Use this deck as a recall session

Operative dentistry is easier to revise when you connect each decision to the next one: assess the lesion, protect the pulp, isolate the tooth, restore its shape and check the result. Flashcards can help you retrieve the principles quickly, but they work best when you explain why the answer matters rather than memorising a phrase alone.

This 18-card deck covers foundational concepts that commonly apply across operative dentistry. Materials and clinical protocols vary, so check the instructions for use for the specific adhesive or restorative material you are studying, and use your course’s guidance where recommendations differ. In MySummaries, a deck can be made from a revision board built from your own course notes. Here is a deck to work through now.

A deck on these core operative dentistry decisions looks like this:

Cards — Operative Dentistry — Core Principles18 due

In a deep carious lesion in a vital tooth, what dentine may be left at the pulpal wall during selective caries removal?

Soft or leathery dentine may be left close to the pulp to reduce the risk of exposure; remove caries to firm or hard dentine at the peripheral seal zones.

All 18 cards
In a deep carious lesion in a vital tooth, what dentine may be left at the pulpal wall during selective caries removal?Soft or leathery dentine may be left close to the pulp to reduce the risk of exposure; remove caries to firm or hard dentine at the peripheral seal zones.
Why should peripheral cavity margins be cleaned to sound, hard tooth tissue?To support a durable seal. Soft carious tissue at the restoration margin can compromise the interface and increase the chance of marginal breakdown.
What is the main purpose of rubber dam isolation during an adhesive restoration?Moisture and contamination control, as well as protection of the patient from aspiration or ingestion of small instruments and materials.
What does the C-factor describe in a cavity restoration?The ratio of bonded to unbonded surfaces. A higher ratio can constrain composite shrinkage during polymerisation and increase stress at the bonded interface.
For conventional light-cured resin composite, what is a commonly used maximum increment thickness, subject to the product instructions?About 2 mm per increment for many conventional composites; follow the material’s instructions, including for shade, opacity and curing light.
What is the function of phosphoric-acid etching on enamel in an etch-and-rinse adhesive technique?It creates microporosities in enamel that allow resin infiltration and micromechanical retention after rinsing and drying as directed.
In an etch-and-rinse technique, why should etched dentine not be desiccated?Over-drying can collapse the exposed collagen network, limiting resin infiltration. Follow the adhesive’s specified dentine-moisture protocol.
What is the oxygen-inhibited layer on a resin composite?A superficial resin layer whose polymerisation is inhibited by oxygen. It can assist bonding between increments, but the final surface should be finished and polished as appropriate.
What is the main role of a wedge with a matrix band for a Class II restoration?Adapt the matrix at the gingival margin and help separate the teeth slightly to compensate for band thickness and establish a proximal contact.
What is one advantage of a sectional matrix system for a posterior composite?It can help produce a natural proximal contour and contact, often used with a separation ring; correct placement and adaptation remain essential.
What is the setting reaction of conventional glass ionomer cement?An acid–base reaction between the aqueous polyacid and fluoroaluminosilicate glass, producing a cement matrix.
How does glass ionomer cement attach to tooth structure?By ionic interaction with mineralised tooth tissue, alongside micromechanical contributions; surface conditioning may be recommended by the manufacturer.
What distinguishes resin-modified glass ionomer cement from conventional glass ionomer cement?It has an additional resin polymerisation reaction as well as the acid–base reaction; handling and curing instructions are product-specific.
What is a limitation of calcium hydroxide as a direct pulp-capping material?It has relatively low mechanical strength and can dissolve over time, so material choice and case selection should follow current clinical guidance.
Which material group is commonly used for vital pulp therapy because of its bioactivity and sealing properties?Hydraulic calcium silicate cements, such as mineral trioxide aggregate or other calcium silicate products; follow the product instructions and clinical guidance.
Why should a newly placed restoration be checked in occlusion?To identify and adjust premature or excessive contacts that could cause discomfort or place avoidable load on the restoration.
What should finishing and polishing aim to achieve at a composite restoration margin?A smooth, well-adapted margin without overhangs or roughness, while preserving tooth anatomy and avoiding damage to adjacent tissue.
What should you do if saliva or blood contaminates an adhesive surface during bonding?Follow the adhesive manufacturer’s contamination and reconditioning protocol. Do not assume that simply adding more adhesive will restore the bond.

