Dental Pick Injury

CASE STUDY: OCULAR PENETRATION FROM A DENTAL PICK DURING ROUTINE TEETH CLEANING

EXAMINATION UPON ARRIVAL AT THE BOCHNER EYE INSTITUTE

BEST-CORRECTED VISUAL ACUITY:

• Right Eye: Counting fingers at 2 feet
• Left Eye: 20/20

EXTERNAL EXAMINATION:

• Mild eyelid edema, no ecchymosis

SLIT-LAMP FINDINGS:

• Corneal perforation in the midperiphery
• Irregular pupil due to iris laceration
• Traumatic cataract with disrupted anterior capsule
• 1-2 mm hyphema
• No view of the posterior segment

INTRAOCULAR PRESSURE:

• Right Eye: 9 mmHg
• Left Eye: 15 mmHg

DIAGNOSIS:

• Penetrating injury to the cornea, iris, and lens
• Traumatic cataract and hyphema

EMERGENCY TREATMENT:

• Eye shield applied
• Topical and oral antibiotics
• NPO initiated

EMERGENT SURGICAL REPAIR:

• Corneal wound closure with three 10-0 nylon sutures
• Iris repositioning

ONE MONTH LATER:

• Removal of traumatic cataract and insertion of toric implant

POST-OPERATIVE COURSE:

• No signs of infection or retinal involvement
• Best-corrected visual acuity improved from CF to 20/40
• Patient reported significant emotional distress and is considering legal action against dental provider

DISCUSSION: IMPORTANCE OF EYE PROTECTION IN DENTAL SETTINGS

This case underscores the significant risk of ocular trauma in dental environments, even during routine procedures. The dropped dental pick caused a penetrating open-globe injury with lasting visual consequences. It highlights the need for heightened awareness regarding the potential for such injuries and the necessity of proper patient protection.

KEY SAFETY CONSIDERATIONS:

1. Risk Underestimation in Dentistry:

Although dental instruments are not high-velocity tools, their sharpness and proximity to the eye make them a significant hazard. Routine procedures that involve the use of sharp or pointed instruments must account for the potential risks they pose.

2. Protective Eyewear Should Be Mandatory:

Protective glasses should be worn by all patients during dental procedures, regardless of perceived risk. Eye protection is an essential preventive measure that can drastically reduce the likelihood of ocular trauma.

3. Regulatory and Ethical Responsibility:

Dental clinics have a professional duty to anticipate and mitigate preventable injuries. The failure to offer eye protection can be seen as a breach of professional standards, and dental practitioners must ensure they meet the ethical requirements of care.

4. Cost of Non-Compliance:

Beyond the immediate risk of patient morbidity, failure to provide adequate eye protection can lead to significant legal liability, reputational damage, and potential regulatory consequences.

5. Educational Imperative:

Dental training programs and continuing education should emphasize the importance of patient eye protection. This should be particularly highlighted when using sharp instruments, ensuring that all dental practitioners are aware of their responsibility to protect patients during routine procedures.

FINAL THOUGHTS:

This case serves as a potent reminder of the importance of simple yet effective preventive measures in healthcare settings. Ocular trauma, while often avoidable, can have severe consequences. By incorporating basic safety protocols such as the use of protective eyewear for patients, dental practices can safeguard against potentially life-altering injuries.

Additionally, the broader medical community, including dental professionals, must prioritize ongoing education to raise awareness of the risks and responsibilities inherent in patient care. In doing so, we not only mitigate preventable injuries but also enhance patient trust and improve overall care standards.
