Study Notes
Introduction to Operative Dentistry
- Operative dentistry is the art and science of dentistry dealing with diagnosis, treatment, and prognosis of tooth defects.
- These defects do not necessitate full coverage restorations.
To Restore
- Restorations aim to recover form, function, and esthetics of teeth.
Indications of Operative Dentistry
- Caries: Cavities resulting from bacterial action.
- Loss of tooth structure: Due to attrition, abrasion, abfraction, erosion (non-carious lesions).
- Malformed, traumatized, or fractured teeth: Including those that have been impacted or broken.
- Aesthetic improvement: Improving the appearance of teeth, e.g., discoloration.
Dental Caries
- Dental caries is a multifactorial infectious microbiological disease that results in localized dissolution and destruction of calcified tissue.
- Factors affecting caries include host (teeth), microorganisms, and substrate (e.g. CHx (bacteria)).
- Caries types involve: pit and fissure, smooth surface, root cavities.
Attrition
- Attrition is mechanical wear between opposing teeth due to normal or para-functional movements such as bruxism.
Abrasion
- Abrasion is abnormal tooth surface loss due to direct frictional forces between teeth and external objects.
Erosion
- Erosion is loss of hard dental tissue resulting from chemical processes not involving bacteria.
- Exogenous sources include lemon-sucking, and battery factors.
- Endogenous ones include gastric fluid regurgitation (Gastro-esophageal reflux).
Abfraction
- Abfraction is an angular notch at the gumline caused by bending forces applied to the teeth.
- Factors include chronic heavy forces (bruxism), or normal forces on teeth with improper alignment (malocclusion).
Malformed, Traumatized or Fractured Teeth
- These are damaged or malformed teeth that need restoration.
Teeth Discoloration
- Teeth discoloration is a visible issue that can be improved by various dental procedures.
Enamel Hypoplasia
- Enamel hypoplasia is a defect in tooth enamel, causing thin and deficient enamel due to defects in the enamel matrix formation.
- It usually creates a pitting in the tooth.
- Enamel hypoplasia severity can range from moderate to severe.
Enamel Hypo-calcification
- Enamel hypo-calcification is a tooth enamel defect where a normal amount of enamel is produced, but the enamel is softer than usual due to a lack of sufficient mineralization.
Aesthetic Improvement
- Aesthetic improvement procedures correct the aesthetic issues of teeth.
Restoration or Repair
- Restoration or repair involves replacing or fixing damaged teeth.
Scope of Operative Dentistry
- Diagnosis: Identifying the dental problem.
- Prevention: Implementing strategies to avoid future issues.
- Interception: Detecting and acting on early problems.
- Preservation: Maintaining healthy teeth.
- Restoration: Returning damaged teeth to a functional state.
- Maintenance: Ongoing care after treatment.
Objective of Operative Dentistry
- Restore tooth function to normal.
- Return teeth to normal occlusion.
- Improve overall oral health and hygiene.
- Motivate patients for routine checkups.
- Provide post-operative instructions.
