Four-handed dentistry

A method where the chairside assistant and dentist work together as a team, using preset instrument transfers and ergonomic positioning to reduce fatigue and improve efficiency during dental procedures.

Related: Instrument transfer, Ergonomic positioning
Instrument transfer

The coordinated exchange of dental instruments between the dentist and assistant, typically using a two-handed or one-handed technique to maintain safety and efficiency while minimizing motion.

Related: Four-handed dentistry, Ergonomic positioning
Ergonomic positioning

The arrangement of the patient, dentist, and assistant to minimize physical strain, typically with the patient supine and the team seated with feet flat and thighs parallel to the floor.

Orthodontic bracket

A small attachment bonded to a tooth surface that holds the archwire, used to apply controlled forces for tooth movement in orthodontic treatment.

Related: Archwire, Elastomeric ligature
Archwire

A wire engaged in orthodontic brackets that transmits force to the teeth, guiding them into proper alignment and occlusion during treatment.

Related: Orthodontic bracket, Elastomeric ligature
Elastomeric ligature

A small rubber ring placed around an orthodontic bracket to secure the archwire, available in various colors and sizes, and replaced at adjustment visits.

Related: Orthodontic bracket, Archwire
Standard precautions

Infection control practices applied to all patients regardless of suspected infection status, including hand hygiene, personal protective equipment, and safe handling of sharps and contaminated items.

Related: Personal protective equipment, Hand hygiene
Personal protective equipment

Barrier items such as gloves, masks, eyewear, and gowns worn by dental personnel to protect against exposure to bloodborne pathogens and other infectious materials.

Related: Standard precautions, Hand hygiene
Hand hygiene

The act of cleaning hands with soap and water or alcohol-based hand rub, performed before and after patient contact and after removing gloves to prevent cross-contamination.

Related: Standard precautions, Personal protective equipment
Sterilization

A process that destroys all microbial life, including bacterial spores, on reusable dental instruments, commonly achieved by steam autoclave, dry heat, or chemical vapor.

Related: Autoclave, Biological monitor
Autoclave

A device that uses pressurized steam under high temperature to sterilize dental instruments, requiring proper packaging, loading, and monitoring to ensure effectiveness.

Related: Sterilization, Biological monitor
Biological monitor

A test using bacterial spores to verify that a sterilization cycle effectively killed microorganisms, typically performed at least weekly and after autoclave repairs.

Related: Sterilization, Autoclave
Amalgam

A dental restorative material made by mixing silver alloy powder with mercury, known for strength and durability but requiring careful handling and waste management.

Related: Composite resin, Curing light
Composite resin

A tooth-colored restorative material composed of resin matrix and filler particles, applied in layers and hardened with a curing light for aesthetic fillings.

Related: Amalgam, Curing light
Curing light

A handheld device that emits blue light to polymerize light-cured dental materials such as composite resin and adhesives, requiring proper wavelength and intensity.

Related: Composite resin, Amalgam
Alginate impression material

A hydrocolloid material mixed with water to form a gel used for taking preliminary dental impressions, known for ease of use but limited dimensional stability.

Related: Impression tray, Stone model
Impression tray

A rigid or flexible device used to hold impression material and carry it to the dental arch, available in various sizes and designs for accurate impressions.

Related: Alginate impression material, Stone model
Stone model

A positive reproduction of dental structures created by pouring dental stone into an impression, used for diagnosis, treatment planning, and fabrication of appliances.

Related: Alginate impression material, Impression tray
Bisecting angle technique

An intraoral radiographic method where the central ray is directed perpendicular to the bisector of the angle formed by the tooth and film, minimizing distortion.

Related: Paralleling technique, Radiographic density
Paralleling technique

An intraoral radiographic method where the film or sensor is placed parallel to the tooth and the central ray is directed perpendicular, reducing distortion and improving accuracy.

Related: Bisecting angle technique, Radiographic density
Radiographic density

The overall darkness or blackness of a dental radiograph, influenced by exposure factors and processing, affecting the visibility of anatomical structures.

Related: Bisecting angle technique, Paralleling technique
Informed consent

The process of obtaining a patient's voluntary agreement to a procedure after explaining its purpose, risks, benefits, and alternatives in understandable terms.

Related: Treatment plan, Patient record
Treatment plan

A written outline of the recommended dental procedures, sequenced and prioritized to address the patient's oral health needs, including alternatives, risks, and expected outcomes.

Related: Informed consent, Patient record
Patient record

A documented account of a patient's dental history, examinations, diagnoses, treatments, and communications, maintained for continuity of care and legal purposes.

Related: Informed consent, Treatment plan
Active listening

A communication technique where the listener fully concentrates, understands, responds, and remembers what the patient says, fostering trust and accurate information exchange.

Related: Teach-back method, Health literacy
Teach-back method

A communication strategy where the patient explains information back in their own words to confirm understanding, often used for home care instructions and medication directions.

Related: Active listening, Health literacy
Health literacy

The degree to which individuals can obtain, process, and understand basic health information to make appropriate health decisions, influencing patient education approaches.
