What are the risks of dental procedures in children with an uncomplicated clinical diagnosis of Ehlers-Danlos Syndrome (EDS)?

Dental Procedures in Children with Uncomplicated EDS: Risk Assessment

For children with uncomplicated (non-vascular) EDS subtypes, dental procedures can be performed safely with specific precautions for tissue fragility, bleeding risk, and temporomandibular joint (TMJ) instability, but do not require the extreme caution necessary for vascular EDS. 1, 2

Critical First Step: Determine EDS Subtype

The single most important factor is identifying whether the child has vascular EDS (Type IV) versus other subtypes (hypermobile, classical). This distinction fundamentally changes risk stratification:

• Vascular EDS carries extreme surgical risk due to arterial fragility, spontaneous bleeding, and tissue rupture 3, 4
• Hypermobile and classical EDS have manageable dental risks related primarily to tissue fragility and joint issues 1, 2
• If subtype is uncertain, genetic testing should be obtained before elective procedures 3

Specific Risks in Non-Vascular EDS

Tissue and Bleeding Complications

Mucosal fragility is universal in EDS and requires gentle tissue handling during all dental procedures. 1 Key concerns include:

• Increased mucosal tearing with routine instrumentation 1
• Poor wound healing and delayed tissue repair 3, 1
• Prolonged bleeding time in some EDS subtypes (particularly Type VIII) 5
• Higher risk of gingival trauma during routine cleaning 1

For children with documented bleeding abnormalities, desmopressin (DDAVP) pretreatment corrects bleeding time and enables safe dental procedures. 5 This should be considered when bleeding history is positive.

Temporomandibular Joint Risks

All EDS patients are at high risk for TMJ dislocation during dental procedures requiring prolonged mouth opening. 1, 2 The evidence shows:

• 100% of EDS subjects in one study were symptomatic for TMJ disorders with recurrent dislocations 1
• Joint hypermobility affects the mandible as severely as other joints 2
• Limit mouth opening duration and use bite blocks to prevent excessive jaw displacement 1, 2

Periodontal and Dental Considerations

Children with EDS demonstrate significantly compromised oral health:

• 62% have high periodontal treatment needs (CPITN = II) 1
• Higher caries experience compared to controls, related to poor oral hygiene from mucosal fragility and wrist joint mobility limitations 1
• Early severe periodontitis can occur, particularly in Type VIII 5, 6
• Pulp calcifications (78%) and abnormal pulp shape (13%) in classical EDS 1

Practical Management Protocol

Preoperative Assessment

1. Confirm EDS subtype through genetic testing if not already documented 3
2. Obtain bleeding history and consider DDAVP if prolonged bleeding reported 5
3. Assess TMJ stability and history of dislocations 1
4. Document baseline periodontal status 1, 6

Intraoperative Precautions

Use meticulous, gentle tissue handling throughout the procedure to minimize trauma. 3, 1 Specific techniques include:

• Minimize retraction force on oral mucosa 3
• Use pledgeted sutures if tissue repair is needed to prevent tearing through fragile tissues 3
• Limit mouth opening time and use supportive devices 1, 2
• Avoid excessive instrumentation pressure 1

Postoperative Monitoring

• Anticipate delayed wound healing and plan extended follow-up 3, 1
• Monitor for bleeding complications beyond typical timeframes 5
• Provide detailed wound care instructions emphasizing gentle oral hygiene 1

Endocarditis Prophylaxis Consideration

Antibiotic prophylaxis for dental procedures is NOT routinely indicated for EDS alone. 7 The 2015 AHA guidelines restrict prophylaxis to:

• Previous infective endocarditis
• Prosthetic cardiac valves
• Certain congenital heart defects (unrepaired cyanotic CHD, repaired CHD with prosthetic material in first 6 months)
• Cardiac transplant recipients with valvulopathy 7

EDS patients only require prophylaxis if they have one of these specific cardiac conditions, not based on EDS diagnosis itself. 7

Critical Pitfalls to Avoid

• Never proceed with dental procedures in suspected vascular EDS without genetic confirmation and multidisciplinary consultation 3, 4
• Do not use standard mouth opening techniques without TMJ support 1, 2
• Avoid aggressive periodontal instrumentation that could cause excessive mucosal trauma 1
• Do not assume normal healing timeframes—plan extended monitoring 3, 1
• Avoid opioids for postoperative pain due to high dependence risk and GI complications common in EDS 3, 8

When to Refer or Defer

Defer elective dental procedures and obtain immediate multidisciplinary consultation if:

• Vascular EDS is suspected or confirmed 3, 4
• History of unexplained bleeding complications 5
• Severe TMJ instability with frequent dislocations 1
• Complex surgical procedures are needed (extractions, periodontal surgery) 3, 6

For uncomplicated hypermobile or classical EDS, routine dental care can proceed with the precautions outlined above in a general dental setting. 1, 2
