INTRODUCTION: Professional Mechanical Plaque Removal (PMPR) in paediatric patients can be challenging due to limited cooperation and access. The use of plaque disclosing agents (PD) in combination with air-flowing devices employing low-abrasiveness powders has demonstrated improved plaque removal in adults, with additional advantages in terms of comfort and treatment efficiency. This randomized controlled clinical trial evaluated the residual plaque area (RPA) on anterior vestibular sextants after PMPR with and without PD and erythritol-based air-flowing (AF) in children. Secondary outcomes included post-treatment Full Mouth Plaque Score (FMPS), treatment duration and feedback from both patients and the clinicians.
METHODS: A total of 120 children aged 6-12 years were randomized to one of four groups: air-flowing with plaque disclosing (AF + PD), air-flowing alone (AF), rubber cup and polishing paste with plaque disclosing (CUP + PD) or rubber cup and polishing paste alone (CUP). After treatment, PD was reapplied, FMPS was recorded and RPA was assessed via computer-assisted photographic analysis. Treatment time was measured and feedback from patients and clinicians was collected via structured questionnaires.
RESULTS: AF + PD achieved significantly lower RPA-on anterior vestibular sextants-and FMPS values compared with all other methods. CUP took significantly less time but was the least effective for plaque removal. Although all approaches were rated positively, both children and clinicians expressed a preference for AF-based methods.
CONCLUSION: The combination of plaque disclosing and air-flowing significantly enhances plaque removal in paediatric patients, while improving the treatment experience for both patients and clinicians. AF + PD may represent a valuable adjunct to paediatric preventive protocols.
