Aim Assessment of Oral Health Impact Profile (OHIP‐14) during a randomized controlled trial of supportive periodontal therapy (SPT) consisting of oral prophylaxis with oral hygiene instructions only (test) or in conjunction with subgingival instrumentation (control). Methods OHIP‐14 was assessed at baseline, 6, 12, 18 and 24 months. Data from 62 participants (50.97 ± 9.26 years, 24 smokers) were analysed by GEE and Logistic regression. OHIP‐14 means, effect size, floor and ceiling effect and minimal important difference were calculated. Sum of OHIP‐14 (severity), numbers of responses (extent) “fairly often” (FO) or “very often” (VO) and percentage of people (prevalence) reporting FO or VO were computed. Results At baseline, low scores of OHIP‐14 were observed for test (7.67 ± 9.27) and control (6.51 ± 7.47) with a decreasing trend during SPT, without differences between or intra‐groups over time. At 6 months, a difference was observed in the OHIP‐14 prevalence ( p = .03), without differences in severity and extent. Smoking status and plaque >15% (moderate oral hygiene) at 24 months were associated with higher OHIP‐14 prevalence scores at that point of time ( p = .038 and p = .034, respectively). Conclusion Patients submitted to two different modalities of SPT maintained low OHIP‐14 scores over 2 years of care.
