General Dentistry Flashcards Chapter 48

Restorative Dentistry

• Restorative dentistry is also known as operative dentistry, focusing on restoring teeth that are decayed or damaged.

Decay Terminology

• Decay is commonly referred to as a cavity, indicating the deterioration of tooth structure.

Cavity Preparation

• The procedure for removing decay is called cavity preparation, which is critical for restoring the tooth's function and health.

Cavity Preparation Details

• The pulpal floor is the wall of the cavity preparation that remains perpendicular to the long axis of the tooth, providing stability to the restoration.

Class I Restoration Location

• Class I restorations are found on the occlusal surface, buccal pit of posterior teeth, and lingual pit of anterior teeth, addressing decay in these areas.

Class II Restoration Surfaces

• Class II restorations can affect either two or three surfaces of a tooth, generally involving interproximal areas between teeth.

Class II Restoration Example

• Tooth 13 is an example of a tooth that could be treated with a Class II restoration.

Class IV Restoration Material

• Composite resin is the restorative material typically used for Class IV procedures, often addressing cosmetic concerns and anterior teeth.

Moisture Control Techniques

• Use of a dental dam is recommended for moisture control during Class III and Class IV procedures to maintain a dry working area.

Class V Lesions Population

• Older adults have a higher incidence of Class V lesions, often due to the aging process and associated dental wear.

Intermediate Restoration Purpose

• Intermediate restorations may be placed for various reasons including the health of the tooth, awaiting a permanent restoration, or financial constraints.

Veneer Placement

• Veneers are applied to the facial surface of the teeth, enhancing aesthetics and masking imperfections.

Types of Veneers

• Common types of veneers include direct composite resins and indirect porcelain, providing options for different patient needs and preferences.

Tooth Whitening Indications

• Indications for tooth whitening include extrinsic stains (surface stains), aged teeth, and intrinsic stains (internal discoloration).

Tooth Whitening Application

• A thermoplastic tray is utilized to hold teeth whitening gel in place, ensuring even application across the tooth surfaces.

Tooth Whitening Ingredient

• Hydrogen peroxide is a key ingredient found in tooth whitening strips, acting as a bleaching agent to remove stains.

Adverse Effects of Tooth Whitening

• Patients may experience hypersensitivity during tooth whitening treatments, a common side effect due to the bleaching process.

Classification of MOD Restoration

• An MOD (Mesio-Occluso-Distal) restoration on tooth 14 is classified as Class II, indicating it affects the mesial, occlusal, and distal surfaces.

Classification of Lingual Pit Restoration

• A lingual pit on tooth 8 is classified as Class I, representing a restoration that addresses a single surface on an anterior tooth.

Matrix System Usage

• Class II and III restorations require the implementation of a matrix system to properly mold the restorative material into the cavity.
