Outcome Measures

Primary Outcomes (2)

  • Mean score of Feasibility of Intervention Measure (FIM)

    The Feasibility of Intervention Measure (FIM) is a 4-item implementation measure that assesses participants or providers' perceived feasibility of the intervention. Responses are rated on a 5-point Likert scale ranging from 1 (Completely Disagree) to 5 (Completely Agree). The survey is administered at baseline and at each surveillance visit.

    Up to 1 year

  • Interview

    Interview will be conducted with participants and providers using guided questions. Responses will be analyzed to assess the feasibility and potential for expanding the fluoride varnish program.

    Up to one day

Secondary Outcomes (5)

  • Mean Change of Score of Dental Care Practice

    Up to 1 year

  • Mean Change of Score of Familiarity with the Risks of Radiation

    Up to 1 year

  • Change in Saliva potential hydrogen (pH) measure

    Up to 1 year

  • Mean Change of Score of Oral Health-Related Quality of Life (OHRQoL)

    Up to 1 year

  • Mean score Change in Decayed-Missing-Filled Teeth (DMFT) Index

    Up to 1 year

Study Arms (2)

Fluoride Varnish Treatment (Participant)

EXPERIMENTAL

Participants will received Medicom Duraflor Ultra White 5% Sodium Fluoride varnish treatments during their routine cancer surveillance visits every 3-6 month for about 1 year. During these visits, participants will complete short surveys, provide saliva samples, and have photos taken of their teeth before and after the treatment. Health and dental care providers will also be asked to complete a survey about fluoride treatment delivered.

Interview

OTHER

The research team will interviews with participants, caregivers, and healthcare and dental providers.

Other: Interview (Participant)

Interventions

SurveysOTHER

Participants will complete surveys to collect information about their dental health before and after fluoride varnish treatment. Healthcare and dental providers will complete a survey to assess the feasibility of the fluoride varnish treatment.

Fluoride Varnish Treatment (Participant)

Participants will provide a saliva sample for pH measurement.

Fluoride Varnish Treatment (Participant)

Images of participants' teeth will be taken to assess the Decayed, Missing, and Filled Teeth (DMFT) index.

Fluoride Varnish Treatment (Participant)

Participants will receive 4-5 fluoride varnish treatment every 3 month over the course of a year. Treatment is delivered during cancer surveillance visits. Participant will also receive dental care educational materials.

Fluoride Varnish Treatment (Participant)

Participants and caregivers will share their experiences accessing dental care, identify barriers to care, and provide their views on integrating preventive dental care into routine medical care. Healthcare and dental providers will share their observations about patient access to dental care and their views on integrating preventive dental care into routine medical care.
