Untreated dental disease and lung transplant waitlist evaluation time for individuals with cystic fibrosis.

AIMS

Dental clearance is typically part of the evaluation process prior to placement on the lung transplant waiting list. Individuals with cystic fibrosis (CF) are thought to be at low risk for dental disease. We hypothesized that individuals with CF in need of lung transplantation would have lower dental disease prevalence and shorter waitlist evaluation time than individuals with non-CF lung diseases.

METHODS AND RESULTS

We conducted a retrospective study of individuals who received a lung transplant between 2011 and 2017 at the University of Washington (Seattle, WA, USA) (N = 280). Untreated dental disease was assessed by the individual's dentist. Waitlist evaluation time was defined as the time, in days, from the initial evaluation by a transplant pulmonologist to placement on the lung transplant waiting list. We used logistic and linear regression models for hypothesis testing. The prevalence of untreated dental disease did not differ by CF status (p = 0.99). There was no difference in waitlist evaluation time for transplant recipients by CF status (p = 0.78) or by dental disease status (p = 0.93).

CONCLUSIONS

Our findings provide further evidence that individuals with CF are not at low risk for dental disease. Ensuring optimal oral health is important for all individuals with lung diseases.
