ABSTRACT:
Gangrenous pulpitis is a severe dental condition requiring careful management in
pregnant women to ensure maternal and fetal safety. This paper explores diagnostic methods,
root canal therapy, conservative treatments, and safe pharmacological interventions. The
importance of minimizing stress, using pregnancy-safe medications, and employing alternative
techniques such as laser therapy is highlighted. A multidisciplinary approach integrating
preventive care and psychological support is essential for optimal outcomes, ensuring effective
infection control while safeguarding both maternal and fetal health.
Keywords:

Gangrenous pulpitis is a severe dental condition characterized by the necrosis of the dental pulp,
leading to infection, pain, and potential complications if left untreated. It is a serious form of
irreversible pulpitis, often resulting from untreated caries or chronic inflammation of the pulp.
Pregnant women are particularly vulnerable to dental infections due to hormonal changes that
affect the immune system, increase blood flow to the gums, and alter the composition of saliva,
which can lead to a higher risk of bacterial growth in the oral cavity. Additionally, pregnancy-
induced nausea and vomiting can expose teeth to gastric acids, further weakening enamel and
making them more susceptible to infections. Treating gangrenous pulpitis in pregnant women
requires a careful approach to ensure the safety of both the mother and the developing fetus. The
treatment plan must consider the gestational period, the use of safe medications, and the
avoidance of any procedures that might induce stress or harm. Due to the complex physiological
changes during pregnancy, healthcare providers must work in collaboration to develop an
effective yet safe treatment strategy, integrating conservative and pharmacological approaches
while minimizing risks associated with anesthesia, radiographic imaging, and medication use.
The first step in managing gangrenous pulpitis in pregnant women is proper diagnosis, which
must be conducted with minimal radiation exposure. Radiographic imaging is crucial for
assessing the extent of pulp necrosis and the presence of periapical lesions. However, since
radiation exposure during pregnancy can pose risks to fetal development, it is essential to use
lead aprons and thyroid collars to shield the mother and fetus from unnecessary exposure. Digital
radiography, which emits lower doses of radiation compared to conventional X-rays, is the
preferred diagnostic tool. Clinical examination remains an essential component of the diagnostic
process, with symptoms such as spontaneous pain, foul odor from the affected tooth, and
purulent discharge being key indicators of gangrenous pulpitis. Once the condition is confirmed,
treatment must be initiated promptly to prevent systemic infection, which could pose additional
risks during pregnancy.

The primary treatment option for gangrenous pulpitis is root canal therapy (RCT), which aims to
remove the necrotic pulp tissue, disinfect the root canals, and seal the tooth to prevent reinfection.
RCT is generally safe during pregnancy when performed with proper precautions. The ideal time
for endodontic treatment is the second trimester, as the first trimester is a critical period for fetal
organ development, and the third trimester poses risks of inducing premature labor due to stress
or prolonged positioning of the patient. Local anesthesia is necessary for pain management
during RCT, and the use of category B anesthetics such as lidocaine with epinephrine in low
doses is considered safe. Epinephrine should be used cautiously, as excessive doses can lead to
vasoconstriction, reducing blood flow to the placenta. The use of rubber dams during RCT is
essential to prevent the ingestion of debris and medicaments, ensuring patient comfort and safety.
The choice of irrigants and intracanal medicaments is another crucial aspect of treatment.
Sodium hypochlorite, the most commonly used irrigant, should be used with caution, avoiding
excessive concentrations that could cause tissue irritation. Calcium hydroxide, a safe intracanal
medicament with antimicrobial properties, is preferred for temporary dressing in pregnant
patients, as it promotes healing and is biocompatible.
In cases where RCT is not immediately feasible due to the patient’s condition or gestational
limitations, palliative treatments such as pulpectomy or pulpotomy may be performed to alleviate
pain and control infection. A pulpectomy involves the complete removal of the necrotic pulp
tissue, while a pulpotomy removes only the coronal pulp, leaving the radicular pulp intact. These
procedures provide temporary relief until definitive treatment can be completed. If the infection
is severe and spreading, extraction may be considered as a last resort, especially if the tooth is
non-restorable. However, extractions should be approached with caution, as the stress and
discomfort associated with tooth removal could affect the pregnant patient’s overall well-being.
Post-extraction care should include proper pain management using acetaminophen, which is the
preferred analgesic during pregnancy, while avoiding nonsteroidal anti-inflammatory drugs
(NSAIDs) such as ibuprofen, especially in the third trimester due to their association with fetal
cardiovascular complications.
Antibiotic therapy may be necessary in cases of severe infection or abscess formation. The
choice of antibiotics should prioritize safety for both the mother and fetus. Penicillin and
amoxicillin, with or without clavulanic acid, are commonly prescribed as first-line antibiotics
due to their established safety profile. Clindamycin may be used in patients allergic to penicillin.
Tetracyclines and fluoroquinolones should be strictly avoided, as they can cause fetal skeletal
and dental defects. Antibiotic therapy should be prescribed for the shortest effective duration to
minimize unnecessary exposure to medications. Additionally, pregnant patients should be
advised on proper oral hygiene practices to prevent further infections. Brushing twice a day with
fluoride toothpaste, using an antimicrobial mouthwash, and maintaining a balanced diet rich in
calcium and vitamin D can support oral health during pregnancy.
Pregnant women with gangrenous pulpitis may also benefit from adjunctive treatments such as
laser therapy, which has been explored as an alternative to traditional root canal disinfection
methods. Laser-assisted endodontics has shown promising results in reducing bacterial load
within root canals while minimizing the use of chemical irrigants. However, due to limited
studies on the safety of laser therapy during pregnancy, its application should be carefully
evaluated. Similarly, photodynamic therapy, which utilizes light-activated antimicrobial agents,
has been proposed as a potential treatment for infected root canals, offering a non-invasive
approach that reduces the need for extensive chemical interventions. Further research is required
to establish the safety and efficacy of these emerging treatment modalities in pregnant patients.
In conclusion, the treatment of gangrenous pulpitis in pregnant women requires a
multidisciplinary approach that balances effective infection control with maternal and fetal safety.
Root canal therapy remains the gold standard treatment, with careful selection of anesthetics,

irrigants, and medications to minimize risks. Conservative procedures such as pulpotomy or
pulpectomy may serve as temporary solutions when definitive treatment is delayed. Antibiotic
therapy should be prescribed judiciously, focusing on pregnancy-safe medications. Emerging
technologies such as laser therapy and photodynamic therapy offer promising alternatives,
though further research is needed. Ultimately, preventive care, patient education, and stress
management strategies are key to maintaining optimal oral health in pregnant women, reducing
the risk of severe dental infections and ensuring a smooth pregnancy journey.
