Patient Safety

Board takeaway

Make safety a repeatable team process:

1. Identify the patient.
2. Confirm the procedure and site.
3. Update the history.
4. Protect the airway.
5. Communicate the plan.

Learn from near misses as well as injuries. Safe care includes equipment, staffing, discharge, and home instructions throughout the visit.

Before treatment

• Use at least 2 patient identifiers, such as name and birth date.
• Update medical/dental history, medications, and allergies at every visit; coordinate with other treating clinicians.
• Keep complete records with standardized abbreviations understandable to another knowledgeable clinician.
• Obtain parent informed consent and child assent when applicable.
• Before an invasive procedure, pause with the team to confirm patient, procedure, and tooth/site; assess fire risk.
• Document medication indication; review allergies, interactions, current drugs, and dose calculation.

Decision map: resolve mismatch before extraction

Loading diagram…

Use at least two identifiers and an accurate current history/chart. Pause with team members present to confirm patient, procedure, and tooth/site before an invasive procedure. Resolve discrepancies before care; encourage speaking up and examine near misses without suppressing reports. The fire-risk time-out and other safeguards below remain separate required considerations.

Reliable systems and a speaking-up culture

• Error contributors: interruptions, poor communication, fatigue, stress, burnout, incomplete history, and inconsistent workflows.
• Consequences include wrong-site treatment, delayed/missed diagnosis, faulty referral, dosing errors, infection, and swallowed, aspirated, or retained objects.
• Use reviewed procedure manuals, checklists, staff training, and simulation. Electronic reminders/order sets may improve adherence.
• A near miss involves an error without clinical harm; review it as well as adverse events. Record harm severity and analyze causes, patterns, and outcomes.
• Use root-cause analysis to identify corrective actions; reassess improvement in safety and patient satisfaction.
• Encourage reporting and intervention. A just culture preserves personal accountability without blaming staff for system failures beyond their control.
• Provide burnout prevention/recognition training and access to confidential mental health and substance-use support. Protect identifiable patient information used for analysis.

Office and procedural safeguards

• Follow applicable laws and infection-control guidance; prevent transmission in every direction between patients and personnel.
• Inspect facilities, emergency/fire plans, clinical equipment, and maintenance routinely. Toys/play areas create injury and infection risks.
• Source flags objects under 1.25 inches diameter and 2.25 inches length, without compression, as hazardous for children under 3.
• Follow CDC dental waterline guidance for nonsurgical care; use sterile water or saline for surgery.
• Protect the airway with isolation such as rubber dam; track placement/removal of throat packs, cords, cotton pellets, and separators. Use surgical counts and protective eyewear.
• Apply the as low as reasonably achievable (ALARA) principle, radiographic selection criteria, and equipment maintenance. The source describes at least 2 meters (6.5 feet) separation from the radiation source for nearby people.
• Maintain the lowest practical environmental nitrous oxide exposure; inspect delivery equipment and follow patient-selection/delivery guidance.
• Monitor public health threats and follow recognized local/national guidance.

Sedation and anesthesia

• Provide appropriate staffing/supervision; follow AAPD guidance for stabilization, sedation, and general anesthesia.
• Before office sedation/anesthesia, document rationale, consent, parent instructions, dietary precautions, preoperative evaluation, and prescriptions with instructions.
• Regularly test rescue equipment; keep medications unexpired. Dentist and anesthesia provider must communicate airway and safety concerns during treatment.
• Sedation facilities should track adverse events for risk reduction.

Dental fire prevention

During the time out, identify whether oxygen or nitrous oxide, an ignition source, and combustible material could meet near the mouth. Coordinate changes with the anesthesia provider; maintaining oxygenation remains part of the safety decision.

• Fire triangle: ignition + fuel + oxidizer.
  • Ignition sources: bur sparks, laser, or cautery.
  • Fuels: dry gauze, packs, drapes, and petroleum products.
  • Oxidizers: oxygen or nitrous oxide.
• Keep the field moist and avoid dry cutting. Include fire prevention/management in procedural and emergency plans.
• Oxygen pooling means oxygen above room-air 21%. Experts cited recommend concentrations below 30%.
• High-volume suction may reduce pooling; laboratory evidence favored it over Yankauer/saliva ejector. One clinical study found reduction after one minute of high-velocity suction.
• For operative procedures with cautery requiring oxygen, 30% or less at 4 L/min is a suggested limit. Higher oxygen may be acceptable without cautery or when desaturation risk outweighs fire risk.

Discharge and prevention at home

• Give procedure-specific instructions: anesthetic distribution/duration, avoiding soft-tissue injury, postoperative diet, bleeding control, and medication indications/doses.
• After sedation/anesthesia, meet recognized discharge criteria first; explain travel safety, airway observation, nausea/vomiting, activity, and emergency access.
• Counsel on supervised twice-daily brushing with age-appropriate fluoridated toothpaste, teething gel/jewelry risks, and sports mouthguards.

Common board traps

Answer aloud

How is wrong-tooth extraction prevented?

Verify two patient identifiers, the updated record, and the intended tooth, then conduct a team time-out.

• Confirm patient, procedure, and tooth/site before the invasive step.
• Stop and resolve any mismatch before proceeding.
• Standardize the workflow and empower every team member to raise a concern.

What follows a near miss?

Document, analyze contributing system failures, implement correction, and assess whether it works.

• A near miss can reveal a hazard even without clinical harm.
• Encourage reporting in a fair, learning-oriented culture; accountability does not justify blaming people for system faults.
• Use findings to improve protocols, training, and quality measures.

What increases dental fire risk during oxygen delivery?

The simultaneous presence of oxidizer, ignition source, and fuel.

• Oxygen/nitrous can enrich the operative field; burs, lasers, or electrosurgery can ignite dry gauze, throat packs, and other fuels.
• Assess fire risk with the anesthesia team during the time-out.
• Keep the field moist, use high-volume suction when appropriate, and coordinate oxygen delivery with clinical needs.
• Source discussion suggests ≤30% oxygen at 4 L/min for supplemental oxygen with cautery; higher oxygen may be appropriate when desaturation risk exceeds fire risk. This is not a universal oxygen ceiling.

How is foreign-object aspiration or retention reduced?

Protect the airway and account for materials placed in the mouth.

• Use rubber-dam isolation when appropriate.
• Track placement/removal of throat packs, retraction cords, cotton pellets, and orthodontic separators.
• Include procedural counts, protective eyewear, and clear posttreatment instructions in standardized safety processes.
