These are conditions where tooth extraction should be avoided due to overall health concerns:

• Cardiac Diseases:

  • Valvular, Rheumatic, or Ischemic heart disease
  • Congestive heart failure
  • Hypertension
  • Patients on anticoagulation therapy

• Blood Diseases:

  • Severe anemia
  • Leukemia
  • Hemophilia
  • Agranulocytosis

• Addison’s Disease

• Patients on Corticosteroids:

  • Requires dose adjustment

• Liver Diseases:

  • Jaundice and liver disease
  • Vitamin K deficiency
  • Blood clotting factor deficiencies (Prothrombin, Fibrinogen)

• Diabetes Mellitus:

  • Poor wound healing due to decayed healing processes

• Thyrotoxicosis

• Pregnancy:

  • Especially during the first and third trimesters
  • Risks of abortion, premature delivery
  • Gravid uterus causing discomfort
  • Reduced stamina for opening the mouth

• Very Old Age:

  • Decreased physiological response
  • Non-healing tissues and increased risk of infection

• Epileptic Patients

• Presence of Fever:

  • Infections can complicate healing

• Debilitating Diseases:

  • Tuberculosis
  • Car pulmonale
  • Asthma
  • Nephritis

• Psychosis/Neurosis:

  • Mental health conditions affecting cooperation

• Allergy to Local Anesthetics (LA)

• Incorporative Patients:

2. Local Contraindications

These are conditions that affect the immediate area of the tooth that may cause complications:

• Acute Infections:

  • Presence of infection at the extraction site

• Malignancy:

  • Growth may spread rapidly after the procedure

• Irradiated Jaw:

  • Risk of acute osteoradionecrosis due to lack of blood supply (endarteritis obliterans)

3. Absolute Contraindications

Certain conditions make tooth extraction entirely inappropriate:

• Hemangioma:

  • Increased risk of bleeding

• Arteriovenous Malformation (AV Malformation):

  • Bleeding that cannot be controlled

• In the case of such conditions, if extraction is necessary:

  • Place the tooth back in the socket and apply pressure to control bleeding

4. Relative Contraindications

These are conditions where tooth extraction may be performed with caution or special consideration:

• Diabetes Mellitus:

  • May require special management due to healing concerns

• Valvular Heart Disease:

  • And other similar conditions where dental management requires careful planning and monitoring
