therapy
○ Pulpotomy, pulpectomy, etc.
● Normal Apical Tissues
○ Teeth with normal periradicular tissues that are not sensitive to percussion or palpation testing
○ The lamina dura surrounding the root is intact and the periodontal ligament space is uniform
● Symptomatic Apical Periodontitis
○ Inflammation of apical periodontium producing clinical symptoms including:
■ Painful response to biting, percussion, or palpation
○ May or may not be associated with apical radiolucent area
● Asymptomatic Apical Periodontitis
○ Inflammation and destruction of apical periodontium that is of pulpal origin, appears as an apical radiotranslucent area, and does not produce clinical symptoms
● Acute Apical Abscess
○ Inflammatory reaction to pulpal infection and necrosis characterized by rapid onset, spontaneous pain, tenderness of tooth to pressure, pus formation, and swelling of associated tissues
● Chronic Apical Abscess
○ Inflammatory reaction to pulpal infection and necrosis characterized by gradual onset, little or no discomfort, and the intermittent discharge of pus through an associated sinus tract
● Condensing Osteitis
○ Diffuse radiopaque lesion representing a localized bony reaction to a low-grade inflammatory stimulus, usually seen at the apex of the tooth
● 3 different terms used for the primordial root:
○ Cervical loop
○ Hertwig’s epithelial root sheath
○ Epithelial diaphragm
