Plaque and gingival status as indicators for caries progression on approximal surfaces

Area of Science:

• Dental Research
• Cariology
• Periodontology

Background:

• Approximal dental caries progression is a significant concern in young adults.
• Predictive markers for lesion advancement are essential for timely intervention.
• Plaque accumulation and gingival inflammation are commonly assessed oral health parameters.

Purpose of the Study:

• To assess plaque and gingival status on sound and carious approximal tooth surfaces.
• To determine if these parameters can predict the progression of approximal caries.
• To investigate the relationship between plaque, gingival status, and caries progression.

Main Methods:

• Two patient samples (18-25 years old) were recruited.
• Sample 1: Plaque and gingival status recorded once on sound and carious surfaces.
• Sample 2: Plaque and gingival status recorded repeatedly over 15 months; caries progression assessed via serial examinations.

Main Results:

• Plaque accumulation was high on both sound and carious surfaces, with no significant difference.
• Gingival status differed significantly, with bleeding after probing associated with carious surfaces.
• In Sample 2, bleeding after probing was significantly related to caries progression, unlike plaque scores.

Conclusions:

• Gingival bleeding after probing is a more reliable predictor of approximal caries progression than plaque accumulation.
• Plaque presence alone does not strongly indicate future lesion advancement.
• Clinical assessment of gingival bleeding is valuable for identifying patients at risk of caries progression.
