The feasibility of characterising the effects of dental post-operative discomfort and sensitivity over time.

OBJECTIVES: To assess the feasibility of using short message service text messages to solicit dental patients' experiences of post-operative dental discomfort and sensitivity (PODDS) and whether responses characterise change in PODDS over time. METHODS: Patients were recruited from clinics following routine dental procedures, such as simple restorations or root surface debridement. They completed a short questionnaire collecting information on socio-economic circumstances, their recent experience of PODDS, the acceptability of receiving text message questions and their telephone number. Participants received a short question by text to their telephone for five consecutive days that asked them to respond with an indication (on a 1 to 10 scale) of their experience of PODDS at that time. RESULTS: Questionnaires were completed by 34 participants, of whom text message responses were received from an average of 23.4 participants (min 20, max 26) across the five follow-up days. Regression analyses indicated that PODDS decreased over time (ß = -0.24, 95% CI -0.36 to -0.12). CONCLUSIONS: Text messaging to solicit PODDS is feasible and can potentially be used to assess the efficacy of treatments designed to minimise or reduce PODDS.
