Advices for Ca Patients

• Brush teeth, gums, and tongue gently with an extra-soft toothbrush and fluoride toothpaste after every meal and at bedtime. If brushing hurts, soften the bristles in warm water.

• Floss teeth gently every day. If your gums bleed and hurt, avoid the areas that are bleeding or sore but keep flossing your other teeth.

• Follow instructions for fluoride gel applications.

• Avoid mouthwashes containing alcohol.

• Rinse the mouth several times a day with a baking soda and salt solution, followed by a plain water rinse. Use ¼ teaspoon each of baking soda and salt in 1 quart of warm water. Omit salt during mucositis.

Try the following if dry mouth is a problem:

• Sip water frequently.

• Suck ice chips or use sugar-free gum or candy.

• Use saliva substitute spray or gel or a prescribed saliva stimulant if appropriate.

• Avoid glycerin swabs.

• Exercise the jaw muscles three times a day to prevent and treat jaw stiffness from radiation treatment.

• Avoid candy, gum, and soda unless they are sugar-free.

• Avoid spicy or acidic foods, toothpicks, tobacco products, and alcohol.

Head and Neck Radiation Therapy

Patients receiving radiation therapy to the head and neck are at risk for developing oral complications. Because of the risk of osteonecrosis in irradiated fields, oral surgery should be performed before radiation treatment begins.

Before Head and Neck Radiation Therapy

• Conduct a pretreatment oral health examination and prophylaxis.

• Schedule dental treatment in consultation with the radiation oncologist.

• Extract teeth in the proposed radiation field that may be a problem in the future.

• Prevent tooth demineralization and radiation caries:

  • Fabricate custom gel-applicator trays for the patient.

  • Prescribe a 1.1% neutral pH sodium fluoride gel or a 0.4% stannous, unflavored fluoride gel (not fluoride rinses).

  • Use a neutral fluoride for patients with porcelain crowns or resin or glass ionomer restorations.

  • Be sure that the trays cover all tooth structures without irritating the gingival or mucosal tissues.

  • Instruct the patient in home application of fluoride gel. Several days before radiation therapy begins, the patient should start a daily 10-minute application.

  • Have patients brush with a fluoride gel if using trays is difficult.

• Allow at least 14 days of healing for any oral surgical procedures.

• Conduct prosthetic surgery before treatment, since elective surgical procedures are contraindicated on irradiated bone.

Chemotherapy

The oral complications of chemotherapy depend upon the drugs used, the dosage, the degree of dental disease, and the use of radiation. Chemoradiation therapy carries a significant risk for mucositis.

Before Chemotherapy

• Conduct a pretreatment oral health examination and prophylaxis.

• Schedule dental treatment in consultation with the oncologist.

• Schedule oral surgery at least 7 to 10 days before myelosuppressive therapy begins.

• Consult the oncologist before conducting any oral procedures in patients with hematologic cancers; do not conduct procedures in patients who are immunosuppressed or have thrombocytopenia.

During Chemotherapy

• Consult the oncologist before any dental procedure, including prophylaxis.

• Ask the oncologist to order blood work 24 hours before oral surgery or other invasive procedures. Postpone when

  • the platelet count is less than 75,000/mm³ or abnormal clotting factors are present

  • absolute neutrophil count is less than 1,000/mm³, or consider prophylactic antibiotics

• Check for oral source of viral, bacterial, or fungal infection in patients with fever of unknown origin.

• Encourage consistent oral hygiene measures.

• Consult the oncologist about the need for antibiotic prophylaxis before any dental procedures in patients with central venous catheters.

Hematopoietic Stem Cell Transplantation

Most stem cell transplant patients develop acute oral complications, especially patients with graft-versus host disease.

Before Transplantation

• Conduct a pretreatment oral health examination and prophylaxis.

• Consult the oncologist about scheduling dental treatment.

• Schedule oral surgery at least 7 to 10 days before myelosuppressive therapy begins.

• Prevent tooth demineralization and radiation caries:

  • Instruct the patient in home application of fluoride gel (not fluoride rinses).

• Instruct the patient about an oral hygiene regimen.

After Transplantation

• Consult the oncologist before any dental procedure, including prophylaxis.

• Monitor the patient’s oral health for plaque control, tooth demineralization, dental caries, and infection.

• Watch for infections on the tongue and oral mucosa. Herpes simplex and Candida albicans are common oral infections.

• Delay elective oral procedures for 1 year.

• Follow patients for long-term oral complications. Such problems are strong indicators of chronic graft-versus-host disease.

• Monitor transplant patients carefully for second malignancies in the oral region.