Work through each card, not just the answer

For each prompt, pause and retrieve the answer before reading it. Then say the answer in a complete sentence and add one clinical consequence. For example, for selective caries removal, explain both what may remain near the pulp and why the peripheral seal zone matters. That second step reveals whether you understand the decision or have only memorised a phrase.

After revealing the answer, grade your recall honestly: easy if you retrieved it promptly and accurately, harder if you needed effort, and difficult if you missed a key part. If you remembered “leave dentine” but forgot that the peripheral margin should be hard, treat that as an incomplete answer. Review difficult cards sooner than easy ones; repeated, spaced retrieval is more useful than repeatedly rereading the whole deck in one sitting.

Some cards describe a general principle, not a universal instruction for every product or patient. The composite increment card is a good example: about 2 mm is a common limit for conventional light-cured composite, but the product instructions govern. The same applies to adhesive moisture management, glass ionomer conditioning and curing. In an assessment, state the principle, then qualify a material-specific step where appropriate.

The core checklist behind the deck

Use this short checklist after the cards. It brings the facts together in the order you might use them when planning or explaining a restoration. If you cannot explain one item without looking, return to the linked card rather than rereading everything.

The board’s “Must not miss core” for this deck is:

Must not miss coreOperative Dentistry — Core Principles
Deep caries in a vital tooth: selective removal may leave soft or leathery dentine near the pulp; clean peripheral margins to firm or hard dentine for a seal.
Adhesive success depends on isolation and correct, product-specific surface treatment; follow the manufacturer’s contamination and moisture protocol.
Conventional light-cured composite is commonly placed in increments of about 2 mm, subject to the material’s instructions and curing requirements.
For a Class II restoration, adapt the matrix at the gingival margin and use the wedge to assist adaptation and compensate for band thickness.
Check proximal contour, marginal adaptation, finishing and occlusion; do not treat placement as complete until the restoration has been assessed.
The five high-value principles that the operative dentistry deck is designed to reinforce.

Turn missed facts into a targeted review

When a card is wrong, identify the exact missing point. Was it a threshold, a material reaction, a reason for a technique or a safety step? Write a short prompt that tests that point rather than copying the whole answer. Then retest it after a gap and again in a later session. For a complex concept such as deep caries management, make separate prompts for the pulpal wall and the peripheral seal; one overloaded card can hide which part you do not know.

If you miss the selective-removal card twice, a useful remediation prompt is:

A practical routine for the next study session

Use the deck in a short cycle. First, answer all 18 cards without notes. Second, sort the misses into knowledge gaps and wording gaps. A knowledge gap means the principle itself is unclear; return to your notes or teaching material before trying again. A wording gap means you knew the idea but omitted a useful qualifier, such as “follow the manufacturer’s instructions”. Third, answer only the difficult cards again, explaining the clinical reason aloud. Finish by applying two or three principles to a case from your own course material.

For example, given a deep carious lesion in a vital posterior tooth, describe how you would balance caries removal with pulpal risk, what you need from the peripheral seal, how you would isolate and restore the tooth, and which checks you would make before finishing. Keep the answer tied to the details provided in the case; do not assume that every lesion, material or pulp diagnosis calls for the same approach.

Build your next deck from local teaching notes, especially where your course specifies a particular adhesive system, pulp-therapy pathway or restorative material. Keep stable principles in one deck and product-specific steps in another. This makes review more precise and reduces the risk of applying a general flashcard answer as though it were a universal protocol.
