Efficacy of 3D-Printed Cleaning Splints for Approximal Dental Biofilm Removal-A Randomized Clinical Crossover Pilot Study

Resumo original em inglês

O que aconteceu

This study investigated the effectiveness of biofilm removal using individually customized cleaning splints (CS) as an aid for interdental brushes (IDBs).

In a randomized clinical crossover study, the effect of IDBs in combination with CS on plaque reduction and periodontal parameters was examined. Periodontitis patients received an intraoral scan to produce a 3D-printed CS. Following a 2-week interdental hygiene pause, they were divided into two groups: Group A: CS+IDBs, Group B: IDBs. Participants performed daily interdental cleaning at home for 2 weeks following standardized professional instruction. After another 2-week interdental hygiene pause, the groups switched methods. Additionally, motor skills, stress levels, and nutritional quality were assessed.

O que encontraram

Thirty participants (age range 21-82 years) completed the study. CS+IDBs led to a significantly greater plaque reduction (change in Quigley-Hein plaque index, ∆QHI) compared to IDBs alone (ΔQHI = -1.38 vs. -0.23, p < 0.001). The impact on reducing gingival inflammation (GI) was limited to younger participants with no effect on bleeding on probing (BOP). Random effects ANCOVA confirmed the significant effect of CS on ∆QHI (p < 0.001). An interaction between perceived stress and CS use on BOP indicated that stress may influence the effectiveness of CS supported plaque removal.

Por que isso importa

Cleaning splints are a promising approach to enhance the effectiveness of IDBs in reducing interdental biofilm.
