What are the dental care recommendations for a pregnant patient with significant dental concerns, such as those classified under Ellis Class III?

Dental Care Recommendations for Pregnant Patients with Ellis Class III Dental Concerns

Dental treatment for pregnant patients with Ellis Class III fractures or other significant dental concerns should be performed during the second trimester (weeks 17-28) when possible, with emergency treatment permissible throughout pregnancy to address pain or infection.

Understanding Ellis Class III Fractures During Pregnancy

Ellis Class III fractures involve fractures that extend into the dentin and expose the dental pulp, requiring prompt intervention to prevent infection and pain. When these occur during pregnancy, special considerations apply:

• Pregnancy causes physiological changes that can impact oral health, including increased inflammatory response that may aggravate existing dental conditions 1
• Organogenesis occurs during the first trimester, making this period more susceptible to potential teratogenic effects from medications or procedures 1
• The second trimester (weeks 17-28) is the ideal time for performing dental treatment, balancing maternal and fetal safety 1

Safety of Dental Procedures During Pregnancy

• Preventive and restorative dental treatments are generally safe during pregnancy 1, 2
• Diagnostic radiographs may be performed after the first trimester if absolutely necessary, with appropriate shielding 1, 3
• For Ellis Class III fractures requiring endodontic treatment, periapical radiographs are mandatory for diagnosis, treatment planning, and follow-up 3
• When 2D imaging is insufficient to clarify anatomical relationships, CBCT may be considered, but should be as targeted as possible following the ALARA principle 3

Medication Considerations

• Local anesthetics such as lidocaine are considered safe during pregnancy 1
• For pain management, acetaminophen (paracetamol) is the preferred analgesic 4, 1
• If antibiotics are needed for infection control, amoxicillin, ampicillin, and certain cephalosporins and macrolides can be prescribed 1
• Avoid tetracyclines, which can cause tooth discoloration in the developing fetus 4

Treatment Approach for Ellis Class III Fractures

• Emergency treatment for acute pain or infections is necessary and can be performed throughout pregnancy 1
• Proper infection control practices must be maintained, including appropriate use of gloves, masks, and protective eyewear 3
• For pulp exposure (Ellis Class III):
  • Pulp capping, pulpotomy, or root canal treatment may be necessary depending on the extent of exposure 3
  • Complete treatment in a timely manner to prevent infection that could affect both mother and fetus 2

Barriers to Dental Care During Pregnancy

• Financial limitations are the main barrier to receiving dental care during pregnancy, with only 44% of pregnant women receiving care despite 84% believing it's safe 5
• Many dentists are reluctant to provide treatment due to lack of information about safety protocols 1, 5
• Only 56% of women report having a dental cleaning visit before pregnancy, and this number drops to 47% during pregnancy 6

Recommendations for Dental Providers

• Screen every pregnant woman for oral health risks 2
• Provide counseling on proper oral hygiene 2
• Schedule non-emergency procedures during the second trimester when possible 1
• Maintain open communication with the patient's obstetrician, especially for patients with severe infections or complications 4
• Ensure proper positioning during dental procedures to avoid supine hypotension syndrome (avoid lying flat on back) 7
• Promote preventive dental visits before pregnancy, as women who receive dental care before pregnancy are significantly more likely to seek care during pregnancy 6

Patient Education

• Emphasize the importance of oral health during pregnancy and its potential impact on pregnancy outcomes 2, 6
• Explain that poor dental hygiene may be associated with adverse pregnancy outcomes such as preterm birth and low birth weight 2, 6
• Reassure patients about the safety of necessary dental procedures during pregnancy 5
• Encourage routine dental visits before conception as part of preconception care 3, 6
