Final answer:
The initial treatment for lateral periodontal abscess involves draining the abscess and prescribing antibiotics such as penicillin or amoxicillin, with anti-inflammatory drugs for severe cases and follow-up dental care.
Step-by-step explanation:
Initial Treatment for Lateral Periodontal Abscess
The initial treatment for a patient with a lateral periodontal abscess should include the drainage of the abscess to reduce the localized infection. Additionally, oral or intravenous antibiotics such as penicillin, or for more severe cases, anti-inflammatory medications may be prescribed. Proper oral hygiene and possibly follow-up dental care to address the underlying periodontal disease is crucial. If the abscess is associated with more advanced periodontal issues like trench mouth, characterized by ulcerations and halitosis, antibiotics such as amoxicillin, amoxicillin clavulanate, clindamycin, or doxycycline may be required along with professional cleaning and pain management.
