Study Notes
Conservative Management of Residual Caries
- Complete caries removal is necessary to eliminate all bacterial traces of carious dentin.
- If pulp exposure occurs, endodontic treatment is required.
- Partial caries removal differentiates between affected and infected dentin (using a caries detector dye).
- Chemo-mechanical caries removal (e.g., Carisolv, ozone, enzymes, laser cutting) is employed.
- Indirect pulp capping is used if pulp is exposed.
- Direct pulp capping can be used as well and depends on indication.
Caries Removal Techniques
- Avoid burs with sharp edges for pulpal and axial walls.
- Employ low-speed round burs for caries removal.
- Do not leave undermined enamel occlusally.
- Do not flatten pulpal or axial walls of a tooth during caries removal.
- Remove only the infected carious material, preserving the rounded or concave shape of the remaining wall that surrounds the caries removal depression.
- Remove residual caries from the DEJ (dentinoenamel junction) or enamel wall.
Differentiation Between Acute and Chronic Caries
- Acute caries involves multiple teeth and shows a lighter color.
- Chronic caries is slow-developing and displays a dark brown or leathery appearance.
- Caseous consistency is a feature of acute caries, making excavation challenging.
- Sensitivity is often higher in acute caries.
Arresting Caries
- Arrested caries presents stationary or static conditions without progression.
- Sclerotic dentin, a hard, dark discoloration of the tooth, is a sign of arrested caries.
- Sclerosis of the dentinal tubules and secondary dentin formations are commonly associated with arrested caries.
Sclerotic Dentin
- The dentin hardens, becomes denser, less sensitive and more protective toward the pulp.
- Mineralization occurs around the peritubular dentin.
- The ends of Tomes fibers transform into a calcified barrier or calcific barrier.
Direct Pulp Capping
- Successful direct pulp capping is more likely when the tooth is asymptomatic before the procedure, the exposure is 0.5 mm or less, there is reduced hemorrhage, the procedure is atraumatic and the tooth is not desiccated.
Caries Control Techniques
- Extensive active caries in many teeth can be addressed in one visit through removal of infected dentin and temporary restorations for each tooth.
Removing Undermined Enamel and Caries
- Demineralized enamel appears opaque and chalky, whereas carious dentin appears soft, mushy, gummy, leathery, or sticky.
- Removing undermined enamel and carious dentin at the Dentin-Enamel Junction (DEJ) is crucial.
Pulp Capping Materials
- Calcium hydroxide is capable of stimulating tertiary dentin formation, but it's susceptible to moisture and resorbs over time.
- Mineral trioxide aggregate (MTA) material has biocompatibility and induces calcium phosphate formation at the interface of the pulp and periodontium.
- Biodentine, a calcium silicate-based material, creates homogeneous dentin and is bioactive, with an easy handling profile and short setting time.
Pulp Capping Criteria
- Vital pulp preservation and absence of symptoms are ideal criteria for successful pulp capping.
- Absence of periapical changes on radiographic examination, with radiographic evidence of reparative dentin formation.
- Periodic follow-ups are necessary to monitor the patient's condition.
Liners and Bases
- Liners and bases depend on dentin thickness, restorative type (metallic or non-metallic) and adhesive properties.
- They're applied at the pulpal floor close to the pulp for maximum effectiveness.
