An in vivo comparative study on the efficiency of a disclosing dye and a gel in detection of dental plaque among pediatric patients

Introduction:

Dental plaque is a key factor in the development of caries and periodontal disease, particularly in children due to their developing oral hygiene habits. Disclosing agents are effective tools for visualizing plaque accumulation. While both disclosing dyes and gels are widely used, comparative evidence regarding their effectiveness in paediatric patients is limited.

Objective:

To compare the effectiveness of a disclosing dye and a disclosing gel in detecting dental plaque among paediatric patients and evaluate their plaque visibility, ease of application, and acceptance by both patients and operators.

Methodology:

A randomized in vivo study was conducted in children aged 6–13 years. Participants were equally divided into two groups: disclosing gel group (erythrosine gel) and disclosing dye group (two-tone dye). Each participant underwent plaque disclosure, with application time recorded. Clinical examination was performed using the Turesky Modification of the Quigley-Hein Plaque Index. Plaque visibility, ease of use, and acceptance were assessed using a Likert scale.

Results:

Both agents effectively disclosed plaque. However, the gel group demonstrated significantly higher mean plaque scores, indicating better visualization. The gel was also preferred for its pleasant taste, controlled flow, and ease of use, leading to higher patient and operator acceptance.

Conclusion:

The erythrosine disclosing gel proved more effective than the traditional dye in detecting plaque and was better accepted by paediatric patients. It is recommended as a superior tool for plaque assessment and oral hygiene education in children
